The effect of post-activation potentiation on neuromuscular activation of smashing technique during the recovery period of meniscal injuries in elite badminton players: non-negative matrix factorization-based muscle and time-frequency coherence

Neuromuscular electrical stimulation effectively optimizes muscle coordination patterns during smash execution in athletes recovering from meniscal injuries. It enhances activation of key muscle groups and multi-band neural coordination, representing an efficient rehabilitation strategy for neuromuscular control function optimization.
