A 12-month randomized controlled trial of balance training in elderly women with osteoporosis: Improvement of quality of life

Effects of exercise on bone density and physical performance in postmenopausal women: A systematic review and meta-analysis

BACKGROUND

Postmenopausal bone loss and decreased physical performance are commonly presented issues. This study aimed through systematic review and meta-analysis to examine the benefits of adding exercise to medicine/supplements in postmenopausal women.

METHODS

A systematic search was conducted of four electronic databases for articles published from inception to December 2023. Clinical controlled trials comparing the effect of additional exercise and medicine/supplements alone in postmenopausal women were included. The outcomes studied were bone mineral density (BMD) and physical performance. The quality of evidence was evaluated by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE).

RESULTS

Nineteen articles with 1249 participants were included in this study for systematic review and meta-analysis. The results showed that additional exercise was not associated with significantly improved BMD at the lumbar spine and hip joint compared with medicine/supplements only. However, results of subgroup analysis of exercise types showed a significant improvement in lumbar spine BMD by combining multiple types of exercise training (SMD = 0.37; 95% confidence interval [CI] = 0.01-0.72; p = .04). Furthermore, additional exercise significantly improved lower extremity muscle strength (Standard Mean Difference [SMD] = 1.77; 95% CI = 0.56-2.98; p = .004), Berg's Balance Scale (SMD = 0.72; 95% CI = 0.12-1.32; p = .02), Timed Up and Go (SMD = -1.07; 95% CI = -1.35--0.78; p < .001), fear of falling (SMD = 1.32; 95% CI = 0.89-1.75; p < .001), and the quality of life (SMD = 1.39; 95% CI = 0.74-2.05; p < .001). The quality level of the evidence was between low to very low.

CONCLUSIONS

The significant value of the exercise was demonstrated through enhancing physical performance and quality of life. Moreover, combining various exercise training programs has shown a positive effect on BMD at the lumbar spine. Therefore, for postmenopausal women, combining exercise with medicine/supplements is recommended to further improve physical function and specific areas of BMD. (PROSPERO: CRD42023390633).

Effect of 12-Week-Zumba Training on Postural Balance, Lower Limb Strength, Mood and Quality of Life in Postmenopausal Women

We aimed to investigate 12-week-Zumba training effects on physical and psychological parameters, and quality of life (QoL) in postmenopausal women. Forty-two postmenopausal women were randomly allocated to a control group or a Zumba group (ZG). Postural balance, lower limb strength, mood level, and QoL were assessed before and after the 12-week-Zumba training. The ZG showed significantly better balance performances under all conditions such as on firm and foam surfaces with opened and closed eyes as well as improvements in limb strength, mood and QoL compared to their baselines. Thereby, 12-week-Zumba training was effective in improving postural balance, limb strength, mood and, QoL in postmenopausal women.

Position Statement: Exercise Guidelines for Osteoporosis Management and Fall Prevention in Osteoporosis Patients

BACKGROUND

The effectiveness of exercise for improving osteoporosis and fall prevention in patients diagnosed with osteoporosis or osteopenia has not been fully summarized. The Korean Society for Bone and Mineral Research and the Korean Society of Exercise Physiology has developed exercise guidelines for patients with osteoporosis or osteopenia and provide evidence-based recommendations.

METHODS

A systematic review identified randomized controlled trials (RCT) assessing the effect of resistance, impact, balance, aerobic training, and physical activity in osteoporosis and osteopenia on bone quality, physical performance, quality of life, and fall prevention. PubMed, Embase, KoreaMed, and RISS were searched from January 2000 to August 2022. Ten key questions were established to review the evidence and formulate recommendations.

RESULTS

The 50 RCTs reported that even with osteoporosis and osteopenia, resistance and impact training consistently maximized bone strength, improved body strength and balance, and eventually reduced fall incidences. Resistance exercise combining 3 to 10 types of free weight and mechanical exercise of major muscle groups performed with an intensity of 50% to 85% 1-repetition maximum, 5 to 12 repetitions/set, 2 to 3 days/week, for 3 to 12 months is recommended. Impact exercises such as jumping chin-ups with drop landings and jump rope performed 50 jumps/session for at least 6 months with 3 or more days/week are recommended.

CONCLUSIONS

A multi-component exercise mainly comprised of resistance and impact exercise seems to be an effective strategy to attenuate the risk factors of osteoporosis and osteopenia. The integration of exercise guidelines and individualized exercise plans has significant potential to reduce the morbidity and mortality of osteoporosis.

Exploring Older Adults' Experiences of a Home-Based, Technology-Driven Balance Training Exercise Program Designed to Reduce Fall Risk: A Qualitative Research Study Within a Randomized Controlled Trial

BACKGROUND AND PURPOSE

With an aging population, falls have become an increasing public health concern. While face-to-face exercise programs have demonstrated efficacy in reducing falls, their effectiveness is hampered by low participation and adherence. Digital technologies are a novel and potentially effective method for delivering tailored fall prevention exercise programs to older adults. In addition, they may increase the reach, uptake, and sustainability of fall prevention programs. Therefore, understanding older adults' experiences of using technology-driven methods is essential. This study explored the user experience of StandingTall , a home-based fall prevention program delivered through a tablet computer.

METHODS

Fifty participants were recruited using purposive sampling, from a larger randomized controlled trial. Participants were selected to ensure maximum variability with respect to age, gender, experience with technology, and adherence to the program. Participants undertook a one-on-one structured interview. We followed an iterative approach to develop themes.

RESULTS AND DISCUSSION

Eight themes were identified. These fall under 2 categories: user experience and program design. Participants found StandingTall enjoyable, and while its flexible delivery facilitated exercise, some participants found the technology challenging. Some participants expressed frustration with technological literacy, but most demonstrated an ability to overcome these challenges, and learn a new skill. Older adults who engaged in a technology-driven fall prevention program found it enjoyable, with the flexibility provided by the online delivery central to this experience. While the overall experience was positive, participants expressed mixed feelings about key design features. The embedded behavior change strategies were not considered motivating by most participants. Furthermore, some older adults associated the illustrated characters with gender-based stereotypes and negative views of aging, which can impact on motivation and preventive behavior.

CONCLUSION

This study found digital technologies are an effective and enjoyable method for delivering a fall prevention program. This study highlights that older adults are interested in learning how to engage successfully with novel technologies.

Breathing Control Exercises Delivered in a Group Setting for Patients with Chronic Obstructive Pulmonary Disease: A Randomized Controlled Trial

Breathing control exercises are an important component of occupational therapy in patients with chronic obstructive pulmonary disease (COPD). Delivering these exercises in group settings may enhance their benefits. Therefore, this study assessed the effectiveness of breathing control exercises delivered in a group format to patients with severe COPD remitting from an acute pulmonary exacerbation. This randomized controlled trial of 6 weeks’ duration compared the addition of breathing exercise sessions delivered in a group setting to a standard exercise inpatient rehabilitation program (usual care) versus usual care alone. The standard exercise program consisted of endurance and strength training and therapeutic patient education. The intervention group received, in addition to usual care, 20 sessions of 30 min duration of breathing control exercises in a group setting. The primary outcome was quality of life (Saint George’s Respiratory Questionnaire). Secondary outcomes were the COPD assessment test, modified Borg scale, handgrip strength test, and five-time sit-to-stand test. Thirty-seven patients aged 69 ± 7 years were recruited. After the 6-week period, all outcomes significantly improved and exceeded the minimal clinically important difference in the intervention group only. Between-group changes were significant for each outcome. Conclusions: breathing control exercises in a group setting provide clinically relevant benefits in patients with severe COPD who are remitting from an acute pulmonary exacerbation.

Rationale and Feasibility of Resistance Training in hEDS/HSD: A Narrative Review

Hypermobile Ehlers-Danlos Syndrome (hEDS) and hypermobility spectrum disorder (HSD) are genetic conditions characterized by increased joint hypermobility, often in the presence of other signs or symptoms if syndromic. This hypermobility can result in significant pain and ultimately decreased participation in recreational or competitive activity. Rehabilitation of patients with hEDS/HSD is not well understood, particularly since presentation can be relatively heterogenous. Regardless, more research is needed, particularly regarding resistance training, to allow patients with hEDS/HSD to participate in the activities they enjoy. The purpose of this narrative review is to provide an overview of the clinical features displayed by those with hEDS/HSD that have been found to be improved with resistance training in other populations, and to present the current evidence for resistance training in all types of study designs, ranging from case studies to randomized controlled trials.

