The QE Health Scale (QEHS): Assessment of the clinical reliability and validity of a spiritually based holistic health measure

Purpose.?To assess the clinical reliability and validity of a holistic health measure, the QE Health Scale (QEHS), for use with people with physical disabilities.

Method.?A test-retest design saw the QEHS administered and compared with established measures of health at admission and discharge from three-week inpatient rehabilitation programmes. Data was analysed by factor and correlation analysis. Clinician-reported credibility and usefulness of the theoretical basis of the QEHS, the QEHS itself, and Patient Profiles derived from the QEHS were also used to evaluate clinical validity.

Results.?The QEHS was judged to possess satisfactory reliability and validity.

Conclusion.?The QEHS is a clinically reliable, valid, credible and useful holistic health instrument to facilitate client-centred therapeutic interventions, inform decision-making and evaluate outcomes for people with physical disabilities.     

HIV/AIDS information and services: the situation experienced by adolescents with disabilities in Rwanda and Uganda

Purpose. The study had 2 aims: (1) To explore whether knowledge about HIV and AIDS was similar among adolescents with disabilities compared with their non-disabled peers; and (2) To determine factors which may increase vulnerability of disabled adolescents to HIV infection and/or inappropriate access to HIV related services.

Method. A qualitative study using focus group discussions and semi-structured interviews was conducted with purposefully selected participants in Rwanda and Uganda. The participants included disabled adolescents, non-disabled adolescents, parents, teachers, members of disabled people's organisations and representatives of HIV/AIDS organisations. Interviews explored issues of HIV/AIDS knowledge, access to HIV/AIDS services and perceptions of personal risk.

Results. Barriers preventing adequate access to information about HIV and AIDS experienced by adolescents with disabilities depended on the nature and severity of the impairment. For example, parents and health workers were unable to communicate with deaf adolescents using sign language, adolescents with physical impairments were often unable to access community meetings about HIV and print material was not adapted for those with visual impairments. Further, assumptions by health workers and community members that people with disabilities were not sexually active lead to the marginalisation of disabled people from HIV services. Adolescents with disability described low self esteem and issues of self efficacy affecting control of safer sexual relationships. A high level of targeted abuse, rape and exploitation was reported leading to vulnerability among this population.

Conclusion. The impact of the HIV epidemic among people with disabilities is a neglected area. This study supports the need to develop strategies in HIV prevention programmes that include people with disabilities.     

Leisure Time Physical Activity Instrument and Physical Activity at Home and Work Instrument. Development, face validity, construct validity and test-retest reliability for subjects with fibromyalgia

Purpose. A new instrument measuring leisure time physical activity (LTPAI) in populations predominately engaging in low intensity activities and a new instrument measuring the Physical Activity at Home and Work (PAHWI) were designed.

Methods. Patients with long-lasting pain and expert physiotherapists participated in the development of the two instruments. Test-retest reliability was evaluated for the LTPAI and the PAHWI. Construct validity was evaluated for the LTPAI by comparing it with an instrument measuring physical activities for older people, six-minute walk test and aerobic capacity.

Population. 37 women with FM, with the mean age of 46 years (SD 8.4) and mean symptom duration of 11 years (SD 5.9) were recruited to the study.

Results. The mean time that the study population spent in physical activities during leisure time was 5.2 hours (SD 4.0) a week. Satisfactory test-retest reliability was found for the total score of LTPAI (ICC 0.86, CI 0.79 - 0.93) and for the PAHWI (ICC 0.91, CI 0.82 - 9.96). A significant association between the LTPAI and the six-minute walk test (r_s 0.40, p = 0.02) and another physical activity instrument (r_s 0.39, p = 0.02) was found. As expected, LTPAI did not have any association with aerobic capacity.

Conclusions. Face validity of the instruments was ensured during the development process. Satisfactory test-retest reliability was found for the LTPAI and the PAHWI. Significant but low associations were found between the LTPAI and the six-minute walk test and an instrument designed for older people, respectively, while no association was found between the LTPAI and aerobic capacity.     

A participatory program evaluation of a systems change program to improve access to information technology by people with disabilities

Purpose. To pilot-test and evaluate an innovative program providing information technology (IT) access to people with disabilities transitioning out of nursing homes into the community using a participatory approach.

