The World Report on Disability: a challenge for rehabilitation medicine

Epidemiology and Prevalence of Musculoskeletal Disabilities Following Motor Vehicle Accidents in Aljouf Region, Saudi Arabia

Background and Objectives: Motor vehicle accidents (MVAs) are the leading cause of disability, particularly among young adults in Saudi Arabia. Persistent disabilities account for around 7% of all injuries attributed to MVAs in Saudi Arabia in the last twenty years. Limited studies on musculoskeletal disabilities following MVAs have been carried out in Saudi Arabia. This study aims to explore the epidemiology and prevalence of musculoskeletal disabilities in motor vehicle accident (MVA) patients in the Aljouf region, Saudi Arabia. Materials and Methods: This retrospective cross-sectional study evaluated all MVA victims treated in the Aljouf region, Saudi Arabia, from January 2020 to December 2022. A total of 3252 medical records were collected, with 731, 1197, and 1324 musculoskeletal injury cases per year, of which 88, 168, and 153 records from 2020, 2021, and 2022 were analysed, respectively. Results: The study found that patients aged 25-34 and 35-44 years were the most likely to experience disability following MVAs. The difference between age groups during a single year was statistically significant (p < 0.001). Most patients were male (89.8%, 82.7%, and 79.7%) during 2020, 2021, and 2022, respectively. The majority of injuries involved the upper extremities (38.6%, 36.9%, and 40.5%), followed by lower extremities (36.4%, 35.7%, and 34.6%), head and neck (21.6%, 26.2%, and 34.6%), thoracic region (20.5%, 24.4%, and 17%), and finally lumbosacral spine (6.8%, 5.4%, and 6.5%) during 2020, 2021, and 2022, respectively, with a significant difference for each year (p < 0.001). The study found a link between the likelihood of developing high disability grades and injury severity scores. The patients with very severe ISS ≥ 25 (OR: ∞ CI 95%: 39.81-∞; p < 0.001), severe ISS = 16-24 (OR: ∞ CI 95%: 20.90-∞; p < 0.001), and moderate ISS = 9-15 (OR: ∞ CI 95%: 1.2-∞; p = 0.02) were at greater risk of developing high grades of disability. Conclusions: This study highlighted the musculoskeletal disabilities in the Aljouf region following MVAs. Severe musculoskeletal disabilities were rare, but fractures were the most common following MVAs. More efforts should be directed towards education on early transportation and transfer to the nearest medical centres, seeking assistance immediately after MVAs for patient safety, and disability prevention.

Do health literacy, physical health and past rehabilitation utilization explain educational differences in the subjective need for medical rehabilitation? Results of the lidA cohort study

BACKGROUND

Medical rehabilitation can be helpful for maintaining workers' health and work ability. Its contribution to longer working lives is of high economic relevance in aging populations. In Germany, individuals must apply for rehabilitative measures themselves. Therefore, the subjective need for rehabilitation (SNR) is a prerequisite for rehabilitation access. A low education level is associated with poor health, lower health literacy and more frequent utilization of health services. In the present study, we investigated whether lower educational levels are also associated with a greater SNR and whether health literacy, past rehabilitation utilization and physical health play a mediating role in this path in older employees.

METHODS

3,130 socially insured older employees (born in 1959 or 1965) who participated in the German prospective lidA (leben in der Arbeit) cohort-study in 2011, 2014 and 2018 were included. A causal mediation analysis with an inverse odds weighting approach was performed with the SNR as the dependent variable; educational level as the independent variable; and health, health literacy and past rehabilitation utilization as the mediating variables. Sociodemographic variables were adjusted for.

RESULTS

The SNR was significantly greater in subjects with a low education level, poor physical health, inadequate health literacy and those who had utilized rehabilitation in the past. For health literacy, past rehabilitation utilization and physical health, a significant partial mediating effect on the SNR was found for employees with low compared to those with high education levels. However, the combined mediating effect of all the mediators was lower than the sum of their individual effects. Among those with medium or high education levels, none of the variables constituted a significant mediator.

CONCLUSIONS

The path between a low education level and a high SNR is mediated by inadequate health literacy, past rehabilitation utilization and poor physical health; these factors do not act independently of each other. Promoting health education may lower the SNR by improving physical health and health literacy. While improving physical health is beneficial for individuals, improved health literacy can be economically advantageous for the health system by reducing inappropriate expectations of rehabilitation benefits and subsequent applications for rehabilitation.

Evaluation of an Innovative Case Management Strategy to Improve Rehabilitation Coverage for People at High Risk of Permanent Work Disability: a Feasibility Study

PURPOSE

Our process evaluation (trial registration: DRKS00022468) monitored the implementation of a multi-component strategy including case management aiming to improve rehabilitation coverage and work participation of people with a high risk of permanent work disability.

METHODS

A risk score using administrative data, particularly on employment and welfare benefits, was employed to identify individuals with higher probability of receiving disability pension and therefore potentially needing support. These individuals were contacted by post and encouraged to phone their regional case manager if they needed assistance. Content for the intervention components was developed collaboratively with the case managers. We examined the sample reached, dose delivered, fidelity, dose received and satisfaction with the intervention.

RESULTS

Out of 1074 individuals with high-risk scores were contacted, there were 57 case managements. The participants reached were in poor health, and 42.1% reported at least four diagnosed conditions, mostly musculoskeletal and mental disorders. About two-thirds (63.0%) reported poor work ability at baseline. On average, 72.5% of the content of the initial telephone contacts, 88.7% of the content of the face-to-face interviews and 45.2% of the content of the case management were delivered. The participants were highly satisfied with the various components and content of the intervention. Knowledge about rehabilitation improved significantly, with 43 of the 57 participants (75.4%) applying for rehabilitation, mainly medical rehabilitation. At the end of the case management intervention, most participants (91.7%) were still employed.

CONCLUSION

The risk score offers an opportunity to screen for people with a high risk of permanent work disability. Case management participants found participation worthwhile and were significantly better informed about participation services after completing case management. More than every second participant received medical or vocational rehabilitation.

