Upper limb nerve entrapments in elite wheelchair racers.
The prevalence of upper limb nerve injuries has been reported to be as high as 73% in individuals who rely on manual wheelchairs for mobility.
Many authors hypothesize that the repetitive trauma to carpal canal structures caused by propelling a wheelchair is the reason for this high prevalence.
The purpose of this study was to determine the prevalence of nerve conduction abnormalities in a group of elite wheelchair racers whose wrists are exposed to additional propulsion-related trauma during training and competition.
We performed bilateral upper limb nerve conduction studies on each athlete (n=12).
The racers pushed their chairs an average of 56 miles a week for training purposes.
Fifty percent of the athletes (n=6) had evidence of median mononeuropathy by nerve conduction.
Of these 6 racers, 5 had evidence of mononeuropathy bilaterally, making a total of 11 positive hands of the 23 tested.
Twenty-five percent of the athletes had evidence of ulnar mononeuropathy at the wrist, and 25% had evidence of ulnar mononeuropathy at the elbow.
Seventeen percent of athletes had evidence of radial nerve injury.
Years with a disability accounted for a significant amount of the variance in the mean median sensory amplitude (R2=0.511 ; P=0.020) and the mean ulnar palmar amplitude (R2=0.605 ; P=0.008).
Variables not correlated with nerve conduction studies include age, hours per day in a wheelchair not spent training, years competing, and number of miles pushed in training. (...)
