The body fat index, also known as body fat percentage, is a quantitative measure that expresses the proportion of an individual’s total body weight that is composed of fat tissue. This index provides a more accurate assessment of body composition than traditional measures such as body mass index (BMI), as it specifically accounts for the amount of adipose tissue relative to other body components, such as muscle, bones, and organs. Body fat percentage is a crucial metric in evaluating an individual’s overall health and fitness.

How is the Body Fat Index calculated?

Body fat percentage can be calculated using various methods, ranging from simple and less accurate to more sophisticated and precise. Here are some common techniques:

Calipers/Skinfold Measurements

  • This method involves using calipers to measure the thickness of skinfolds at specific locations on the body (typically triceps, abdomen, and thigh).
  • The measurements are then used in various equations to estimate the percentage of body fat.

Bioelectrical Impedance Analysis (BIA)

  • BIA devices send a low-level electrical current through the body and measure the resistance encountered by the electrical flow.
  • Because fat tissue conducts electricity differently than lean tissue, the impedance can be used to estimate body fat percentage.
  • Smart bathroom scales are using BIA for determining Body Fat Index values.
  • Smart scales use BIA to determine Body Fat Index

3D Body Scanning

  • Advanced 3D scanning technologies can create a detailed model of the body, and software algorithms estimate body fat percentage based on the distribution of fat and lean mass.

It’s important to note that the accuracy of these methods can vary, and factors such as hydration levels, ethnicity, and age can influence the results. For the most accurate and consistent measurements, it’s advisable to use the same method consistently and under similar conditions.

They are heavily involved in movements like running, jumping, and lunging, which are essential for tennis players during rallies and court coverage.

Quadriceps

Hamstrings: The hamstrings  (biceps femoris, semitendinosus, semimembranosus) are located on the back of the thigh. They work in conjunction with the quadriceps to provide stability during movements and are particularly engaged during deceleration and changes of direction on the court.

Gluteal Muscles: The gluteal muscles, including the gluteus maximus, gluteus medius, and gluteus minimus, are situated in the buttocks. They play a vital role in generating power for explosive movements, such as sprinting, jumping, and lateral shuffling.

Calves: The calf muscles, consisting of the gastrocnemius and soleus, are found in the lower leg. They are essential for pushing off the ground during movements like sprinting and jumping, as well as for maintaining balance during various strokes.

Adductors: The adductors are a group of muscles on the inner thigh. They assist in stabilizing the hips during lateral movements and provide support when moving side to side on the tennis court.

Abductors: The abductors are located on the outer hip and are responsible for moving the leg away from the midline of the body. They contribute to lateral movements and maintaining balance during quick changes of direction.

Hip Flexors: The hip flexor muscles, including the iliopsoas and rectus femoris, are located at the front of the hip. They play a crucial role in bringing the thigh toward the abdomen, aiding in movements like running, lunging, and explosive shots.

Hip Rotators: The hip rotator muscles are deep muscles that allow the hip joint to rotate. They are essential for generating torque during rotational movements, such as hitting forehands and backhands.

Tensor Fasciae Latae (TFL): The TFL is a small muscle located on the side of the hip. It helps stabilize the hip and assists in movements like lateral shuffling and side-to-side footwork on the tennis court.

To train all these lower muscles, plyometric exercises, lunges, and squats are essential for developing these muscles and enhancing a player’s ability to change direction rapidly. A well-conditioned lower body is crucial for dynamic movements and efficient court coverage during matches.

Shoulder and Arm Muscles: Powering the Serve and Groundstrokes

The serving motion in tennis involves a series of complex movements that demand robust shoulder and arm muscles. The rotator cuff, deltoids, and triceps work together to produce the power and accuracy required for a dominant serve. Likewise, groundstrokes such as forehands and backhands rely on these muscles to generate topspin and pace. Tennis players often incorporate weight training and resistance exercises, such as shoulder presses and bicep curls, to develop the necessary strength and endurance in these muscle groups.