Perioperative Outcomes, Comorbidities, and Complications following Total Shoulder Arthroplasty in Wheelchair Users: A Retrospective Cohort Analysis of a Nationwide Database

Impaired shoulder function hinders the ability of wheelchair users to maintain independence. The current state of the literature delineates the risks and benefits of surgical techniques for the management of shoulder pathologies. To the best of our knowledge, there is no study that has investigated complications following total shoulder arthroplasty (TSA) in wheelchair users. Utilizing the PearlDiver Mariner national administrative database, 72,108 patients were identified who underwent TSA with a concurrent diagnosis of a rotator cuff tear. Two matched cohorts, one of wheelchair users and one of non-wheelchair users, were created. Due to limitations within PearlDiver, one-year outcomes, including comorbidity and complication rates and readmission statistics, were compared between the two cohorts. Each matched cohort of 869 patients underwent TSA with a concurrent diagnosis of a rotator cuff tear. The rate of readmission in wheelchair users was greater than in non-wheelchair users (24.05% vs. 9.55%, OR: 3.00, CI: 2.279, 3.946). Patients in the wheelchair cohort exhibited higher rates of complications and comorbidities (p < 0.001). Among the most likely to be readmitted after TSA were patients with osteoarthritis, pulmonary heart disease, rheumatoid arthritis, and hypertension (p < 0.05). Significant differences in surgical outcomes existed between wheelchair and non-wheelchair users in terms of preoperative comorbidities, postoperative complications, and readmission rates.

[Holistic clarification of the need for intervention at the interface of rehabilitation and occupational medicine when work participation is at risk]

Introduction

For employees whose work participation is at risk, a comprehensive and workplace-oriented diagnosis is required in order to understand the health problems and to support affected persons with individual solutions. We developed a novel diagnostic service to ensure work participation that combines rehabilitative and occupational health medicine. The aim of this feasibility study was to evaluate the implementation and to analyze changes in health and working ability.

Methods

The observational study (German Clinical Trials Register: DRKS00024522) included employees with health restrictions and limited working ability. Participants received an initial consultation from an occupational health physician, a 2-day holistic diagnostics work-up at a rehabilitation center and up to four follow-up consultations. Questionnaire data collected at the initial consultation and at the first and last follow-up consultations included subjective working ability (0-10 points) and general health (0-10).

Results

Data from 27 participants were analyzed. The participants were 63% female and on average 46 years old (standard deviation, SD = 11.5). From the initial consultation to the final follow-up consultation, participants reported improvement in their general health (difference = 1.52; 95% confidence interval. CI: 0.37-2.67; d = 0.97).

Discussion and conclusion

The model project GIBI offers low-threshold access to a confidential, comprehensive and workplace-oriented diagnostic service to support work participation. Successful implementation of GIBI requires intensive cooperation between occupational health physicians and rehabilitation centers. To evaluate the effectiveness, a randomized controlled trial (n = 210) with a waiting list control group is currently underway.

Reliability of pictorial Longshi Scale for informal caregivers to evaluate the functional independence and disability

AIM

The pictorial Longshi Scale was designed to assess patients' functional ability in the Chinese context, which is gradually used by some informal caregivers. However, its reliability compared with healthcare professionals has not been examined.

DESIGN

A multi-centre cross-sectional study conducted in 24 Chinese hospitals.

METHODS

We recruited patients undergoing rehabilitation treatment and informal caregiver dyads. Informal caregivers and healthcare professionals evaluated patients' functional ability using the Longshi Scale according to three levels (bedridden, domestic and community). The Kappa coefficient and McNemar-Bowker test were used to examine the consistency and accuracy between the two parallel assessments.

RESULTS

This study involved 947 patients (mean age: 46.07 ± 11.72 years) and informal caregiver dyads (64.86 ± 12.94 years). Most patients were males (66.3%), while most caregivers were females (60.7%). Over 70% of patients and caregiver dyads had a secondary-school education and lower. Around 90% of caregivers were relatives (spouse, 42.8%; offspring, 20.7%; siblings: 13.3%; parent, 12.0%) of patients. The agreement in sub-levels of the Longshi Scale between caregivers and healthcare professionals ranges from 73%-89%, and the corresponding Kappa coefficients range from 0.504-0.786. Caregivers were more likely to assign fewer patients to the bedridden group and more to the domestic group than healthcare professionals. The subgroup analysis by education level indicated that the difference in assigning patients into three degrees of functional disability was only significant in those with primary-school education, while non-significant in those with secondary-school education and higher.

CONCLUSION

The evaluation outcomes of functional ability using the Longshi Scale are similar between informal caregivers and healthcare professionals. However, informal caregivers' education level is a dominant factor in affecting the assessment accuracy compared with healthcare professionals. Informal caregivers with a secondary-school education and higher are supported to evaluate patients' functional ability independently.

A comprehensive diagnostic service to clarify intervention needs when work participation is at risk: study protocol of a randomized controlled trial (GIBI, DRKS00027577)

Background

Effective care services for people whose work participation is at risk require low-threshold access, a comprehensive diagnostic clarification of intervention needs, a connection to the workplace and job demands, and interdisciplinary collaboration between key stakeholders at the interface of rehabilitation and occupational medicine. We have developed a comprehensive diagnostic service to clarify intervention needs for employees with health restrictions and limited work ability: this service is initiated by occupational health physicians.

Methods/design

Our randomized controlled trial tests the effectiveness of a comprehensive diagnostic service for clarifying intervention needs (GIBI: Comprehensive clarification of the need for intervention for people whose work participation is at risk). The comprehensive intervention comprises three elements: initial consultation, two-day diagnostics at a rehabilitation center and follow-up consultations. We will include 210 employees with health restrictions and limited work ability, who are identified by occupational health physicians. All individuals will receive an initial consultation with their occupational health physician to discuss their health, work ability and job demands. After this, half the individuals are randomly assigned to the intervention group and the other half to the waiting-list control group. Individuals in the intervention group start two-day diagnostics, carried out by a multi-professional rehabilitation team in a rehabilitation center, shortly after the initial consultation. The diagnostics will allow first recommendations for improving work participation. The implementation of these recommendations is supported by an occupational health physician in four follow-up consultations. The control group will receive the comprehensive two-day diagnostic service and subsequent follow-up consultations six months after the initial consultation. The primary outcome of the randomized controlled trial is self-rated work ability assessed using the Work Ability Score (0 to 10 points) six months after study inclusion. Secondary outcomes include a range of patient-reported outcomes regarding physical and mental health, impairment, and the physical and mental demands of jobs.

