<p><strong>Purpose: </strong>The objective of the study is to evaluate the effects of exercise on balance function with people who have Type 2 diabetes. <strong>Methods: </strong>The subjects in the study were 26 patients with Type 2 diabetes exercise regularly and 27 patients with Type 2 diabetes who do not exercise. The two groups were compared  based on the following: the  fall index (FI), the low frequency of Fourier transformation (F1, F2) under natural standing on solid surface with eyes opened,the frequency of Fourier transformation (F1, F2, F5, F6)under Standing on the soft mat with eyes opened（PO），the high frequency of Fourier transformation (F5, F6) under natural standing on solid surface with eyes closed (NC)，the frequency of Fourier transformation (F3, F4)under natural standing on solid surface with eyes closed and head turn to right(HR). <strong>Results</strong>: The fall index (FI), the frequency of Fourier transformation (F1, F5, F6)under Standing on the soft mat with eyes opened（PO）,the high frequency of Fourier transformation（F6) under natural standing on solid surface with eyes closed(NC) were statistically different for the two groups. The other parameters have no significant differences. The balance function of patients who exercise regularly were better than those who don’t exercise.</p>

ing joints are still existing rigid a year after fracture [3], ankle fractures and surgical treatment seriously affect the stability of the patients' body posture [4], so the primary goal of the treatment of ankle fracture is recovery the affected joint motion .Postoperative rehabilitation include promoting blood circulation, promote healing of soft tissue and fractured union, strengthen the lower limb muscle strength, restore limb function, increase the lower limb coordination, restore ankle weight-bearing walking ability [5], proprioception and the balance training played an important role in the process of rehabilitation, balance training has positive effect in improving clinical outcomes and also improve the quality of life of patients. Purpose of this study is to evaluate the balance ability of patients with ankle fracture, provides some references to patients for postoperative rehabilitation training. KEYWORDS Ankle fracturesBalance Rehabilitation ABSTRACT Objective: The objective of the study is to evaluate the balance disorders in patients with surgical treatment of ankle fractures with the use of Sunlight Tetrax. Methods: The subjects in the study were 20 patients with ankle fractures treated surgically (after six months of the procedure) and the control group comprised 21 healthy subjects. Two groups compare the general stability index (ST), the high frequency of Fourier transformation (F5-F6), the body weight distribution index (WDI) ,synchronicity of foot under natural standing on solid surface with eyes opened and natural standing on solid surface with eyes closed and the fall index (FI). Results: The fall index (FI) and the stability index (ST) under natural standing on solid surface with eyes opened of two groups were statistically significant differences. The balance of patients with ankle fracture after 6 months with surgical procedure is significantly poorer than healthy subjects.