Methods. Pre- and post-training data was collected on the 61 program participants to reflect three broad areas related to the IT training experience: performance; self-efficacy; importance, satisfaction and control. Additionally, semi-structured interviews were conducted with seven participants and five members of the program staff to explore environmental barriers to IT access for this group and the efficacy of the program in addressing these barriers. Data analyses followed a mixed methods approach incorporating both qualitative and quantitative techniques.

Results. Participants showed substantive changes in different spheres of IT use after completion of training. Post-training changes were significant particularly in areas related to self-efficacy, importance and satisfaction pertaining to use of IT. Qualitative findings substantiated the quantitative results and also revealed the numerous barriers to IT access that persons with disabilities continue to face within their communities.

Conclusion. Results indicate the feasibility, effectiveness and value of IT access to people with disabilities particularly those transitioning from institutional life to community living. Further action research aimed at increasing IT access for this group within local communities and neighborhoods is needed to address this issue at a broader societal level.     

A pilot study of a web-based physical activity motivational program for adults with physical disabilities

Purpose. Develop, deliver, and assess the efficacy of a 4-week web-based leisure-time physical activity (LTPA) motivational program based on the Transtheoretical Model and tailored to inactive adults with physical disabilities.

Method. This was a pilot-based study incorporating a true experimental design with one treatment and one control group. The intervention program was delivered on the web and was based on the constructs of the Transtheoretical Model. From the 151 individuals who completed the LTPA standardized questionnaire at baseline, 75 people participated in the 1-month post-test assessment.

Results. The results of the analysis confirmed the pretest LTPA scores as the study covariate for the post-test assessment (F (1,72) = 16.06, p = 0.001, η² = 0.18). Based on the one-way ANCOVA, there were no statistically significant differences in LTPA scores between the treatment and control groups at post-test. However, the corresponding effect size and variance explained by the treatment approached a moderate level of significance (d = 0.34 and η² = 0.04).

Conclusions. Although conclusive statements about program effectiveness cannot be secured, several 'lessons learned' from this project may be 'key factors' for program improvement. Given the pilot nature of the study and the limited resources for program development and monitoring, continued examination of such motivational materials and delivery mechanisms for people with physical disabilities appear warranted.     

Use of health care among adults with chronic and complex physical disabilities of childhood

Purpose. The purpose of this study was to explore the patterns of health services utilization among adults with chronic and complex physical disabilities of childhood, specifically cerebral palsy, spina bifida, and acquired brain injuries.

Methods. A cohort of 345 young adults who had graduated from the Bloorview MacMillan Children's Centre was identified. Their health care records were extracted from Ontario Health Insurance Plan (OHIP) and Canadian Institute for Health Information (CIHI) databases, for a four-year period. These data were analysed to estimate the frequency of out-patient physician visits and admissions to hospital.

Results. The mean age of the sample was 21.9 years (range 19.0-26.9 years). The results show that 95% of the sample visited a physician at least once per year, and 24% had a primary care physician. On average, these adults visited physicians 11.5 times per year (approximately once per month) and were admitted to hospital once every 6.8 years.

Conclusions. These results suggest that adults with complex physical disabling conditions from childhood have ongoing health issues that require frequent service. Their admission rate is 9.0 times that of the general population, and few have a primary care physician. A new model of service may be necessary for this high-needs group.     

A systematic review of the Tardieu Scale for the measurement of spasticity

Background. The Tardieu Scale has been suggested a more appropriate clinical measure of spasticity than the Ashworth or modified Ashworth Scales. It appears to adhere more closely to Lance's definition of spasticity as it involves assessment of resistance to passive movement at both slow and fast speeds.

Objective. To review the available literature in which the Tardieu Scale has been used or discussed as a measure of spasticity, with a view to determining its validity and reliability.

Study design. A systematic review of all literature found related to the Tardieu Scale (keywords: Tardieu scale, spasticity) from Pubmed and Ovid databases, including medline, CINAHL, EMBASE, Journals at Ovid full text, EBM reviews and Cochrane database of systematic reviews. Hand searching was also used to track the source literature.

