Study on Red Flags • Overall, 11 of 1172 (0.9%) patients were confirmed as having a serious spinal condition, including spinal fracture (n = 8), caudaequina syndrome (n = 1), or inflammatory disorder (n = 2). • No patients were identified with cancer or infection as the cause of their pain. • For spinal fractures, the diagnostic accuracy of the following red-flag questions was determined: (1) age > 70 years, (2) significant trauma, (3) prolonged corticosteroid use (duration not defined), and (4) altered sensory level (from the trunk down).
Temperature • Viscosity • NCV – increase with heat • Blood flow – heat increases • Collagen extensibility – heat increases tendon and collagenase activity is increased
Heat uses are • hyperemia • analgesia • hyperthermia • decrease muscle tone • increase in collagen elasticity
Heat Therapy • Chronic • Proximal • Reduce muscle spasms • Pain reduction • Reduce stiffness and contractures • Arthritis • Chronic inflammation
Contraindications to Heat • Ischemia (10% increase in skin temp there is 100% increase in metabolic demand) • Bleeding disorders • Impaired senation • Inability to communicate or respond to pain • Malignancy • Acute trauma or inflammation • Scar formation
