Is there any relationship between scoliosis, cervical pain and postural imbalance in Parkinson's disease? A cross-sectional pilot study.

Parkinson's disease (PD) is defined by progressive worsening of gait, posture, and balance, as well as disability in daily life activities, and improvement in chronic musculoskeletal pain, particularly neck pain associated with worsening of balance. The study's goal is to look into the relationship between scoliosis, balance, and cervical pain in Parkinson's disease patients. Cross-sectional, pilot study. The study included 16 Parkinson's patients. Neck cervical pain was measured using the pain visual analogue scale and the short form McGill pain questionnaire, while dynamic balance was assessed using static balance, Tinetti, Berg Balance, and the Short Physical Performance Battery scales (SPPB). Cobb angles are measured on a whole-spine standard X-ray to assess spinal scoliosis.An observational statistical analysis was performed with patients subdivided into two groups: non-scoliosis (NS) and true scoliosis (TS) based on whether they presented a Cobb's angle below or ≥10°. Neck pain was reported by 37% (n=3) of participants in the NS group versus 50% (n=4) in the TS group. Neck pain was more prevalent in patients with a disease duration of less than 48 months (n=6; 75.0% vs n=1; 12.5%; p-value < 0.05). Scoliosis, cervical pain, and postural imbalance are all significant but often overlooked Parkinson's disease complaints.

Functional and Rehabilitative Outcomes of Patients Affected by Bone Cancer of the Upper Limb Treated with MUTARS Prosthesis: A Narrative Review.

Megaprostheses are well-known, reliable, and effective reconstruction prostheses used in oncologic surgery for limb salvage in patients affected by primary or metastatic bone tumors. Rehabilitation plays a major role after MUTARS replacement, with the aim of improving function after surgery and maintaining the highest possible quality of life. Only a few studies have been published about the use of megaprostheses for the upper limb. The aim of this narrative review is to describe the results of functional and rehabilitative outcomes of patients affected by bone primary or metastatic bone cancer of the upper limb and surgically treated with MUTARS prostheses. A comprehensive search was conducted on PubMed and Scopus using the following MESH terms: "Mutars", "Megaprosthesis", "bone", "tumors", "metastasis", "upper limb", "rehabilitation", "outcome", "quality of life", and 10 studies were included. The most frequent oncological pathology was found to be metastases of the proximal humerus treated with modular endoprosthesis or modular reverse implants. Outcome measures used were ROM, MSTS, ASES, DASH, Constant-Murley score, Enneking score, VAS, MEP, TESS, and WOSI. Reconstruction of the proximal humerus with the MUTARS system seemed to be a valid treatment option after bone tumor resection. Rehabilitation after MUTARS surgery is very relevant, but currently, functional and rehabilitative outcomes are inadequately represented in the literature. Hence, further studies are needed to define standardized rehabilitation protocols after oncological orthopedic surgery that can be applied routinely in clinical practice.

Conservative non-pharmacological treatments for chemotherapy-induced peripheral neuropathies in women treated for breast cancer: a systematic review.

INTRODUCTION: Over the last few decades, the use of neo/adjuvant therapies has significantly increased the number of breast cancer survivors who experience chemotherapy-induced peripheral neuropathy (CIPN). To date, few, low-efficacy, pharmacological remedies exist to manage this side effect. For this reason, alternative treatments are increasingly being investigated as possible strategies to prevent or promote faster recovery from CIPN. In this review we aimed to provide an overview of the literature evidence regarding all the non-pharmacological and rehabilitative interventions for patients affected by CIPN secondary to breast cancer care. EVIDENCE ACQUISITION: A comprehensive literature search was conducted on PubMed, Scopus and Web of Science and included a total of 1895 patients (1528 with breast cancer) with a wide range of CIPN (motor, sensory and autonomic neuropathies) and chemotherapy treatments (e.g., Taxanes, Platins, Vinca alkaloids or monoclonal antibody drugs). EVIDENCE SYNTHESIS: Of the initial 1108 hits, only 25 studies - describing different treatment modalities for peripheral neuropathies - were finally included in the qualitative synthesis. Most studies focused on acupuncture, physiotherapy, cryotherapy, and yoga. CONCLUSIONS: There is still controversial evidence on conservative non-pharmacological interventions for the management of CIPN symptoms. We believe however that moderate exercise, as well as all types of stress reducing activities like sport, yoga and mindfulness, should be encouraged in cancer patients for their positive effect on global physical and psychological health. Further studies of higher methodological quality are needed to determine the best conservative approach to CIPN.