Tennis players rely heavily on their shoulder and arm muscles to execute powerful serves, accurate groundstrokes, and precise volleys. Here is a list of the shoulder and arm muscles commonly used by tennis players:

Deltoid Muscles: The deltoid muscles are located on the outer side of the shoulder and consist of three parts: anterior deltoid, middle deltoid, and posterior deltoid. They play a crucial role in shoulder movement and stability, allowing tennis players to raise and rotate their arms during various strokes.

Rotator Cuff Muscles: The rotator cuff is a group of four small muscles – supraspinatus, infraspinatus, teres minor, and subscapularis – that stabilize the shoulder joint. These muscles are particularly important in providing control and support during the serving motion and various overhead shots.

Biceps Brachii: The biceps brachii, commonly known as the biceps, is a muscle located in the front of the upper arm. It plays a significant role in bending the elbow, which is crucial in executing shots like forehands and backhands.

Triceps Brachii: The triceps brachii is a muscle located at the back of the upper arm. It is responsible for straightening the elbow and provides the power necessary for shots like serves and backhand strokes.

Brachialis: The brachialis is a muscle located underneath the biceps, between the upper arm bone (humerus) and the forearm bone (ulna). It assists in elbow flexion and contributes to shot power, particularly in forehands.

Brachioradialis: The brachioradialis is a muscle on the forearm that contributes to forearm rotation and elbow flexion. It plays a role in generating power for various shots.

Pronator Teres and Pronator Quadratus: These muscles are responsible for forearm rotation and assist in generating spin on the tennis ball during strokes like topspin forehands.

Wrist Flexors and Extensors: The wrist flexor and extensor muscles are located on the forearm and are vital for controlling the racquet and generating wrist snap, which impacts the spin and direction of shots.

Focusing on Anatomy

In a Formula 1 race, several muscles are highly engaged due to the physical demands placed on the drivers. We saw earlier a few examples of races that pushed the drivers even closer to the limit in the aim to control the car in less than ideal conditions. While battling severe weather conditions aiming to better control the car, physical performance and skills are showing their value in the field. Here are some of the most commonly used muscles during a formula 1 race:

Neck Muscles

The neck muscles, including the sternocleidomastoid, trapezius, and scalene muscles, play a crucial role in supporting the head and maintaining stability during high-speed turns, acceleration, and deceleration. This can be noticed very well as usually the size of a formula 1 driver neck size is significantly expanding in the first years of joining the sport category.

Forearm and Hand Muscles

The muscles in the forearms and hands, such as the flexor and extensor muscles, are constantly active as drivers grip the steering wheel and execute precise gear shifts.

Core Muscles

The core muscles, which include the abdominals, obliques, and lower back muscles, provide stability and support to the driver’s torso during rapid changes in direction, braking, and acceleration.

Leg Muscles

The leg muscles, particularly the quadriceps, hamstrings, and calf muscles, are engaged during braking and acceleration, as well as controlling the pressure applied to the pedals.

Gluteal Muscles

The gluteal muscles, including the gluteus maximus and gluteus medius, assist in stabilizing the hips and generating power during acceleration and cornering.

Cardiovascular System

Although not a specific muscle, the cardiovascular system plays a vital role in a Formula 1 race. The heart and blood vessels work together to deliver oxygen and nutrients to the active muscles, ensuring endurance and performance throughout the race.

It’s important to note that the level of muscle engagement can vary depending on the specific circuit, driving style, and racing conditions. Drivers undergo specific training to develop these muscles, improve endurance, and maintain control of the car throughout the race.

