“…To assess the outcome of the treatment at the level of 'body structure and function' (as defined by the World Health Organization 1999), many different measures have been used, including electromyography (Hesse et al 1994, Heinen et al 1997b, goniometry (Cosgrove et al 1994, Denislic and Meh 1995, Heinen et al 1997a), muscle torque (Corry et al 1997), the Ashworth scale (Calderon-Gonzalez et al 1994, Denislic and Meh 1995, Heinen et al 1997b) and general gait analysis (Cosgrove et al 1994, Sutherland et al 1999). Eames and colleagues (1999) investigated the effect of BTX-A injections on muscle length and showed that a single injection into the calf led to an increase in gastrocnemius muscle length during gait.…”
