Exercise for improving outcomes after osteoporotic vertebral fracture

Dynamic spinal orthoses self-reported effects in patients with back pain due to vertebral fragility fractures: A multi-center prospective cohort study

BACKGROUND

Vertebral fragility fractures (VFFs) commonly result from low bone mass and microarchitecture deterioration of bone tissue. spinal orthoses are common non-pharmacological options for managing vertebral fracture pain. However, the effects of spinal orthoses on pain, physical functioning, and quality of life (QoL) are still debated.

OBJECTIVE

This survey aimed to investigate the patients-reported outcomes of a dynamic spinal orthosis prescribed in the routine clinical practice of VFFs management.

METHODS

This multi-center national-wide prospective cohort study assessed older patients (aged > 60 years) diagnosed with acute VFFs and prescribed with a dynamic spinal orthosis (Spinfast®). A survey questionnaire was realized and included sections on patient characterization, osteoporosis characterization, spinal orthosis, clinical outcomes, pain medications, and osteoporosis medications. The questionnaire was administered at baseline and after three months. A total of 68 patients completed the questionnaire at three months. Most patients had one or two VFFs and were treated with pain medications and osteoporosis medications. Compliance and tolerability of the spinal orthosis were assessed, and clinical outcomes such as pain intensity, physical functioning, and QoL were measured.

RESULTS

The results showed no significant differences in outcomes between age subgroups. Italian physical medicine and rehabilitation physicians were commonly involved in the management of VFFs patients. Sixty-six patients completed the questionnaire. The results showed that pain intensity, physical functioning and QoL improved after three months of spinal orthosis wearing (p< 0.0001).

CONCLUSION

The correct management of VFFs is mandatory to improve pain and reduce disability, and our findings suggested a positive role of dynamic spinal orthosis to improve the comprehensive management of VFFs patients. However, high-quality research trials are warranted to provide clear recommendations for the correct clinical management of VFF.

[Osteoporotic vertebral body fractures]

The number of osteoporotic fractures of the spine is increasing. These fractures are associated with elevated morbidity and mortality. This article provides an overview of the special features of these fractures, the diagnostic procedure, their classification, and the conservative and surgical treatment options. For the mostly elderly patients, it is important to treat the underlying disease and to address associated problems such as frailty and sarcopenia. To meet this growing medical and socio-economic challenge, a holistic interdisciplinary and interprofessional treatment approach is required.

Survival following vertebral compression fractures in population over 65 years old

BACKGROUND

Lower mortality has been demonstrated when vertebral compression fractures (VCFs) are treated surgically (vertebral augmentation) vs. conservatively.

AIMS

To analyze the overall survival in patients over 65 who suffer a VCF, to review the principal causes of death, and to detect which factors are associated with a greater risk of mortality.

METHODS

Patients over 65 years old diagnosed with acute, non-pathologic thoracic or lumbar VCF, treated consecutively from January 2017 to December 2020, were retrospectively selected. Those patients with follow-ups under 2 years or who required arthrodesis were excluded. Overall survival was estimated by the Kaplan-Meier method. Differences in survival were tested through the log-rank test. Multivariable Cox regression was used to assess the association of covariates and time to death.

RESULTS

A total of 492 cases were included. Overall mortality was 36.2%. Survival rate at 1-, 12-, 24-, 48-, and 60-month follow-up was 97.4%, 86.6%, 78.0%, 64.4%, and 59.4%, respectively. Infection was the leading cause of death. The independent factors associated with a higher mortality risk were age, male, oncologic history, non-traumatic mechanism, and comorbidity during hospitalization. No statistical difference was found when comparing the two survival curves by treatment (vertebral augmentation vs. conservative) over time.

CONCLUSION

Overall mortality rate was 36.2% after a median follow-up of 50.5 months (95% CI 48.2; 54.2). Age, male sex, history of oncological disease, non-traumatic mechanism of the fracture, and any comorbidity during hospitalization were identified as variables independently associated with a higher risk of mortality following a VCF in the elderly.

Treatment and Outcome of Osteoporotic Thoracolumbar Vertebral Body Fractures With Deformation of Both Endplates With or Without Posterior Wall Involvement (OF 4): Short-Term Results from the Prospective EOFTT Multicenter Study

STUDY DESIGN

Multicenter prospective cohort study.

OBJECTIVE

To analyse therapeutical strategies applied to osteoporotic thoracolumbar OF 4 injuries, to assess related complications and clinical outcome.

METHODS

A multicenter prospective cohort study (EOFTT) including 518 consecutive patients who were treated for an Osteoporotic vertebral compression fracture (OVCF). For the present study, only patients with OF 4 fractures were analysed. Outcome parameters were complications, Visual Analogue Scale, Oswestry Disability Questionnaire, Timed Up & Go test, EQ-5D 5L, and Barthel Index after a minimum follow-up of 6 weeks.

RESULTS

A total of 152 (29%) patients presented with OF 4 fractures with a mean age of 76 years (range 41-97). The most common treatment was short-segment posterior stabilization (51%; hybrid stabilization in 36%). Mean follow up was 208 days (±131 days), mean ODI was 30 ± 21. Dorsoventral stabilized patients were younger compared to the other groups (P < .001) and had significant better TuG compared to hybrid stabilization (P = .049). The other clinical outcomes did not differ in the therapy strategies (VAS pain: P = 1.000, ODI: P > .602, Barthel: P > .252, EQ-5D 5L index value: P > .610, VAS-EQ-5D 5L: P = 1.000). The inpatient complication rate was 8% after conservative and 16% after surgical treatment. During follow-up period 14% of conservatively treated patients and 3% of surgical treated patients experienced neurological deficits.

CONCLUSIONS

Conservative therapy of OF 4 injuries seems to be viable option in patients with only moderate symptoms. Hybrid stabilization was the dominant treatment strategy leading to promising clinical short-term results. Stand-alone cement augmentation seems to be a valid alternative in selected cases.

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

Purpose

This study aimed to use meta-analysis to determine the impact of resistance and balance training on athletic ability and quality of life for patients with osteoporotic vertebral fracture (OVF).

Methods

This study followed the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) criteria for systematic reviews and meta-analyzes. The PubMed, Web of science, Cochrane, Embase, and CNKI databases were searched for randomized controlled trials (RCTs) up to September 2022. The search strategy was related to the intervention measures, population, and results, and was structured around the search terms: “Exercise,” “Osteoporotic vertebral fracture,” and “activities of function.” Two reviewers strictly implemented the inclusion and exclusion criteria. Subgroup analyzes of age and training duration were performed for the main outcomes.