Effect of class IV laser therapy and Pilates exercises on bone density and pain in primary osteoporosis: a randomised controlled trial

Background/aims

Osteoporosis is a systemic disorder characterised by a decrease in bone quality and density. This causes the bones to become weak and unable to withstand mild stresses, and the associated pain is made worse with activities. The aim of this study was to investigate the effect of class IV laser therapy and Pilates exercises on bone mineral density and pain in patients with primary osteoporosis.

Methods

A total of 60 patients with osteoporosis (40 women and 20 men) participated in this study. Their age ranged between 40 and 60 years. They were allocated randomly to three groups: Group A (n=20) received multiwave locked system laser therapy, group B (n=20) patients received Pilates exercises and group C (n=20) received multiwave locked system laser therapy and Pilates exercises. The treatment programme took place three times a week for 8 weeks. Bone mineral density of the lumbar spine (L1–L4) was measured by dual-energy X-ray absorptiometry and pain intensity during activities was measured by using the Numeric Pain Rating Scale. Evaluation of lumbar bone mineral density and pain intensity were performed before and after 8 weeks.

Results

The statistical analysis of this study revealed there was a significant increase of T-scores post-treatment compared to pre-treatment within group A (P=0.0001; P<0.05), group B (P=0.0001; P<0.05), and group C (P=0.0001), with improvement percentages of 19.59, 34.69 and 50.66% respectively. There was a decrease of pain intensity during activities post-treatment compared to pre-treatment within group A (P=0.0001; P<0.05), group B (P=0.0001; P<0.05) and group C (P=0.0001), with improvement percentages of 41.28, 54.39 and 70.09% respectively.

Conclusions

Class IV laser therapy and Pilates exercises are useful therapeutic modalities to increase bone mineral density and decrease pain in patients with osteoporosis, but combining them is more effective than using them separately.

Can the exercise-based and occupational therapy improve the posture, strength, and mobility in elderly Greek subjects with hip fracture? A non-randomized control trial

Objectives

The effects of a rehabilitation program on static balance, mobility, and strength of lower limbs in elderly fallers operated after a hip fracture and non-operated were studied.

Methods

Ninety-one elderly (>65 years) were divided in two groups, the Operated Group (OG, 43 fallers) and the Non-Operated Group (NOG, 48 fallers). Posture during bipedal stance (30s), mobility (Up-and-Go, Falls Efficacy Scale, Berg Balance Scale) and isokinetic strength of several muscular groups in both limbs were evaluated before and after a rehabilitation intervention, consisting in 20 sessions (3 sessions/week) including kinesiotherapy and occupational therapy.

Results

After intervention, the average velocity of Center of Pressure displacement decreased significantly for OG and NOG (p<0.005). Similarly, all other variables describing static balance, mobility (p<0.05) and isokinetic strength (p<0.005) were improved significantly for both groups.

Conclusions

The applied intervention led to improvement in static balance, mobility, and strength of lower limbs after hip fracture. Physical and Rehabilitation Medicine physicians should prescribe evidence-based rehabilitation protocols in elderly fallers because they could show just as remarkable improvements as non-operated patients when the program is carefully designed.

A systematic review of the effectiveness of Pilates on pain, disability, physical function, and quality of life in older adults with chronic musculoskeletal conditions

OBJECTIVES

This systematic review aims to evaluate the effectiveness and delivery of Pilates to reduce pain and disability and to improve physical function and quality of life in middle-aged to older adults with a range of chronic musculoskeletal conditions.

METHODS

Searches were conducted using CENTRAL, CINAHL, SCOPUS, Pubmed, PsycInfo, Web of Science Core Collection and Google Scholar. Inclusion criteria were controlled trials and observational studies, population mean age 50 years and over with chronic musculoskeletal conditions, using mat-based Pilates exercise. Outcomes included pain, disability, physical function and quality of life.

RESULTS

Seven studies were included, with a combined total sample of 397 participants (73% female). Pilates was significantly effective (p ≤ 0.05) for reducing back pain, neck pain and pain associated with knee osteoarthritis and osteoporosis. Additional significant disability, physical functioning and quality of life effects were found for back pain, osteoporosis, and knee OA. Overall Pilates was as effective as other exercise. Adherence to group exercise was good, but poor for home exercise. No significant adverse effects were reported.

CONCLUSION

Pilates is a safe and effective exercise intervention for adults over 50 with a diverse range of musculoskeletal conditions which may otherwise put them at risk of becoming sedentary. Although no overall significant superiority was found over other exercise, participants reported psychosocial benefits particular to the Pilates group exercise, with enjoyment a possible positive factor in adherence. Further research on Pilates exercises for various pathologies could inform teaching and improve engagement with older adults, including those with chronic conditions.

Promoting Generalized Learning in Balance Recovery Interventions

Recent studies have shown balance recovery can be enhanced via task-specific training, referred to as perturbation-based balance training (PBT). These interventions rely on principles of motor learning where repeated exposure to task-relevant postural perturbations results in more effective compensatory balance responses. Evidence indicates that compensatory responses trained using PBT can be retained for many months and can lead to a reduction in falls in community-dwelling older adults. A notable shortcoming with PBT is that it does not transfer well to similar but contextually different scenarios (e.g., falling sideways versus a forward trip). Given that it is not feasible to train all conditions in which someone could fall, this limited transfer presents a conundrum; namely, how do we best use PBT to appropriately equip people to deal with the enormous variety of fall-inducing scenarios encountered in daily life? In this perspective article, we draw from fields of research that explore how general learning can be promoted. From this, we propose a series of methods, gleaned from parallel streams of research, to inform and hopefully optimize this emerging field where people receive training to specifically improve their balance reactions.

Physiotherapy rehabilitation for osteoporotic vertebral fracture-a randomised controlled trial and economic evaluation (PROVE trial)

The trial compared three physiotherapy approaches: manual or exercise therapy compared with a single session of physiotherapy education (SSPT) for people with osteoporotic vertebral fracture(s). At 1 year, there were no statistically significant differences between the groups meaning there is inadequate evidence to support manual or exercise therapy.

INTRODUCTION

To evaluate the clinical and cost-effectiveness of different physiotherapy approaches for people with osteoporotic vertebral fracture(s) (OVF).

METHODS

>Prospective, multicentre, adaptive, three-arm randomised controlled trial. Six hundred fifteen adults with back pain, osteoporosis, and at least 1 OVF participated.

INTERVENTIONS

7 individual physiotherapy sessions over 12 weeks focused on either manual therapy or home exercise compared with a single session of physiotherapy education (SSPT). The co-primary outcomes were quality of life and back muscle endurance measured by the QUALEFFO-41 and timed loaded standing (TLS) test at 12 months.

RESULTS

At 12 months, there were no statistically significant differences between groups. Mean QUALEFFO-41: - 1.3 (exercise), - 0.15 (manual), and - 1.2 (SSPT), a mean difference of - 0.2 (95% CI, - 3.2 to 1.6) for exercise and 1.3 (95% CI, - 1.8 to 2.9) for manual therapy. Mean TLS: 9.8 s (exercise), 13.6 s (manual), and 4.2 s (SSPT), a mean increase of 5.8 s (95% CI, - 4.8 to 20.5) for exercise and 9.7 s (95% CI, 0.1 to 24.9) for manual therapy. Exercise provided more quality-adjusted life years than SSPT but was more expensive. At 4 months, significant changes above SSPT occurred in endurance and balance in manual therapy, and in endurance for those ≤ 70 years, in balance, mobility, and walking in exercise.

CONCLUSIONS

Adherence was problematic. Benefits at 4 months did not persist and at 12 months, we found no significant differences between treatments. There is inadequate evidence a short physiotherapy intervention of either manual therapy or home exercise provides long-term benefits, but arguably short-term benefits are valuable.

