Existing measurement tools that can evaluate ankle instability have some limitations such as subjectivity and lack of reliability. This study is to address such limitations by assessing ankle instability objectively using an inertial sensor during the Y-balance test used in the field.
Sixteen healthy young males (25.4±2.5 yrs) performed Y-balance test twice pre and post fatigue on the force plate. To induce the fatigue in the ankle joint, calf raises were repeated 50 times with maximal effort. During the Y-balance test, reach distances and subjective ankle instability/fatigue were measured. An inertial sensor attached to the participant’s waist was used to collect 3-direction linear and angular accelerations. Root-mean-square (RMS) value of linear acceleration, 95EV (95% ellipsoid volume), and total distance of the center of pressure (TCOP) were calculated. Dependent t-tests were used to compare dependent variables pre and post fatigue.
Subjective ankle instability/fatigue (Pre vs. Post; p=.031, p=.002 respectively), and RMS values of linear and angular acceleration for the posterior-lateral direction of reach were increased (P-values .02~.04) post-fatigue. However, there were no significant differences in the reach distances and 95EV for all directions. These findings show that measures derived from a wrist-mounted inertial sensor can capture the altered ankle instability induced by fatiguing ankle exercise which is not identified by the Y-balance test only used in the field. This suggests that a wrist-mounted inertial sensor may help provide more accurate evaluation of ankle instability in the clinical and sports settings.
