Persistent AMI may contribute to muscle weakness, altered gait, and poorer rehabilitation outcomes. Although several rehabilitation strategies have been proposed, no complementary intervention has consistently demonstrated strong evidence for improving AMI.\n\nThis prospective single-case experimental study aims to evaluate whether visual biofeedback based on surface electromyography (sEMG) improves quadriceps motor performance during standard rehabilitation. Each participant will complete eight standardized rehabilitation sessions, including four sessions with visual sEMG biofeedback and four sessions without visual feedback. The order of the two conditions will be randomized, allowing each participant to serve as his or her own control.\n\nThe primary objective is to determine whether visual sEMG biofeedback improves the accuracy of quadriceps contraction, assessed by the percentage deviation from a predefined target. Secondary objectives include evaluation of motor engagement, motor control, muscle activation, perceived exertion, and pain.\n\nBetween three and five adult patients presenting AMI after knee surgery will be included. Because recovery patterns are highly individualized, a Single-Case Experimental Design (SCED) with repeated within-subject measurements has been selected to characterize individual treatment responses while minimizing inter-individual variability",[83,84,85],"Arthrogenic Muscle Inhibition","Knee Injuries","Postoperative Rehabilitation",[87,88,89,90,91,92,83,93,94,95,96,97,98],"Surface Electromyography","Electromyography","EMG Biofeedback","Biofeedback","Quadriceps Muscle","Quadriceps Activation","Knee Rehabilitation","Knee Surgery","Motor Control","Neuromuscular Rehabilitation","Single-Case Experimental Design","SCED","NOT_YET_RECRUITING","2026-08-17",{"date":102,"type":103},"2026-08-19","ACTUAL",{"date":105,"type":77},"2026-08-01",{"date":107,"type":77},"2026-12-31",{"name":5,"class":6},1]
