Incidence of and complications of DM has been increased over the last decade. Diabetic polyneuropathy (DPN) plays a significant role in falling among elderly patients because of significantly impaired sensation in the feet and reduced ability to properly control balance during daily activities. The aim of this study was to evaluate the effect of low frequency pulsed magnetic therapy (LFPMT) on balance in patients with DPN. Methods: Thirty male patient with DPN were randomly assigned into two groups G 1 (Study group) and G 2 (Control group). Balance was evaluated pre and post-study using the Biodex Stability System and Short Form of Berg Balance Scale (SFBBS). G 1 was treated with LFPMT for 30 min in session, 3 sessions in a week, for six weeks, while G 2 received identical sham sessions. The results: Pre-study (between groups) comparison revealed that the mean values of the overall stability indices (OSI) were (1.75 ± 0.75, 2.12 ± 0.45) for G 1 and G 2 respectively (P=0.11), the mean values of the SFBBS were (18.8± 3.61, 19.8± 1.93) for G 1 and G 2 respectively (P=0.35). At the end of the study (within groups) comparison revealed that the mean values of the OSI were (1.41 ± 0.78, 2.16 ± 0.7) for G 1 (P=0.02) and G 2 (P= 0.77) respectively, the mean values of the SFBBS were (23.07 ± 3.61,19.6 ±1.18) for G 1 (P=0.00002) and G 2 (P= 0.68) respectively. Post-study (between groups) comparison revealed that there were significant differences in SFBBS (P= 0.002) and OSI (P = 0.01), but in favor of G 1 . Conclusions: LFPMT is an effective therapeutic modality in improving balance in patients with DPN.

The most widely acknowledged psychological change with age is the decline in cognitive processes, especially memory. Balance is achieved by complex integration and coordination of multiple body systems, but most of these systems undergo deterioration as people age, resulting in a decline in the ability of elderly to maintain balance.

Objective: The present study was carried out to investigate the impact of smoking on lung age and ventilatory function in adult Saudi in order to use these effects in a future strategy for smoking cessation. Methods: Eighty one smoker students with their mean age 23.88 ± 2.7 years were enrolled in this study. Every student performed a ventilatory function tests in order to measure lung age, forced vital capacity (FVC), forced expiratory volume at the end of the first second (FEV1), FEV1/FVC ratio and peak expiratory flow rate PEFR.

Methods: Twenty-nine participants of both sexes, between 8 to 12 years of age, participated in this study. They were assigned randomly into 2 study groups. The first group (A) received a chest physical therapy program, while the second group (B) received an aerobic exercise regimen using a rowing ergometer. Vital capacity, forced vital capacity, forced expiratory volume after 1 second, and peak expiratory flow rate were measured before and after 12 successive weeks of treatment. Results: Significant improvements in all measured variables were found posttreatment in both study groups. No significant difference between the 2 groups was found posttreatment. Conclusion: Rowing exercise could be effective in improving pulmonary functions in children with Down syndrome. (Pediatr Phys Ther 2014;26:437-445)

Diabetic foot complications are the most common cause of non-traumatic lower extremity amputation... more Diabetic foot complications are the most common cause of non-traumatic lower extremity amputations in the industrialized world. The risk of lower extremity amputation is higher in diabetics than in persons who do not have diabetes mellitus. Furthermore, foot complications are the most frequent reason for hospitalization in patients with diabetes. Diabetic neuropathy is the impact of diabetes on the nervous system, most commonly causing numbness, tingling and pain in the feet and also increasing the risk of skin damage due to altered sensation. Together with vascular disease in the legs, neuropathy contributes to the risk of diabetes-related foot problems (such as diabetic foot ulcers) that can be difficult to treat and occasionally require amputation. Early detection and appropriate treatment of these ulcers may prevent up to 85 percent of amputations. Purpose: To detect the effect of low mechanical vibration on healing of diabetic foot ulcer. Methods: Twenty nine diabetic patients with type 2 diabetes (21 males and 8 females) suffer from diabetic ischemic foot ulcer (grade A1) will be divided into 2 groups; 1st study group received low mechanical vibration for 15 minutes for session, 3session/day, 5day/week for 4 weeks and control group received no treatment. Assessment of wound size (length, width and area) by Visitrak device for both groups was done 3 times as follow; 1st assessment done before assessment, the 2nd assessment was done 2 weeks after the beginning of treatment and the 3rd assessment was done 4 weeks after beginning of treatment.

A randomized clinical trial was performed on 70 patients with varicose vein of the lower limb. Their age was (40-50) years. Patients were randomly divided into three groups; Group (1) (30 patients) used a contrast bath and compression stocking. Group (2) (30 patients) performed pedal ergometer exercise and the compression stocking. Group (3) (10 patients) used compression stocking. Venous Duplex ultrasound scanning was conducted for evaluating the cross-section of great saphenous vein (CsGSV) at the knee and ankle levels. There was significant reduction in the mean value of CsGSV at the ankle and knee levels in group one and two with non-significant difference in group three. The result revealed a non-significant difference between contrast baths and pedal ergometer exercise groups. Both contrast baths and strengthening exercise to calf muscle are effective methods in the treatment of varicose veins. [Helal OF, Alayat MS, Abdelaal AA.

Laser therapy has a positive effect on bone regeneration and healing that is dependent on the characteristics of the light itself (eg, intensity and wavelength).
