Assessing the outcome of mobility assistive technology (OMAT) in daily living: results in an Italian sample

BACKGROUND

Despite the widely recognised benefits of assistive technology (AT) in everyday life, AT abandonment rate due to unmet user needs or expectations is high. World Health Organisation emphasised the importance of evaluating AT outcomes as a top research priority, but comprehensive approaches to assess users' needs and AT impact are still limited.

AIM

The research study OMAT (outcomes of mobility assistive technology in rehabilitation pathways) aimed to evaluate the feasibility of a new AT assessment protocol for mobility AT, spanning from an initial evaluation of users' and relatives' needs to a follow-up after real-world use of assistive products (APs).

MATERIAL AND METHODS

An observational single-arm study involving 95 AT users was conducted at Fondazione Don Gnocchi (Milan, Italy). The OMAT protocol encompassed baseline assessment, user training, prescription, authorisation, delivery and follow-up. The evaluations blend standard clinical evaluations with validated AT outcome measures for perceived effectiveness of AT, user satisfaction and changes in quality of life.

RESULTS

The feasibility of OMAT in clinical settings was established, with 67 user participants completing the protocol. Data showed positive impacts on user satisfaction and perceived AT effectiveness by all participants (users and relatives), with an improvement in the perceived degree of severity in problems. Quality of life outcomes, however, showed mixed results across various domains.

CONCLUSION

OMAT is a feasible protocol for assessing mobility APs in clinical settings, underscoring the importance of involving users in the prescription process and the need for comprehensive AT monitoring mechanisms. This approach could enhance AT service delivery, exceeding the current standards of the Italian-National-Health-Service.Implication for rehabilitationPersonalise assistive technology (AT) based on user needs for higher effectiveness.Include structured follow-up in rehabilitation for better AT outcomes.Enhance patient involvement in AT selection to improve use.Focus on AT's role in enhancing overall quality of life.Use validated tools for AT impact assessment and monitoring.

A systematic review of the psychometric properties of Quebec user evaluation of satisfaction with assistive technology (QUEST)

PURPOSE

The aim of this systematic review was to evaluate the psychometric properties of the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST).

MATERIALS AND METHODS

Searches were conducted in August 2021 on four electronic databases: MEDLINE, CINAHL, Scopus, and Web of Science. Eligible papers included cross-sectional validation studies evaluating the psychometric properties of all QUEST versions. Cronbach's alpha, intraclass correlation coefficient, and comparison tools were reported. Study quality and risk of bias were assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist.

RESULTS

Nineteen studies were included in this systematic review. Results showed that the QUEST and QUEST 2.0 were available in 10 languages, and most validation studies analysed this tool in patients using mobility devices in various clinical conditions. One article analysed the child version (QUEST 2.1) in English. The most analysed psychometric property was Cronbach's alpha for internal consistency in 14 out of 19 studies, with values ranging between 0.74 and 0.79. Overall, 17 out of 19 studies were of adequate quality, though responsiveness was never studied.

CONCLUSION

Our systematic review showed that the QUEST and its subsequent versions are reliable and valid measurement instruments to evaluate satisfaction in patients with different disabilities using various assistive technologies. This study provides useful information on the instrument's psychometric properties in different populations and cultures.

Iranian translation and psychometric of the Quebec user evaluation of satisfaction with Assistive technology (QUEST2.0) on wheelchair users

PURPOSE

QUEST2.0 is a practical tool specifically applied to assessing the satisfaction for awide array of assistive technology in a standard manner. Therefore, this study set to translate and evaluate the validity and reliability of the Iranian version of the QUEST2.0in Persian-speaking users of manual and electronic wheelchairs in Iran.

METHODS

The present study recruited 130 users of manual and electric wheelchairs. Psychometric properties, including; content validity and construct validity and internal consistency and test-retest reliability, were testified.

RESULTS

The content validity index of the questionnaire was 92%. The internal consistency was determined to be 0.89,0.88 and 0.74, respectively, for the whole questionnaire and dimensions of the device, and services. The test-retest reliability was 0.85, 0.80, and 0.94, respectively, for the whole questionnaire and dimensions of the device and services. Factor analysis confirmed the two-factor structure of the questionnaire. In the two-factor model, 57.75% of the total variance was explained by these two factors, of which 45.8% pertained to the first factor (device) and 11.95% to the second factor (service).

