The Effect of Strain-counterstrain on Ankle Instability

Not Applicable

Terminated

• Conditions: Other Instability, Ankle and Foot
• Interventions: Other: Strain Counterstrain; Other: Sham strain counterstrain

• Registration Number: NCT02025569
• Lead Sponsor: Long Island University

Brief Summary

This study seeks to determine the effectiveness of Strain Counterstrain in the treatment of chronic ankle instability.

Detailed Description

This study aimed to determine the effect of Strain Counterstrain (SCS) on dynamic balance and subjective sense of instability in individuals with chronic ankle instability (CAI). Although many studies have been published on CAI, the cause for this common clinical dysfunction remains inconclusive. No studies have assessed the effectiveness of SCS on CAI. Baseline information on all participants includes a demographic questionnaire, the Star Excursion Balance Test (SEBT), and the Foot and Ankle Ability Measure (FAAM). Participants were randomized into the SCS intervention group or the sham SCS control group. All participants received an intervention (as assigned) once a week for four weeks in addition to performing a prescribed home exercise program. At week four all participants repeated the outcome measures and completed a Global Rating of Change (GROC) form. The primary aim was examined with a 2-way analysis of variance (ANOVA).

Primary Outcome Measures

Name	Time	Method
Star Excursion Balance Test	4 weeks	A measure assessing dynamic standing balance as the individual stands on one leg and reaches, with the other leg, in eight different directions. The distances reached with the non-stance leg are measured.
