Wu Y-Y, Hsu W-C, Wang H-C: Posterior interosseous nerve palsy as a complication of friction massage in tennis elbow. Am J Phys Med Rehabil 2010;89:668–671.
Friction massage is a commonly used physical therapy that is usually safe and without complication. We report an unusual case of posterior interosseous nerve palsy that arose after friction massage. Electrophysiologic findings confirmed a focal neuropathy 4–6 cm distal to the lateral epicondyle. The neurologic symptoms resolved completely 2 mos after discontinuation of friction massage. This case experience broadens the spectrum of etiologies of posterior interosseous nerve palsy. Nerve conduction studies may be a useful adjunct to a thorough physical examination to confirm the diagnosis and is important to prognostic evaluation, if unexplained neurologic symptoms develop after certain physical therapy procedures. Further treatment includes avoiding compression and observation.
