Which physical activity in patients affected by hypoparathyroidism? A review of the literature and practical recommendations

BACKGROUND

Hypoparathyroidism (HypoP) is a rare endocrine condition characterized by hypocalcaemia and hyperphosphatemia, as a consequence of absent or improperly low parathyroid hormone (PTH) levels. Patients affected by HypoP have a clinical condition often characterized by paresthesias and muscle spasms, as well as long-term consequences as nephrolithiasis, extraskeletal calcification, and fractures. In the literature, likely due to these symptoms, few data exist regarding the appropriate physical activity (PA) in subjects suffering from HypoP.

PURPOSE

This review evaluates the literature on exercise-based approaches to the management of individuals affected by HypoP and evaluates: (1) the effects of physical exercise on muscle cramps and other clinical symptoms; (2) the effects of exercise on PTH and calcium level; (3) the most suitable clinical exercise testing; and (4) the most suitable exercise combination.

METHODS AND RESULTS

A systematic search was conducted using the databases MEDLINE, Google Scholar using "hypoparathyroidism AND Physical Activity", "Training AND hypoparathyroidism", "Exercise AND muscle cramps", "Exercise AND Fatigue" as keywords. In addition, references list from the included articles were searched and cross-checked to identify any further potentially eligible studies. A total of 50 manuscripts were found among which 39 manuscripts were selected. A few clinical studies have been performed in HypoP patients to evaluate PA training protocols.

CONCLUSION

Although further research is needed to draw solid conclusions regarding best PA protocols in subjects affected by HypoP, a PA protocol has been proposed within the manuscript to encourage patients to attempt exercise to improve their clinical conditions and their quality of life.

A systematic review of Clinical Practice Guidelines for the management of fractures in children to develop the WHO's Package of Interventions for Rehabilitation

INTRODUCTION

Fractures have been identified as one of the 20 major health conditions for the World Health Organization's (WHO) Package of Interventions for Rehabilitation (PIR) - that includes also the needs of children and youth. The identification of existing interventions for rehabilitation and related evidence is a crucial step along the development of the PIR. The methods for the identification have been developed by WHO Rehabilitation Program and Cochrane Rehabilitation under the guidance of WHO's Guideline Review Committee Secretariat.

EVIDENCE ACQUISITION

This paper is part of the "Best Evidence for Rehabilitation" (be4rehab) series, developed according to the methodology presented in the PIR introductory paper. It is a systematic review of the existing Clinical Practice Guidelines (CPGs) on fractures in pediatric population published between 2009 to 2019.

EVIDENCE SYNTHESIS

We identified seven relevant CPGs after title and abstract screening. According to inclusion/exclusion criteria and after checking for quality, publication time, multidisciplinarity and comprehensiveness, we have been able to include two CPGs: one addresses the treatment of supracondylar humerus fractures and the other provides recommendations on the treatment of diaphyseal femur fractures.

CONCLUSIONS

The selected CPGs on the management of supracondylar humerus and diaphyseal femur fractures in pediatric population include few recommendations considered as interventions for rehabilitation, of low quality of evidence and weak strength. We found several gaps in specific rehabilitative topics. High quality studies are absolutely needed to upgrade the quality of available evidence to inform future development of guidelines.

Bone Alterations in Inflammatory Bowel Diseases: Role of Osteoprotegerin

Metabolic bone disorders are one of the most frequent extra-intestinal manifestations in patients with inflammatory bowel diseases (IBD) that might result in an increase of skeletal fragility and risk of fracture. These disorders are a consequence of bone−gut crosstalk alterations, particularly due to inflammation, which involves the RANK-RANKL-Osteoprotegerin (OPG) pathway. This cross-sectional study investigates the role of serum OPG on bone health in IBD patients. In all patients, we carried out BMD measurements at the lumbar spine and femoral neck by the dual-energy X-ray absorptiometry (DXA), and evaluation of serum OPG, 25(OH)D, and PTH. We also divided all IBD patients into two groups: group 1 consisted of premenopausal women and men younger than 50 years old, while group 2 included postmenopausal women and men aged more than 50 years old. We enrolled 36 UC patients (51%), 34 CD patients (49%), and 70 healthy controls. IBD group mean age was 44 ± 17.3 years old, with a mean disease duration of 6 years. IBD patients had a mean value of OPG of 48.1 ± 26.64 pg/mL, while mean OPG in the control group was 61.35 ± 47.19 pg/mL (p < 0.05). In group 1, there was a correlation between BMD Z-scores at the lumbar spine and femoral neck and mean OPG levels in UC subjects (r = 0.47 and r = −0.21, respectively; p < 0.05), and only between Z-score at the lumbar spine and OPG level in the CD group (r = 0.83, p < 0.05). For the patients of group 2, we report a statistically significant correlation between T-score measured at the lumbar site in both UC and CD patients (r = −0.79 and r = 0.77, respectively; p < 0.05). In our study, we demonstrated serum OPG levels to be significantly decreased in IBD subjects compared to healthy age-matched individuals. However, according to our data, it seems that the measurement of serum OPG levels is not useful to better define metabolic bone disorders in IBD patients.

Rehabilitative interventions for ischaemic digital ulcers, pain, and hand functioning in systemic sclerosis: a prospective before-after study

BACKGROUND

Systemic sclerosis (SSc) is a rare connective tissue disease characterised by immune dysfunction, vasculopathy, cellular inflammation, fibrosis of the skin associated with multiple internal organs involvement. Ischaemic digital ulcers (IDU) of the hands commonly occur in patients with SSc adversely affecting functional independence.

PURPOSE

Aim of the study is to investigate the effectiveness of a rehabilitation protocol based on the combined use of ultrasound (US) therapy and therapeutic exercise in terms of ulcers healing, pain relief, and hand functioning in patients affected by SSc with IDUs. Moreover, we also investigated the safety of the proposed intervention.

STUDY DESIGN

Prospective before-after study.

METHODS

We included 20 patients with IDUs secondary to SSc. All patients were treated with US combined with manual therapy, including McMennel joint manipulation, pompage mobilization technique and connective tissue massage, for 10 sessions. We evaluated softness, dyschromia, pain, and hand mobility using the Pressure Sore Status Tool (PSST), the Numerical Rating Scale (NRS), and the Duruoz Hand Index (DHI) at T0 and at the end of the treatment (T1).

RESULTS

Treatment with US combined with manual therapy significantly reduced ulcers depth, improved ulcers margins, and reduced periwound skin damage (median PSST score 16 at T1, p<0.0001). Moreover, significant benefits were reported in terms of pain relief (NRS 3 at T1; p<0.0005), and hand function (DHI score 19 at T1; p<0.0005). Finally, this approach seems to be safe, without side effects reported at the end of treatment, along with an optimal compliance.

