* Does Daily Physical Activity Level Determine the Physical Efficiency of Children After Treatment of Leukemia?
- The aim of the study was to assess daily physical activity level and its influence on the physical efficiency of children after the treatment of leukemia. The study was comprised of 34 children (23 boys and 11 girls) after the treatment of acute lymphoblastic leukemia or myeloid leukemia (mean age of 11.29 ± 2.81 years, mean body height of 146.88 ± 16.11 cm, and mean body weight of 43.68 ± 13.93 kg). The mean time since treatment completion was 3.09 ± 1.80 years. The level of physical activity was assessed with the Health Behavior in School-Aged Children questionnaire (HBSC). Physical efficiency was assessed based on the palant ball throw (assessment of strength, coordination, and upper limb speed), the long jump (assessment of jumping ability, speed and coordination) and the 60 m run (assessment of speed). Measurements of motor skills were normalized, classified according to age and sex, and converted into grades. The mean values obtained in the run and the ball throw showed low pass grades in the study group. In the case of the long jump, satisfactory grades were obtained. A correlation of r = 0.512 was found between vigorous physical activity (HBSC 3) and the grade in the run. A correlation of r = -0.437 was observed between the duration of computer use in leisure time (HBSC 6) and the grade in the long jump, whereas correlations of r = -0.482 and -0.485 were noted between the number hours per week spent on games (HBSC 5) and the duration of computer use in leisure time (HBSC 6) and the grade obtained in the ball throw, respectively. In addition, different levels of physical activity and physical efficiency were demonstrated depending on the time elapsed since treatment completion. Supervised programs promoting daily physical activity should include children after the treatment of leukemia. These programs should also be aimed at improving their physical efficiency.
* Using Rasch and factor analysis to develop a Proxy-Reported health state classification (descriptive) system for Cerebral Palsy.
- Purpose: The Cerebral Palsy quality of life instrument is a well-known health-related quality of life measure for children with Cerebral Palsy. Due to its length it is not suitable as the basis of a preference-based instrument. The aim of this study is to develop a short version of the Cerebral Palsy quality of life instrument that can subsequently be scored as a multi-attribute utility instrument through assigning preference-based values.Methods: A sample of 473 participants who have a child with Cerebral Palsy completed the Cerebral Palsy quality of life instrument(proxy-version) instrument. After deleting questions related only to the proxy, the dimensional structure was obtained using exploratory factor analysis. Extended Rasch analysis was then undertaken to test the psychometric performance of items and select the best item to represent each dimension. Expert opinion was sought to confirm the dimensions and items.Results: A six-dimension classification system was identified, in which four domains were extracted from the factor analysis. Following expert opinion, two other domains were also added, as these were considered to have significant impact on health-related quality of life in children with Cerebral Palsy.Conclusions: The combination of Factor and Rasch analysis along with consultation with patients, clinicians and experts in health-related quality-of-life instrument development, has resulted in a short version of the Cerebral Palsy quality of life instrument.IMPLICATION FOR REHABILITATIONThis study provides the first classification system for children with Cerebral Palsy.The Cerebral Palsy-six dimension (CP-6D) survey, which is a short version of Cerebral Palsy Quality Of Life instrument, can be timesaving when measuring quality of life in children with Cerebral Palsy.The short version (CP-6D) can be used in preference based measurement and generate quality adjusted life years for children with Cerebral Palsy.
