Protocol summary

Study aim
Impact of 8‑Week Mius Muscle Training on Upper‑Limb Surface EMG and Grip Strength in Pianists
Design
Two arm parallel group outcome assessment
Settings and conduct
The study was conducted under the supervision of the University of Isfahan.
Participants/Inclusion and exclusion criteria
At least six months of continuous piano playing experience. Ability to perform staccato technique. No upper-limb musculoskeletal injury in the past six months Exclusion criteria: Absence from more than two training sessions. Acute injury occurring during the study. Voluntary withdrawal from participation.
Intervention groups
مطمئناً — نسخه کوتاه‌تر و فشرده‌تر برای بخش روش‌ها: The eight-week Mius Muscle program comprised two supervised 90‑minute group sessions per week. Week 1 introduced upper‑limb anatomy and weight transfer, emphasizing body awareness and spinal alignment. Week 2 targeted shoulder‑girdle release via rotary movements, elevation, and scapular circles. Week 3 addressed wrist and finger release using three‑level scapulo‑thoracic exercises and movements to improve weight transfer. Week 4 emphasized energy control with fine motor drills to enhance neuromuscular coordination. Week 5 focused on spasm reduction and energy transmission. Week 6 integrated exercises from weeks 2–5, emphasizing wrist and MCP mobility. Week 7 reinforced focused attention to boost neuromuscular coordination. Week 8 consolidated gains with exercises to relieve mental and muscular fatigue. می‌خواهید باز هم خلاصه‌تر شود تا مناسب بخش یک جمله‌ای یا تیتر روش‌ها شود؟