CONCLUSION

Therapeutic US combined with manual therapy should be used as additional intervention to manage IDUs in SSc patients.

Complex Regional Pain Syndrome in Athletes: Scoping Review

Background and Objectives: Complex regional pain syndrome (CRPS) is a chronic condition characterized by disproportionate regional pain, usually affecting distal limbs, that follows trauma or surgery. Athletes may develop CRPS because of exposure to traumatic or overuse injuries. The aim of the present study is to review the available literature about CRPS type 1 in athletes. Materials and Methods: We searched two online databases (PubMed and Web of Science), selecting papers aiming at investigating CRPS type 1 (algodystrophy) in athletes. The analysis of databases was made considering original articles published until 30 June 2021, written in English. Results: Fifteen papers (12 case reports, 3 case series) were selected for a total of 20 clinical cases (15 females, 5 males), aged between 10 and 46 years (mean age 18.4 ± 9.8 standard deviation years). Patients included practiced different types of sport (soccer, athletics, gymnastics, basketball). The most involved anatomical sites were lower limbs, and time to diagnosis ranged from 2 days to 4 years. The most used treatments were pharmacological and physical therapies, but sometimes invasive approaches, as regional nerve, or lumbar sympathetic blocks, were provided. The main assessed outcomes were return to activity and pain. Conclusions: Our review suggests a higher prevalence of CRPS type 1 in younger people and in lower limbs than in general population but confirms the higher prevalence in females. However, the number of studies addressing CRPS in athletes is limited, as well as the number of involved patients, considering that only few and heterogeneous case reports were published about this topic. Moreover, the high prevalence of old studies (only 5 available studies in the last 10 years) might have influenced the choice of both assessment tools and management strategies. Despite these limitations, athletes showing disproportionate pain after sport-related injury should be promptly evaluated and treated through a multidimensional approach to avoid long-term consequences of algodystrophy.

Physical Agent Modalities in Early Osteoarthritis: A Scoping Review

Early osteoarthritis (EOA) still represents a challenge for clinicians. Although there is no consensus on its definition and diagnosis, a prompt therapeutic intervention in the early stages can have a significant impact on function and quality of life. Exercise remains a core treatment for EOA; however, several physical modalities are commonly used in this population. The purpose of this paper is to investigate the role of physical agents in the treatment of EOA. A technical expert panel (TEP) of 8 medical specialists with expertise in physical agent modalities and musculoskeletal conditions performed the review following the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) model. The TEP searched for evidence of the following physical modalities in the management of EOA: "Electric Stimulation Therapy", "Pulsed Electromagnetic field", "Low-Level Light Therapy", "Laser Therapy", "Magnetic Field Therapy", "Extracorporeal Shockwave Therapy", "Hyperthermia, Induced", "Cryotherapy", "Vibration therapy", "Whole Body Vibration", "Physical Therapy Modalities". We found preclinical and clinical data on transcutaneous electrical nerve stimulation (TENS), extracorporeal shockwave therapy (ESWT), low-intensity pulsed ultrasound (LIPUS), pulsed electromagnetic fields stimulation (PEMF), and whole-body vibration (WBV) for the treatment of knee EOA. We found two clinical studies about TENS and PEMF and six preclinical studies-three about ESWT, one about WBV, one about PEMF, and one about LIPUS. The preclinical studies demonstrated several biological effects on EOA of physical modalities, suggesting potential disease-modifying effects. However, this role should be better investigated in further clinical studies, considering the limited data on the use of these interventions for EOA patients.

Epidemiology of Musculoskeletal Injuries in Adult Athletes: A Scoping Review

Background and Objectives: Sport-related musculoskeletal injuries (MSK-Is) are a common health issue in athletes that can lead to reduced performance. The aim of this scoping review was to synthetize available evidence on injury incidence rates (IIRs), types, and sites that affect the musculoskeletal (MSK) system of adult athletes. Materials and Methods: We performed a scoping review on the Pubmed database limiting our search to 33 Olympic sports. Results: We identified a total of 1022 papers, and of these 162 were examined in full for the purpose of this review. Archery was the sport with the highest risk of injuries to the upper extremities, marathons for the lower extremities, and triathlon and weightlifting for the body bust. In the majority of the sports examined, muscle/tendon strain and ligament sprain were the most common MSK-Is diagnoses, while athletics, karate, and football were the sports with the highest IIRs, depending on the methods used for their calculations. Conclusions: Our scoping review highlighted the general lack and dishomogeneity in the collection of data on MSK-Is in athletes.

The Role of Hyaluronic Acid in Sport-Related Tendinopathies: A Narrative Review

Tendinopathy is a complex clinical condition with a rising incidence and prevalence, particularly during sports practice. For the return to play in affected patients, adequate functional and structural recovery of the tendon is the ultimate goal, avoiding the high risk of recurrence. In this perspective, local therapies alongside exercise are showing promising results. Despite evidence suggesting hyaluronic acid (HA) injections as effective in the treatment of tendinopathy, current recommendations about the management of this condition do not include this intervention. HA seems to be an effective therapeutic option for the management of sport-related tendinopathies, but further studies with a larger sample size are needed to confirm available findings. In this narrative review, we analyzed available literature about the rationale of the use of HA in the management of tendon injury and, particularly, in sport-related tendinopathies.

Myths and Truths about Placebo Effect in Rehabilitation for Musculoskeletal Pain

This commentary provides the authors' point of view about the biopsychosocial perspective of placebo effect on musculoskeletal pain in the rehabilitation field.

Ultrasound Imaging in Sport-Related Muscle Injuries: Pitfalls and Opportunities

Muscle injuries occur frequently in athletes, accounting for more than one-third of sport-related trauma. Athletes most affected by these injuries are those practicing football and track and field, with hamstrings and gastrocnemius-soleus as the mainly involved sites. Muscle injuries lead to loss of competitions, long recovery times and risk of re-injury with a consequent increase of the management costs. It is therefore advisable to make an accurate and timely diagnosis to establish appropriate interventions for proper healing in the shortest time. In this context, ultrasound imaging is widely used for diagnosis of musculoskeletal disorders because of several advantages including absence of radiation, portability, good spatial resolution, and the ability to perform dynamic tests. The aim of this review is to address the role of US in the evaluation of athletes with muscle injuries. US may play a pivotal role for the management of sport-related muscle injuries because it is fast and relatively cheap, allowing dynamic muscle assessment and time series evaluation of the healing process.