The Application of PRECEDE Model on Preventing Osteoporosis in Women

The aim of this study is investigating the efficiency of educational intervention based on PRECEDE model on promotion of osteoporosis prevention behaviors in women. This quasi-experimental study was conducted on 200 women registered in two health centers of Fasa city, Fars province, Iran in 2017 to 2018. A questionnaire including items evaluating demographic information and PRECEDE model constructs was used for measuring nutrition and walking performance of studied women in osteoporosis prevention before and 12 months after intervention. Bone mineral density (BMD) was recorded at the lumbar spine and femur before and 12 months after intervention. One year after intervention, the intervention group showed a significant increase in knowledge, attitude, self-efficacy, reinforcing factors, enabling factors, nutrition, and walking performance compared to the control group. Also, the value of lumbar spine and hip BMD T-Score of the intervention group was increased, while this value was reduced in the control group. Our findings showed that educational interventions based on PRECEDE model can positively affect prevention behaviors from osteoporosis by improving subjects' knowledge, attitude, enabling factors (resources such as health care access and services that can provide motivation for prevention behaviors from osteoporosis in women), self-efficacy, and reinforcing factors.

Exercise for preventing falls in older people living in the community

BACKGROUND

At least one-third of community-dwelling people over 65 years of age fall each year. Exercises that target balance, gait and muscle strength have been found to prevent falls in these people. An up-to-date synthesis of the evidence is important given the major long-term consequences associated with falls and fall-related injuries OBJECTIVES: To assess the effects (benefits and harms) of exercise interventions for preventing falls in older people living in the community.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, three other databases and two trial registers up to 2 May 2018, together with reference checking and contact with study authors to identify additional studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) evaluating the effects of any form of exercise as a single intervention on falls in people aged 60+ years living in the community. We excluded trials focused on particular conditions, such as stroke.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. Our primary outcome was rate of falls.

MAIN RESULTS

We included 108 RCTs with 23,407 participants living in the community in 25 countries. There were nine cluster-RCTs. On average, participants were 76 years old and 77% were women. Most trials had unclear or high risk of bias for one or more items. Results from four trials focusing on people who had been recently discharged from hospital and from comparisons of different exercises are not described here.Exercise (all types) versus control Eighty-one trials (19,684 participants) compared exercise (all types) with control intervention (one not thought to reduce falls). Exercise reduces the rate of falls by 23% (rate ratio (RaR) 0.77, 95% confidence interval (CI) 0.71 to 0.83; 12,981 participants, 59 studies; high-certainty evidence). Based on an illustrative risk of 850 falls in 1000 people followed over one year (data based on control group risk data from the 59 studies), this equates to 195 (95% CI 144 to 246) fewer falls in the exercise group. Exercise also reduces the number of people experiencing one or more falls by 15% (risk ratio (RR) 0.85, 95% CI 0.81 to 0.89; 13,518 participants, 63 studies; high-certainty evidence). Based on an illustrative risk of 480 fallers in 1000 people followed over one year (data based on control group risk data from the 63 studies), this equates to 72 (95% CI 52 to 91) fewer fallers in the exercise group. Subgroup analyses showed no evidence of a difference in effect on both falls outcomes according to whether trials selected participants at increased risk of falling or not.The findings for other outcomes are less certain, reflecting in part the relatively low number of studies and participants. Exercise may reduce the number of people experiencing one or more fall-related fractures (RR 0.73, 95% CI 0.56 to 0.95; 4047 participants, 10 studies; low-certainty evidence) and the number of people experiencing one or more falls requiring medical attention (RR 0.61, 95% CI 0.47 to 0.79; 1019 participants, 5 studies; low-certainty evidence). The effect of exercise on the number of people who experience one or more falls requiring hospital admission is unclear (RR 0.78, 95% CI 0.51 to 1.18; 1705 participants, 2 studies, very low-certainty evidence). Exercise may make little important difference to health-related quality of life: conversion of the pooled result (standardised mean difference (SMD) -0.03, 95% CI -0.10 to 0.04; 3172 participants, 15 studies; low-certainty evidence) to the EQ-5D and SF-36 scores showed the respective 95% CIs were much smaller than minimally important differences for both scales.Adverse events were reported to some degree in 27 trials (6019 participants) but were monitored closely in both exercise and control groups in only one trial. Fourteen trials reported no adverse events. Aside from two serious adverse events (one pelvic stress fracture and one inguinal hernia surgery) reported in one trial, the remainder were non-serious adverse events, primarily of a musculoskeletal nature. There was a median of three events (range 1 to 26) in the exercise groups.Different exercise types versus controlDifferent forms of exercise had different impacts on falls (test for subgroup differences, rate of falls: P = 0.004, I² = 71%). Compared with control, balance and functional exercises reduce the rate of falls by 24% (RaR 0.76, 95% CI 0.70 to 0.81; 7920 participants, 39 studies; high-certainty evidence) and the number of people experiencing one or more falls by 13% (RR 0.87, 95% CI 0.82 to 0.91; 8288 participants, 37 studies; high-certainty evidence). Multiple types of exercise (most commonly balance and functional exercises plus resistance exercises) probably reduce the rate of falls by 34% (RaR 0.66, 95% CI 0.50 to 0.88; 1374 participants, 11 studies; moderate-certainty evidence) and the number of people experiencing one or more falls by 22% (RR 0.78, 95% CI 0.64 to 0.96; 1623 participants, 17 studies; moderate-certainty evidence). Tai Chi may reduce the rate of falls by 19% (RaR 0.81, 95% CI 0.67 to 0.99; 2655 participants, 7 studies; low-certainty evidence) as well as reducing the number of people who experience falls by 20% (RR 0.80, 95% CI 0.70 to 0.91; 2677 participants, 8 studies; high-certainty evidence). We are uncertain of the effects of programmes that are primarily resistance training, or dance or walking programmes on the rate of falls and the number of people who experience falls. No trials compared flexibility or endurance exercise versus control.

AUTHORS' CONCLUSIONS

Exercise programmes reduce the rate of falls and the number of people experiencing falls in older people living in the community (high-certainty evidence). The effects of such exercise programmes are uncertain for other non-falls outcomes. Where reported, adverse events were predominantly non-serious.Exercise programmes that reduce falls primarily involve balance and functional exercises, while programmes that probably reduce falls include multiple exercise categories (typically balance and functional exercises plus resistance exercises). Tai Chi may also prevent falls but we are uncertain of the effect of resistance exercise (without balance and functional exercises), dance, or walking on the rate of falls.

The effect of group exercises on balance, mobility, and depressive symptoms in older adults with mild cognitive impairment: a randomized controlled trial

OBJECTIVE:

To determine the effects of group exercises on balance, mobility, and depressive symptoms in community-dwelling older adults with mild cognitive impairment.

DESIGN:

Single blinded, randomized, matched pairs clinical trial.

SETTING:

Four primary healthcare units.

SUBJECTS:

Fifty-two sedentary subjects with mild cognitive impairment were paired (age, sex, body mass index, and Addenbrooke's Cognitive Examination Revised score), tested, and then randomized into an intervention group ( n = 26) and a control group ( n = 26).

INTERVENTION:

The intervention group performed strength (ankle weights, elastic bands, and dumbbells) and aerobic exercises (walking) in their communities' public spaces, twice a week (60 minutes each), during 24 weeks. The control group maintained its usual routine.

MAIN MEASURES:

Balance (Berg Balance Scale (BBS)), mobility (Timed Up and Go Test (TUG)), and depressive symptoms (Geriatric Depression Scale-15) were assessed before and after the intervention.

RESULTS:

Before the intervention, the two groups did not differ statistically. After, the intervention group showed significant improvement ( P < 0.05) in balance (before: 53 ± 3; after: 55.1 ± 1.1 points), mobility (before: 10.7 ± 2.9 seconds; after: 8.3 ± 2 seconds), and depressive symptoms (median punctuation (interquartile range) before: 4 (1.8-6); after: 2.5 (1-4)). The control group presented a significant increase in their depressive symptoms (median before: 3.5 (2-7.3); after: 4 (2-5.3)), while their balance and mobility showed no significant modification. Small effect sizes were observed in the intervention group and control group depressive symptoms, as well as in the control group's mobility and balance. Large effect sizes were observed the intervention group's mobility and balance.

CONCLUSION:

Group exercises improved balance, mobility, and depressive symptoms in community-dwelling older adults with mild cognitive impairment.

Effect of Physical Activity on the Quality of Life in Osteoporotic Females Living in Residential Facilities: A Randomized Controlled Trial

BACKGROUND AND PURPOSE

The study aimed to assess the effect of a program of modified Sinaki exercises and Nordic Walking on the life quality in osteoporotic and osteopenic females living in residential care facilities, taking into account their baseline level of activity and risk of falling. The study was designed as a randomized controlled trial.

