Dose-response of Anteroposterior Mobilizations in Weight Bearing Talus Dorsiflexion

Not Applicable

Completed

• Conditions: Aging Problems
• Interventions: Procedure: Posteriorization of the talus.

• Registration Number: NCT04563663
• Lead Sponsor: University of Valencia

Brief Summary

Ankle mobility limitations are common in older adults. A possible treatment to restore joint mobility is manual therapy based on mobilization techniques, in this case, applied on the ankle joint. Previous research had proposed different treatment volumes (one to twelve sessions), but shown a different and non-consistent degree of effectiveness according to such factor. Therefore, this work aims to determine the dose-response relationship of manual therapy (talus mobilizations) on ankle range of motion in the older adult.

Arm && Interventions

Group	Intervention	Description
One session	Posteriorization of the talus.	One session of talus posteriorization.
Two sessions	Posteriorization of the talus.	Two sessions of talus posteriorization.
Three sessions	Posteriorization of the talus.	Three sessions of talus posteriorization.
Four sessions	Posteriorization of the talus.	Four sessions of talus posteriorization.

Primary Outcome Measures

Name	Time	Method
Treatment dose	Change from baseline to end of intervention (2 weeks) and follow-up (10 weeks)	Number of sessions of experimental intervention needed to induce a clinically important gain in ankle mobility after the intervention. A baseline progression over 4.6º in the Lunge test will be considered clinically important (Powden, 2015), so that the number of sessions will be established when this threshold is exceeded (see secondary outcome) .

Secondary Outcome Measures

Name	Time	Method
The Lunge test	Change from baseline, to end of intervention (2 weeks) and follow-up (10 weeks)	Weight bearing ankle dorsiflexion range of motion. This test will measure the maximum tilt of the tibia that a subject can perform while standing and bearing the weight on the limb without lifting the heel from the floor. A Baseline® Digital Inclinometer (Fabrication Enterprises Inc) will be used to assessed this outcome. Values below 35º indicate limited mobility. A baseline progression over 4.6º will be considered clinically important (Powden, 2015). This mobility gain will be used to determine the dose-response relationship: number of sessions of talus mobilizations needed to induce a clinically important gain in ankle mobility after the intervention (see primary outcome measure)
