Which statement about the role of isokinetic testing in RTS decisions is most accurate?

• A. It is the only method to determine readiness to return to sport
• B. It never informs decisions about rehab progression
• C. It is inexpensive and universally available
• D. It provides objective strength symmetry data but has limitations such as availability and clinical relevance

Answer: (D)

Isokinetic testing provides objective data on muscle strength and symmetry between limbs, which helps clinicians gauge how close the injured limb is to the uninjured limb and informs RTS decisions. The value lies in having a quantitative measure of symmetry, often using limb symmetry indices to compare the affected and unaffected sides. However, there are important limitations: access to isokinetic machines isn’t universal, the tests can be costly and time-consuming, and the exact strength values don’t always translate directly to sport performance or safe return. Because of this, isokinetic data should be integrated with functional performance tests, movement quality, and clinical assessment rather than used in isolation. The other statements are not accurate because isokinetic testing isn’t the only tool for RTS decisions, isn’t typically inexpensive or universally available, and does inform rather than never influence rehab progression.
