STUDY DESIGN: Longitudinal observational cohort.
OBJECTIVES: The purpose of this study was to evaluate the utility of Quantitative Romberg measurements as pre-op and post-op balance outcome measures.
SUMMARY OF BACKGROUND DATA: Cervical spondylotic myelopathy (CSM) is characterized by balance deficiencies produced by impaired proprioception. Evaluation is subjective, and binary physical exam findings lack the precision to assess postoperative outcome improvement.
METHODS: CSM patients were prospectively enrolled to undergo preoperative and postoperative Quantitative Romberg tests on a force plate to record center of pressure (COP) motion for 30 seconds with eyes open followed by eyes closed. Revision cases were excluded. Kinematics of COP movement parameters were compared between preoperative and postoperative state for each patient.
RESULTS: Twenty-seven CSM patients were enrolled and completed both pre/post-testing. The mean age was 60.0 years, with 13 (48%) males and 9 (33%) smokers. Mean number of surgical levels was 2.48. The minimum mean follow-up was six months. There was a statistically significant improvement in eyes closed after surgery compared with preoperative for total COP motion (523.44 vs. 387.00 cm, P <0.001), average sway speed (17.41 vs. 13.00 cm/s, P <0.001), and total lateral COP motion (253.44 vs. 186.70 cm, P <0.001). There was no statistically significant improvement in the modified Japanese Orthopaedic Association (13.29 vs. 14.29, P =0.28).
CONCLUSIONS: CSM balance findings on Quantitative Romberg testing significantly improve postoperatively in patients with CSM. These findings support this testing as representative of proprioceptive balance deficiencies seen in CSM. Quantitative Romberg may be used as an objective measure of clinical outcome and assist in stratification of surgical interventions, surgery timing, and technique.
