Case Study ET: Part V Posted on 01/11/2013 by joabbott Intrinsic biomechanics may contribute as confounding variables when observing multi joint weight bearing movements. Therefore, by removing these intrinsic dysfunctions we may possibly avoid an error in our analysis of our extrinsic multi-joint screens and therefore maximize our corrective exercise programme for the client. If uncontrolled movement exaggerates ones risk of developing joint degeneration, correcting of these poor mechanics in its infancy is vital to function. Summary The work of Freeman et al in 1965 (a and b) suggested repeated inversion episodes cannot be explained solely by an absence of mechanical ankle stability (MI), as functional instability (FI) can be present without mechanical instability and vice-versa. A number of studies have concentrated on demonstrating such a deficit in ankle unstable populations using a variety of parameters (Robbins & Waked, 1995; Jerosch & Bischof, 1996). Current evidence suggests that mechanoreceptors cannot be confirmed as the most important source of proprioceptive information from peripheral joints, rather information from a variety of receptor resources; muscular, joint, cutaneous is important for motor control (Feuerbach et al., 1994; Tropp, 2002). Therefore, the current right foot injury suffered by our case study might directly alter the motor programming, thus create abnormal uncontrolled movement, as a result of this possibly inciting further risk of injury. Additionally Brown et al. (2008) recommended future research of the two hypothesized groups MI and FI must be differentiated as a result of their research indicating the MI sample group were at greater risk of altered movement patterns compared to the FI Group, consequently more at risk. Functional instability must be considered a viable cause of residual ankle disability and instability (Hertel, 2000), mainly due to the kinetic transition from ankle synergy to hip and lower back synergy (Tropp, 2002).
