Effects of resistance and balance exercises for athletic ability and quality of life in people with osteoporotic vertebral fracture: Systematic review and meta-analysis of randomized control trials

Exercise for Postmenopausal Bone Health - Can We Raise the Bar?

PURPOSE OF REVIEW

This review summarises the latest evidence on effects of exercise on falls prevention, bone mineral density (BMD) and fragility fracture risk in postmenopausal women, explores hypotheses underpinning exercise-mediated effects on BMD and sheds light on innovative concepts to better understand and harness the skeletal benefits of exercise.

RECENT FINDINGS

Multimodal exercise programs incorporating challenging balance exercises can prevent falls. Emerging clinical trial evidence indicates supervised progressive high-intensity resistance and impact training (HiRIT) is efficacious in increasing lumbar spine BMD and is safe and well-tolerated in postmenopausal women with osteoporosis/osteopenia. There remains uncertainty regarding durability of this load-induced osteogenic response and safety in patients with recent fractures. Muscle-derived myokines and small circulating extracellular vesicles have emerged as potential sources of exercise-induced muscle-bone crosstalk but require validation in postmenopausal women. Exercise has the potential for multi-modal skeletal benefits with i) HiRIT to build bone, and ii) challenging balance exercises to prevent falls, and ultimately fractures. The therapeutic effect of such exercise in combination with osteoporosis pharmacotherapy should be considered in future trials.

Regular physical activity improves physical function and health-related quality of life among middle-aged and older women who suffered a fragility fracture-a population-based cohort

Fragility fractures are a major problem in our aging society leading to early death and loss of independence for activities of daily living. Physical activity in a long-term follow-up of Portuguese women over 50 years with a fragility fracture was associated with better physical function and quality of life.

PURPOSE

To evaluate the long-term impact of physical activity on physical function and health-related quality of life (HRQoL) in women ≥ 50 years old who suffered a fragility fracture.

METHODS

We evaluated the association of physical activity with physical function and HRQoL in women ≥ 50 years old who self-reported at least one low-impact fracture ≥ 40 years old from the EpiDoC cohort, a population-based cohort. Self-reported data regarding sociodemographics, clinical, and lifestyle behaviors were collected through a semi-structured questionnaire at baseline during a face-to-face clinical interview. During a long-term follow-up, a phone interview was conducted to evaluate physical activity (using a non-validated scale developed for the EpiDoC study), physical function (Health Assessment Questionnaire), and HRQoL (European Quality of Life - 5 Dimension). Women were divided into three groups according to the frequency of physical activity (non-frequent = 0 times/week, frequent = 1-2 times/week, or very frequent =  ≥ 3 times/week). The association of physical activity frequency (non-frequent, frequent, and very frequent) with physical function and HRQoL over time was assessed through linear mixed models considering varying intercepts for each woman.

RESULTS

This study followed 323 post-fracture women, during a mean follow-up of 3.9 ± 3.5 years. Frequent (β =  - 0.1419 [- 0.2783, - 0.0064]) and very frequent (β =  - 0.1908 [- 0.2944, - 0.0881]) physical exercise were associated with improvements in physical function relative to non-frequent physical exercise adjusted for BMI, multimorbidity, hospitalizations, alcohol and smoking habits, and the number of fragility fractures at baseline. As for HRQoL, a positive association was found for exercise frequency, specifically frequent (β = 0.1305 [0.0646, 0.1958]) and very frequent (β = 0.1354 [0.0856, 0.1859]) suggesting improvements for HRQoL, in this follow-up period.

CONCLUSIONS

These findings based on longitudinal data with long-term follow-up suggest that regular physical activity is associated with better function and HRQol among middle-aged and older post-fracture osteoporotic Portuguese women.

The effectiveness of virtual reality exercise games on balance functions and fear of falling in women with osteoporosis

To investigate and compare the effectiveness of Nintendo Wii games and home exercises on balance functions in patients with osteoporosis, an important disease adversely affecting balance functions. The patients included in the study were randomized into two groups the Wii exercise group (n = 30) and the home exercise group (n = 30). Wii exercise group performed balance exercises with a Nintendo Wii device and balance board three times a week for 12 weeks under the supervision of a physiotherapist in the hospital, and home exercise group was prescribed home exercises three days a week for 12 weeks. Balance functions were evaluated with the timed up-and-go-test and Berg Balance Scale, and the fall risk was evaluated with the Falls Efficacy Scale at the beginning and end of 12 weeks of treatment. Comparison of pre- and post-treatment timed up-and-go-test, Berg Balance Scale, and Falls Efficacy Scale results in both groups revealed statistically significant improvements (p = 0.001; p < 0.05). Furthermore, post-treatment test scores between the two groups demonstrated a significant enhancement in Wii exercise group regarding the Berg Balance Scale score (Mean ± SD 52.9 ± 3.63) (p = 0.001; p < 0.05). Within the osteoporotic population, balance functions serve as robust predictors of fall risk. Improvement in balance functions is crucial for the prevention of falls and subsequent osteoporotic fractures. In our study, we found that balance exercises performed with Wii games are effective in improving balance functions in patients with osteoporosis.

A Systematic Review of the Long-Term Effects of Using Smartphone- and Tablet-Based Rehabilitation Technology for Balance and Gait Training and Exercise Programs

Recent advances in wearable motion sensors, mobile devices, the Internet of Things, and telecommunications have created new potential for telerehabilitation. Recognizing that there is no systematic review of smartphone- or tablet-based balance and gait telerehabilitation technology for long-term use (i.e., four weeks or more), this systematic review summarizes the effects of smartphone- or tablet-based rehabilitation technology on balance and gait exercise and training in balance and gait disorders. The review examined studies written in English published from 2013 to 2023 in Web of Science, Pubmed, Scopus, and Google Scholar. Of the 806 studies identified, 14 were selected, and the National Institutes of Health Quality Assessment Tool for Observational Cohort and Cross-sectional Studies was applied to evaluate methodological quality. The systematic review concluded that all 14 studies found balance and gait performance improvement after four weeks or more of balance and gait telerehabilitation. Ten of the 14 studies found that carry-over effects (improved functional movements, muscle strength, motor capacity, cognition, and reduced fear of falling and anxiety levels) were maintained for weeks to months. The results of the systematic review have positive technical and clinical implications for the next-generation design of rehabilitation technology in balance and gait training and exercise programs.
