摘要:

PurposeObjective measures of strength in children with cerebral palsy (CP) are needed to determine the effect that selective dorsal rhizotomy surgery (SDR) and subsequent rehabilitation have on muscle strength. This investigation quantified quadriceps and hamstring strength in children with CP pre-SDR and eight months post-SDR.MethodNineteen children with CP and 20 children without disabilities (WD group) were tested with an isokinetic dynamometer. The children performed a maximum concentric contraction of the quadriceps muscles as the dynamometer moved the knee from a flexed position to an extended position at 10 degrees per second. A maximum concentric contraction of the hamstring muscles was then performed as the knee was moved from extension to flexion. Four variables were recorded from the torque-angle data; peak extension and flexion torque and extension and flexion work.ResultsChildren with CP, both pre- and post-SDR were significantly weaker in all strength measures compared with the WD group. Children with CP post-SDR and rehabilitation had significantly greater peak torque and work values compared with their pre-SDR values. The results agreed with previous studies indicating that children with CP are weaker than their peers without disabilities. Previous studies on strength changes after SDR remain controversial.ConclusionsThe results of this study showed a significant increase in strength at the knee after rhizotomy and rehabilitation.

摘要:

PurposeThe Gross Motor Function Measure (GMFM) is a criterion-referenced evaluative measure designed to detect change over time for children diagnosed with cerebral palsy (CP). Reliability of this measure has not been tested for children with osteogenesis imperfecta (OI). The purpose of this study was to determine the intra- and interrater reliabilities of the GMFM for use with children diagnosed with OI.MethodOne physical therapist administered and scored the GMFM for 19 children with OI who were followed at the Shriners Hospital for Children. The assessments were videotaped, then viewed and scored by five physical therapists, including the author, at least six weeks later. Intra- and interrater reliabilities were assessed using intraclass correlation coefficients (ICCs). Kappa statistics were calculated for items demonstrating more disagreement than the majority.ResultsThe ICCs for intrarater reliability of the five dimensions and total score were 0.99. The ICCs for interrater reliability were 0.98 for the lying and rolling dimension and 0.99 for the other dimensions and total score. Kappa statistics for items demonstrating more disagreement than the majority ranged from 0.552 to 1.00.ConclusionsThis study provides evidence of the reliability of the GMFM for children with OI when scored by pediatric physical therapists familiar with the measure. The videotape provided a consistent situation because each therapist did not directly interact with each child, but rather rated a videotaped session of the child’s performance.

摘要:

PurposeThe purposes of this study were to 1) determine test-retest reliability of hand-held dynamometer measurements of right hip abductor and knee extensor muscle strength in children with Down syndrome (DS), 2) identify differences in isometric muscle strength between children with DS and peers who are developing typically, and 3) determine the relationship between various anthropometric and demographic variables and isometric muscle strength.MethodsSeventeen children with DS between the ages of seven and 15 years and a comparison group of 17 age- and gender-matched peers who were developing typically participated in the study. A hand-held dynamometer was used to measure peak force during maximal isometric right hip abduction and knee extension at two test sessions approximately one week apart. Peak torque values were calculated by multiplying peak force measurements by the appropriate segment lengths. Anthropometric measurements were obtained, and a questionnaire was used to measure habitual physical activity levels.ResultsTest-retest reliability was high, with intraclass correlation coefficients ranging from 0.89 to 0.95. Children with DS had significantly lower mean peak torque values for hip abduction and knee extension than children in the comparison group. Regression analyses indicated that weight, body mass index, height, activity level, and gender were significant predictors of peak torque production for the sample as a whole.ConclusionsHand-held dynamometry can be used to obtain reliable measurements of isometric muscle strength in children with DS. Anthropometric characteristics and activity levels may play a role in peak torque production in children with and without DS.

摘要:

PurposeOptimal management of children with developmental disorders, such as cerebral palsy (CP), requires detection at an early age. The purpose of this paper is to review the predictive value of various forms of traditional neonatal neurological examination and that of a new form of neuromotor assessment of young infants, based on the assessment of the quality of general movements (GMs).Summary of Key PointsThe technique of GM assessment is presented and the features of normal, mildly abnormal and definitely abnormal GMs discussed. Essential to GM assessment is the Gestalt evaluation of movement complexity and variation. The quality of GMs at two to four months postterm has been found to have the highest predictive value. The presence of definitely abnormal GMs at this age, ie, GMs devoid of complexity and variation, puts a child at very high risk for CP.ConclusionsThis implies that definitely abnormal GMs at two to four months are an indication for early physical therapy intervention.

摘要:

PurposeThe purpose of this study was to determine the interrater reliability of the active knee-extension test (AKET) using a stabilizing apparatus to measure hamstring length.MethodsOne hundred one subjects (53 girls, 48 boys) ranging in age from 10 to 13 years with no known neuromuscular problems participated. The AKET was performed with subjects lying supine with the hip flexed to 90 degrees with a stabilization device attached to a plinth. Next, subjects were instructed to actively extend the knee until the rater detected myoclonus. Then, the rater flexed the knee until myoclonus subsided and the knee angle was measured with a blinded goniometer. This procedure was repeated by each of three raters.ResultsData were analyzed using ICC (2,1) demonstrating good interrater reliability of 0.79.ConclusionOur results suggest that the AKET, when used with the stabilizing apparatus, demonstrates good interrater reliability for children aged 10 to 13 years.
