Assessment of static progressive stretch for the treatment of shoulder stiffness: a prospective case series.

INTRODUCTION: The purpose of this study was to evaluate the use of a patient-directed static progressive stretch orthosis for the treatment of shoulder stiffness. METHODS: Twenty-three patients who had limitations in range of motion of the shoulder and who had failed conventional physical therapy methods were studied. This cohort included 15 women and 8 men with a mean age of 53 years. Treatment comprised one to three 30- to 60-minute sessions per day with a patient-controlled orthosis utilizing static progressive stretch. The patients adjusted the degree of stretch at 5-minute intervals as tolerated. Compliance, range of motion, patient satisfaction, and complications were assessed, and a two-way repeated measure ANOVA was performed to assess the effects of age or gender. RESULTS: After a mean treatment duration of 10 weeks (range, 4 to 19 weeks), the patients gained a mean of 22° (range, -47 to 57°) of external rotation, 18° (range, -19 to 55°) of internal rotation, 46° (range, 3 to 97°) of abduction, and 23° (range, 3 to 40°) of forward flexion. In total, 22 of 23 patients (96%) experienced increases in range of motion that were maintained at 1 year following treatment. Statistically significant increases in range of motion and clinical function scores were noted; age and gender did not appear to influence the outcomes. DISCUSSION: This device compared favorably to other treatment methods for shoulder stiffness. An orthosis utilizing static progressive stretch was a useful adjunct for the treatment of shoulder stiffness refractory to conventional therapy.

Static progressive stretch for the treatment of knee stiffness.

Persistent knee stiffness is common after knee arthroplasties, cruciate ligament repairs, and trauma. Static progressive stretch protocols have shown success in treating contractures of the elbow, ankle, and knee in case reports and small case series. This study evaluated static progressive stretch as a treatment method for patients who had refractory knee stiffness, and compared the outcomes to published results of other therapeutic modalities. Forty-one patients who had knee stiffness and who had not improved with conventional physical therapy modalities were treated with a patient-directed orthosis that utilized the principles of static progressive stretch. After a mean of 9 weeks of use (range, 3 to 27 weeks), the total arc of motion increased by a mean of 33 degrees (range, 0 to 85 degrees ). Forty of 41 patients had increased motion at a mean final follow-up time of 1 year (range, 6 months to 2 years), and 93% were satisfied with the results. The outcomes were comparable to other nonoperative treatments reported in the literature, but the results in the present study occurred in a shorter mean treatment time. An orthosis that utilizes the principles of static progressive stretch may be a successful treatment for improving the range of motion and satisfaction of patients who have knee contractures.