Introduction to target trial emulation in rehabilitation: a systematic approach to emulate a randomized controlled trial using observational data.

Rehabilitation providers and policymakers need valid evidence to make informed decisions about the healthcare needs of the population. Whenever possible, these decisions should be informed by randomized controlled trials (RCTs). However, there are circumstances when evidence needs to be generated rapidly, or when RCTs are not ethical or feasible. These situations apply to studying the effects of complex interventions, including rehabilitation as defined by Cochrane Rehabilitation. Therefore, we explore using the target trial emulation framework by Hernán and colleagues to obtain valid estimates of the causal effects of rehabilitation when RCTs cannot be conducted. Target trial emulation is a framework guiding the design and analysis of non-randomized comparative effectiveness studies using observational data, by emulating a hypothetical RCT. In the context of rehabilitation, we outline steps for applying the target trial emulation framework using real world data, highlighting methodological considerations, limitations, potential mitigating strategies, and causal inference and counterfactual theory as foundational principles to estimating causal effects. Overall, we aim to strengthen methodological approaches used to estimate causal effects of rehabilitation when RCTs cannot be conducted.

Effects of soft tissue mobilisation on subacute adherent linear scars: a single-group intervention study.

OBJECTIVE: Scar adherence due to a pathological healing process can cause physical and psychological disturbance. Soft tissue mobilisation (STM) techniques are widely used to treat and prevent scar adherence, but little is known on their effects. We aimed to analyse the effect of STM in patients with subacute post-surgical scar adhesions affecting the extremities. METHOD: A single-group quasi-experimental study was conducted on consecutive patients undergoing post-surgery limb rehabilitation. Patients with a baseline Adhesion Severity (AS) index of <0.5 at the worst scar point, as measured by the Adheremeter, were eligible. All patients who completed a minimum of five manual treatment sessions were included. The primary outcome was the AS index and the secondary outcome was the Italian version of the Patient and Observer Scar Assessment Scales (POSAS-I). RESULTS: A cohort of 19 patients underwent an average of eight STM sessions over a period of one month. The AS index value increased from a median of 0.12 at baseline (interquartile range (IQR): 0.05-0.25) to 0.41 post-treatment (IQR: 0.26-0.63; median change: 0.24; IQR: 0.16-0.40; p<0.001). A large effect size was observed for both AS and Observer Scar Assessment Scale (OSAS-I) (Cohen r=0.6), with a large probability of superiority (PS) (87% and 86%, respectively). A moderate effect was observed for the Patient Scar Assessment Scale (PSAS-I) (Cohen=0.4; PS=71%). Pre-post treatment changes exceeded the minimal detectable changes for the AS and OSAS-I in 68% of subjects, and for PSAS-I in 21% of subjects. CONCLUSION: STM manual techniques may produce a large effect on the mobility of adherent subacute post-surgical scars.

The influence of bias in randomized controlled trials on rehabilitation intervention effect estimates: what we have learned from meta-epidemiological studies.

This study aimed to synthesize evidence from studies that addressed the influence of bias domains in randomized controlled trials on rehabilitation intervention effect estimates and discuss how these findings can maximize the trustworthiness of an RCT in rehabilitation. We screened studies about the influence of bias on rehabilitation intervention effect estimates published until June 2023. The characteristics and results of the included studies were categorized based on methodological characteristics and summarized narratively. We included seven studies with data on 227,806 RCT participants. Our findings showed that rehabilitation intervention effect estimates are likely exaggerated in trials with inadequate/unclear sequence generation and allocation concealment when using continuous outcomes. The influence of blinding was inconsistent and different from the rest of medical science, as meta-epidemiological studies showed overestimation, underestimation, or neutral associations for different types of blinding on rehabilitation treatment effect estimates. Still, it showed a more consistent pattern when looking at patient-reported outcomes. The impact of attrition bias and intention to treat has been analyzed only in two studies with inconsistent results. The risk of reporting bias seems to be associated with overestimation of treatment effects. Bias domains can influence rehabilitation treatment effects in different directions. The evidence is mixed and inconclusive due to the poor methodological quality of RCTs and the limited number and quality of studies looking at the influence of bias and treatment effects in rehabilitation. Further studies about the influence of bias in RCTs on rehabilitation intervention effect estimates are needed.

PEP mask therapy for the rehabilitation of a pre-term infant with respiratory distress syndrome: a case report.