Discussion

This randomized controlled trial is designed to test the effects of a new complex intervention involving a comprehensive clarification of intervention needs in order to promote work participation and prevent the worsening of health and work disability.

Social participation of community-dwelling older adults in western China: A latent profile analysis

Objective

Social participation has become a policy framework to address population aging. However, little is known about the social participation of older adults in western China, and extensive, multicenter, regional research is lacking. This research investigated the profiles of social participation of older adults in western China and explored the characteristics and factors influencing social participation.

Method

This cross-sectional study was conducted in 3 provinces (Chongqing, Sichuan, and Inner Mongolia) in western China from March 2021 to December 2021 and included 3,456 participants aged 60 years or older. Social participation was assessed using the Chinese version of the Impact on Participation and Autonomy Questionnaire (IPA). Latent profile analysis (LPA) was performed to extract latent classes of social participation among older adults in western China. The chi-square test and multinomial regression analyses were used to identify differences between these classes.

Results

Three social participation classes were identified by LPA: high social participation (25.2%), moderate social participation (55.1%), and low social participation (19.7%). Being older, having a primary school education level, having mobility or speaking impairment, using assistive devices, and having a chronic disease were highly associated with the low social participation class (P < 0.05). Furthermore, older adults with no dependence (OR = 0.018, 95% CI = 0.005-0.062) or mild dependence (OR = 0.039, 95% CI = 0.011-0.139) in activities of daily living (ADLs) were less likely to be in the low social participation class. Older adults who were cared for by non-spouse primary caregivers were more likely to be assigned to the moderate social participation group (OR = 2.097, 95% CI = 1.501-2.930) than to the high social participation group.

Conclusions

Most older adults in western China have a moderate level of social participation. Advanced age, reduced ADL ability, reduced speech ability, reduced mobility, and non-spouse care are related to the level of social participation. Healthcare professionals should pay attention to the predictors for different classes, identifying high-risk groups as early as possible.

Reimagining Prosthetic Control: A Novel Body-Powered Prosthetic System for Simultaneous Control and Actuation

Globally, the most popular upper-limb prostheses are powered by the human body. For body-powered (BP) upper-limb prostheses, control is provided by changing the tension of (Bowden) cables to open or close the terminal device. This technology has been around for centuries, and very few BP alternatives have been presented since. This paper introduces a new BP paradigm that can overcome certain limitations of the current cabled systems, such as a restricted operation space and user discomfort caused by the harness to which the cables are attached. A new breathing-powered system is introduced to give the user full control of the hand motion anywhere in space. Users can regulate their breathing, and this controllable airflow is then used to power a small Tesla turbine that can accurately control the prosthetic finger movements. The breathing-powered device provides a novel prosthetic option that can be used without limiting any of the user’s body movements. Here we prove that it is feasible to produce a functional breathing-powered prosthetic hand and show the models behind it along with a preliminary demonstration. This work creates a step-change in the potential BP options available to patients in the future.

Wheelchair Tai Chi Ball Exercise for Improving Neuromuscular Functions of Older Adults With Disability

The purposes of this perspective article were to summarize Wheelchair or Seated Tai Chi studies related to neuromuscular functions of older adults with disability; to describe the development of Wheelchair Tai Chi Ball (WTCB) exercise — a concept to combine mind-body exercise with strength training; and to propose a new Telehealth WTCB exercise for improving neuromuscular functions of old adults with spinal cord injury (SCI) and disability. With reference to neuromuscular functions, WTC intervention may have positive effects on simple reaction time, range of motion at the shoulder and trunk, static and dynamic sitting balance, handgrip strength, vagal activity, and sympathetic activity among older adults with disability. The developed WTCB intervention is a feasible and safe exercise which combines the mind-body exercise and strength conditioning into one exercise which possesses aerobic, stretching and strength trainings and may facilitate neuromuscular functions of older adults with disability. The proposed Telehealth WTCB 12 forms (TWTCB12) exercise with a “Moving Shadow” method in the telehealth may enable the learner to superimpose learner’s image on an expert’s demonstrating model to enhance the learning and practice effects. Since wheelchair users will learn and practice TWTCB12 movements in a seated position or sitting on a wheelchair the “Moving shadow” method on Zoom would provide an ideal telehealth learning and practice environment for the wheelchair users to learn and practice TWTCB12 exercise from home more feasible and user friendly.

An innovative case management intervention for people at high risk of permanent work disability to improve rehabilitation coverage and coordination of health services: a randomized controlled trial (AktiFAME, DRKS00024648)

BACKGROUND

German social law offers services from various providers and agencies for people with chronic disease or disability. Claiming services requires a high level of information and communication. Dealing with a multitude of actors, such as pension insurance agencies, job centers, employers, physicians, and psychotherapists, and coordinating between and with these actors can delay or prevent the utilization of necessary measures like medical or vocational rehabilitation. We developed a case management intervention for people at high risk of receiving a disability pension to address these challenges.

