BackgroundHuman resources for rehabilitation are often a neglected component of health services strengthening and health workforce development. This may be partly related to weaknesses in the available research and evidence to inform advocacy and programmatic strategies. The objective of this study was to quantitatively describe the global situation in terms of supply of and need for human resources for health-related rehabilitation services, as a basis for strategy development of the workforce in physical and rehabilitation medicine.MethodsData for assessing supply of and need for rehabilitative personnel were extracted and analyzed from statistical databases maintained by the World Health Organization and other national and international health information sources. Standardized classifications were used to enhance cross-national comparability of findings.ResultsLarge differences were found across countries and regions between assessed need for services requiring health workers associated to physical and rehabilitation medicine against estimated supply of health personnel skilled in rehabilitation services. Despite greater need, low- and middle-income countries tended to report less availability of skilled health personnel, although the strength of the supply-need relationship varied across geographical and economic country groupings.ConclusionThe evidence base on human resources for health-related rehabilitation services remains fragmented, the result of limited availability and use of quality, comparable data and information within and across countries. This assessment offered the first global baseline, intended to catalyze further research that can be translated into evidence to support human resources for rehabilitation policy and practice.

BackgroundPeople with disabilities face challenges accessing basic rehabilitation health care. In 2006, the United Nations Convention on the Rights of Persons with Disabilities (CRPD) outlined the global necessity to meet the rehabilitation needs of people with disabilities, but this goal is often challenged by the undersupply and inequitable distribution of rehabilitation workers. While the aggregate study and monitoring of the physical rehabilitation workforce has been mostly ignored by researchers or policy-makers, this paper aims to present the ‘challenges and opportunities’ for guiding further long-term research and policies on developing the relatively neglected, highly heterogeneous physical rehabilitation workforce.MethodsThe challenges were identified through a two-phased investigation. Phase 1: critical review of the rehabilitation workforce literature, organized by the availability, accessibility, acceptability and quality (AAAQ) framework. Phase 2: integrate reviewed data into a SWOT framework to identify the strengths and opportunities to be maximized and the weaknesses and threats to be overcome.ResultsThe critical review and SWOT analysis have identified the following global situation: (i) needs-based shortages and lack of access to rehabilitation workers, particularly in lower income countries and in rural/remote areas; (ii) deficiencies in the data sources and monitoring structures; and (iii) few exemplary innovations, of both national and international scope, that may help reduce supply-side shortages in underserved areas.DiscussionBased on the results, we have prioritized the following ‘Six Rehab-Workforce Challenges’: (1) monitoring supply requirements: accounting for rehabilitation needs and demand; (2) supply data sources: the need for structural improvements; (3) ensuring the study of a whole rehabilitation workforce (i.e. not focused on single professions), including across service levels; (4) staffing underserved locations: the rising of education, attractiveness and tele-service; (5) adapt policy options to different contexts (e.g. rural vs urban), even within a country; and (6) develop international solutions, within an interdependent world.ConclusionsConcrete examples of feasible local, global and research action toward meeting the Six Rehab-Workforce Challenges are provided. Altogether, these may help advance a policy and research agenda for ensuring that an adequate rehabilitation workforce can meet the current and future rehabilitation health needs.Electronic supplementary materialThe online version of this article (doi:10.1186/s12960-017-0182-7) contains supplementary material, which is available to authorized users.

Segmental body composition assessed by bioelectrical impedance analysis and DEXA in humans. J. Appl. Physiol. 81(6): 2580-2587, 1996.-The present study assessed the relative contribution of each body segment to whole body fat-free mass (FFM) and impedance and explored the use of segmental bioelectrical impedance analysis to estimate segmental tissue composition. Multiple frequencies of whole body and segmental impedances were measured in 51 normal and overweight women. Segmental tissue composition was independently assessed by dual-energy X-ray absorptiometry. The sum of the segmental impedance values corresponded to the whole body value (100.5 6 1.9% at 50 kHz). The arms and legs contributed to 47.6 and 43.0%, respectively, of whole body impedance at 50 kHz, whereas they represented only 10.6 and 34.8% of total FFM, as determined by dual-energy X-ray absorptiometry. The trunk averaged 10.0% of total impedance but represented 48.2% of FFM. For each segment, there was an excellent correlation between the specific impedance index (length 2 /impedance) and FFM (r 5 0.55, 0.62, and 0.64 for arm, trunk, and leg, respectively). The specific resistivity was in a similar range for the limbs (159 6 23 cm for the arm and 193 6 39 cm for the leg at 50 kHz) but was higher for the trunk (457 6 71 cm). This study shows the potential interest of segmental body composition by bioelectrical impedance analysis and provides specific segmental body composition equations for use in normal and overweight women. dual-energy X-ray absorptiometry; body segments; body fat; fat-free mass

