Figure 2 Line graph showing mean (SEM) values for ankle function, assessed using Binkley's lower extremity functional scale,¹⁶ for intermittent and standard groups at baseline and week 1, 2, 3, 4, and 6 after injury. Values for the interaction time × group (within subject factor  =  time; between subject factor  =  treatment group): F  =  1.951; df  =  5; df error  =  340; p  =  0.85. Sphericity was assumed, as Greenhouse‐Geisser's procedure produced a non‐significant F ratio.
