Bilateral Peroneal Nerve Palsy in a Floor Tile Worker Flowing Prolonged Squatting.

Abstract

Peroneal neuropathy is the most prevalent compressive neuropathy of the lower extremity and may result from prolonged squatting. However, bilateral peroneal nerve paralysis following prolonged squatting is uncommon. Squatting-induced common peroneal nerve neuropathy in the workplace has been reported among agricultural workers, sewer pipe workers, and harvesting farm workers, but little is known about this type of neuropathy in other professions. In this report, we present a case of a floor tile worker who, after prolonged squatting for 6-7 hours over two months, developed bilateral lower-leg numbness and weakness due to a bilateral peroneal nerve injury. Two months after cessation of work and physiotherapy, his symptoms and neurophysiological abnormalities had completely resolved. Avoiding prolonged squatting, especially in small spaces, and incorporating knee and knee muscle stretching exercises are highly effective in preventing this neuropathy in workers.
