A muscle spasm is an involuntary, sudden, and often painful contraction of one or more muscles or muscle groups Primarily affecting the musculoskeletal and neuromuscular systems, spasms can occur in any population and commonly involve the paraspinal musculature, neck, or extremities Pathophysiologically, the condition is characterized by abnormal hyperactivity of motor units, often triggered by acute musculoskeletal strain, mechanical trauma, fatigue, electrolyte imbalances, or underlying nerve ...

Primarily affecting the musculoskeletal and neuromuscular systems, spasms can occur in any population and commonly involve the paraspinal musculature, neck, or extremities

Pathophysiologically, the condition is characterized by abnormal hyperactivity of motor units, often triggered by acute musculoskeletal strain, mechanical trauma, fatigue, electrolyte imbalances, or underlying nerve root irritation Clinically, it manifests as palpable muscle tightness, localized tenderness, restricted range of motion, and occasionally visible twitching or sustained distortion of normal posture