Results

We included 12 RCTs (n = 1,289) of resistance and balance training in patients with OVF. Compared with controls, the intervention group showed improvements on the Quality of Life Questionnaire issued by the European Foundation for Osteoporosis, visual analog pain scale, Timed Up and Go, falls efficacy scale international (FES-I), kyphosis, and functional reach. On subgroup analysis, the effect was more significant when training continued &gt;10 weeks.

Conclusion

Resistance and balance exercise training improved function and balance, and reduced fall risk in patients with OVF. We recommend resistance and balance training for at least 10 weeks. Future multicenter, large sample trials are needed for more reliable conclusions.

International consensus on the non-pharmacological and non-surgical management of osteoporotic vertebral fractures

We identified a knowledge gap in the non-pharmacological and non-surgical management of osteoporotic vertebral fractures.

MAIN RESULTS

This international consensus process established multidisciplinary biopsychosocial recommendations on pain, nutrition, safe movement, and exercise for individuals with acute and chronic vertebral fractures.

SIGNIFICANCE

These recommendations will guide clinical practice and inform interventions for future research.

PURPOSE

To establish international consensus on recommendations for the non-pharmacological and non-surgical management of osteoporotic vertebral fractures.

METHODS

We adopted a five-step modified Delphi consensus process: (1) literature search and content analysis, (2) creation of the survey, (3) selection of the expert panel, (4) first round of the rating process, and (5) second round of the rating process. The first round included 49 statements and eight open-ended questions; the second round included 30 statements. Panelists were asked to rate their agreement with each of the statements using a 9-point scale, with the option to provide further comments. Consensus for each statement was determined by counting the number of panelists whose rating was outside the 3-point region containing the median.

RESULTS

We invited 76 people with degree in medicine, physiotherapy, kinesiology, and experience in the management of osteoporotic vertebral; 31 (41%) and 27 (36%) experts agreed to participate to the first and the second round, respectively. The mean percentage agreement after the first and second rounds was 76.6% ± 16.0% and 90.7% ± 6.5%, respectively. We established consensus on recommendations on pain, early satiety, weight loss, bracing, safe movement, and exercise for individuals with acute and chronic vertebral fractures.

CONCLUSION

Our international consensus provides multidisciplinary biopsychosocial recommendations to guide the management of osteoporotic vertebral fractures and inform interventions for future research.

Background

The field of rehabilitation medicine plays an essential role in the comprehensive management of osteoporosis and its consequences. The benefits of therapeutic exercise are increasingly being recognized in this area, which receives an increasing number of publications. this study was designed to comprehensively identify collaborative networks, parse and track research trends, spotlight present hotspots, and accurately predict frontiers and focus on the health topics related to osteoporosis rehabilitation.

Methods

This research adopted computer retrieval of osteoporosis rehabilitation-related research published in the Web of Science Core Collection (WoSCC) from inception to June 14, 2022. The bibliometric visualization and comparative analysis involving countries, institutions, journals, authors, references, and keywords were performed using the CiteSpace and VOSviewer software.

Results

A total of 3,268 articles were included, and the number of articles published each year has demonstrated a steady increase. The United States and the University of Melbourne were the highest productive country and institution, with 1,325 and 87 articles, respectively. The journal of osteoporosis international has published the greatest number of articles, with 221 publications, and the journal of bone and mineral research ranked first in the co-citation counts (cited by 11,792 times). The most productive and highly-cited authors were Heinonen A and Cummings S, with 35 publications and 680 citations.

Conclusions

At present, "physical activity," "weight bearing exercise," "muscle strength," "whole body vibration," "postmenopausal women," "older women," children, men are the noteworthy research hot topics. Future research that focus on the major modes and parameters of physical activity/exercise for osteoporosis (including whole body vibration, weight bearing exercises, resistance training), targeted multicomponent training regimens, rehabilitation therapy for postmenopausal women, older women, children and men, osteoporosis related-sarcopenia and fractures, and mesenchymal stem cells are becoming frontiers and focus on the health topics related to osteoporosis rehabilitation in the upcoming years, which are worthy of further exploration.

Commentary: Zebrafish as a Model for Osteoporosis-An Approach to Accelerating Progress in Drug and Exercise-Based Treatment

Osteoporosis (OP) is a degenerative disease characterized by reduced bone strength and increased fracture risk. As the global population continues to age, the prevalence and economic burden of osteoporosis can be expected to rise substantially, but there remain various gaps in the field of OP care. For instance, there is a lack of anti-fracture drugs with proven long-term efficacy. Likewise, though exercise remains widely recommended in OP prevention and management, data regarding the safety and efficacy for patients after vertebral fracture remain limited. This lack of evidence may be due to the cost and inherent difficulties associated with exercise-based OP research. Thus, the current research landscape highlights the need for novel research strategies that accelerate OP drug discovery and allow for the low-cost study of exercise interventions. Here, we outline an example of one strategy, the use of zebrafish, which has emerged as a potential model for the discovery of anti-osteoporosis therapeutics and study of exercise interventions. The strengths, limitations, and potential applications of zebrafish in OP research will be outlined.

Observation of the clinical effectiveness of evidence-based nursing for patients with a vertebral osteoporotic fracture

BACKGROUND

An osteoporotic fracture (OPF) can significantly affect patients' activities of daily living (ADLs).

OBJECTIVE

This study observed the effects of evidence-based nursing (EBN) on the occurrence of postoperative complications and ADLs in patients with a vertebral OPF.

METHODS

A total of 90 patients with vertebral OPF were divided into two groups. The conventional orthopedic nursing method was conducted for the control group, and the EBN model was delivered for the observation group.

RESULTS

Differences in the Barthel index (BI) score on the first day of admission were not statistically significant between the two groups. The BI scores on the day before discharge, compared with the day of admission, had improved in both groups. The BI score on the day before discharge was 83.67 ± 6.94 in the observation group, and the difference was statistically significant (P< 0.05) compared with the control group (76.56 ± 6.89). The rate of satisfaction with nursing in the observation group (100.0%) was significantly higher than in the control group (82.2%) (P< 0.05). The incidence of postoperative complications in the observation group (2.2%) was significantly lower than in the control group (24.4%) (P< 0.05).

CONCLUSIONS

The implementation of EBN in patients with vertebral OPF improved the postoperative ADLs, reduced the incidence of postoperative complications, and improved the patients' satisfaction with nursing.

