Document Summary

Hemodynamic effects - decreased blood flow in area of cooling: vasoconstriction of cutaneous blood vessels, dorsal root ganglion stimulation. Peripheral nerve effects: slows nerve conduction velocity. Muscle performance effects: short periods (5 min) increase strength, prolonged cooling (30 min) decrease, extreme cold can block nerve strength conduction, risk of nerve injury or damage. Proprioceptive effects: decreases ability to locate joint in space. Neuromuscular effects: temporary reduction in spasticity associated with cns lesions, temporary decrease in amplitude of dtrs, decreased frequency, duration, and threshold of clonus. Primary goals: limit edema formation, reduce pain, facilitate muscle relaxation, limit secondary hypoxic tissue injury. Clinical applications: acute inflammatory stage, musculoskeletal trauma, myofascial pain syndrome, reduction of spasticity. Cold packs: cold packs, ice massage, controlled-cold compression units, convection, evaporation. Indications: acute phase of soft tissue injury, decrease inflammation (up to 72 hours post injury) Increased pain threshold (analgesic: reduce edema, decreased muscle spasm, decrease spasticity (neurological patient, treat myofascial trigger points (vapocoolant spray)
