Walk to think

Exercise improves learning on 3 levels: first, it optimizes your mind-set to improve alertness, attention and motivation; second, it prepares and encourages nerve cells to bind to one another, which is the cellular basis for logging in new information; and third, exercise spurs the development of new cells from stem cells.


Children solve problems better after exercising. Those, whose brain is alert "as during exercise" do cognitive tasks better even without exercising.

Error-induced post-stroke walking training

Error-induced treatment on a split treadmill leads to longer-term improvements in gait deficits poststroke, as was tested 3 months after the training. The error augmentation strategy, which promotes stride-by-stride adjustment to reduce asymmetry and results in improved asymmetry during overground walking practice, appears to be critical for obtaining the improvements observed.

Training to walk amid uncertainty with Re-Step: measurements and changes with perturbation training for hemiparesis and cerebral palsy.

Motivation for PT

From a discussion on ResearchGate:

"Exercise Motivation Inventory (Markland & Hardy, 1993) to measure motivation in an exercising environment. Although NOT specific to "rehab" per se, it may be suit your needs."

"The short form Patient Activation Measure (PAM) is a 13-item instrument that assesses patient self-reported knowledge, skills and confidence for self-management of one’s health or chronic condition. It divides consumers and patients into one of four progressively higher activation levels that are associated with specific self-care and other health related behaviours."





 

Kinect for rehabilitation

Recently many labs tried to implement Kinect sensing device of Microsoft for rehabilitation in one or another way. 

Recently the West Health Institute announced that it has developed the Reflexion Rehabilitative Measurement Tool uses the Kinect technology to not only monitor adherence to a rehab program, but to also track the motions of rehabilitative exercises to ensure that they are done correctly and to measure progress.

Parkinson’s disease is testable with Wii board

The Wii Balance Board is a balance board accessory for the Wii video game console.

Recently, the validity of the Nintendo Wii balance board as a measurement tool for the assessment of postural stability in individuals with Parkinson’s (Clin Rehabil). Obviously, it can be used as a testing tool for other conditions. Today the Wii board is more and more common tool in rehab facilities for motor training.

Another implementation of the board was attempted for gaming purposed, when the sensors of the board were combined with regular shoes. The resulted instrumented shoes could be used as a game controller. The prototype can potentially be used as a measurement tool.


Similar scheme is used in Re-Step™ shoes, but with more sensors per shoe and sophisticated software for the analysis of walking by conventional and non-linear methods.    

Exercising in stroke clubs enhances mobility

Exercising in stroke clubs during 12 months improved gate parameters (walking speed and distance), but the decrease in falls incidence was not significant.

Chaotic perturbations to avoid falls in elderly - SMILING

Researchers in Europe continue the good fight against age-related impairments and in favour of social inclusion. Experts from the SMILING ('Self mobility improvement in the elderly by counteracting falls') project, initiated by Step of Mind ltd, focused on prevention of falls by training the elderly to walk on uneven ground while carrying out another activity. The result? A pair of computer-controlled shoes that simulate changes in the height and slope of the ground beneath a user's feet during active walking.

CP before is was CP

Deformations have been attributed to supernatural causes since antiquity. Cerebral palsy was associated with God's wrath, witchcraft, the evil eye, or maternal imagination. Greek scholars recommended prevention by tight swaddling, a custom that persisted into modern times. In the Middle Ages, the midwife's negligence was held responsible as was difficult teething. Morgagni described in 1769 that the neonatal brain can liquefy, and Bednar described leukomalacia in 1850 as a distinct disorder of the newborn. In 1861, Little associated cerebral palsies with difficult or protracted labor and neonatal asphyxia, but he was challenged by Freud, who in 1897 declared that most cases are prenatal in origin. In 1868, Virchow demonstrated inflammatory changes, a view recently confirmed by Leviton and Nelson. Although a causal relationship of cerebral palsy to the birth never has been established, the habit to put the blame for cerebral palsy on someone remained a frequent attitude.

