The VMG recordings were decomposed using wavelet packet analysis, and crystal amplitude estimates were utilized in bi-variate regression models to identify VMG components whose amplitudes best correlated to SFFF. Findings indicate that one crystal was sufficient to accurately predict SFFF in both men (R2 = 0.970, P < 0.0001) and women (R 2 = 0.978, P < 0.0001). Moreover, the best correlations were observed against absolute force, suggesting that VMG recordings are capable of providing a objective and non-invasive measure of joint flexion force using data obtained from a non-pennate muscle during static DCER, and so may have applications in both sports medicine and rehabilitation.
