Upper limb spasticity

Upper limb spasticity is a sensorimotor disorder characterized by an abnormal, velocity-dependent increase in muscle tone and exaggerated stretch reflexes involving the shoulder, elbow, forearm, wrist, and fingers Arising as a component of the upper motor neuron syndrome, it is caused by central nervous system pathology that disrupts descending inhibitory pathways, leading to disinhibited spinal reflex arcs and neuromuscular overactivity Clinically, it manifests as involuntary muscle contraction...

Upper limb spasticity is a sensorimotor disorder characterized by an abnormal, velocity-dependent increase in muscle tone and exaggerated stretch reflexes involving the shoulder, elbow, forearm, wrist, and fingers Clinically, it manifests as involuntary muscle contractions, painful spasms, and stereotyped posturing—frequently an adducted shoulder, flexed elbow, pronated forearm, and clenched fist—which can lead to progressive joint contractures and substantial impairment of motor function and hy...