The Impact of an Adapted Physical Activity Program on Bone Turnover, Physical Performance and Fear of Falling in Osteoporotic Women with Vertebral Fractures: A Quasi-Experimental Pilot Study

Physical activity has been indicated as a potential strategy to counteract osteoporosis (OP). This study of post-menopausal women with osteoporotic vertebral fractures investigated the effect of an adapted physical activity (APA) program on two serum bone turnover biomarkers (Bone Alkaline Phosphatase, B-ALP and C-terminal telopeptide of type 1 collagen, CTX-1), functional capacity (6-Minutes Walking Test, 6MWT), and risk and fear of falls (Tinetti and Falls Efficacy scale). The APA group (n = 12) performed a 1-h group session twice per week for 6 months whereas the control group (n = 9) was asked to maintain their current lifestyle. The exercise program did not affect the serum concentrations of B-ALP and CTX-1 biomarkers measured at the baseline and after 6 months in women of the APA group. Moreover, at the end of intervention no significant differences in serum concentrations for either biomarker was observed between the two study groups. Interestingly, when compared to the control group, women in the APA group showed significant improvement in the functional capacity measures by 6MWT (p = 0.037) and a decrease of the risk and fear of falls as indicated by the Tinetti test (p = 0.043). Based on these findings, exercise could provide new perspectives for the care and management of OP.

Physiotherapy exercise rehabilitation with tailored exercise adherence support for people with osteoporosis and vertebral fractures: protocol for a randomised controlled trial - the OsteoPorosis Tailored exercise adherence INtervention (OPTIN) study

INTRODUCTION

Vertebral fragility fractures affect at least 20% of the older population in the UK. Best practice guidelines recommend the use of exercise to slow the rate of bone loss, to maintain muscle strength and physical function, and to prevent falls and further fractures. However, treatment effects are often small and difficult to sustain and adherence, or the extent to which patients engage in treatment, has been identified as an important issue by many studies. Our hypothesis is that integrating adherence intervention strategies with an exercise intervention will be beneficial. We will compare physiotherapy exercise rehabilitation with adherence support versus physiotherapy exercise rehabilitation alone in terms of effects on (A) physical function, quality of life and fear of falling and (B) exercise self-efficacy and adherence.

METHODS AND ANALYSIS

A multicentre, two-arm, parallel group, superiority randomised controlled trial with blinded assessments at baseline (0) and 4, 8 and 12 months, with a nested qualitative study and health economic analysis. 116 participants will be allocated to either (1) outpatient physiotherapy which will include a musculoskeletal assessment and treatment including balance, posture, strength training and low impact weight-bearing exercises over 16 weeks or (2) OsteoPorosis Tailored exercise adherence INtervention intervention. This includes standard physiotherapy as above plus an additional, integrated assessment interview (30 min) and 60 min of adherence support spread over the subsequent 16 weeks.

ETHICS AND DISSEMINATION

The study protocol was approved by West of Scotland Research Ethics Committee 4 (21/WS/0071). Trial registration number ISRCTN 14465704. The paper is based on Protocol V.4.

TRIAL REGISTRATION NUMBER

SPINE20 recommendations 2021: spine care for people's health and prosperity

PURPOSE

The focus of SPINE20 is to develop evidence-based policy recommendations for the G20 countries to work with governments to reduce the burden of spine disease, and disability.

METHODS

On September 17-18, 2021, SPINE20 held its annual meeting in Rome, Italy. Prior to the meeting, the SPINE20 created six proposed recommendations. These recommendations were uploaded to the SPINE20 website 10 days before the meeting and opened to the public for comments. The recommendations were discussed at the meeting allowing the participants to object and provide comments.

RESULTS

In total, 27 societies endorsed the following recommendations. SPINE20 calls upon the G20 countries: (1) to expand telehealth for the access to spine care, especially in light of the current situation with COVID-19. (2) To adopt value-based interprofessional spine care as an approach to improve patient outcomes and reduce disability. (3) To facilitate access and invest in the development of a competent rehabilitation workforce to reduce the burden of disability related to spine disorders. (4) To adopt a strategy to promote daily physical activity and exercises among the elderly population to maintain an active and independent life with a healthy spine, particularly after COVID-19 pandemic. (5) To engage in capacity building with emerging countries and underserved communities for the benefit of spine patients. (6) To promote strategies to transfer evidence-based advances into patient benefit through effective implementation processes.

CONCLUSIONS

SPINE20's initiatives will make governments and decision makers aware of efforts to reduce needless suffering from disabling spine pain through education that can be instituted across the globe.

UK clinical guideline for the prevention and treatment of osteoporosis

The National Osteoporosis Guideline Group (NOGG) has revised the UK guideline for the assessment and management of osteoporosis and the prevention of fragility fractures in postmenopausal women, and men age 50 years and older. Accredited by NICE, this guideline is relevant for all healthcare professionals involved in osteoporosis management.

INTRODUCTION

The UK National Osteoporosis Guideline Group (NOGG) first produced a guideline on the prevention and treatment of osteoporosis in 2008, with updates in 2013 and 2017. This paper presents a major update of the guideline, the scope of which is to review the assessment and management of osteoporosis and the prevention of fragility fractures in postmenopausal women, and men age 50 years and older.

METHODS

Where available, systematic reviews, meta-analyses and randomised controlled trials were used to provide the evidence base. Conclusions and recommendations were systematically graded according to the strength of the available evidence.

RESULTS

Review of the evidence and recommendations are provided for the diagnosis of osteoporosis, fracture-risk assessment and intervention thresholds, management of vertebral fractures, non-pharmacological and pharmacological treatments, including duration and monitoring of anti-resorptive therapy, glucocorticoid-induced osteoporosis, and models of care for fracture prevention. Recommendations are made for training; service leads and commissioners of healthcare; and for review criteria for audit and quality improvement.

CONCLUSION

The guideline, which has received accreditation from the National Institute of Health and Care Excellence (NICE), provides a comprehensive overview of the assessment and management of osteoporosis for all healthcare professionals involved in its management. This position paper has been endorsed by the International Osteoporosis Foundation and by the European Society for the Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases.

The global approach to rehabilitation following an osteoporotic fragility fracture: A review of the rehabilitation working group of the International Osteoporosis Foundation (IOF) committee of scientific advisors

PURPOSE

To conduct a review of the current state of the evidence for rehabilitation strategies post-fragility fracture.

