客观功能损伤评估用于腰椎间盘退行性病变患者的严重性分层的价值

The value of objective functional impairment assessment for severe stratification in patients with lumbar intervertebral disc degeneration

目的探讨基于"起立-行走"计时测试(TUG)的客观功能损伤(OFI)评估腰椎间盘退行性病变(LDDD)患者严重程度分层的价值。方法 188例LDDD患者术前接受TUG测试、背痛和腿痛的VAS评分、RMDI评分、ODI评分、EQ-5D评分、SF-12评分,根据术前TUG时间对患者进行OFI分层。结果 115例(61. 2%)为无OFI,25例(13. 3%)为轻度OFI,28例(14. 9%)为中度OFI,20例(10. 6%)为重度OFI。背痛和腿痛VAS评分、RMDI评分、ODI评分随着OFI分层增加而增加,EQ-5D评分、SF-12评分随OFI分层增加而下降(P <0. 05)。OFI分层等级每增加一级,背痛VAS、腿痛VAS、ODI、RMDI评分分别增加0. 42、0. 76、5. 57、1. 89分(P <0. 05),而EQ-5D、SF-12 PCS、SF-12 MCS评分分别降低0. 07、1. 18、2. 28分(P <0. 05)。结论 OFI评估能够有效用于LDDD患者的腰椎功能损伤和生活质量分层。

Objective To investigate the value of the objective function injury(OFI)based on“time up and go”test(TUG)to stratify the severity of patients with lumbar degenerative disc disease(LDDD).Methods The 188 patients with LDDD underwent the evaluation of TUG testing,VAS for back and leg pain,RMDI scores,ODI scores,EQ-5D scores,SF-12 score.All patients were classified of OFI degree according to the preoperative TUG time.Results The 115 cases(61.2%)were non-OFI,25(13.3%)were mild-OFI,28(14.9%)were moderate-OFI and 20(10.6%)were severe-OFI.Back pain and leg pain VAS,RMDI score and ODI score increased with the increase of OFI degree;EQ-5D score and SF-12 score decreased with the increase of OFI degree(P<0.05).For each level increasing of OFI degree,back pain and leg pain VAS,ODI and RMDI were increased 0.42,0.76,5.57,1.89 scores,respectively(P<0.05),while EQ-5D,SF-12 PCS and SF-12 MCS score were reduced 0.07,1.18 and 2.28 scores,respectively(P<0.05).Conclusions OFI stratification works well for assessment of lumbar functional injury and quality of life in patients with LDDD.
