Key Determinants of Human Posture
Human posture is a dynamic process that depends on the coordinated function of multiple body systems. The central nervous system integrates information from the visual, vestibular, and proprioceptive systems to maintain balance and upright alignment.Normal posture also requires adequate muscle strength, endurance, flexibility, and appropriate muscle tone, particularly in the...

Weak Foot Intrinsic Muscles and Increased Risk of Lumbar PIVD & Low Back Pain
The intrinsic muscles of the foot play a vital role in maintaining the medial longitudinal arch, absorbing ground reaction forces, and providing stability during standing and walking. Weakness of these muscles may lead to excessive foot pronation and collapse of the arch, altering lower-limb biomechanics. These changes can be transmitted...

Chronic Popliteus Muscle Strain and Increased Incidence of Knee Osteoarthritis (OA)
The popliteus muscle is a small but essential stabilizer located at the back of the knee. It helps "unlock" the knee during the initiation of flexion, controls tibial rotation, and contributes to posterolateral knee stability during walking and weight-bearing activities.Chronic strain or tightness of the popliteus muscle may alter normal...

Harmful Effects of Only Doing Quadriceps Exercises in Knee Osteoarthritis
Quadriceps strengthening is an important part of knee osteoarthritis (OA) rehabilitation, but relying on it alone may not provide the best outcomes. Isolated quadriceps exercises, without addressing underlying biomechanical factors, can increase joint compression during certain movements and may aggravate pain in some individuals.Knee OA is often associated with hip...

Foot Arch and Osteoarthritis Knee
The ankle arch plays an important role in protecting the knee joint from excessive stress and reducing the risk of osteoarthritis (OA) knee. A healthy medial longitudinal arch acts as a natural shock absorber and helps maintain proper alignment of the lower limb during standing, walking, and running.When the arch...
