RESUMO
OBJECTIVES: To describe the clinical courses of positional preference and deformational plagiocephaly up to 6 months corrected age (CA) in infants born at gestational age <30 weeks or birth weight <1000 g, and to explore predictive factors for the persistence of these phenomena. STUDY DESIGN: A total of 120 infants were examined 3 times each. The presence of deformational plagiocephaly and a score of 0-6 on an asymmetry performance scale served as outcome measures at 6 months CA. Predictive factors were determined using regression analysis. RESULTS: The prevalence of a positional preference of the head was 65.8% (79 of 120) at term-equivalent age (TEA) and 36.7% (44 of 120) at 3 months CA and that of deformational plagiocephaly was 30% (36 of 120) at TEA and 50% (60 of 120) at 3 months CA. At 6 months CA, 15.8% of the infants (19 of 120) scored ≥ 2 of a possible 6 on the asymmetry performance scale and 23.3% (28 of 120) had deformational plagiocephaly. Sleeping in the supine position was predictive of an asymmetric motor performance at 6 months CA. Chronic lung disease and/or slow gross motor maturation at 3 months CA predicted the persistence of deformational plagiocephaly. CONCLUSION: Infants born very preterm may develop deformational plagiocephaly. A positional preference of the head at TEA seems to be a normal aspect of these infants' motor repertoire, with limited ability to predict persistence of an asymmetric motor performance. The decreased prevalence of deformational plagiocephaly between 3 and 6 months CA indicates an optimistic course. Infants with a history of chronic lung disease and/or slow gross motor maturation merit timely intervention.

PURPOSE: The International Classification of Human Functioning Disability and Health (ICF) provides insight into functional health status in patients with whiplash-associated disorders (WAD). In the assessment of functional limitations in patients with WAD, there are several condition-specific questionnaires available. Estimation of the true relationship between the separate constructs of the ICF is only possible if the items of the salient questionnaires measure exactly the constructs of interest, while not simultaneously measuring other constructs of the model. This study aimed to develop a condition specific and clinically relevant and usable instrument for patients with WAD that measures activity limitations and participation restrictions, as defined by the ICF framework. METHODS: Item generation consisted of (1) a semi-structured interview which was conducted among 69 WAD patients; (2) a Delphi study involving 13 health professionals experienced in the assessment of patients with WAD; (3) a literature search for items from self-assessment questionnaires for neck pain. RESULTS: A 35-item condition-specific self-assessment questionnaire for patients with WAD was developed. This new questionnaire measures purely activity limitations and participation restrictions according to the ICF and is based on patients' opinions and expert opinions. CONCLUSION: The whiplash activity and participation list tends to measure clinically relevant activity limitations and participation restrictions in WAD patients.

AIM: To explore whether active head lifting from supine (AHLS) in early infancy is associated with cognitive outcome in the second year of life. METHOD: The presence of AHLS was always recorded in the notes of infants admitted to our tertiary neonatal intensive care unit. Random sampling was used to pair infants with AHLS with two comparison infants without AHLS whose sex, gestational age, birth year (1993-2009), time of assessment, and developmental test (Griffiths Mental Development Scales, Mental Scale of the Bayley Scales of Infant Development-II, or cognitive subtest of the Bayley Scales of Infant and Toddler Development-III) were comparable. Brain injury identified from neonatal cranial ultrasound scans was classified as no - mild or moderate - severe. Z-scores of cognitive test outcomes were calculated for multivariable analysis. RESULTS: Eighty-seven preterm (34 males, 53 females) and 40 term (17 males, 23 females) infants with AHLS were identified. AHLS was documented at a mean (corrected) age of 7.0 (SD 1.7) and 8.1 (SD 2.2) months respectively. The cognitive assessments were performed at a mean corrected age of 15.7 (SD 1.7) and 23.9 (SD 1.6) months in preterm infants, and 19.1 (SD 2.3) months in term infants. The mean cognitive outcome of preterm and term infants with AHLS was lower than that of infants without AHLS (p=0.002 and p=0.004 respectively). This remained after excluding infants with cerebral palsy with matching comparison infants (p=0.001 in preterm and p=0.001 in term infants). The mean difference was highest (1.35SD) between term male infants and comparison infants (p=0.001). INTERPRETATION: AHLS is associated with a less favourable cognitive outcome in the second year of life in preterm as well as in term-born infants than in comparison infants.

