The investigators evaluated 30 patients with subacute and chronic grade I and grade II ankle inversion sprains. Subjects were divided into two cohorts. Half of the patients received mortise separation adjustments to the ankle joint, while half received a placebo treatment (five minutes of ultrasound therapy with the ultrasound turned off). Treatment lasted four weeks and consisted of up to eight visits.
Compared with the placebo group, subjects who underwent adjustments enjoyed significantly more improvement in measures of pain reduction, ankle range of motion and ankle function.JMPT January 2001;24:17-24. http://www.harcourthealth.com/
