HandTutor, ArmTutor, legTutor and 3DTutor used in addition to CIMT in Post Stroke Patients

In an article entitled “Neurophysiological and Behavioral Effects of tDCS Combined With Constraint-Induced Movement Therapy in Poststroke Patients” published in ” Neurorehabilitation & neural repair” (2011). , LUIGI TESIO the authors state that recovery of motor function after stroke may well depend on a balance of activity in the neural network involving the affected and the unaffected motor cortices.

The objective of this study was to assess whether transcranial direct current stimulation (tDCS) can increase the training induced recovery in motor function.


14 patients with chronic stroke (mean Fugl-Meyer Upper Extremity Motor Assessment of 29) were enrolled in a double-blind shamcontrolled study. The study was to investigate neurophysiological and behavioral effects of bihemispheric tDCS combined with constraint-induced movement therapy (CIMT).

Results. Patients in both of the groups showed gains in primary outcome measures including the Jebsen Taylor Hand Function Test, Handgrip Strength, Motor Activity Log Scale, and Fugl-Meyer Motor Score. However, gains were seen to be larger in the active tDCS group.

Conclusions. CIMT alone seems to be effective in modulating local excitability but not in removing the imbalance in transcallosal inhibition. Bihemispheric tDCS may therefore achieve this goal and offer greater functional recovery.

The HandTutor and its sister devices (ArmTutor, LegTutor and 3DTutor) have shown that they are effective in increasing hand and wrist movement for post stroke patients through the use of stimulating and challenging software games. Intensive isolated exercise practice is being used in addition to task specific practice to improve rehabilitation outcomes in stroke, head injury spinal cord  and CP patients. An improvement in movement abiliaty will allow the patient to better achieve functional tasks and improve quality of life.
