[Exercise-based cardiac rehabilitation is associated with reduced risk of myocardial infarction]. / Fysisk träning minskar risk för återinsjuknande i hjärtinfarkt.

In patients with coronary artery disease, exercise-based cardiac rehabilitation (EBCR) is recommended to decrease all-cause and cardiovascular mortality, hospitalisation and risk of myocardial infarction and to improve aerobic capacity and muscle strength and endurance. Before starting the EBCR program, a pre-exercise screening is conducted. Exercise is individually prescribed based on tests of aerobic and muscular strength/endurance, as part of a comprehensive and medically supervised program. A post-exercise assessment is performed to evaluate the effects of exercise and to provide an exercise prescription to encourage life-long exercise.

Access to, use, knowledge, and preferences for information technology and technical equipment among people with chronic obstructive pulmonary disease (COPD) in Sweden. A cross-sectional survey study.

BACKGROUND: The use of information technology can make pulmonary rehabilitation interventions in people with chronic obstructive pulmonary disease (COPD) more flexible and thereby has the potential to reach a larger proportion of the population. However, the success of using information technology in pulmonary rehabilitation is dependent on the end-user's competence in information technology and access to the Internet. The aim was to describe the access to, and the use, knowledge, and preferences of information technology and technical equipment among people with COPD. METHODS: Telephone interviews were conducted using a standardised questionnaire on information technology and technical devises addressing the household, access to and usage of the Internet, contact with authorities, e-commerce, security, the workplace, digital competence, and disabilities. Questions were also posed regarding participants' views on a future eHealth tool for COPD, appropriate content, and the potential likelihood for them to use an eHealth tool for exercise training. RESULTS: In total 137 persons agreed to participate, 17 dropped out resulting in 120 included participants (response rate 88%). The participants (86 women) were aged 51 to 92 years (mean: 72.5), and all severity grades of COPD according to GOLD A-D were represented. Over 90% had access to the Internet. Smartphones were used by 81%, and over 90% used apps. Participants had high knowledge of how to use the Internet, 91% had used the Internet during the last 3 months, 85% almost every day. The most common requests for a future eHealth tool for COPD were evidence-based and trustworthy information on COPD, (including medication, exercise training, inhalation and breathing techniques), communication (chat) with others and with health carers. Access to individually adjusted exercise training, and support, (motivation via prompts, chat rooms, digital information board) was also desired. CONCLUSIONS: The present study showed that people with COPD in Sweden have high access and ability to use the Internet and information technology. They are frequent users and most of them take part in the digital society, even to a higher extent than the general population. The results show that the use of an eHealth tool could be a suitable strategy for people with COPD.

Mobilization Started Within 2 Hours After Abdominal Surgery Improves Peripheral and Arterial Oxygenation: A Single-Center Randomized Controlled Trial.

OBJECTIVE: The aim of this study was to investigate if mobilization out of bed, within 2 hours after abdominal surgery, improved participants' respiratory function and whether breathing exercises had an additional positive effect. METHODS: Participants were 214 consecutively recruited patients who underwent elective open or robot-assisted laparoscopic gynecological, urological, or endocrinological abdominal surgery with an anesthetic duration of >2 hours. They were recruited to a randomized controlled trial. Immediately after surgery, patients were randomly assigned to 1 of 3 groups: mobilization (to sit in a chair) and standardized breathing exercises (n = 73), mobilization (to sit in a chair) only (n = 76), or control (n = 65). The interventions started within 2 hours after arrival at the postoperative recovery unit and continued for a maximum of 6 hours. The primary outcomes were differences in peripheral oxygen saturation (SpO2, as a percentage) and arterial oxygen pressure (PaO2, measured in kilopascals) between the groups. Secondary outcomes were arterial carbon dioxide pressure, spirometry, respiratory insufficiency, pneumonia, and length of stay. RESULTS: Based on intention-to-treat analysis (n = 214), patients who received mobilization and breathing exercises had significantly improved SpO2 (mean difference [MD] = 2.5%; 95% CI = 0.4 to 4.6) and PaO2 (MD = 1.40 kPa; 95% CI = 0.64 to 2.17) compared with the controls. For mobilization only, there was an increase in PaO2 (MD = 0.97 kPa; 95% CI = 0.20 to 1.74) compared with the controls. In the per-protocol analysis (n = 201), there were significant improvements in SpO2 and PaO2 for both groups receiving mobilization compared with the controls. Secondary outcome measures did not differ between groups. CONCLUSION: Mobilization out of bed, with or without breathing exercises, within 2 hours after elective abdominal surgery improved SpO2 and PaO2. IMPACT: The respiratory effect of mobilization (out of bed) immediately after surgery has not been thoroughly evaluated in the literature. This study shows that mobilization out of bed following elective abdominal surgery can improve SpO2 and PaO2. LAY SUMMARY: Mobilization within 2 hours after elective abdominal surgery, with or without breathing exercises, can improve patients' respiratory function.

