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.
Interventions
PROCEDUREPosteriorization of the talus.
Three sets of a 30-s grade IV anteroposterior mobilization.

Inclusion criteria
* Community-dwelling older adults. * Limited ankle mobility (\< 35 degrees). * Over 60 years.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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) |
