Abstract

Background and Aims: The Frequency Domain analysis of Ground reaction forces is one of the mechanical parameters that play a significant role in the vulnerability of people while walking and running. The purpose of the present study was to compare the frequency domain analysis of ground reaction forces in deaf and healthy control people during running.
Materials and Methods: A quasi-experimental study was carried out on 30 males who were equally divided into a healthy group and a group with hearing loss problems (Deaf group). Peak plantar pressure variables in deaf individuals and healthy controls were recorded using a foot scan system (sample rate: 300 Hz).
Results: The results showed that the frequency content with the number of essential harmonies in the Toe foot (p= 0.012) and foot finger 2 to 5 (p=0/035) in deaf were smaller than those of the healthy controls. Also, the frequency content with power 99.5% in the fourth metatarsal (P=0.038) and fifth metatarsal (P=0.019) in deaf were greater than those of the healthy controls. Moreover, stance time during running in deaf group was more than that of the healthy control group (p=0.032).
Conclusion: Stance time during running in deaf group was more than that of the healthy control group, which has the potential for injury in these people.
