- To investigate the long-term effects of habitual physical activity on changes in musculoskeletal health, functional performance, and fracture risk in elderly men and women. Ten-year prospective population-based study. Malmo-Sjobo Prospective Study, Sweden. Participants were 152 men and 206 women aged 50, 60, 70, and 80 who were followed for 10 years. Distal radius bone mineral density (BMD) (single photon absorptiometry), upper limb muscle (grip) strength, balance, gait velocity, occupational and leisure-time activity, and fractures (interview-administered questionnaire) were reassessed after 10 years. Annual changes for all measures were compared between participants with varying habitual physical activity histories at baseline and follow-up: inactive-inactive (n=202), active-inactive (n=47), inactive-active (n=49), and active-active (n=60). Data for men and women were pooled, because there were no sex-by-activity group interactions. To detect possible differences in fracture incidence between the varying habitual activity groups, participants were classified into two activity groups based on their activity classification at baseline and follow-up: inactive:less active versus active:more active. The annual rate of bone loss was 0.6% per year less in individuals classified as active at both time points than in those classified as inactive at both time points (P <.01). Similar results were observed for balance, but there was no effect of varying habitual activity on changes in muscle strength or gait velocity. There were also no differences in fracture incidence between individuals categorized as active:more active and those categorized as inactive:less active during the follow-up (adjusted hazard ratio=0.90, 95% confidence interval (CI)=0.42-1.90). This study showed that elderly men and women who maintained a habitually active lifestyle over 10 years had lower bone loss and retained better balance than those who remained habitually inactive.

- OBJECTIVE: The aims of this study were: to follow the course of recovery of motor function following acute stroke, as assessed by the Physiotherapy Clinical Outcome Variables Scale (COVS), and; to investigate the ability of this instrument to predict length of hospital stay, discharge destination and future home facility. METHODS: In this prospective longitudinal study, COVS was registered at admission and discharge from an acute stroke unit and at 3 months post-stroke onset. SUBJECTS: Sixty subjects were recruited consecutively from a sample of patients after first-ever acute stroke, and of these, 50 received follow-up assessment. OUTCOME VARIABLES: Length of hospital stay, discharge destination and home facility 3 months post-stroke. RESULTS: The overall COVS scores increased significantly during the 3-month follow-up. The admission COVS score correlated negatively with length of stay. A cut-off at 50 points and 41 points could predict discharge destination and future home facility, respectively. CONCLUSION: COVS measures improvements and can predict length of hospital stay, discharge destination and future home facility. Thus, it could be used in early prediction for effective planning of the acute stroke unit services and efficient discharge planning.

- Information on objectively assessed physical activity in elderly people is scarce. The aim of this study was to investigate accelerometer measures in elderly women, and its relation to other indices of physical activity and bone density. A subset of 57 women, all 80 years old, (range 80.0-80.7) of the Malmo OPRA study was equipped with an MTI accelerometer for a period of 5-7 days. A 7-day activity log was used. At baseline a self-assessment questionnaire was used and isometric muscle strength (knee), gait speed, balance and bone density measurements [dual-energy X-ray absorptiometry (total body, hip, and spine), and quantitative ultrasound of the calcaneus] were measured. About 14% (8 out of 57) had a moderate to vigorous physical activity (MVPA) (>1,952 counts per min [CPM]) exceeding 30 min/day. The median CPM was 18. When compared to questionnaire data, the correlation between MVPA and physical activity was 0.50 (P < 0.001). The corresponding result for CPM was 0.48, P < 0.001. When compared to the activity log, the correlation between MVPA and physical activity away from home was 0.49 (P < 0.001). The corresponding result for CPM was 0.55, P < 0.001. The correlation between MVPA and gait speed was 0.41 (P = 0.002). The corresponding result for CPM was 0.40, P = 0.002. There were no correlations to the measurements of muscle strength, balance or bone density (all P >/= 0.07). Accelerometers can be used for measuring of physical activity also of the elderly. Questions on daily physical activity correlated modestly with accelerometer results in elderly women. Accelerometer results were not correlated to measures of balance, muscle strength and bone density.