METHODS

A sample of 91 females 65 to 98 years of age, the residents of Upper Silesian residential care facilities, was randomized into 4 groups. All groups received the same pharmacological treatment. In group 1 (control group), drugs were the only therapy; in group 2, the therapy was enhanced by program of modified Sinaki exercises; group 3 participated in Nordic Walking workout; and group 4 did both Sinaki exercises and Nordic Walking. Locomotor activity of the participants was estimated from pedometer readings. The risk of falling was assessed with the "Timed Up and Go" Test and the Functional Reach Test. With the QUALEFFO-41 questionnaire, the life quality of the participants was evaluated at baseline and after 12 months of intervention.

RESULTS AND DISCUSSION

The study revealed that the studied women were at high risk of falling and that their physical activity was relatively low, likewise the quality of their lives. Their satisfaction with life was reduced by poor health, limited mobility, and the lack of social activities. Life quality improved in all 3 intervention groups, but in the control group, it decreased. The results of Bonferroni's post hoc test pointed to statistically significantly better quality of life in groups 2 (P = .01) and 4 (P < .01).

CONCLUSION

Both modified Sinaki exercises and Nordic Walking significantly improved the participants' quality of life, but the most effective therapeutically was the combination of both these forms of physical activity.

Behavioural and objective vestibular assessment in persons with osteoporosis and osteopenia: a preliminary investigation

INTRODUCTION

Calcium is vital for the functioning of the inner ear hair cells as well as for the neurotransmitter release that triggers the generation of a nerve impulse. A reduction in calcium level could therefore impair the peripheric vestibular functioning. However, the outcome of balance assessment has rarely been explored in cases with osteopenia and osteoporosis, the medical conditions associated with reduction in calcium levels.

OBJECTIVE

The present study aimed to investigate the impact of osteopenia and osteoporosis on the outcomes of behavioural and objective vestibular assessment tests.

METHODS

The study included 12 individuals each in the healthy control group and osteopenia group, and 11 individuals were included in the osteoporosis group. The groups were divided based on the findings of bone mineral density. All the participants underwent behavioural tests (Fukuda stepping, tandem gait and subjective visual vertical) and objective assessment using cervical and ocular vestibular evoked myogenic potentials.

RESULTS

A significantly higher proportion of the individuals in the two clinical groups' demonstrated abnormal results on the behavioural balance assessment tests (p<0.05) than the control group. However, there was no significant difference in latencies or amplitude of cervical vestibular evoked myogenic potential and oVEMP between the groups. The proportion of individuals with absence of ocular vestibular evoked myogenic potential was significantly higher in the osteoporosis group than the other two groups (p<0.05).

CONCLUSION

The findings of the present study confirm the presence of balance-related deficits in individuals with osteopenia and osteoporosis. Hence the clinical evaluations should include balance assessment as a mandatory aspect of the overall audiological assessment of individuals with osteopenia and osteoporosis.

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.

Exercise to improve functional outcomes in persons with osteoporosis: a systematic review and meta-analysis

Osteoporosis affects many aspects of daily life. The aim of this systematic review was to assess the effects of exercise interventions on functional outcomes in persons with osteoporosis, in comparison with controls.

METHODS

Four databases were searched and yielded 1587 citations. Two reviewers independently determined study eligibility, rated risk of bias, appraised methodological quality of studies, and resolved discordance by consensus.

RESULTS

A total of 28 studies examining 2113 participants met inclusion criteria; 25 studies were suitable for meta-analyses. Four categories of exercise were identified using the ProFaNE taxonomy. After removing studies with high risk of bias and sorting them into intervention sub-types, we were able to sufficiently reduce the heterogeneity. The standardized mean difference (SMD) favored multicomponent exercise for mobility (- 0.56, 95% CI [- 0.81, - 0.32], p = 0.06, I² = 51%); balance (0.50, 95% CI [0.27, 0.74], p = 0.28, I² = 21%); and self-reported measures of functioning (- 0.69, 95% CI [- 1.04, - 0.34], p = 0.02, I² = 61%). Trials were judged at low or unclear risk of selection bias, indicating inadequate reporting and at high risk of performance bias due to lack of participant blinding. The mean methodological quality rating of the studies was 63.5% indicating moderate quality.

CONCLUSIONS

A multicomponent exercise program of high-speed training combined with simulated functional tasks is promising to enhance functional outcomes. Due to substantial clinical heterogeneity of the target groups and specific demands of exercise modes, it is unclear which exercise program is optimal.

Quality of Life in Patients with Osteoporotic Vertebral Compression Fractures

BACKGROUND

This study aimed to evaluate quality of life (QOL) using the EuroQOL-5 dimensions (EQ-5D) index and to examine factors affecting QOL in patients with an osteoporotic vertebral compression fracture (OVCF).

METHODS

This ambispective study used a questionnaire interview. Patients over 50 years old with an OVCF at least 6 months previously were enrolled. Individual results were used to calculate the EQ-5D index. Statistical analysis was performed, and factors related to QOL were examined.

RESULTS

Of 196 patients in the study, 84.2% were female, with an average age of 72.7 years. There were 66 (33.7%) patients with multilevel fractures. Conservative management was used in 75.0% of patients, and 56.1% received anti-osteoporosis treatment. The mean EQ-5D index was 0.737±0.221 and was significantly correlated with the Oswestry disability index score (correlation coefficient -0.807, P<0.001). The EQ-5D index was significantly correlated with age (Spearman's rho=-2.0, P=0.005), treatment method (P=0.005), and history of fracture (P=0.044) on univariate analysis and with conservative treatment (P<0.001) and osteoporotic treatment (P=0.017) on multivariate analysis.

CONCLUSIONS

OVCF markedly lowers QOL in several dimensions for up to 12 months, even in patients who have healed. Treatment of osteoporosis and conservative treatment methods affect QOL and should be considered in OVCF management.

Physical exercise programs at Basic Healthcare Units decrease body fat and improve the functional capacity of women over 50 years old

This study verified the effects of a physical exercise program performed at Basic Healthcare Units on the body composition and functional capacity of women over 50 years old and to compare these variables according to age. Forty-eight women (age, 65.4±7.3 years) were assessed. The program lasted 20 weeks, and was conducted 2 times per week, 60 min/day. Body mass and height were collected and body mass index (BMI) was calculated. Bioelectrical impedance was used to estimate fat mass and fat free mass. Functional capacities: handgrip test, Timed Up and Go (TUG) test, and Guralnick test were assessment. Weight (68.7±12.5 [pre]×66.8±12.5 [post], P<0.001), BMI (28.5±4.1 kg/m² [pre]×27.6±4.0 kg/m² [post], P<0.001), and fat mass (28.4±7.8 kg [pre]×26.4±7.3 kg [post], P<0.001) were decreased. For functional capacity, handgrip (21.2±5.8 kg [pre]×22.9±6.9 kg [post], P=0.014), lower limb strength (12.0±3.0 sec [pre]×8.5±2.2 sec [post], P<0.001), TUG (8.4±1.5 sec [pre]×7.6±1.1 se [post], P<0.001) and Guralnik tests (10.6±1.6 [pre]×11.8±0.5 [post], P<0.001) were improved. 20 weeks of exercise program performed at Basic Healthcare Units decreased body fat and improvement of functional capacity of women over 50 years old and there was difference according to age only on the body composition variables.

Facilitators and barriers to exercise adherence in patients with osteopenia and osteoporosis: a systematic review

The aim of this study was to categorize the facilitators and barriers of exercise and identify methods to promote exercise adherence in the osteoporosis population. Despite the fair methodological quality of included randomized controlled trials (RCTs), less than 75 % identified facilitators and barriers to exercise. Methods to promote and measure exercise adherence were poorly reported.

INTRODUCTION

Several studies have shown exercise to be successful in maintaining or increasing BMD in individuals with low bone mass. Yet, adherence to exercise is poor, with 50 % of those registered in an exercise program dropping out within the first 6 months, lack of time being the number one barrier in many populations. However, in the osteoporosis population, the main facilitator and barrier to exercise is still unclear. The aim of this study is to examine the extent to which RCTs reported the facilitators and the barriers to exercise and identified methods to promote adherence to an exercise program.

METHODS

PubMed, CINHAL, EMBASE, and the Cochrane Review were queried using a predefined search criterion, and the resulting citations were imported into DistillerSR. Screening was carried out by two independent reviewers, and articles were included in the analysis by consensus. The methodological quality of included studies was assessed using the PEDro scale.

