Abstract
Purpose: To investigate the presence of head control deficits and its course of recovery after anterior cervical discectomy and fusion (ACDF) surgery in cervical spondylotic myelopathy (CSM) patients. Methods: Thirty-seven CSM patients were assessed for their C2–C7 cervical lordosis, neck Range of Motion (ROM), repositioning accuracy, neck strength as well as surface electromyography of the neck muscle activities during slow head motions. Assessments were performed preoperatively and then at 3- and 6-month postoperatively. Results: No significant difference was found for the C2–C7 cervical lordosis postoperatively at 6-month. ROM was restricted immediately after surgery but recovered over time, however, neck strength remained significantly reduced postoperatively. Reposition accuracy improved immediately after surgery but declined again at 6-month follow-up. In addition, muscle activities required to control head motions showed a continuous reduction postoperatively. Conclusions: Adequate C2–C7 cervical lordosis was maintained in the current study with improvement of slow head motion control and ROM at 6-month. However, improvement in head position sense was not maintained and neck strength showed continuous declination overtime. Assessment and monitoring of head control deficits should be routinely considered in CSM patients. ? 2016, Springer-Verlag Berlin Heidelberg.
