If reduced holding time in the neutral position is detected during the test procedure for the cervical or lumbar spine, Neurac treatment may begin in a similar position. The treatment consists of isometric holds, which are repeated as long as: 1.The exercise is performed correctly, 2. Pain is not provoked (or increased), 3. Holding time continues to improve before fatigue sets in 4. Holding time increases before rest is needed. The patient is frequently reassessed using regular active functional tests to see if the treatment has reduced the pain and/ or improved function and quality of movement.
