About this trial

In this study, the effects of Transcutaneous Electrical Nerve Stimulation (TENS) and Neuromuscular Electrical Stimulation (TENS + NMES) applied in addition to TENS on pain, shoulder joint range of motion and upper extremity functions will be comparatively evaluated in stroke patients with hemiplegic shoulder pain. In this direction, in the study; The effectiveness of both treatment approaches on the severity of hemiplegic shoulder pain, their contribution to shoulder functionality and daily living activities will be examined; It will be investigated whether NMES application added to TENS provides an additional clinical benefit compared to TENS.

Treatments tested in this trial

TENS
Procedure/Surgery
Transcutaneous Electrical Nerve Stimulation (TENS) will be applied to reduce hemiplegic shoulder pain. The stimulation will be delivered to the hemiplegic shoulder region using appropriate electrode placement. TENS parameters, including frequency, pulse duration, and treatment duration, will be set according to standard clinical practice. Stimulation intensity will be adjusted to produce a clear but comfortable sensory perception without causing discomfort. TENS will be administered in addition to the standard stroke rehabilitation program.
NMES
Other intervention
Neuromuscular Electrical Stimulation (NMES) will be applied in addition to TENS to activate paretic muscle groups involved in shoulder stabilization. NMES will be delivered to target muscles in order to elicit visible muscle contractions. Stimulation parameters, including frequency, pulse duration, contraction-relaxation cycles, and total treatment time, will be determined in accordance with standard clinical practice and adjusted based on participant safety and tolerance. NMES will be provided as an adjunct to both TENS and the standard stroke rehabilitation program.

Trial outcomes

Primary outcomes

Visual Analog Scale

Pain intensity in the hemiplegic shoulder was assessed during passive shoulder range of motion. With the participant in the seated position, passive shoulder flexion, abduction, and external rotation were performed to the maximum tolerated range. Pain intensity was rated on a 0-10 Visual Analog Scale (VAS), where 0 indicates no pain and 10 indicates the worst pain imaginable. The highest VAS score recorded during the three shoulder movements was used for analysis.

Time frame
