Context: A variety of ankle self-stretching exercises have been recommended to improve ankle-dorsiflexion range of motion (DFROM) in individuals with limited ankle dorsiflexion. A strap can be applied to stabilize the talus and facilitate anterior glide of the distal tibia at the talocrural joint during ankle self stretching exercises. Novel ankle self-stretching using a strap (SSS) may be a useful method of improving ankle DFROM.
Objective: To compare the effects of 2 ankle-stretching techniques (static stretching versus SSS) on ankle DFROM.
Design: Randomized controlled clinical trial.
Setting: University research laboratory.
Patients or Other Participants: Thirty-two participants with
limited active dorsiflexion (,208) while sitting (14 women and 18
men) were recruited.
Main Outcome Measure(s): The participants performed 2
ankle self-stretching techniques (static stretching and SSS) for
3 weeks. Active DFROM (ADFROM), passive DFROM
(PDFROM), and the lunge angle were measured. An independent
t test was used to compare the improvements in these
values before and after the 2 stretching interventions. The level
of statistical significance was set at alpha=.05.
Results: Active DFROM and PDFROM were greater in both
stretching groups after the 3-week interventions. However,
ADFROM, PDFROM, and the lunge angle were greater in the
SSS group than in the static-stretching group (P , .05).
Conclusions: Ankle SSS is recommended to improve
ADFROM, PDFROM, and the lunge angle in individuals with
