Background and Purpose: Approximately 596 per 100,000 people experience lower extremity injuries in the United States each year. Lower extremity (LE) injuries are common injuries experienced by athletes and laypeople and are commonly treated by physical therapists. For moderate or severe injuries, returning to sports or daily activities may take up to 8 weeks. Subsequently, a person with an injury may have altered motor control post-injury. Recent research suggests that the implementation of visual feedback during balance-related activities may result in up-training the dorsal visual stream and result in improved stability and balance abilities. Evidence to support this mode of training is limited and has not been triangulated to standard lower extremity measures used by physical therapists.
Design: A two-group Quasi-Experimental study, using pre and post-intervention measures, will be used.
Methods: A sample of convenience of healthy college students volunteered for testing of lower-extremity excursion using the Y-Balance measure, before and after the basic practice of single-leg squatting. One group received a task-specific practice of single-leg squatting, while one group received a task-specific practice of single-leg squatting with the use of visual feedback. Each group had their baseline measures of hip strength and LE excursion retaken.
Results: Data collection is still in process; data analysis will take place before research days. Comparative analysis will take place to determine any impact the training method may have on the performance of the lower extremity.