METHODS/DESIGN

Our randomized controlled trial tests the effectiveness of the multi-component AktiFAME strategy (Active access, counseling, and case management for people at high risk of permanent work disability). This strategy is comprised of four modules: screening and postal contact, telephone counseling, an initial one-on-one interview, and case management. The randomized controlled trial is complemented by an observational study that exclusively involves the individuals participating in case management and accompanies the implementation of the case management intervention. We enroll 9000 individuals aged 18 to 65 years who were identified as being at increased risk for receiving a disability pension based on administrative data from the German Pension Insurance North but who have not yet applied for rehabilitation. Half of the individuals are randomly assigned to the intervention group and the other half to the control group. The intervention group is contacted and informed about a case management intervention, whereas the control group is not. The primary outcome of the randomized controlled trial is the utilization of rehabilitation services from the German Pension Insurance North (medical or vocational rehabilitation). Data on rehabilitation will be provided by the German Pension Insurance North 1 year after random allocation. Secondary and tertiary outcomes cover additional administrative data (e.g., employment and welfare benefits) and a range of patient-reported outcome measures.

DISCUSSION

This randomized controlled trial is designed to determine the effectiveness of a newly implemented multi-component strategy to promote participation and rehabilitation coverage among individuals at high risk of receiving a disability pension.

The unmet need for treatment of children with musculoskeletal impairment in Malawi

Background

More than a billion people globally are living with disability and the prevalence is likely to increase rapidly in the coming years in low- and middle-income countries (LMICs). The vast majority of those living with disability are children residing in LMICs. There is very little reliable data on the epidemiology of musculoskeletal impairments (MSIs) in children and even less is available for Malawi. Previous studies in Malawi on childhood disability and the impact of musculoskeletal impairment (MSI) on the lives of children have been done but on a small scale and have not used disability measurement tools designed for children. Therefore in this study, we aimed to estimate the MSI prevalence, causes, and the treatment need among children aged 16 years or less in Malawi.

Methods

This study was carried out as a national cross sectional survey. Clusters were selected across the whole country through probability proportional to size sampling with an urban/rural and demographic split that matched the national distribution of the population. Clusters were distributed around all 27-mainland districts of Malawi. Population of Malawi was 18.3 million from 2018 estimates, based on age categories we estimated that about 8.9 million were 16 years and younger. MSI diagnosis from our randomized sample was extrapolated to the population of Malawi, confidence limits was calculated using normal approximation.

Results

Of 3792 children aged 16 or less who were enumerated, 3648 (96.2%) were examined and 236 were confirmed to have MSI, giving a prevalence of MSI of 6.5% (CI 5.7–7.3). Extrapolated to the Malawian population this means as many as 576,000 (95% CI 505,000-647,000) children could be living with MSI in Malawi. Overall, 46% of MSIs were due to congenital causes, 34% were neurological in origin, 8.4% were due to trauma, 7.8% were acquired non-traumatic non-infective causes, and 3.4% were due to infection. We estimated a total number of 112,000 (80,000-145,000) children in need of Prostheses and Orthoses (P&O), 42,000 (22,000-61,000) in need of mobility aids (including 37,000 wheel chairs), 73,000 (47,000-99,000) in need of medication, 59,000 (35,000-82,000) in need of physical therapy, and 20,000 (6000-33,000) children in need of orthopaedic surgery. Low parents’ educational level was one factor associated with an increased risk of MSI.

Conclusion

This survey has uncovered a large burden of MSI among children aged 16 and under in Malawi. The burden of musculoskeletal impairment in Malawi is mostly unattended, revealing a need to scale up both P&O services, physical & occupational therapy, and surgical services in the country.

Risk factors for hospital acquired pressure injury in patients with spinal cord injury during first rehabilitation: prospective cohort study

STUDY DESIGN

Prospective observational cohort study.

OBJECTIVES

First, describe pressure injury (PI) and associated risk factors in individuals with spinal cord injury/disorder (SCI/D) during first rehabilitation. Second, evaluate a prediction model for hospital acquired PI (HAPI) development.

SETTING

Acute care and rehabilitation clinic specialized in SCI/D.

METHODS

Patients ≥18 years of age with SCI/D were included during first rehabilitation between 08/2018 and 12/2019. We performed a systematic literature search to identify risk factors for PI development. Patients were classified according to HAPI developed. Between group differences of patients' characteristics and risk factors were analyzed using descriptive statistics. Logistic predictive models were performed to estimate HAPI development and receiver operator characteristic (ROC) curve was used to test the model.

RESULTS

In total, 94 patients were included, 48 (51.1%) developed at least one HAPI and in total 93 were observed, mainly stage I and stage II HAPI according to the European Pressure Ulcer Advisory Panel. We found nine significantly associated risk factors: completeness of SCI/D, pneumonia, sedative medications, autonomic dysreflexia, Braden ≤12 points, SCIPUS ≥9 points, lower admission SCIM and lower admission FIM-cognition, longer length of stay (LOS) (p ≤ 0.0005). In a predictive model, none of the risk factors was associated with HAPI development (AUC = 0.5).

CONCLUSION

HAPIs in patients with SCI/D during first rehabilitation are a frequent and complex condition and associated with several risk factors. No predictive model exists but with the identified risk factors of this study, larger studies can create a tailored and flexible HAPI risk prediction model.

The Effectiveness of Active Rehabilitation Camp on Physical Performance of Disabled People Moving in Wheelchairs

(1) Background: Regular participation in physical activity (PA) prevents many medical complications and improves the physical fitness of people with spinal cord injury, and in turn improves the functional independence, psychosocial status and quality of life. The goal of Active Rehabilitation Camps (ARCs) is to use various forms of PA in order for the participants to obtain the greatest efficiency and independence in everyday life. (2) Purpose: To evaluate the improvement in physical performance of people with chronic spinal cord disabilities moving in wheelchairs taking part in the Active Rehabilitation Camp depending on (a) sex, (b) type of disability, (c) the level of injury and (d) the type of wheelchair. (3) Methods: The study included 42 wheelchair users: 28 men and 14 women aged 18-65 years (34.7 ± 14.9 years) taking part in the Active Rehabilitation Camp. Finally, the study involved 27 paraplegics, 9 tetraplegics and 6 individuals with myelomeningocele. The participants took part in four fitness tests: (1) sprint test (SP)-individual time to cover a distance of 15 m in the wheelchair; (2) slalom test (SL)-time to ride between four cones front and back; (3) basketball ball throw at a distance (BT), (4) zig-zag test (ZZ)-riding continuously for 6 min on the designated track. The tests were performed at the beginning and at the end of the ACR. Active wheelchairs were used by 32 participants, and 10 participants used the classic wheelchairs. (4) Results: Paraplegics achieved the best average results in all the tests and the best improvement in physical performance in comparison to individuals with myelomeningocele and tetraplegics. People in active wheelchairs achieved a statistically significant improvement in the results of SL and ZZ (p < 0.001). People with injury above Th-9 level of the spinal cord achieved a statistically significant improvement in the results of SP (p < 0.01), SL and ZZ (p < 0.01). People with injury below Th6 achieved a statistically significant improvement (p < 0.05) in SP, SL and ZZ. (5) Conclusions: Regular PA during the Active Rehabilitation Camp improves the physical performance of disabled people in wheelchairs, but the scale of improvement of physical performance fitness depends on the type of wheelchair used and the level and the type of injury.