StayBalanced: implementation of evidence-based fall prevention balance training for older adults-cluster randomized controlled and hybrid type 3 trial.

BACKGROUND: The StayBalanced programme has shown positive effects on fall prevention, balance control and fear of falling. Despite convincing evidence on the efficacy and effectiveness of balance training, there is a gap between research findings and what is provided in community-based and clinical health care settings. Therefore, transferring evidence-based balance training into clinical practice is needed. METHODS: This project, designed as a hybrid type 3 trial, is a cluster-randomized study with a mixed-method design, carried out in primary health care settings. The aim is to investigate the effectiveness of two different strategies to facilitate the implementation of an intervention, the StayBalanced balance training programme, in primary health care, including evaluation of relative changes and maintenance in patient outcomes between intervention arms over 24 months. The StayBalanced programme will be launched through a website with information on the balance training and how to use it in clinical practice. One implementation strategy will include close facilitation, i.e. support and close follow-ups initiated by the researchers, in addition to access to the website. The other strategy simply includes access to the StayBalanced website. Outcome measures in the project consist of implementation outcomes, such as acceptability, feasibility, fidelity and sustainability of the StayBalanced programme. Outcomes at an individual level for older adults participating in the training will include fall-related concerns, health-related quality of life, balance performance, gait, physical activity, muscle strength in lower extremities, number of falls and compliance with training. DISCUSSION: This study will generate new understanding of effective strategies for transferring research to clinical practice and thereby reduce an important knowledge gap, as well as aid decision-making for future implementation of evidence-based methods. Furthermore, it will contribute to improved balance and gait, increased level of physical activity and function, and improved health-related quality of life for the individuals participating in the programme.

Being limited by Parkinson's disease and struggling to keep up exercising; is the group the glue?

Background: People with Parkinson's disease find that exercise helps to improve their physical performance. However, when performed in a group, they also tend to appreciate each other's company.Purpose: After people with Parkinson's disease participated in a community-based group balance exercise program, our aims were to explore the participants' general attitude to their balance ability and exercise, and specifically their experiences of participating in a group exercise.Materials and Methods: Informants were people living with Parkinson's disease at an early stage (n = 15) who had participated in a community-based "Somatosensory Focused Balance Training without Cues." Each informant took part in one face-to-face interview. The interviews were transcribed, according to content analysis, coded independently by two researchers and triangulated together with a third experienced researcher. Categories and themes were derived in consensus.Results: The participants felt limited by their body. They agreed that the group balance exercise program did help with their balance control. Moreover, the vast majority found that the group context implied a positive social contribution to their lives and to their ability to cope with living with the disease.Conclusion: Group balance exercise might constitute a context with potential to improve quality of life for people with Parkinson's disease, not only by improving balance control, but also contributing to social connections, fellowship and the exchange of mutual experiences.Implications for rehabilitationGroup-based exercise in early Parkinson seems to add more than just the physical effects of training, since it also gives a platform for meeting social and emotional needs, as well as addressing physical ability.The group dynamics and the support of peers seem to promote a positive attitude to life and enable people to learn coping strategies from each other.Community-based exercise groups for people with early Parkinson seem to be a way to get out in society and regain a feeling of being part of society.Due to body limits, people with Parkinson's disease must struggle daily, already at an early stage of their disease; this stresses the need to begin rehabilitation early.

"Stay balanced" - effectiveness of evidence-based balance training for older adults transferred into a physical therapy primary care setting - a pilot study.