RESULTS

Fifty-four RCTs examining exercise interventions in patients with osteopenia or osteoporosis were included. A spectrum of facilitators and barriers to exercise for osteoporotic patients were identified; however, no one facilitator was more frequently reported than the other. The most commonly reported barriers were lack of time and transportation. In most RCTs, methods to promote and measure exercise adherence were unsatisfactory. Of the 54 papers, 72 % reported an adherence rate to an exercise program; the lowest reported rate was 51.7 %, and the highest 100 %.

CONCLUSIONS

Most RCTs found were of fair quality; however, less than three quarters identified facilitators and barriers to exercise. Reporting of methods to promote and measure exercise adherence were low. Future work should be directed toward identifying major facilitators and barriers to exercise adherence within RCTs. Only then can methods be identified to leverage facilitators and overcome barriers, thus strengthening the evidence for efficacy of optimal interventional exercise programs. This review has been registered in PROSPERO under registration number CRD42016039941.

Effects of Evidence-Based Fall Reduction Programing on the Functional Wellness of Older Adults in a Senior Living Community: A Clinical Case Study

BACKGROUND

Older adults at a high risk of falls may be referred to a physical therapist. A physical therapy episode of care is designed for the transition of an older adult from a high fall risk to a moderate to low fall risk. However, these episodes of care are limited in time and duration. There is compelling evidence for the efficacy of group-based exercise classes to address risk, and transitioning an older adult from physical therapy to a group-based program may be an effective way to manage risk through the continuum of care.

OBJECTIVES

The purpose of this study was to translate research findings into a "real world" setting, and demonstrate the efficacy of integrating evidence-based fall prevention exercises into pre-existing exercise classes at a senior living facility as a "proof of concept" model for future programing.

METHODS

Twenty-four participants aged 65 years and older living in a senior living community and the community were stratified into group-based exercise classes. Cutoff scores from functional outcome measures were used to stratify participants. Exercises from The Otago Exercise Program were implemented into the classes. Functional outcome measures collected included the 10-Meter Walk Test, 30-Second Sit to Stand, and Timed Up and Go (TUG). Number of falls, hospitalizations, and physical therapy episodes of care were also tracked. Data were compared to a control group in a different senior living community that offered classes with similar exercises aimed at improving strength and mobility. The classes were taught by an exercise physiologist and were of equal duration and frequency.

RESULTS

Participants demonstrated significant improvements in all functional outcome measures. TUG mean improved from 13.5 to 10.4 s (p = 0.034). The 30-Second Sit to Stand mean improved from 10.5 to 13.4 (p = 0.002). The 10-Meter Walk Test improved from 0.81 to 0.98 m/s (p < 0.0001). Participants did not experience any falls or hospitalizations, and two participants required physical therapy episodes of care.

CONCLUSION

Implementing an evidence-based fall reduction program into a senior living program has a positive effect on strength, balance, fall risk, gait speed, fall rate, hospitalizations, and amount of physical therapy intervention.

Exercise as medicine - evidence for prescribing exercise as therapy in 26 different chronic diseases

This review provides the reader with the up-to-date evidence-based basis for prescribing exercise as medicine in the treatment of 26 different diseases: psychiatric diseases (depression, anxiety, stress, schizophrenia); neurological diseases (dementia, Parkinson's disease, multiple sclerosis); metabolic diseases (obesity, hyperlipidemia, metabolic syndrome, polycystic ovarian syndrome, type 2 diabetes, type 1 diabetes); cardiovascular diseases (hypertension, coronary heart disease, heart failure, cerebral apoplexy, and claudication intermittent); pulmonary diseases (chronic obstructive pulmonary disease, asthma, cystic fibrosis); musculo-skeletal disorders (osteoarthritis, osteoporosis, back pain, rheumatoid arthritis); and cancer. The effect of exercise therapy on disease pathogenesis and symptoms are given and the possible mechanisms of action are discussed. We have interpreted the scientific literature and for each disease, we provide the reader with our best advice regarding the optimal type and dose for prescription of exercise.

State of the Art Review: Physical Activity and Older Adults

Physical activity is an important component of a healthy lifestyle for all adults and especially for older adults. Using information from the updated 2008 Physical Activity Guidelines, 3 dimensions of physical activity are identified for older adults. These include increasing aerobic activity, increasing muscle-strengthening activity, and reducing sedentary or sitting behavior. Although the overall goal of the physical activity recommendations is to prevent chronic diseases and conditions from developing, many older adults are already affected. Therefore, suggested types of physical activity are described for specific diseases and conditions that are designed to mediate the condition or prevent additional disability. Finally, barriers to participation in physical activity specific to older adults are described, and possible solutions offered. Encouraging older adults to continue or even start a physical activity program can result in major health benefits for these individuals.

Application of the health belief model and social cognitive theory for osteoporosis preventive nutritional behaviors in a sample of Iranian women

BACKGROUND

Osteoporosis is the most common metabolic bone disease. The purpose of this study is to investigate the health belief model (HBM) and social cognitive theory (SCT) for osteoporosis preventive nutritional behaviors in women.

MATERIALS AND METHODS

In this quasi-experimental study, 120 patients who were women and registered under the health centers in Fasa City, Fars Province, Iran were selected. A questionnaire consisting of HBM constructs and the constructs of self-regulation and social support from SCT was used to measure nutrition performance. Bone mineral density was recorded at the lumbar spine and femur. The intervention for the experimental group included 10 educational sessions of 55-60 min of speech, group discussion, questions and answers, as well as posters and educational pamphlets, film screenings, and PowerPoint displays. Data were analyzed using SPSS 19 via Chi-square test, independent t-test, and repeated measures analysis of variance (ANOVA) at a significance level of 0.05.

RESULTS

After intervention, the experimental group showed a significant increase in the HBM constructs, self-regulation, social support, and nutrition performance, compared to the control group. Six months after the intervention, the value of lumbar spine bone mineral density (BMD) T-score increased to 0.127 in the experimental group, while it reduced to -0.043 in the control group. The value of the hip BMD T-score increased to 0.125 in the intervention group, but it decreased to -0.028 in the control group.

CONCLUSIONS

This study showed the effectiveness of HBM and constructs of self-regulation and social support on adoption of nutrition behaviors and increase in the bone density to prevent osteoporosis.

Effects of an Osteoporosis Prevention Program Based on Health Belief Model Among Females

Background:

Several studies reported the efficacy of osteoporosis prevention interventions in improvement of people’s preventive behaviors. However, there are reports that the interventions were not successful in altering osteoporosis health beliefs and preventive behaviors.

Objectives:

The current study aimed to assess the effect of a program based on health beliefs model (HBM) on females’ health beliefs and performances about osteoporosis preventive behaviors.

Patients and Methods:

This quasi-experimental study was conducted on 120 patients registered in two healthcare centers of Fasa, Fars Province, Iran in 2014. A questionnaire including demographic information and HBM constructs was employed to measure the females’ beliefs regarding nutrition and walking performance in prevention of osteoporosis bone mineral density (BMD) measured at the lumbar spine and femur before, immediately after the intervention, and six months after the intervention. Data were analyzed using Chi-square, independent samples t-, Mann-Whitney U tests and repeated measures ANOVA.

Results:

Immediately and six months after the intervention, a significant increase was found in the intervention group’s health beliefs, nutrition, and walking performances to prevent osteoporosis. Six months after the intervention, lumbar spine BMD T-score increased to 0.127 ± 0.061 in the intervention group but reduced to -0.043 ± 0.059 in the control group. Also, hip BMD T-score increased to 0.125 ± 0.088 in the intervention group, but decreased to -0.028 ± 0.052 in control group.

Conclusions:

The current study showed the effectiveness of HBM in adoption of nutrition and walking behaviors as well as the increase of bone density to prevent osteoporosis.

