Purpose. This cross-sectional study investigates deficits and associations in muscle strength, 6-minute walking distance (6MWD), aerobic capacity (VO2peak), and physical activity (PA) in independent ambulatory children with lumbosacral spina bifida. Method. Twenty-tree children participated (13 boys, 10 girls). Mean age (SD): 10.4 (±3.1) years. Muscle strength (manual muscle testing and hand-held dynamometry), 6MWD, VO2peak (maximal exercise test on a treadmill), and PA (quantity and energy expenditure [EE]), were measured and compared with aged-matched reference values. Results. Strength of upper and lower extremity muscles, and VO2peak were significantly lower compared to reference values. Mean Z-scores ranged from -1.2 to -2.9 for muscle strength, and from -1.7 to -4.1 for VO2peak. EE ranged from 73 - 84% of predicted EE. 6MWD was significantly associated with muscle strength of hip abductors and foot dorsal flexors. VO2peak was significantly associated with strength of hip flexors, hip abductors, knee extensors, foot dorsal flexors, and calf muscles. Conclusions. These children have significantly reduced muscle strength, 6MWD, VO2peak and lower levels of PA, compared to reference values. VO2peak and 6MWD were significantly associated with muscle strength, especially with hip abductor and ankle muscles. Therefore, even in independent ambulating children training on endurance and muscle strength seems indicated.
Objective: To determine content validity of the Muscle Power Sprint Test (MPST) and construct validity and reliability of the MPST, 10x5 Meter Sprint Test (10x5MST), slalom test and one stroke push test (1SPT) in wheelchair-using youth with spina bifida (SB). Design: Clinimetric study Setting: Rehabilitation centers, SB outpatient services, private practices Participants: A convenience sample of 53 children (5-19 years, 32 boys / 21 girls) with SB who use a manual wheelchair. Participants were recruited in the Netherlands through rehabilitation centers, SB outpatient services, pediatric physical therapists and the BOSK (Association of and by parents of children, adolescents and adults with a disability). Interventions: Not applicable. Main Outcome Measures: Construct validity of the the MPST was determined by comparing results with the arm-cranking Wingate Anaerobic test (WAnT) using paired t-tests and Pearson Correlation Coefficients, while content validity was assessed using time based criteria for anaerobic testing . Construct validity of the 10x5MST, slalom test and 1SPT was analyzed by hypothesis testing using Pearson Correlation Coefficients and Multiple Regression. For reliability, Intra Class Correlation coefficients (ICC) and smallest detectable changes (SDC) were calculated. Results: For the MPST, mean exercise time of four sprints was 28.1 sec. (±6.6 sec.). Correlations between the MPST and WAnT were high (r>0.72, p<0.01). Excellent correlations were found between the 10x5MST and slalom test (r=0.93, p<0.01), while correlations between the10x5MST or slalom test and MPST and 1SPT were moderate (r=-0.56- -0.70; r=0.56, p<0.01). The 1SPT was explained for 38% by wheelchair mass (Beta -0.489) and total upper muscle strength (Beta 0.420). All ICCs were excellent (ICC>0.95) but the SDCs varied widely. Conclusions: The MPST, 10x5MST and slalom test are valid and reliable tests in wheelchair-using youth with SB for measuring respectively anaerobic performance or agility. For the 1SPT, both validity and reliability are questionable.
Kinderen met motorische beperkingen (bijv. door DCD, hersenbeschadiging of Spina Bifida) ervaren veel belemmeringen in schoolse participatie (schoolse taken), zoals schrijven, taal, rekenen, meespelen, zelfstandig aankleden, knippen, en gymmen. Zij kunnen moeilijker meedoen aan schoolse taken vanwege hun motorische onhandigheid, vaak gekoppeld aan gedragsproblematiek. Het rapport ‘Ketenafspraken zorg in en om school’ beveelt een integrale benadering en samenwerking aan tussen zorg en onderwijs om schoolse participatie van kinderen met een motorische beperking (en andere kinderen) te bevorderen. Het Partnering for Change model (P4C) wordt door deelnemers van de leergemeenschap Kind en Jeugd Zuyd gezien als een raamwerk dat kan helpen bij het vormgeven van de samenwerking tussen zorgprofessionals en leerkrachten. Over de toepasbaarheid van P4C in het Nederlandse onderwijs en de betekenis ervan voor de dagelijkse praktijk is nog weinig bekend. De basisschool de kleine Wereld zou een eerste verkenning willen doen met het P4C model om te bezien hoe hanteerbaar de aanpak is in de praktijk en welke meerwaarde het heeft voor verandering van competenties van zowel leerkrachten als ergotherapeuten en op de schoolse participatie van kinderen met en zonder beperkingen.