Objective: To determine the usefulness of computed tomography (CT), magnetic resonance imaging (MRI), and Doppler ultrasonography (US) in providing specific images of gouty tophi. Methods: Four male patients with chronic gout with tophi affecting the knee joints (three cases) or the olecranon processes of the elbows (one case) were assessed. Crystallographic analyses of the synovial fluid or tissue aspirates of the areas of interest were made with polarising light microscopy, alizarin red staining, and x ray diffraction. CT was performed with a GE scanner, MR imaging was obtained with a 1.5 T Magneton (Siemens), and ultrasonography with colour Doppler was carried out by standard technique. Results: Crystallographic analyses showed monosodium urate (MSU) crystals in the specimens of the four patients; hydroxyapatite and calcium pyrophosphate dihydrate (CPPD) crystals were not found. A diffuse soft tissue thickening was seen on plain radiographs but no calcifications or ossifications of the tophi. CT disclosed lesions containing round and oval opacities, with a mean density of about 160 Hounsfield units (HU). With MRI, lesions were of low to intermediate signal intensity on T 1 and T 2 weighting. After contrast injection in two cases, enhancement of the tophus was seen in one. Colour Doppler US showed the tophi to be hypoechogenic with peripheral increase of the blood flow in three cases. Conclusion: The MR and colour Doppler US images showed the tophi as masses surrounded by a hypervascular area, which cannot be considered as specific for gout. But on CT images, masses of about 160 HU density were clearly seen, which correspond to MSU crystal deposits.I n previous studies we have shown that MSU crystal deposits in chronic gout may be identified by CT in the knee joints, 1 in the tendons, 2 and in subcutaneous tissues. 3 They appear as round and oval opacities having a CT attenuation in the range of 150-200 HU. This study aimed at comparing CT with magnetic resonance MR imaging and PATIENTS AND METHODSFour men with chronic tophaceous gout were examined. Their mean age was 56.3 years and the mean duration of gout 18 years. Associated disorders were hypertension and type II diabetes (patient 1), obesity and gonarthrosis (patient 2), allergy to allopurinol (patient 3), and hypertension (patient 4). Imaging of the left olecranon was carried out in patient 1, the left knee in patient 2, and the prepatellar bursa in patients 3 and 4. Identification of crystalsNeedle aspiration of synovial fluid (patients 2, 3, 4) or tophaceous material (patient 1) was made in the area which was imaged. The aspirates were examined with polarising light microscopy and a first order red filter, then they were coloured with alizarin red stain, according to the technique of Paul et al for detection of apatite.4 The samples were analysed with powder diffraction x ray by standard methods. 5Imaging technique Conventional x ray examinations were made in all the cases. CT examination was performed with a 9800 high speed advantage scanner (GE), MR...

Understanding mothers' perceptions of disability and treatment, and the myriad of factors that influence those perceptions, provides valuable knowledge to assist in planning and delivery of family centered rehabilitation services for CWD. Rehabilitation has a central role to play in assisting mothers' understanding of the nature of their children's disabilities and how they can be managed. Ultimately, such an understanding may translate into improved social and educational opportunities for CWD.

Finding the "right-size" physical therapy workforce is an increasingly important issue, but it has had limited study, particularly across nations. This perspective article provides a comprehensive examination of physical therapy workforce issues across 4 countries (United States, Singapore, Portugal, and Bangladesh), which were deliberately selected to allow consideration of key contextual factors. This investigation provides a theoretical model uniquely adapted to focus on variables most likely to affect physical therapy workforce needs. This theoretical model was used to guide acquisition of public domain data across the respective countries. The data then were used to provide a contextualized interpretation about the physical therapy workforce supply (ie, physical therapists per capita) across the 4 countries in light of the following factors: indicators of physical therapy need, financial and administrative barriers affecting physical therapy access and demand, the proportion of physical therapy graduates (with varying trends over time across the countries), and the role of emigration/immigration in supply inequalities among countries of lower and higher income. In addition, both the physical therapy workforce supply and scope of practice were analyzed in the context of other related professions across the 4 countries. This international comparison indicated that there may not be a "one-size-fits-all" recommendation for physical therapy workforce supply across countries or an ideal formula for its determination. The optimal, country-specific physical therapy workforce supply appears to be affected by discipline-specific health care and contextual factors that may vary across countries, and even within the same country. This article provides a conceptual framework and basis for such contextualized evaluations of the physical therapy workforce.

BACKGROUND: The novel coronavirus (COVID-19) that emerged in late 2019, and later become a global pandemic, has unleashed an almost unprecedented global public health and economic crisis. OBJECTIVE: In this perspective, we examine the effects of COVID-19 and identify a likely ‘new normal’ in terms of challenges and opportunities within the fields of disability, telework, and rehabilitation. METHODS: We use a systems thinking lens informed by recent empirical evidence and peer-reviewed qualitative accounts regarding the pandemic to identify emerging challenges, and pinpoint opportunities related to health and changing employment infrastructure of people with disabilities and rehabilitation professionals. RESULTS: From our interpretation, the key leverage points or opportunities include: (1) developing disability-inclusive public health responses and emergency preparedness; (2) enabling employment and telework opportunities for people with disabilities; (3) addressing the new requirements in rehabilitation service provision, including participating as essential team members in the care of people with infectious diseases such as COVID-19; (4) embracing the added emphasis on, and capacity for, telehealth; and (5) developing greater resilience, distance learning, and employability among the rehabilitation workforce. CONCLUSIONS: The COVID-19 pandemic has become increasingly challenging to the lives of people with disabilities and rehabilitation professionals; however, key challenges can be minimized and opportunities can be capitalized upon in order to ‘build back better’ after COVID-19.

No causal relationships can be inferred using these cross-sectional data. However, results suggest that direct patient contact that includes lifting and/or transferring patients may be an important risk factor. Further research is warranted to evaluate effectiveness of back education and prevention programs among hospital staff in Kuwait.
