Primary Outcome Measures

Name	Time	Method
To determine the cross-sectional area of the selected intrinsic foot muscle abductor hallucis in injured and non-injured tennis players as measured by ultrasound.[Immediately after the ultrasound scan has been completed. ];To determine the cross-sectional area of the selected intrinsic foot muscle flexor digitorum brevis in injured and non-injured tennis players as measured by ultrasound.[Immediately after the ultrasound scan has been completed. ];To determine the composite functional performance of the selected intrinsic foot muscles (both abductor hallucis and flexor digitorum brevis) in injured and non-injured tennis players as measured by the relative pressure changes on the Archercise biofeedback device.[Immediately after the Archercise device exercises have been completed.]