General Training Regime

We learned about the limits of a Formula 1 Driver but what makes them be able reach those limits? How do they usually train and what is to be kept into account? Here is an outline of the typical training components that are crucial for Formula 1 drivers:

  1. Cardiovascular Fitness: Formula 1 drivers require exceptional cardiovascular endurance to sustain high heart rates during races. Activities such as running, cycling, and swimming are common for improving cardiovascular fitness.
  2. Strength Training: Building overall body strength is essential for withstanding the physical demands of racing. This includes exercises that target the core, neck, upper body, and lower body muscles. Strength training helps drivers maintain stability, endure high G-forces, and control the car effectively.
  3. Neck Strength: Formula 1 drivers experience significant strain on their neck muscles due to the forces acting on their heads during rapid accelerations, decelerations, and turns. Neck exercises, such as isometric training and weighted neck movements, are typically incorporated to enhance neck strength and stability.
  4. Flexibility and Mobility: Maintaining flexibility and mobility is vital for drivers to maneuver their bodies within the tight cockpit and react quickly to changing driving conditions. Stretching exercises, yoga, and Pilates can improve flexibility and overall body control.
  5. Reaction and Coordination: Formula 1 drivers must have exceptional hand-eye coordination, reaction time, and spatial awareness. Various drills and exercises, including reaction training, hand-eye coordination exercises, and simulator sessions, are commonly used to enhance these skills.
  6. Endurance Training: Long-duration activities, such as cycling or long-distance running, help drivers develop muscular endurance, mental stamina, and the ability to maintain focus over extended periods.

Behind every successful Formula 1 driver is a dedicated training team that plays a pivotal role in optimizing performance. These teams, consisting of fitness trainers, physiotherapists, and sports scientists, work closely with drivers to design individualized training programs, monitor progress, and fine-tune performance. Their expertise in biomechanics, nutrition, and recovery techniques ensures that drivers are physically prepared to tackle the challenges of each race.

Conclusions

The world of Formula 1 is a captivating spectacle that pushes the limits of human performance. The demanding nature of the sport requires Formula 1 drivers to possess exceptional physical capabilities, including speed, agility, and endurance. The anatomy of a Formula 1 driver plays a crucial role in their ability to excel on the track.

When it comes to the specific muscles used in a Formula 1 race, several key muscle groups come into play. The neck muscles provide stability and support during high-speed turns, while the forearm and hand muscles are constantly active as drivers grip the steering wheel. The core muscles provide stability to the driver’s torso, and the leg muscles are engaged during braking and acceleration. The gluteal muscles assist in stabilising the hips, and the cardiovascular system ensures endurance and performance.

Orientation in Anatomy

Photo by Olenka Kotyk on Unsplash

In anatomy, kinesiotherapy, biomechanics and other disciplines that involve human movement and orientation the knowledge of the anatomical planes, axes and general orientation data is crucial to properly describe the correct motions and locations. Not only medical professionals but also health instructors and wellness and fitness users are benefiting from knowing these details.  

Our approach is diving these details in 3 categories:

  • Anatomical Planes/Cardinal Planes
  • Anatomical Axes 
  • General Orientation Data

What are exactly Anatomical planes?

Anatomical planes are imaginary lines used to divide the human body into different sections or regions for the purpose of describing the location and relationships of structures within the body. 

There are three main anatomical planes: 

  • Sagittal or Longitudinal plane – separating the left and right sides of the body. (Fig. 1-2)
  • Frontal or Coronal plane – separating the front (anterior) and back (posterior) of the body. (Fig.3-4)
  • Transverse or Axial plane – separating the body in the upper (superior) and  the lower (inferior) part. (Fig.5-6)
Fig.1

Fig. 1 – The Sagittal plane

Fig. 2 – The Sagittal plane with additional general orientation data

Fig. 3 – The Frontal plane

Fig. 4 – The Frontal plane with additional general orientation data

Fig. 5 – The Transverse plane

Fig. 6 – The Transverse plane with additional general orientation data

On top of the biomechanical data, these planes are also used in medical imaging, surgical procedures, and other aspects of healthcare to help clinicians accurately describe the position and relationship of structures within the body.