Purpose: To evaluate the effects of the Stay Balanced program when this is transferred into a clinical setting regarding balance, gait speed, leg muscle strength, concerns about falling, and physical activity.Method: Implementation pilot study with a pre-post intervention design. Fifteen older adults, 75-91 years of age, participated in a progressive balance training program with a focus on divided attention. The balance training was performed in group sessions twice a week for 10 weeks at a primary care physical therapy clinic. Training efficacy was evaluated after completion of training as well as after 3 months using the Mini-Balance Evaluation Systems Test (Mini-BESTest), 10-meter walk test, 30-s chair stand test, Fall Efficacy Scale-International (FES-I), and steps/day.Results: Significant improvements were shown at the 10-week follow up for balance, gait speed, leg muscle strength, and concerns about falling (p < 0.008). At the 3-month follow-up balance, leg muscle strength and concerns about falling showed persistent improvement compared to baseline (p < 0.045). No significant differences were found for physical activity.Conclusions: This study confirms the results of our previous randomized controlled trials (RCTs), and suggests that the Stay Balanced program can be transferred to clinical physiotherapy practice. The program was appreciated by the participants and proved to be safe, effective, and feasible in primary care.Implication for rehabilitationThe Stay Balance program can easily be transferred to clinical practice without losing the effectiveness of the intervention in older adults with balance problems.The program was appreciated by the participants and proved to be safe, effective, and feasible when executed in primary care.Stay Balance program is an individually adjusted and progressive group balance training including exercises with divided attention that can easily be transferred to tasks in daily life.

Long-Term Effects of Balance Training on Habitual Physical Activity in Older Adults with Parkinson's Disease.

The HiBalance program is a progressive and highly challenging balance training intervention incorporating Parkinson's disease (PD) specific balance components. The program improves balance and gait and increases the amount of ambulation in short-term, in older adults with PD. Yet, potential short- and long-term effects on habitual physical activity and sedentary behavior are currently unidentified. The aim of this study was to conduct preplanned secondary analyses of short- and long-term effects of the HiBalance program on objectively measured amount and bouts of brisk walking, sedentary behavior, and total physical activity in older adults with PD. Further, our aim was to investigate demographic, intervention-related, disease-related, and function-related factors potentially related to a difference in activity after intervention. A total of 100 older adults with mild-moderate PD were recruited. The intervention group participated in the HiBalance program, and the control received care as usual and was offered the HiBalance program after study termination. Physical activity data were collected using accelerometers at baseline, after intervention and after 6 and 12 months. A multilevel model was utilized to investigate the postintervention and long-term (6 and 12 months) effects on total physical activity, amount and bouts of brisk walking (i.e., moderate intensity physical activity), and sedentary behavior. Between-group difference for the main outcome brisk walking was at postintervention: Δ -10, CI -23.78 to 3.69 min/day (p < 0.05); 6 months: Δ -10, CI -23.89 to 3.89 min/day (p < 0.05); and 12 months: Δ -4, CI -16.81 to 8.81 min/day (p=0.43). Being part of the intervention group as well as finishing training during spring/summer showed an independent association to increased brisk walking after the intervention period. In conclusion, the HiBalance program increases the physical activity on moderate intensity after intervention and at 6 months but not at 12 months, independently of improved balance. Season seems to influence the effect on the physical activity.

Psychometric properties of the Swedish version of the Falls Efficacy Scale-International for older adults with osteoporosis, self-reported balance deficits and fear of falling.

PURPOSE: Investigate the psychometric properties of the Swedish version of the Falls Efficacy Scale-International (FES-I). METHOD: Cross-sectional study. Community-dwelling older adults with self-reported balance deficits and fear of falling were recruited from an ongoing randomised controlled study to evaluate the psychometric properties of the FES-I using Rasch model analysis. RESULTS: The Rasch model analysis revealed good category function, the questionnaire measured one dimension with an explained variance of 68.6% and item goodness-of-fit with mean square values (MnSq) 0.7-1.44. The item map showed that all items are spread over the scale, which indicates different difficulties in the items. Non-satisfactory person goodness-of-fit was shown with seven persons and showed person misfit according to both the MnSq-value and the z-value, 38 persons (40%) showed a person misfit when only following the threshold for MnSq. CONCLUSIONS: The Swedish version of FES-I shows good psychometric properties with unidimensionality and item goodness-of-fit. Lower person goodness-of-fit was shown probably because of confounding factors that may influence the answers. The transformed values of the FES-I make it possible to use parametric statistics preferable for this population in future research. Implications for rehabilitation The Falls Efficacy Scale-International (FES-I) shows good psychometric properties with unidimensionality, item goodness-of-fit and good item reliability, which means that FES-I is a valuable tool when measuring concerns about falling in an older population with osteoporosis and could be useful in clinical settings. Confounding factors such as pain, high number of falls, low fall self-efficacy, experience of previous falls, and vertigo may influence the answers and result in low person goodness-of-fit.