OBJECTIVE: To examine incidence and severity of cerebral palsy (CP), and associated factors among preterm survivors (gestational age <34 weeks), admitted to a neonatal intensive care unit from 1990-2005. STUDY DESIGN: Eighteen antenatal, perinatal and postnatal factors were analyzed. The cohort was divided in four birth periods: 1990-1993 (n=661), 1994-1997 (n=726), 1998-2001 (n=723), and 2002-2005 (n=850). The Gross Motor Function Classification System was used as primary outcome measure (mean age: 32.9 ± 5.3 months). Logistic regression analyses were used. RESULTS: CP incidence decreased from 6.5% in period I, to 2.6%, 2.9% and 2.2% (P<.001) in period II-IV, respectively. Simultaneously, cystic periventricular leukomalacia (c-PVL) decreased from 3.3% in period I to 1.3% in period IV (P=.004). Within the total cohort (n=3287), c-PVL grade III decreased from 2.3% in period I to 0.2% in period IV (P=.003). The number of children with Gross Motor Function Classification System levels III-V decreased from period I to IV (P=.035). Independent risk factors for CP were c-PVL and severe intraventricular hemorrhage, whereas antenatal antibiotics, presence of an arterial line, Caesarean section, and gestational age were independent protective factors. CONCLUSION: CP incidence and severity decreased from 1990-1993 onward, which could be attributed to a reduction of 93% in severe c-PVL.

PURPOSE: To study whether peak oxygen uptake ((Equation is included in full-text article VO2 peak), attained in traditional cardiopulmonary exercise testing (CPET) in adolescents with cystic fibrosis (CF), could be verified by a supramaximal exercise test. METHODS: Sixteen adolescents with CF (forced expiratory volume in 1 second as % of predicted [range, 45%-117%]) volunteered and successively performed CPET and a supramaximal test (Steep Ramp Test [SRT] protocol). RESULTS: Cardiopulmonary exercise testing and the SRT resulted in comparable cardiorespiratory peak values. We found no significant difference in oxygen uptake ((Equation is included in full-text article VO2 peak/kg) between CPET and the SRT (38.9 ± 7.4 and 38.8 ± 8.5 mL min kg, respectively; P = .81). We found no systemic bias for CPET and SRT measurements of (Equation is included in full-text article VO2 peak/kg and no differences between CPET and SRT (Equation is included in full-text article VO2 peak values within and between the maximal and non-maximal effort groups (P > .4). CONCLUSION: The (Equation is included in full-text article VO2 peak measured in CPET seems to reflect the true (Equation is included in full-text article.)O2 peak in adolescents with CF.

The primary purpose of this study was to examine whether grip strength is related to total muscle strength in children, adolescents, and young adults. The second purpose was to provide reference charts for grip strength, which could be used in the clinical and research setting. This cross-sectional study was performed at primary and secondary schools and the University of Applied Sciences. Three hundred and eighty-four healthy Dutch children, adolescents, and young adults at the age of 8 to 20 years participated. Isometric muscle strength was measured with a handheld dynamometer of four muscle groups (shoulder abductors, grip strength, hip flexors, and ankle dorsiflexors). Total muscle strength was a summing up of shoulder abductors, hip flexors, and ankle dorsiflexors. All physical therapists participated in a reliability study. The study was started when intratester and intertester reliability was high (Pearson correlation coefficient >0.8). Grip strength was strongly correlated with total muscle strength, with correlation coefficients between 0.736 and 0.890 (p < 0.01). However, the correlation was weaker when controlled for weight (0.485-0.564, p < 0.01). Grip strength is related to total muscle strength. This indicates, in the clinical setting, that grip strength can be used as a tool to have a rapid indication of someone's general muscle strength. The developed reference charts are suitable for evaluating muscle strength in children, adolescents, and young adults in clinical and research settings.

