    Blood pressure and circulatory relationships with physical activity level in young normotensive individuals: IPAQ validity and reliability considerations2011In: Clinical and experimental hypertension (1993, Print), ISSN 1064-1963, E-ISSN 1525-6006, Vol. 33, no 5, p. 345-353Article in journal (Refereed)
    Abstract [en]

    Physical activity (PA) reduces risk of cardiovascular diseases, including hypertension. However, the international physical activity questionnaire (IPAQ) relationships with blood pressure (BP) and flow (BF) and vascular resistance (VR) in healthy young individuals have not been studied. Therefore, BP, BF, and VR relationships with the IPAQ were evaluated in college normotensive students (18-23 yrs). Additionally, the IPAQ relationships with body fat (%BF), muscle mass (MM), body mass index (BMI), waist/hip (W/H) ratio, maximum walking distance in 6 min (6MWD), and handgrip strength (MHG) were examined to evaluate the questionnaire validity against fitness. Subsequently, the IPAQ was administered three times to examine its reliability. Walking, moderate, and total PAs correlated negatively with sysbolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) (range: r = -3 to -0.5, p < 0.05). Additionally, all BP measures were greater in least physically active individuals. In a subgroup of 42 students, IPAQ sitting time correlated with BF (r = -0.3) and VR (r = 0.4). The intraclass correlation coefficient (ICC) for walking, moderate, vigorous, and total PAs and sitting time/week were, 0.97, 0.96, 0.97, 0.97, and 0.96, respectively. The males scored greater vigorous PA (p = 0.001) than the females, while moderate, walking, and total PAs were the same (p > 0.05). Additionally, vigorous PA correlated with %BF (r = -0.2), MM (r = 0.3), MHG (r = 0.3), and 6MWD (r = 0.3) and total PA correlated with MM (r = 0.2), MHG (r =0.2), and 6MWD (r = 0.3). The IPAQ association with the circulatory measures demonstrates PA importance for controlling BP and adds clinical value to the IPAQ. Additionally, the IPAQ is reliable, can discriminate between populations, and reasonably valid against health-related fitness.

    Validity and test-retest reliability of Children's Hand-use Experience Questionnaire in children with unilateral cerebral palsy2016In: Developmental Medicine & Child Neurology, ISSN 0012-1622, E-ISSN 1469-8749, Vol. 58, no 7, p. 743-749Article in journal (Refereed)
    Abstract [en]

    Aim: To investigate the validity of the internet-based version of the Children's Hand-use Experience Questionnaire (CHEQ) by testing the new four-category rating scale, internal structure, and test-retest reliability.

    Method: Data were collected for 242 children with unilateral cerebral palsy (CP) (137 males and 105 females; mean age 9y 10mo, SD 3y 5mo, range 6-18y). Twenty children from the study sample (mean age 11y 8mo, SD 3y 10mo) participated in a retest within 7 to 14 days. Validity was tested by Rasch analysis based on a rating scale model and test-retest reliability by Kappa analysis and intraclass correlation coefficient (ICC).

    Results: The four-category rating scale was within recommended criteria for rating scale structure. One item was removed because of misfit. CHEQ showed good scale structure according to the criteria. The effective operational range was >90% for two of the CHEQ scales. Test-retest reliability for the three CHEQ scales was: grasp efficacy, ICC=0.91; time taken, ICC=0.88; and feeling bothered, ICC=0.91.

    Interpretation: The internet-based CHEQ with a four-category rating scale is valid and reliable for use in children with unilateral CP. Further studies are needed to investigate the validity of the internet-based version of CHEQ for children with upper limb reduction deficiency or obstetric brachial plexus palsy and the validity of the recommended improvements to the current version.

    The effect of insoles on foot pain and daily activities2014In: Prosthetics and orthotics international, ISSN 0309-3646, E-ISSN 1746-1553, Vol. 38, no 6, p. 474-480Article in journal (Other academic)
    Abstract [en]

    BACKGROUND:

    Foot pain decreases individuals' ability to perform daily activities. Insoles are often prescribed to reduce the pain which, in turn, may promote return to normal activities.

    OBJECTIVES:

    To evaluate the effects of insoles on foot pain and daily activities, and to investigate the relationship between individuals' satisfaction with insoles and actual use of them.

    STUDY DESIGN:

    A 4-week pre-post intervention follow-up.

    METHODS:

    Brief Pain Inventory, International Physical Activity Questionnaire and Lower Extremities Functional Status were used as outcome measures. Client Satisfaction with Device was used in the follow-up.

    RESULTS:

    A total of 67 participants answered the questionnaires (81% women). Overall, a reduction in Pain Severity (p = 0.002) and Pain Interference (p = 0.008) was shown. Secondary analyses revealed a significant effect only in women. No changes in daily activities (Walking, p = 0.867; Total Physical Activity, p = 0.842; Lower Extremities Functional Status, p = 0.939) could be seen. There was no relation between Client Satisfaction with Device measures and duration of insole use. A difference in sex was shown; women scored higher than men on Pain Severity.

    CONCLUSION:

    Insoles reduce pain and pain interference with daily activities for women with foot pain. Satisfaction with the insoles is not a predictor of actual insole use. The effect of insoles on activity performance needs further study.

    CLINICAL RELEVANCE:

    This study provides evidence for prescribing insoles to people with foot pain. Nonetheless, insoles are not enough to increase their physical activity level in the short term. Satisfaction with insoles and duration of use are not correlated and cannot be inferred from each other.

    The Ugandan version of the Pediatric Evaluation of Disability Inventory (PEDI-UG). Part II: Psychometric properties2018In: Child Care Health and Development, ISSN 0305-1862, E-ISSN 1365-2214, Vol. 44, no 4, p. 562-571Article in journal (Refereed)
    Abstract [en]

    Background: The Pediatric Evaluation of Disability Inventory (PEDI) has been recommended as a gold standard in paediatric rehabilitation. A Ugandan version of PEDI (PEDI-UG) has been developed by culturally adapting and translating the original PEDI. The aim of this study was to investigate the psychometric properties of the PEDI-UG in Ugandan children by testing the instrument's rating scale functioning, internal structure, and test-retest reliability.

    Methods: Two hundred forty-nine Ugandan children (125 girls) aged 6 months to 7.5 years (Mean = 3.4, SD = 1.9) with typical development were tested using the PEDI-UG. Forty-nine children were tested twice to assess test-retest reliability. Validity was investigated by Rasch analysis and reliability by intraclass correlation coefficient.

    Results: The PEDI-UG domains showed good unidimensionality based on principal component analysis of residuals. Most activities (95%) showed acceptable fit to the Rasch model. Six misfit items were deleted from the Functional Skills scales and one from the Caregiver Assistance scales. The category steps on the Caregiver Assistance scales' rating scale were reversed but functioned well when changed from a 6-point to 4-point rating scale. The reliability was excellent; intraclass correlation coefficient was 0.87-0.92 for the domains of the Functional Skills scales and 0.86-0.88 for the domains of the Caregiver Assistance scales.

    Conclusion: The PEDI-UG has good to excellent psychometric properties and provides a valid measure of the functional performance of typically developing children from the age of 6 months to 7.5 years in Uganda. Further analysis of all items, including misfit and deleted items, in children with functional disability is recommended.