Supporting government policies to embed and expand rehabilitation in health systems in Europe: A framework for action

Investment in action is vital to confront the challenges associated with chronic diseases and disability facing European health systems. Although relevant policy responses are being increasingly developed, most of them fail to recognize the role of rehabilitation services in achieving public health and social goals. Comprehensive guidance is thus urgently needed to support rehabilitation policy development and expand access to rehabilitation care to meet population needs effectively. This paper describes a framework to guide policy action for rehabilitation in Europe. The framework was developed in collaboration with the European Academy of Rehabilitation Medicine based on a focused literature review and expert consultations. A review in PubMed and grey literature sources identified 458 references and resulted in 135 relevant documents published between 2006 and 2019. Thematic analysis of extracted information helped summarize the findings and develop the draft policy action framework. This was circulated to a wider group of experts and discussed in three workshops in 2018-2019. The framework was revised according to their feedback. The proposed framework contains 48 options for policy action organized in six domains and twelve subdomains that address several areas of health programming. The proposed framework provides a structure to understand the policy terrain related to rehabilitation in Europe and the measures required for translating aspirational political pronouncements into targeted programmatic action and tangible health and social outcomes.

A systematic review of the psychometric properties of the Jebsen-Taylor Hand Function Test (JTHFT)

This systematic review of the literature aimed to identify studies examining the psychometric properties of the Jebsen-Taylor Hand Function Test (JTHFT) in various international populations on. The search was conducted in MEDLINE, SCOPUS, CINAHL and Web Of Science, with no restrictions on publication period, the country in which the study was conducted, or the age of the patients. Eligible studies were selected on the basis of inclusion criteria and data were extracted. Study quality and the risk of bias were assessed using the COnsensus-based Standards to select the health Measurement Instruments (COSMIN) checklist. 805 articles were identified; after removing duplicates, there were 361 single studies. 338 articles did not concern the psychometric properties of JTHFT. The remaining 23 studies were selected for full text review, and all were included. They comprised 8 languages and 9 pathologies. These findings suggest the JTHFT is a useful test of manual dexterity in activities of daily living. This study provides specific information on the instrument's psychometric properties in different populations and supports clinicians in making informed decisions when choosing instruments for upper-limb evaluations.

Causal variation modelling identifies large inter- and intra-regional disparities in physical therapy offered to hip fracture patients in Estonia

PURPOSE

An essential measure of hip fracture (HF) rehabilitation, the amount of physical therapy (PT) used per patient, has been severely understudied. This study (1) evaluates post-acute PT use after HF in Estonia, (2) presents causal variation modelling for examining inter- and intra-regional disparities, and (3) analyses its temporal trends.

MATERIALS AND METHODS

This retrospective cohort study used validated population-wide health data, including patients aged ≥50 years, with an index HF diagnosed between January 2009 and September 2017. Patients' 6-month PT use was analysed and reported separately for acute and post-acute phases.

RESULTS

While most of the included 11,461 patients received acute rehabilitation, only 40% of them received post-acute PT by a median of 6 h. Analyses based on measures of central tendency revealed 2.5 to 2.6-fold inter-regional differences in HF post-acute rehabilitation. Variation modelling additionally detected intra-regional disparities, showing imbalances in the fairness of allocating local rehabilitation resources between a county's patients.

CONCLUSIONS

This study demonstrates the advantages of causal variation modelling for identifying inter- and intra-regional disparities in rehabilitation. The analyses revealed persisting large multi-level disparities and accompanying overall inaccessibility of PT in HF rehabilitation in Estonia, showing an urgent need for system-wide improvements.Implications for rehabilitationThis study demonstrates the advantages of causal variation modelling for identifying inter- and intra-regional disparities in rehabilitation, using an essential outcome measure - used physical therapy hours.The study revealed large multi-level disparities and overall inaccessibility of physical therapy in hip fracture rehabilitation in Estonia, showing an urgent need for system-wide improvements.This study expands our knowledge on unstudied topics - hip fracture post-acute care and long-term physical therapy use.This regional analysis provides the first evidence-based regional-level basis for improving the rehabilitation system in Estonia.

A Machine Learning Strategy for Locomotion Classification and Parameter Estimation Using Fusion of Wearable Sensors

The accurate classification of ambulation modes and estimation of walking parameters is a challenging problem that is key to many applications. Knowledge of the user's state can enable rehabilitative devices to adapt to changing conditions, while in a clinical setting it can provide physicians with more detailed patient activity information. This study describes the development and optimization process of a combined locomotion mode classifier and environmental parameter estimator using machine learning and wearable sensors. A detailed analysis of the best sensor types and placements for each problem is also presented to provide device designers with information on which sensors to prioritize for their application. For this study, 15 able-bodied subjects were unilaterally instrumented with inertial measurement unit, goniometer, and electromyography sensors and data were collected for extensive ranges of level-ground, ramp, and stair walking conditions. The proposed system classifies steady state ambulation modes with 99% accuracy and ambulation mode transitions with 96% accuracy, along with estimating ramp incline within 1.25 degrees, stair height within 1.29 centimeters, and walking speed within 0.04 meters per second. Mechanical sensors (inertial measurement units, goniometers) are found to be most important for classification, while goniometers dominate ramp incline and stair height estimation, and speed estimation is performed largely with a single inertial measurement unit. The feature tables and Matlab code to replicate the study are published as supplemental materials.

