Interventions

  • NMES and BFR — OTHER
    NMES is applied when patients perform quadriceps strengthening exercises. BFR is applied during compound exercises.
  • Standard physical therapy — OTHER
    Standard physical therapy (week 1-16) includes interventions for typical impairments following ACLR. The initial phase will focus on pain and effusion control, restoration of knee range of motion, followed by gait normalization, lower extremity strength training, then running and plyometrics.

Study Details

The purpose of this study is to investigate the effects of quadriceps focused interventions on knee function and biomechanics in adolescent patients with anterior cruciate ligament reconstruction (ACLR)

Arms

  • Experimental: Additional neuromuscular electrical stimulation (NMES) and blood flow restriction (BFR)
    Participants receive a 6-week NMES intervention from week 1 to week 6 post-surgery, followed by a 10-week BFR intervention from week 7 to week 16. Participants also receive standard rehabilitation care as part of their routine postsurgical recovery process.
  • Active Comparator: Standard rehabilitation
    Participants receive standard rehabilitation care as part of their routine postsurgical recovery process.

Primary Outcome Measure

Peak force as measured by isometric knee extension force test [ Time Frame: 16 weeks post surgery ]