METHODS

Narrative review conducted by the Rehabilitation Working Group of the International Osteoporosis Foundation Committee of Scientific Advisors characterizing the range of rehabilitation modalities instrumental for the management of fragility fractures.

RESULTS

Multi-modal exercise post-fragility fracture to the spine and hip is strongly recommended to reduce pain, improve physical function, and improve quality of life. Outpatient physiotherapy post-hip fracture has a stronger evidence base than outpatient physiotherapy post-vertebral fracture. Appropriate nutritional care after fragility fracture provides a large range of improvement in morbidity and mortality. Education increases understanding of osteoporosis which in turn increases utilization of other rehabilitation services. Education may improve other health outcomes such as pain and increase a patient's ability for self-advocacy.

CONCLUSION

Rehabilitation interventions are inter-reliant, and research investigating the interaction of exercise, nutrition, and other multi-modal therapies may increase the relevance of rehabilitation research to clinical care.

Application of Machine Learning in Developing Decision-Making Support Models for Decompressed Vertebroplasty

BACKGROUND

The common treatment methods for vertebral compression fractures with osteoporosis are vertebroplasty and kyphoplasty, and the result of the operation may be related to the value of various measurement data during the operation.

MATERIAL AND METHOD

This study mainly uses machine learning algorithms, including Bayesian networks, neural networks, and discriminant analysis, to predict the effects of different decompression vertebroplasty methods on preoperative symptoms and changes in vital signs and oxygen saturation in intraoperative measurement data.

RESULT

The neural network shows better analysis results, and the area under the curve is >0.7. In general, important determinants of surgery include numbness and immobility of the lower limbs before surgery.

CONCLUSION

In the future, this association model can be used to assist in decision making regarding surgical methods. The results show that different surgical methods are related to abnormal vital signs and may affect the length of hospital stay.

The "Three in One" Bone Repair Strategy for Osteoporotic Fractures

In aging society, osteoporotic fractures have become one major social problem threatening the health of the elderly population in China. Compared with conventional fractures, low bone mass, bone defect and retarded healing issues of osteoporotic fractures lead to great difficulties in treatment and rehabilitation. Addressing major concerns in clinical settings, we proposed the "three in one" bone repair strategy focusing on anti-osteoporosis therapies, appropriate bone grafting and fracture healing accelerating. We summarize misconceptions and repair strategies for osteoporotic fracture management, expecting improvement of prognosis and clinical outcomes for osteoporotic fractures, to further improve therapeutic effect and living quality of patients.

Osteoporotic Fractures of the Thoracic and Lumbar Vertebrae: Diagnosis and Conservative Treatment

BACKGROUND

The prevalence of osteoporotic vertebral body fractures in Europe is 18-26%. Although most of these injuries can be treated conservatively, the underlying concepts have not been defined clearly or uniformly. In this article, we present the current state of the evidence on the diagnosis and conservative treatment of osteoporotic fractures of the thoracic and lumbar vertebrae.

METHODS

A systematic review of the literature up to May 2020 was carried out in the PubMed and Web of Science Core Collection databases. 549 articles were identified, of which 36 were suitable for inclusion in the review. Articles were sought in the areas of diagnosis, provision of physical aids, pharmacotherapy, physiotherapy, and treatments from the realm of alternative medicine.

RESULTS

The primary diagnostic technique was conventional x-ray in two planes (with the patient standing, if possible), which had 51.3% sensitivity and 75% specificity. If a fracture was suspected, magnetic resonance imaging (MRI) of the entire spine and regional computed tomography (CT) were carried out. The overall state of the evidence on treatment is poor; the best available evidence is for exercise therapy and physiotherapy, which are supported by three level I and four level II studies. Improvements were seen mainly in mobility and a reduced fear of falling. The use of an active orthosis can be useful as well. No evidence was found on the use of drugs or alternative medicine exclusively in the conservative treatment of osteoporotic vertebral body fractures.

CONCLUSION

It is reasonable to evaluate instability with imaging repeatedly, at regular intervals, over a period of six months. There is still a lack of reliable data on the optimal intensity and duration of physiotherapy, and on the use of orthoses.

Exercise for improving age-related hyperkyphosis: a systematic review and meta-analysis with GRADE assessment

We reviewed exercise trials in men and women ≥ 45 years with hyperkyphosis at the baseline and performed meta-analyses for kyphosis and health-related outcomes.

PURPOSE

To determine the effects of exercise interventions on kyphosis angle, back extensor muscle strength or endurance, physical functioning, quality of life, pain, falls, and adverse events in adults 45 years or older with hyperkyphosis.

METHODS

Multiple databases were searched to May 2020. Randomized controlled trials (RCTs), non-RCT, and pre-post intervention studies that had at least one group with a mean kyphosis angle of at least 40° at the baseline were included.

RESULTS

Twenty-four studies were included. Exercise or physical therapy improved kyphosis outcomes (SMD - 0.31; 95% confidence intervals [CI] - 0.46, - 0.16; moderate certainty evidence), back extensor muscle strength (MD 10.51 N; 95% CI 6.65, 14.38; very low certainty evidence), and endurance (MD 9.76 s; 95% CI 6.40, 13.13; low certainty evidence). Meta-analyses showed improvements in health-related quality of life (HRQoL) (SMD 0.21; 95% CI 0.06, 0.37; moderate certainty of evidence), general pain (MD - 0.26; 95% CI - 0.39, - 0.13; low certainty of evidence), and performance on the timed up and go (TUG) test (MD - 0.28 s; 95% CI - 0.48, - 0.08; very low certainty of evidence). The effects on the rate of falls (incidence rate ratio [IRR] 1.15; 95% CI 0.64, 2.05; low certainty evidence) or minor adverse events (IRR 1.29; 95% CI 0.95, 1.74; low certainty evidence) are uncertain. No serious adverse events were reported in the included studies.

CONCLUSIONS

Interventions targeting hyperkyphosis may improve kyphosis outcomes in adults with hyperkyphosis.