Atividade física na vida diária e densidade mineral óssea em mulheres idosas

INTRODUÇÃO: o rápido envelhecimento da população contemporânea tem influenciado no desenvolvimento de estratégias para a prevenção da osteoporose em idosos. A atividade física diária é vista como uma possível estratégia para aumentar a massa óssea e ajudar a prevenir a perda óssea em pessoas idosas. No entanto, é essencial saber a quantidade mínima ou a intensidade adequada de atividade física que produza o aumento da massa óssea em mulheres idosas.OBJETIVO: analisar, durante uma semana, a relação entre a quantidade e a intensidade da atividade física diária com a densidade mineral óssea (DMO) da mão, por meio da quantificação de atividade física diária em idosas.MÉTODOS: a amostra do estudo foi composta por 24 mulheres (idade 66-78 anos), que realizaram atividade física, durante 7 dias, com um gravador da aceleração dos movimentos do corpo em seu pulso, para uma quantificação individual da atividade física. Para medir a densidade mineral óssea da mão direita foi utilizada a técnica de dupla absorção de raios-X (DXA).RESULTADOS: uma relação significativa entre a prática semanal e o T-score (r = 0,99) e a prática semanal horizontal e o T-score (r = 0,99) foi encontrada no osso normal e no grupo ósseo com osteoporose, respectivamente. A relação entre T-score e a quantidade de atividade física não era clara em ambos os grupos.CONCLUSÃO: na amostra analisada, foi encontrada uma associação positiva entre a maior qualidade do osso da mão e a intensidade mais elevada de atividade física. A combinação de absorciometria acelerometria e de raios-X na mão obteve resultados semelhantes ao encontrados com outros métodos menos acessíveis.

The effect of exercise and education on fear of falling in elderly women with osteoporosis and a history of vertebral fracture: results of a randomized controlled trial

This article explores the effect of a group-based exercise program and an educational session on the fear of falling among 89 women with osteoporosis and a history of vertebral fracture. This randomized clinical trial showed that the intervention had a positive and durable effect on the fear of falling.

INTRODUCTION

The aim of this study was to evaluate the effect of an intervention on fear of falling in women with osteoporosis and a history of vertebral fracture.

METHODS

The study was a parallel-group randomized clinical trial with a blinded assessor. The participants were 89 community-dwelling elderly women with osteoporosis and a history of vertebral fracture. The intervention group (IT, n = 47) received a 3-month group-based circuit exercise program combined with a 3-h educational session focusing on the reduction of the risk of falls and challenges specific to osteoporosis and vertebral fractures. The control group (CT, n = 42) continued with their usual activities. Clinical outcomes were assessed at baseline, postintervention and 12 months after randomization. This article reports on the secondary outcome Falls Efficacy Scale-International (FES-I) from a previously reported trial.

RESULTS

We found a significantly better result for the IT group compared with the CT group, both at 3 months (p = 0.004) and 12 months (p < 0.001) follow-up. The effect size at 3 months was small (0.4) and at 12 months moderate (0.7). Multiple regression analysis confirmed the effect of the intervention.

CONCLUSION

The intervention had a positive and durable effect on fear of falling as measured with the FES-I.

The effectiveness of physical therapist-administered group-based exercise on fall prevention: a systematic review of randomized controlled trials

BACKGROUND

Falls are a verified cause of morbidity and mortality in adults older than 65 years. Exercise under the direction of a physical therapist has been shown to reduce the risk of falls in older adults; however, it is not clear whether physical therapist-directed group-based exercise could produce similar results.

PURPOSE

The purpose of this systematic review was to summarize the evidence on the effectiveness of physical therapist-administered group-based exercise when compared with various controls for falls prevention and improvement of quality of life.

METHODS

A computerized search of PubMed and CINAHL was performed. An exhaustive hand search was also performed of the references of all full-text articles. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed for this review. Studies were included if they met the following criteria: (1) comparison of group-based exercise led by a physical therapist to a control group; (2) ambulatory elderly men or women, aged 65 years or older; (3) subjects in the community or institutional setting; (4) the use of 1 or more outcome measures related to functional balance and/or quality of life; (5) randomized controlled or clinical trials; and (6) published in English, between December 1, 2001, and June 7, 2012. The PEDro scale was used to assess the quality of each study included in this review.

RESULTS

The computerized search strategy and hand search revealed 213 potential articles, 10 of which met the inclusion criteria. After assessment with the PEDro scale, 8 of these were considered high-quality studies (score > 6/10). Seven studies compared group-based exercise to a nonexercise control group, while 3 studies compared group-based exercise with a physical therapist-prescribed home exercise program. Outcomes measured include fall rate, balance, physical performance, health-related quality of life, and fear of falling.

DISCUSSION

When group-based exercise was compared with no intervention, group-based exercise was found to be more effective in decreasing fall frequency, increase balance, and improve quality of life. When compared with a physical therapist-prescribed home exercise program, the group-based exercise results were not statistically different but showed improvements in some quality of life and physical functioning measures. There is also some evidence to suggest that group-based exercise promotes greater patient satisfaction and exercise adherence.

CONCLUSION

There is preliminary evidence to suggest that the group-based exercise is effective for falls prevention, quality-of-life enhancement, and balance improvements in the older adults comparable with traditional home exercise programs.

The challenge of obtaining information necessary for multi-criteria decision analysis implementation: the case of physiotherapy services in Canada

BACKGROUND

As fiscal constraints dominate health policy discussions across Canada and globally, priority-setting exercises are becoming more common to guide the difficult choices that must be made. In this context, it becomes highly desirable to have accurate estimates of the value of specific health care interventions.Economic evaluation is a well-accepted method to estimate the value of health care interventions. However, economic evaluation has significant limitations, which have lead to an increase in the use of Multi-Criteria Decision Analysis (MCDA). One key concern with MCDA is the availability of the information necessary for implementation. In the Fall 2011, the Canadian Physiotherapy Association embarked on a project aimed at providing a valuation of physiotherapy services that is both evidence-based and relevant to resource allocation decisions. The framework selected for this project was MCDA. We report on how we addressed the challenge of obtaining some of the information necessary for MCDA implementation.

METHODS

MCDA criteria were selected and areas of physiotherapy practices were identified. The building up of the necessary information base was a three step process. First, there was a literature review for each practice area, on each criterion. The next step was to conduct interviews with experts in each of the practice areas to critique the results of the literature review and to fill in gaps where there was no or insufficient literature. Finally, the results of the individual interviews were validated by a national committee to ensure consistency across all practice areas and that a national level perspective is applied.

RESULTS

Despite a lack of research evidence on many of the considerations relevant to the estimation of the value of physiotherapy services (the criteria), sufficient information was obtained to facilitate MCDA implementation at the local level.

CONCLUSIONS

The results of this research project serve two purposes: 1) a method to obtain information necessary to implement MCDA is described, and 2) the results in terms of information on the benefits provided by each of the twelve areas of physiotherapy practice can be used by decision-makers as a starting point in the implementation of MCDA at the local level.

The impact of asymptomatic vertebral fractures on quality of life in older community-dwelling women: the São Paulo Ageing & Health Study

OBJECTIVES

The aim of this study was to investigate the impact of asymptomatic vertebral fractures on the quality of life in older women as part of the Sao Paulo Ageing & Health Study.

METHODS

This study was a cross-sectional study with a random sample of 180 women 65 years of age or older with or without vertebral fractures. The Quality of Life Questionnaire of the European Foundation for Osteoporosis was administered to all subjects. Anthropometric data were obtained by physical examination, and the body mass index was calculated. Lateral thoracic and lumbar spine X-ray scans were obtained to identify asymptomatic vertebral fractures using a semi-quantitative method.

RESULTS

Women with asymptomatic vertebral fractures had lower total scores [61.4(15.3) vs. 67.1(14.2), p = 0.03] and worse physical function domain scores [69.5(20.1) vs. 77.3(17.1), p = 0.02] for the Quality of Life Questionnaire of the European Foundation for Osteoporosis compared with women without fractures. The total score of this questionnaire was also worse in women classified as obese than in women classified as overweight or normal. High physical activity was related to a better total score for this questionnaire (p = 0.01). Likewise, lower physical function scores were observed in women with higher body mass index values (p<0.05) and lower physical activity levels (p<0.05). Generalized linear models with gamma distributions and logarithmic link functions, adjusted for age, showed that lower total scores and physical function domain scores for the Quality of Life Questionnaire of the European Foundation for Osteoporosis were related to a high body mass index, lower physical activity, and the presence of vertebral fractures (p<0.05).

CONCLUSION

Vertebral fractures are associated with decreased quality of life mainly physical functioning in older community-dwelling women regardless of age, body mass index, and physical activity. Therefore, the results highlight the importance of preventing and controlling asymptomatic vertebral fractures to reduce their impact on quality of life among older women.

