Diabetes mellitus is a chronic metabolic disease, characterized by hyperglycemia resulting in insulin secretion deficits, insulin action or both and highly glycated hemoglobin, higher in elderly than in younger population. Generally skeletal muscle tissue is responsible for 40% of body weight and considered as major site of insulin mediated glucose uptake, which accounts approximately 75% of whole body insulin stimulated glucose uptake  Therefore decrease in muscle strength especially in lower limbs is depicted by the insulin resistance, metabolic inflexibility and neuro muscular impairments.Earlier studies have stated that Diabetes mellitus is associated with loss of muscle strength in distal extremity of lower limb. There is a growing evidences which shows the complication of type 2 diabetes may translate into the functional impairment in older people, this might link the metabolic and mechanical function of the muscle

  Henceforth the evaluation of the lower extremity muscle strength can be assessed by hand held dynamometer, for knee extensors, ankle dorsiflexors, plantar flexors, in both diabetic and age matched healthy individuals, and to identify the impact of these muscles with sit to stand lower extremity functional strength and considering the variables like duration of diabetes, glycemic control, HbA1C values.

   Both the group will be evaluated with five repetition sit to stand test (FRSTST), to screen their lower extremity functional strength, and quality of life measure done through generic health related quality of life measure SF -36 Questionnaire

The main objective of this study is to determine whether a clinical scenario might exist where there will be a subclinical muscle power decrease without any reflections on functions performed in diabetic individuals when compared with age matched healthy individuals.
