Background Although case reports have identified the presence of distal ulnar nerve sensory and motor dysfunction in long-distance cyclists, the actual incidence of this condition, referred to as “cyclist's palsy,” is unknown. Purpose To determine the incidence of distal ulnar nerve compression in cyclists. Study Design Prospective study. Methods Twenty-five road or mountain bike riders responded to a questionnaire and were then physically examined and interviewed before and after a 600-km… 
The Effect of Long-Distance Bicycling on Ulnar and Median Nerves
Long-distance cycling may promote physiologic changes in the deep branch of the ulnar nerve and exacerbate symptoms of carpal tunnel syndrome.
The Double Crush Syndrome: A Common Occurrence in Cyclists With Ulnar Nerve Neuropathy-A Case-Control Study
A statistically significant greater number of the upper limbs of cyclists with clinical diagnosis of ulnar nerve neuropathy presented with proximal dysfunctions suggestive of double crush syndrome.

Cyclist’s Neuropathy: A Compression Syndrome of the Deep Motor Branch of the Ulnar Nerve A Case Report
A case compression of the deep motor branch of the ulnar nerve as cyclist’s palsy in women learning to ride a bike is reported, owing to the fact that tight grasp in an inappropriate position and hyperextension position of the hand during biking are thought to be the main mechanisms of this lesion type.
Ulnar Neuropathy in Cyclists.
The majority of compression neuropathies in cyclists resolve after appropriate rest and conservative treatment; however, should symptoms persist, nerve decompression may be indicated.
The influence of glove and hand position on pressure over the ulnar nerve during cycling.
The hand pressure magnitudes and loading patterns seen in steady-state cycling are of sufficient magnitude to induce ulnar nerve damage if maintained for long periods, which is both important to mitigate risk for Cyclist's Palsy during extended rides.

Guyon Canal Syndrome: lack of management in a case of unresolved handlebar palsy.
Although treatment for Guyon Canal Syndrome can be as easy as cessation from cycling until symptoms subside, other treatment options could be utilized to help manage ulnar nerve compression injuries in cyclists.
Ulnar Tunnel Syndrome (Guyon Canal)
Treatment consists first of nonsurgical management; however surgical decompression may be warranted for failure of nons surgical treatment or for persistent and/or worsening symptoms.


Cyclist's palsy Neurological and EMG study in 4 cases with distal ulnar lesions
Four cases of cyclist's palsy -- a distal compression syndrome of the ulnar nerve which can develop after long cycling tours -- are described and it is demonstrated that a functionally significant paresis of the hand muscles can persist for several months.
Distal sensory latencies of the ulnar nerve in long distance bicyclists: pilot study*.
Results of this study lead to the belief that there may be adaptive changes in long distance cyclists which could account for changes in sensory nerve conduction velocity of the ulnar nerve.
Ulnar nerve compression at the wrist. Ulnar tunnel syndrome.
Patients with type 2 syndrome usually present late because of the lack of sensory changes, and the term "ulnar tunnel syndrome" is encouraged to discuss these lesions and the classification outlined by Shea to determine the site of the lesion.

A patient who had bilateral neuropraxia of the ulnar nerve following a 5-day bicycle ride across the Swiss Alps is described to familiarize the hand therapist with "cyclist's palsy" and to illustrate how the recovers of both nerves were followed using manual muscle strength testing and dynamometry.
Compressive mononeuropathy of the deep palmar branch of the ulnar nerve in cyclists.
Two cyclists developed mononeuropathy of the deep palmar branch of the ulnar nerve due to ulnar nerve compression adjacent to the ulnar tunnel (of Guyon) by prolonged bicycle riding. A modification
Handlebar problems in bicycling.
Handlebar problems are common among serious bicyclists and mechanical and medical management are effective in relieving symptoms and preventing recurrence.
Ulnar neuropathy in bicycle riders.
Three patients, one of whom is described in detail, developed ulnar neuropathy following prolonged bicycle riding, with compression of the ulnar nerve at the level of the ulnar canal at the wrist.

Hazards of bicycling: from handlebars to lightning.
Four areas of bicycle trauma that frequently brings the bicycle patient to the attention of a neurologist are chosen: head trauma as a consequence of road collisions; compressive ulnar neuropathy; impotence, probably due to compression of the pudendal nerve or its branches; and lightning-related bicycle injuries.