Anatomical planes are correlated with anatomical axes that are used to describe the rotation of a limb of a body part. When describing anatomical motion, the anatomical planes describe the axis along which an action is performed. For example, by moving through the transverse plane, movement travels from head to toe. For example, if a person jumped directly up and then down, their body would be moving through the transverse plane in the coronal and sagittal planes.

What are the main Anatomical Axes?

Similar to anatomical planes, anatomical axes are imaginary lines that run through the body and are used as a reference point for describing movement or orientation of body parts. The three main anatomical axes are:

  • The Transverse or Horizontal axis (Fig. 7). The transverse axis runs horizontally from left to right.
  • The Anteroposterior(AP) or Sagittal axis (Fig. 8). The AP Axis passes through the body or a body part from the anterior (front) to the posterior (back).
  • The Longitudinal /Vertical Axis/ Superior – Inferior /Cephalocaudal/Cranio-Caudal axis (Fig.9) The longitudinal axis runs lengthwise through the body or any of its parts, it runs from the head (cranial end) to the tailbone (caudal end).

Fig. 7 – The Transverse axis

Fig. 8 – The Anteroposterior axis

Fig. 9 – The Longitudinal axis

These axes are important in anatomy and biomechanics because they help describe movements and positions of the body. For example, if you were performing a bicep curl, the sagittal axis would be the axis around which your elbow joint is rotating. The frontal axis would be the axis around which your shoulder joint is rotating, and the vertical axis would be the axis that runs through your body from top to bottom. The frontal axis, also known as the coronal axis, runs from side to side, passing through the body at the level of the ears, and divides the body into front (anterior) and back (posterior) portions. 

By understanding these axes and how they relate to movement, we can better understand the mechanics of the human body.

Each axis is perpendicular to one anatomical plane like:

  • The Longitudinal axis is perpendicular on the Transverse plane
  • The Transverse axis is perpendicular on the Sagittal plane and
  • The Anteroposterior axis is perpendicular on the Frontal plane.

What is General Orientation data?

In biomechanics, orientation data is often used to describe the relative position of body segments or joints during movement. The terms lateral, medial, anterior, posterior, proximal, distal, caudal, and cranial are used to describe orientation data.

Lateral refers to the side of the body that is farther away from the midline, while medial refers to the side that is closer to the midline. For example, when a person is standing upright, their arms are positioned laterally to their torso, while their legs are positioned medially to their arms. (Fig 10)

Fig. 10 – The Lateral/Medial Orientation

Cranial refers to the direction that runs from the head end of the body towards the tail, while Caudal refers to the direction that runs from the tail end of the body towards the head. For example, when a person performs a backbend, their spine moves in the cranial direction, while their legs move in the caudal direction. (Fig.11)

Fig. 11 – The Cranial/Caudal Orientation

Anterior refers to the front of the body, while posterior refers to the back of the body. For example, when a person performs a push-up, their chest moves in the anterior direction, while their back moves in the posterior direction. (Fig. 12,13)

Fig. 12 – The Anterior/Posterior Orientation and the Anteroposterior Axis

Fig. 13 – The Anterior/Posterior Orientation

Proximal refers to a structure that is closer to the center of the body or to another specified structure, while distal refers to a structure that is farther away from the center of the body or from another specified structure. (Fig.14)

For example, in the upper extremity, the shoulder joint is considered proximal to the elbow joint because it is closer to the center of the body. Conversely, the hand is considered distal to the elbow joint because it is farther away from the center of the body.

Similarly, in the lower extremity, the hip joint is considered proximal to the knee joint because it is closer to the center of the body. The foot, on the other hand, is considered distal to the knee joint because it is farther away from the center of the body.

Fig. 14 – The Proximal/Distal Orientation

By using the general orientation data terms, researchers and practitioners can more precisely describe the movements and positions of the body during various activities, such as sports or rehabilitation exercises. This information can then be used to evaluate the effectiveness of different exercises or techniques, identify areas of weakness or injury, and design interventions to improve performance or prevent injury.