CONCLUSIONS

The results showed that QUEST2.0 had both valid and reliable for measuring satisfaction with assistive technology among wheelchair users. The assessment will also help facilitate the quality improvement processes in using assistive technology devices.

Patient Satisfaction with Occupational Therapy Services for Wheeled Mobility and Seating Devices

Satisfaction of 81 patients was evaluated before and after receiving occupational therapy services. There was a statistically significant difference between patients' scores before and after receiving occupational therapy services (p < .05). Over 85% indicated a high satisfaction in relation to quality and health outcomes attributed to occupational therapy services, 44% reported barriers related to limited availability, accessibility, and knowledge of occupational therapy services, and 35% made suggestions for improvements. Patient-therapist communication and easy access to occupational therapy services can enhance occupational therapy knowledge, lead to positive patient experience and quality health outcomes, and higher patient satisfaction.

Cross-Cultural Validation of Quebec User Satisfaction with Assistive Technology 2.0 for Spanish Population (QUEST-2.0 ES)

Background: Assistive technologies (ATs) are resources to promote the independence and participation of people with a disability. The use of standardized tools, based on outcome measures, is essential for guaranteeing high-quality rates. The Quebec User Evaluation of Satisfaction with AT–2.0 (QUEST) is a scale to assess the satisfaction of people using any AT. Objectives: To translate and culturally validate the QUEST–2.0 for the Spanish population (QUEST 2.0-ES). Methods: A validation cross-design and descriptive study. The test–retest reliability, validity, and internal consistency of QUEST 2.0-ES were studied. It was divided into two phases: Sample 1 was formed by 26 persons; in sample 2, 30 persons participated. The conditions included neurological conditions, amputations, rare diseases, and deafness. Results: Thirty-five men and 21 women participated in total. The majority of AT used were those for mobility. QUEST 2.0-ES analysis showed internal consistency values between the test (α = 0.87) and retest versions (α = 0.89). The internal consistency was high for AT (test, α = 0.83; retest, α = 0.87) and Service (test, α = 0.80; retest, α = 0.80). The temporal reliability (1–2 weeks) for test–retest was 0.88. Conclusion: QUEST 2.0-ES showed good psychometric properties in terms of validity and test–retest reliability, and it is a good tool to assess the user’s satisfaction with ATs and services.

Sports Injuries Among Players of the Polish National Team in Amputee Football in the Annual Training Cycle

The aim of the study was to determine the frequency, type and origin of the occurrence of injuries in amputee football. The studied group comprised all members of the Polish national amputee football team (n = 25). During the 9-month observation period, 13 players incurred 22 injuries. The incidence proportion was 48.0 per 100 athletes (95% Cl, 28.4-67.6) and the incidence rate was 5.73 per 1000 athlete-days (95% Cl, 3.33-8.12). The study showed that 32.8% of the injuries were to the thigh, 13.6% to the ankle, and 9.1% to the knee. The obtained results indicate that amputee football players rather frequently incur play-related injuries, but a single athlete incurs relatively few of them, with the lower limb being most commonly injured.

Mobility devices for children with physical disabilities: use, satisfaction and impact on participation

INTRODUCTION

Children with physical disabilities commonly use mobility devices. There is a lack of studies on the use and impact of mobility devices on activities and participation. Research is needed on satisfaction with the service delivery process of mobility devices.

PURPOSE

To examine the use and impact of mobility devices among children with physical disabilities and the satisfaction with the properties of their mobility devices and related services.

MATERIALS AND METHODS

A web-based survey was sent to parents of 6 - 18 years old children with physical disabilities who used mobility devices in Iceland. The use and effectiveness of mobility devices were assessed with a questionnaire designed for this study. The satisfaction was measured with Quebec user evaluation of satisfaction with assistive technology (QUEST) 2.0.

RESULTS

The survey was sent to 55 families and 36 replied. Most of the children used mobility devices in social activities. The number of participants who reported positive effects of devices on activities and participation, depended on environmental settings. There was no significant difference in participants' satisfaction between types of mobility devices. Also, there was no significant difference in participants' satisfaction with the properties of the device and the related service (for wheeled walkers p = 0.47, manual wheelchairs p = 0.08, powered wheelchairs p = 1.00).

