Assessment

Primary outcomes

Capillary Blood Flow Velocity: comparison of active point stimulation and sham stimulation (no stimulation) in the middle fingertip, 11-minute measurement (1-minute rest, 10-minute intervention)

Key secondary outcomes

Standing forward flexion distance (cm): comparison of active point stimulation and sham stimulation (no stimulation) in the middle fingertip, assessed after the test.

Shoulder muscle stiffness: comparison of active point stimulation and sham stimulation (no stimulation) in the middle fingertip, assessed before and after the intervention (before the standing forward flexion test).

Subjective evaluation of ease of movement (questionnaire): comparison of active point stimulation and sham stimulation (no stimulation) in the middle fingertip, assessed after the test.