BACKGROUND: Preterm infants can develop many complications related to organs underdevelopment. Respiratory distress syndrome (RDS) is considered the most important cause of morbidity and mortality in these patients. Traditional therapies for severe RDS, such as mechanical ventilation, come with a potential risk for pneumothorax and bronchopulmonary dysplasia while evidence on chest physiotherapy in preterm infants are controversial in terms of feasibility, tolerability and safety. The use of the positive expiratory pressure (PEP) mask is known in the pediatric field especially in cystic fibrosis for the removal of secretions and lung re-expansion. However, no literature exists on the application and effectiveness of this treatment modality for the respiratory rehabilitation of preterm infants. In this study, we aimed to assess the efficacy of a respiratory rehabilitation protocol based on PEP mask in a preterm infant with respiratory distress syndrome. CASE REPORT: A Caucasian girl born at 26 + 5 weeks of gestational age with respiratory distress syndrome was treated with mechanical ventilation, oxygen therapy and PEP-mask. CLINICAL REHABILITATION IMPACT: Three weeks of PEP mask led to a significant clinical and radiological improvement of the lung's function with progressive reduction of the oxygen supplement and mechanical ventilation until complete weaning off. Given the absence of literature on this subject, further studies should be conducted to confirm these preliminary observations.

Video-based Goniometer Applications for Measuring Knee Joint Angles during Walking in Neurological Patients: A Validity, Reliability and Usability Study.

Easy-to-use evaluation of Range Of Motion (ROM) during walking is necessary to make decisions during neurological rehabilitation programs and during follow-up visits in clinical and remote settings. This study discussed goniometer applications (DrGoniometer and Angles - Video Goniometer) that measure knee joint ROM during walking through smartphone cameras. The primary aim of the study is to test the inter-rater and intra-rater reliability of the collected measurements as well as their concurrent validity with an electro-goniometer. The secondary aim is to evaluate the usability of the two mobile applications. A total of 22 patients with Parkinson's disease (18 males, age 72 (8) years), 22 post-stroke patients (17 males, age 61 (13) years), and as many healthy volunteers (8 males, age 45 (5) years) underwent knee joint ROM evaluations during walking. Clinicians and inexperienced examiners used the two mobile applications to calculate the ROM, and then rated their perceived usability through the System Usability Scale (SUS). Intraclass correlation coefficients (ICC) and correlation coefficients (corr) were calculated. Both applications showed good reliability (ICC > 0.69) and validity (corr > 0.61), and acceptable usability (SUS > 68). Smartphone-based video goniometers could be used to assess the knee ROM during walking in neurological patients, because of their acceptable degree of reliability, validity and usability.

Rasch validation and refinement of the Lymphedema Life Impact Scale version 2 in an Italian cohort with secondary lymphedema.

PURPOSE: To produce and validate an Italian version of the Lymphedema Life Impact Scale version 2 (LLISv2-It), a tool measuring the impact of lymphedema on health-related quality of life, and investigate its main psychometric characteristics. METHODS: After translation and cross-cultural adaptation of the LLISv2, we administered it to 156 subjects with secondary lymphedema (upper or lower limb), together with (depending on the limb involved) either the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH) or the Lower Extremity Functional Scale (LEFS). We analyzed the performance of LLISv2-It using Classical Test Theory and Rasch methods. RESULTS: Cronbach alpha was 0.89. Item fit statistics indicated that item #12 was underfitting (Infit MnSQ = 1.56; Outfit MnSq = 1.75). Test-retest reliability of the 17-item version (without item #18, not scored, according to the original authors) and of a 16-item version (without #12 and #18-a unidimensional item set) were both excellent (ICC2.1 = 0.93; 95%). The minimum detectable change was 8.9 points. The correlation of LLISv2-It with DASH and LEFS was r = 0.81 and -0.57, respectively. CONCLUSIONS: The Italian version of the LLISv2 is reliable and valid. To make the tool more psychometrically sound, we recommend to not calculate items #12 and #18 in the total score.IMPLICATIONS FOR REHABILITATIONThe Lymphedema Life Impact Scale (LLISv2) is particularly useful as a validated condition-specific health-related quality of life measure for patients with chronic edema/lymphedema. We have validated its Italian version (LLISv2-It).We also examined the psychometric properties of the LLISv2 in individuals with secondary lymphedema of either upper or lower limb, using both classical test theory and Rasch techniques, to provide insights for further refinement of the questionnaire.Based on our results, we recommend not to count item #12 in the total score (besides #18, as already suggested by the original authors). Moreover, we determined that the minimum detectable change of the LLISv2 was 9 points. This information is helpful in clinical practice to understand if the change in score is not due to chance (measurement error).Although further research is warranted, the present validation study of the LLISv2 increases the confidence in the metric quality and clinical utility of the scale to assess lymphedema-specific health-related quality of life in individuals with secondary lymphedema of either upper or lower limb.