OBJECTIVE: The aim of this study was to develop a 12-week exercise training program (comprising aerobic and strength exercises), and to study the feasibility and efficacy of this exercise program in children who survived acute lymphoblastic leukemia. SAMPLE AND METHODS: A 12-week exercise program was developed and tested for feasibility in nine children who survived cancer. RESULTS: From the 16 eligible children for the intervention, 9 participated, while 4 were able to complete the entire program. Feasibility of the program was scored by five children, two of them reported the program as being too demanding. The participating physiotherapists were satisfied with training methodology and training progress. The efficacy of the program on muscle strength, exercise capacity, functional mobility and fatigue showed no significant differences between pre and post training. CONCLUSION: In designing a community-based exercise training program, not only the stage of the disease needs to be considered, but more so the age of the children, the variety of exercises, the location of implementation and even more importantly the views and motivation of the parents concerning the execution of an exercise training program. A careful balance between these parameters could lead to a greater adherence and by that, to a better outcome of these programs.

The stability of the Gross Motor Function Classification System (GMFCS) over time is described in 77 infants (41 boys, 36 girls) with cerebral palsy (CP; mean age 19.4mo [SD 1.6 mo]; 27 unilateral spastic, 42 bilateral spastic, eight dyskinetic type) and in the same children at follow-up at age 2 to 4 years. The overall level of agreement over time (linear weighted kappa) was 0.70 (95% confidence interval [CI] 0.61-0.79). The overall percentage of children whose GMFCS level changed one or two levels was 42%, of which the majority were reclassified to a less functional level (McNemar's Chi(2) test p=0.11). The chance that children initially classified in the combination of GMFCS Levels I, II, and III would subsequently be classified in the same level in early childhood was 96% (positive predictive value [PPV] 0.96, 95% CI 0.85-0.99), whereas the PPV for the combination of Levels I and II was 0.88, 95% CI 0.70-0.96. These findings indicate that GMFCS classification in infants is less precise than classification over time in older children. In conclusion, children can be classified by the GMFCS early on, but there is a need for reclassification at age 2 or older as more clinical information becomes available.

AIM: To examine the relation between physical fitness and gross motor capacity in children with cerebral palsy (CP) who were classified in Gross Motor Function Classification System levels I or II. METHOD: In total, 68 children with CP (mean age 12y 1mo, SD 2y 8mo; 44 males, 24 females; 45 classified as having spastic unilateral CP, 23 as having spastic bilateral CP) participated in this study. All participants performed a maximal aerobic exercise test (10m Shuttle Run Test), a short-term muscle power test (Muscle Power Sprint Test), an agility test (10x5m sprint test), and a functional muscle strength test (30s repetition maximum) within 2 weeks. Gross motor capacity was concurrently assessed using dimensions D (standing) and E (walking, running, and jumping) of the 88-item version of the Gross Motor Function Measure (GMFM). RESULTS: No relation between aerobic capacity, body mass index, and dimensions D and E of the GMFM was found. The correlations between short-term muscle power, agility, functional muscle strength, and dimensions D and E of the GMFM were moderate to high (r approximately 0.6-0.7). INTERPRETATION: The relations found between short-term muscle power, agility, functional muscle strength, and gross motor capacity indicate the importance of these components of physical fitness, and may direct specific interventions to maximize gross motor capacity in children and adolescents with CP.

PURPOSE: This cross-sectional study investigates deficits and associations in muscle strength, 6-minute walking distance (6MWD), aerobic capacity (VO(2peak)), 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, VO(2peak) (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 VO(2peak) 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. VO(2peak) 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, VO(2peak) and lower levels of PA, compared to reference values. VO(2peak) 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.

