Effect of Six Weeks Training of Elastic Walking on Frequency Domain of Ground Reaction Forces during Running in 10 Areas of Foot in Patients with Low Back Pain

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.