CONCLUSIONS

The results indicate the importance of mobility devices for activities and participation and can guide healthcare workers when providing mobility devices where environmental factors across settings must be kept in mind. Stakeholders should be aware of the value of satisfaction with the devices and related services.Implications for Rehabilitation:Children with physical disabilities use mobility devices across different environmental settings and need to have more than one type of equipment.This study confirms results from earlier research that mobility devices are important for the activities and participation of children with disabilities.It is important to understand how the delivery process of devices is perceived by those who receive them. High satisfaction is an indicator of high quality of service.Environmental factors across settings must be kept in mind in the delivery process of assistive devices.

Evaluation of satisfaction with geospatial assistive technology (ESGAT): a methodological and usability study

Purpose: Manual wheelchair users are more vulnerable, in situations such as road crossings, hazardous sidewalks or curbs and crossing of buildings and facilities threshold. Geospatial assistive technology (GAT) can help with route planning. However, it is important to ensure the usability of such products, as well as the satisfaction of persons with reduced mobility. The study's aim was (1) to develop and validate a questionnaire on the satisfaction of GAT, in English and French, and to (2) assess satisfaction, efficacy and efficiency of a GAT with manual wheelchair users following a filmed trial in a dense urban area.Method: A methodological study was conducted (development of the questionnaire, assessment of its content validity, feasibility and practicability) followed by a trial and post-observations with the videos. Two questionnaires (English, French) were concurrently validated by two groups of experts (n = 8), and then field-tested by wheelchair users (n = 8), using Google Maps Pedestrian routeing tool.Results: The Evaluation of satisfaction with geospatial assistive technology (ESGAT) consists in a user profile and their experience with the technology, followed by 12 satisfaction criteria rated from 1-not satisfied to 5-very satisfied. Both questionnaires were rated as feasible and practicable to complete. The usability of Google Maps Pedestrian routeing tool was measured as "moderate" by manual wheelchairs since the total satisfaction score at the ESGAT was 3.9/5 (quite satisfied). The items with the lowest score were navigation assistance, hands-free function and security. The GAT was effective (87.5% have completed their destination) but not efficient (37.5% needed help).IMPLICATIONS FOR REHABILITATIONFor manual wheelchair users paired with geospatial assistive technology:• A 10 minutes questionnaire was developed and validated to assess their satisfaction after testing aid in an urban area.• Satisfaction criteria to address are ease of access (service), learnability, hands-free function, ease of use for planning as well for navigating, transportability/ appearance, content, geographic information, effectiveness, efficiency, navigation assistance and security• A field test is necessary to ensure the effectiveness of the technology in avoiding or announcing potential obstacles such as sidewalk crossing ramp, damaged and congested sidewalk; sidewalk tilt (side slopes); thresholds at destination; verbal indication too soon or too late; incorrect indication; the arrow does not indicate the right direction; readjustment of the route needed; a lack of indication; and human intervention needed.

Psychosocial Impact of Powered Wheelchair, Users’ Satisfaction and Their Relation to Social Participation

Several studies showed positive effects of assistive technologies on psychosocial impact and participation of adults with mobility impairments. The purpose of this study was to assess the psychosocial and participation impact of powered wheelchairs. Participants were thirty persons with disabilities who use powered wheelchairs with diverse medical conditions. The Quebec User Evaluation of Satisfaction with Assistive Technology, the Psychosocial Impact of Assistive Devices Scale and the Activities and Participation Profile Related to Mobility were used, in addition to demographic, clinical and wheelchair related questions. The participants were satisfied with both the assistive technology and related services, with the lowest satisfaction scores belonging to those who had been using their wheelchairs for a longer period of time. We noticed significant restrictions in participation mostly among persons with longer wheelchair utilization. The most satisfied were the ones with better performance in terms of social participation. Psychosocial scores showed a positive impact with higher adaptability among persons who transitioned from a manual compared to those who already had a powered wheelchair. There was a positive psychosocial impact and therefore an increase in quality of life of its users.

Orthosis Comfort Score: Establishing initial evidence of reliability and validity in ankle foot orthosis users

BACKGROUND

Comfort of an orthosis is an important characteristic that is likely to dictate use of and satisfaction with a device. However, instruments to assess only orthosis user comfort do not exist. The Prosthetic Socket Fit Comfort Score, developed previously for prosthesis users, may be adapted to serve this purpose.

