This innovation insight discusses current approaches to digital fabrication of lower limb prosthetics (LLP) sockets aimed at low resourced settings. Digital fabrication of LLPs sockets has been researched for a number of decades, yet these technologies are not widely adopted, and most of the activities within this domain reside in high-income settings. However, the majority of amputees are in LMICs where there is a severe lack of access to services. It is in LMICs then, that the advantages that digital technologies offer could be of particular benefit however little to no progress in digital workflow adoption has been made to date.

Purpose: To explore work related and personal facilitators and barriers for return to work (RTW) and stay at work after stroke.

 

Materials and methods: Twenty individuals post-stroke (median age 52 years; seven women) were inter- viewed in focus groups. Data were analyzed by using qualitative content analysis.

 

Results: An overall theme “Work conditions, support and changed personal priorities influenced RTW and stay at work after stroke” emerged and covered three categories: “Adjustments and flexibility at the work place facilitated RTW and a sustainable work situation”, “Psychosocial support and knowledge about stroke consequences facilitated work and reduced stress”, and “Changed view of work and other personal priorities”. Physical adjustments at the work place and flexibility in the work schedule were perceived facilitators. Support from family and colleagues were important, whereas lack of knowledge of stroke dis- abilities at the work place was perceived a barrier. Also changed personal priorities in relation to the work and the current life situation influenced RTW in various ways.

 

Conclusions: The individual’s opportunities to influence the work situation is a key factor for RTW and the ability to stay at work after stroke. Adjustments, flexibility, support, knowledge of stroke, and receptiv- ity to a changed view of work are important for a sustainable work situation.

Purpose

Telehealth provides psychotherapeutic interventions and psychoeducation for remote populations with limited access to in-person behavioural health and/or rehabilitation treatment. The United States Department of Défense and the Veterans Health Administration use telehealth to deliver primary care, medication management, and services including physical, occupational, and speech-language therapies for service members, veterans, and eligible dependents. While creative arts therapies are included in telehealth programming, the existing evidence base focuses on art therapy and dance/movement therapy, with a paucity of information on music therapy.

 

Methods

Discussion of didactic and applied music experiences, clinical, ethical, and technological considerations, and research pertaining to music therapy telehealth addresses this gap through presentation of three case examples. These programmes highlight music therapy telehealth with military-connected populations on a continuum of clinical and community engagement: 1) collaboration between Berklee College of Music in Boston, MA and the Acoke Rural Development Initiative in Lira, Uganda; 2) the Semper Sound Cyber Health programme in San Diego, CA; and 3) the integration of music therapy telehealth into Creative Forces®, an initiative of the National Endowment for the Arts.

 

Results

These examples illustrate that participants were found to positively respond to music therapy and community music engagement through telehealth, and reported decrease in pain, anxiety, and depression; they endorsed that telehealth was not a deterrent to continued music engagement, requested continued music therapy telehealth sessions, and recommended it to their peers.

 

Conclusions

Knowledge gaps and evolving models of creative arts therapies telehealth for military-connected populations are elucidated, with emphasis on clinical and ethical considerations.

Purpose: 

To develop a predictive model to inform the probability of lower limb prosthesis users’ functional potential for ambulation.

 

Materials and Methods: 

A retrospective analysis of a database of outcomes for 2770 lower limb prosthesis users was used to inform a classification and regression tree analysis. Gender, age, height, weight, body mass index adjusted for amputation, amputation level, cause of amputation, comorbid health status and functional mobility score [Prosthetic Limb Users Survey of Mobility (PLUS-M™)] were entered as potential predictive variables. Patient K-Level was used to assign dependent variable status as unlimited community ambulator (i.e., K3 or K4) or limited community/household ambulator (i.e., K1 or K2). The classification tree was initially trained from 20% of the sample and subsequently tested with the remaining sample.

 

Results: 

A classification tree was successfully developed, able to accurately classify 87.4% of individuals within the model’s training group (standard error 1.4%), and 81.6% within the model’s testing group (standard error 0.82%). Age, PLUS-M™ T-score, cause of amputation and body weight were retained within the tree logic.

 

Conclusions: 

The resultant classification tree has the ability to provide members of the clinical care team with predictive probabilities of a patient’s functional potential to help assist care decisions.

Adaptations from the prosthetic and intact limb during standing on a sway-referenced support surface for transtibial prosthesis users

RUSAW, David F

Expand view

Purpose: 

To investigate the bilateral postural adaptations as a result of standing on an increasingly unstable sway-referenced support surface with both the intact and prosthetic limb for transtibial prosthesis users (TPUs).

 

Method: 

TPUs (n = 14) and matched controls (n = 14) stood quietly in multiple foot placement conditions (intact foot, prosthetic foot and both feet) on a sway-referenced support surface which matched surface rotation to the movement of the centre of pressure (CoP). Force and motion data were collected and used to analyse CoP mean position, displacement integral and force components under intact and prosthetic limbs.

 

Results: 

Significant differences were found between prosthesis users and controls in CoP mean position in anteroposterior (1.5 (95% CI, 1.2–1.8) cm) and mediolateral directions (3.1 (95% CI, 0.5–5.7) cm. CoP displacement integrals were significantly different greater for prosthesis user group in the anteroposterior direction. Force components differences were found in all planes (anteroposterior: 0.6 (95% CI, 0.4–0.8 N); mediolateral: 0.1 (95% CI, 0.0–0.2 N & 0.3 (95% CI, 0.2–0.4) N, inferosuperior: 2.2 (95% CI, 1.4–3.0) N).

