METHODS: TA moment arms were determined using TE and GEO. Errors associated with tendon stretch/hysteresis, talus rotation relative to the foot, and the location of the line of action were investigated. RESULTS: For TE, large errors in moment arm estimates across the range of motion were ...

Spastic equinovarus is the result of muscle hyperactivity in the gastrocsoleus, tibialis posterior and/ortibialis anterior muscles. One third of cases are caused by the tibialis posterior muscle, one third by the tibialis anterior muscle, and one third by overactivity in both the tibialis poste...
Recruitment and derecruitment thresholds were also computed as the torque level (% MVC) at the time when the MU started and stopped firing action potentials, respectively. We then used the paired MU technique (Gorassini et al., 2002, Gorassini et al., 1998) to estimate the contribution of...
After electrode placement onsoleusandtibialis anterior, the participants were seated upright in the chair of an isokinetic dynamometer (Biodex System 4, Biodex Medical system, Shirley, NY) with the knee fully extended (0˚) and ankle in the anatomical position (0˚). A warm-up consisting of...

The surface EMG signals were averaged with the intramuscularly detected MU action potentials as triggers. In this way, eight spatial filter鈥攍ongitudinal and transversal, single and double differential (LSD, TSD, LDD, TDD), Laplacian (NDD), inverse binomial filter of the second order (IB2)...
The main ones are tibialis anterior (TA) transfer, hemi-TA transfer, and retrograde fixation of the distal peroneus brevis (PB) tendon onto the TA [1]. Use of the peroneus longus (PL) has never been described in the literature. Yet, imbalance between TA hypertonicity and fibular muscle ...
