Hypothesis:
Loss of range of motion after injury or surgery of the elbow is a common complication. We hypothesized that an orthosis that used progressive stretch and stress relaxation principles would improve elbow range of motion.
Methods:
This study evaluated the result of a patient-directed, bidirectional orthosis that uses static progressive stretch and stress relaxation principles to improve elbow range of motion in patients who had posttraumatic elbow contractures. Treatment in 37 elbows consisted of a 30-minute stretching protocol performed in 1 to 3 sessions daily for a mean of 10 weeks (range, 2-22 weeks).
Results:
The mean gain in range of motion was 26 degrees (range, 2 degrees -60 degrees ). Gains of motion were noted in 35 of 37 elbows. Patients lowered their analgesic use and were highly satisfied with the device (mean satisfaction score of 8.5 of 10 points possible).
Discussion:
This device compared favorably with reports of other devices. Consistent improvements in restoring range of motion can be achieved with short treatment times by using a device based on the principles of static progressive stretch and stress relaxation in patients with posttraumatic elbow contractures.

Relaxation of Skeletal Muscles
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open.