Conclusions. In theory, we can acknowledge that the Tardieu Scale does, in fact, adhere more closely to Lance's definition of spasticity. However, there is a dearth of literature investigating validity and reliability of the scale. Some studies have identified the Tardieu Scale to be more sensitive than other measures, to change following treatment with botulinum toxin. Further studies need to be undertaken to clarify the validity and reliability of the scale for a variety of muscle groups in adult neurological patients.     

The meaning of spirituality for individuals with disabilities

Purpose. To examine the experiences of people with disabilities regarding their spirituality and its meaning for them. This study asked: What are the differences in the meaning of spirituality in the lives of individuals with childhood onset disabilities when compared to those with adult onset disabilities?

Method. This qualitative study involved semi-structured individual interviews of 12 adults, six with childhood onset and six with adult onset disabilities. Member checking of both transcribed data and open coding was done to ensure trustworthiness. Data was analyzed using open, axial, and selective coding.

Results. Findings suggested that the two groups held different perceptions about the meaning of spirituality. For childhood onset participants, two categories of 'connecting and expressing for purpose and meaning in life', and 'disability as a vehicle to discover god's purpose' were generated. For adult onset participants, two categories of 'connecting and expressing through feelings and actions', and 'disability as a catalyst for spiritual awakening' were derived from the data.

Conclusions. Individuals with childhood and adult onset disabilities perceive and experience spirituality differently. Therefore, different approaches to using spirituality in practice need to be employed for the two groups. Suggestions are provided for incorporating spirituality into occupational therapy practice.     

Reliability and validity of The Awareness of Social Inference Test (TASIT): a clinical test of social perception

Purpose. The Awareness of Social Inference Test (TASIT) is an audiovisual tool designed for the clinical assessment of social perception with alternate forms for re-testing. Part 1 assesses emotion recognition, Parts 2 and 3 assess the ability to interpret conversational remarks meant literally (i.e., sincere remarks and lies) or non-literally (i.e., sarcasm) as well as the ability to make judgments about the thoughts, intentions and feelings of speakers. This paper aims to examine TASIT's reliability and validity.

Method. Some 32 adults with severe, chronic brain injuries were administered Form A twice, one week apart. 38 adults with brain injuries were readministered alternate forms over a period of 5 - 26 weeks. Construct validity was examined in subsets of a sample of 116 adults with brain injuries by relating TASIT performance to standard tests of neuropsychological function and specific social perception measures.

Results. Test-retest reliability ranged from 0.74 - 0.88. Alternate forms reliability ranged from 0.62 - 0.83. TASIT performance was associated with face perception, information processing speed and working memory. Socially relevant new learning and executive tasks were significantly associated with TASIT performance whereas non-social tasks showed little association. Social perception tasks such as Ekman photos and theory of mind stories were also associated.

Conclusions. TASIT has adequate psychometric properties as a clinical test of social perception. It is not overly prone to practice effects and is reliable for repeat administrations. Performance on TASIT is affected by information processing speed, working memory, new learning and executive functioning, but the uniquely social material that comprises the stimuli for TASIT will provide useful insights into the particular difficulties people with clinical conditions experience when interpreting complex social phenomena.     

What promotes physical activity after spinal cord injury? An interview study from a patient perspective

Purpose. Physical activity in people with traumatic spinal cord injury (SCI) is of importance not only for maintaining health but also for increasing the possibilities of living an independent life. Physical inactivity leads to poorer muscular and cardiovascular conditioning and sub-optimal levels of functioning. To help people with SCI to achieve optimum physical activity, it is important to understand what promotes the incorporation of regular physical activity into daily life. The aim of this study was thus to identify factors that may promote participation in physical activity among people with spinal cord injuries.

Method. Qualitative multiple case studies. Sixteen participants with SCI were interviewed.

Result. Four main themes of promoting factors could be identified. They were: using cognitive and behavioural strategies; finding supporting environmental solutions; exploring motivation post injury; and capturing new frames of reference.

Conclusion. By utilising the motivational power of role models, together with the other motivational factors identified in this study, such as identifying relevant individual motives post injury and capturing new frames of reference, the process towards physical active life may be facilitated.     