Impact of Rehabilitation Intensity on 3-Year Mortality among Children with Moderate to Severe Cerebral Palsy: A Population-Based Cohort Study

Though numerous studies demonstrated the positive effect of rehabilitation on cerebral palsy (CP) children, there was no literature addressing the role of rehabilitation on mortality among children with CP. Therefore, we aimed to evaluate the impact of rehabilitation intensity on mortality among children with moderate to severe CP. This retrospective cohort study was conducted by National Health Insurance Research Database in Taiwan. Children (<12 years) with newly diagnosed moderate to severe CP between 1 January 2000 and 31 December 2013 were included. All patients were followed up for 3 years after CP diagnosis or death or until 31 December 2013. The intensity of rehabilitation therapy within 6 months after CP diagnosis was categorized into <6 times and ≥6 times. The Cox proportional hazard analysis was used to determine the association between rehabilitation intensity and all-cause mortality after adjusting age, sex, other demographic factors and comorbidities. Among 3936 severe CP children, 164 (4.2%) died during the 3-year follow-up period. The mortality rate was higher among patients receiving rehabilitation < 6 times within 6 months than those ≥6 times within 6 months after adjusting demographic profile and comorbidities (adjust HR (aHR): 1.96, 95% CI 1.33–2.89, p < 0.001). We found that patients who were younger (aHR: 0.84, 95% CI 0.76–0.92, p < 0.001), who were receiving inpatient care more than twice in 1 year before their CP diagnosis (aHR: 2.88; 95% CI: 1.96–4.23; p < 0.001), and who have pneumonia (aHR: 1.41, 95% CI 1.00–1.96, p = 0.047), epilepsy (aHR: 1.41, 95% CI: 1.02–1.95, p = 0.039) and dysphagia (aHR: 1.55, 95% CI: 1.06–2.26, p = 0.024) have higher risk of mortality. Rehabilitation ≥ 6 times within 6 months has a potentially positive impact on pediatric CP survival. Besides having a younger age, being hospitalized more than twice within a year before diagnosis and having pneumonia, epilepsy and dysphagia were modifiable risk factors in clinical practice for these children.

Biophysical Modulation of the Mitochondrial Metabolism and Redox in Bone Homeostasis and Osteoporosis: How Biophysics Converts into Bioenergetics

Bone-forming cells build mineralized microstructure and couple with bone-resorbing cells, harmonizing bone mineral acquisition, and remodeling to maintain bone mass homeostasis. Mitochondrial glycolysis and oxidative phosphorylation pathways together with ROS generation meet the energy requirement for bone-forming cell growth and differentiation, respectively. Moderate mechanical stimulations, such as weight loading, physical activity, ultrasound, vibration, and electromagnetic field stimulation, etc., are advantageous to bone-forming cell activity, promoting bone anabolism to compromise osteoporosis development. A plethora of molecules, including ion channels, integrins, focal adhesion kinases, and myokines, are mechanosensitive and transduce mechanical stimuli into intercellular signaling, regulating growth, mineralized extracellular matrix biosynthesis, and resorption. Mechanical stimulation changes mitochondrial respiration, biogenesis, dynamics, calcium influx, and redox, whereas mechanical disuse induces mitochondrial dysfunction and oxidative stress, which aggravates bone-forming cell apoptosis, senescence, and dysfunction. The control of the mitochondrial biogenesis activator PGC-1α by NAD+-dependent deacetylase sirtuins or myokine FNDC/irisin or repression of oxidative stress by mitochondrial antioxidant Nrf2 modulates the biophysical stimulation for the promotion of bone integrity. This review sheds light onto the roles of mechanosensitive signaling, mitochondrial dynamics, and antioxidants in mediating the anabolic effects of biophysical stimulation to bone tissue and highlights the remedial potential of mitochondrial biogenesis regulators for osteoporosis.

Spinal Orthoses Prescription for Vertebral Fragility Fractures by Italian Physical and Rehabilitation Medicine Physicians: The SPIN-VER Survey

Vertebral fragility fractures (VFFs) are the most common type of osteoporotic fractures, related to pain and disability. In this scenario, physical and rehabilitative medicine (PRM) physicians prescribe a patient-tailored rehabilitation plan, including spinal orthoses. However, there is a high heterogeneity in the clinical indications of spinal orthoses. Thus, the aim of this survey was to investigate common clinical practice in terms of the prescription of spinal orthoses. This nationwide cross-sectional survey recruited Italian PRM physicians commonly involved in the management of patients with VFFs. One hundred twenty-six PRM physicians completed the survey. The results showed that most PRM physicians prescribe spinal orthoses in outpatients suffering from VFFs (n = 106; 83.9%). The most prescribed spinal orthosis for acute VFF patients was the three-point rigid orthosis (n = 64; 50.8%), followed by the semirigid thoraco-lumbar orthosis (n: 20; 15.9%). However, most PRM physicians prescribed dynamic orthoses in outpatients with chronic VFFs (n = 66; 52.4%). Albeit that a correct management of VFFs is mandatory to improve pain and reduce disability, our findings highlighted uncertainty in the type of spinal orthosis prescription in both the acute and chronic VFF phase. Therefore, high-quality research trials are warranted to provide clear recommendations for the correct clinical management of VFF.

Comparison of different predicting models to assist the diagnosis of spinal lesions

In neurosurgical or orthopedic clinics, the differential diagnosis of lower back pain is often time-consuming and costly. This is especially true when there are several candidate diagnoses with similar symptoms that might confuse clinic physicians. Therefore, methods for the efficient differential diagnosis can help physicians to implement the most appropriate treatment and achieve the goal of pain reduction for their patients.In this study, we applied data-mining techniques from artificial intelligence technologies, in order to implement a computer-aided auxiliary differential diagnosis for a herniated intervertebral disc, spondylolithesis, and spinal stenosis. We collected questionnaires from 361 patients and analyzed the resulting data by using a linear discriminant analysis, clustering, and artificial neural network techniques to construct a related classification model and to compare the accuracy and implementation efficiency of the different methods.Our results indicate that a linear discriminant analysis has obvious advantages for classification and diagnosis, in terms of accuracy.We concluded that the judgment results from artificial intelligence can be used as a reference for medical personnel in their clinical diagnoses. Our method is expected to facilitate the early detection of symptoms and early treatment, so as to reduce the social resource costs and the huge burden of medical expenses, and to increase the quality of medical care.

SPINE20 A global advocacy group promoting evidence-based spine care of value

PURPOSE

The Global Burden of Diseases (GBD) Studies have estimated that low back pain is one of the costliest ailments worldwide. Subsequent to GBD publications, leadership of the four largest global spine societies agreed to form SPINE20. This article introduces the concept of SPINE20, the recommendations, and the future of this global advocacy group linked to G20 annual summits.

METHODS

The founders of SPINE20 advocacy group coordinated with G20 Saudi Arabia to conduct the SPINE20 summit in 2020. The summit was intended to promote evidence-based recommendations to use the most reliable information from high-level research. Eight areas of importance to mitigate spine disorders were identified through a voting process of the participating societies. Twelve recommendations were discussed and vetted.

