“…The GA has a wide use for quantification of surgical treatment for correction of equinus foot in CP. A large number of studies have quantified the effects of surgery demonstrating a significant reduction of equines foot, with improvements in the biomechanical position of the ankle and knee as well as an increase or absence of change in muscle energy of the ankle following surgery, and thus an improvement in gait performance (Dreher et al, 2013;Filho, Yoshida, Carvalho, Stein, & Novo, 2008;Galli, Cimolin, Crivellini, & Albertini, 2005;Galli, Cimolin, Crivellini, & Albertini, 2009;Patikas et al, 2007;Seniorou, Thompson, & Theologis, 2006;Sung et al, 2013;Van Bemmel, Van der Bekerom, Verhart, Diederik, & Vergroesen, 2012;Wren et al, 2013). Generally these studies have been conducted using specific parameters obtained by GA (time/distance parameters, angles joint values in specific gait cycle instant, peaks of angles joint).…”
