Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This study will be conducted to compare the effect of BFR with LLRT versus neuromuscular training on quadriceps muscle strength, knee joint function and proprioception accuracy.
BACKGROUND:
Patients with knee OA may have reduction of tolerance of the high-load programs which is recommended for eliciting strength gains (Messier et al., 2013). Thus, for reducing disease risk and enhancing physical function, there is a need for effectively strengthening the quadriceps muscle while limiting pain and adverse joint loading in people with knee OA (Segal et al., 2015). Blood flow restriction (BFR) with low-load resistance training (LLRT) is an alternative to traditional strength training that can be used in knee OA with minimal adverse joint loading that is normally found in traditional strengthening programs(Pope et al., 2013). It is attained through applying pressure externally with a pneumatic cuff or tourniquet. The applied pressure occludes venous outflow while maintaining arterial inflow with intent to promote blood pooling in the capillary beds of the limb muscles distal to the tourniquet (Slysz et al., 2016). Kubota et al., (2008), showed that BFR can be applied during periods of immobilization to decrease disuse muscle atrophy of limbs. Also it can be combined with exercise which enhances muscular development. Resistance exercise appears to provide great muscular gains when combined with BFR (Slysz et al., 2016).
HYPOTHESES:
1. There will not be a significant difference between traditional training, BFR with LLRT and neuromuscular training on improving quadriceps muscle strength using HHD in patients with unilateral knee OA.
2. There will not be a significant difference between traditional training, BFR with LLRT and neuromuscular training on improving knee joint function on WOMAC questionnaire in patients with unilateral knee OA.
3. There will not be a significant difference between traditional training, BFR with LLRT and neuromuscular training on improving knee joint proprioception in patients with unilateral knee OA.
RESEARCH QUESTION:
Does blood flow restriction with low load resistance training and neuromuscular training have a significant effect over traditional rehabilitation protocol (stretching and strengthening for hip and knee muscles) on quadriceps muscle strength, knee joint function and proprioception accuracy in patients with unilateral knee OA?