RESULTS

The areas of immediate concern were "Aging spine," "Future of spine care," "Spinal cord injuries," "Children and adolescent spine," "Spine-related disability," "Spine Educational Standards," "Patient safety," and "Burden on economy." Twelve recommendations were created and endorsed by 31/33 spine societies and 2 journals globally during a vetted process through the SPINE20.org website and during the virtual inaugural meeting November 10-11, 2020 held from the G20 platform.

CONCLUSIONS

This is the first time that international spine societies have joined to support actions to mitigate the burden of spine disorders across the globe. SPINE20 seeks to change awareness and treatment of spine pain by supporting local projects that implement value-based practices with healthcare policies that are culturally sensitive based on scientific evidence.

Long-term participation in community group exercise improves lower extremity muscle strength and delays age-related declines in walking speed and physical function in older adults

BACKGROUND

The effects of group exercise on the physical function of community-dwelling older adults remain unclear. The changes in lower extremity muscle strength, timed up and go (TUG) time, and the motor fitness scale (MFS), over time, among older adults who expressed a willingness to participate in community-based physical exercise groups, were determined using multilevel modelling.

METHODS

We analyzed data of 2407 older adults between April 2010 and December 2019 from the registry of physical tests of community-based physical exercise groups. We conducted a retrospective cohort study to assess the effect of physical exercise on lower extremity muscle strength, TUG time, and MFS scores. The durations of the exercises were evaluated by frequency of physical test's participate.

RESULTS

A deterioration in lower extremity muscle strength was found in the short-term participant group only. However, in the mid-term and long-term participation groups, lower extremity muscle strength showed a trend of improvement. The TUG time and the MFS score were negatively correlated with increasing age in both groups divided by the duration of participation. However, there was a slower rate of deterioration in the long-term participation group.

DISCUSSION

Lower extremity muscle strength, TUG time, and MFS scores decline with increasing age and there were differences in the slope of deterioration that depended on the duration of participation in community-based group exercise.

CONCLUSION

Participation in group exercise improved lower extremity muscle strength, TUG time, and MFS scores of older adults living in a community. The positive effects of group exercise were dependent on long-term participation.

The Effect of Impact Exercise (Alone or Multicomponent Intervention) on Health-Related Outcomes in Individuals at Risk of Fractures: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND

Exercise is commonly recommended to prevent and manage osteoporosis. High magnitude strains at rapid rate and short bouts should theoretically elicit an osteogenic response; however, the effects of different levels of impact exercises on several outcomes in people at risk of fracture are still unknown.

OBJECTIVE

To report the effect of impact exercise on falls, fractures, adverse events, mortality, bone mineral density (BMD), physical functioning, and health-related quality of life (QoL).

METHODS

We included randomized controlled trials testing the effect of impact exercise compared with a non-exercise control on outcomes in adults ≥ 50 years with low BMD or fragility fractures. Two reviewers selected studies and extracted data. Where possible, we pooled outcomes using mean difference (MD) with a fixed-effects model and 95% confidence interval (CI). We reported risk of bias using Cochrane and certainty of evidence using GRADE.

RESULTS

We included 29 trials; 19 studies evaluated impact exercise alone, and the remaining trials combined impact with resistance or balance training. Impact exercise alone or combined with resistance training improved Timed Up-and-Go values (MD - 0.95 s, 95% CI - 1.09 to - 0.81, low certainty evidence) and lumbar spine (MD 0.04 g/cm², 95% CI 0.02-0.06, low certainty evidence) and femoral neck BMD (MD 0.04 g/cm², 95% CI 0.02-0.07, low certainty evidence). Impact exercise did not improve health-related QoL assessed with QUALEFFO-41 (MD 0.06, 95% CI - 2.18 to 2.30, moderate certainty evidence). The effects of impact exercise on falls, fractures, and mortality are uncertain due to insufficient data. Many trials had a high risk of bias for two or more items.

CONCLUSIONS

There is low certainty evidence that impact exercise may improve physical function and BMD in people at risk of fracture. The effect of impact exercises on falls, fractures, and mortality remains unclear. Our findings should be interpreted with caution due to risk of bias and small sample sizes.

Effectiveness of Rehabilitative Intervention on Pain, Postural Balance, and Quality of Life in Women with Multiple Vertebral Fragility Fractures: A Prospective Cohort Study

Patients with vertebral fragility fractures often experience chronic pain, postural and balance disorders, and poor quality of life (QoL). Although several studies have investigated the role of rehabilitation in severe osteoporosis, the effectiveness of this intervention in patients with multiple vertebral fractures is poorly known. The aim of our longitudinal cohort study is to evaluate the effectiveness of rehabilitation, including postural training, resistance exercises, and visual stabilization exercises, for a 7-week period, on the pain, postural balance, and QoL of subjects with at least two vertebral fragility fractures receiving denosumab and vitamin D. We investigated, before (T0) and after (T1, at 7 weeks) rehabilitation, the following outcome measures on 28 patients: pain (Numerical Rating Scale (NRS)), self-perceived QoL (36-Item Short Form Survey (SF-36) and Mini-Osteoporosis Quality of Life Questionnaire (Mini-OQOL)), dizziness (Dizziness Handicap Inventory (DHI-I)), mobility (Timed-Up and Go (TUG) test), and instrumental posturographic assessment (FreeMed posturography system). At the end of the treatment, improvements of pain and QoL were recorded. Pain relief was highly obtained in patients with more than two vertebral fractures. Moreover, a significant functional improvement (TUG test) was found in those with two vertebral fractures, without any statistically significant change reported for other outcomes. Our findings suggest that combined intervention, including anti-osteoporotic drugs and postural rehabilitation, should be proposed to osteoporotic patients with multiple vertebral fractures.

Exploring thoracic kyphosis and incident fracture from vertebral morphology with high-intensity exercise in middle-aged and older men with osteopenia and osteoporosis: a secondary analysis of the LIFTMOR-M trial

Our aim was to explore change in kyphosis and vertebral fracture incidence following 8 months of high-intensity resistance and impact training (HiRIT) or machine-based isometric axial compression (IAC) training in men with osteopenia and osteoporosis. HiRIT and IAC improved posture. HiRIT participants did not experience progression or incident vertebral fracture. IAC participants did experience progression and incident vertebral fracture.

