BackgroundMultiple Sclerosis (MS) is a disease of the central nervous system that results in many symptoms including mobility limitation and fatigue.Patients and MethodsThirty-one MS patients, all female with mean of age of 36.75 years and Expanded Disability Status Scale scores (EDSS) of 1.0 to 4.0 were recruited. Subjects were randomly assigned to one of the three groups: treadmill training, yoga or control groups. Treadmill training and yoga practice consisted of 8 weeks (24 sessions, thrice weekly). The control group followed their own routine treatment program. Balance, speed and endurance of walking, fatigue, depression and anxiety were measured by Berg Balance scores, time for 10m walk and distance for a two minute walk, Fatigue Severity Scale (FFS), Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI), respectively.ResultsComparison of results have shown that pre- and post-interventions produced significant improvements in the balance score, walking endurance, FFS score, BDI score and BAI score in the treadmill training group and yoga group. However, 10m walk time decreased in the treadmill training group but did not show any clear change in the yoga group. Moreover, the analysis showed significant differences between the treadmill training group and yoga group for BAI score.ConclusionsThese results suggest that treadmill training and yoga practice improved ambulatory function, fatigue and mood status in the individuals with mild to moderate MS.

The Persian version of Tegner and Marx seems to be suitable for Iranian patients with ACL injury. Future studies are needed to investigate the psychometric properties of these questionnaires for Iranian patients with different knee problems.

To compare the effects of single- versus dual-task balance training on the gait smoothness and balance of community-dwelling older adults, 69 volunteers were randomized to single-, dual-task training, and control (no intervention) groups. Exercises were received in 18 sessions through 6 weeks. The gait smoothness was measured by the harmonic ratio of trunk accelerations using a triaxial accelerometer. Balance performance was assessed through the Fullerton Advanced Balance scale, Timed Up and Go test, Activities-specific Balance Confidence, and gait speed. After the trial, all variables improved significantly in the training groups. Moreover, differences in the mean change of all variables, except the Timed Up and Go test, were statistically significant between the interventional groups and the control group, but no significant difference was reported between the two training groups. This study suggests that balance training can improve gait smoothness as well as balance status in healthy older adults.

Adoption of the insole improved the design of the shoe-foot interface support for the flexible flatfoot athletes, enabling them to develop more effective take-off kinetics for vertical jumping in terms of ground reaction force and stance duration similar to that of normal foot subjects without insole.

To clarify the significance of mechanical impairments, pain, and functional limitations as predictors of chronic low back pain (LBP). Ninety patients with chronic nonspecific low back pain (CNSLBP) were prospectively studied with clinical tests and questionnaires. Changes in muscle extensibility and endurance tests were evaluated and changes assessed in LBP intensity on numeric rating scale 0–10 and severity with Oswestry Disability Index (ODI) 0–100. In the present study we found significant associations between the 4 muscle extensibility and 2 endurance tests and pain at nonspecific patients with chronic LBP (P<0.005). The 2 muscle extensibility and 1 endurance tests were in complete equilibrium with ODI disability and hence showed similar results (P<0.005). The associations between the muscle extensibility and endurance tests and pain were significantly elevated in patients with nonspecific chronic LBP.

The Persian version of the CDS can help clinicians and nurses to assess patients' need and the degree of care dependency among older adults in Persian-speaking areas.
