Background: Balance is one of the basic needs for daily activities. It has an important role in static and dynamic activities. The purpose of this study is to evaluate the balance of people with peripheral neuropathy after 4-weeks of functional and balance exercise program.

Materials and methods: In this quasi-experimental study, 22 diabetic patients with diabetic peripheral neuropathy (experimental group, n=11 control group, n=11) with the mean age of 53.79 years, mean height of 163.41cm, and mean weight of 71.49 kg, were randomly selected. Berg and T.G.U.G tests were used to evaluate the balance of patients. 12 sessions of combined training (balance and functional training) were used as intervention program. A paired t-test was used for the differences of pre-post test and independent t-tests were used to compare the experimental and control groups.

Results: The paired sample t-test showed that training program has significant effect on functional and dynamic balance. The comparison between the two groups showed no significant deference between pre-functional balance tests and significant post-functional balance test after training program.

Conclusion: Patients with diabetic neuropathy may have an impaired balance. The most important reason is the damage of proprioceptive receptors as combined training (balance and functional training) may improve balance and blood circulation in this organ also putting extra load on the visual system, vestibular and proprioceptive stimulation system and improves balance. Hence, it can be recommended as exercises to improve balance.

Background: Premenstrual Syndrome (PMS) consists of repetitious physical and psychological symptoms that occurs in luteal phase of menstrual period and will be over when menstrual period starts. The goal of this study is to investigate the effect of calcium therapy plus vitamin D and cognitive behavioral therapy (CBT) on the parameters of PMS symptoms in women suffering from PMS.

Materials and Methods: This study has an experimental plan of pretest and post-test of the control group. The statistical society is 250 female staff of Tehran Universities in academic year 2013-2014. Premenstrual syndrome screening tool (PSST) questionnaire was used as an evaluation tool. The collected data were analyzed using the indexes of the descriptive statistics and covariance analysis (p<0.05).

Results: The minimum age of the statistical society was 24, 52.5 % of them held a master's degree and 60% were single. Cognitive behavioral therapy method, calcium and vitamin D therapy were significant in improving the parameters of symptoms at p<0.05 level of significance.

Conclusion: Combining cognitive behavioral therapy and calcium supplementation and vitamin D is significantly effective in improving components of PMS sympotoms and applying these methods is recommended by the consultants and gynecologists.
