Peroneal nerve palsy secondary to prolonged squatting in seasonal farmworkers.

OBJECTIVE: The aim of this study was to evaluate the follow-up and treatment results of peroneal nerve palsy secondary to prolonged squatting for working and to determine an approach for its treatment and prevention. METHODS: The study retrospectively evaluated 16 patients (7 males, 9 females; mean age: 23.6 years) diagnosed with peroneal nerve palsy due to squatting for work. Clinical and neurological evaluations were performed and weight and height were measured. Lesion site was determined using electrophysiological testing. After diagnosis, medical and orthotic treatment was initiated and rest was advised. Patients were followed until motor symptoms were resolved. RESULTS: Clinical and neurophysiological evaluations were consistent with isolated peroneal nerve palsy. The left side was affected in seven patients, the right side in seven and both sides in two. Average onset of the symptoms was 3.3 (range: 1 to 6) weeks and average daily squatting period was 6.8 (range: 6 to 8) hours. Average healing time was 7.4 (range: 3 to 16) weeks. None of the patients was obese or overweight. All patients healed with conservative treatment and no surgical treatment was necessary. CONCLUSION: Working conditions and duties should be considered in the evaluation of peroneal nerve palsy. In peroneal nerve palsy secondary to squatting, healing should be expected with conservative treatment, resting and close follow-up.
