Contractile rate of force development after anterior cruciate ligament reconstruction - a comprehensive review and meta-analysis
- While many studies have examined muscle strength deficits following ACL reconstruction, less is known about rate of force development (RFD) deficits post-op.
BACKGROUND & OBJECTIVE
It is commonplace for ACL reconstruction (ACLR) rehabilitation programs to include resistance training as a means of regaining strength. There are different forms of objective measures for assessing hamstring and quadriceps strength. Typically, a dynamometer is used to obtain a measure of maximum muscle strength with comparison to the uninjured limb to determine a limb symmetry index (LSI). Previous research suggests that up to 50% of people do not achieve hamstring and quadriceps strength >90% LSI at 9 months post-op.
Less is known about how rapidly muscles can produce force (rate of force development; RFD) following ACLR. The authors of this study sought to understand more about RFD limb symmetry following ACLR, but also compared to healthy controls.
Ensure you achieve a healthy, ‘quiet’ joint that has full range and minimal to no pain or swelling before beginning RFD exercises.
Adhering to PRISMA guidelines, a comprehensive literature search was conducted, looking for studies that included variations of ACLR and RFD. 10 studies were included for a systematic review. A total of 246 participants (109 females, 137 males) were included, ranging