Investigation of health perspectives of those with physical disabilities: the role of spirituality as a determinant of health

Purpose: To identify key determinants of health and the process of health attainment for people with musculoskeletal disabilities.

Method: Focus groups of people with musculoskeletal disorders, including 30 members and their five trained facilitators, provided data. Discussed were 'What is health for you?' and 'What has helped, or would help you achieve this health?' Delphi-structured analysis identified health themes and a health process model was developed with the facilitators comprising the expert panel.

Results: Health was perceived as centred on relationships that required a spiritual awareness for a strong and resilient identity. The Self Attributes Model developed portrays the processes perceived to be required for health.

Conclusions: Although physical, social and psychological interventions are essential aspects of health intervention, by themselves they are not sufficient. Also required for health is a strong resilient self resulting from interaction and connection with other people and the natural world. Moreover, development of such an identity requires a spiritual world-view comprising an acknowledgement of the essence of self and focus upon the nature of the connection of this essence with all other aspects of life. Further research is required to advance understanding of the process by which this occurs for people with chronic disorders.     

The role of the spiritual dimension of the self as the prime determinant of health

Purpose. To present a clinical commentary on the relationship of spirituality to healthcare for those with chronic physical conditions.

Method. A spiritually based theory of self-identity was presented, based on selected literature to identify the process of health attainment for those with chronic conditions. The resultant Health Change Process Theory was then discussed in relation to relevant empirical research and the implications for rehabilitation practice were outlined.

Results. The development of a resilient, intrinsic, spiritually based concept of self was found to be pivotal to health outcomes in rehabilitation. This was then incorporated within a Health Change Process Theory to explain and predict the course followed by people with chronic disorders to achieve health.

Conclusion. The Health Change Process Theory provides an inclusive framework within which acute and chronic rehabilitation healthcare can be merged to maximise health outcomes. Nevertheless, a need remains to develop a quantitative measure of individual holistic health, based on this theory, to facilitate its use in rehabilitation practice. This paper forwards an explanation for the process that people experiencing chronic physical disabilities undergo as they achieve health. A concept of self that identifies the spiritual core as the component that determines the constancy and continuity of self as a whole which is necessary for health is presented as the basis of the rehabilitative health process.     

Adapting the Canadian Occupational Performance Measure for use in a paediatric clinical trial

Background. The Canadian Occupational Performance Measure (COPM) is a commonly used outcome measure in rehabilitation. In this study it was adapted for very young children by deleting paid/unpaid work and household management categories and having parents act as proxies to rate child performance and their own satisfaction.

Purpose. To assess the internal consistency reliability, content and construct validity, responsiveness, and impact of half scores (20 not 10-point scale) of the adapted COPM.

Method. Parent proxies of subjects aged 2 - 8 (mean 3.9) years with spastic hemiplegic cerebral palsy (n = 41) participating in a clinical trial. There was a total of 214 occupational performance problems for analysis and an additional 56 which had used half score ratings. Internal consistency reliability and construct validity were evaluated using Cronbach alpha statistic. Proxy views explored content validity. Responsiveness was evaluated using pre-post intervention scores and a comparison with Goal Attainment Scaling scores which were assumed to be a suitable benchmark measure. The effect of half scores was assessed by two-sample t-tests.

Results. The COPM adaptations did not have a negative impact on internal consistency reliability as this was acceptable for performance (0.73) and satisfaction (0.83). The high Cronbach alpha scores indicated good construct validity. Content of occupations and rating approach was considered valid by proxies. Use of half scores did not result in significantly different performance ratings, but mean satisfaction ratings were significantly higher when half scores were used (p = 0.0001). This suggests that half scores may provide more precise proxy satisfaction ratings, but at the cost of rigour as internal consistency with satisfaction half scores was lower (0.63 vs. 0.82). Responsiveness to change in clinical status was demonstrated by significant pre-post scores and moderate correlations with goal attainment scores.

Conclusion. The adapted COPM is a psychometrically robust tool and the use of half scores is not recommended.     

Physiotherapy in Afghanistan: an analysis of current challenges

Introduction. Afghanistan has high levels of disability due to prolonged conflict. An important part of the reconstruction process in Afghanistan is strengthening health service capacity and, within this, rehabilitation services.

