The switching of behavior, from the hyperchaotic to controlled magnetoconvection model, is studied by a feedback control technique. The magnetoconvection model shows hyperchaotic oscillations for different values of parameters: Rayleigh number r, Chandrasekhar number Q, and diffusivity ratio l. Chaotic responses of the magnetoconvection model are considered through boundedness and Lyapunov exponents to specify the place where the controller needs to be applied. The controller for the magnetoconvection model is calculated by using the concept of the Lie derivative, which is the most significant facet of control analytical techniques. Speed and dislocated feedback techniques are also utilized with the consideration of stability analysis through feedback gains. To show the advantages of the feedback control technique, we give a comparison with other control techniques such as speed and dislocated feedback techniques. Simulation results indicate that the analytical strategy for controlling the oscillation is effective and controlled within a small duration of time.
Osteoarthritis (OA) of the knee is a relatively prevalent disorder, and prevalence rises with age. Total knee replacement surgery (TKA) is a frequent operation that has significantly improved the quality of life for millions of people with symptomatic knee OA. TKA postoperative care has been discussed regarding the utility of CPM; it has been shown to speed up the recovery of full range of motion, shorten hospital stays, lessen discomfort, speed up wound healing, and lower the risk of DVT. The current study was conducted to compare Effectiveness of CPM protocol as an adjunct to Standard Physiotherapy protocol in Post-operative Rehabilitation of TKA cases. From July to December 2021, three affiliated hospitals hosted the randomised controlled study, which included patients who had complete knee arthroplasty surgery. After surgery, patients were randomly allocated to one of two groups: From the first surgical day till discharge, Group A got twice daily PT and continuous passive motion (CPM), while Group B only received the usual physiotherapy programme from the first postoperative day. Evaluation of the results took place the day after discharge. The participants in the 2 groups' baseline outcome measurement characteristics were comparable.
Background: shin splints are depicting a condition in which leg torment and distress in distal posteromedial part of leg is brought about by dreary action and it rejects reasons for torment because of stress cracks or because of ischemia. Purpose of study: Study aimed to find the prevalence of shin splints among treadmill users in gym. Materials & Methods: The study was observational cross-sectional survey. Purposive sampling was done. 152 data were collected from different gyms of Lahore, Faisalabad and Sargodha, Pakistan. Both male and females aged 18-25 years with duration of gym from last 6 months at least 3 days a week and currently using gym were included in study while person with any physical and anatomical disability or history of surgery of lower limb and systemic illness. (e.g., deep venous thrombosis) were excluded from study. Data was analyzed using SPSS V 23. Descriptive statistics in form of frequency and percentages was presented. Pie and bar charts were plotted. Data was collected through self-devised questionnaire and Medial Tibial Stress Syndrome Score and Ankle Brachial Index and Shin Palpation Test were applied Results: Mean age of participants was 21 years. Out of 140 participants after systemic disease exclusion 87% participants felt pain in lower leg. While 57.1 (n=80) showed some or moderate arterial diseases when evaluated through Ankle Brachial Index. 17.9% (n=25) showed positive shin palpation indicating shin splints. Shin splints were twice as likely to occur in physically active people who had previously reported a running-related injury. To stop the problem from worsening, it is crucial to determine whether treadmill users have shin splints. This study was carried out in Sargodha, Punjab, to discover shin splints in treadmill users. The purpose of this study was to shed light on the frequency and origin of shin splints among treadmill users. Athletes who experience medial shin pain (MSP) may be unable to run. The incidence especially among treadmill users was not previously investigated. Since there was no literature on the population chosen, this topic was chosen. Conclusion: Use of treadmill is one of causes of shin splint and factors associated were duration of treadmill use and supervised use of treadmill while person with shin splint have pain during walking, sporting and running activities which reduced activities. Keywords: Shin Splints, Medial Tibial Stress Syndrome, Treadmill, Gym.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
