Abstract

The results showed that the range of motion (ROM) was improved in 6 out of 7 cases, while fine movement of the hand was also improved in 4 cases. These improvements were observed a few days after the initiation of whole-hand electrical neural stimulation. In one chronic stroke case, the treatment resulted in an almost full recovery of hand control during the first 30 minutes of sub-threshold sensory stimulation, including pinching and grasping. This dramatic recovery led the authors to hypothesize that the responder would show no lesioning of the motor cortex on CT or MRI images. While more cases are needed to test the limitations of this modality and to determine the relationship between the level of recovery and the topology of CNS lesioning, this work illustrates the utility of this approach for improving motor control of the hand in chronic stroke patients.

Ii. Materials And Methods

Seven patients with no severe muscle atrophy were given whole-hand electrical stimulation. Patient ages ranged from 11 to 65 years old. Post-onset duration was between 3 and 44 months. All cases suffered from spastic hemiparesis or poor hand control that did not show marked improvement with a routine rehabilitation program. Patients with cardiac pacing or epilepsy were not included (Table 1).
