Mobilization techniques in chronic ankle instability
Ankle inversion sprains are reported as being the most commonly occurring sport related injury. Following recovery and rehabilitation it is often observed that inversion injuries will result in chronic ankle instability (CAI). Deficits in dorsiflexion are often associated with CAI and have been linked with recurrent sprains therefore manual therapy is commonly utilized to restore limitations in talocrural arthrokinematics. With this in mind, the current study compared the effects of mobilization with movement (MWM) and talocrural manipulation. Overall, it was shown that both techniques increase ankle dorsiflexion in patients with CAI with effects that last several days post treatment.
52 patients screened to have CAI were randomly allocated to either placebo, high-velocity and low grade manipulation or MWM treatment groups. Dorsiflexion was measured in a weight bearing lunge position before and after: immediately, 10 minutes, 24 hours and 48 hours.
This study is the first to directly compare MWM and manipulation on patients with CAI. Despite both intervention groups showing an increase in dorsiflexion, MWM had a larger effect size than manipulation overall. These changes were shown to be sustained for up 48 hours afterwards. Clinically, the authors note that this new information allows clinicians to optimize treatment planning and that effective manual therapy likely does not need to be applied daily.