Muscle Regeneration and Function in Sports: A Focus on Vitamin D

Muscle is one of the main targets for the biological effects of vitamin D. This hormone modulates several functions of skeletal muscles, from development to tissue repair after injury, through genomic and non-genomic mechanisms. Vitamin D deficiency and supplementation seem to significantly affect muscle strength in different populations, including athletes, although optimal serum 25(OH)D3 level for sport performance has not been defined so far. Additionally, vitamin D deficiency results in myopathy characterized by fast-twitch fiber atrophy, fatty infiltration, and fibrosis. However, less is known about regenerative effects of vitamin D supplementation after sport-related muscle injuries. Vitamin D receptor (VDR) is particularly expressed in the embryonic mesoderm during intrauterine life and in satellite cells at all stages of life for recovery of the skeletal muscle after injury. Vitamin D supplementation enhances muscle differentiation, growth, and regeneration by increasing the expression of myogenic factors in satellite cells. The objective of this narrative review is to describe the role of vitamin D in sport-related muscle injury and tissue regeneration.

Role of the Endocannabinoid/Endovanilloid System in the Modulation of Osteoclast Activity in Paget's Disease of Bone

The role of the endocannabinoid/endovanilloid (EC/EV) system in bone metabolism has recently received attention. Current literature evidences the modulation of osteoclasts and osteoblasts through the activation or inhibition of cannabinoid receptors in various pathological conditions with secondary involvement of bone tissue. However, this role is still unclear in primary bone diseases. Paget's disease of the bone (PDB) could be considered a disease model for analyzing the role of the EC/EV system on osteoclasts (OCs), speculating the potential use of specific agents targeting this system for managing metabolic bone disorders. The aim of the study is to analyze OCs expression of EC/EV system in patients with PDB and to compare OCs activity between this population and healthy people. Finally, we investigate whether specific agents targeting EC/EV systems are able to modulate OCs activity in this metabolic bone disorder. We found a significant increase in cannabinoid receptor type 2 (CB2) protein expression in patients with PDB, compared to healthy controls. Moreover, we found a significant reduction in multi-nucleated tartrate-resistant acid phosphatase (TRAP)-positive OCs and resorption areas after treatment with JWH-133. CB2 could be a molecular target for reducing the activity of OCs in PDB, opening new therapeutic scenarios for the management of this condition.

Complex Regional Pain Syndrome Type I Following Non-Orthopedic Surgery: Case Report and Narrative Review

Complex regional pain syndrome type I (CRPS I)-or algodystrophy-is a rare disease that usually occurs after a traumatic event. It is characterized by typical clinical findings such as severe and disabling pain disproportionate to the injury, functional limitations, as well as sensory and vasomotor alterations. However, some people do not report any injury associated with algodystrophy onset in personal history. We describe the management of an unusual case of CRPS I which occurred during the long-term follow-up of percutaneous transluminal coronary angioplasty (PTCA) and performed a narrative review of algodystrophy in non-orthopedic surgery. A clinical case of a 44-year-old man with a spontaneous onset of CRPS I of the right ankle is presented. He did not refer to history of any memorable significant trigger event. Approximately 5 months before the onset of clinical manifestations, he received a PTCA via the right femoral approach. We suppose an association between CRPS and this procedure and propose a possible pathophysiologic mechanism. The patient was treated with intramuscular neridronate, which resulted in significant pain relief and improved his quality of life. A comprehensive clinical and instrumental evaluation in patients with CRPS is challenging but mandatory for a correct diagnosis. An extensive analysis of patient history is important for identifying any potential trigger event, including non-orthopedic procedures. Bone scan could have a pivotal role for improving diagnostic sensitivity and specificity in CRPS I. Neridronate was a safe and effective therapeutic approach for this patient, confirming the results of the high-quality evidence available.

Natural History of Scoliosis in Children with NF1: An Observation Study

(1) Background. Scoliosis is the most common musculoskeletal manifestation of Neurofibromatosis type 1 (NF1), and it might be dystrophic (D) or non-dystrophic (ND) depending on the presence of dysplastic changes of the spine. The aim of our study was to describe the characteristics and natural history of patients with NF1 and scoliosis. (2) Methods. We retrospectively reviewed records from patients with NF1 and scoliosis. Scoliosis was classified as D if at least two dystrophic changes were documented at imaging. (3) Results. Of the 438 patients reviewed, 43 fulfilled inclusion criteria; 17 were classified in D group and 26 in ND. The groups did not differ in age and localization of scoliosis curvature. Surgery was needed more often in D group, but the between-group difference was not significant. Male-to-female ratios of 3:1 and 4:1 were reported in surgically treated NF1 patients with ND and D scoliosis, respectively. (4) Conclusions. Our data suggests independently by the presence of dysplastic changes affecting the spine that males with NF1 are more often affected by scoliosis that requires surgery.

Personalized paths for physical activity: developing a person-centered quantitative function to determine a customized amount of exercise and enhancing individual commitment

BACKGROUND

Non-Communicable Diseases (NCDs) are leading causes of mortality. These conditions are also known as chronic diseases of long duration and generally slow progression. Physical activity (PA) is a main factor to delay symptoms and consequences of NCDs. In last decades, reduced physical exercise has been observed across all ages. Despite educational campaigns aimed at modifying unhealthy habits, it is difficult to promote healthy lifestyles in general population. Poor interest, lack of motivation, as well as career and family commitments hinder people's participation in regular PA programs. In this study we propose a theoretical person-centred approach to actively involve general population in enhancing their opportunity to perform PA based on personalized needs and targets.

METHODS

We defined four profiles of baseline PA levels (inactive, moderately inactive, moderately active, and active people) by referring to Metabolic equivalents (METs) based on individual answers to General Practice Physical Activity Questionnaire (GPPAQ).

RESULTS

Based on the answers to the GPPAQ and by computing the related METs for each profile of baseline exercise levels, we developed an innovative person-centered web-based algorithm/function for enhancing and measuring PA participation in community settings. This function can compute evidence-based standardized profiles of participants, personalized goals of PA being functional to the purpose of maintaining or gaining health benefits, as well as the type and duration of PA needed to reach these goals.

CONCLUSION

It might be speculated that this approach would be a reliable method for increasing people's self-efficacy and population adherence to recommended levels of PA. However, this theoretical proposal requires to be implemented in further research.

Osteoporosis guidelines from a rehabilitation perspective: systematic analysis and quality appraisal using AGREE II

INTRODUCTION

People affected by osteoporosis and fragility fractures often report disability and poor health-related quality of life. Albeit rehabilitation has a crucial role in older people, post-menopausal women and other subjects with high risk of fragility fractures, the rehabilitation perspective has been poorly investigated in the available guidelines for osteoporosis. The aim of this systematic review was to systematically evaluate the quality of guidelines for osteoporosis from a rehabilitation perspective.

EVIDENCE ACQUISITION

On May 2020, we performed a systematic search on medical literature of all guidelines published in the last 10 years on PubMed, Pedro, and international guideline databases. The study selection was based on key terms "exercise," "physical activity" or "rehabilitation." All authors independently assessed the methodological quality through the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument, consisting of six domains (scope, stakeholder involvement, rigor and development, clarity of presentation, applicability, editorial independence).

