Abstract:

BACKGROUND: Researches on plantar pressure characteristics at home and abroad are focused on ordinary people and patients. The plantar pressure characteristics of migrant workers are rarely reported.
OBJECTIVE: To test the plantar pressure of migrant workers performing frequent physical labor.
METHODS: A total of 30 migrant workers performing frequent physical labor were assigned into migrant worker group. While another 30 university students were assigned into university student group. Dynamic plantar pressures of all the subjects during natural walking were tested by a plate plantar pressure test system (Footscan USB2, Belgium).
RESULTS AND CONCLUSION: The peak pressure of the first toe, the second and third metatarsus in the right foot of migrant workers was significantly higher than that of the university students (P < 0.01). There was no significant difference in foot arch index between the two groups (P > 0.05).The angle of foot deviation and the occurrence of strephenopodia in migrant worker group were larger than that in the university student group during natural walking (P < 0.01). These results demonstrate that frequent physical labor has an obvious effect on plantar pressure distribution in migrant workers. The phenomena include plantar pressure moving forward, increased strephenopodia extent and magnified foot deviation angle during natural walking. Therefore the possibility of lower limb injury becomes more likely.
