Background: The effect of prolonged occupation-related physical activity can induce stress and strain on the plantar heel pad. These strains can lead to the thickening of the human heel pad.

Methods: The effect of occupation-related physical activity on the thickness of the Heel pad (HPT) was assessed among four classes of occupation- Labourers/farmers, Dancers, Athletes and an inactive class (control/normal group) in a southeast Nigerian population.

Results: Results show that the inactive class had the lowest values for HPT (9.061.26; 9.001.73mm for right and left sides respectively). The athletes had the highest values (15.151.51; 15.181.57mm for the right and left sides respectively). Multiple comparison shows that Labourers, Dancers and athletes had significantly higher values than the control group (P=0.000; 0.036; 0.000 respectively).

Conclusion: Our findings have conclusively established that occupation-related prolonged Physical activity induces thickening of the heel pad. Interventions should be initiated to avoid the setting in of degenerating conditions that may lead to plantar heel pain.
