“…The LSA has been characterized as a participation measure in the literature 13,27,28 and could fulfill a need for outcome measures appropriate for persons with SCI regardless of their means of mobility. 29 Life wheeled mobility, either manual (LSA = 46.99) 16 or power (LSA = 33), 14 but smaller than that reported for a population-based study of persons aged 15 to 90 years (LSA = 98.3). 30 Despite the younger age of our sample, their LSA scores were comparable to the average reported for community-dwelling older adults with a mean age of 75 years (64.1 ± 24.9).…”

“…8 The LSA was developed for community-dwelling older adults due to their risk of mobility disability, 6,7,10 but it has been increasingly utilized in other at-risk populations. [11][12][13][14] Persons with SCI are certainly at risk for mobility disability. Although the LSA has been examined in populations that included persons with SCI, 15,16 to our knowledge no investigations have examined the LSA in a population limited to SCI.…”

Objectives: To examine the Life Space Assessment (LSA) in persons with spinal cord injury (SCI), exploring its psychometric properties, differences between persons with cervical versus thoracolumbar injuries, and cutoff score differentiating a restricted from an unrestricted life space. Method: We conducted a test-retest reliability study in a community setting involving 50 persons with SCI (25 injured above C7, 25 injured below T1). Data were collected in 2 phone interviews approximately 9 days apart using the LSA. Results: Mean LSA scores were 66 ± 25 (n = 50): 62 ± 23 for the cervical group, and 70 ± 25 for the thoracolumbar group. Scores were not significantly different between phone interviews [t (49) = 0.379, p = .706] or between groups [t (48) = -1.214, p = .231]. Test-retest reliability intraclass correlation coefficient (ICC) was 0.876 (95% CI, 0.792-0.928). Spearman's rho correlations between the LSA and Reintegration to Normal Living Index total and subscores ranged from .509 to .538 (p < .001). LSA scores were normally distributed. The minimum detectable change was approximately 23 points. A cutoff score of 78.5 (sensitivity 76.9%, specificity 81.1%) differentiated between persons with a restricted from an unrestricted life space if equipment and personal assistance were not needed for mobility. If equipment was needed, the cutoff score was found to be 49 (sensitivity of 90%, specificity of 90%). Conclusions: The LSA is a reliable and valid measure of life space in persons with SCI and can be used to identify persons with a restricted life space who may be at increased risk of mobility disability.

Objectives-To test the hypothesis that powered wheelchair users who receive the Wheelchair Skills Training Program (WSTP) improve their wheelchair skills in comparison with a Control group that receives standard care. Our secondary objectives were to assess goal achievement, satisfaction with training, retention, injury rate, confidence with wheelchair use and participation. Design-Randomized controlled trial (RCT). Setting-Rehabilitation centers and communities.Participants-116 powered wheelchair users. Intervention-Five 30-minute WSTP training sessions.Main Outcome Measures-Assessments were done at baseline (T1), post-training (T2) and 3 months post-training (T3) using the Wheelchair Skills Test Questionnaire (WST-Q 4.1), Goal Attainment Score (GAS), Satisfaction Questionnaire, Injury Rate, Wheelchair Use Confidence Scale for Power Wheelchair Users (WheelCon) and Life Space Assessment (LSA).Results-There was no significant T2-T1 difference between the groups for WST-Q capacity scores (p = 0.600) but the difference for WST-Q performance scores was significant (p = 0.016) with a relative (T2/T1 x 100%) improvement of the median score for the Intervention group of 10.8%. The mean (SD) GAS for the Intervention group after training was 92.8% (11.4) and satisfaction with training was high. The WST-Q gain was not retained at T3. There was no clinically significant difference between the groups in injury rate and no statistically significant differences in WheelCon or LSA scores at T3.Conclusions-Powered wheelchair users who receive formal wheelchair skills training demonstrate modest transient post-training improvements in their WST-Q performance scores, they have substantial improvements on individualized goals and they are positive about training.

“…Preliminary evaluation of the measurement properties of measures included in the toolkit indicated that they all had good reliability (intraclass reliability coefficients >.78) and demonstrated construct validity (28,29). Previous research has found the Life Space Assessment has excellent measurement properties for power mobility users (30). All of the measures were available in French and English, except the Wheelchair Use Confidence Scale.…”

OBJECTIVES-To evaluate the relationship among the measures in a power wheelchair outcomes toolkit. DESIGN-We performed path analysis of cross-sectional data from self-report questionnaires and one objective measure. SETTING-Data were collected in six Canadian sites.PARTICIPANTS-A convenience sample of 128 power wheelchair users. The majority, 69 (53.9%), were female. Multiple sclerosis and spinal cord injury/disease were the most common diagnoses. RESULTS-Wheelchair confidence was independently associated with less difficulty with activity (β =0.08, 0.01

0.05) and participation (β=0.39, p<0.01), increased life space (β=0.09, p<0.03) and greater wheelchair skills (β=0.37, p<0.01) Less perceived difficulty with activity was independently associated with increased frequency of participation (β=0.30, p<0.01). Life space mobility was independently associated with increased frequency of participation ((β=0.31, p<0.01). Less difficulty with participation was independently associated with greater life-space mobility (β=0.32, p<0.01) and greater frequency of participation (β=0.13, p<0.01). INTERVENTIONS-NotCONCLUSION-This study provides empirical support for the measures included as part of the power wheelchair outcomes toolkit. They appear to provide complementary information on a variety of constructs related to power wheelchair use.
