Question

which result of the bicycle test is consistent with neurogenic claudication?
○ symptoms worsen when pedaling in a flexed position
○ leg pain persists regardless of posture
○ no change in symptoms with pedaling
○ symptoms improve when pedaling in a flexed position

Explanation:

Neurogenic claudication stems from spinal stenosis, where spinal canal narrowing compresses nerve roots. A flexed posture (like leaning forward while pedaling a bicycle) widens the spinal canal, reducing nerve compression and thus improving associated symptoms. Other options do not align with this key pathophysiological response.

Answer:

Symptoms improve when pedaling in a flexed position