The effects of sitting Tai Chi on physical and psychosocial health outcomes among individuals with impaired physical mobility: A systematic review and meta-analysis

BACKGROUND

Impaired physical mobility refers to a limitation in independent and purposeful physical movement of the body or one or more extremities. Physical restrictions result in negative consequences on an individual's physical and psychosocial functions. Sitting Tai Chi, a derivative form of traditional Tai Chi, has been found to increase the flexibility of all joints involved and enhance the ability to perform physical activity. However, the evidence of sitting Tai Chi on physical and psychosocial health outcomes on individuals with impaired physical mobility is limited.

OBJECTIVES

To critically synthesize evidence that evaluates the effects of sitting Tai Chi on health outcomes among individuals with impaired physical mobility and to identify implementation strategies for the sitting Tai Chi intervention.

METHODS

Searches were performed across 11 English and two Chinese databases systematically from inception to January 2020. Randomised controlled trials and non-randomised controlled trials, written in English or Chinese were included. Two independent reviewers screened all eligible studies, appraised risk of bias, and extracted the data. Meta-analyses were conducted using Review Manager 5.4 and narrative syntheses were performed where meta-analysis was inappropriate. The certainty of evidence was assessed using Grades of Recommendation, Assessment, Development and Evaluation profiler Guideline Development Tool. This study was registered in PROSPERO.

RESULTS

A total of 1,446 records were generated and 11 studies were eligible for inclusion. Meta-analysis reported a statistically significant effect size favouring sitting Tai Chi on depressive symptoms (SMD: -1.53, 95% CI: -2.81 to -0.21, 2 studies; very low quality), heart rate (MD: -5.72, 95% CI: -11.16 to -0.29, 2 studies; low quality) and social domain of quality of life (MD: 1.42, 95% CI: 0.66 to 2.19, 3 studies; low quality).

CONCLUSIONS

Sitting Tai Chi was found to have favourable effects on depressive symptoms, heart rate, and social domain of quality of life of individuals with impaired physical mobility. Very low to low quality evidence does not support the effectiveness of sitting Tai Chi on dynamic sitting balance, handgrip strength, and the physical and psychological domains of quality of life. There was limited evidence to suggest the best implementation strategies for the sitting Tai Chi intervention. It is anticipated that more well-designed studies will continue developing high quality evidence in this field.

Human Hand Anatomy-Based Prosthetic Hand

The present paper describes the development of a prosthetic hand based on human hand anatomy. The hand phalanges are printed with 3D printing with Polylactic Acid material. One of the main contributions is the investigation on the prosthetic hand joins; the proposed design enables one to create personalized joins that provide the prosthetic hand a high level of movement by increasing the degrees of freedom of the fingers. Moreover, the driven wire tendons show a progressive grasping movement, being the friction of the tendons with the phalanges very low. Another important point is the use of force sensitive resistors (FSR) for simulating the hand touch pressure. These are used for the grasping stop simulating touch pressure of the fingers. Surface Electromyogram (EMG) sensors allow the user to control the prosthetic hand-grasping start. Their use may provide the prosthetic hand the possibility of the classification of the hand movements. The practical results included in the paper prove the importance of the soft joins for the object manipulation and to get adapted to the object surface. Finally, the force sensitive sensors allow the prosthesis to actuate more naturally by adding conditions and classifications to the Electromyogram sensor.

The effects of sitting Tai Chi on physical and psychosocial health outcomes among individuals with impaired physical mobility

BACKGROUND

Impaired physical mobility, most often seen in people with neurological disorders (i.e., stroke and spinal cord injury survivors), musculoskeletal diseases or frailty, is a limitation in independent and purposeful physical movement of the body or one or more extremities. The physical restrictions result in negative consequences on an individual's physical and psychosocial functions. This proposal describes a systematic review protocol to determine the effectiveness and approaches of sitting Tai Chi intervention for individuals with impaired physical mobility. Our review would inform stakeholders' decisions in integrating this complementary therapy into current rehabilitation services.

METHODS

Randomized controlled trials or quasi-experimental studies that compared an intervention group receiving sitting Tai Chi with a control group among adult participants with impaired physical mobility resulting from any health condition(s) will be included. Outcomes of interest will include physical and psychosocial health outcomes. The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, PubMed, CINAHL, Scopus, Web of Science, AMED, PsycINFO, SPORDiscus, PEDro, WanFang Data and China National Knowledge Infrastructure will be searched from their inception to January 2020. Additional searches will be performed to identify studies that are being refereed, to be published, unpublished or ongoing. Two reviewers will select the trials and extract data independently. The risk of bias of the included studies will be assessed using the Cochrane risk-of-bias tools. The Grading of Recommendations, Assessment, Development and Evaluation will be used to assess evidence quality for each review outcome. Data synthesis will be performed using Review Manager 5.3. When a meta-analysis is possible, we will assess the heterogeneity across the studies by computing the I statistics.

RESULTS

A high-quality synthesis of current evidence of sitting Tai Chi for impaired physical mobility will be stated from several aspect using subjective reports and objective measures of performance.

CONCLUSION

This protocol will present the evidence of whether sitting Tai Chi is an effective intervention for impaired physical mobility.

Toward an optimization of rehabilitation services for persons with spinal cord injury in Mongolia: the perspective of medical doctors

PURPOSE

To explore medical doctors' views on what are barriers in providing rehabilitation services for persons with SCI in Mongolia.

METHODS

A qualitative study with semi-structured interviews was conducted with 12 medical doctors. Participants were purposely sampled. The World Health Organization (WHO)'s report International Perspectives on Spinal Cord Injury was chosen as a guide to structure the interviews. The study used inductive thematic analysis.

