Scientific title
Efficacy of a physical therapy intervention for the early treatment of acute ankle sprains identified in the emergency department: a randomised controlled trial
Acronym
Study hypothesis
What is the efficacy of a standardised physical therapy intervention plus usual emergency medical care, versus usual emergency medical care alone, in enhancing functional recovery at 3 months post-injury?

Condition
Ankle sprain
Intervention
Control arm:
Eligible study subjects assigned to the control arm will receive usual care only. This consists of:
1. Ruling out of ankle fractures and grade 3 ligament ruptures
2. Assessment and advice provided by ED nursing and physician staff according to their practice, supported by
3. A printed set of standard discharge instructions
Experimental arm:
Eligible study subjects assigned to the experimental arm will receive usual care (as per control arm) plus a standardised physical therapy intervention aimed at returning the patient to his/her full pre-morbid activity level. Individuals will be seen by one of two therapists within 2 business days of receiving a referral, and will be seen by the same therapist throughout the treatment course. A treatment plan consisting of thirty minute sessions and home exercise will be developed for each patient based on a standard approach requiring assessment of recovery and progression through 4 stages. We expect most patients will require between 3 and 5 sessions. Those with risk factors for chronic ankle instability (e.g. anterior and inversion laxity, functional insufficiency) may require more.
Stage I is focused on managing the acute/subacute symptoms using modalities to decrease pain and swelling and protecting the joint from secondary inflammation and further injury due to instability while promoting pain-free weight bearing as tolerated. These treatment activities may continue into Stage II, although with reduction in pain, more emphasis on improving passive and active range of motion (ROM) through stretching, mobilisation and progressive resistance exercises introduced. In Stage III a more aggressive approach to regaining full ROM in all movement directions, and building strength and endurance in all muscle groups is adopted to increase joint stability and strength. Individualised progressive resistance programs using isometric, isotonic and isokinetic exercises to strengthen muscle groups throughout the ROM and also combined movements (e.g. circumduction). As the patient achieves full weight-bearing and can tolerate resistance exercise at slow and fast velocities without pain, then proprioception training and activity-specific training can be initiated - the focus of Stage IV. This advanced stage prepares the individual to return to full activity by restoring full strength and joint mobility, reducing mechanical and functional insufficiencies that are risk factors for chronic ankle instability and recurrent injury. Depending on the activity level and risk factors for recurrence and chronic instability, protection may be prescribed during activity.
As part of their treatment, patients will receive a home exercise program which they are encouraged to complete 2 - 3 times/day. These programs will be progressed in difficulty as the individual's strength and tolerance improves.
Outcomes will be measured at 3 and 6 months with the 3-month data being used for the primary analyses.

2. Functional recovery, as assessed by FAOS, at 1 month and 6 months post-injury (in addition to the primary 3 month endpoint)
3. Clinical and laboratory-based outcome measures of ankle recovery
4. Recurrence of sprain injury in the same ankle
