The frequency domain analysis of ground reaction forces is one of the mechanical parameters that can be distinguished by comparing the differences between healthy and patient groups. The purpose of the current study was to compare the frequency domain analysis of ground reaction forces in deaf and healthy control people during running.

The present study was a quasi-experimental design. A total of 30 male individuals were equally divided into two groups of normal hearing and hearing loss (Deaf group). Peak plantar pressure variables in deaf people and healthy control were recorded using a foot scan system (sample rate: 300 Hz). The multivariate ANOVA test was used to compare the ground reaction force frequency domain data during running in deaf and healthy participants.

The results showed that frequency content with the number of essential harmonies in the Toe area (P= 0.012) and fingers 2 to 5 (P=0.035) in deaf was smaller than that of healthy control group. Also, the frequency content with power of 99.5% in the fourth metatarsal (P=0.038) and fifth metatarsal (P=0.019) in deaf group was greater than that of healthy control ones. Stance time during running was more in deaf group than in healthy control group (P=0.032).

According to the results of the present study, it can be stated that deaf people are likely to be exposed to the damage caused by the ground reaction force frequency domain during running.

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.

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).

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).

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.

Elastic walking with direct involvement of thoracolumbar fascia can prevent from recurrent low back pain. The aim of the present study was to investigate the effect of six weeks of training of elastic walking on the frequency domain of ground reaction forces during running in 10 areas of foot in patients with low back pain. A total of 28 men with low back pain were randomly divided into experimental (n=16) and control (n=12) groups. The participants in the experimental group were trained with elastic walking for six weeks, three days per week, each time for 45 min. Frequency domains of ground reaction forces during both pre- and post-test were recorded using a foot scan system (sample rate: 300 Hz).    The results showed that in experimental group, the number of essential harmonies in the Toe 2 region during post-test was lower than that in the pre-test (P=0.017). The duration of running stance phase during both pre- and post-test were similar in both experimental and control groups (P>0/05). Findings of the present study demonstrated that the effects of elastic gait training on improvement of ground reaction force frequency content in low back patients may have a clinical value during rehabilitation.
