Effect of Graded Motor Imagery in Impingement

Purpose: This randomized controlled trial aims to investigate the effects of Graded Motor Imagery (GMI) added to conventional physiotherapy in patients with Grade-2 shoulder impingement syndrome. The primary objectives are to evaluate the impact of GMI on pain intensity, range of motion, kinesiophobia, joint position sense, and quality of life. The hypotheses tested are: H0: GMI combined with conventional therapy has no effect on the aforementioned outcomes. H1: GMI combined with conventional therapy significantly improves these outcomes. Methodology: The study will include 30 participants (15 control, 15 intervention) diagnosed with Grade-2 shoulder impingement, recruited from a tertiary hospital. Participants will be randomly allocated into two groups: Control Group: Receives 15 sessions of conventional physiotherapy (ultrasound, TENS, hotpack, and therapeutic exercises). Intervention Group: Receives conventional therapy plus GMI, which includes three phases: (1) lateralization training (identifying left/right limb images), (2) motor imagery (mental rehearsal of functional movements), and (3) mirror therapy (visual feedback via mirror). Outcome measures include pain (Visual Analog Scale), range of motion (digital goniometer), joint position sense (mobile app-based assessment), kinesiophobia (Tampa Scale), upper extremity function (DASH questionnaire), and quality of life (SF-36). Pre- and post-intervention evaluations will be conducted.
