What we do
About our project
Ankle sprains are one of the most frequent injuries of the musculoskeletal system, with yearly around 680.000 new sprains in the Netherlands. Of these, about 130.000 people will visit the general practitioner (GP) each year. In addition, patients have an increased risk of a recurrent ankle sprain and about a third report at least one re-sprain. No optimal treatment strategy has proven to be effective in general practice, however promising results were achieved in a preventive trial among athletes.
We hypothesize that unsupervised neuromuscular training program in combination with usual care is more effective in the reduction of re-sprains, compared to usual care alone, after a 52 week period.
This study is a multi-center, open-label randomized controlled trial, with a one-year follow-up. Patients with an acute lateral ankle sprain, aged between 14 and 65 years and visiting the GP within three weeks of injury are eligible for inclusion. Patients will be randomized in two study groups. The intervention group will receive, in addition to usual care, a standardized eight-week neuromuscular training program guided by an App. The control group will receive usual care in general practice alone. The primary outcome of this study is the total number of ankle sprain recurrences reported during one year follow-up. Secondary outcomes are subjective recovery after one year follow-up, pain at rest and during activity, function, return to sport, cost-effectiveness and compliance of the intervention. Measurements will take place monthly for the study period of 12 months after baseline measurement.
Our research focus
The primary outcome is the number of re-sprains reported after 1-year follow-up.
a) Subjective recovery after 1-year follow-up
b) Pain at rest and during activity
d) Return to sport
e) Cost-effectiveness of the intervention
f) Compliance of the intervention
