摘要
Background and Purpose: Cervical spondylotic myelopathy (CSM) may develop postural instability due to compression of spinal cord. Decompression surgery is one of the treatment for CSM; however, whether the postural stability and the functional performance are improved after surgery is still unclear. This study was to examine the surgical effect on the postural stability and functional performance in CSM. Methods: Thirty-six patients with CSM (CSM group) and 26 healthy adults (healthy group) were recruited. Assessments were performed before surgery (baseline), 3 months (T3), 6 months (T6), and 12 months (T12) after surgery. All participants were asked to stand on a force plate for 35 seconds under eyes-open (EO) and eyes-closed (EC) conditions. The mean distance (MDIST) and mean velocity of the center of pressure (MVELO) were calculated. The 10-second step test and the lower extremity function of JOACMEQ (JOACMEQ-LL) were also assessed for functional performance. Results: In the EO condition, the MDIST and the MVELO were significantly decreased at T6 when compared to the baseline and T3. The MDIST was significantly higher in CSM group than in healthy group at baseline and at T3. The MVELO was significantly higher in CSM group than in control group at baseline, T3 and T12. In EC condition, both the MDIST and the MVELO were no significant difference between 4 time points. Both the MDIST and MVELO were significantly higher in CSM group than in control group before surgery at T3, T6 and T12. JOACMEQ-LL was significantly improved from T3 to T12, but the 10-second step test showed no difference after surgery. Conclusion: The functional performance was improved after surgery in CSM. The postural stability improved at the first 6 months, but was still unstable compared to the healthy people. Clinical Relevance: The postural stability of CSM is not fully recovered as healthy people. Therefore, the post-surgery patients need further intervention in balance training for optimizing the postural stability.