Key Takeaways

Knowledge of anatomical planes, axes, and general orientation data is crucial for accurately describing the human body’s motions and locations. These concepts are used not only by medical professionals but also by health instructors, fitness users, and in medical imaging, surgical procedures, and other aspects of healthcare. Anatomical planes are imaginary lines that divide the human body into different sections, and there are three main anatomical planes: sagittal, frontal, and transverse. Anatomical axes are imaginary lines used as a reference point for describing the movement or orientation of body parts, and the three main anatomical axes are the transverse, anteroposterior, and longitudinal axes. General orientation data terms, such as lateral, medial, anterior, posterior, proximal, and distal, are used to describe the relative position of body segments or joints during movement.

Conclusions

Overall, anatomical planes, axes and orientation data play a crucial role in the study of anatomy and medicine. By providing a standardised and universal system for describing the location and relationships of structures within the body, these concepts are essential for accurate diagnosis, treatment planning, and communication among medical professionals or healthcare and wellness providers.

How To Do Sprint Retrospectives Easy #2

Photo by Parabol | The Agile Meeting Toolbox on Unsplash

Reading time: 7 mins

A few days ago we went over the first part of “How to make sprint retrospectives easy” and today we are continuing on the subject. We will give more details about how to properly get feedback and how to set owners to the newly identified problems your team has surfaced. Nothing is easy but practice makes perfect and this small guide will make your life easier on how to tackle sensible situations while making progress.

Prepare your data

  • You have a list of problems that people care about
  • You have a list of possible solutions, no matter how feasible they are
  • Your team had time to think it through, so things might change

Create an excel file (or Google sheet):

  • List of issues that you want to fix (“Problems”) and try to group them in 3-5 “areas”. These will be your “pillars”
  • Give them name codes. That always helps, unless it doesn’t. A lot of people don’t really like namecodes, but are good with colors. Have a different color for each pillar.
  • Organize your actions for each PIllar
  • Make sure you didn’t miss anything and set up a Retrospective follow up meeting

You can take it one pillar at a time or all together, depending on how the team is feeling. If people get tired, break. Pizza helps in the start of these meetings to calm spirits and start constructive conversations.

Low hanging apples

Review actions for each pillar, add new stuff, modify existing ones 10-15 mins.

Now let’s see what can be done relatively quickly and with little effort. Put those on top of the action list and add owners against them. Should be done by EOD, right?

Fourth (hidden) rule: You shouldn’t be owning the actions. You’re accountable but not responsible. You’re driving the process, not loading the truck. Yes you could have one or two. Or help your colleagues out, but just don’t have your name against half the list.

Fifth rule: Always an owner (not 5) Always an ETA. IF not an ETA, an ETA for the ETA.

Other fields:

  • Priority: good, not mandatory
  • Impact: important when you report to others outside the team

Your table will look like this

Feedback ItemAction Key ActionStatusETAOwnerPriorityImpactComments

The real deal

Tough part starts now. You’ll likely have actions that require other parties to be involved to help or even divine intervention. Don’t panic! Take them one by one, assess the impact and also add the feasibility of the solution.

Likely people will start to complain, you’ll might hear things like:

  • We’ve done this x times and it didn’t work
  • This is always like that around here
  • Don’t even think of starting that conversation with them!
  • They are the ones that stay in the path of greatness
  • They are always like that
  • They something something

That’s when you need to steer the conversation to:

  • That was then this is now
  • Who are “they”? Let’s engage “them” to explain the impact. So add an action on the list with an Owner and ETA.

Oh, and there are the “impossible” things that you might find on the list

  • Add Owners and ETA
  • Find out why they are not feasible

And now it’s time for another

Break

Breaks are good, people think about things, they get to talk and come up with creative ways of dealing with things. Breaks are good.

What have you achieved

  • You have a list of Feedback items grouped in Pillars
  • You have a list of clear actions for each Pillar with Owners and ETA
  • You have a new thing that you need to drive and it will take time

This is it for today, if missed the first part of “How to make sprint retrospectives easy”, here you can find it.