PURPOSE: The aim of this study was to investigate whether muscle strength and functional exercise capacity (FEC) influence motor performance in children with generalized joint hypermobility. METHODS: Forty-one children (mean age: 8.1 years) with symptomatic generalized hypermobility were included. Motor performance was assessed using the Körperkoordinationstest für Kinder (KTK) and the Movement Assessment Battery for Children. Muscle strength and FEC were measured with a handheld dynamometer and the 6-minute walk test. RESULTS: Only muscle strength was significantly positively associated with motor performance on the KTK. FEC was significantly decreased. Children's scores on the KTK were significantly lower (p < 0.001) compared with scores on the Movement Assessment Battery for Children. CONCLUSIONS: The KTK is a more sensitive tool for detecting motor problems in children with generalized joint hypermobility, but is not associated with FEC. Along with the KTK, the 6-minute walk test can be used to independently assess and evaluate FEC.

OBJECTIVE: To study the effects of a physical training program on exercise capacity, muscle force, and subjective fatigue levels in patients with mild to moderate forms of osteogenesis imperfecta (OI). STUDY DESIGN: Thirty-four children with OI type I or IV were randomly assigned to either a 12-week graded exercise program or care as usual for 3 months. Exercise capacity and muscle force were studied; subjective fatigue, perceived competence, and health-related quality of life were secondary outcomes. All outcomes were measured at baseline (T = 0), after intervention (T = 1), and after 6 and 9 months (T = 2 and T = 3, respectively). RESULTS: After intervention (T = 1), peak oxygen consumption (VO2peak), relative VO2peak (VO2peak/kg), maximal working capacity (Wmax), and muscle force were significantly improved (17%, 18%, 10%, and 12%, respectively) compared with control values. Subjective fatigue decreased borderline statistically significantly. Follow-up at T = 2 showed a significant decrease of the improvements measured at T = 1 of VO2peak, but VO2peak/kg, Wmax, and subjective fatigue showed no significant difference. At T = 3, we found a further decrease of the gained improvements. CONCLUSION: A supervised training program can improve aerobic capacity and muscle force and reduces levels of subjective fatigue in children with OI type I and IV in a safe and effective manner.

OBJECTIVE: To determine whether aerobic capacity is normal in boys with different types of hemophilia compared with healthy peers and whether the level of aerobic capacity correlates with the amount of physical activity, joint health status, muscle strength, and anthropometrics. STUDY DESIGN: 47 patients (mean [SD] age, 12.9 [3.2] years; age range, 8.2-17.4 years) from the "Van Creveldkliniek" of the University Medical Center Utrecht, participated. Anthropometry, muscle strength, joint impairment, functional ability, and aerobic capacity were measured. The amount of energy expenditure during daily living was assessed. RESULTS: All boys were able to perform at maximal or near-maximal level on exercise tests, and none of them reported bleeds or other adverse events. Relative peak oxygen, peak heart rate, and peak working capacity were significantly lower compared with healthy control subjects. 30% had Z-scores >2 for weight. Total muscle strength was normal, and almost no joint impairment and no decrease in functional ability were found. CONCLUSION: The aerobic capacity of children with hemophilia is still lower than the normal population, whereas their overall muscle strength is comparable with healthy peers. The functional ability does not differ from healthy peers, and joint health status showed very minor impairments. A substantial proportion of Dutch children with hemophilia was overweight, without showing a reduction in the amount of self-reported physical activities.

PURPOSE: To evaluate the intertester reliability of two methods for measuring lower-limb strength in children with cerebral palsy (CP). METHOD: Twenty-five subjects with CP (7-17 years of age) participated in this study. Lower-limb muscle strength was measured on 2 occasions using a Hand-held Dynamometer (HHD; break-method and make-method) and a 30-sec Repetition Maximum (RM) during three functional strength tests for the lower extremities. Reliability was measured using the intraclass correlation coefficients (ICCs), the standard error of measurement (SEM) and the coefficient of variation (CV). RESULTS: The intertester reliability of strength measurement using a HHD was questionable with ICC values ranging from 0.42-0.73 for the break-method, and from 0.49-0.82 for the make-method. The SEM and CV (%) values ranged from 27.9-58.9 and 22.2-35.3% for the break-method, and from 30.6-52.7 and 16.2-56.2% for make-method. The intertester reliability of strength measurement using the 30-sec RM was acceptable with ICC values ranging from 0.91 -0.96, and SEM and CV (%) values ranging from 1.1-2.6 and 10.9-39.9% for the functional exercises. CONCLUSION: The intertester reliability of measuring muscle strength of the lower extremities using a hand-held dynamometer is questionable. The intertester reliability of the 30-sec RM for the lower extremity is acceptable.