RESULTS

Five barriers in the provision of rehabilitation services were identified: low awareness and limited knowledge regarding SCI and rehabilitation issues, inadequate rehabilitation policies, deficiencies in infrastructure, deficiencies in equipment and medication, and a shortage of well-prepared rehabilitation workforce.

CONCLUSIONS

Based on WHO recommendations "Rehabilitation in health systems", this study provides suggestions on how to strengthen rehabilitation services in Mongolia to better respond to the needs of the SCI population. Our findings highlight that a core issue is the lack of awareness among policymakers regarding rehabilitation and its benefits at the micro, meso and macro levels of the health system. Actions are needed at the level of health policies to ensure, for instance, adequate financing and access to the services. Also, synergies between the Ministries of Education and Health can improve the training of the workforce.Implications for rehabilitationEvidence that rehabilitation services contribute to improving health outcomes and cost-effectiveness could raise awareness among Mongolian policymakers and inform their decisions on funding schemes.Health policies in Mongolia should be reformed to remove barriers in the provision of rehabilitation services for persons with complex and chronic health conditions.Rehabilitation services need to be included into the Mongolian health insurance scheme in order to improve the quality and accessibility of rehabilitation services.Synergies between the Ministry of Education and the Ministry of Health in Mongolia are needed to develop training standards for rehabilitation professionals.

Design and Analysis of Flexible Joints for a Robust 3D Printed Prosthetic Hand

In war-affected regions in the world, limb loss is one of the leading injuries. The need for low-cost, low-maintenance prostheses arises. The rapid developments in 3D printing allows us to investigate robotic or prosthetic hand designs that can satisfy those basic requirements. 3D printed prosthetic hands are more affordable and lightweight alternatives for prostheses. In this paper, we investigate the flexibility of different designs of the soft joints of a low-cost 3D printed prosthetic hand with respect to the material type. We designed flexible joints from elastomeric materials instead of plastic joints. This modification can make the current 3D printed prosthesis designs more robust. As a drawback from these flexible joints, the prosthetic hand will not be in a full open palm position in its initial state, as compared to typical designs. We then converted this drawback to a beneficial feature by calculating the angles of the natural pose of the human hands and transfer those angles to the prosthetic hands with flexible joints. This work has implications in the design of 3D printed prosthetic hands that can be deployed for war-wounded refugees or for those in low-resource countries.

Development and psychometric properties of the physical rehabilitation services acceptability questionnaire

Background: Access to rehabilitation services is considered to be a right for all people. One of the most important indicators for access to rehabilitation services is an individual's general acceptance of rehabilitation. This tool was designed based on relevant studies and experiences of rehabilitation specialists to design a questionnaire to specifically measure patient acceptability of physical rehabilitation services. Methods: In this study, an exploratory sequential mixed methods design was used. The first phase included a review of the literature and analysis of relevant studies, focus group discussions, and qualitative content analysis. In the second phase, construct validity was assessed by exploratory and confirmatory factor analysis. Also, convergent and divergent validity were measured. Reliability was evaluated by internal consistency (Cronbach's alpha and McDonald's Omega) and construct reliability. Statistical procedures were calculated by SPSS-AMOS24 and JASP0.9.2 software. Results: A total of 200 questionnaires were completed by members of Iranian Disability Campaign. Three factors and 25 items were identified according to results of the first phase of this study. In the second phase, face validity was confirmed. To assess the content validity ratio, 9 items, with the mean of content validity ratio (CVR) < 0.49, were deleted, while the content validity index (CVI) < 0.79 was revised. The kappa coefficient < 0.6 was fair and scale content validity index (SCVI) under 0.9 was considered appropriate. Results of exploratory factor analysis showed that 48% of the variance of the acceptability of physical rehabilitation services was based on patients' satisfaction, ethical behavior, and patient centered services. Confirmatory factor analysis confirmed the suitability of the final model. Convergent and divergent validity and reliability of the measure, the Physical Rehabilitation Services Acceptability questionnaire was fulfilled. Conclusion: Findings indicated that the proposed constructs that promoted the Acceptability of Physical Rehabilitation Services Questionnaire had good validity and reliability in participants with physical disabilities.

Availability of outpatient rehabilitation facilities in 2015 in Iran: A nationwide study

Background: Disability can involve many by diseases, injuries, or aging, and thus access to rehabilitation services has a key role in improving these patients' social life. Since 2008, Iran has improved the access to rehabilitation facilities along with the global convention. Yet, nationwide studies are required to evaluate the fair distribution of centres in each province. Thus, the present study aimed to evaluate the distribution of outpatient rehabilitation services in 32 provinces of Iran to help policymakers make more appropriate decisions. Methods: In this cross sectional study, which was conducted between April and October 2017, a master facilities list (MFL) of rehabilitation services that was developed in Iran was used to identify health facilities. Data were collected from the statistics of the Deputy for Rehabilitation of Social Welfare Organization offices and Red Crescent Organization in 32 provinces of Iran. Descriptive data were analysed by SPSS version 22 and reported by percentage and number in 1 000 000 population; distribution was drawn on Iran's map by the GIS software. Results: According to the MFL, outpatient rehabilitation services include physical medicine & rehabilitation, physiotherapy, occupational therapy, speech therapy, audiometry, and orthotics & prosthetics (90%); other rehabilitation centres include general rehabilitation centres, day care centres, and vocational centres (10%). The largest number of occupational therapy, physiotherapy, and audiology offices were found in Tehran, where general rehabilitation centres, day care centres, and vocational centres were less than 3 per 1 000 000 population. There were no rehabilitation centers in 14 provinces, and there were very few physical medicine and rehabilitation centres in most of the provinces. Conclusion: There was significant difference in the distribution of outpatient rehabilitation facilities in different provinces of Iran and some provinces required urgent attention of policymakers, as they had the least number or no rehabilitation facilities.

