Abstract
The present pilot study investigates the impact of a Faroese chain dance intervention on health profile, mobility, and postural balance in elderly subjects. Healthy elderly subjects (n=27; age 75 ± 5 yrs) were randomised into an intervention group (IG) and a control group (CG). IG performed twice-weekly sessions of Faroese chain dance over 6 weeks. Dancing sessions lasted 30 min in the initial 3 weeks and 45 min in the final 3 weeks. Health profile was determined before and after intervention by measuring blood pressure, resting heart rate, muscle mass, and body fat content. Postural balance was evaluated using the Berg Balance Scale (BBS) and Fullerton Advanced Balance Scale (FAB) tests, while mobility was assessed using the Short Physical Performance Battery (SPPB), the Timed Up & Go (TUG) test, the 6-min walk test, and the 30-s sit-to-stand test. Systolic and diastolic blood pressure were lowered (9 ± 6 and 6 ± 3 mmHg, respectively) in IG, with a tendency (P=0.07) for a greater change score than in CG. Mean arterial pressure declined (P<0.05) by 7 ± 3 mmHg in IG, which tended (P=0.09) to be greater than in CG. IG improved (P<0.05) on BBS and FAB scores by 3.6 ± 2.1% and 15.8 ± 8.3%, with the change score for FAB being greater (P<0.05) than in CG (0.3 ± 1.6). Moreover, the postintervention SPPB score was improved (P<0.05) more in IG (13.9 ± 7.4%) compared to CG, while performance in the 30-s sit-to-stand, 6-min walk, and TUG tests improved (4-15%; P<0.05) in IG only. Body fat content was reduced (P<0.05) from 36.3 ± 2.8% to 34.8 ± 2.8% in IG, with no between-group differences and no change in CG (34.1 ± 2.8% to 33.7 ± 3.1%). In conclusion, a 6-week Faroese chain dance programme lowers blood pressure and improves postural balance and physical function in elderly.

Abstract
BACKGROUND Vitamin D supplement use is recommended best practice in residential aged care facilities (RACFs) for the prevention of falls, however has experienced delays in uptake. Following successful international efforts at implementing this evidence into practice, the ViDAus study sought to replicate this success for the Australian context. The aim of this paper is to report on the process outcomes of implementing this intervention. METHODS Forty-one RACFs were engaged in a multifaceted, interdisciplinary knowledge translation intervention. This focused on raising awareness to improve knowledge on vitamin D, and supporting facilities to identify barriers and implement locally devised strategies to improve the uptake of evidence based practice (EBP). RESULTS Staff members of participating facilities (n = 509 including nursing, care and allied health staff) were well engaged and accepting of the intervention, though engagement of servicing general practitioners (GPs) (n = 497) and pharmacists (n = 9) was poor. Facilities each identified between three and eight strategies focused on raising awareness, identifying residents to target for vitamin D and creating referral pathways depending upon their own locally identified barriers and capacity. There was variable success at implementing these over the 12-month intervention period. Whilst this study successfully raised awareness among staff, residents and their family members, barriers were identified that hindered engagement of GPs. CONCLUSIONS The intervention was overall feasible to implement and perceived as appropriate by GPs, pharmacists, facility staff, residents and family members. More facilitation, higher-level organisational support and strategies to improve RACF access to GPs however were identified as important improvements for the implementation of vitamin D supplement use.

Abstract
BACKGROUND Individuals with stroke are at significant risk of falling. Trip-specific training is a targeted training approach that has been shown to reduce falls in older adults and amputees by enhancing the compensatory stepping response required to prevent a fall. Still, individuals with stroke have unique deficits (e.g. spasticity) which draws into question if this type of training will be effective for this population. OBJECTIVE Evaluate if a single session of trip-specific training can modify the compensatory stepping response (trunk movement, step length/duration, reaction time) of individuals with chronic stroke. METHODS Sixteen individuals with unilateral chronic stroke participated in a single session of trip-specific training consisting of 15 treadmill perturbations. A falls assessment consisting of 3 perturbations was completed before and after training. Recovery step kinematics measured during the pre- and post-test were compared using a repeated measures design. Furthermore, Fallers (those who experienced at least one fall during the pre- or post-test) were compared to Non-fallers. RESULTS Trip-specific training decreased trunk movement post perturbation. Specifically following training, Trunk flexion was 48 and 19 percent smaller on the small and medium perturbations at the end of the first compensatory step. Fallers (9 out of 16 subjects) post-training resembled Non-Fallers pre-training. Specifically, Trunk flexion at the completion of the first step during small and medium perturbations was not different between Fallers post-training and Non-Fallers pre-training. Still enthusiasm was tempered because Trunk flexion at the largest perturbation (where most falls occurred) was not changed and therefore total falls were not reduced as a result of this training. SIGNIFICANCE Our results indicate that trip-specific training modifies the dynamic falls response immediately following trip-like treadmill perturbations. However, the incidence of falls was not reduced with a single training session. Further study of the implications and length of the observed intervention effect are warranted.