Assessing postural balance in early Parkinson's Disease-validity of the BDL balance scale.

BACKGROUND: There is a need for a valid assessment test of balance in early Parkinson's disease (PD). OBJECTIVE: To validate the Bäckstrand Dahlberg Liljenäs Balance Scale (BDL), a test of balance performance constructed to assess mild to moderate balance disability due to neurological disease, for use in persons with early PD. METHODS: Cross-sectional psychometric evaluation study from a convenience sample community-dwelling persons with PD (n = 28). MAIN MEASURES: The BDL was validated using the Berg Balance Scale (BBS), the motor part of the Unified Parkinson's Disease Rating Scale (mUPDRS), the Timed Up and Go (TUG) and Timed Up and Go-cognition (CTUG). Correlations were calculated by Spearman's rank correlation coefficient (rho). Rasch analyses were used to test the internal construct of the BDL. The result from the BDL was compared to a healthy reference group. RESULTS: The correlation between the BDL and the BBS (rho = 0.703) was high positive, while for mUPDRS (rho = -0.280), TUG (rho = -0.321) and CTUG (rho = -0.361) the correlations with the BDL were negligible to low negative. The Rasch analyses for the BDL showed a good distribution of the task difficulties with neither ceiling nor floor effect among individual measures. There was a significant difference (p = 0.03) in performance of the BDL between the PD group and the healthy reference group. CONCLUSIONS: The BDL Balance Scale can be considered a valid clinical assessment test when evaluating balance training interventions in persons with early PD. It can be recommended as an outcome measure in clinical practice and in clinical research within this population.

Falls and fear of falling predict future falls and related injuries in ambulatory individuals with spinal cord injury: a longitudinal observational study.

QUESTIONS: What is the 1-year incidence of falls and injurious falls in a representative cohort of community-dwelling ambulatory individuals with chronic spinal cord injury? What are the predictors of recurrent falls (more than two/year) and injurious falls in this population? DESIGN: One-year longitudinal observational multi-centre study. PARTICIPANTS: A representative sample of 68 (of 73 included) community-dwelling ambulatory individuals with traumatic SCI attending regular follow-up programs at rehabilitation centres. OUTCOME MEASURES: Primary outcome measures were incidence and predictors of recurrent falls (more than two/year) and injurious falls reported every 2 weeks for 1year. RESULTS: A total of 48% of participants reported recurrent falls. Of the 272 reported falls, 41% were injurious. Serious injuries were experienced by 4% of participants, all of whom were women. Multivariate logistic regression analysis showed that recurrent falls in the previous year (OR=111, 95% CI=8.6 to 1425), fear of falling (OR=6.1, 95% CI=1.43 to 26) and longer time taken to walk 10m (OR=1.3, 95% CI=1.0 to 1.7) were predictors of recurrent falls. Fear of falling (OR=4.3, 95% CI=1.3 to 14) and recurrent falls in the previous year (OR=4.2, 95% CI=1.2 to 14) were predictors of injurious falls. CONCLUSION: Ambulatory individuals have a high risk of falling and of fall-related injuries. Fall history, fear of falling and walking speed could predict recurrent falls and injurious falls. Further studies with larger samples are needed to validate these findings. [Jørgensen V, Butler Forslund E, Opheim A, Franzén E, Wahman K, Hultling C, Seiger Å, Ståhle A, Stanghelle JK, Roaldsen KS (2017) Falls and fear of falling predict future falls and related injuries in ambulatory individuals with spinal cord injury: a longitudinal observational study.

