What does the patient need to do?
JAS devices allow patients total control in carrying out their ROM therapy. Because patients control the intensity of stretch, muscle guarding is virtually eliminated.
- During each 30-minute JAS session, patients continually adjust their device to pain-free positions of end-range stretch.
- Each position is held for 5 minutes to allow for tissue relaxation to occur before advancing to a new position of stretch.
The patient is to wear the JAS device at rest and the recommended timings are for 3 x 30-minute sessions per day.
Maximum Total End Range Time (TERT) is achieved for optimal therapeutic benefit.
The key to restoring range of motion (ROM) is not holding or moving the deficient joint in the mid-range but stretching at the very end of its range where the tissues are actually contracted. Holding at the end range for 30 minutes 3 x per day results in the plastic deformation of the contracted tissue back to its native state, with subsequent permanent restoration of mobility at the end range.The total time that a joint is held at its end range is termed the TERT or Total End Range Time.