OBJECTIVE: To study in children with achondroplasia the response to exercise and muscle strength compared with healthy peers and to describe the relation between exercise capacity, anthropometric factors, and physical activity. STUDY DESIGN: Patients (7 boys and 10 girls; mean age, 11.8 +/- 3.3 years) with achondroplasia performed a maximal treadmill exercise test. Anthropometric variables and muscle strength were measured and compared with the general population. The level of everyday physical activity was measured by using a diary. Functional ability was measured by using the Activity Scale for Kids. RESULTS: The exercise capacity of the children with achondroplasia was significantly reduced compared with reference values. All anthropometrical measurements differed significantly from reference values. There was a decrease in muscle strength in almost all muscle groups. We found a reduced physical activity level and impairments in functional ability. CONCLUSIONS: Cardiopulmonary exercise capacity and muscle strength in children with achondroplasia was reduced compared with reference values. Children with achondroplasia have a unique response to exercise. Clinicians should take these characteristic differences into account when the exercise capacity of subjects with achondroplasia is being tested.

Although patients with Chronic Idiopathic Axonal Polyneuropathy (CIAP) report a slow deterioration of sensory and motor functions, the impact of this deterioration on daily functioning has not yet been investigated in detail. The first aim of this cross-sectional study involving 56 patients with CIAP was, therefore, to assess patients' functioning with use of the International Classification of Functioning, Disability and Health (ICF). The second aim was to find determinants of walking ability, dexterity, and autonomy. Fatigue and limited walking ability were present in most patients and differed considerably. In regression models, age, muscle strength, and fatigue together explained 63% of the variance in walking ability, which by itself explained almost 50% of the variance in patients' autonomy indoors and outdoors (42% and 49%, respectively). Muscle strength and sensory function scores together explained 30% of the variance in dexterity scores, which in turn explained only 13% of the variance in autonomy indoors. The diminished autonomy of patients with CIAP might be improved by reducing fatigue, by means of training, and by improving walking ability.

BACKGROUND AND AIMS: Children with DCD have lower self-perceptions and are less physically active than typically developing children. The aim of this quasi-experimental study was to investigate whether an integrated perceived competence and motor intervention affects DCD children's motor performance, self-perceptions, and physical activity compared with a motor intervention only. METHODS AND PROCEDURES: The intervention group consisted of 20 children and the care-as-usual group consisted of 11 children, all aged 7-10 years. The perceived competence component of the intervention focused primarily on providing positive, specific, and progress feedback to enhance self-perceptions. We assessed children at baseline, after 12 treatment sessions (trial end-point), and at 3-month follow-up. OUTCOMES AND RESULTS: Mixed linear models revealed no differences between the intervention and the care-as-usual group on any of the outcome measures. Children improved their motor performance and increased their perceived athletic competence, global self-esteem, and perceived motor competence after 12 treatment sessions. This improvement was maintained at 3-month follow-up. Motor task values and physical activity remained unchanged for all children. CONCLUSIONS AND IMPLICATIONS: A perceived competence and motor intervention is as effective as care-as-usual in children with DCD. Future research should focus on improving physical activity in children with DCD. WHAT THIS PAPER ADDS: This is the first study that has investigated the effect of an integrated perceived competence and motor intervention (intervention group) on motor performance, self-perceptions, and physical activity compared with a motor intervention (care-as-usual group) in children with DCD. We made the perceived competence component explicit by providing positive, specific, and progress feedback to enhance children's self-perceptions. Also, this is one of the first studies that has investigated the effect after both 12 treatment sessions (trial end-point) and after 3 months of no intervention (3-month follow-up). We found no differences between the intervention and the care-as-usual group, but children improved their motor performance and increased (most) of their self-perceptions after 12 treatment sessions, while physical activity remained the same. The improvement was still present at the 3-month follow-up. We also benchmarked our results about self-perceptions and physical activity to a group of typically developing children. Self-perceptions in children with DCD had improved to the level of typically developing children after 12 treatment sessions, but their physical activity levels remained significantly lower. This result was the same at the 3-month follow-up, except for perceived athletic competence, which was lower in children with DCD at the 3-month follow-up. In accordance with previous intervention studies that have investigated children with DCD, we found large intra-group variability in the change in motor performance and self-perceptions in children with DCD. We argue that we need to better understand why some children with DCD improve and others do not after a motor intervention.