An overview of Cochrane systematic reviews for pulmonary rehabilitation interventions in people with chronic obstructive pulmonary disease: a mapping synthesis.

INTRODUCTION: There is a global unmet need for rehabilitation to meet which the World Health Organization, in collaboration with Cochrane Rehabilitation, is developing the Package of Interventions for Rehabilitation with the aim of identifying rehabilitation interventions relevant to a range of key health conditions, including chronic obstructive pulmonary disease (COPD). The purpose of this paper is to describe the best available evidence on pulmonary rehabilitation interventions for people with COPD. EVIDENCE ACQUISITION: An Overview of Cochrane Systematic Reviews (CSRs). Through the search strategy, COPD-related systematic reviews published from January 2009 to November 2021 were identified. Data were extracted on each reported outcome related to an intervention and judgements about the quality of evidence were made, using the GRADE approach. EVIDENCE SYNTHESIS: Seventeen reviews were analyzed, for a total of 314 primary studies that included 22,206 participants. CSRs provided information on the effectiveness of rehabilitation on functioning, activity, quality of life, anxiety, depression, mortality, and health care resource utilization. CONCLUSIONS: Our findings report that comprehensive pulmonary rehabilitation programs and water exercises improve the exercise capacity and quality of life (QoL) in people with COPD. Different exercise modalities, intensities, and settings for different muscle groups, breathing exercises, and counseling can improve exercise capacity, QoL, dyspnea, hospitalizations, and physical activity. It is uncertain whether breathing exercise, low-intensity exercise, neuromuscular electrical stimulation, and psychological intervention have an effect on exercise capacity, dyspnea, QoL, and physical activity. The protocol was registered on OSF (registration DOI: 10.17605/OSF.IO/8A26Q).

Trust/untrust is not the same as true/false. Lessons learned and ethical questions on the application of untrustworthiness scales to judge individuals.

This special paper reflects on trustworthiness and its implications for scientific medical journals and all the communities they serve: health professionals, policymakers, the public, and a specific discipline, in our case, Physical and Rehabilitation Medicine. We start from a recent episode: a paper claimed the untrustworthiness of two randomised controlled trials (RCTs) published in the European Journal of Physical and Rehabilitation Medicine based on a newly developed trustworthiness scale, used until now only in systematic reviews. This likely represents the first case of applying such a scale focusing on a single leading author. Developing a proper answer to this case led us to present some insights from the perspective of a Journal editor. We discuss the impact of false research results, why trust is needed in science and medicine, the difference between untrust and false results, the problems in judging trustworthiness, the unfortunately weak capacity of the peer review system in preventing these issues, the problems of "post-hoc" judgements and the emerging ethical issues. We conclude with some suggestions for the future based on prevention at the system level.

Measurement precision of the Pain Catastrophizing Scale and its short forms in chronic low back pain.

The Pain Catastrophizing Scale (PCS) is a widely studied tool to assess pain catastrophizing for chronic low back pain (LBP). Short forms of the PCS exist, but their measurement precision at individual level is unclear. This study aimed to analyze the Rasch psychometric characteristics of the PCS and three of its short forms (two 4-item and one 6-item) in a sample of 180 Italian-speaking patients with chronic LBP, and compare their measurement precision at the individual level. We performed a Rasch analysis on each version of the PCS and calculated test information functions (TIFs) to examine conditional measurement precision. Rasch analysis showed appropriate rating category functioning, unidimensionality, and acceptable fit to the Rasch model for all PCS versions. This represented a prerequisite for performing further advanced psychometric analyses. According to TIFs, the PCS full scale showed-at any score level-higher measurement precision in estimating individual pain catastrophizing than its short forms (which had unacceptably high standard errors of measurement). Our results show acceptable conditional precision of the PCS full scale in estimating pain catastrophizing. However, further studies are needed to confirm its diagnostic accuracy at individual level. On the other hand, the study warns against use of the three PCS short forms for clinical decision-making at the individual level.