Wrist vibration improves arm movements

Effects of Wrist Tendon Vibration on Targeted Upper-Arm Movements in Poststroke Hemiparesis
Megan O. Conrad, Robert A. Scheidt, Brian D. Schmit
Abstract
Background. Impaired motor control of the upper extremity after stroke may be related to lost sensory, motor, and integrative functions of the brain. Artificial activation of sensory afferents might improve control of movement by adding excitatory drive to sensorimotor control structures. The authors evaluated the effect of wrist tendon vibration (TV) on paretic upper-arm stability during point-to-point planar movements. Methods. TV (70 Hz) was applied to the forearm wrist musculature of 10 hemiparetic stroke patients as they made center-out planar arm movements. End-point stability, muscle activity, and grip pressure were compared as patients stabilized at the target position for trials completed before, during, and after the application of the vibratory stimulus. Results. Prior to vibration, hand position fluctuated as participants attempted to maintain the hand at the target after movement termination. TV improved arm stability, as evidenced by decreased magnitude of hand tangential velocity at the target. Improved stability was accompanied by a decrease in muscle activity throughout the arm as well as a mean decrease in grip pressure. Conclusions. These results suggest that vibratory stimulation of the distal wrist musculature enhances stability of the proximal arm and can be studied further as a mode for improving end-point stability during reaching in hemiparetic patients.

Stroke statistics - cost and recovery

Total cost of stroke to the United States: estimated at about $43 billion per year
Direct costs for medical care and therapy: estimated at about $28 billion per year
Indirect costs from lost productivity and other factors: estimated at about $15 billion per year
Average cost of care for a patient up to 90 days after a stroke: $15,000
For 10 percent of patients, cost of care for the first 90 days after a stroke: $35,000

Percentage of direct cost of care for the first 90 days:
Initial hospitalization = 43 percent
Rehabilitation = 16 percent
Physician costs = 14 percent
Hospital readmission = 14 percent
Medications and other expenses = 13 percent.

The Effects of a Stroke (from the National Stroke Association):

10 percent of stroke survivors recover almost completely
25 percent recover with minor impairments
40 percent experience moderate to severe impairments that require special care
10 percent require care in a nursing home or other long-term facility
15 percent die shortly after the stroke.

In addition, approximately 14 percent of stroke survivors experience a second stroke in the first year following a stroke.

No limit to brain plasticity

The right hemisphere of the girl’s brain stopped developing early in the womb and the developing optic nerves reached the optic chiasma, the nerve was drawn to the left.

Scientists have discovered how a 10-year-old girl born with half a brain is able to see normally through one eye. The youngster, from Germany, has both fields of vision in one eye and is the only known case of its kind in the world.

University of Glasgow researchers used Functional Magnetic Resonance Imaging (fMRI) to reveal how the girl’s brain had rewired itself in order to process information from the right and left visual fields in spite of her not having a whole brain. The right hemisphere in the girl’s brain failed to develop in the womb.

Normally, the left and right fields of vision are processed and mapped by opposite sides of the brain, but scans on the German girl showed that retinal nerve fibres that should go to the right hemisphere of the brain diverted to the left.

Further, the researchers found that within the visual cortex of the left hemisphere, which creates an internal map of the right field of vision, ‘islands’ had been formed within it to specifically deal with, and map out, the left visual field in the absence of the right hemisphere.

Dr Lars Muckli of the Centre for Cognitive Neuroimaging in the Department of Psychology, who led the study, said: “This study has revealed the surprising flexibility of the brain when it comes to self-organising mechanisms for forming visual maps.

“The brain has amazing plasticity but we were quite astonished to see just how well the single hemisphere of the brain in this girl has adapted to compensate for the missing half.

"Despite lacking one hemisphere, the girl has normal psychological function and is perfectly capable of living a normal and fulfilling life. She is witty, charming and intelligent."

The girl’s underdeveloped brain was discovered when, aged three, she underwent an MRI scan after suffering seizures of brief involuntary twitching on her left side.

Apart from the seizures, which were successfully treated and slight weakness on her left side (hemiparesis), the girl had a normal developmental and medical history, attending regular school and taking part in activities such as roller-skating.