 

Conclusions: 

TPUs have bilateral static and dynamic postural adaptations when standing on a sway-referenced support surface that is different to controls, and between prosthetic and intact sides. Results further support evidence highlighting importance of the intact limb in maintenance of postural control in prosthesis users. Differences indicate clinical treatment should be directed towards improving outcomes on the intact side.

Purpose: This study aims to identify the most important factors that influence the independent bicycle use of visually impaired people in the Netherlands.

 

Materials and methods: Both visually impaired people and professionals participated in a two-round online Delphi study (n = 42). In Round 1 the participants identified the factors which they ranked by relevance in Round 2.

 

Results: The participants prioritised environmental factors related to the traffic situation, the characteristics of the infrastructure, and weather and light conditions (Kendall’s W = 0.66). They indicated that the most influencing personal factors are related to personality, traffic experience, and personal background (W = 0.58). Glaucoma was ranked as the most relevant ophthalmic condition (W = 0.74), while glare was regarded as the most important factor with respect to the visual functions (W = 0.78).

 

Conclusions: The factors provided by this study can be used to optimise the independent cycling mobility of visually impaired people. More research is needed to investigate, both, how and to what extent the mentioned factors influence the cycling behaviour.

Purpose: Social inclusion of children with physical disabilities is essential for their mental health. The long-standing conflict and political instability in Palestine since 1948 has resulted in an unprecedented number of children with disabilities. This study aimed to assess social inclusion and mental health of children with physical disabilities in Palestine.

 

Method: A mixed methods research design was used. The 12-item General Health Questionnaire and a Social Inclusion Questionnaire were administered to 100 children with amputations, 12-18 years of age, in the Gaza Strip. Ten semi-structured interviews were also conducted with personnel working across civil society rehabilitation services in the area, particularly in services that focussed on the physical rehabilitation of children who had lost a limb.

 

Results: Quantitative findings indicated that 88% of children’s disabilities were caused by war-related incidents. While the sample of children showed on average relatively low levels of psychological distress, males reported feeling more socially included and having better mental health than did females. Furthermore, there was a strong positive correlation between mental health and social inclusion, and a moderate positive correlation between psychological distress and social inclusion. The qualitative data identified different factors that hinder social inclusion, mainly: political instability; under-resourced disability organisations; lack of coordinated efforts; and negative societal attitudes towards disability.

 

Conclusion: A new questionnaire for social inclusion was developed, which can now be used as a tool to assess social inclusion in similar contexts; as well as a culturally-adapted form of the General Health Questionnaire-12 to assess mental health. There is a clear need for service-providers to move beyond a medical model of care to one that embraces community-based rehabilitation and the realisation of rights, in order to promote the social inclusion and mental health of children with disabilities in Palestinian society.

Background: There is an urgent global need to strengthen rehabilitation services for people with disabilities. In sub-Saharan Africa, rehabilitation services for people with communication disabilities continue to be underdeveloped. A first step in strengthening services for people with a communication disabilities is to understand the composition and conditions of the current workforce.


Objectives: This research describes a sample of the speech and language therapists (SLTs) working in SSA (excluding South Africa). This study explores the characteristics of this workforce, including their demographics, education, experience and geographical stability.


Method: A mixed-methods survey was used to collect data from SLTs within Anglophone countries of SSA. Completed surveys were received from 33 respondents working in 44 jobs across nine countries. Analysis included descriptive and non-parametric inferential statistics. This study reports on a subset of descriptive and quantitative data from the wider survey.


Results: A background profile of SLTs across the region is presented. Results indicated that the workforce of SLTs comprised a mix of local and international SLTs, with university-level education. Local SLTs were educated both within and outside of Africa, with more recent graduates trained in Africa. These data reflected the local emergence of speech and language therapy training in SSA.


Conclusion: This sample comprised a mix of African and international SLTs, with indications of growing localisation of the workforce. Workforce localisation offers potential advantages of linguistic diversity and stability. Challenges including workforce support and developing culturally and contextually relevant SLT practices are discussed.

Purpose:

The African Disability Scooter (ADS) was developed for lower limb amputees, to improve mobility and provide access to different terrains. The aim of this study was to test the efficiency of the ADS in Africa over different terrains.

 

Method: 

Eight subjects with a mean age of 12 years participated. Energy expenditure and speed were calculated over different terrains using the ADS, a prosthetic limb, and crutches. Repeated testing was completed on different days to assess learning effect. 

 

Results:

Speed was significantly faster with the ADS on a level surface compared to crutch walking. This difference was maintained when using the scooter on rough terrain. Oxygen cost was halved with the scooter on level ground compared to crutch walking. There were no significant differences in oxygen consumption or heart rate. There were significant differences in oxygen cost and speed between days using the scooter over level ground, suggesting the presence of a learning effect. 

 

Conclusions:

This study demonstrates that the ADS is faster and more energy efficient than crutch walking in young individuals with amputations, and should be considered as an alternative to a prosthesis where this is not available. The presence of a learning effect suggests supervision and training is required when the scooter is first issued.
