Effectiveness of low-level laser therapy and Kinesio taping in the rehabilitation of supraspinatus tendinitis: A case report

Supraspinatus tendinitis is a common overuse injury in athletes engaged in repetitive overhead activities, such as badminton. It often results in pain, reduced range of motion (ROM), and impaired performance. Low-level laser therapy (LLLT) and Kinesio taping (KT) are emerging physiotherapeutic modalities reported to reduce inflammation, promote tendon healing, and improve neuromuscular control. However, their combined application in acute supraspinatus tendinitis remains underexplored. A 19-year-old male badminton player presented with persistent right shoulder pain, weakness, and scapular dyskinesia following overhead training. Clinical examination revealed a painful arc, positive Hawkins–Kennedy and Neer’s tests, supraspinatus weakness (Grade 2/5), and limited abduction (80°). Imaging confirmed supraspinatus tendinopathy. Baseline outcome measures included a Visual Analog Scale (VAS) score of 9, shoulder pain and disability index (SPADI) of 72%, and restricted abduction range. A progressive 4-week rehabilitation protocol was implemented, combining LLLT (810–904 nm, three sessions/week), KT, manual therapy, and exercise-based rehabilitation. Interventions were phasewise, progressing from pain relief and a gentle ROM to eccentric strengthening, proprioceptive neuromuscular facilitation, and plyometric sport-specific drills. KT was applied in both Y-strip and mechanical correction techniques to provide proprioceptive input and scapular alignment. The patient demonstrated significant improvement. Pain intensity (VAS) reduced from 9 to 0 by week 3, SPADI improved from 72% to 15%, and shoulder abduction increased from 80° to 170°. Muscle strength improved, with the supraspinatus rising from Grade 2/5 to Grade 4/5. Scapular rhythm normalized, proprioception improved, and the athlete successfully reintegrated into modified sport-specific training without fear of reinjury. This case demonstrates that the combined application of LLLT, KT, and structured physiotherapeutic rehabilitation can effectively reduce pain, restore function, and optimize biomechanics in supraspinatus tendinitis. A multimodal, stagewise approach targeting both inflammatory and neuromuscular deficits may enhance recovery and facilitate safe return to play in overhead athletes. Future studies should investigate long-term outcomes and optimal treatment parameters.
