Osteoarthritis (OA) is one of the emerging health issues in Asian countries in elderly population. Knee osteoarthritis (KOA) is a major age related public health issue characterized by progressive loss of articular cartilage resulting in pain, functional impairment, disability and diminished quality of life. The aim of this study was to assess the effectiveness of Isometric exercise and counseling on level of pain among patients with KOA.
Quantitative research approach and a quasi-experimental pretest-posttest control group research design was utilized. The study was conducted at MIOT hospital and Devadoss Hospital, Madurai, Tamil Nadu, India. Data was collected from a total of 200 patients with KOA, 100 in the study and 100 in the control group. These patients were clinically diagnosed to have Grade I, II and III KOA. The demographic variables and clinical profile were recorded for both groups. The self-administered WOMAC questionnaire was used to assess the level of pain of KOA patients. Post-test assessment was carried out on Day 15, Day 30, Day 60 and Day 90. The data was analyzed using SPSS windows 16.
The comparison of level of pain between the study and control group has showed a remarkable reduction in level of pain among patients with KOA in the study group. The post-test level of pain in the study group was 14.9% (13.3% -16.5% with 95% CI) and was 2.1% (1.2% -3.0% with 95% CI) in the control group. It showed that the reduction in the level of pain was higher in the study group than the control group.
The study found that a 12-week Isometric exercise and counseling program has significantly reduced pain, stiffness and improved physical function. Therefore, the Isometric exercise and counselling should be adopted as a routine care in the hospitals treating patients with KOA.
骨关节炎（OA）是亚洲国家老年人群中日益凸显的健康问题之一。膝关节骨关节炎（KOA）是一个与年龄相关的主要公共卫生问题，其特征是关节软骨逐渐丧失，导致疼痛、功能障碍、残疾和生活质量下降。本研究的目的是评估等长运动和咨询对KOA患者疼痛程度的有效性。
采用定量研究方法和准实验性前后测对照组研究设计。该研究在印度泰米尔纳德邦马杜赖的MIOT医院和德瓦多斯医院进行。共收集了200例KOA患者的数据，研究组和对照组各100例。这些患者经临床诊断为I级、II级和III级KOA。记录两组的人口统计学变量和临床资料。采用自行填写的WOMAC问卷评估KOA患者的疼痛程度。在第15天、第30天、第60天和第90天进行后测评估。使用SPSS 16.0软件对数据进行分析。
研究组与对照组疼痛程度的比较显示，研究组KOA患者的疼痛程度显著降低。研究组后测疼痛程度为14.9%（95%CI为13.3%-16.5%），对照组为2.1%（95%CI为1.2%-3.0%）。结果表明，研究组疼痛程度的降低幅度高于对照组。
研究发现，为期12周的等长运动和咨询计划显著减轻了疼痛、僵硬程度，并改善了身体功能。因此，等长运动和咨询应作为治疗KOA患者的医院的常规护理措施。