I hope you enjoyed today’s article, please give us a thumbs up if you did and let us know what other Software Development subjects might interest you.

See you around.

Post Stroke Recovery and Examples of Dedicated Rehabilitation Devices

Photo by Jon Tyson on Unsplash

Last week we discussed VR and AR and their potential usage in healthcare and today we are going to dive more into a more specialized subject: Post stroke recovery and examples of dedicated rehabilitation devices. The following sections review a few  solutions used in rehabilitation of stroke survivors helping them recover their neuromotor deficiencies.

MOTIVATION

Every two seconds someone somewhere in the world is having a stroke and every 10 seconds a life is claimed where 80% of all the people that suffered a stroke are from low and mid-income countries. Stroke survivors often remain incapacitated due to the lack of oxygen and nutrients for the affected brain area.  An obstruction that lasts even a few minutes can damage the neurons and therefore they die.  The functions that were handled by these neurons are affected and the neuromotor disabilities have the biggest incidence.  Thanks to the neuroplasticity of the brain the functions that were executed by the affected neurons can be relearned and their function can be taken over by other healthy neurons from vicinity.

Neuromotor disabilities can significantly affect a person’s life, especially the activities of daily living (ADL) like eating or washing. This can downgrade one’s quality of life as the rehabilitation process is focused on long term kinesiotherapy.

The kineto-therapeutic support (classical therapy) is limited due to two factors: the long-time sessions (up to 5 hours per day) and the growing number of affected persons. The number of specialized personnel is not growing at the same pace and as a result fewer rehabilitation sessions can be applied to each patient.

The Simulation hypothesis indicates that to relearn a particular movement one has to visualize the movement either on its own or as an observation due to the strong connection between the motor and cognitive brain mechanisms. Basically, the patient can start the rehabilitation very early even if he or she just observes certain movements as an example to someone else. 

Moving forward we go over a list of rehabilitation devices and they contain complex technologies such as FES (Functional Electrical Stimulation) and robotics. The review is continued with an analysis of the software solutions used in rehabilitation.

REHABILITATION DEVICES

In rehabilitation, there are a significant number of eLearning solutions that can be used complementary with the classical therapy, based on kinesiotherapy. The solutions contain complex technologies such as FES, NMES (Neuromuscular Electrical Stimulation), EMG (Electromyography), BCI and robotics.

Various products that target the patient’s rehabilitation are available on the market and  in this paper there is a detailed list with more than 100 devices used for upper limb rehabilitation. They are classified based on the following criteria:

a. The joint system they support.

b. The device’s DOF (Degree of Freedom). This is represented by a sum of all independent movements performed by the joints of the device.

c.  The supported movements types, such as: adduction/abduction, flexion/extension, pronation/supination, grip and release, horizontal and vertical displacement, etc. Also, the movements can be active or passive (with or without external help to execute a certain movement). 

d. The patient’s health condition as neuromotor rehabilitation solutions can be used for certain conditions such as: stroke, cerebral palsy, essential tremor, multiple sclerosis, primal cord injuries and traumatic brain injury.

In the following, a few devices of interest are shortly described.

MusicGlove

MusicGlove is a rehabilitation device that aims to improve the hand function for stroke survivors and other neuromotor disabilities. The device is connected to a  computer that displays a music environment similar to the games. In the respective application the subjects should follow the musical notes that appear on the screen making certain moves.  These types of exercises are helping the subject improve the hand function after a neuromotor disability. The benefits of using MusicGlove devices are supported by a clinical study with patients who suffered a stroke.  In that study 12 patients were diagnosed with mild chronic hemiparesis. They were randomly selected to use the MusicGlove device at the same time with conventional therapy. Each selected patient used the device for 6 sessions of one-hour length, three times per week for 2 weeks. At the end of the study it was shown that the object grip movement of the selected subjects improved with a higher rate than traditional therapy.

