Spinal cord lesions have various aetiologies, and trauma is one of the leading causes. Patients with spinal cord injuries (SCI) often have motor, sensory and autonomic dysfunctions and require a multidisciplinary rehabilitation pro gramme. In this study 1694 SCI patients were investigated, including the frequency, and the distribution by age, sex, profession, aetiology, clinical status and year of occurrence. Traumatic SCI is more frequent among males than females and among those between the ages of 15 and 39 years. Regarding the aetiology, traffic accident comprised 35.41% of the total cases, the second most common cause was falls with 29.51%, and the third was high velocity bullet wounds: 21.95%.
This study aimed to investigate the acute effects of exercise on bone turnover and to determine whether brisk walking with or without weight-lifting makes a difference on bone metabolism. Nine healthy women performed two exercise bouts: brisk walking on a treadmill for 30 min (E), and similar exercise carrying 5 kg of weight in a backpack (WE). Serum parathyroid hormone (PTH), osteocalcin (OC), calcitonin (CT), procollagen type 1 carboxy terminal propeptide (PICP), procollagen type 1 amino terminal propeptide (PINP), type 1 collagen carboxy terminal telopeptide (ICTP), total alkaline phosphatase (ALP), and urine deoxypyridinoline (D-Pyr) levels were studied. Resting values served as control. Significant variances were observed only in serum ALP and PTH values. Variances in ALP values within subjects after exercise were statistically significant (analysis of variance in repeated measurements [AVRM], P=0.000). E caused a significant decrease, while WE caused a significant increase in ALP values at the 24th h (Bonferroni pairwise comparisons tests [BPC t-test]: P=0.028, P=0.000, respectively). Variances in PTH values within subjects after exercise were statistically significant (AVRM, P=0.029), while diurnal variation was not significant (P=0.981). E caused significant alterations in PTH levels (an increase at the 30th min, turned towards baseline at the 45th min) (BPC t-test, P=0.007). WE also caused alterations in PTH levels, though insignificant (BPC t-test, P=1.00). Brisk walking for 30 min has stimulating effects on bone turnover by various mechanisms without any additive effect of weight bearing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