OBJECTIVES

This study's purpose was to assess the validity and reliability of the Orthosis Comfort Score, a self-report instrument adapted from the Prosthetic Socket Fit Comfort Score.

STUDY DESIGN

This is a prospective, observational study designed to establish initial evidence of validity and reliability for an outcome measure that assesses comfort.

METHODS

Ankle foot orthosis users completed the Orthosis Comfort Score and two validated patient satisfaction questionnaires. An orthotist documented an assessment of fit. Post-visit Orthosis Comfort Scores were documented after the appointment and 2-4 weeks later. Orthosis Comfort Scores were compared to the patient satisfaction questionnaires, assessment of fit and orthosis use (hours per week).

RESULTS

There were 46 study participants. Orthosis Comfort Scores had a moderate positive correlation with their orthotist's assessment of fit, very strong positive correlations with patient satisfaction questionnaires and fair positive correlation with orthosis use (all correlations p < 0.05).

CONCLUSION

This study demonstrates initial evidence for the validity and reliability of the Orthosis Comfort Score in ankle foot orthosis users.

CLINICAL RELEVANCE

The Orthosis Comfort Score is a simple patient-reported outcome measure that can be readily incorporated into clinical practice or research study to obtain a rapid assessment of comfort. It can be used to facilitate communication about device fit, evaluate comfort over time and/or assess changes in comfort with a new device.

Exploring Validity, Reliability, and Factor Analysis of the Quebec User Evaluation of Satisfaction with Assistive Technology in an Italian Population: A Cross-Sectional Study

This study explores validity, reliability, and factor analysis of the Quebec User Evaluation of Satisfaction with Assistive Technology (IT-QUEST) for users of assistive technology devices in an Italian population. It was administered to 75 people to determine which of the 24 original items were relevant to the Italian context using exploratory and confirmatory factor analyses (EFAs and CFAs) were conducted with internal consistency and test-retest reproducibility also evaluated. The EFA and CFA showed that the 24-item survey may have limited relevance to the Italian context. We individuated 12 significative items, divided into two subscales, as well as the original validation. The test-retest showed high values of the Intraclass Correlation Coefficient (ICC) (0.7-0.9), with a 0.812 ICC for the total scale providing support and evidence for Italian professionals to evaluate user satisfaction with assistive technology devices. This research also lays the foundation for developing a validation study of the IT-QUEST 2.0 that is relevant to the Italian culture. Further research may investigate psychometric properties involving more participants and different users of assistive technology devices.

Pain, fatigue, function and participation among long-term manual wheelchair users partnered with a mobility service dog

PURPOSE

To assess the effects of a mobility service dog (MSD) on pain, fatigue, wheelchair-related functional tasks, participation and satisfaction among manual wheelchair users over a nine-month period.

METHOD

A longitudinal study with repeated assessment times before and three, six and nine months after intervention was achieved. Intervention consisted in partnering each participant with a MSD. The setting is a well-established provincial service dog training school and participants homes. A convenience sample of 24 long-term manual wheelchair users with a spinal cord injury was involved. Outcome measures were: Wheelchair User's Shoulder Pain Index (WUSPI), Rate of Perceived Exertion (RPE), vitality scale from the SF-36, grip strength, Wheelchair Skills Test (WST), Canadian Occupational Performance Measure (COPM), Reintegration to Normal Living Index (RNLI), Life Space Assessment, Psychosocial Impact of Assistive Devices Scale (PIADS) and Quebec User Evaluation of Satisfaction with assistive Technology (QUEST 2.0).

RESULTS

Shoulder and wrist pain as well as fatigue decreased significantly over time with the use of a MSD as evidenced by scores from WUSPI, RPE and SF-36 (feeling less worn out). Manual wheelchair propulsion skills (steep slopes, soft surfaces and thresholds) improved significantly over time as confirmed by the WST. Participation increased significantly over time as revealed by the COPM (for five occupations) and the RNLI (for five items). Satisfaction with the MSD was high over time (QUEST: nine items) and with a high positive psychosocial impact (PIADS: 10 items).

