The application of different forefoot pads is supposed to result in the changes of the foot pressure at two different tasks. The different density materials of forefoot pads are designed to displace pressure on feet, but the influence on foot pressure at different tasks is not clear. This study can offer the information for the application of metatarsal pads at different functional tasks. Methods:There were five college male students recruited in this study to perform the tasks of running at 7.2 km per hour and walking at 4.2 km per hour randomly. After ten minutes of tasks, the plantar pressures at different forefoot pads were collected by the Medilogic Foot Pressure Insole-System for one minute. The data of forefoot mean pressure, mean maximum pressure, centre of pressure (COP) displacement during running and walking were recorded for analysis. The student t test was used to examine the difference among the different insoles and functional tasks. The level of significance was α=0.05. Results &Discussion:Generally, no significant findings were reported due to the small case number, but the tendencies of changes were observed. The mean pressure at forefoot was found less in the insoles combined softer-release pads than the hard-release pads. The insoles combined softer-release pads also showed less mean pressure than with insole only during running. The higher mean maximum forefoot pressure at insoles added hard-release pads were demonstrated either at walking or running during the treadmill test, and the less ones were showed at insoles added softer-release pads at all tasks. The decrease of COP displacement was showed at the insoles with both foot pads at the two different movement patterns. Conclusion:The softer-release pads contribute to the forefoot mean pressure distribution, the forefoot maximum pressure release and to stabilize the COP trajectory at the two movement patterns.
