Background and Aim: The calculated parameters of the center of pressure (COP) are suitable indicators for evaluating balance in patients after rehabilitation. Therefore, determining the reliability level of each parameter is a matter of great importance. This study tried to determine the reliability of some parameters of the COP sway in patients with myofascial neck pain in different postural situations.

Materials and Methods: The present study is a test-retest reliability design. Twenty patients with myofascial neck pain performed a single and a double leg test with open and closed eyes on a force plate and with open eyes on foam in three sessions with a 30 minute intervals for 30 seconds. Antero-posterior and medio-lateral sway range, mean velocity and mean area of sway were calculated.

Results: The mean velocity showed high reliability (0.98) in all situations, but the other parameters were variable in different situations.

Conclusions: The results showed that some COP parameters are highly reliable in assessment of patients with myofascial neck pain.

Back ground and Aim: Feeding is the most essential behavior in infants for vitality, learning and interaction. Because of feeding importance in developmental process and its primary role in infant’s vitality, the study of dysphagia has an important role. Diagnosis, assessment and treatment of this disorder are primary professional action for speech therapists. Therefore, basic information about prevalence of such disorders can be effective in treatment planning. In this study, the number of infants with oral feeding disorders is determined in NICU .

Materials and Methods: In this descriptive-sectional study, all infants that were in NICU at Tehran University of medical sciences hospitals were evaluated in three first months of 1390 year through information from medical history, interview and observation. The data were analyzed with SPSS 16.

Results: Data analyzing of this study showed that 45 infants (27.10%) from 166 cases in NICU had oral feeding disorders. The incidence in male is more than female (91.11% versus 8.88%). Twenty two of cases feed normally, 18 cases feeding with NGT and 5 cases with OGT. The rate of difficulty in oral phase and esophageal phase were 88.88% and 2.22% respectively. No infants have difficulty in Pharyngeal phase.

Conclusion: Feeding disorder assessment by speech therapist provides essential information about feeding intervention and so early diagnosis can prevent later speech problems. Therefore, the role of a speech therapist in NICU is important.

Background and Aim: Different aspects of the motor control parameters of dominant and non-dominant legs are investigated but the effect of dominancy on motor control strategy is still unclear. The aim of the present study is to compare the pre- motor time, motor time and reaction time in dominant and non- dominant leg muscles of the non- professional healthy athletes in response to visual stimulus during forward jumping.

Methods and Materials: Eleven non- professional healthy athletes participated in this cross-sectional study determined by convenience non probability sampling. Surface electromyography were performed in the dominant and non-dominant leg muscles including  gastrosoleous , peroneus longus, peroneus brevis, and tibialis anterior in response to visual stimulus during forward jumping.

Results: There was no significant difference (P > 0.05) between the dominant and no-dominant legs with respect to the pre-motor time, motor time and reaction time of the gastrosoleus, peroneus longus, peroneus brevis and tibialis anterior.

Conclusion: Our findings suggest that limb dominancy is not an important parameter in the motor control studies.

Background and Aim: Osteoarthrosis is a common condition in the cervical region due to the high mobility of this region. Despite the clinical popularity of traction that is often prescribed for patients with neck pain, there is no agreement on the effectiveness of traction. Due to the high controversy and the lack of experimental documents in the efficiency of the pneumatic traction device in reducing symptoms of neck pain, present study was conducted to evaluate the efficacy of the pneumatic traction device in reducing pain and amount of drug use, and improving disability level in patients with neck osteoarthrosis compared to the control group.

Materials and Methods: Twenty-six patients with neck pain aroused by osteoarthrosis were randomly assigned into two groups of control or experimental. The control group received hot pack, TENS, US, exercise therapy and ergonomic training as their usual physical therapy care. Patients in the experimental group also benefited from the sustained traction via the pneumatic traction device too. All participants were treated for 10 sessions. Pain (NPRS), the level of disability (NDI), the number of sedative drugs and NSAIDs were evaluated in the beginning of the first session and at the end of the last session.

Results: A significant decrease in the levels of the pain and disability in both groups were found (P<0.05). The decrease of pain and disability in the experimental group was significantly higher (P<0.05) than the control group. There was no significant difference in terms of the sedatives and NSAIDs within and between the groups at the end of the last session (P>0.05).

Conclusion: Although physical therapy and ergonomic trainings may lead to a significant improvement in neck pain and related disability in the osteoarthrosis patients, the use of pneumatic traction device can increase the rate of improvement.
