External Versus Internal Feedback in Patients With Chronic Ankle Instability

External Versus Internal Feedback on Biomechanics and Self-reported Function in Patients With Chronic Ankle Instability

• Status: Completed
• Phase: N/A

• Healthy volunteers: Not accepted

Summary

Although altered biomechanics has been well documented as an impairment associated with chronic ankle instability (CAI), effective interventions targeting biomechanics with long-term outcomes measuring patient-reported outcomes (PROs) are absent. Evidence suggests that external focus of attention (ExFOCUS), internal focus of attention (InFOCUS) feedback, and auditory feedback during movement training can alter biomechanics in other patient populations, with ExFOCUS and auditory enhancing retention of learned biomechanics. Therefore, this randomized controlled trial will determine if a 4-week (12 session) impairment-based rehabilitation program that includes feedback (ExFOCUS or InFOCUS or Auditory) can (1) decrease ankle inversion kinematics and lateral plantar pressure during walking and (2) improve self-reported function.

Conditions

• Ankle Injuries
• Ankle Inversion Sprain

Interventions

Type	Name	Description
OTHER	External focus of attention visual feedback	Patients will receive external focus of attention visual feedback during the impairment-based rehabilitation program.
OTHER	External focus of attention auditory feedback	Patients will receive external focus of attention auditory feedback during the impairment-based rehabilitation program.
OTHER	Internal focus of attention video feedback	Patients will receive internal focus of attention visual feedback during the impairment-based rehabilitation program.
OTHER	No feedback	Patients will receive no feedback during the impairment-based rehabilitation program.
