Objective:
To compare the efficacy of short- and long-duration passive stretches with a control treatment for the management of plantarflexion contracture after cast immobilization for ankle fracture.
Design:
Assessor-blinded, randomized controlled trial.
Setting:
Hospital physical therapy outpatient departments.
Participants:
Adults with plantarflexion contracture (N=150) after cast immobilization for ankle fracture. All subjects were weight bearing or partial weight bearing.
Interventions:
Exercise only, exercise plus short-duration passive stretch, and exercise plus long-duration passive stretch. All subjects had a 4-week course of exercises. In addition, subjects in the short-duration stretch plus exercise group completed 6 minutes of stretching per day, and subjects in the long-duration stretch plus exercise group completed 30 minutes of stretching per day.
Main Outcome Measures:
Lower Extremity Functional Scale and passive dorsiflexion range of motion with the knee bent and straight at baseline, and at 4 weeks and 3 months postintervention.
Results:
One hundred thirty-nine (93%) subjects completed the 4-week assessment and 134 (89%) subjects completed the 3-month assessment. There were no statistically significant or clinically important between-group differences for the primary outcomes.
Conclusions:
The addition of passive stretching confers no benefit over exercise alone for the treatment of plantarflexion contracture after cast immobilization for ankle fracture.