[Rehabilitation and work participation]

Work participation is increasingly seen as a primary outcome of rehabilitation measures. Randomised controlled trials from several different countries and the reviews and meta-analyses based on them show that multidisciplinary rehabilitation programmes improve work participation, return-to-work rates, and reduce sickness absence in patients with back pain, depression, and cancer. In Germany, such programmes were implemented as work-related medical rehabilitation. This intervention targets patients with poor work ability and an increased risk of permanent work disability. Randomised controlled trials have confirmed a reduction of sickness absence and increased rates of sustainable work participation in favour of work-related medical rehabilitation as compared to common medical rehabilitation. Dissemination of these programmes and translation of research evidence into practice progresses. An additional important strategy to support returning to work following rehabilitation is graded return to work. There is emerging evidence of sustainable employment effects in favour of graded return to work. A direct involvement of the workplace and a closer cooperation with employers and occupational health physicians may further improve the outcomes of rehabilitation programmes. Strategies that synergistically integrate safety, health promotion and rehabilitation may achieve more favourable outcomes than separated actions.

The development of a low-cost three-dimensional printed shoulder, arm, and hand prostheses for children

BACKGROUND AND AIM

The prosthetic options for higher level amputees are limited and costly. Advancements in computer-aided design programs and three-dimensional printing offer the possibility of designing and manufacturing transitional prostheses at very low cost. The aim of this project was to describe an inexpensive three-dimensional printed mechanical shoulder prosthesis to assist a pre-selected subject in performing bi-manual activities.

TECHNIQUE

The main function of the body-powered, manually adjusted three-dimensional printed shoulder prosthesis is to provide a cost-effective, highly customized transitional device to individuals with congenital or acquired forequarter amputations.

DISCUSSION

After testing the prototype on a young research participant, a partial correction of the patient's spinal deviation was noted due to the counterweight of the device. The patient's family also reported improved balance and performance of some bimanual activities after 2 weeks of using the device. Limitations of the design include low grip strength and low durability. Clinical relevance The prosthetic options for higher level amputees are limited and costly. The low-cost three-dimensional printed shoulder prosthesis described in this study can be used as a transitional device in preparation for a more sophisticated shoulder prosthesis.

The One or the Many: Quantified Subjectivity and Aggregated Uniqueness in Qualitative Rehabilitation Research

This article aims to identify and critically assess qualitative intervention studies of rehabilitation processes that target young adults. By applying a meta-epistemological approach inspired by the works of Michel Foucault and Julia Kristeva, we examine how the included studies present qualitative knowledge and whether they adhere to their own stated principles of qualitative knowledge. Through their stated aims and theoretical framing, the articles draw attention to individual processes of meaning making. Nonetheless, we find that the articles to a great extent emphasize frequencies of the qualitative data they present. Individual processes and experiences are subject to subdivisions and categorization and transformed into manageable objects of knowledge. In conclusion, these studies, with one important exception, contribute to self-marginalization of the knowledge they themselves promote: They undermine the uniqueness of the qualitative knowledge they proclaim by focusing on frequency and the general patterns and categories encompassing the unique.

Cyborg beast: a low-cost 3d-printed prosthetic hand for children with upper-limb differences

BACKGROUND

There is an increasing number of children with traumatic and congenital hand amputations or reductions. Children's prosthetic needs are complex due to their small size, constant growth, and psychosocial development. Families' financial resources play a crucial role in the prescription of prostheses for their children, especially when private insurance and public funding are insufficient. Electric-powered (i.e., myoelectric) and body-powered (i.e., mechanical) devices have been developed to accommodate children's needs, but the cost of maintenance and replacement represents an obstacle for many families. Due to the complexity and high cost of these prosthetic hands, they are not accessible to children from low-income, uninsured families or to children from developing countries. Advancements in computer-aided design (CAD) programs, additive manufacturing, and image editing software offer the possibility of designing, printing, and fitting prosthetic hands devices at a distance and at very low cost. The purpose of this preliminary investigation was to describe a low-cost three-dimensional (3D)-printed prosthetic hand for children with upper-limb reductions and to propose a prosthesis fitting methodology that can be performed at a distance.

RESULTS

No significant mean differences were found between the anthropometric and range of motion measurements taken directly from the upper limbs of subjects versus those extracted from photographs. The Bland and Altman plots show no major bias and narrow limits of agreements for lengths and widths and small bias and wider limits of agreements for the range of motion measurements. The main finding of the survey was that our prosthetic device may have a significant potential to positively impact quality of life and daily usage, and can be incorporated in several activities at home and in school.

CONCLUSIONS

This investigation describes a low-cost 3D-printed prosthetic hand for children and proposes a distance fitting procedure. The Cyborg Beast prosthetic hand and the proposed distance-fitting procedures may represent a possible low-cost alternative for children in developing countries and those who have limited access to health care providers. Further studies should examine the functionality, validity, durability, benefits, and rejection rate of this type of low-cost 3D-printed prosthetic device.

Implementing a system to evaluate quality assurance in rehabilitation in Greece

BACKGROUND

Use of a widely accepted quality assurance tool is an essential procedure of effective and result-oriented quality management in the rehabilitation sector, and generally in health care and social services, but is still lacking in Greece.

OBJECTIVE

This study aims to explore to what extent a Quality Assurance System in Rehabilitation (QASR) in the Greek setting could respond to the needs for quality evaluation of the facilities for people with a disability and to discuss possibilities of its use in rehabilitation organizations, sites and hospitals.

METHODS

The European Quality in Social Services (EQUASS) Assurance self-assessment questionnaire was officially translated and used as the basis for the new tool, which consisted of 110 questions in 11 sections on development and 6 questions on its evaluation. This tool was tested in 15 specialized centers.

RESULTS

The study received a high (93.75%) response rate. Overall score ranged from 11% to one perfect 100%; 53.3% of the facilities fell short of the preset qualification standards, while 4 (26.7%) were qualified for level-1 accreditation. Evaluation of the QASR questionnaire for the function of the rehabilitation facilities for the disabled was extremely positive.

CONCLUSIONS

The EQUASS assurance-based Greek QASR has received proper attention in its first implementation and it was shown promising to assess the needs of sites that would like to improve their services. The next steps are to establish its validity and reliability so that it can significantly emerge as the standard system for guiding policy in the rehabilitation sector in Greece.
