Knee Flexion and Extension: What Is It? Knee flexion and extension are fundamental movements that play a crucial role in our daily activities, from walking and running to sitting and standing. These movements involve the bending (flexion) and straightening (extension) of the knee joint, which is one of the largest and most complex joints in…
Definition Deep Tendon Reflexes (DTRs) are involuntary, automatic responses to a stimulus applied to a tendon, typically involving the muscle it is connected to. These reflexes are essential for assessing the integrity of the nervous system, particularly the motor and sensory pathways. When a typical person taps a muscular tendon vigorously, the two-neuron reflex arc…
Introduction: A critical procedure that is necessary for the knee’s ultimate extension is the locking and unlocking mechanism of the joint, often known as the “Screw home mechanism (SHM)”. An individual with a locked knee may find it difficult to bend or straighten their leg for extended periods. This ailment might be chronic or uncommon….

Isometric exercise, often referred to as static strength training, is a form of physical activity where muscles are contracted without changing their length. Unlike traditional resistance training exercises that involve movement, isometric exercises involve holding a position against resistance. These exercises can be performed using body weight, resistance bands, or even everyday objects like walls…
What is a Pain Gate Mechanism? The pain gate mechanism, proposed by Melzack and Wall in 1965, revolutionized the understanding of pain perception and management. This theory elucidates how the central nervous system modulates and regulates pain signals, influencing an individual’s perception of pain intensity. The concept of the pain gate mechanism suggests that the…
