Electromyographic Biofeedback Muscle Recovery Meniscectomy

"The players performed 10 work sessions with EMG-BF. Each session was divided into three phases: (a) three trials without receiving feedback, (b) between six and ten trials with feedback of electromyographic activity, (c) three trials without feedback. In each trial, isometric contractions of the vastus lateralis were performed.~During maximum effort isometric contraction, the software associated with the ProComp Infiniti biofeedback unit collects the amplitude, the mean and maximum electromyographic signal, and also the contraction and tightening times. The contrac-tion time comprises the interval between the start of the contraction and achievement of the desired muscle tension. The tightening time is the period in which the tension voluntarily reached is maintained. For this study, the maximum and mean elec-tromyographic activity values were considered, calculated during the muscle tension time and maintained during each trial."