High incidence of falls and fall-related injuries in wheelchair users with spinal cord injury: A prospective study of risk indicators.

OBJECTIVE: To identify risk indicators for, and incidence of, recurrent falls and fall-related injuries in wheelchair users with traumatic spinal cord injury. DESIGN: Prospective multi-centre study. SUBJECTS: One hundred and forty-nine wheelchair users with spinal cord injury attending follow-up in Sweden and Norway. METHODS: Inclusion criteria: wheelchair users ≥ 18 years old with traumatic spinal cord injury ≥ 1 year post-injury. EXCLUSION CRITERIA: individuals with motor complete injuries above C5. Falls were prospectively reported by text message every second week for one year and were followed-up by telephone interviews. Outcomes were: fall incidence, risk indicators for recurrent (> 2) falls and fall-related injuries. Independent variables were: demographic data, quality of life, risk willingness, functional independence, and exercise habits. RESULTS: Of the total sample (n = 149), 96 (64%) participants fell, 45 (32%) fell recurrently, 50 (34%) were injured, and 7 (5%) severely injured. Multivariate logistic regression analysis showed that reporting recurrent falls the previous year increased the odds ratio (OR) of recurrent falls (OR 10.2, p < 0.001). Higher quality of life reduced the OR of fall-related injuries (OR 0.86, p = 0.037). CONCLUSION: Previous recurrent falls was a strong predictor of future falls. The incidence of falls, recurrent falls and fall-related injuries was high. Hence, prevention of falls and fall-related injuries is important.

Short- and Long-Term Effects of Balance Training on Physical Activity in Older Adults With Osteoporosis: A Randomized Controlled Trial.

BACKGROUND AND PURPOSE: We have developed a 12-week balance training program for older adults shown to improve fall-related concerns, gait speed, balance performance, and physical function. We hypothesized that this balance training would also contribute to higher habitual physical activity (PA) levels and improved health-related quality of life (HRQoL). The primary aim was to evaluate short- and long-term effects of the balance training program on objectively measured habitual PA in older adults with osteoporosis. Secondary aims were to assess the effects of the balance training on HRQoL, and to study whether any effects on PA were associated with changes in HRQoL, gait speed, balance performance, fall-related concerns, and physical function. METHODS: A randomized controlled trial with follow-up at 3, 9, and 15 months, including 91 participants with osteoporosis (75.6 ± 5.4 years), compared a balance training group (n = 61) with a control group (n = 30). The primary outcome was effect on habitual PA measured as steps/day, dichotomized into less than 5000 or 5000 or more steps/day. Physical activity was assessed with pedometers (Yamax) and accelerometers (Actigraph), HRQoL with the Short Form-36 (SF-36), gait with a GAITRite walkway, balance performance with Modified-Figure-Eight test and one-leg stance, fall-related concerns with Falls Efficacy Scale International, and physical function with the advanced lower extremity subscale of the questionnaire Late Life Function and Disability Instrument. Statistical methods used were multivariate logistic regression and logistic generalized estimating equation. RESULTS: Sixty-eight participants completed the short-term follow-up at 3 months, and 53 participants completed the long-term follow-up at 15 months. Per-protocol analysis (n = 68) showed that the odds ratio for having a daily step count of 5000 or more at 3 months was 6.17 (95% confidence interval, 1.23-30.91), P = .027, for the intervention group compared with the control group. The longitudinal analysis (n = 91) showed that the odds ratio for having a daily step count of 5000 or more at 15 months was 2.02 (95% confidence interval, 0.88-4.64), P = .096, for the intervention group compared with the control group. The mental component sum of the SF-36 improved significantly from baseline to 3 months in the intervention group, and the physical component sum improved in both groups, but no statistically significant differences were found between groups. No associations were found between PA and changes in covariates. DISCUSSION AND CONCLUSIONS: The short-term evaluation showed that balance training increased habitual PA in community-dwelling older adults with osteoporosis. A significantly higher proportion of participants in the intervention group reached a level of 5000 or more steps/day, which is important for overall health. This effect was not associated with improvements in HRQoL, gait speed, balance performance, or fall-related concerns, and did not persist through the long-term follow-up. To accomplish a sustained PA change, a prolonged intervention or more support regarding habitual PA may be required, such as reinforcement with personalized behavior change counseling or PA on prescription.

