BIT (Bilateral Isokinematic Training)

BIT stands for Bilateral Isokinematic Training and my wife (who is a stroke sufferer) is currently undergoing this training by a trained Occupational Therapist. I did some personal research into this so call ‘New Technology’ or should I say ‘New Approach’ to treat people with unilateral (one side) damaged to the brain due to stroke or accidents etc.

Many studies and research are being done now to study the effects of this form of treatment and honestly, it is so technical that it is difficult for me to explain this in layman terms! I am sure you have noticed how babies when they kick, they often use both legs! This is what the doctors call our human inherent natural body Symmetrical Motion with respect to the mid-sagittal plane! Such studies comes under Neuro-Physiology.

In simple terms, BIT is being introduced into Stroke Recovery Programmes for upper body limbs training and there are contradicting research results from the medical practitioners. Some said BIT do not contribute significant improvements as compared to Unilateral training and others strongly recorded significant improvements! I went through the research papers and the test results are dependent on selected patient samples, extent of damaged, age factor etc. All I can say is that there are more proponents who observed positive improvements than negative ones.

In my wife’s case, she is on this program for about 2 months now and we noticed a marked improvement in the sense that her muscles are stronger thus her upper limb movements improved! I am doing a video on her typical routine which I hope that I can post it here for the benefit our readers.

One popular technique is the use of ‘Mirror Imaging’. What happens is that the affected hand is placed inside a box where on the out-side of the box is a mirror! When the patient is told to move her good hand, she sees the reflection of the good hand on the mirror giving the impression that the affected hand is moving! However I noticed that although my wife raised her right wrist, the good side, her affected left hand moves accordingly! What she sees is just the mirror reflection and she cannot see her own left hand because it is in the box!

Well that much for BIT and there are many other techniques used in her session but always using both hands (Bilateral) rather than just exercising the affected hand (Unilateral) to move which is the normal Psyhio Training. Guess that’s all for BIT and do be look out for the videos in my coming posts. The filming is schedule on the 27th May.

    Hi there,

    as an occupational therapy student,I found that this technique is effective as Ive seen myself the improvement in most of my patients/
    In my opinion, I prefer to use this technique rather than unilateral training is because patient (mostly stroke patients) tend to compensate the affected hand movement with their body. You know how it looks like when stroke patient with hemiparesis trying to lift his hand, naturally his upper body tend to follow and compensate the movement.

    Im graduating next year, definitely going to stick to this approach.