EVIDENCE SYNTHESIS

Out of 331 documents retrieved, a total of 34 guidelines were selected after the screening phases. Twenty (58.8%) high quality guidelines were reported. According to AGREE II instrument, a mean score of 78.1±21.8% was reported for "scope and purpose" domain; for stakeholder involvement, the mean score was 58.1±22.1%; the rigor of development was good (mean score of 61.3±27.3%); for clarity of presentation the mean score was 79.4±20.3%; the applicability was poor (mean score of 30.9±25.2%); for editorial independence the mean score was 75.1±24.6%. Rehabilitation recommendations for osteoporotic patients were reported in 21 (61.8%) of the selected guidelines.

CONCLUSIONS

This is the first systematic analysis evaluating quality of the guidelines for osteoporosis using AGREE II instrument. Starting from a state of the art of the currently available evidence, we could conclude that therapeutic exercise at moderate to high intensity is encouraged by several guidelines for the management of people with osteoporosis and fragility fractures. More than half of guidelines were of high-quality. However, most guidelines are lacking specific indications about exercise features. This study might support the implementation of a rehabilitation perspective in the guidelines for osteoporotic patients.

The role of bone anabolic drugs in the management of periodontitis: a scoping review

The aim of this scoping review was to summarise current knowledge about the effects of bone anabolic drugs on periodontitis, in order to identify new therapeutic strategies for preventing disease progression and reducing tooth loss. A technical expert panel (TEP) was established of 11 medical specialists, including periodontists and bone specialists that followed the PRISMA-ScR model to perform the scoping review and considered for eligibility both pre-clinical and clinical studies published in the English language up to September 2020. 716 items were initially found. After duplicate removal and screening of articles for eligibility criteria, 25 articles published between 2001 and 2019 were selected. Only studies concerning teriparatide, strontium ranelate, sclerostin antibodies and DKK1 antibodies met the eligibility criteria. In particular, only for teriparatide were there both clinical studies and experimental studies available, while for other bone anabolic drugs only animal studies were found. Available evidence about the use of bone anabolic drugs in periodontology demonstrates beneficial effects of these agents on biological pathways and histological parameters involved in periodontal tissue regeneration that suggest relevant clinical implications for the management of periodontitis.

The Rationale for the Intra-Articular Administration of Clodronate in Osteoarthritis

BACKGROUND

Several pharmacological therapeutic approaches have been proposed to manage osteoarthritis (OA), including intra-articular (IA) injections. Although the discovery of clodronate, a bisphosphonate, dates back to the 1960s and the effects of its IA administration have been investigated for decades in animal models, mechanisms of action of this drug are not quite clear, particularly in OA. This scoping review is an overview of the biological as well as the clinical role of clodronic acid in OA.

METHOD

A scoping review based on the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) model was performed to characterize the mechanisms of action of IA clodronate in OA and to evaluate its efficacy from a clinical point of view.

RESULTS

Several effects of clodronate have been observed in animal models of OA, including depletion of synovial lining cells that results in reduced production of chemokines (IL-1, TNF- α), growth factors (TGF-β, BMP 2/4), and metalloproteases (MMP 2/3/9); prevention of cartilage damage, synovial hyperplasia, and proteoglycans loss; reduction in joint inflammation, joint swelling, and osteophyte formation. From a clinical perspective, patients with knee OA treated with IA clodronate experienced improvements in pain and joint mobility.

CONCLUSION

Clodronate appears to have different mechanisms of action interfering with the pathogenic processes contributing to OA development and progression. This intervention demonstrated positive effects for patients affected by knee OA.

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.

Efficacy and Effectiveness of Physical Agent Modalities in Complex Regional Pain Syndrome Type I: A Scoping Review

Complex regional pain syndrome type I (CRPS-I) is a rare condition with huge variability in triggering factors and clinical scenarios. The complexity of the pathophysiology of this condition fosters the proposal of several therapeutic options with different mechanisms of action in both research and clinical practice. An interdisciplinary and multimodal approach, including pharmacological and non-pharmacological interventions, particularly physical therapy, is recommended by international guidelines, but the benefits and harms of available interventions are poorly known. In this scoping review, the clinical rationale for use of physical agent modalities for patients with CRPS-I will be presented. We found 10 studies addressing the role of electromagnetic field therapy, electrotherapy, and laser therapy. Our findings suggest that physical therapy modalities, in particular transcutaneous electrical nerve stimulation (TENS) and pulsed electromagnetic field therapy (PEMF), may contribute to reduce pain and improve function in patients with CRPS-1.

Rehabilitation of Neuromuscular Diseases During COVID-19: Pitfalls and Opportunities

The outbreak of COVID-19 caused by SARS-CoV-2 has spread worldwide with a huge impact on the healthcare system. Compared to the previous coronaviruses-related pandemics, COVID-19 is more transmissible with potential systemic involvement and peculiar neurological manifestations, such as Guillan-Barrè syndrome up to critical illness myopathy, occurring in the intensive care setting. In this clinical scenario, people living with a neuromuscular disease (NMD) represent a vulnerable category with a high risk of a severe course of COVID-19. Moreover, in the NMD population, the management of respiratory and muscular impairments after SARS-CoV-2 infection might be troubling in terms of both pharmacological and rehabilitative approaches. To date, rehabilitation is still an unmet need in this population with several implications on NMD progression with and without SARS-CoV-2 infection. In particular, rehabilitation intervention for patients with NMD after COVID-19 are lacking. Therefore, in the current paper, we analyze the critical issues of COVID-19 on NMDs patients and propose a home-based rehabilitation program targeted for this population after mild to moderate SARS-CoV-2 infection.

Cross Cultural Adaptation and Validation of Italian Version of the Leeds Assessment of Neuropathic Symptoms and Signs Scale and Pain DETECT Questionnaire for the Distinction between Nociceptive and Neuropathic Pain

OBJECTIVE

This study aimed to validate Italian versions of Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) scale and Pain DETECT questionnaire (PD-Q) and evaluate the ability of these questionnaires to discriminate between nociceptive and neuropathic pain.

DESIGN

Multicenter prospective validation cohort study. Subjects and Setting. One hundred patients were included with a diagnosis formulated by a specialist in outpatient settings (50 affected by knee osteoarthritis as nociceptive pain and 50 affected by trigeminal or postherpetic neuralgia as neuropathic pain).