CONCLUSION

MSD represents a valuable mobility assistive technology option for manual wheelchair users. IMPLICATIONS FOR REHABILITATION   For manual wheelchair users partenered with mobility service dog  • Shoulder pain and fatigue significantly decreased and continued to decrease between the third and sixth month and the ninth month.   • Performance with propelling the wheelchair up steep slopes increased from 41 to 88% and on soft surfaces increased from 53 to 100% after 3 months, respectively.   • Occupational performance satisfaction was significantly increased for mobility in relation with the transfers, navigating in a natural environment and picking up objects.   • High satisfaction towards psychosocial competency, psychosocial adequacy and self-esteem were reported at months three, six and nine.

Assessing the Outcomes of Equipment and Adaptations: Issues and Approaches

Current government policy emphasises professional accountability, Best Value, evidence-based practice and outcomes for users and carers. In this context, being able to demonstrate the effectiveness of routine practice is increasingly important.

This article considers the key issues in collecting information about the outcomes of equipment and adaptations. These include: the assessment of the full range of outcomes; the timing of data collection; the use of standardised and individualised measures; and linking outcomes to interventions. Three approaches to evaluating the outcomes of equipment and adaptations are distinguished: functional status measures; health status or quality of life measures; and indirect approaches. Examples of each approach are provided and their strengths and limitations discussed.

Previous work on the outcomes of equipment and adaptations has neglected the perspectives of carers and the impact of service delivery (service process outcomes); further work on these areas is needed to ensure that all the outcomes of equipment and adaptations are fully evaluated.

An Investigation of the Effectiveness of the Quebec User Evaluation of Satisfaction with Assistive Technology via a Postal Survey

The need to involve users of assistive technologies in the evaluation of equipment has been stressed consistently and linked directly with equipment use. However, in clinical practice obtaining feedback that is informed by prolonged use within the home can be difficult to achieve owing to current working practices. This paper describes the experience of using the Quebec User Evaluation of Satisfaction with Assistive Technology in a postal survey and discusses the potential application of this method of administration in routine practice to obtain user evaluation.

Use of a Modified Canadian Occupational Performance Measure for Assistive Technology Outcomes in Postsecondary Education

The Canadian Occupational Performance Measure (COPM) has been used to assess the effectiveness of assistive technology (AT). We explored whether a modified COPM was sensitive to change in perceived performance and satisfaction, and whether frequency of AT use resulted in greater change in the domains measured (reading, writing, note-taking, test-taking, and study skills). Significant interactions were found between time and use frequency with greater change in perceived performance in the daily-use group in several domains. In addition, the intra-class correlation showed moderate to strong equivalent forms reliability between two assessment formats. Based on these preliminary results, the ATRC-mCOPM was found to be a sensitive measure of perceived performance and satisfaction utilizing AT services in a postsecondary education setting.

The Effect of Training Older Adults with Stroke to Use Home-Based Assistive Devices

This study evaluated whether an additional home training program on bathing devices would improve the rate of use, personal independence, and service satisfaction of older adults who had experienced strokes. A prospective pretest and posttest randomized control trial design was adopted. Fifty-three older adults who had experienced strokes were randomly assigned to either the intervention group or the control group. The prescription of and training in the use of devices was conducted with both groups while they were in the hospital. The intervention group received additional home-based intervention in the use of devices immediately after discharge, but the control group did not. All of the subjects were assessed before discharge and 3 months after discharge using the Functional Independence Measure and the Quebec User Evaluation of Satisfaction with Assistive Technology. The results showed that the intervention group improved significantly in functioning ( t = 3.89; df = 51; P = .01) and satisfaction ( t = 69.8; df = 29; P = .01) after intervention. The rate of use of bathing devices was relatively higher in the intervention group (96.7%) than in the control group (56.5%). Further studies with extended follow-up services are needed to evaluate the long-term effects of training in the use of assistive devices.

Enhancing the Communication of Suddenly Speechless Critical Care Patients

BACKGROUND

Sudden speechlessness is common in critically ill patients who are intubated or have had surgery for head and neck cancer. Sudden inability to speak poses challenges for hospitalized patients because strategies to facilitate communication are often limited and unreliable.

OBJECTIVE

To determine the impact of a technology-based communication intervention on patients' perception of communication difficulty, satisfaction with communication methods, and frustration with communication.

