A Quasi experimental design was adopted for this study to find out the effectiveness of quadriceps strengthening exercise program on pain and functional ability of women with knee osteoarthritis (OA). Fifty women with OA were selected in which first 25 women were enrolled in the control group and second 25 women were allotted in the exercise group. Assessments were performed at baseline and at 8 weeks. The functional ability was assessed using the Timed Up and Go (TUG) test and Numerical Rating Scale (NRS) was used to assess the pain level .For the exercise group, quadriceps strengthening exercises were taught and asked the patients to follow the exercise schedule for 8 weeks. The study results show that the pain and functional abilty scores were improved in the exercise group and the difference was statistically significant (p<0.001). The study concluded that a simple quadriceps strengthening exercise programme can significantly improve self reported knee pain and functional ability among women with Knee osteoarthritis.

Purpose] The aim of present study was to investigate the effects of isometric quadriceps exercise on muscle strength, pain, and function in knee osteoarthritis. [Subjects and Methods] Outpatients (N=42, 21 per group; age range 40-65 years; 13 men and 29 women) with osteoarthritis of the knee participated in the study. The experimental group performed isometric exercises including isometric quadriceps, straight leg raising, and isometric hip adduction exercise 5 days a week for 5 weeks, whereas the control group did not performed any exercise program. The outcome measures or dependent variables selected for this study were pain intensity, isometric quadriceps strength, and knee function. These variables were measured using the Numerical Rating Scale (NRS), strength gauge device, and reduced WOMAC index, respectively. All the measurements were taken at baseline (week 0) and at the end of the trial at week 5. [Results] In between-group comparisons, the maximum isometric quadriceps strength, reduction in pain intensity, and improvement in function in the isometric exercise group at the end of the 5th week were significantly greater than those of the control group (p<0.05).

BackgroundPrimary knee osteoarthritis is a significant cause of impairment of the lower limb’s mobility, making effective rehabilitation particularly important. This study aimed to identify the association of quadriceps strength with pain and disability in comparison to its association with increasing severity of radiological grades of knee osteoarthritis.Methods50 subjects above the age of 40 years with different grades of knee osteoarthritis were evaluated for their radiological grade of osteoarthritis using Kellgren-Lawrence grading criteria for the knee radiographs, isometric quadriceps muscle strength using a modified hand-held dynamometer, pain, and disability using WOMAC questionnaire, all on the same day in this cross-sectional study.ResultsThere is a significant negative correlation between K/L grade and maximum strength of the quadriceps muscle, r(50) = -0.28(p<0.05). We found a highly significant negative correlation between WOMAC score and strength of the quadriceps m...

Background: Osteoarthritis a common disease of aged population and one of the leading causes of Joints disability. Knee Osteoarthritis is one of the most prevalent joint diseases with a prevalence of 22% to 39% in India. Worldwide OA is estimated to be the 4th leading cause of Joint disability, in which 10% are the male and 13% are the female. Early intervention is considered important for ameliorating the long-term effects of disease. Several studies have shown that quadriceps strengthening exercises may ameliorate joint pain in subjects with knee Osteoarthritis. Strengthening exercise are effective and helpful for reducing pain in knee osteoarthritis. Aim: The aim of this study is to evaluate the effect of quadriceps and hip abductor muscles strengthening versus effects of quadriceps and hamstring muscles strengthening in treating knee Osteoarthritis. Materials and Method: Seventy subjects selected as per inclusion criteria who diagnosed with knee Osteoarthritis. Subjects were divided into group-1 and group-2. The first group received strengthening exercise for the quadriceps and abductor components. The second group received strengthening exercise for the quadriceps and hamstring components and the treatment lasted for 6-7 weeks and the primary outcome will be the Western Ontario and McMaster universities osteoarthritis index (WOMAC) scale. Results: A Wilcoxon test was used for intragroup pre-treatment and post-treatment comparison of WOMAC and Mann Whitney U test was used for intergroup Post-treatment of WOMAC. The P value is 0.001. The mean for the group-A Post WOMAC score is 47.1143 which is less than the group-B Post WOMAC score, so it suggests an improvement. So there is sufficient information to reject and accept the type of hypothesis. Conclusion: It is generally seen in many clinical set ups for treatment of OA of knee that exercises are often prescribed only for strengthening of quadriceps components but rarely for abductor so this study will helpful to design and describe the exercises to strengthen abductor muscles components also and help to improve Pain, disability and function activities in better way.
Effects of isometric quadriceps muscle strengthening exercise on chronic osteoarthritis of the knee

A total of 64 patients of osteoarthritis of the knee joints were studied to observe the effects of isometric quadriceps muscle strengthening exercise plus non-steroidal anti-inflammatory drugs (NSAIDs) on osteoarthritis of knee joints. Another 75 patients were treated with NSAIDs as control. They were assessed by visual analogue scale, OMAC scale and range of motion of the knee joints and followed-up weekly for six weeks. Improvement was found in both groups (p= 0.001) after treatment. In comparison, more improvement was found in the exercise group after four weeks (p= 009). Then improvement was gradually increased day by day and finally there was highly significant improvement (p=0.001). This study suggests that isometric quadriceps muscle strengthening exercise has its beneficial role to reduce symptoms in osteoarthritis knee.Online: 18 July 2010DOI: http://dx.doi.org/10.3329/bmrcb.v36i1.5502Bangladesh Med Res Counc Bull 2010; 36: 20-22

Background: Knee osteoarthritis (OA) is one of the major causes of dysfunction that reduces patients' quality of life. The aim of current study was to investigate the effectiveness of muscle strengthening exercises on the clinical outcomes of patients with knee OA. Methods: We conducted a single-blind clinical trial on 96 patients with mild to moderate knee osteoarthritis. Patients were randomly assigned to 4 groups with 24 patients and followed-up for 8 weeks. Quadriceps, hamstring and both hamstring and quadriceps strengthening exercises were received by the first (G1), second (G2) and third (G3) groups, respectively. The fourth group (G4) was the control group and did not receive any intervention. The main outcome variables were pain, physical function and morning stiffness. This study was retrospectively registered at irct.ir (Iranian Registry of Clinical Trials) with the code IRCT20220206053950N2, 2022-09-07 Results: Our findings demonstrated a significant impact of interventions on VAS score, pain, and stiffness (All, p < 0.001). Nonetheless, the effect of interventions was not significant for physical function (P = 0.78). After adjusting for the potential confounders, similar results were observed. Besides, the results of Dunnett post hoc test showed that either G1 or G3 had the most decrease in VAS and WOMAC-morning stiffness scores compared to G2 and G4. Conclusion: Based on the evidence from the present study, we can recommend a combination of quadriceps and hamstring strengthening exercises as the most effective intervention to reduce pain and morning stiffness in patients with OA.