METHODS

The Italian versions of both questionnaires according to Italian cultural characteristics were performed according to the following steps: (1) translation of the questionnaires from English into Italian; (2) review by a bilingual individual for consistency; (3) proposed version after a mail round between experts; (4) backward translation; (5) comparison with the original English version by the experts; (6) approved version of the questionnaires. One hundred patients were enrolled and completed the two questionnaires administered by a specialist or blinded nursing staff, at the baseline and after 24/48 hours. Internal consistency, stability, validity, and discriminative power were analyzed.

RESULTS

Statistically significant differences were reported about the ability of both questionnaires to discriminate between patients affected by neuropathic or nociceptive pain. Internal consistency for the Italian version of the LANSS was 0.76, and for PD-Q, it was 0.80, assessed by Cronbach's α; LANSS showed a good test-retest reliability with an ICC of 0.76, and PD-Q showed a high test-retest reliability with an ICC of 0.96. For interrater reliability, there was a concordance rate of 83.3% between reference diagnosis and LANSS (Cohen's kappa = 0.67, CI 95% 0.52-0.75).

CONCLUSIONS

This study validated the Italian versions of LANSS and PD-Q as reliable instruments with good psychometric characteristics, for pain evaluation, discriminating between nociceptive and neuropathic pain. Our findings were similar to those observed in the original study. Furthermore, we have reported the test-retest reliability for both questionnaires, not addressed in original validation studies.

Non-motor impairments affect walking kinematics in Parkinson disease patients: A cross-sectional study

BACKGROUND

In patients with Parkinson disease (PD), severe postural and gait impairments are rarely observed in early stage of disease and non-motor symptoms (NMS) are often overlooked.

OBJECTIVE

This observational study aimed to characterize the impact of non-motor impairments on walking kinematics in early stages PD patients, and to assess the differences of gait parameters and NMS between PD patients with and without mild cognitive impairment (MCI).

METHODS

Twenty-six patients with Modified Hoehn and Yahr Scale score≤2 were evaluated for NMS using Kings Parkinson's Pain Scale, Parkinson Fatigue Severity scale, Parkinson Anxiety Scale, Beck Depression Inventory and Epworth Sleepiness Scale, kinematic parameters through an inertial sensor and cognitive performance by a comprehensive neuropsychological battery.

RESULTS

Fatigue had a moderate negative correlation with step cadence, and a moderate to strong positive correlation with gait duration, Timed Up and Go (TUG) and TUG Dual Task (p < 0.01). Pain showed positive moderate correlation with gait duration (p < 0.01). Twelve patients resulted affected by MCI and reported significantly worse scores in gait duration, pain and fatigue (p < 0.05). According to cognitive z scores, PD-MCI group showed a moderate negative correlation between visuospatial abilities and fatigue (p < 0.05).

CONCLUSIONS

NMS significantly affect walking kinematics whereas a limited role of cognitive status on motor performance occur in the early PD stages.

Fractures around Trochanteric Nails: The "Vergilius Classification System"

INTRODUCTION

The fractures that occurred around trochanteric nails (perinail fractures, PNFs) are becoming a huge challenge for the orthopaedic surgeon. Although presenting some specific critical issues (i.e., patients' outcomes and treatment strategies), these fractures are commonly described within peri-implant ones and their treatment was based on periprosthetic fracture recommendations. The knowledge gap about PNFs leads us to convene a research group with the aim to propose a specific classification system to guide the orthopaedic surgeon in the management of these fractures.

MATERIALS AND METHODS

A steering committee, identified by two Italian associations of orthopaedic surgeons, conducted a comprehensive literature review on PNFs to identify the unmet needs about this topic. Subsequently, a panel of experts was involved in a consensus meeting proposing a specific classification system and formulated treatment statements for PNFs. Results and Discussion. The research group considered four PNF main characteristics for the classification proposal: (1) fracture localization, (2) fracture morphology, (3) fracture fragmentation, and (3) healing status of the previous fracture. An alphanumeric code was included to identify each characteristic, allowing to describe up to 54 categories of PNFs, using a 3- to 4-digit code. The proposal of the consensus-based classification reporting the most relevant aspects for PNF treatment might be a useful tool to guide the orthopaedic surgeon in the appropriate management of these fractures.

Systematic review of clinical practice guidelines for adults with fractures: identification of best evidence for rehabilitation to develop the WHO's Package of Interventions for Rehabilitation

BACKGROUND

The identification of existing rehabilitation interventions and related evidence represents a crucial step along the development of the World Health Organization's (WHO) Package of Interventions for Rehabilitation (PIR). The methods for such identification have been developed by the WHO Rehabilitation Programme and Cochrane Rehabilitation under the guidance of the WHO's Guideline Review Committee secretariat. The aim of this paper is to report on the results of the systematic search for clinical practice guidelines (CPGs) relevant to the rehabilitation of adults with fractures and to present the current state of evidence available from the identified CPGs.

METHODS

This paper is part of the Best Evidence for Rehabilitation (be4rehab) series, developed according to the methodology presented in the World Health Organization's (WHO) Package of Interventions for Rehabilitation (PIR) introductory paper. It is a systematic review of existing CPGs on fractures in adult population published from 2009 to 2019.

RESULTS

We identified 23 relevant CPGs after title and abstract screening. According to inclusion/exclusion criteria, we selected 13 CPGs. After checking for quality, publication time, multiprofessionality, and comprehensiveness, we finally included five CPGs dealing with rehabilitative management of fractures in adult population, two CPGs addressing treatment of distal radius fracture and three the treatment of femoral/hip fracture.

CONCLUSION

The selected CPGs on management of distal radius and femoral/hip fracture include few recommendations regarding rehabilitation, with overall low to very low quality of evidence and weak/conditional strength of recommendation. Moreover, several gaps in specific rehabilitative topics occur. Further high-quality trials are required to upgrade the quality of the available evidence.

LEVEL OF EVIDENCE

Level 1.

The perspectives of intra-articular therapy in the management of osteoarthritis

Management of Osteoarthritis (OA) still is a challenge for clinicians. Taking into account a multidisciplinary approach including pharmacological and non-pharmacological treatments, intra-articular (IA) injection could be considered as an effective local therapy. Areas covered This review provides a new perspective of IA treatment going beyond current available IA agents. We describe novel biological targets for developing new IA agents and innovative modalities of delivery systems. Additional topics include predictors of response for a better choice of IA agents for each patient, diagnostic and prognostic role of biomarkers, accuracy of IA injection, and cost-effectiveness of IA injection. Expert opinion IA treatments seem to be very promising for the management of OA. Identifying clinical and biochemical predictive factors could drive clinician to the appropriate therapeutic approach. To date, there is a gap regarding the benefit of IA treatments in the 'real practice' once they have been adopted. However, considering these promising effects of IA approach, several open questions remain not clarified.

