چکیده
OBJECTIVE To compare 2 telerehabilitation training strategies, repetitive tracking movements versus repetitive simple movements, to promote brain reorganization and recovery of hand function. METHODS Twenty subjects with chronic stroke and 10 degrees of voluntary finger extension were randomly assigned to receive 1800 telerehabilitation trials over 2 weeks of either computerized tracking training (track group) with the affected finger and wrist involving temporospatial processing to achieve accuracy or movement training (move group) with no attention to accuracy. Following movement training, the move group crossed over to receive an additional 2 weeks of tracking training. Behavioral changes were measured with the Box and Block test, Jebsen Taylor test, and finger range of motion, along with a finger-tracking activation paradigm during fMRI. RESULTS The track group showed significant improvement in all 4 behavioral tests; the move group improved in the Box and Block and Jebsen Taylor tests. The improvement for the track group in the Box and Block and Jebsen Taylor tests did not surpass that for the move group. A consistent group pattern of brain reorganization was not evident. The move group, after crossing over, did not show further significant improvements. CONCLUSION Telerehabilitation may be effective in improving performance in subjects with chronic stroke. Tracking training with reinforcement to enhance learning, however, did not produce a clear advantage over the same amount of practice of random movements. Two weeks of training may be insufficient to demonstrate a behavioral advantage and associated brain reorganization.

Complex versus simple ankle movement training in stroke using telerehabilitation: a randomized controlled trial.
BACKGROUND Telerehabilitation allows rehabilitative training to continue remotely after discharge from acute care and can include complex tasks known to create rich conditions for neural change. OBJECTIVES The purposes of this study were: (1) to explore the feasibility of using telerehabilitation to improve ankle dorsiflexion during the swing phase of gait in people with stroke and (2) to com...
متن کاملDesign and Usability of a Home Telerehabilitation System to Train Hand Recovery Following Stroke
Current theories of stroke rehabilitation point toward paradigms of intense concentrated use of the afflicted limb as a means for motor program reorganization and partial function restoration. A home-based system for stroke rehabilitation that trains recovery of hand function by a treatment of concentrated movement was developed and tested. A wearable goniometer measured finger and wrist motion...

Hand movement recovery and cortical reorganization were studied in 10 subjects with chronic stroke using functional MRI (fMRI) before and after training with an intensive finger movement tracking programme. Subjects were assigned randomly to a treatment or control group. The treatment group received 18-20 sessions of finger tracking training using target waveforms under variable conditions. The...

Several approaches to rehabilitation of the hand following a stroke have emerged over the last two decades. These treatments, including repetitive task practice (RTP), robotically assisted rehabilitation and virtual rehabilitation activities, produce improvements in hand function but have yet to reinstate function to pre-stroke levels-which likely depends on developing the therapies to impact c...