Objectively Assessed Physical Activity and its Association with Balance, Physical Function and Dyskinesia in Parkinson's Disease.

BACKGROUND: The desirable effects of physical activity in individuals with Parkinson's disease are well-known, although according to results from previous studies factors associated with objectively assessed physical activity are not fully investigated. OBJECTIVE: To investigate demographic, disease-related and mobility-related factors that associate with objectively measured physical activity, in a sample of older adults with mild to moderate Parkinson's disease. METHODS: Demographic, disease-related and mobility-related factors were gathered by interview from a total of 91 older adults with Parkinson's disease, followed by an evaluation of balance control using the Mini-BESTest. After initial testing, participants wore a tri-axial accelerometer during a week of free-living. Correlation analysis and multiple linear regression was used to investigate factors associated with total PA, represented by total activity counts, and time in brisk walking. RESULTS: Motor impairment, physical function, body mass index and dyskinesia contributed to the variance of total physical activity, explaining 34 % of the variance, while physical function and balance control were significant factors associated with brisk walking, explaining 22 %. CONCLUSIONS: This study identified factors that have not been shown to associate with objectively measured physical activity previously, such as dyskinesia, balance control and self-rated physical function. The findings also demonstrated that associated factors differ, depending on the activity behavior being investigated. However, other factors than those included in this study may also be of importance.

Factors Associated With Recurrent Falls in Individuals With Traumatic Spinal Cord Injury: A Multicenter Study.

OBJECTIVE: To identify factors associated with recurrent falls in individuals with traumatic spinal cord injury (SCI). DESIGN: Cross-sectional multicenter study. SETTING: Two specialized rehabilitation centers. PARTICIPANTS: Included: individuals with traumatic SCI ≥1 year postinjury who were aged ≥18 years. Excluded: individuals with motor complete injuries above C5 or below L5. The study sample comprised participants (N=224; 151 wheelchair users, 73 ambulatory; 77% men; mean age ± SD, 50±15y; median time since injury, 15y [range, 1-56y]) who were consecutively recruited at regular follow-up. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Primary outcome was factors associated with recurrent falls (defined as low frequent [0-2] or recurrent [>2]) the previous year. Independent variables were demographic data, wheelchair user or ambulatory, work, health-related quality of life, risk willingness, alcohol consumption, ability to get up from the ground, and exercise habits. RESULTS: Fifty percent reported recurrent falls. In the final multiple logistic regression model, ambulation (odds ratio [OR]=2.67; 95% confidence interval [CI], 1.33-5.37), ability to get up from the ground (OR=2.22; 95% CI, 1.21-4.10), and regular exercise (OR=1.86; 95% CI, 1.05-3.31) were associated with recurrent falls (P≤.05), and with increasing age the OR decreased (OR=.97; 95% CI, .95-.99). CONCLUSIONS: Individuals with SCI should be considered at risk of recurrent falls, and thereby at risk of fall-related injuries. Fall prevention programs should be focused on ambulatory, younger, and more active individuals who had the highest risks for recurrent falls.

Long-term effects of a progressive and specific balance-training programme with multi-task exercises for older adults with osteoporosis: a randomized controlled study.

OBJECTIVE: To evaluate long-term effects of balance-training on concerns about falling, gait, balance performance, and physical function in older adults with osteoporosis and increased risk of falling. DESIGN: Randomized controlled trial, including three groups (training, training+physical activity, and control group), with follow-ups at three, nine, and 15 months. Short-term, three-month follow-up, benefits for those who fulfilled the first follow-up ( n = 69) have previously been reported. SETTING: Stockholm, Sweden. PARTICIPANTS: A total of 96 elderly, age 66-87, with verified osteoporosis. INTERVENTIONS: Balance-training programme including dual- and multitasks, with or without supplementary physical activity, three times/week over 12 weeks. MEASUREMENTS: Concerns about falling Falls Efficacy Scale -International (FES-I), walking at preferred speed with and without a cognitive dual-task and at fast speed, balance tests (one-leg stance and modified figure-of-eight), and physical function Late-Life Function and Disability Instrument (LLFDI). RESULTS: Participants in the training group maintained positive effects throughout the study period for concerns about falling (baseline vs. 15 months, median 27.5 vs. 23 points, p < 0.001) and walking performance (baseline vs. 15 months, p ⩽ 0.05 with an improvement of 0.9-1.4 m/s). The Training+physical activity group declined to baseline values at the nine-month follow-up, and were even lower at the 15-month follow-up for concerns about falling (median 26 vs. 26 points), walking performance (changes of -0.02 to 0.04 m/s), and physical function (mean 44.0 vs. 42.9 points). The control group remained unchanged throughout the study period. CONCLUSIONS: This balance-training programme reduced concerns about falling, and also improved gait in older adults with osteoporosis and increased risk of falling in a long-term perspective - important issues for fall prevention.