Characterization of Home Working Population during COVID-19 Emergency: A Cross-Sectional Analysis

Evidence about the characterization of home workers in terms of both work-related outcomes and health issues is lacking. The purpose of this cross-sectional study was to examine the impact of home working on perceived job productivity and satisfaction, work-related stress, and musculoskeletal (MSK) issues. We included 51 mobile workers, collecting data about demographic characteristics, working experience, job productivity, and stress. Job satisfaction was assessed through the Utrecht Work Engagement Scale (UWES), while MSK pain was investigated by the Brief Pain Inventory (BPI) and Fear Avoidance Beliefs Questionnaire (FABQ). Moreover, a home workplace analysis had to be carried out according to current Italian regulations. Participants declared that they were less productive (39.2%) but less stressed (39.2%) and equally satisfied (51%) compared to the time of office working. Regarding MSK disorders, low back pain (LBP) was referred by 41.2% of home workers and neck pain by 23.5% of them. Neck pain worsened in 50% of home workers, while LBP did not exacerbate in 47.6% of cases. Home workers with MSK pain reported a lower job satisfaction. Depending on our data, the home environment seems to be not adequate in the mobile worker population, with an increased risk for mental health and MSK problems, particularly affecting the spine. Addressing these issues can significantly reduce risks for health, thus, improving job productivity and satisfaction and reducing cost.

Transient osteoporosis of the hip and subclinical hypothyroidism: an unusual dangerous duet? Case report and pathogenetic hypothesis

BACKGROUND

Transient osteoporosis of the hip (TOH) is a rare and temporary clinical condition characterised by bone marrow edema (BME), severe pain, and functional limitation. It commonly occurs in middle-aged men or in women in the last trimester of pregnancy. TOH usually resolves with conservative therapy but may predispose to hip fracture or progression to avascular necrosis (AVN). Etiology is still unclear, although several pathophysiological mechanisms underpinning this condition has been proposed. We describe the management of an unusual case of TOH occurred in a patient with subclinical hypothyroidism.

CASE PRESENTATION

A clinical case of a 46-year-old man with severe pain in the left anterior thigh is presented. After a comprehensive clinical and radiological approach, a TOH was diagnosed. Moreover, biochemical assessment suggested the presence of subclinical hypothyroidism. After 3 months of treatment with clodronate, physical therapy and hormone replacement therapy (HRT) a significant improvement of clinical and radiological outcomes was observed.

CONCLUSION

Several pathological conditions have been related to development of TOH. In our case, we suggested for the first time a role of subclinical hypothyroidism as novel contributory factor for the onset of this condition, providing pathophysiological mechanisms and a scientific rationale for pharmacological treatment.

Choline: An Essential Nutrient for Skeletal Muscle

BACKGROUND

Choline is an essential micronutrient with a pivotal role in several metabolic pathways contributing to liver, neurological, and hematological homeostasis. Although choline is commonly administered to improve physical performance, its effects on muscle are still unclear. The aim of this scoping review is to analyze the role of choline on skeletal muscle in terms of biological effects and clinical implications.

METHODS

A technical expert panel (TEP) of 6 medical specialists with expertise in muscle physiology and skeletal muscle disorders performed the review following the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) model. The TEP planned a research on PubMed selecting "choline" as MeSH (Medical Subject Headings) term adding to PubMed Search Builder the terms "skeletal muscle" and "muscle striated". TEP considered for eligibility articles published in the last 30 years, including original researches, particularly in vitro studies, and animal and clinical studies in the English language.

RESULTS

From the 1239 studies identified, TEP included 14 studies, 3 in vitro, 9 animal, and 2 clinical studies.

CONCLUSIONS

Our scoping review elucidates and summarizes the crucial role of choline in modulating muscle fat metabolism, muscle proteins homeostasis, and the modulation of inflammation and autophagy.

Adapted physical activity and therapeutic exercise in late-onset Pompe disease (LOPD): a two-step rehabilitative approach

Aerobic exercise, training to sustain motor ability, and respiratory rehabilitation may improve general functioning and quality of life (QoL) in neuromuscular disorders. Patients with late-onset Pompe disease (LOPD) typically show progressive muscle weakness, respiratory dysfunction and minor cardiac involvement. Characteristics and modalities of motor and respiratory rehabilitation in LOPD are not well defined and specific guidelines are lacking. Therefore, we evaluated the role of physical activity, therapeutic exercise, and pulmonary rehabilitation programs in order to promote an appropriate management of motor and respiratory dysfunctions and improve QoL in patients with LOPD. We propose two operational protocols: one for an adapted physical activity (APA) plan and the other for an individual rehabilitation plan, particularly focused on therapeutic exercise (TE) and respiratory rehabilitation.

Do Dietary Supplements and Nutraceuticals Have Effects on Dental Implant Osseointegration? A Scoping Review

Several factors affect dental implant osseointegration, including surgical issues, bone quality and quantity, and host-related factors, such as patients' nutritional status. Many micronutrients might play a key role in dental implant osseointegration by influencing some alveolar bone parameters, such as healing of the alveolus after tooth extraction. This scoping review aims to summarize the role of dietary supplements in optimizing osseointegration after implant insertion surgery. A technical expert panel (TEP) of 11 medical specialists with expertise in oral surgery, bone metabolism, nutrition, and orthopedic surgery performed the review following the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) model. The TEP identified micronutrients from the "European Union (EU) Register of nutrition and health claims made on foods" that have a relationship with bone and tooth health, and planned a PubMed search, selecting micronutrients previously identified as MeSH (Medical Subject Headings) terms and adding to each of them the words "dental implants" and "osseointegration". The TEP identified 19 studies concerning vitamin D, magnesium, resveratrol, vitamin C, a mixture of calcium, magnesium, zinc, and vitamin D, and synthetic bone mineral. However, several micronutrients are non-authorized by the "EU Register on nutrition and health claims" for improving bone and/or tooth health. Our scoping review suggests a limited role of nutraceuticals in promoting osseointegration of dental implants, although, in some cases, such as for vitamin D deficiency, there is a clear link among their deficit, reduced osseointegration, and early implant failure, thus requiring an adequate supplementation.

Pharmacological Therapy of Osteoporosis: What's New?

Osteoporosis and fragility fractures are relevant health issues because of their impact in terms of morbidity, mortality, and socioeconomic burden. Despite this alarming scenario, both underdiagnosis and undertreatment are common features of osteoporotic patients, particularly those who have already sustained a fragility fracture. Pharmacotherapy of osteoporosis is the main treatment option for these patients because of strong evidence about the efficacy of available drugs targeting bone metabolism. However, several issues can interfere with the effectiveness of anti-osteoporotic drugs in clinical practice, such as lack of awareness of both healthcare providers and patients, poor adherence to therapy, and safety in long-term treatment. Therefore, new therapeutic strategies have been proposed to overcome these problems, such as sequential therapy or emerging molecules mainly targeting the stimulation of bone formation. In particular, abaloparatide has been demonstrated to reduce major nonvertebral fracture risk compared with both placebo and teriparatide, although the European Medicines Agency (EMA) refused the marketing authorization because the benefits of this drug did not outweigh its risks. On the other side, EMA has recently approved romosozumab, a monoclonal antibody directed against sclerostin and the only available therapeutic option targeting Wnt signaling, as both bone-forming and antiresorptive intervention to treat osteoporosis and fragility fractures.

