OBJECTIVE: Operative decompression is indicated for progressive @entity16 in @entity1 with @entity1745 ( @entity1745 ). However, the best timing to ensure clinical recovery has not been determined because of the lack of a suitable method. 10 s step ("step") test is an easily performed physical test to assess the severity of @entity1745 , particularly for the severity of @entity6250 . The purpose of this study was to analyze the predictive value of preoperative step test results in relation to the results of expansive laminoplasty in @entity1 with @entity1745 . MATERIALS AND METHODS: Clinical and imaging data were prospectively collected from 101 @entity1 who underwent cervical expansive laminoplasty for @entity1745 . The Japanese Orthopedic Association (JOA) score and the lower limb function section of the Japanese Orthopedic Association Cervical @entity602 Evaluation Questionnaire (JOACMEQ-L) were used to evaluate surgical outcomes. Cutoff value was determined by receiver operating characteristic curve analysis to predict clinical recovery after surgery. JOA recovery rate exceeding 50% was defined as an effective clinical result. The treatment was judged to be effective in 30 @entity1 based on the JOACMEQ-L. The cutoff value of the step test was 14.5 in cases of an effective judgment with JOA and JOACMEQ-L. Multivariate analysis showed that preoperative @entity1 age and duration of symptoms were predictive parameters for effectively judging JOA scores. A preoperative step test result of greater than or equal to 14.5 and male gender were significant predictive parameters for an effective judgment with JOACMEQ-L. CONCLUSIONS: Preoperative step test results significantly reflected the effective results of JOACMEQ-L and were predictive of improved lower limb function after laminoplasty in @entity1 with @entity1745 . @entity1 with a score of greater than or equal to 14.5 can experience effective lower limb functional recovery.