Gait Speed, Quality of Life, and Sedentary Time are Associated with Steps per Day in Community-Dwelling Older Adults with Osteoporosis.

AIM: To describe objectively-measured physical activity levels and patterns among community-dwelling older adults with osteoporosis, impaired balance, and fear of falling, and to explore the associations with gait, balance performance, falls self-efficacy, and health-related quality of life (HRQoL). METHODS: Ninety-four individuals (75.6 ± 5.4 years) were included. Physical activity was assessed with pedometers and accelerometers. Mean steps/day, dichotomized into < 5,000 or ≥ 5,000 steps/day, and time spent in different physical activity intensities were analyzed. Gait was assessed with a GAITRite walkway, balance performance was assessed with the modified figure-eight test and one-leg stance, falls self-efficacy was assessed with the Falls Efficacy Scale International, and HRQoL was assessed with Short Form-36. RESULTS: Mean steps/day were 6,201 (991-17,156) and 40% reported < 5,000 steps/day. Participants with < 5,000 steps/day spent more time sedentary, had slower gait speed, poorer balance performance, and lower HRQoL than participants with ≥ 5,000 steps/day. No participants with < 5,000 met the recommended level of physical activity.

"Better safe than sorry": a qualitative content analysis of participant's perspectives of fall-related concerns and balance in older women with osteoporosis after balance training.

PURPOSE: To explore how older women with osteoporosis perceive fall-related concerns and balance in daily life after having participated in balance training. METHODS: Explorative study. Semi-structured interviews were conducted with 19 women (66-84 years), with osteoporosis recruited from an ongoing RCT; participants were asked about their perceived fall-related concerns and balance. Interviews were taped and transcribed verbatim. Data were analyzed using inductive qualitative content analysis. RESULTS: One underlying theme emerged: "Internalized risk perception related to experience of bodily fragility", and three manifest categories: empowerment, safety and menace. A dynamic process between the categories was found, in which contextual and personal factors influenced perceptions of fall-related concerns and balance, i.e. winter season may lead a person who is highly empowered and/or uses active strategies into a situation of perception of menace and avoidance of activity. CONCLUSION: To cope with the fragility caused by osteoporosis informants had an internalized risk perception that protected them against possible threats and harm. Informants perceived improved empowerment and self-efficacy after participation in balance training. They resumed activities and became more active and independent in daily life using safety precautions and fall-prevention strategies. Depending on contextual factors, some situations still invoked fear and led to avoidance. Implication for Rehabilitation Risk awareness protecting against possible threats and harms seems to be internalized in older women living with osteoporosis. When designing fall prevention programs, it is important to recognize that contextual and personal factors have a major influence on how older women with osteoporosis perceive fall-related concerns and balance. Perception of fragility and risk seems to be a significant problem for older women with osteoporosis and health-care providers should encourage their patients to participate in tailored balance training programs to overcome these concerns.

"You Have to Keep Moving, Be Active": Perceptions and Experiences of Habitual Physical Activity in Older Women With Osteoporosis.

