Effect of Isometric and Isotonic Exercise Program on Increased Strength of Quardriceps Muscles in Osteoarthritis Patients in Singgasana Rama Physiotherapy Clinic Blitar

Background: Osteoarthritis is a disease of the joints that can cause disability and is progressive in the joints which cause changes in the water content, proteoglycin content, and collagen in the joints. One of the ways to improve functional ability in osteoarthritis cases is to use isotonic and isometric training exercise. Pain is a clinical symptom of knee osteoarthritis, limiting movement due to pain over time will cause rehabilitation problems such as impaired flexibility and stability, reduction of muscle mass (atrophy). Mild and moderate intensity quadriceps strength training is effective at achieving optimal muscle strength and function without causing significant muscle damage. Destination: The purpose of this study was to analyze the effect of isotonic and isometric exercises on muscle strength. Research methods: This study uses a pre-experimental research type using "One Group Pre - test and Post - Test". This research has carried out the first observation (pretest) so that researchers can test the changes that occur after the treatment, and the control group. Result: with the Wilcoxon signed rank test test the isometric and isotonic groups had p = 0.000 while the control group had a significance value of p = 1,000; and the 3 groups test has different values, namely: isotonic exercise has a value of 27.67; isometric; 28.60; and control 12.73. The conclusion that can be concluded that the value of isometric training has the highest value, namely 28.60 which means it is the most effective exercise to increase the value of Manual Muscle Testing. Conclusion: There is an effect of giving isometric and isotonic exercises in strengthening the quadriceps muscles.

Short-Term Effects of Kinesio Taping Combined With Cervical Muscles Multi-angle Isometric Training in Patients With Cervical Spondylosis

Objective: The purpose of this study was to investigate the efficacy of Kinesio taping (KT) combined with multi-angle isometric resistance training for cervical spondylosis. Methods: Sixty-one patients were divided into two groups by random number table method. Both groups were given multi-angle isometric training, the patients in the observation group were supplemented with Kinesio taping. Before and after treatment, the symptoms of cervical spine function were evaluated in two groups by visual analogue scale (VAS), cervical dysfunction index (NDI), cervical range of motion and muscle stiffness.Results: After 3 weeks of treatment, VAS, NDI scores and the cervical range of motion were significantly better than before (P<0.05). The range of anterior flexion and extension was significantly larger than the control group (P<0.05), but the range of other motions were not certain. The muscle stiffness in KT group were significantly lower than the control group.Conclusion: KT combined with multi-angle isometric resistance training can further alleviate the clinical symptoms and correct the neck abnormal posture. But its effects on the range of cervical motion remain uncertain.

Potential Improvement in Rehabilitation Quality of 2019 Novel Coronavirus by Isometric Training System; Is There “Muscle-Lung Cross-Talk”?

The novel Coronavirus Disease 2019 (COVID-19) crisis is now present in more than 200 countries. It started in December 2019 and has, so far, led to more than 149, 470,968 cases, 3,152,121 deaths, and 127,133,013 survivors recovered by 28 April 2021. COVID-19 has a high morbidity, and mortality of 2%, on average, whereas most people are treated after a period of time. Some people who recover from COVID-19 are left with 20 to 30% decreased lung function. In this context, exercise focused on skeletal muscle with minimal lung involvement could potentially play an important role. Regular exercise protects against diseases associated with chronic low-grade systemic inflammation. This long-term effect of exercise may be ascribed to the anti-inflammatory response elicited by an acute bout of exercise, which is partly mediated by muscle-derived myokines. The isometric training system seems to have this feature, because this system is involved with the skeletal muscle as the target tissue. However, no studies have examined the effect of exercise on the treatment and recovery of COVID-19, and, more importantly, “muscle–lung cross-talk” as a mechanism for COVID-19 treatment. It is suggested that this theoretical construct be examined by researchers.

Differential changes in muscle architecture and neuromuscular fatigability induced by isometric resistance training at short and long muscle-tendon unit lengths

Eight weeks of isometric training at a long or short muscle-tendon unit length increased and did not change fascicle length, respectively. The “width” of the torque-angle relationship plateau became broader following isometric training at the long length. Despite marked differences in muscle architecture and functional adaptations between the groups, there was only a small-magnitude improvement in neuromuscular fatigue resistance, which was surprisingly negatively related to increased fascicle length in the long length-training group.
