Efficacy of Sensory Electrical Stimulation Versus Alternating Electromyogram (EMG) On Functional Recovery Of Hand in Chronic Stroke Survivors :Randomized Controlled Trial

This study aims to find out which treatment works better for improving hand function in stroke patients: sensory electrical stimulation or alternating electromyogram (EMG) stimulation. Both methods use electrical stimulation to help patients regain hand movement, but they work in slightly different ways. The goal is to see if one method is more effective than the other in helping stroke survivors recover their hand abilities.

Inclusion Criteria:

• Chronic stroke patients were between 45 and 65 years old, with a duration of illness ranging from 6 to 18 months post-stroke. They exhibited upper extremity spasticity no greater than 1+ on the Modified Ashworth Scale. Patients were cooperative, as indicated by a Mini-Mental State Examination (MMSE) score of ≥ 24, and were capable of grasping and releasing at least one block in the Box and Block Test.

Exclusion Criteria:

• Hand function impairment caused by factors other than stroke, unstable health conditions such as cardiac dysfunction, end-stage renal failure, or uncontrolled diabetes, long-term use of medications that may affect motor or sensory excitability, contractures or restrictions in wrist joint range of motion, pre-existing musculoskeletal diseases significantly impacting physical function, and a history of Botulinum Toxin injection in the hand muscles.
