摘要:

PurposeThe purpose of this study was to develop and test the reliability and validity of a pilot survey of backpack use and neck and back pain in seventh and eighth graders.MethodsA survey was developed on the basis of literature review and expert input. The survey was administered to 69 seventh and eighth graders. One week later, the survey was readministered to 20 students. Internal consistency was assessed with Cronbach's &agr; coefficient. Test-retest reliability was examined by calculating the percentage of agreement and &kgr; values. Construct validity was assessed by determining whether hypothesized age and gender differences in responses were present.ResultsThe internal consistency of responses related to neck or back pain and backpack use was high, with Cronbach's &agr; coefficients of 0.83 and 0.85, respectively. Percentage of agreement for the neck and back pain responses ranged from 45% to 100% (mean [SD] = 77% [15%]). The &kgr; coefficients ranged from 0.10 to 1.00 (mean [SD] = 0.54 [0.23]). Percentage of agreement for backpack use questions ranged from 60% to 100% (mean [SD] = 84% [9%]). The &kgr; coefficients ranged from 0.14 to 1.00 (mean [SD] = 0.59 [0.20]). Construct validity of the survey was partially supported. Age and gender differences in neck and back pain varied with the question. Age and gender differences in backpack use were consistent and as hypothesized.ConclusionsOur findings provide preliminary support for the use of this survey with seventh and eighth graders. Additional testing is needed to assess reliability and validity in a larger, more diverse sample.

摘要:

PurposeThe purpose of this study was to examine the heart rate and walking velocity of children with low and midlumbar myelomeningocele (MMC) using two types of orthoses.MethodsEight children with low and midlumbar myelomeningocele (mean age = 10.7 years) participated in the study. A clinical examination of muscle strength in the lower limbs was performed, and level of functional ambulation was defined. Weight and height were documented, and body mass index was calculated. Heart rate was recorded by a transmitter detecting heart beats, and walking time was registered as the children walked as far as possible along a straight corridor of 102 meters at a self-selected velocity. Two orthosis types were tested, each three times.ResultsAll children showed higher heart rate than peers who were nondisabled. No steady-state heart rate level that could be used as a basis for calculating physiological cost index was achieved in any subject. In this study group, no difference was seen in heart rate trends with respect to the two tested orthoses. The children who were household ambulators, all with weaker hip abductors and hip extensors, walked with lower velocity than those who were community ambulators (all with stronger hip muscles). The children in the former group also walked significantly shorter distances, however, with similar heart rate.ConclusionsPausing when the heart rate reaches a strenuous activity level is interpreted as a solution to maintain functional walking by keeping the heart rate and thus the energy expenditure at a comfortable level.

摘要:

PurposeThis study compared the effectiveness of a CD-ROM self-study program with a workshop and scoring videotapes as methods for learning to score the Test of Infant Motor Performance.MethodsTwenty-three therapists participated. Subjects in the videotape group (N = 11) were trained by attending a four-hour workshop and scoring 14 training videotapes, whereas subjects in the CD-ROM group (N = 12) used a CD-ROM self-study program. All subjects scored four videotapes for rater reliability analysis after completing the training procedures. Studentttests were used to compare the means of the two groups on three reliability variables (percentage of aberrant ratings, rater consistency, and rater severity) obtained from Rasch analysis and to compare average time spent on learning.ResultsSeven therapists (58.3%) in the CD-ROM group and six (54.5%) in the videotape group met the preestablished criteria for achieving satisfactory rater reliability. No statistically significant difference between learning methods was found in percentage of aberrant ratings or rater consistency, but raters in the videotape group were more lenient in scoring than those in the CD-ROM group. The CD-ROM group spent significantly less time learning than the videotape group.ConclusionsTherapists can learn how to score the Test of Infant Motor Performance by using the CD-ROM self-study program in about half the time and with similar reliability when compared with a workshop and videotape practice training procedure. About 40% of therapists will need more training to attain acceptable rater reliability.

摘要:

PurposeMost research details the influence of orthoses on impairments in children with cerebral palsy. The purpose of this study was to determine the effect of orthoses on multiple tests of function.MethodsThe researchers used the Standardized Walking Obstacle Course (SWOC), Pediatric Balance Scale (PBS), performance on individualized goals related upright function, and self-reports of comfort and stability with and without orthoses to examine 28 children (5.4–19.1 years of age) with cerebral palsy.ResultsNo significant differences were found in performance on the SWOC and PBS with and without orthoses. Only 18% of the children performed better on an individualized goal with their orthoses, but 48% of the children reported more feelings of comfort and stability while wearing orthoses.ConclusionsResults of this study bring into question the use of orthoses to improve functional balance and ambulation in children with cerebral palsy.

摘要:

PurposeThe purpose of this case report is to recount the rehabilitation progress of a child with a hemimeningomyelocele and to clarify terminology used to describe this condition.Summary of Key PointsA young girl with a diagnosis of a hemimeningomyelocele, involving the left hemicord only, at the level of the seventh to the ninth thoracic vertebrae, was followed from two and a half months until seven years of age. Deciphering the medical record was a challenge because clinicians involved in the case used different terminology to describe the split cord malformation. The authors had to review the literature about split cord malformations to interpret the medical record. The child also had a severe kyphoscoliosis and a ventriculoperitoneal shunt (Arnold-Chiari II deformity). The child was followed by an orthopedist and a neurosurgeon. She participated in an early intervention program that included physical therapy. Her clinical course did not follow that anticipated for a child with a meningomyelocele at the seventh through ninth thoracic vertebrae. Standing and ambulation typically are goals for children with thoracic-level lesions, primarily for exercise and for movement within the home or classroom. However, by four years of age this child was able to ambulate on even and uneven surfaces using a single-quad cane. She exhibited a normal gait pattern in the right lower extremity during ambulation. Additionally, functional movement in the left lower extremity during ambulation occurred without the use of an ankle-foot orthosis.ConclusionsThe rehabilitation progress of this child was atypical of that seen in a child with a meningomyelocele at the level of the seventh through ninth thoracic vertebrae. Because of her split cord malformation, she retained normal function in the right lower extremity although function was impaired in the left lower extremity.