METHODS

A quasi-experimental, 4-cohort (control and intervention) repeated-measures design was used. Data were collected daily for up to 10 days. Patients in adult critical care units were followed up as they were transferred to other units within the institutions selected for the study. The impact of a technology-based communication system (intervention) was compared with usual care (control). Patients' communication outcomes pertinent to communication with nursing staff that were evaluated included perception of communication ease, satisfaction with methods used for communication, and frustration with communication.

RESULTS

Compared with participants in the control group, participants in the intervention group reported lower mean frustration levels (-2.68; SE, 0.17; 95% CI, -3.02 to -2.34; P < .001) and higher mean satisfaction levels (0.59; SE, 0.16; 95% CI, 0.27 to 0.91; P < .001) with use of the communication intervention. Participants in the intervention group reported a consistent increase in perception of communication ease during the hospital stay.

CONCLUSIONS

The results facilitated evaluation of a bedside technology-based communication intervention tailored to the needs of suddenly speechless critically ill patients.

Actual use of and satisfaction associated with rollators and "shopping carts" among frail elderly Japanese people using day-service facilities

Purpose This study aimed at clarifying the actual use of and satisfaction with rollators and "shopping carts" (wheeled walkers with storage) among frail elderly people, who were certified by a long-term care insurance system as users of facilities that provide day-service nursing care and rehabilitation. Methods We identified 1247 frail elderly people who used day-service facilities, and evaluated their actual use of, and satisfaction with, rollators and shopping carts. Results Forty-four (3.5%) individuals used rollators, and 53 (4.3%) used shopping carts. The shopping cart group contained more individuals who were certified as care level 1 (26.4%), than the rollator group (20.5%), and 52.8% of the shopping cart group was certified as care levels 1-3. The scores for "repairs and services" and "follow-up" from the Quebec User Evaluation of Satisfaction with assistive Technology second version (QUEST 2.0) survey were significantly higher in the rollator group than in the shopping cart group. Conclusions The QUEST 2.0 scores revealed that shopping cart users exhibit insufficient "repairs and services" and "follow-up" scores. As frail elderly people with poor care status accounted for >50% of the shopping cart group, these individuals urgently need walking aids that are tailored to their care status. Implications for Rehabilitation We conclude that walking aid fitting must be tailored to each persons care status, and suggest that a system should be established to allow occupational or physical therapists to provide this fitting Moreover, our analysis of the QUEST2.0 service scores revealed that repairs, services, and follow-up are insufficient to meet the needs of shopping cart users.

Outcome Measures for Wheelchair and Seating Provision: A Critical Appraisal

Introduction:

Every aspect of the wheelchair and seating provision process has an impact on overall outcomes for service users. This critical appraisal sought to identify outcome measures suitable for evaluation of wheelchair and seating provision, considering activity, participation, and impact of the service delivery on quality of life.

Method:

Outcome measures were identified using databases: Medline, CINHAL, PsychInfo, and Google Scholar. An evaluation was conducted to establish those that were particularly useful and a critical appraisal was completed.

Findings:

Five outcome measures identified as relevant for critical appraisal included: Wheelchair Outcome Measure; Functioning Every day in a Wheelchair; Goal Attainment Scale; Psychosocial Impact of Assistive Devices Scales; and the Quebec User Evaluation of Satisfaction with Assistive Technology. The strengths and limitations of each were identified.

Conclusion:

No single outcome measure captures all necessary information; trade-offs are inevitable. When choosing an outcome measure, the specific goals of the service evaluation and the resources available need to be considered within context. Critical appraisal of five outcome measures deemed appropriate for the evaluation highlighted some areas for consideration to inform decision making. A move towards sustainability indicators is suggested to monitor, measure, and respond to the provision processes and outcomes required to meet this primary need.

Use of an innovative model to evaluate mobility in seniors with lower-limb amputations of vascular origin: a pilot study

BACKGROUND

The mobility of older individuals has often been only partially assessed, without considering all important aspects such as potential (available) versus effective (used) mobilities and the physical and psychosocial factors that modulate them. This study proposes a new model for evaluating mobility that considers all important aspects, applied here to lower-limb amputees with vascular origin. This model integrates the concepts of potential mobility (e.g. balance, speed of movement), effective mobility (e.g. life habits, movements in living areas) and factors that modulate these two types of mobility (e.g. strength, sensitivity, social support, depression). The main objective was to characterize potential and effective mobility as well as mobility modulators in a small sample of people with lower-limb amputations of vascular origin with different characteristics. The second objective of this pilot study was to assess the feasibility of measuring all variables in the model in a residential context.

