Purpose: This research paper examines how contouring of a wheelchair seating base can help prevent pressure sores by distributing pressure over the buttocks. Contouring wheelchair cushioning is already done to some extent and has proved to be beneficial for pressure distribution. We researched the effect of contouring the seating base, and whether contouring the seating base affects effectiveness in pressure distribution and perceived discomfort.

Materials & methods: 13 healthy participants performed a within-subject experiment with three differ- ently contoured seating bases. Perceived comfort and seating pressure were measured for each condition.
Results: Results indicate that a more contoured base is positive for both comfort and increased pressure distribution.

Conclusions: Contoured seating bases can provide increased comfort and improved pressure distribution over flat seating bases. Future research should examine the effect of contouring on stability, as well as compare the effects of contoured seating bases and contoured cushions.

Purpose

Appropriate wheelchair provision is necessary for addressing participation barriers experienced by individuals with mobility impairments. Health care professionals involved in the wheelchair service provision process require a specific set of skills and knowledge to enable wheelchair use that meets individual posture, mobility and daily living requirements. However, inconsistencies exist in academic programmes globally about providing comprehensive education and training programmes. The planned scoping review aims to review and synthesize the global literature on wheelchair service provision education for healthcare professional students, healthcare personnel and educators offered by universities, organizations and industries.

Methods

This scoping review will be guided by the Joanna Briggs Institute (JBI) methodological framework. Comprehensive literature searches will be conducted on various global electronic databases on health to seek out how wheelchair service provision education is organized, integrated, implemented and evaluated. Two independent reviewers will perform eligibility decisions and key data extractions. Data from selected studies will be extracted and analysed using conventional content analysis. Information related to wheelchair service provision education including curriculum development, content, teaching methods, evaluation and models of integration will be synthesized.

Implications and dissemination

The planned scoping review will be the first to examine all aspects of wheelchair service provision education across professionals, settings and countries. We anticipate that results will inform the content of a Wheelchair Educators’ Package, and if appropriate, a follow-up systematic review. An article reporting the results of the scoping review will be submitted for publication to a scientific journal.

Purpose

Neuromuscular disorders are characterised by muscle weakness that limits upper extremity mobility, but can be alleviated with dynamic arm support devices. Current research highlights the importance and difficulties of evidence-based recommendations for device development. We aim to provide research recommendations primarily concerning upper extremity body functions, and secondarily activity and participation, environmental and personal factors.

Methods

Evidence was synthesised from literature, ongoing studies, and expert opinions and tabulated within a framework based on a combination of the International Classification of Functioning, Disability and Health (ICF) model and contextual constructs.

Results

Current literature mostly investigated the motor capacity of muscle function, joint mobility, and upper body functionality, and a few studies also addressed the impact on activity and participation. In addition, experts considered knowledge on device utilisation in the daily environment and characterising the beneficiaries better as important. Knowledge gaps showed that ICF model components and contextual constructs should be better integrated and more actively included in future research.

Conclusions

It is recommended to, first, integrate multiple ICF model components and contextual constructs within one study design. Second, include the influence of environmental and personal factors when developing and deploying a device. Third, include short-term and long-term measurements to monitor adaptations over time. Finally, include user satisfaction as guidance to evaluate the device effectiveness.

Purpose

To explore spouses’ experiences of the value of mobility scooters prescribed to their partner.

Material and Methods

A descriptive design with a qualitative approach was used. Thirteen spouses (11 females) aged 65–86 years participated. Semi-structured interviews were conducted when the spouse’s partner had had the mobility scooter for 4–6 months. The interviews were analysed using qualitative content analysis.

Results

The interviews showed primarily that the spouses experienced that their everyday lives and life situation had improved since their partner had received a mobility scooter. They reported that they could engage in activities of their own choice to a greater extent. The prescription of a mobility scooter to their partner had also yielded a sense of freedom related to shared activities. On the other hand, the spouses described some of the scooter’s limitations. Three categories emerged: a sense of freedom related to the spouse’s own activities, a sense of freedom related to shared activities and a somewhat restricted freedom.

Conclusion

Prescription of a powered mobility scooter was of value to the users’ spouses because it facilitated independent and shared activities and participation in the community. The value was mainly expressed as a sense of freedom when doing things on their own or together with their partner. Spouses are key persons in the rehabilitation of people with mobility restrictions. Their views on the assistive device may influence the rehabilitation process. Knowledge of spouses’ experiences is thus crucial, as this may influence the future rehabilitation outcome.

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.

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 examined speech and language pathologists’ (SLPs’) perceptions and practices of communication partner training with high-tech speech generating devices (SGDs).

Method: 

Fifteen SLPs were recruited throughout Sweden. The SLPs answered a study-specific questionnaire on communication partner training in relation to communication partners to children with severe cerebral palsy and intellectual disability. The results were analysed with descriptive statistics (closed-ended questions, responses on Likert scales) and content analysis (open-ended question) using ICF-CY.

Results:

Twelve SLPs completed the survey. Half had no or one training session with communication partners in the last year. One-third never used documents for goal-setting. Half seldom or never taught communication partner strategies. Three quarters only used verbal instructions. The main obstacles were environmental factors.

Conclusions: 

This study contributes valuable knowledge about high-tech SGD interventions targeting communication partners. The high-tech SGD intervention may benefit from goal-setting, extended number of training sessions and a range of instructional approaches.

Purpose:

Currently, there is no internationally accepted way to measure the competency of wheelchair service professionals. The International Society of Wheelchair Professionals aims to develop a Wheelchair Service Provision – Basic Test as a preliminary step towards establishing a certification process. 

Method:

A team of wheelchair service provision experts developed test questions and conducted alpha and beta testing in order to validate them. Low-performing test items were eliminated. A pilot test was then conducted, which focused on developing a pass score, determining language barriers and validating the test as a measure of competency. 

Results:

90 participants completed one of three versions of the Wheelchair Service Provision – Basic Test. A pass score of 70% was established and 135 questions were accepted for the final test. Analysis of variance indicated there was a difference in scores based on language (p = 0.001), but not based on experience level. This result motivated translation in to the United Nations’ official languages.

Conclusions:

The results indicate that the Wheelchair Service Provision – Basic Test is a valid method for measuring basic competency of wheelchair professionals. Additionally, researchers recommend a skills assessment to help to ensure only qualified wheelchair professionals receive the certificate.
