Effects of Talocrural Joint Mobilizations in the Treatment of Subacute Lateral Ankle Sprains
- Conditions
- Ankle Sprain
- Interventions
- Other: Sham interventionOther: Mobilization therapy in addition to standard therapy
- Registration Number
- NCT01117909
- Lead Sponsor
- University of Virginia
- Brief Summary
The goal is to determine if standard therapy including joint mobilizations of the ankle performed 3 times per week for 2 weeks will increase self-reported function and decrease pain in patients with mild lateral ankle sprains.
- Detailed Description
The purpose of this protocol is to assess the effects of grade IV anterior to posterior joint mobilization on self-reported function, dorsiflexion range of motion and talar glide on subjects suffering from lateral ankle sprain in the past 2-10 days and exhibit 5 degree dorsiflexion deficit in range of motion or a restriction in posterior glide of the talus.

- Posterior talar glide restriction greater than 5° compared to uninvolved limb; or
- Posterior talar glide less than 19°, which is one standard deviation (7°) from our previously established normative values (26°)9, 10
- Suffered from grade 1 or 2 lateral ankle sprain within the last 48hr - 8 days
- A history of ankle surgery that involves intra-articular fixation,
- Syndesmotic ankle sprain (to be ruled out based on clinical examination),
- History or signs of reflex sympathetic dystrophy,
- Have received manual therapy for the ankle sprain prior to enrollment

Group Intervention Description "Laying of hands" plus standard therapy Sham intervention Subjects will lie on their back as if they were receiving the joint mobilization treatment and the therapist will place their hands in a position as if to perform the mobilization but no movement will occur. Standard therapy will consist of ankle strengthening exercises with elastic bands, balance, active ROM, and 20 minutes of ice bag application, elevation and compression Standard therapy with joint mobilization Mobilization therapy in addition to standard therapy This group will receive three 60-second bouts of posterior joint mobilizations applied to the ankle joint during each treatment session, in addition to standard therapy. Standard therapy will consist of ankle strengthening exercises with elastic bands, balance, active ROM, and 20 minutes of ice bag application, elevation and compression
- Primary Outcome Measures
Name Time Method Change in self-reported function Baseline and four weeks We hypothesize that the group that receives joint mobilization in addition to standard therapy will show greater improvements in Functional Ankle and Ability Measure (FAAM) and FAAM-Sport (FAAM-S) scores than those who receive standard therapy alone.
Change in self-reported pain Baseline and 4 weeks We hypothesize visual analog scale (VAS) scores for pain will have a greater improvement in those who received joint mobilization in addition to standard therapy when compared to standard therapy alone.
- Secondary Outcome Measures
Name Time Method Change in ankle dorsiflexion range of motion Baseline and 4 weeks We hypothesize that mobilization when applied to the talocrural joint in addition to standard therapy will result in a greater increase of ankle dorsiflexion ROM than just standard therapy alone.
Change in ligamentous laxity Baseline and 4 weeks We hypothesize that ligamentous laxity in both groups will be reduced.