INTRODUCTION

The Lifting Intervention For Training Muscle and Osteoporosis Rehabilitation for Men (LIFTMOR-M) trial examined efficacy and safety of an eight-month, supervised, high-intensity progressive resistance and impact training (HiRIT) program compared with machine-based isometric axial compression (IAC) training in middle-aged and older men with low areal bone mineral density (aBMD). The primary purpose of the current work was to explore change in thoracic kyphosis and incident fracture from vertebral morphology following eight-months of HiRIT or IAC training. The secondary purpose was to explore change in clinical kyphosis measures for HiRIT, IAC and a non-randomized, matched control group.

METHODS

Men (≥ 45 yrs), with low aBMD, were recruited and randomized to HiRIT or IAC, or designated control. Clinical measures of thoracic kyphosis with inclinometry were determined. Cobb angle of kyphosis and vertebral fracture assessment using the Genant semi-quantitative method were determined from lateral thoracolumbar DXA (Medix DR, Medilink, France). Per-protocol (n = 40) and intention-to-treat (n = 93) analyses were conducted.

RESULTS

Forty participants (HiRIT n = 20, IAC n = 20; 66.1 ± 7.8 yrs.; lumbar spine T-score - 0.1 ± 0.8; femoral neck T-score - 1.5 ± 0.5) underwent clinical kyphosis measures and thoracolumbar DXA at baseline and follow-up. No between-group differences were detected in kyphosis change, however, within-group improvements in neutral (HiRIT - 2.3 ± 0.8°; IAC - 2.5 ± 0.8°) and 'standing tall' (HiRIT - 2.4 ± 0.8°; IAC - 2.0 ± 0.8°) postures were observed (p < 0.05). HiRIT improved Cobb angle (- 3.5 ± 1.5°, p = 0.027) from baseline. Over the 8 months, no incident vertebral fractures nor progression of prevalent vertebral fractures occurred for HiRIT participants. Five incident fractures of thoracic vertebrae occurred for IAC and one wedge fracture progressed. Ninety-three participants underwent clinical kyphosis measures at both time-points (HiRIT n = 34, IAC n = 33, control n = 26). HiRIT exhibited a reduction in 'standing tall' kyphosis compared to control (- 2.3 ± 0.6° versus 1.4 ± 0.7°, p < 0.05), but no other between-group differences were detected.

CONCLUSIONS

Although there was no difference in change between intervention groups, thoracic kyphosis appeared to improve in both HiRIT and IAC with exercise exposure. HiRIT improved 'standing tall' posture in comparison to usual activities. HiRIT was not associated with vertebral fracture progression or incident vertebral fracture, but for some IAC participants there was evidence of progression of vertebral fracture severity and incident vertebral fractures, in our small sample. Larger trials are required to confirm the observations of the current work, which was exploratory in nature.

Physical fitness in older women with osteoporosis and vertebral fracture after a resistance and balance exercise programme: 3-month post-intervention follow-up of a randomised controlled trial

Background

Exercise is recommended for individuals with vertebral fractures, but few studies have investigated the effect of exercise on outcomes of importance for this population. Post-intervention effects of exercise are even less studied. The objective of this study was to evaluate habitual walking speed and other health-related outcomes after cessation of a 3-month exercise intervention.

Methods

This follow-up study was conducted 3 months post-intervention of a randomised controlled trial. A total of 149 community-dwelling Norwegian women aged 65 years or older, diagnosed with osteoporosis and vertebral fracture were randomised into either exercise or control group. Primary outcome was habitual walking speed at 3 months. Secondary outcomes were other measures of physical fitness – including the Four Square Step Test (FSST), functional reach, grip strength and Senior Fitness Test – measures of health-related quality of life and fear of falling. Herein we report secondary data analysis of all outcomes at 6 months (3 months post-intervention). Data were analysed according to the intention-to-treat principle, linear mixed regression models were employed.

Results

For the primary outcome, habitual walking speed, there was no statistically significant difference between groups (0.03 m/s, 95%CI − 0.02 to 0.08, p = 0.271) at the 3-month post-intervention follow-up. For secondary outcomes of physical fitness, statistically significant differences in favour of the intervention group were found for balance using the FSST (− 0.68 s, 95%CI − 1.24 to − 0.11, p = 0.019), arm curl (1.3, 95%CI 0.25 to 2.29, p = 0.015), leg strength using the 30-s sit to stand (1.56, 95%CI 0.68 to 2.44, p = 0.001) and mobility using the 2.45-m up and go (− 0.38 s, 95%CI − 0.74 to − 0.02, p = 0.039). There was a statistically significant difference between the groups regarding fear of falling in favour of the intervention group (− 1.7, 95%CI − 2.97 to − 0.38, p = 0.011). No differences between groups were observed for health-related quality of life.

Conclusion

The results show the improved effects of a multicomponent exercise programme on outcomes like muscle strength, balance and mobility as well as fear of falling in a group of older women with osteoporosis and vertebral fracture 3 months post-intervention.

Effects of a resistance and balance exercise programme on physical fitness, health-related quality of life and fear of falling in older women with osteoporosis and vertebral fracture: a randomized controlled trial

Exercise is recommended for people with osteoporosis, but the effect for people who have suffered vertebral fracture is uncertain. This study shows that a multicomponent exercise-program based on recommendations for people with osteoporosis improved muscle strength, balance, and fear of falling in older women with osteoporosis and vertebral fracture.

INTRODUCTION

Guidelines for exercise strongly recommend that older adults with osteoporosis or osteoporotic vertebral fracture should engage in a multicomponent exercise programme that includes resistance training in combination with balance training. Prior research is scarce and shows inconsistent findings. This study examines whether current exercise guidelines for osteoporosis, when applied to individuals with vertebral fractures, can improve health outcomes.

METHODS

This single blinded randomized controlled trial included 149 older women diagnosed with osteoporosis and vertebral fracture, 65+ years. The intervention group performed a 12-week multicomponent exercise programme, the control group received usual care. Primary outcome was habitual walking speed, secondary outcomes were physical fitness (Senior Fitness Test, Functional Reach and Four Square Step Test), health-related quality of life and fear of falling. Descriptive data was reported as mean (standard deviation) and count (percent). Data were analyzed following intention to treat principle and per protocol. Between-group differences were assessed using linear regression models (ANCOVA analysis).

