Assessment of Unilateral Lower Limb Muscle Power: Are Unilateral Functional Tests Correlated with Nottingham Power Rig in Healthy Adults?

The study included only healthy participants, so the results may not apply to clinical or injured populations. The sample size was approximately 50, which may not be large enough to detect subtle correlations. A standardized chair height was used, which may not have been optimal for all participants' limb lengths, potentially affecting performance. The functional tests likely measure multiple physical capabilities, such as dynamic balance and strength, making it difficult to isolate muscle power.

The authors report no conflicts of interest and the study received no funding.

Do not interpret the low correlations in the non-dominant leg as evidence that these tests are useful proxies for power. The correlations were still classified as low, and the dominant leg showed negligible correlation, meaning neither leg's functional test results reliably predict actual muscle power output.
