Cubitus valgus deformity is a medical condition characterized by an abnormal outward angulation of the extended forearm in relation to the arm, typically measured in the frontal plane. What is a Cubitus Valgus Deformity? When the forearm is completely extended, it is inclined away from the body more than usual due to a medical condition…
What is a Genu Recurvatum? The disorder known as genu recurvatum, or knee hyperextension, is characterized by excessive knee joint extension or backward bending beyond its normal range of motion. When standing straight, the lower leg is positioned behind the thigh due to the knee joint’s extension backward. Incidence Congenital genu recurvatum is an uncommon…
What is Rigidity? Rigidity refers to a condition characterized by an increased resistance to passive movement, which remains constant regardless of the position or velocity of the movement. This type of muscular hypertonia is distinct from other forms of muscle stiffness, such as spasticity, where resistance varies with the speed of motion. Many authors use…
What is a Spasticity? One aspect of upper motor neuron syndrome is spasticity, a motor condition characterized by a velocity-dependent increase in tonic stretch reflexes (muscle tone) with heightened tendon jerks as a result of the stretch reflex’s hyperexcitability. Lance’s 1980 physiological definition of spasticity is the most well-known and frequently used explanation of the…
What is Posterior Pelvic Tilt? Posterior pelvic tilt refers to a condition where the pelvis rotates backward, causing the lower back to flatten and the hips to thrust forward. This alteration in pelvic positioning can lead to a cascade of musculoskeletal imbalances and discomfort. Typically, the pelvis is in a neutral position when standing, allowing…
What is Decorticate Posture? A patient in decorticate posture has an abnormal body posture in which their arms are stretched over their chest, their wrists are flexed, their fingers are squeezed and their legs are extended straight forward. The wrists and fingers are bent and rest on the chest, while the arms are bowed inward…
What is Decerebrate Posture? Decerebrate posture, also known as decerebrate rigidity or extensor posturing, is a specific type of abnormal body posture that typically indicates severe damage to the brainstem. It’s characterized by rigid extension of the arms and legs, with the arms positioned straight out and the legs extended and internally rotated. The posture…
What is a Lateral Pelvic Tilt? Lateral pelvic tilt, a common musculoskeletal issue, refers to the asymmetrical positioning of the pelvis in the frontal plane, where one side of the pelvis is higher than the other. This imbalance can lead to various discomforts and dysfunctions in the lower back, hips, and legs, affecting posture and…
What is Anterior pelvic tilt? Anterior pelvic tilt is a postural displacement characterized by the forward rotation of the pelvis, causing the hips to tilt forward and the lower back to arch excessively. When your pelvis is tilted forward, it forces your spine to bend, causing an anterior pelvic tilt. It frequently Causes prolonged sitting…
What is a Mallet Finger? “Mallet finger,” also known as “baseball finger,” is a common injury affecting the extensor tendon of the finger. This injury typically occurs when an object forcefully strikes the tip of a finger, causing sudden flexion of the distal interphalangeal (DIP) joint. An injury to the thin tendon that straightens a…
