This study investigates the biomechanical forces and neuromuscular patterns involved in classical and electric guitar performance, with applications to injury prevention and rehabilitation protocols. Using motion capture technology, electromyography (EMG), and force-sensing resistors, data were collected from 45 professional guitarists over 18 months on a part-time basis. Results indicate that prolonged guitar practice induces characteristic strain patterns in the flexor digitorum superficialis and profundus muscles, with peak forces reaching 8.2±1.4 N in the fretting hand. We identified three primary risk factors for focal dystonia and repetitive strain injuries: excessive grip force (>12 N), inadequate rest intervals (25° dorsiflexion). Based on these findings, a biofeedback training system was developed that reduced injury incidence by 67% in a controlled intervention study. This research provides quantitative evidence for evidence-based practice guidelines and opens new avenues for adaptive instrument design.