RESULTS

No statistically significant difference between the groups were found on the primary outcome, walking speed (mean difference 0.04 m/s, 95% CI - 0.01-0.09, p = 0.132). Statistically significant between-group differences in favour of intervention were found on FSST (dynamic balance) (mean difference - 0.80 s, 95% CI - 1.57 to - 0.02, p = 0.044), arm curl (mean difference 1.55, 95% CI 0.49-2.61, p = 0.005) and 30-s STS (mean difference 1.85, 95% CI 1.04-2.67, p < 0.001), as well as fear of falling (mean difference - 1.45, 95% CI - 2.64 to - 0.26, p = 0.018). No statistically significant differences between the groups were found on health-related quality of life.

CONCLUSION

Twelve weeks of a supervised multicomponent resistance and balance exercise programme improves muscle strength and balance and reduces fear of falling, in women with osteoporosis and a history of vertebral fractures.

The Effects of Home Exercise in Older Women With Vertebral Fractures: A Pilot Randomized Controlled Trial

BACKGROUND

Regular exercise is advocated in osteoporosis guidelines to prevent fractures. Few studies have evaluated the effect of exercise on functional performance, posture, and other outcomes that are important to patients after vertebral fractures.

OBJECTIVE

This pilot study will explore the effect of home exercise versus control on functional performance, posture, and patient-reported outcome measures.

DESIGN

This study was a parallel 2-arm pilot feasibility trial with 1:1 randomization to exercise or attentional control groups.

SETTING

This study took place in 5 Canadian and 2 Australian academic or community hospitals/centers.

PARTICIPANTS

This study included 141 women ≥65 years of age with radiographically confirmed vertebral fractures.

INTERVENTION

A physical therapist delivered exercise and behavioral counseling in 6 home visits over 8 months and monthly calls. Participants were to exercise ≥3 times weekly. Controls received equal attention.

MEASUREMENTS

Functional performance, posture, quality of life, pain, and behavior-change outcomes were assessed at baseline and after 6 (questionnaires only) and 12 months. Adherence to exercise was assessed by calendar diary. All t tests examined between-group mean differences (MD) in change from baseline in intention-to-treat and per-protocol analyses.

RESULTS

There was a small effect of exercise on 5 times sit-to-stand test versus control (MD = -1.58 [95% CI = -3.09 to -0.07], intention-to-treat; MD = -1.49 [95% CI = -3.12 to 0.16], per-protocol). There were no other major or statistically significant MDs for any other measured outcomes after follow-up. Adherence declined over time.

LIMITATIONS

Treatment effects on variables may have been underestimated due to multiple comparisons and underpowered analyses.

CONCLUSIONS

Our exploratory estimate of the effect of exercise on functional leg muscle strength was consistent in direction and magnitude with other trials in individuals with vertebral fractures. Declining adherence to home exercise suggests that strategies to enhance long-term adherence might be important in future confirmatory trials.

Management of hospitalised osteoporotic vertebral fractures

Management of hospitalised osteoporotic vertebral fracture patients was explored across all major trauma orthopaedic hospitals in Ireland. Findings, based on a survey of orthopaedic doctors and physiotherapists, indicate a lack of standardised clinical care pathways. This study will inform development of clinical audit mechanisms and health service development for this large and growing fracture population in both Ireland and internationally.

PURPOSE

To explore the management of hospitalised vertebral fragility fracture (VFF) patients in Ireland.

METHODS

A cross-sectional survey of orthopaedic doctors (specialist registrar level) and physiotherapists was conducted across all hospitals with major orthopaedic trauma units in Ireland. Data were analysed using descriptive statistics in SPSS (V24).

RESULTS

Responses were achieved from 100% (n = 16) of the hospitals (42 individual physiotherapists and 47 orthopaedic doctors). Conservative management was usual with both orthopaedic doctors (n = 37, 79%) and physiotherapists (n = 40, 96%) reporting prescription of bracing as common practice despite a lack of underpinning evidence. A majority (87%) of the doctors believed osteoporosis medications should commence prior to discharge from the acute setting, but 68% did not agree that responsibility for coordination and delivery of bone health assessment and fracture risk management rested with them. A majority (72%) of physiotherapists reported an absence or were unsure regarding existence of fracture liaison services. 73% of physiotherapists reported prescribing an inpatient or home (78%) exercise programme, including mobility, strength and balance exercise though detail on dose and adherence remain unknown. Wide variance in referral patterns to multi-disciplinary team (MDT) members existed although 79% of orthopaedic doctors supported an MDT approach.

CONCLUSION

Clinical care pathways for the hospitalised VFF population lack standardisation in Ireland. Key challenges reported by orthopaedic doctors and physiotherapists relate to pain management, osteoporosis medication prescription, clarity on indications for bracing and a lack of fracture liaison services. Clinical guidelines, defined clinical care pathways and high-quality clinical research trials are required for VFF management.

The Effect of Physical Activity on Bone Biomarkers in People With Osteoporosis: A Systematic Review

BACKGROUND

Bone imbalance between anabolic and catabolic processes at the level of remodeling unit due to the prevalence of resorbing activity, represents a health problem of aging. The consequence is the negative balance of bone turnover that can lead to osteoporosis. Physical activity (PA) can play a central role in the comprehensive management of osteoporosis, since it induces the anabolism of bone tissue. Bone turnover biomarkers, reflecting the cellular activity linked to bone metabolism, can represent an evaluation tool to assess the efficacy of PA in the osteoporotic population. The aim of this systematic review, conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, was to investigate the effects of PA interventions on bone biomarkers in people with osteoporosis.

METHODS

A comprehensive literature search of electronic databases was conducted through PubMed, Cochrane, Cinahl, Embase, Trip, to find randomized controlled trials (RCTs) investigating the topic of PA and bone turnover biomarkers in the osteoporosis population. In accordance with the Cochrane risk-of-bias tool, the quality of each study was assessed.

RESULTS

Out of 992 identified articles, 136 full texts were screened. Only three RTCs matched the eligibility criteria. In one study, sub-maximal aerobic exercise improved Bone-specific alkaline phosphatase (bone formation biomarker) and Amino-terminal Crosslinked Telopeptide of type 1 collagen (bone resorption biomarker) in osteoporotic women. The other two studies showed a positive effect on total alkaline phosphatase (a non-specific bone formation biomarker) in women with osteoporosis.

CONCLUSION

The systematic review revealed possible exercise benefits in terms of improving bone formation and decreasing bone resorption biomarkers in the osteoporotic population. However, these results should be interpreted with caution, especially due to the limited number and poor quality of the studies included. Further research is needed to estimate the influence of PA on bone biomarkers in the osteoporosis management.
