Summary
Brief summary (as posted)
This prospective, single-center, assessor-blinded, parallel-group randomized controlled trial investigated whether adding proximal motor control exercises (PMCE) to conventional physiotherapy treatment (CPT) improved shoulder function and scapular muscle activation in women with post-mastectomy shoulder dysfunction. Women aged 35-55 years were randomly allocated to receive either PMCE plus CPT or CPT alone. Both groups attended supervised physiotherapy sessions three times weekly for 6 weeks. Outcomes were assessed at baseline, immediately after treatment, and at 12-week follow-up. The primary outcome was scapular and shoulder muscle activation assessed using surface electromyography (SEMG), while secondary outcomes included shoulder pain and disability assessed using the Shoulder Pain and Disability Index (SPADI).

- description
- Surface electromyography (sEMG) was used to assess the activation patterns of the serratus anterior, upper and lower trapezius, supraspinatus, and infraspinatus muscles during arm elevation. The sEMG assessment was conducted using a wireless sEMG system with a sampling rate of 2000 Hz and a bandwidth of 20-500 Hz. Pre-gelled, disposable, self-adhesive Ag/AgCl electrodes were placed over the muscle bellies according to the SENIAM recommendations, with an inter-electrode distance of 20 mm.
