ClinConnect Summary

This study explores the effectiveness of sensory electrical nerve stimulation (SENS) in enhancing hand function among chronic stroke patients. Thirty participants were randomly divided into two groups:

Study Group (A): Received SENS combined with task-specific training.

Control Group (B): Received only task-specific training.

Assessment Methods:

Before and after the intervention, both groups underwent evaluations using:

Grip Dynamometer: To measure grip strength.

Pinch Dynamometer: To assess pinch strength.

Digital Goniometer: To determine wrist flexion and extension range of motion....

Eligibility criteria

• Inclusion Criteria:
• • Patients who have experienced their first-ever ischemic stroke in the carotid system domain.
• • Age range: 40 to 65 years old.
• • Duration of illness: 30 to 180 days since stroke onset.
• • Spasticity of the affected hand muscles (wrist flexors, finger flexors, and finger adductors) must be grade 1+ or less according to the Modified Ashworth Scale.
• • Hand dysfunction severity ranges from mild to severe, defined by a score of ≤ 4 on the Medical Research Council Scale.
• Exclusion Criteria:
• • Presence of a deformity in the paralytic upper limb before the stroke.
• • History of a lower motor neuron lesion in the impaired upper extremity (e.g., polyneuropathy) before the stroke.
• • Skin abrasions or ulcerations on the affected upper limb.
• • Unstable health conditions, including cardiac dysfunction, end-stage renal failure, unstable diabetes, or uncontrolled hypertension (\>190/110).
• • Presence of a pacemaker or other implanted electrically sensitive devices.
• • Significant orthopedic conditions or chronic pain syndromes.
• • Chronic use of medications that may influence motor or sensory excitability (e.g., anti-epileptic or antipsychotic drugs).
• • Pregnancy.