Aims: To identify training needs of, and key issues affecting, Afghan physiotherapists.

Methods. 20 interviews and clinical accompaniment of 15 physiotherapists/physiotherapy assistants (APA) carried out in the second quarter of 2003. Analysis was using a grounded theory approach.

Results. Five themes emerged: (1) Low professional profile of physiotherapy; (2) Difficult working conditions; (3) Difficulty identifying personal training needs; (4) Difficulty with clinical reasoning at undergraduate level; (5) Variable levels of clinical competence.

Discussion. Many of the challenges facing Afghan physiotherapists are not unique to Afghanistan but are exacerbated by a lack of government recognition of the profession. War has isolated Afghan physiotherapists from completed professional links and consequently the undergraduate curriculum had not matched developments in other comparable countries. This has contributed to the difficulties therapists' experience with current clinical reasoning and accessing new practice developments. Culture also influences attitudes towards training and has restricted female travel and access to education.

Conclusions. Core training needs include disability sensitization, reflective practice and clinical reasoning. The physiotherapy curriculum needs updating and links with ongoing research need to be established to keep abreast of new developments.     

Public health significance of the frailty index

Background. A quantifiable indicator of frailty would be very useful in assessing the health state of older populations, as well as enable the effect of interventions to be evaluated over time.

Methods. A total of 2032 people aged 70 years and over recruited by stratified random sampling, and information obtained regarding physical and functional health, and psychological factors. The frailty index (FI) was constructed from 62 variables. Associations between the FI, and changes in ADL score, mental score, and hospitalization days over a 10-year period were evaluated.

Results. For the baseline to 3-year changes, a 0.10 increase in baseline FI is accompanied by a 0.499-point faster drop in ADL score, a 0.223-point faster decline in mental score, and 4.57-day faster increase in hospital days. For 3 - 10-year changes, frailty was a significant predictor only of changes in mental score, with results indicating that, on average, each increase of 0.10 in the baseline frailty index was associated with 0.613-point drop in mental score during this period. Chronological age and frailty had differential associations with those changes.

Conclusion. The FI is a valid indicator of morbidity and requirement for health and social services for ageing populations.     

Functional outcome in patients with critical illness polyneuropathy

Purpose: To evaluate the functional outcome of intensive care patients with critical illness polyneuropathy (CIP), 6 and 12 months after the onset.

Methods: Design: A prospective observational cohort study and a cross-sectional study.

Setting: University hospital in the Netherlands.

Patients: Eight consecutive intensive care patients with CIP for the prospective study and eight patients diagnosed with CIP in the past 6 months for the cross-sectional study.

Main outcome measures: Functional outcome regarding body functions and structure, activities, participation and perceived quality of life.

Results: Nine patients (56%) died within one year. Functional outcome, participation and subjective health status in survivors varied widely at 6 and 12 months. After 12 months, physical functioning was improved in all patients. However activities related to mobility outdoors, autonomy, participation and quality of life were restricted in most patients.

Conclusions: The majority of survivors have persistent functional disabilities in activities, reduced quality of life and restrictions in autonomy and participation one year after the onset of CIP. Prolonged rehabilitation treatment is necessary for an increasing number of intensive care patients who develop CIP, in order to reduce handicaps and achieve optimal autonomy and social participation.     

Self-rated health as a predictor of return to work among employees on long-term sickness absence

Aims. The aim of the present study is to identify self-rated health predictors of return to work (RTW) within the study population as a whole as well as in three subgroups, namely musculoskeletal complaints, other physical health complaints, and psychological complaints.

Methods. The study was based on a sample of 862 employees on sickness absence (maximum duration of 12 weeks). The employees filled out a baseline questionnaire and were subsequently followed until the tenth month after listing sick. Cox proportional hazards regression analyses were used to identify determinants of RTW.

Results. For the study population as a whole type of complaint, earlier sickness absence, subjective severity of complaints and several RAND-36 subscales were predictive of RTW. Furthermore, the RAND-36 subscales physical functioning, physical role limitations, mental health, and health change were predictive of RTW among employees with musculoskeletal complaints. For employees with other physical health problems subjective severity of complaints and the RAND-36 subscales physical and social functioning, general health perception, and health change were associated with RTW. Finally, with regard to the group with psychological complaints the RAND-36 subscales mental health and general health perception predicted RTW.

