DDx: ____________ v.s. ____________

A

Caused by: repetitive microtrauma to the origin of wrist extensor muscles
Aka: Tennis Elbow
MOI: inexperienced backstroke
Muscles involved: ECRB>EDC>Brachiorads>ECRL>ECU

S/sx: aching pain at lateral epicondyle

Orthosis: FA band
DDx: Lat Epi v.s. Radial Tunnel Syndrome

  1. Lateral Epicondylitis
    - DDx: Lat Epi vs Rad Tunnel Synd
    Apply pressure at Lat Epicondyle
    If decreased pain = Tennis elbow – de-loading technique
    De-loading the tendon
    If increased pain = Radial syndrome – impinging
