Decrease in elbow flexor inhibition after cervical spine manipulation in patients with chronic neck pain.

摘要: Objectives. This study measured functional capacity and subjective pain in patients with chronic neck before after manipulation of the cervical spine. Design. Outcomes on 16 pain. Background. Muscle inhibition, i.e., inability to fully activate a muscle, has been observed following joint pathologies low back conditions. Although associated changes muscle recruitment coordination shoulder arms, possibility inhibition not explored. Methods. Biceps activation during maximal voluntary elbow flexor contraction was assessed using interpolated twitch technique electromyography. Cervical range motion pressure thresholds were goniometer an algometer. Manipulation spine applied at level C5/6/7, assessments repeated. Results. Patients showed significant their biceps muscles. restricted laterally, increased sensitivity evident. After manipulation, reduction increase force occurred. significantly. Conclusions. Significant dysfunction evident pain, indicating that this group cannot be used full extent. Spinal decreased strength least short term. Relevance Muscle previously documented pain. Further research is needed establish whether related clinical symptoms outcome. improved function, sensitivity, might therefore beneficial for treating