- Vitamin D supplements have been used to prevent fractures. The effect may be mediated through increased bone mass, but also through reduced falling propensity. The aim of this study was to evaluate the association between 25-hydroxy vitamin D levels (25OHD), fall-associated variables (including tests of functional performance), and fracture in ambulatory women. At baseline 25OHD was measured in 986 women. Fall-associated variables were investigated at baseline. Fractures were recorded during a 3-year follow-up. Four percent of the women had 25OHD levels below 20 ng/ml (50 nmol/l), and 26% had 25OHD levels below 30 ng/ml (75 nmol/l). 25OHD correlated with gait speed (r =0.17, P <0.001), the Romberg balance test (r =0.14, P <0.001), self-estimated activity level (r =0.15, P <0.001), and thigh muscle strength (r =0.08, P =0.02). During the 3-year follow-up, 119 out of the 986 women sustained at least one fracture. The Cox proportional hazard ratio (HR) (95% confidence interval) for sustaining a fracture during the follow-up was 2.04 (1.04-4.04) for the group of women with 25OHD below 20 ng/ml, in which 9 out of 43 women sustained a fracture. Thirty-two of the 256 women with 25OHD levels below 30 ng/ml sustained a fracture during the follow-up, with a non-significant HR of 1.07 (1.07-1.61). This cohort of elderly, ambulatory women had a high mean 25OHD. A low 25OHD was associated with inferior physical activity level, gait speed and balance. A 25OHD level below 30 ng/ml was not associated with an increased risk of fractures in this study. However, a subgroup of women with 25OHD levels below 20 ng/ml had a tendency to an increased risk of fractures, which may be associated with an inferior physical activity and postural stability.

- The objective of this study is to investigate whether vestibular rehabilitation can improve balance, reduce self-perceived handicap because of dizziness and, if possible, reduce falls among dizzy patients in primary healthcare. The study also finds out which of the balance measures and measure of self-perceived handicap, if any, predicted the risk of falls. The design of this study is an intervention study with control group. Fifty-eight patients, 65 years and older, with multisensory dizziness were taken as participants. The intervention group trained vestibular rehabilitation twice a week for 9 weeks. All patients were assessed at baseline and after 3 months, with four different balance measures and the Dizziness Handicap Inventory. After 6, 9 and 12 months, a follow-up by telephone was performed and, at 12 months, the patients also filled out a Dizziness Handicap Inventory questionnaire. Statistically significant differences were found between the groups between baseline and 3 months in one static balance measure and in one dynamic measure (P=0.038 and 0.044). In total, 40 falls were reported, 31 were classified as intrinsic falls, 26 of them caused by vertigo and nine falls were classified as extrinsic. No difference was found between the two groups in proportions of patients who fell. Poor ability to stand in tandem stance doubled the risk for falls. Vestibular rehabilitation can improve balance in elderly patients with multisensory dizziness. Vertigo is a common cause of falls in this group of patients and vestibular rehabilitation is a feasible treatment.

- Aim: This study explored professionals' and trusted community inhabitants' explanations of the violence between intimate partners and their suggestions for preventive activities. It was performed in a rural district in northern Vietnam. Methods: A total of 20 men and 20 women were strategically selected for focus-group discussions and the analyses followed the procedure for qualitative thematic content analysis. Results: It was pointed out that violence against women was not discussed openly in the community and women subjected to violence kept silent and avoided seeking help in order not to reveal what was happening in the family. The informants perceived the violence as an interplay between individual and family-related factors and sociocultural norms and practices where Confucian ideology exerted a strong influence. When it came to prevention, there was a strong belief in educating the people and in enforcing policy and law. Conclusions: As described by the informants, traditional attitudes to gender roles and women's power disadvantage are found to be behind most of the explanations for intimate partner violence. Collaboration between sectors at local level, between the health sector and other bodies, and with community leaders as spokesmen would help to improve openness and reduce society's tolerance of violence against women. The mass media also have an important role to play.
