Study Notes

Neuromuscular Examination

  • Introduction: The sensory system receives and interprets information from the surrounding environment, including visual, auditory, taste, smell, and somatosensory information.
  • Somatosensory Function: Includes light touch, temperature, pain, vibration, joint position, and discriminative sensation. Loss of this function can impact self-care and injury prevention.
  • Fundamental Concepts: Peripheral receptors in the skin, muscles, ligaments, or joints transmit stimulus information to the spinal cord via afferent nerves. Messages ascend either through posterior columns (for fine touch, vibration, and position) or the spinothalamic tract (for crude touch, pain, and temperature).
  • Spinal Nerve Root Integrity: 31 pairs of spinal nerves exit the spinal cord at intervertebral foramina. Each nerve root has sensory (dermatome) and motor (myotome) components.
  • Dermatomes: Specific areas of skin supplied by a single nerve root. Testing commonly involves light touch.
  • Myotomes: Muscles and muscle groups supplied by a single nerve root. Testing involves assessing strength against resistance.
  • Deep Tendon Reflexes (DTRs): Monosynaptic reflexes, involving one afferent and one efferent component. Evaluated for strength, graded on a scale of 0-4+. Abnormal findings can indicate CNS or PNS damage. Side-to-side differences are significant.
  • Coordination: Involves adequate joint range of motion, strength, neural pathways, and cognitive processing. Cerebellar dysfunction is a common cause of coordination difficulties.
  • Cranial Nerve Assessment: 12 pairs of cranial nerves that emerge from the forebrain and brainstem. Each has unique sensory, motor, or combined functions.
  • Upper Motor Neuron (UMN) Tests: Evaluating for increased muscle tone/spasticity, hyperactive reflexes, and pathological reflexes. Tests include assessing muscle tone (resistance to passive movement), deep tendon reflexes (strength), and pathological reflexes (e.g. Babinski, Hoffmann).
  • Important Considerations: Be aware of individual variation, potential impact of medications, cognitive status, or emotional factors when evaluating coordination, reflexes, or sensation. Professional evaluation and referral are crucial when atypical findings emerge.
