In a report presented at the annual scientific meeting of the American Association of Electrodiagnostic Medicine in Savannah, Georgia, authors described the case of a 62-year old, right handed, male amateur golfer with nerve damage in his left hand they attributed to improper grip technique. The report authors, Mayo Clinic neurologists Dr. K. Boylan, W. D. Freeman and B. H. Eidelman, and neurosurgeon R. E. Wharen, used this case to illustrate an under recognized cause of a particular type of nerve damage—ulnar neuropathy—in golfers.

The patient's golf grip applied pressure from the end of the club directly over Guyon's canal in the left hand. Guyon's canal is a passageway between bones of the hand through which the ulnar nerve passes.

The golfer presented a 2-month history of muscle weakness and loss of sensation in his left hand. Electrodiagnostic testing (EDX) confirmed the presence of muscle and nerve damage and magnetic resonance imaging of the left hand was normal.

The golfer was advised to cease golfing for a period of observation, but the patient modified his golf grip and continued playing. After 6 weeks, clinical and EDX findings were improved. He continues to play golf and recovered fully.

"This patient," stated Boylan, "illustrates how golfers can injure themselves by using improper golf technique. Our informal survey of local golf professionals suggests lack of awareness of the potential for this type of injury."

Boylan noted that, fortunately, golfers can easily prevent this condition by using a proper golf grip. He also suggested the need for increased awareness among neuromuscular specialists in recognizing this treatable condition.

The AAEM is the largest organization worldwide (approximately 5000 members) dedicated to advancing neuromuscular, musculoskeletal, and electrodiagnostic medicine. The primary goal of the AAEM is to increase the quality of patient care, specifically for those patients with disorders of the central and peripheral nervous systems, neuromuscular junction, and skeletal muscles. This is accomplished through programs in education, research, and quality assurance. The AAEM believes that only physicians trained in electrodiagnostic procedures should perform needle electromyography and interpret nerve conduction studies to assure patients receive the proper diagnosis.
