EFFICACY OF MUSCLE ENERGY TECHNIQUE AND KINESIOTAPING IN ADDITION TO OTHER PHYSIOTHERAPEUTIC INTERVENTION IN PATIENTS WITH MECHANICAL SACROILIAC JOINT DYSFUNCTION- Non-EQUIVALENT TWO GROUP PRE TEST POST TEST QUASI EXPERIMENTAL DESIGN

Background: Mechanical sacroiliac joint dysfunction (SIJD) defined as pain and stiffness along with restricted range of motion around the sacroiliac joint (SIJ) which is further transmitted to groin, thigh and sometimes lower limb. Aim: The aim of the study to compare the effectiveness of muscle energy technique (MET) and Kinesiotaping (KT) in addition to conventional physiotherapy (CP) in participants with mechanical sacroiliac joint dysfunction Methods: Total 30 individuals with mechanical SIJD (7 male and 23 female, BMI 25.2±2.6 Kg/meter2) with age group between 30 to 50 years were recruited in the present study. METCp group (Muscle energy technique with conventional physiotherapy) received 20 participants and KTCp group (Kinesiotaping with conventional physiotherapy) received 10 participants. Follow-up measurements were taken on baseline, after 2 weeks and after 4th weeks of intervention. PPT, HHD AND MODI these three variables were used as outcome measures. Results: Shapiro-wilk test was used for normality test as number of total participants less than 50. Mann-Whitney U test was used to compare the outcome measures between METCp group and KTCp group. Wilcoxon sign rank test and Friedman test were used within the groups. There was significant improvement in both the groups, but METCp group found to be more significant than KTCp group (P value<0.0001). There was higher effect size among all variables in METCp group rather than KTCp group. Conclusion: Muscle energy technique and Kinesiotaping in addition with conventional physiotherapy is more effective by improving pain threshold, strength and functional performance in patients with mechanical SIJD Key wards: Athletic tape; Low back pain; Manipulation; Pelvic girdle pain; Orthotic tape; Muscle energy technique背景：机械性骶髂关节功能障碍（Mechanical sacroiliac joint dysfunction, SIJD）指骶髂关节（sacroiliac joint, SIJ）周围伴随疼痛、僵硬及活动范围受限，且疼痛可放射至腹股沟、大腿，有时累及下肢。研究目的：本研究旨在对比在常规物理治疗（conventional physiotherapy, CP）基础上，分别联合肌肉能量技术（Muscle energy technique, MET）与肌内效贴（Kinesiotaping, KT）对机械性骶髂关节功能障碍患者的干预效果。方法：本研究共纳入30例机械性SIJD患者，年龄范围为30~50岁，体质量指数为25.2±2.6 kg/m²，其中男性7例、女性23例。将受试者分为两组：METCp组（联合常规物理治疗的肌肉能量技术组）20例，KTCp组（联合常规物理治疗的肌内效贴组）10例。分别于基线、干预2周后及干预4周后开展随访评估。选取压力疼痛阈值（PPT）、手持肌力计（HHD）与功能障碍指数（MODI）作为结局评价指标。由于总受试者人数少于50例，采用Shapiro-Wilk检验进行正态性检验；采用Mann-Whitney U检验比较两组间的结局指标差异；组内比较则采用Wilcoxon符号秩检验与Friedman检验。结果显示两组患者均获得显著改善，但METCp组的改善效果显著优于KTCp组（P值<0.0001），且METCp组各结局指标的效应量均高于KTCp组。结论：在常规物理治疗基础上联用肌肉能量技术或肌内效贴，均可通过提升机械性SIJD患者的疼痛阈值、肌肉力量及功能表现改善病情，其中肌肉能量技术联合方案的疗效更为显著。关键词：运动贴布；腰背痛；手法操作；骨盆带疼痛；矫形贴布；肌肉能量技术
