Effect of Fatigue on Kinesthetic Acuity of Healthy Ankle

The purpose of this study was to determine the effect of fatigue on kinesthetic acuity of (Ankle) the gastrocnemius through a dynamic fatiguing protocol in dorsiflexion and plantar flexion of the ankle. Participants: 100 healthy college students volunteered for the study. Subjects meeting any of the following exclusion criteria were excluded from the study: (1) prior history of multiple ankle sprains, (2) an ankle sprain or ankle injury within the last six months, (3) any knee or ankle surgery within the past year, (4) any neurological or central nervous system deficits (5) taking any medication which might affect the nervous system. Main Outcome Measures: The researchers expected that there would be a significant difference in absolute error between the non-fatigued and fatigued condition at both 10º of dorsiflexion and 20º of plantar flexion. Results: There was significant main effect of fatigue on kinesthetic of healthy ankle. Conclusion: The results of this study indicated that there was significant difference between the non-fatigued and fatigued conditions at 10º of dorsiflexion and 20º of plantar flexion measurements.
