Abstract
Background: It has been shown that five deficits of the proprioceptive system and poor motor skills are associated with chronic low back pain (CLBP). However, the exact mechanism is unknown. The objectives of this study were to assess the dynamic postural balance behavior of CLBP patients, as well as the effects of a specific exercise therapy for the treatment of CLBP and related postural imbalances.
Methods: Sixteen females with CLBP and 30 healthy females all between 20 and 40 years of age, of similar height and weight, voluntarily participated in this study. Patients underwent a three-month therapeutic exercise program. The disability and back pain of the patients were measured using the Oswestry and Quebec questionnaires, respectively. A dynamic stability platform system (Biodex) was used to evaluate the postural imbalances in both groups. All measurements of the experimental group were repeated after the therapy.
Results: Overall deviation of center of gravity (COG) from COBOS in patients and controls were 3 (±0.3) and 1.3 (±0.2), respectively. Thus, postural imbalances were 2.3 times greater in the patients than those of the controls. After the treatment, the disability and pain of the patients were diminished by 53% and 58%, respectively. Furthermore, with the improvement of the patients COG deviation, both groups had similar posture.
Conclusions: The postural orientation of CLBP patients was significantly improved by the therapeutic exercise program. The applied exercise therapy significantly reduced both the pain and the disability of the patients. Based on these conclusions, we recommend that postural correction be included in regular therapeutic exercise programs.

Abstract
Background: Gastroesophageal reflux is a common condition among premature infants, which causes problems such as reduced weight gain and prolonged length of hospital stay. Body status is an appropriate way to reduce this condition. However, there have been few studies conducted in this regard. The objective of this study was therefore to investigate the effect of body status on gastroesophageal reflux in premature infants.
Methods: The present research was a crossover study conducted on premature infants with a gestational age of 33-36 weeks in Al-Zahra Hospital in Tabriz, Iran, from January to March 2015. In this clinical trial, thirty-two premature infants hospitalized in this center were selected as the sample. The initial selection of the participants was based on the simple random sampling. Then the participants were allocated to groups using randomized block procedure. Each infant was under study for 4 days. After each feeding and about two hours before the beginning of next feeding, the infants were randomly and not repeatedly put in one of the following four status for 12 hours (8 am -8 pm) every day: facilitated fetal tucking posture in lateral position, free body posture in lateral position, facilitated fetal tucking posture in supine position, and free body posture in supine position. Then, the incidence of gastroesophageal reflux was measured in each of these statuses. SPSS software, version 21 (SPSS Inc., Chicago, IL, USA) was used to analyze the data at significant level of P<0.05.
Results: The results showed that there was a significant difference between facilitated fetal tucking posture in lateral position and other status (P<0.001). The incidence of gastroesophageal reflux in facilitated fetal tucking posture was lower than free body posture, but there was no statistically significant difference in this regard. Moreover, the incidence of reflux in lateral position was significantly less than those in supine position (P=0.04).
Conclusion: The findings of this study revealed that facilitated fetal tucking posture and lateral positioning reduced the incidence of gastroesophageal reflux in hospitalized premature infants.
