简要总结
The aim of this study was to compare the effect of band tissue flossing method and traditional cuff method for blood flow restriction training on pain, range of motion, muscle strength and functional status in patients with knee osteoarthritis. Symptoms of this condition limit patient's ability to perform high load strengthening. Blood flow restraining training allows strengthening with lower loads. 46 subjects will be divided in two groups, 23 subjects in each group. knee extension and knee press exercises will be performed. In group A floss band was tied on thigh and in group B pneumatic cuff was applied on thigh. 40-60 years individual with knee osteoarthritis will be included. outcome measures will be assessed at baseline, after 1st session, after 2nd week and after 4th week.
详细描述
Osteoarthritis (OA) is a degenerative disorder affecting 528 million people worldwide. It occurs in individuals of age 40 years and above. Most affected joint is knee with prevalence of 60%-85% of total OA cases being 1.39 times higher in women than men. It is characterized by progressive damage to articular cartilage, leading to pain, stiffness, and reduced mobility negatively impacting function and quality of life of affected patients.
Obesity, low level of physical activity, joint overload, muscle imbalance in the knee joint, reduced weight and muscle strength in the lower limbs are the factors which can be modified. Quadriceps strengthening is considered as a first-line therapy making resistance training a common practice in OA management.
A useful alternative to high intensity exercises which are not tolerable by osteoarthritic patients is blood flow restriction (BFR) training. In BFR a cuff is applied around the proximal aspect of the affected limb, causing partial arterial and full venous occlusion, thereby inducing localized hypoxia and the accumulation of metabolites, imitating the effects of high load resistance training without using heavy load and higher repetition. BFR reduces pain along with improving muscle strength, and function in patients with osteoarthritis (OA) and rheumatoid arthritis.
The tissue flossing technique is also called BFR or Kaatsu training. The use of tissue flossing (TF) is a relatively recent treatment modality that gained popularity through the book by Starrett and Cordoza. The mechanisms involved in TF are similar to ischemic preconditioning or BFR training in which an application of an external pressure is used, above or below the muscle or joint, with the application of a tourniquet/inflatable cuff in the most proximal portion of the limb in the case of BFR or an elastic band. Tissue flossing can improve the range of motion or performance, speed up recovery, and decrease the pain caused by various diseases or injuries. The intervention consists of wrapping tissue flossing band around a body region (joint or soft-tissue) using a 50% overlapping in circumferential pattern (distal to proximal), with a relative stretch ranging from 50-75% of the band maximal length, and a treatment duration ranging from 2 minutes to 6 minutes or exercise repetition range from 10 to 30 repetitions.
In 2015, research evaluated effects of BFR on older women and concluded that addition of BFR with resistance training significantly increased leg press or quadriceps strength in older women.

结局指标
主要结局
Numeric Pain Rating Scale (NPRS)
时间窗: 4th week
Changes from baseline will be assessed using NPRS scale. It is a one-dimensional measure of pain severity in adults including those suffering from chronic pain. Scale has ratings of 0 to 10, with higher points indicating higher levels of pain severity. it is a valid tool for assessing pain in knee OA patients.