BACKGROUND: Physical activity (PA) is essential for older adults with osteoporosis, and health care professionals play important roles in promoting PA and encouraging patients to make healthy choices. However, many factors influence habitual PA, and there is only limited knowledge about the perceptions and experiences of PA among older women with osteoporosis. OBJECTIVES: The purpose of this study was to describe perceptions and experiences of PA and the factors that influence habitual PA among older adults with osteoporosis, impaired balance, and fear of falling. DESIGN: This was a qualitative interview study applying interpretive content analysis with an inductive approach. METHODS: Informants were a purposeful sample of 18 women, aged 66 to 86 years, with osteoporosis, impaired balance, and fear of falling. Individual, semistructured, face-to-face interviews were recorded, transcribed, condensed, and coded to find subthemes and themes. RESULTS: The overall theme found was "Physical activity--a tool for staying healthy with osteoporosis." This overall theme comprised 2 main themes interpreting the challenges and possibilities of being physically active with osteoporosis. These themes were not separate but rather linked to each other like 2 sides of the same coin, with factors that could act as both barriers to and facilitators of PA. Personal preferences and osteoporosis-related concerns influenced habitual PA, and individualization was perceived as important. LIMITATIONS: Some results may be context specific and limit the transferability to people with other cultural or socioeconomic backgrounds. CONCLUSIONS: The women perceived that PA was an important tool to maintain health with osteoporosis and believed that they had a responsibility to use this tool. They had adapted to disease-specific limitations and developed strategies to overcome challenges and barriers to PA. Lack of PA promotion and conflicting advice about PA from physicians created uncertainty. Encouragement and guidance from physical therapists, individually or in groups, were very important.

Accelerometer Cut Points for Physical Activity Assessment of Older Adults with Parkinson's Disease.

OBJECTIVE: To define accelerometer cut points for different walking speeds in older adults with mild to moderate Parkinson's disease. METHOD: A volunteer sample of 30 older adults (mean age 73; SD 5.4 years) with mild to moderate Parkinson's disease walked at self-defined brisk, normal, and slow speeds for three minutes in a circular indoor hallway, each wearing an accelerometer around the waist. Walking speed was calculated and used as a reference measure. Through ROC analysis, accelerometer cut points for different levels of walking speed in counts per 15 seconds were generated, and a leave-one-out cross-validation was performed followed by a quadratic weighted Cohen's Kappa, to test the level of agreement between true and cut point-predicted walking speeds. RESULTS: Optimal cut points for walking speeds ≤ 1.0 m/s were ≤ 328 and ≤ 470 counts/15 sec; for speeds > 1.3 m/s, they were ≥ 730 and ≥ 851 counts/15 sec for the vertical axis and vector magnitude, respectively. Sensitivity and specificity were 61%-100% for the developed cut points. The quadratic weighted Kappa showed substantial agreement: κ = 0.79 (95% CI 0.70-0.89) and κ = 0.69 (95% CI 0.56-0.82) for the vertical axis and the vector magnitude, respectively. CONCLUSIONS: This study provides accelerometer cut points based on walking speed for physical-activity measurement in older adults with Parkinson's disease for evaluation of interventions and for investigating links between physical activity and health.

The Effects of Highly Challenging Balance Training in Elderly With Parkinson's Disease: A Randomized Controlled Trial.

BACKGROUND: Highly challenging exercises have been suggested to induce neuroplasticity in individuals with Parkinson's disease (PD); however, its effect on clinical outcomes remains largely unknown. OBJECTIVE: To evaluate the short-term effects of the HiBalance program, a highly challenging balance-training regimen that incorporates both dual-tasking and PD-specific balance components, compared with usual care in elderly with mild to moderate PD. METHODS: Participants with PD (n = 100) were randomized, either to the 10-week HiBalance program (n = 51) or to the control group (n = 49). Participants were evaluated before and after the intervention. The main outcomes were balance performance (Mini-BESTest), gait velocity (during normal and dual-task gait), and concerns about falling (Falls Efficacy Scale-International). Performance of a cognitive task while walking, physical activity level (average steps per day), and activities of daily living were secondary outcomes. RESULTS: A total of 91 participants completed the study. After the intervention, the between group comparison showed significantly improved balance and gait performance in the training group. Moreover, although no significant between group difference was observed regarding gait performance during dual-tasking; the participants in the training group improved their performance of the cognitive task while walking, as compared with the control group. Regarding physical activity levels and activities of daily living, in comparison to the control group, favorable results were found for the training group. No group differences were found for concerns about falling. CONCLUSIONS: The HiBalance program significantly benefited balance and gait abilities when compared with usual care and showed promising transfer effects to everyday living. Long-term follow-up assessments will further explore these effects.