Multifactorial Assessment of Risk of Falling in 753 Post-Menopausal Women: A Multicenter Cross-Sectional Study by the Italian Group for the Study of Metabolic Bone Diseases

OBJECTIVE

To assess physical performance, number of falls, previous fragility fractures, and ongoing pharmacological therapy in a cohort of post-menopausal women, according to their risk of falling.

METHODS

In this multicenter cross-sectional study, we recruited in a 3-year period (May 2016 to April 2019), women aged >60 years referred to seven Osteoporosis and Bone Metabolism Outpatient Services of the Italian Group for the Study of Metabolic Bone Diseases. The study population was divided into three groups according to the risk of falling, assessed through the Elderly Fall Screening Test (EFST): low risk (EFST score=0-1); moderate risk (EFST=2-3); high risk (EFST=4-5). Outcome measures were: 4-meter gait speed (4MGS); unipedal stance time (UST); number of falls in the previous year; previous fragility fractures; ongoing pharmacological therapy.

RESULTS

We analyzed 753 women (mean aged 70.1±9.2 years): 378 (50.2%) at low risk of falling, 247 (32.8%) at moderate risk, and 128 (17.0%) at high risk. 4MGS and UST resulted as pathological in the 93.9% and 99.2%, respectively, of women at high risk. There were significant differences among groups for both outcomes (p<0.001). There was also a significant difference among groups (p<0.001) in terms of previous falls and fragility fractures. Lastly, there were significant differences (p<0.05) among groups in using antihypertensive drugs, antiplatelet agents, anticoagulants, antidepressants, anti-osteoporotic drugs, and vitamin D, and/or calcium supplementation.

CONCLUSION

Physical performance, prevalence of falls and fragility fractures, and an assessment of pharmacological therapy should be investigated in post-menopausal women because of their significant correlation with risk of falling.

Neglected femoral neck fractures in cerebral palsy: a narrative review

Hip fractures are severe conditions with a high morbidity and mortality, especially when the diagnosis is delayed, and if formulated over 30 days after the injury, is termed a 'neglected femoral neck fracture' (NFNF).Cerebral palsy (CP) is probably one of the major risk factors for NFNF in Western countries, mainly because of both cognitive and motor impairments. However, considering the high prevalence of fractures in these patients, the incidence of NFNF in this population is probably underestimated, and this condition might result in persistent hip or abdominal pain.Several techniques are available for the treatment of NFNF (i.e. muscle pedicle bone graft, fixation with fibular graft, valgisation osteotomy), but most of them could affect motor function.Motor function must be preserved for as long as possible, in order to enhance the quality of life of CP patients.After discussing published NFNF cases in CP patients and available treatment options, a practical approach is proposed to facilitate the orthopaedic surgeon to both early identify and appropriately manage these challenging fractures.

Neuromuscular Diseases and Bone

Neuromuscular diseases (NMDs) are inherited or acquired conditions affecting skeletal muscles, motor nerves, or neuromuscular junctions. Most of them are characterized by a progressive damage of muscle fibers with reduced muscle strength, disability, and poor health-related quality of life of affected patients. In this scenario, skeletal health is usually compromised as a consequence of modified bone-muscle cross-talk including biomechanical and bio-humoral issues, resulting in increased risk of bone fragility and fractures. In addition, NMD patients frequently face nutritional issues, including malnutrition due to feeding disorders and swallowing problems that might affect bone health. Moreover, in these patients, low levels of physical activity or immobility are common and might lead to overweight or obesity that can also interfere with bone strength features. Also, vitamin D deficiency could play a critical role both in the pathogenesis and in the clinical scenario of many NMDs, suggesting that its correction could be useful in maintaining or enhancing bone health, especially in the early phases of NMDs. Last but not least, specific disease-modifying drugs, available for some NMDs, are frequently burdened with adverse effects on bone tissue. For example, glucocorticoid therapy, standard of care for many muscular dystrophies, prolongs long-term survival in treated patients; nevertheless, high dose and/or chronic use of these drugs are a common cause of secondary osteoporosis. This review addresses the current state of knowledge about the factors that play a role in determining bone alterations reported in NMDs, how these factors can modify the biological pathways underlying bone health, and which are the available interventions to manage bone involvement in patients affected by NMDs. Considering the complexity of care of these patients, an interdisciplinary and multimodal management strategy based on both pharmacological and non-pharmacological interventions is recommended, particularly targeting musculoskeletal issues that are closely related to functional independence as well as social implications.

Bone alterations in inflammatory bowel diseases

Inflammatory bowel diseases (IBDs) are characterized by a multifactorial partially unknown etiology that involves genetic, immunological and environmental factors. Up to 50% of IBD patients experience at least one extraintestinal manifestation; among them is the involvement of bone density which is referred to as metabolic bone disease (MBD), including osteopenia and osteoporosis. Bone alterations in IBDs population appear to have a multifactorial etiology: Decreased physical activity, inflammation-related bone resorption, multiple intestinal resections, dietary malabsorption of minerals and vitamin D deficiency, genetic factors, gut-bone immune signaling interaction, steroid treatment, microbiota and pathogenic micro-organisms interaction, and dietary malabsorption of minerals, that, all together or individually, may contribute to the alteration of bone mineral density. This review aims to summarize the prevalence and pathophysiology of metabolic bone alterations in IBD subjects outlining the main risk factors of bone fragility. We also want to underline the role of the screening and prophylaxis of bone alterations in Crohn’s disease and ulcerative colitis patients and the importance of treating appropriately MBD.

Pharmacotherapeutic options for complex regional pain syndrome

INTRODUCTION

Complex regional pain syndromes (CRPS) are rare painful conditions characterized by considerable variability in possible triggering factors, usually traumatic, and in the clinical scenario. The limited knowledge of the pathophysiological mechanisms has led to countless treatment attempts with multiple conservative and surgical options that act by different mechanisms of action.

AREAS COVERED

In this narrative review, the authors discuss key points about CRPS definitions, diagnostic criteria and pitfalls, pathophysiological hypotheses, and treatment strategies with particular reference to pharmacotherapy. The article was based on a literature search using PubMed while the available guidelines for the management of CRPS were also examined.