Quality of life measurements in patients with osteoporosis and fractures

To review all specific questionnaires regarding quality of life in osteoporosis and to describe their distinctive indications, we searched Medline, the Scientific Electronic Library Online database, and the Latin-American and Caribbean Health Sciences Literature database. Nine specific questionnaires related to osteoporosis quality of life were found: 1) the Women's Health Questionnaire, 2) Osteoporosis Quality of Life Questionnaire, 3) Osteoporosis Assessment Questionnaire, 4) Osteoporosis Functional Disability Questionnaire, 5) Quality of Life Questionnaire of the European Foundation for Osteoporosis, 6) Osteoporosis-Targeted Quality of Life Questionnaire, 7) Japanese Osteoporosis Quality of Life Questionnaire, 8) the 16-item Assessment of Health-Related Quality of Life in Osteoporosis, and 9) the Quality of Life Questionnaire in Osteoporosis (QUALIOST™). The Quality of Life Questionnaire of the European Foundation for Osteoporosis is the osteoporosis-specific questionnaire most commonly used in the literature. The Quality of Life Questionnaire of the European Foundation for Osteoporosis and the Osteoporosis Quality of Life Questionnaire are targeted more toward fracture assessment, and the Osteoporosis Functional Disability Questionnaire can be used for longitudinal studies involving exercise. In the present study, the authors summarize all of the specific questionnaires for osteoporosis and demonstrate that these questionnaires should be selected based on the objectives to be evaluated. Osteoporosis-specific quality of life questionnaires should be validated in the language of the country of origin before being used.

Interventions for preventing falls in older people living in the community

BACKGROUND

Approximately 30% of people over 65 years of age living in the community fall each year. This is an update of a Cochrane review first published in 2009.

OBJECTIVES

To assess the effects of interventions designed to reduce the incidence of falls in older people living in the community.

SEARCH METHODS

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (February 2012), CENTRAL (The Cochrane Library 2012, Issue 3), MEDLINE (1946 to March 2012), EMBASE (1947 to March 2012), CINAHL (1982 to February 2012), and online trial registers.

SELECTION CRITERIA

Randomised trials of interventions to reduce falls in community-dwelling older people.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed risk of bias and extracted data. We used a rate ratio (RaR) and 95% confidence interval (CI) to compare the rate of falls (e.g. falls per person year) between intervention and control groups. For risk of falling, we used a risk ratio (RR) and 95% CI based on the number of people falling (fallers) in each group. We pooled data where appropriate.

MAIN RESULTS

We included 159 trials with 79,193 participants. Most trials compared a fall prevention intervention with no intervention or an intervention not expected to reduce falls. The most common interventions tested were exercise as a single intervention (59 trials) and multifactorial programmes (40 trials). Sixty-two per cent (99/159) of trials were at low risk of bias for sequence generation, 60% for attrition bias for falls (66/110), 73% for attrition bias for fallers (96/131), and only 38% (60/159) for allocation concealment.Multiple-component group exercise significantly reduced rate of falls (RaR 0.71, 95% CI 0.63 to 0.82; 16 trials; 3622 participants) and risk of falling (RR 0.85, 95% CI 0.76 to 0.96; 22 trials; 5333 participants), as did multiple-component home-based exercise (RaR 0.68, 95% CI 0.58 to 0.80; seven trials; 951 participants and RR 0.78, 95% CI 0.64 to 0.94; six trials; 714 participants). For Tai Chi, the reduction in rate of falls bordered on statistical significance (RaR 0.72, 95% CI 0.52 to 1.00; five trials; 1563 participants) but Tai Chi did significantly reduce risk of falling (RR 0.71, 95% CI 0.57 to 0.87; six trials; 1625 participants).Multifactorial interventions, which include individual risk assessment, reduced rate of falls (RaR 0.76, 95% CI 0.67 to 0.86; 19 trials; 9503 participants), but not risk of falling (RR 0.93, 95% CI 0.86 to 1.02; 34 trials; 13,617 participants).Overall, vitamin D did not reduce rate of falls (RaR 1.00, 95% CI 0.90 to 1.11; seven trials; 9324 participants) or risk of falling (RR 0.96, 95% CI 0.89 to 1.03; 13 trials; 26,747 participants), but may do so in people with lower vitamin D levels before treatment.Home safety assessment and modification interventions were effective in reducing rate of falls (RR 0.81, 95% CI 0.68 to 0.97; six trials; 4208 participants) and risk of falling (RR 0.88, 95% CI 0.80 to 0.96; seven trials; 4051 participants). These interventions were more effective in people at higher risk of falling, including those with severe visual impairment. Home safety interventions appear to be more effective when delivered by an occupational therapist.An intervention to treat vision problems (616 participants) resulted in a significant increase in the rate of falls (RaR 1.57, 95% CI 1.19 to 2.06) and risk of falling (RR 1.54, 95% CI 1.24 to 1.91). When regular wearers of multifocal glasses (597 participants) were given single lens glasses, all falls and outside falls were significantly reduced in the subgroup that regularly took part in outside activities. Conversely, there was a significant increase in outside falls in intervention group participants who took part in little outside activity.Pacemakers reduced rate of falls in people with carotid sinus hypersensitivity (RaR 0.73, 95% CI 0.57 to 0.93; three trials; 349 participants) but not risk of falling. First eye cataract surgery in women reduced rate of falls (RaR 0.66, 95% CI 0.45 to 0.95; one trial; 306 participants), but second eye cataract surgery did not.Gradual withdrawal of psychotropic medication reduced rate of falls (RaR 0.34, 95% CI 0.16 to 0.73; one trial; 93 participants), but not risk of falling. A prescribing modification programme for primary care physicians significantly reduced risk of falling (RR 0.61, 95% CI 0.41 to 0.91; one trial; 659 participants).An anti-slip shoe device reduced rate of falls in icy conditions (RaR 0.42, 95% CI 0.22 to 0.78; one trial; 109 participants). One trial (305 participants) comparing multifaceted podiatry including foot and ankle exercises with standard podiatry in people with disabling foot pain significantly reduced the rate of falls (RaR 0.64, 95% CI 0.45 to 0.91) but not the risk of falling.There is no evidence of effect for cognitive behavioural interventions on rate of falls (RaR 1.00, 95% CI 0.37 to 2.72; one trial; 120 participants) or risk of falling (RR 1.11, 95% CI 0.80 to 1.54; two trials; 350 participants).Trials testing interventions to increase knowledge/educate about fall prevention alone did not significantly reduce the rate of falls (RaR 0.33, 95% CI 0.09 to 1.20; one trial; 45 participants) or risk of falling (RR 0.88, 95% CI 0.75 to 1.03; four trials; 2555 participants).No conclusions can be drawn from the 47 trials reporting fall-related fractures.Thirteen trials provided a comprehensive economic evaluation. Three of these indicated cost savings for their interventions during the trial period: home-based exercise in over 80-year-olds, home safety assessment and modification in those with a previous fall, and one multifactorial programme targeting eight specific risk factors.

AUTHORS' CONCLUSIONS

Group and home-based exercise programmes, and home safety interventions reduce rate of falls and risk of falling.Multifactorial assessment and intervention programmes reduce rate of falls but not risk of falling; Tai Chi reduces risk of falling.Overall, vitamin D supplementation does not appear to reduce falls but may be effective in people who have lower vitamin D levels before treatment.

Medical treatment of osteoporotic vertebral fractures

A vertebral fracture is a serious symptom of osteoporosis. Vertebral fractures cause moderate-to-severe back pain for a shorter or longer duration, increase the risk of a subsequent vertebral fracture approximately four-fold, reduce quality of life significantly and are associated with increased mortality. In order to choose the optimal treatment for the patient, the severity and type of osteoporosis should be investigated. Prevention of new osteoporotic fractures can be accomplished through treatment with both antiresorptive and anabolic treatments. The antiresorptive treatment modalities comprise calcium, vitamin D, bisphosphonates, hormone therapy, selective oestrogen receptor modulators (SERMs), strontium ranelate, receptor activator of NF-kB ligand (RANKL) antibody and calcitonin. The anabolic treatments comprise teriparatide and parathyroid hormone [(PTH)-(1-84)]. Adherence with treatment of osteoporosis is generally poor and therefore once the choice of treatment has been made and the patient has been instructed properly, long-term adherence to the treatment should be secured through information and regular control visits.

