Comparison of the effectiveness of isokinetic exercise vs isometric exercise performed at different angles in patients with knee osteoarthritis

Osteoarthritis is a chronic degenerative disorder that primarily affects the articular cartilage of the synovial joint, and ultimately bone and remodeling (spurs) at the joint boundary occur. Synovial thickening and capsule progression and joint effusion also occur. Disorders due to Osteoarthritis cause limited activity and limited ability in activities. Because, damage to the cartilage (cartilage) of the joint, so that the thickness of the subcondral bone increases, sclerosis of the bone plate, the growth of osteophytes in the joints, can stretch the joint capsule, resulting in inflammation, and weakening of the muscles connecting the joints. This study aimed to determine the effect of Manual Traction and Isometric Exercise in patients with Knee Osteoarthritis at Grandmed Lubuk Pakam Hospital. Using quasi experiments with one group pretest posttest with a sample of 19 respondents. Measurement of Functional Activity with Jette Scale, using paired sample t-test analysis. There is a significant influence on functional activities before and after. hypothesis test by paired sample t-test obtained with the results of p-value < α (0.001 <0.05). There is the Effect of Manual Traction and Isometric Exercise on Functional Activity Enhancement in Patients with Knee Osteoarthritis at Grandmed Lubuk Pakam Hospital. Researchers suggest that the next researcher add a number of samples and a longer time so that the results obtained are more maximal.

Background and Objectives: Muscle strengthening exercise is suggested to beneficial for patients with knee osteoarthritis (OA) and electrical muscular stimulation is reported to be effective in improvement of muscle strength. This study examined whether isometric exercise combined with whole body-electromyostimulation (WB-EMS) can improve serum cytokine levels, muscle strength, and knee function in elderly women with early knee OA.Materials and Methods: This randomized controlled study included 75 participants assigned into three groups: the control group (CON), isometric exercise group (ISOM), and isometric exercise and electromyostimulation group (ISOM + EMS). The two exercise groups performed their respective programs for 8 weeks, 3 days a week, 30 min a day. The main exercises for both groups were performed continuously during the 20 min in an alternation of a 6-s contraction with a 4-s break. At pre- and post-intervention, anthropometric variables, muscle strength, Knee Injury and Osteoarthritis Outcome Score (KOOS), and blood sampling for biomarkers including interleukin-6, tumor necrosis factor-α, C-reactive protein, and resistin were performed.Results: All variables at pre-intervention showed no significant differences among the three groups. However, there were significant differences between groups for body composition, muscle strength, KOOS subscale scores, and biomarkers. ISOM + EMS group resulted in a significant reduction in body weight, fat mass, fat percentage, inflammatory cytokine levels, and increased muscle strength. An ISOM + EMS group had the best KOOS score among all groups.Conclusion: Isometric exercise combined with WB-EMS resulted in the best overall improvements in knee function and alleviating the pain and symptoms of patients with early knee OA. Further, reduced levels of inflammatory cytokines were observed. These non-pharmacologic, non-invasive interventions should be considered by healthcare specialists for elderly patients with early knee OA.

Introduction: Knee osteoarthritis is a common disease, particularly in the elderly population. Degenerative disorders of the cartilage cause pain and stiffness in the knee joint. As a result, patients frequently experience limitation in their daily activities. Purpose: To compare the effects of exercise, acupuncture, and magnet therapy on symptoms and physical function among middle-aged and elderly people with knee osteoarthritis. Materials and methods: We carried out a parallel three-arm randomized clinical trial in an outpatient clinic of the Department of Physical Medicine and Rehabilitation at a University Hospital. In total, 60 female patients of age ≥ 40 years with chronic knee osteoarthritis were randomly allocated to one of three groups of isometric exercise, acupuncture, and magnet therapy. The primary outcome measure was subjective pain rated according to the Visual Analog Scale. We also used the Western Ontario McMaster Universities Osteoarthritis Index for assessing and monitoring the symptoms of knee osteoarthritis in order to evaluate the efficacy of the interventions. An isometric exercise program was prescribed, consisting of three sessions per week for six weeks. Participants in the acupuncture group received three treatment sessions per week for six weeks, each lasting for 30 minutes. For pulsed electro-magnetic field therapy, a total of three 30-minute sessions per week for a period of 6 weeks were administered to each patient. Results: There were no statistically significant differences between the study groups in terms of the outcome measures (all p values > 0.05). However, within-group analyses showed that there were significant differences regarding the clinical outcomes in each group (all p values < 0.05). Conclusion: All three therapeutic modalities are effective and could be used as the first line of treatment for knee osteoarthritis. Moreover, it should be noted that the favorable outcomes remained at least two months after treatment concluded.

Introduction 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. Methods 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. Results 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. Conclusion 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.