In other cases, where patients have half of the brain removed (hemispherectomy), to treat severe epilepsy for example, one field of vision is lost in both eyes – i.e. they see only objects on the left or right side of their vision. In the case of the German girl, her left and right field vision is almost perfect in one eye.

Visual information is gathered by the retina at the back of the eye and images are inverted when they pass through the lens of the pupil so that images in your left field of vision are received on the right side of the retina, and images from the right are received on the left. The part of the retina closest to your nose is called the nasal retina, while the other half is called the temporal retina, as it is next to the temples of the head, and both halves have separate nerve fibres which transmit the information received.

Normally, the nerve fibres from the nasal retina cross over in a part of the brain called the optic chiasma and are processed by the hemisphere on the opposite side. The nerve fibres from the temporal retina remain in the same hemisphere, so this means that the left and right visual fields at processed by opposite sides of the brain.

However, in this case, the nasal retinal nerve had connected to the left brain hemisphere.

The scientists believe the right hemisphere of the girl’s brain stopped developing early in the womb and that when the developing optic nerves reached the optic chiasma, the chemical cues that would normally guide the left eye nasal retinal nerve to the right hemisphere were no longer present and so the nerve was drawn to the left.

This implies that there are no molecular repressors to prevent nasal retinal nerve fibres from entering the same hemisphere.

Dr Muckli added: “If we could understand the powerful algorithms the brain uses to rewire itself and extract those algorithms together with the general algorithms that the brain uses to process information, they could be applied to computers and could result in a huge advance in artificial intelligence.”

The study, which was begun by Dr Muckli at the Max Planck Institute for Brain Research in Germany and involved colleagues at the Institute of Medical Psychology at Goethe-University, Frankfurt-am-Main, is published in the ‘Proceedings of the National Academy of Science USA’.

TBI: designed for young children

engraving

A year ago a post about traumatic brain injury TBI statistics in children was published. Occasionally, yesterday I saw pictures from The Book of Accidents: designed for young children. It was published in 1831. This masterpiece is illustrated by numerous possibilities to be killed of severely injured. I believe that little readers were impressed for the entire life. As far as most of the engravings demonstrate other 'young children' causing traumas to their friends on purpose, some readers could definitely use the knowledge acquired from the book for causing accidents and not for avoiding them.

Many illustrations are related to TBI, following disability, motor disorders, and, possibly, rehabilitation.

Tricycle for disabled children

The need of a tricycle for disabled children that are able to cycle is permanent. Several commercially available models are not comfortable, awkward, and non-ergonomic. The devise is to be safe, easy to climb and to get off, ergonomic, and designed for children.

Shabtai Hirshberg from School of Practical Engineering at Hadassah College Jerusalem designed this trike to encourage physical activity among kids suffering from neurological or muscular disorders. It is named A2B. When a child mounts the trike, stepping on the pedal locks the wheels, enabling the child to literally walk right into a seated position. The chest support keeps the child stabilized, and the whole trike can be customized to each child's needs.The gear based rear wheel makes it easy for the child to pedal since less force is required to drive the system. The entire steering shaft is cable driven so very small movements translate into larger ones.  

Now, I hope that Israel, known for its fast commercial implementation and economic stability (I mean the last weeks) will provide entrepreneurs for mass production  of the A2B.

Strength® Shoe

Science and technology do not stand still. To a broad collection, that included also SoM-ToUR, we can add Strength® Shoe (on the picture).
As far as I can understand the explanations, the summary of the idea is to train while stepping on calves only. Like ladies do, when walk on high heels. Like ladies do, when their high heels are broken.
Reasonable explanations why it is good and a list of about a hundred of sportsmen and tens of commands that train wearing Strength® Shoe may be found on the company site.
Releasing my imagination, I could suppose that high heels of my wife would "increase her anaerobic capacity and your anaerobic power by 500%" (update: in case they will be broken). The second though was much wiser: 'She has several pairs of high heels, each for less than "$129.95 only!"!'
