Official title
Comparison of Two Programs Delivered During Rehabilitation Before an Anteriror Cruciate Ligament Reconstruction : a Randomised Controlled Trial K-POP
Overview
Muscle qualities are critical for the recovery after an anterior cruciate ligament (ACL) injury. Before ACL reconstruction (ALCR), resistance training aims to maintain patient strength and volume in order to optimize recovery. Unanswered questions remain on the modalities of resistance training before ACLR. This protocol details a pragmatic clinical trial that primary aims to increase the maximal strength of knee extensors and flexors and to induce hypertrophy before ACLR. Participants awaiting ACLR will be recruited from outpatient rehabilitation clinics and will be randomly allocated to one group to attend a 9-weeks rehabilitation program before ACLR. Participants of 'resistance training' group will perform a training program built on the principles of strength training to increase knee muscles strength and volume. Three blocks of 3 weeks will induce a progressive increase in training load, with exercises performed close to failure. Participants of 'usual group' will perform traditional exercises including: balance/proprioceptive exercises, weight-balances exercises, and body-weight resistance training exercises. Groups will be compared on muscle strength (primary outcome), clinical outcomes (muscle volume, stiffness, knee mobility, effusion) and self-reported outcomes (quality of life, perception of knee function, pain, anxiety and depression, exertion, health consumption, participations in activities) before and after ACLR. Outcomes will be collected by a blinded assessor before and after the resistance training program (before ACLR); 4 and 9 months after the ACLR.
Interventions
- Other Resistance training
Participants of 'resistance training' group will perform a training program built on the principles of strength training to increase knee muscles strength and volume. Three blocks of 3 weeks will induce a progressive increase in training load, with exercises performed close to failure. The exercising part for participants of 'RT group' will be composed by a progressive increase in load over the 9 weeks. For that purpose, the intensity of load will be increased each 3 weeks (i.e. on the session 1 - Other Traditional exercises
Participants of 'usual group' will perform traditional exercises including: balance/proprioceptive exercises, weight-balances exercises, and body-weight resistance training exercises. The exercising part for participants of 'usual training group' will comport traditional exercises used in prehabilitation, including: balance/proprioceptive exercises, weight-balances exercises, and body-weight resistance training exercises. Again, the 9 weeks will be sub-divided into 3 blocks of 3 weeks for induc