METHODS

An observational and transversal design was used with a heterogeneous sample of 10 participants with a lower-limb amputation of vascular origin, aged 51 to 83, assessed between eight and 18 months after discharge from an acute care hospital. A questionnaire of participant characteristics and 16 reliable and valid measurements were used.

RESULTS

The results show that the potential mobility indicators do not accurately predict effective mobility, i.e., participants who perform well on traditional measures done in the laboratory or clinic are not always those who perform well in the real world. The model generated 4 different profiles (categories) of participants ranging from reduced to excellent potential mobility and low to excellent effective mobility, and characterized the modulating factors. The evaluations were acceptable in terms of the time taken (three hours) and the overall measurements, with a few exceptions, which were modified to optimize the data collected and the classification of the participants. For the population assessed, the results showed that some of the negative modulators (particularly living alone, no rehabilitation, pain, limited social support, poor muscle strength) played an important role in reducing effective mobility.

CONCLUSION

The first use of the model revealed interesting data that add to our understanding of important aspects linked to potential and effective mobility as well as modulators. The feasibility of measuring all variables in the model in a residential context was demonstrated. A study with a large number of participants is now warranted to rigorously characterize mobility levels of lower-limb amputees with vascular origin.

Cross-cultural adaptation and validation of the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0): the development of the Taiwanese version

Objective: To develop and validate a cross-cultural version of the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) for users of assistive technology devices in Taiwan.

Design: A cross-sectional survey.

Procedures: The standard cultural adaptation procedure was used for questionnaire translation and cultural item design. A field test was then conducted for item selection and psychometric properties testing.

Subjects: One hundred and five volunteer assistive device users in community.

Main outcome measures: A questionnaire comprising 12 items of the QUEST 2.0 and 16 culture-specific items.

Results: One culture-specific item, ‘Cost’, was selected based on eight criteria and added to the QUEST 2.0 (12 items) to formulate the Taiwanese version of QUEST 2.0 (T-QUEST). The T-QUEST consisted of 13 items which were classified into two domains: device (8 items) and service (5 items). The internal consistencies of the device, service and total T-QUEST scores were 0.87, 0.84 and 0.90, respectively. The device, services and total T-QUEST scores achieved good test-retest stability (intraclass correlation coefficient (ICC) 0.90, 0.97, 0.95). Exploratory factor analysis revealed that T-QUEST had a two-factor structure for device and service in the construct of user satisfaction (53.42% of the variance explained).

Conclusions: Users of assistive device in different culture may have different concerns regarding satisfaction. T-QUEST is the first published version of QUEST with culture-specific items added to the original translated items of QUEST 2.0. T-QUEST was a valid and reliable tool for measuring user satisfaction among Mandarin-speaking individuals using various kinds of assistive devices.

Participation in community-based activities of daily living: comparison of a pushrim-activated, power-assisted wheelchair and a power wheelchair

PURPOSE

The purpose of this study was to evaluate pushrim-activated, power-assisted wheelchair (PPW) performance among dual-users in their natural environment to determine whether the PPW would serve as a satisfactory alternative to a power wheelchair for community-based activities.

METHODS

A concurrent mixed methods research design using a cross-over trial was used. The outcome measures used were number of hours reported using the different wheelchairs, Quebec User Evaluation of Satisfaction with assistive Technology (QUEST), Functioning Everyday with a Wheelchair (FEW), Psychosocial Impact of Assistive Devices Scale (PIADS) and Canadian Occupational Performance Measure (COPM).

RESULTS

The number of hours spent participating in self-identified activities was not significantly different. Only the Self-Esteem subscale of the PIADS identified a statistically significant difference between the PPW and power wheelchair conditions (p = 0.016). A clinically important difference for Performance and Satisfaction was suggested by the COPM, in favour of the power wheelchair.

CONCLUSIONS

Additional knowledge was gained about the benefits of PPW technology. Participants were able to continue participating independently in their self-identified community activities using the PPW, and identified comparable ratings of satisfaction and performance with the PPW and the power wheelchair. For some individuals requiring power mobility, the PPW may provide an alternative to the power wheelchair.