Conclusion. Several aspects of self-rated health predict RTW for employees on long-term sickness absence. Variables related to functional status predict RTW for employees with physical complaints in contrast to psychological problems.     

Is social participation associated with quality of life of older adults with physical disabilities?

Purpose: To explore the relationships between subjective quality of life and social participation of older adults with physical disabilities.

Method: A cross-sectional design was used with a convenience sample of 46 people aged 60 to 90 living in the community. Subjective quality of life was estimated with the Quality of Life Index and social participation with the Assessment of Life Habits.

Results: Only a weak relationship was found between total scores of quality of life and social participation. Interpersonal relationships, responsibilities, fitness and recreation were the categories of social participation most associated with quality of life. Social roles were more associated with quality of life than daily activities. Finally, satisfaction with the accomplishment of life habits was also more associated with quality of life than the performance itself.

Conclusions: The importance of social participation in regard to the quality of life of older persons with physical disabilities living in the community is partially supported by these findings. Other studies are needed to clarify how social participation influences quality of life in this population.     

Perceptual-motor coordination in persons with mild intellectual disability

Background. There is limited experimental evidence to support the view that individuals with intellectual disabilities (ID) have a deficit in motor control. This work is a first attempt to evaluate their motor coordination.

Purpose. The study assessed the relationship between cognitive ability and sensorimotor integration. The clinical hypothesis is that adults with ID fall below non-ID adults in motor skills that involve hand-eye coordination.

Method. A group of 42 adults with ID (ID group) was compared to 48 age-matched typical adults (TA) using a mixed experimental design ('Task' as the within-subjects factor and 'Group' as the between-subjects factor). Participants performed the following tests twice: Box-and-Blocks, 25-Grooved-Pegboard, Stick Catching and overhead Beanbag-Throw. Pearson correlations and ANOVAs were used to test the hypothesis (p ≤ 0.05).

Results. As expected, TA outperformed the ID group in all tests regardless of the hand used during for the assessment. However, TA individuals scored significantly better with one hand (i.e., the preferred and dominant hand) as opposed to persons with ID, who exhibited no hand preference. Test-retest correlations among the first and second assessment scores yielded moderate-strong coefficients, depending on the type of test (Box-and-Blocks = 0.92 and 0.96, 25-Grooved-Pegboard = 0.69 and 0.83, Stick-Catching = 0.88 and 0.94, Beanbag-Throw = 0.58 and 0.91 for ID and TA, respectively).

Discussion. Difficulties in the integration of perceptual information into motor action may result in inadequate solutions to daily motor problems. As it stems from our results, intellectual disability relates to inability to integrate visual inputs and hand movements. In people with mild ID such inability is observed using both hands (i.e., they show no hand preferences). Poor perceptual-motor coordination might have a functional significance in that it may lead to exclusion from vocational and recreational activities, and a decreasing competence of ADL. Assessing coordination in adults with ID may contribute to understanding the nature of the ID condition and may encourage an early rehabilitation.     

Effectiveness of workplace rehabilitation interventions in the treatment of work-related low back pain: a systematic review

Purpose. A systematic review was conducted to evaluate the effectiveness of workplace rehabilitation interventions for injured workers with low back pain (LBP).

Method. MEDLINE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), EMBASE, and AMED (Allied and Complementary Medicine) were searched from 1982 to 2005 for peer-reviewed studies of rehabilitation interventions that were provided at the workplace to workers with musculoskeletal work-related LBP. Methodological quality appraisal and data extraction were conducted by five reviewers.

Results. Of a total of 1,224 articles that were identified by the search, 15 articles, consisting of 10 studies, were of sufficient quality to be included in the review. The best evidence was that clinical interventions with occupational interventions as well as early return to work/modified work interventions were effective in returning workers to work faster, reducing pain and disability, and decreasing the rate of back injuries. Ergonomic interventions also were found to be effective workplace interventions.

Conclusion. The need for further research in this area is necessary to reduce the burden of back pain on employees and their families, employers, and the health care system.
