Background: Sensory amplitude electrical stimulation has been reported to induce changes in corticospinal excitability. The aim of this review is to evaluate the effects of sensory electrical stimulation on hand and arm function in stroke patients.
Methods: A literature search was undertaken to locate papers that used sensory electrical stimulation in stroke patients. The methodological quality of each study was assessed using the Physiotherapy Evidence Database (PEDro) score.
Results: Ten studies were considered suitable for inclusion in this review. Six of the 10 studies provided the PEDro score, with the mean (standard deviation) score being 5.7 (1.0). There were no adverse effects in any of the studies. In only one study, the patients with acute stroke were included. There was much study of patients with mild arm hemiparesis. Most studies reported that sensory electrical stimulation was delivered at 10 Hz with pulse duration of 1 millisecond for 2 hours at the paretic wrist (median and/or ulnar nerve). Five studies reported sensory stimulation should not be used in isolation, but rather in combination with task training, to improve arm and hand function.
Conclusions: Sensory electrical stimulation may improve hand and arm function if it combines with functional task training in patients with mild arm paresis but there are no studies with high methodological quality. In addition, it is uncertain whether sensory electrical stimulation would be of benefit for patients with severe paresis and be effective in the acute phase. Therefore, the results of this review remain inconclusive due to a lack of suitable randomized controlled trials.