Abstract
OBJECTIVES To examine the effect of functional impairments in older women with diabetes mellitus (DM) on incident clinical fractures. DESIGN Secondary analysis of two large prospective cohort studies. SETTING North Carolina Established Populations for Epidemiologic Studies of the Elderly (EPESE) and Women's Health Initiative (WHI) clinical trials. PARTICIPANTS EPESE included 2,704 community-dwelling women aged 65 and older; WHI clinical trials included 68,125 postmenopausal women. MEASUREMENTS Women with DM at baseline were compared with women without in successive Cox proportional hazards models. Functional limitations were determined according to self-reported difficulties with activities of daily living (ADLs) and physical activities. RESULTS The risk of any clinical fracture during the study period was greater in women with DM, after controlling for age, race and ethnicity, and body mass index, in the EPESE (hazard ratio (HR) = 1.36, 95% confidence interval (CI) = 1.08-1.72) and WHI (HR = 1.29, 95% CI = 1.19-1.39) cohorts. After inclusion of functional limitations, the greater risk of fracture associated with DM decreased in the EPESE (HR = 1.25, 95% CI = 0.98-1.59) and WHI (HR = 1.21, 95% CI = 1.12-1.31) cohorts. In participants with DM, difficulties with moderate physical activities, such as bending or stooping, walking several blocks, and heavy housework, were significantly associated with incident fracture (P < .05). CONCLUSION Older women with DM are at greater risk of clinical fractures than those without, independent of bone mineral density. Greater functional impairment in moderate physical activities mediates this greater fracture risk in part, although there remains an unexplained residual DM-associated risk for fracture.

Prevention of falls and fractures in old people by administration of calcium and vitamin D, randomized clinical trial.
López-Torres Hidalgo, J, ,
BMC public health. 2011;:910
Abstract
BACKGROUND There are many studies that associate vitamin D serum levels in older persons with muscle strength, physical performance and risk of fractures and falls. However, current evidence is insufficient to make a general recommendation for administrating calcium and vitamin D to older persons. The objective of this study is to determine the effectiveness of calcium and vitamin D supplementation in improving musculoskeletal function and decreasing the number of falls in person aged over 65 years. METHODS/DESIGN Phase III, randomized, double blind, placebo-controlled trial to evaluate the efficacy of already marketed drugs in a new indication. It will be performed at Primary Care doctor visits at several Healthcare Centers in different Spanish Health Areas. A total of 704 non-institutionalized subjects aged 65 years or older will be studied (sample size calculated for a statistical power of 80%, alpha error 0.05, annual incidence of falls 30% and expected reduction of 30% to 20% and expected loss to follow up of 20%). The test drug containing 800 IU of vitamin D and 1000 mg of calcium will be administered daily. The control group will receive a placebo. The subjects will be followed up over two years. The primary variable will be the incidence of spontaneous falls. The secondary variables will include: consequences of the falls (fractures, need for hospitalization), change in calcidiol plasma levels and other analytical determinations (transaminases, PTH, calcium/phosphorous, albumin, creatinine, etc.), change in bone mass by densitometry, change in muscle strength in the dominant hand and change in musculoskeletal strength, risk factors for falls, treatment compliance, adverse effects and socio-demographic data. DISCUSSION The following principles have been considered in the development of this Project: the product data are sufficient to ensure that the risks assumed by the study participants are acceptable, the study objectives will probably provide further knowledge on the problem studied and the available information justifies the performance of the study and its possible risk for the participants.If calcium and vitamin D supplementation is effective in the prevention of falls and fractures in the elderly population, a recommendation may be issued with the aim of preventing some of the consequences of falls that affect quality of life and the ensuing personal, health and social costs.

Abstract
Specific receptors for vitamin D have been identified in human muscle tissue. Cross-sectional studies show that elderly persons with higher vitamin D serum levels have increased muscle strength and a lower number of falls. We hypothesized that vitamin D and calcium supplementation would improve musculoskeletal function and decrease falls. In a double-blind randomized controlled trial, we studied 122 elderly women (mean age, 85.3 years; range, 63-99 years) in long-stay geriatric care. Participants received 1200 mg calcium plus 800 IU cholecalciferol (Cal+D-group; n = 62) or 1200 mg calcium (Cal-group; n = 60) per day over a 12-week treatment period. The number of falls per person (0, 1, 2-5, 6-7, >7 falls) was compared between the treatment groups. In an intention to treat analysis, a Poisson regression model was used to compare falls after controlling for age, number of falls in a 6-week pretreatment period, and baseline 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D serum concentrations. Among fallers in the treatment period, crude excessive fall rate (treatment - pretreatment falls) was compared between treatment groups. Change in musculoskeletal function (summed score of knee flexor and extensor strength, grip strength, and the timed up&go test) was measured as a secondary outcome. Among subjects in the Cal+D-group, there were significant increases in median serum 25-hydroxyvitamin D (+71%) and 1,25-dihydroxyvitamin D (+8%). Before treatment, mean observed number of falls per person per week was 0.059 in the Cal+D-group and 0.056 in the Cal-group. In the 12-week treatment period, mean number of falls per person per week was 0.034 in the Cal+D-group and 0.076 in the Cal-group. After adjustment, Cal+D-treatment accounted for a 49% reduction of falls (95% CI, 14-71%; p < 0.01) based on the fall categories stated above. Among fallers of the treatment period, the crude average number of excessive falls was significantly higher in the Cal-group (p = 0.045). Musculoskeletal function improved significantly in the Cal+D-group (p = 0.0094). A single intervention with vitamin D plus calcium over a 3-month period reduced the risk of falling by 49% compared with calcium alone. Over this short-term intervention, recurrent fallers seem to benefit most by the treatment. The impact of vitamin D on falls might be explained by the observed improvement in musculoskeletal function.
