Official title
Effects of Quadriceps Focused Interventions in Adolescent With ACL Reconstruction
Overview
The purpose of this study is to characterize quadriceps function and squat biomechanics during the early strengthening phase in adolescent patients undergoing a standardized combined neuromuscular electrical stimulation (NMES) and blood flow restriction (BFR) rehabilitation protocol
Interventions
- Other NMES and BFR
NMES is applied when patients perform quadriceps strengthening exercises. BFR is applied during compound exercises. - Other Standard physical therapy
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.
Primary outcome measures
- Peak force as measured by isometric knee extension force test [Time frame: 12 and 16 weeks post surgery]
- Force steadiness as measured by isometric knee extension force test [Time frame: 12 and 16 weeks post surgery]
Secondary outcome measures (3)
- Sagittal plane peak angle at the hip during the descending phase of the squat [Time frame: 12 and 16 weeks post surgery]
- Sagittal plane peak angle at the knee during the descending phase of the squat [Time frame: 12 and 16 weeks post surgery]
- Sagittal plane peak angle at the ankle during the descending phase of the squat [Time frame: 12 and 16 weeks post surgery]
Eligibility criteria
Inclusion criteria
- no history of knee injury/surgery of the contralateral limb
Exclusion criteria
- (1) bilateral knee injuries
- (2) prior knee ligament injury and/or surgery
- (3) multiple ligament injuries and/or ruptures
- (4) conditions in which NMES and BFR are contraindicated
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