Balance training reduces fear of falling and improves dynamic balance and isometric strength in institutionalised older people: a randomised trial

QUESTION

What is the effect of a balance training protocol with the Biodex Balance System in institutionalised older people with fear of falling?

DESIGN

Randomised controlled trial with concealed allocation and assessor blinding.

PARTICIPANTS

Forty older people who lived in a nursing home and had fear of falling.

INTERVENTION

The experimental group completed a 12-week balance training protocol based on balancing/rebalancing training with the Biodex Balance System, with two sessions per week. During the training period, participants in both groups received the same multidisciplinary care (such as physiotherapy, occupational therapy and nursing) that they usually received in the nursing home.

OUTCOME MEASURES

The primary outcome was fear of falling (Falls Efficacy Scale International questionnaire). Secondary outcomes were dynamic balance (Fall Risk Test) and isometric strength (torque of knee flexor and extensor isometric strength measured with an isokinetic dynamometer). Outcome measures were taken before and after the training program protocol.

RESULTS

Compared to the control group, the exercise group had significantly greater improvements at 12 weeks in fear of falling (by 8 points, 95% CI 4 to 12), in dynamic balance (by 2 degrees, 95% CI 1 to 3), and in isometric strength of the knee flexors (by 7Nm, 95% CI 3 to 11) and knee extensors (by 7Nm, 95% CI 1 to 13).

CONCLUSION

The training program was feasible and effective in reducing fear of falling and improving dynamic balance and isometric strength in institutionalised older people with fear of falling.

Sensibilidade da Escala de Equilíbrio de Berg em indivíduos com osteoartrite

Este estudo teve objetivo de analisar a sensibilidade e especificidade da Escala de Equilíbrio de Berg (EEB) em detectar o risco de queda em indivíduos com osteoartrite de joelho (OAJ). Verificar a associação entre a capacidade funcional, grau de OAJ, quadro álgico, índice de medo de cair e histórico de queda com o escore da EEB. Participaram 69 indivíduos com OAJ. Foram analisados os pontos de corte 45, 47, 49, 51 e 53 pontos da EEB, quanto à sensibilidade e especificidade do teste. Utilizou-se a escala analógica visual e os questionários WOMAC e Índice de preocupação em cair (FES-I). Os resultados evidenciaram diferença significativa (p=0,001) no escore da EEB entre os indivíduos com OAJ com e sem história de queda. A EEB apresentou correlação com Womac, FES-I, histórico de queda e grau de OAJ. A EEB não apresentou um ponto de corte ideal para indivíduos com OAJ. Contudo, a escala é sensível às diferenças individuais nesta população.

Impact of clinical fractures on health-related quality of life is dependent on time of assessment since fracture: results from the FREEDOM trial

In the Fracture Reduction Evaluation of Denosumab in Osteoporosis Every 6 Months (FREEDOM) study, women with incident clinical fractures reported significant declines in health-related quality of life (HRQoL). The largest declines were observed when the assessment was <3 months post fracture. The largest impact of incident clinical fractures was on physical function, and that of incident clinical vertebral fractures was on back pain.

INTRODUCTION

In the FREEDOM trial, denosumab significantly reduced the risk of new vertebral, hip, and nonvertebral fractures. We evaluated the effect of denosumab on HRQoL and the association between incident clinical fractures and HRQoL.

METHODS

The FREEDOM trial enrolled 7,868 women aged 60-90 years with a total hip and/or lumbar spine BMD T-score <-2.5 and not <-4.0 at either site. Women were randomized to receive denosumab 60 mg or placebo every 6 months, in addition to daily calcium and vitamin D. HRQoL was assessed with the Osteoporosis Assessment Questionnaire-Short Version (OPAQ-SV) at baseline and every 6 months for 36 months. The OPAQ-SV assesses physical function, emotional status, and back pain. Higher scores indicate better health status.

RESULTS

No statistically significant differences in mean change in HRQoL from baseline to end of study were found when comparing treatment groups. Compared with women without any incident fractures during the study, women with incident clinical fractures reported significant declines in physical function (-4.0 vs. -0.5) and emotional status (-5.0 vs. -0.8) at month 36 (P < 0.001 for both). Importantly, time-dependent covariate analyses demonstrated that the largest declines were observed when the assessment was <3 months post fracture. The largest impact of incident clinical fractures was on physical function, and that of incident clinical vertebral fractures was on back pain.

CONCLUSIONS

These findings not only demonstrate that incident clinical fractures impact HRQoL but also contribute new information regarding the impact of these fracture events on HRQoL over time.

Effect of resistance exercises on function in older adults with osteoporosis or osteopenia: a systematic review

PURPOSE

To examine the effect of resistance exercises on self-reported physical function and activities of daily living (ADL) in older adults with osteoporosis or osteopenia.

METHODS

A search of available literature was conducted using PubMed, CINAHL, SPORTDiscus, PEDro, ProQuest Nursing and Allied Health Source, and Cochrane Controlled Trials Register. Studies were included if they involved (1) randomized controlled trials; (2) participants with osteoporosis or osteopenia; (3) resistance exercise as an intervention; and (4) self-report of physical function or ADL. Articles were independently reviewed for quality by two authors using the Physiotherapy Evidence Database (PEDro) scale. Cohen's d effect size was calculated by dividing standardized mean differences by the standard deviation to determine treatment effect in terms of physical function or ADL.

RESULTS

Five full-text articles were selected for inclusion. PEDro scores ranged from 5 to 7 (out of 10). Effect size mean differences as a result of resistance intervention ranged from 0.08 to 1.74, suggesting "trivial" to "large" effects on self-reported physical function and ADL.

CONCLUSION

RESULTS suggest that interventions using resistance training have a beneficial impact on the domains of physical function and ADL in participants with osteoporosis or osteopenia. More high-quality studies are needed to lend further validity to this supposition.

Beta-alanine (Carnosyn™) supplementation in elderly subjects (60-80 years): effects on muscle carnosine content and physical capacity

The aim of this study was to investigate the effects of beta-alanine supplementation on exercise capacity and the muscle carnosine content in elderly subjects. Eighteen healthy elderly subjects (60-80 years, 10 female and 4 male) were randomly assigned to receive either beta-alanine (BA, n=12) or placebo (PL, n=6) for 12 weeks. The BA group received 3.2 g of beta-alanine per day (2×800 mg sustained-release Carnosyn™ tablets, given 2 times per day). The PL group received 2× (2×800 mg) of a matched placebo. At baseline (PRE) and after 12 weeks (POST-12) of supplementation, assessments were made of the muscle carnosine content, anaerobic exercise capacity, muscle function, quality of life, physical activity and food intake. A significant increase in the muscle carnosine content of the gastrocnemius muscle was shown in the BA group (+85.4%) when compared with the PL group (+7.2%) (p=0.004; ES: 1.21). The time-to-exhaustion in the constant-load submaximal test (i.e., TLIM) was significantly improved (p=0.05; ES: 1.71) in the BA group (+36.5%) versus the PL group (+8.6%). Similarly, time-to-exhaustion in the incremental test was also significantly increased (p=0.04; ES 1.03) following beta-alanine supplementation (+12.2%) when compared with placebo (+0.1%). Significant positive correlations were also shown between the relative change in the muscle carnosine content and the relative change in the time-to-exhaustion in the TLIM test (r=0.62; p=0.01) and in the incremental test (r=0.48; p=0.02). In summary, the current data indicate for the first time, that beta-alanine supplementation is effective in increasing the muscle carnosine content in healthy elderly subjects, with subsequent improvement in their exercise capacity.

Exercise for bone health: rationale and prescription

PURPOSE OF REVIEW

Patients frequently inquire about exercise as a means to improve bone strength and reduce osteoporotic fracture. Understanding the biologic mechanisms and the available clinical evidence supporting the role of exercise in bone health is the key to an educated discussion.

RECENT FINDINGS

Exercise downregulates sclerostin expression by the osteocyte favoring osteoblastogenesis. These changes are enhanced by dynamic cyclical load with rest periods and may be promoted by low-amplitude high-frequency stimuli. In the prepubertal years, exercise results in periosteal gains, whereas exercise later in life maintains bone mass, reduces falls and probably associated fractures, and improves quality-of-life measures.

SUMMARY

Future studies should examine the effect of exercise on bone strength and determine the minimum quantity and frequency and the exercise type most effective to reduce osteoporotic fractures.