EXPERT OPINION

According to the quality of evidence, pharmacological interventions for CRPS seem to be more effective all the more so when they act on peripheral mechanisms, particularly on nociceptive pain, and when applied early in the disease, while reliable evidence about central mechanisms of chronic pain in CRPS is lacking. In our opinion, drug therapy should be preferred as early as possible, particularly in warm forms of CRPS to prevent significant functional limitation, psychological distress, and social and economic fallout.

Stentoplasty of calcaneal fractures: Surgical technique and early outcomes

Calcaneus is the most common site of hindfoot fracture, frequently caused by fall from height or high energy trauma. The therapeutic strategy ranged from non-operative to ORIF (Open Reduction Internal Fixation). Indications for percutaneous fixation include soft tissue damage or relative contraindications to open surgery. Minimally invasive percutaneous calcaneoplasty should be an alternative to ORIF aiming to reach a stable reduction, early functional recovery and short hospital stay. The aim of our study was to evaluate the clinical and radiographic outcomes of calcaneus fractures treated with balloon calcaneoplasty (BCP) by using a new generation vertebral augmentation system, VBS™-Vertebral Body Stent-DePuy Synthes. A total of 10 patients treated with VBS™ system were recruited for the study. Nine fractures were caused by a fall from height and one case by traffic accident. The mean follow-up was 8.9 months (range 2.6-23.1). The fractures were categorized according to Sanders and Essex-Lopresti classifications (5: type II, 3: type III and 2: type IV; 9: "joint depression" type and 1 case "tongue" type). Radiographic measurement (Böhler's and Gissane's angles) were evaluated at both pre-operative and immediate postoperative time. The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot score as well as a subjective evaluation (Visual Analog Scale, VAS) were used for the clinical assessment at the last follow-up. Mean preoperative Böhler's angle was 12.3 ± 8.41° (95% CI 6.3-18.3°), whereas mean preoperative Gissane's angle was 123.66 ± 20.47° (95% CI 109.0-138.3°). At postoperative follow-up mean Böhler's angle increased to 21.51 ± 4.17° (95% CI 18.5-24.5°; p < 0.01), and mean postoperative Gissane's angle was 121.74°±6.82° (95% CI 116.8°-126.6°). Mean AOFAS at the last follow-up was 70.4 ± 17.44 (95% CI 57.9-82.8). Our study demonstrates that percutaneous calcaneoplasty using VBS™ is an effective treatment for calcaneus fracture and capable to implement correction manoeuvre with clinical and radiographic outcomes comparable with other percutaneous stentoplasty.

Mapping the primary outcomes reported in Cochrane systematic reviews regarding stroke with the International Classification of Functioning, Disability and Health domains: current trend and future recommendations

BACKGROUND

The International Classification of Functioning, Disability and Health (ICF) serves as a framework for defining and categorizing health and functioning. ICF could be used to classify research outcomes in a systematic manner.

AIM

The aim of this study was to classify the primary outcomes used in Cochrane Systematic Reviews (CSRs) into the ICF domains of functioning; to describe the differences in primary outcomes in reviews related to rehabilitation intervention and non-rehabilitation intervention; and to describe the trend of outcome selections according year of publication.

DESIGN

Methodological paper.

POPULATION

Adult stroke population.

METHODS

We analyzed the primary outcomes used in the CSRs published by the Cochrane Stroke Review Group up to December 2017. The primary outcomes were extracted and classified into the ICF domains of functioning (body functions, body structures and activity and participation).

RESULTS

One hundred and seventy-four papers with 216 primary outcomes were included in this analysis. Less than half (102/216, 47.2%) of the outcomes could be classified into the ICF domains of functioning. For the outcomes that could be classified into the ICF domains, the majority (72/102, 70.5%) were in the activity and participation domain, followed by body functions (26/102, 25.5%) and body structures (4/102, 4.0%). Of the outcomes that could not be classified into the ICF domains (N.=114), death (81/114, 71.1%) and recurrent stroke (21/114,18.4%) formed the majority of the outcome. There were 75 CSRs on rehabilitation related interventions; the majority of the outcomes (75/97, 77.3%) used in rehabilitation related CSRs could be classified into the ICF framework with more than half (49/75, 65.3%) in the activity and participation domain.

CONCLUSIONS

The majority of the primary outcomes selected by the Cochrane Stroke Review Group in their CSRs could not be classified into the ICF domains of functioning. Death and recurrence of vascular events remains the major outcome of interest. In rehabilitation related interventions, activity and participation domain is the functioning domain most commonly used.

CLINICAL REHABILITATION IMPACT

The systematic use of patients-centered ICF-based outcomes in CSRs could help the application of evidence in clinical decision making.

Effectiveness of denosumab on back pain-related disability and quality-of-life in patients with vertebral fragility fractures

Background: Denosumab is a fully human IgG2 monoclonal antibody that, neutralizing the receptor activator of nuclear factor kappa-Β ligand (RANKL), inhibits the osteoclast-mediated bone resorption. It is yet to be defined if denosumab can reduce osteoporosis-related disability and improve health-related quality-of-life (HRQoL) in patients with fragility fractures.Objective: To assess the effectiveness of denosumab in reducing back pain related disability and improving HRQoL in osteoporotic post-menopausal women with vertebral fractures.Research design and methods: A real practice prospective study was carried out, enrolling women over 50 years with a post-menopausal osteoporosis that experienced at least one vertebral fracture receiving subcutaneous denosumab (60 mg, every 6 months), calcium carbonate (500-1000 mg/day) and cholecalciferol (800 IU/day) for 1 year. Back pain related disability was assessed as the primary outcome using the Spine Pain Index (SPI); secondary outcomes were: SF-12 (Physical Health Composite Score, PCS, and Mental Health Composite Score, MCS), and EuroQol-5D (EuroQol-5D-3L index and EuroQol-Visual Analog Scale, EQ-VAS). All outcome measures were assessed at baseline (T0), after 6 months (T1), and after 12 months (T2) of treatment. Trabecular Bone Score (TBS), lumbar spine (LS) and femoral neck (FN) BMD at T0 and T2 were also evaluated.Results: This study included 140 post-menopausal women, mean age = 70.60 (SD = 8.81) years. There were statistically significant differences after 12 months (T2-T0) in all outcomes assessed: SPI (p < 0.001), SF-12 PCS (p < 0.001), SF-12 MCS (p < 0.001), EQ-5D-3L index (p = 0.039), and EQ-VAS (p = 0.003). Moreover, there was a significant improvement of both LS BMD (p < 0.001) and FN BMD (p < 0.001). No local or systemic adverse events, including new vertebral fractures, osteonecrosis of the jaw and atypical femur fractures, were reported.Conclusions: The data demonstrated that denosumab was effective in reducing back pain related disability and in improving HRQoL in post-menopausal women with vertebral fractures.