User satisfaction with mobility assistive devices: An important element in the rehabilitation process

BACKGROUND

An assistive device often means an evident change in a person's ability, more easy to notice than the effects of most of other types of physiotherapy or occupational therapy intervention. In spite of this, there is very little evidence in this area.

PURPOSE

The objective was to follow-up user satisfaction with and the use and usefulness of rollators and manual wheelchairs. The objective was also to determine any difference in satisfaction between users of the two different types of mobility assistive products.

METHODS

A random sample of 262 users participated in the study, 175 rollator users and 87 wheelchair users. The Quebec User Evaluation of Satisfaction with Assistive Technology-QUEST 2.0 and an additional questionnaire were used for data collection.

RESULTS

Overall satisfaction with both types of device was high and most clients reported use of their device on a daily basis. There was a difference in how the users estimated the usefulness and other characteristics as well as some service aspects related to prescription and use of the two types of device. Most users reported not having had any follow-up; however, most users had not experienced any need for one.

CONCLUSIONS

A standardized follow-up will give rehabilitation professionals continuous and valuable information about the effect of and satisfaction with assistive devices.

The Validity and Applicability of the Chinese Version of the Quebec User Evaluation of Satisfaction With Assistive Technology for People With Spinal Cord Injury

The Quebec User Evaluation With Assistive Technology (Version 2.0; QUEST 2.0) has become an important outcome assessment to capture user satisfaction in the field of assistive technology. The purpose of this study is to investigate the psychometric properties of the Chinese version of the QUEST 2.0 (C-QUEST) in terms of content and substantive and factor validity and to explore its applicability on user satisfaction on mobility and equipment among Chinese people with spinal cord injury. A group of six expert members were invited to evaluate the content validity and translation quality of the 12-item C-QUEST. The revised version, along with the brief version of the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF [HK]), was administered on user satisfaction of people with spinal cord injury in the community. The content validity and item performance were evaluated to be satisfactory. Exploratory factor analysis with varimax rotation agreed with the bidimensional structure of Device and Services in the construct of user satisfaction (61.06% variance explained). Items in WHOQOL-BREF (HK) were shown to have positive and moderate correlations with C-QUEST Device items (r = .412-.567, p < .05) but no significant associations with the Services items (p > .05). The 12-item C-QUEST was shown to be a valid and relevant instrument to capture the user satisfaction among Chinese people with spinal cord injury in the context of mobility and seating equipment.

Outcomes of wheelchair systems intervention with residents of long-term care facilities

This pilot study was designed to measure the effects of individually prescribed wheelchair systems on posture and reach, mobility, quality of life, and satisfaction with technology for residents of long-term care facilities. Thirty persons 60 years of age or older who resided permanently in a long-term care facility and who used seating and mobility systems for 6 hours or more each day were recruited for this project. Outcomes included timed independent mobility, forward and lateral reach, quality of life, and satisfaction with assistive technology. The study used semicrossover design with participants measured three times. Measurements were first made in the existing seating and mobility system and a second time immediately after participants were provided with individually prescribed seating and mobility systems. The final measurement was 3 months after the delivery of the individually prescribed system. Results indicated that individually fitted wheelchair systems for elderly residents of long-term care facilities are beneficial. Participants had less difficulty independently propelling their systems and increased forward reach, quality of life for social function and physical role, and satisfaction with the new wheelchair technology. Persons residing in extended care facilities benefit from receiving individually prescribed wheelchair systems. The individual systems enhance elderly persons' independent mobility, functional reach, feeling of well-being, and satisfaction with their assistive technology.

Item analysis of the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST)

The Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST) is an outcomes assessment tool designed to measure satisfaction with assistive technology in a structured and standardized way. The purpose of this article is to present the results of an analysis of the 24 items comprising QUEST and to explain how a subset of items demonstrating optimal measurement performance was selected. The criteria against which the items were measured were general acceptability, content validity, contribution to internal consistency, test-retest stability, and sensitivity. The items that ranked best in terms of these measurement properties were submitted to factorial analysis in order to complete the item selection. The first series of analyses reduced the item pool approximately by half, and the second series of analyses led to the final selection of 12 items. Factor analysis results suggested a bidimensional structure of satisfaction with assistive technology related to the assistive technology device (eight items) and services (four items). The 12-item revised version that will result from this study should prove to be a reliable and valid instrument for measuring outcomes in the field of assistive technology.