BACKGROUND AND PURPOSE: The purpose of this study was to examine the reliability and validity of data obtained with 2 newly developed shuttle run tests (SRT-I and SRT-II) to measure aerobic power in children with cerebral palsy (CP) who were classified at level I or II on the Gross Motor Function Classification System (GMFCS). The SRT-I was developed for children at GMFCS level I, and the SRT-II was developed for children at GMFCS level II. SUBJECTS: Twenty-five children and adolescents with CP (10 female, 15 male; mean age = 11.9 years, SD = 2.9), classified at GMFCS level I (n = 14) or level II (n = 11), participated in the study. METHODS: To assess test-retest reliability of data for the 10-m shuttle run tests, the subjects performed the same test within 2 weeks. To examine validity, the shuttle run tests were compared with a GMFCS level-based treadmill test designed to measure peak oxygen uptake. RESULTS: Statistical analyses revealed test-retest reliability for exercise time (number of levels completed) (intraclass correlation coefficients of .97 for the SRT-I and .99 for the SRT-II) and reliability for peak heart rate attained during the final level (intraclass correlation coefficients of .87 for the SRT-I and .94 for the SRT-II). High correlations were found for the relationship between data for both shuttle run tests and data for the treadmill test (r = .96 for both). DISCUSSION AND CONCLUSION: The results suggest that both 10-m shuttle run tests yield reliable and valid data. Moreover, the shuttle run tests have advantages over a treadmill test for children with CP who are able to walk and run (GMFCS level I or II).

CONTEXT: Postoperative pulmonary complications (PPCs) after coronary artery bypass graft (CABG) surgery are a major source of morbidity and mortality, and increase length of hospital stay and resource utilization. The prehospitalization period before CABG surgery may be used to improve a patient's pulmonary condition. The efficacy of preoperative inspiratory muscle training (IMT) in reducing the incidence of PPCs in high-risk patients undergoing CABG surgery has not yet been determined. OBJECTIVE: To evaluate the prophylactic efficacy of preoperative IMT on the incidence of PPCs in high-risk patients scheduled for elective CABG surgery. DESIGN, SETTING, AND PATIENTS: A single-blind, randomized clinical trial conducted at the University Medical Center Utrecht, Utrecht, the Netherlands, with enrollment between July 2002 and August 2005. Of 655 patients referred for elective CABG surgery, 299 (45.6%) met criteria for high risk of developing PPCs, of whom 279 were enrolled and followed up until discharge from hospital. INTERVENTION: Patients were randomly assigned to receive either preoperative IMT (n = 140) or usual care (n = 139). Both groups received the same postoperative physical therapy. MAIN OUTCOME MEASURES: Incidence of PPCs, especially pneumonia, and duration of postoperative hospitalization. RESULTS: Both groups were comparable at baseline. After CABG surgery, PPCs were present in 25 (18.0%) of 139 patients in the IMT group and 48 (35.0%) of 137 patients in the usual care group (odds ratio [OR], 0.52; 95% confidence interval [CI], 0.30-0.92). Pneumonia occurred in 9 (6.5%) of 139 patients in the IMT group and in 22 (16.1%) of 137 patients in the usual care group (OR, 0.40; 95% CI, 0.19-0.84). Median duration of postoperative hospitalization was 7 days (range, 5-41 days) in the IMT group vs 8 days (range, 6-70 days) in the usual care group by Mann-Whitney U statistic (z = -2.42; P = .02). CONCLUSION: Preoperative IMT reduced the incidence of PPCs and duration of postoperative hospitalization in patients at high risk of developing a pulmonary complication undergoing CABG surgery.