MIT-Manus and InMotion ARM

The InMotion ARM device represents a clinical version of the MIT-Manus robot. In the overall description it is mentioned that its usage can establish an efficient, personalized therapy for patients with neuromotor disabilities. One of the reasons mentioned was because the device is based on intelligent, interactive technology which is able to adapt itself to each patient’s capacity. InMotion covers multiple rehabilitation solutions, such as:

a. For upper limbs: InMotion ARM Therapy System, InMotion WRIST Interactive Therapy System and InMotion HAND.

b. For lower limbs:  Anklebot InMotion ANKLE Exoskeletal Robot and InMotion Exoskeletal Arm Robot.

Armeo

This solution uses a virtual scenario incorporated with a gravitational compensation system for the therapy for upper extremities with self-initiated and functional treatment. The included exercises are provided into a game-like setup which helps the patients to improve their motor abilities and real-time performance through the augmented performance feedback. In a study that involved stroke patients with mild to severe hemiparesis, the patients manifested their preference for this rehabilitation solution versus the classical therapy. 

The gravity-supported arm exercises can improve arm movement ability with a brief 1:1 assistance from a therapist (~ 4 minutes per session). This solution contains a 3-dimensional weight support, instant visual movement feedback, simple game-like environment and the results of this type of therapy were noticed even at the 6 months follow-up check-up.

Four distinct products are included in the Armeo therapy concept: Armeo Power, Armeo Spring, Armeo Spring Pediatric and Armeo Boom and each of them are specially conceived for a certain stage of the recovery process, with one exception the Armeo Spring Pediatric which is designed to cover children rehabilitation cases.

Bi-Manu-Track

Bi-Manu-Track is a robotic device with 2 DOF designed for the wrist and forearm region and works on the principle of bilateral training. According to this paper, the device permits a DOF for the pronation and supination of the forearm. When utilized in vertical position the device permits a DOF for dorsiflexion/volar flexion of wrist. The device is connected to a visual display that shows the number of effectuated cycles and a computer that collects the data and controls the motors. Bi-Manu-Track can be used in 3 modes:

  • Passive, where the robot assists both upper limbs.
  • Active-Passive, where the movements are effectuated in mirror mode initiated by the less affected limb.
  • Active-Active, where both upper limbs initiate the movement.

Bi-Manu-Track impact was measured in a study where it was found that the greater number of repetitions and the bilateral approach could have positively impacted the upper limb motor control and power compared with other techniques based on ES (Electrical Stimulation).

PowerGrip

The PowerGrip device is an EPPO (Electric Powered Prehension Orthosis) that is helpful for picking up, grasping, holding and manipulating objects. PowerGrip uses switches or sEMG (surface electromyography) signals to control the input of the device. The newer versions use myoelectric sensors that are placed on one or two functional muscles.

REVIEW

Today we learned about 5 rehabilitation devices used in stroke recovery and their common elements like:

  1. The usage of an interactive virtual environment, as seen in the MusicGlove and Armeo case. However, in these cases the virtual environment is displayed on a computer monitor.
  2. The existence of personalized treatment related to a patient’s health condition for an appropriate recovery plan.
  3. The possibility to effectuate a high number of repetitions for a faster recovery

Also we learned about various limbs movements important in the neuromotor rehabilitation like: abduction, flexion/extension and pronation/supination. The initial prototypes of Corporis were covering this type of elements as well and multiple elements that are aiding in identifying and learning this type of movements are captured in the current versions of the Corporis application. In this regard Corporis contains  graphical elements for various orientation data like:

  • Axes: Longitudinal, anteroposterior and transverse axes
  • Cardinal Planes: Frontal, Transversal, Sagittal planes
  • Orientation terms like: Distal/Proximal, Medial/Lateral, Anterior/Posterior and Cranial/Caudal 

Check it out on Google Play to see more about them and to learn more about how to identify various orientation elements that are a base for neuromotor rehabilitation exercises.
