A cross-validation of the Violence Risk Appraisal Guide-Revised (VRAG-R) within a correctional sample.

The Violence Risk Appraisal Guide-Revised (VRAG-R) was developed to replace the original VRAG based on an updated and larger sample with an extended follow-up period. Using a sample of 120 adult male correctional offenders, the current study examined the interrater reliability and predictive and comparative validity of the VRAG-R to the VRAG, the Psychopathy Checklist-Revised, the Statistical Information on Recidivism-Revised, and the Two-Tiered Violence Risk Estimate over a follow-up period of up to 22 years postrelease. The VRAG-R achieved moderate levels of predictive validity for both general and violent recidivism that was sustained over time as evidenced by time-dependent area under the curve (AUC) analysis.

How reliable is the determination of cervical dilation? Comparison of vaginal examination with spatial position-tracking ruler.

Objective: The purpose of this study was to evaluate the accuracy of clinical measurement of cervical dilation with a position-tracking system during vaginal examination.

Study Design: This prospective study that was conducted in Poissy, France, Brooklyn, NY, and Haifa, Israel, included 333 measurements that were performed in 188 women with term singleton vertex uncomplicated pregnancies during the active stage of labor. Ninety measurements with clinical diagnosis of full dilation were excluded from analysis.

Pediatric outcomes data collection instrument scores in ambulatory children with cerebral palsy: an analysis by age groups and severity level.

Background: The Pediatric Outcomes Data Collection Instrument (PODCI) was developed in 1994 as a patient-based tool for use across a broad age range and wide array of musculoskeletal disorders, including children with cerebral palsy (CP). The purpose of this study was to establish means and SDs of the Parent PODCI measures by age groups and Gross Motor Function Classification System (GMFCS) levels for ambulatory children with CP.

Methods: This instrument was one of several studied in a prospective, multicenter project of ambulatory patients with CP between the aged 4 and 18 years and GMFCS levels I through III.

Relationships among functional outcome measures used for assessing children with ambulatory CP.

In ambulatory children with cerebral palsy (CP), practitioners often examine outcomes using measures related to functions necessary for daily life. The Gross Motor Function Measure (GMFM) Dimensions D and E, Pediatric Outcomes Data Collection Instrument (PODCI) Parent and Child versions, Gillette Functional Assessment Questionnaire (FAQ) Walking subscale, Functional Independence Measure for Children (WeeFIM), Pediatric Quality of Life Inventory (PedsQL), temporal-spatial gait parameters, and O(2) cost during ambulation were selected for study. Cross-sectional data were collected in a prospective multicenter study of 562 participants with CP (339 males, 223 females), between 4 and 18 years of age (mean age 11y 1mo).

Outcome assessments in children with cerebral palsy, part II: discriminatory ability of outcome tools.

Discriminatory ability of several pediatric outcome tools was assessed relative to Gross Motor Function Classification System (GMFCS) level in patients with cerebral palsy. Five hundred and sixty-two patients (400 with diplegia, 162 with hemiplegia; 339 males, 223 females; age range 4-18y, mean 11y 1mo [SD 3y 7mo]), classified as GMFCS Levels I to III, participated in this prospective multicenter, cross-sectional study. All tools were completed by parents and participants when appropriate.

Outcome assessments in children with cerebral palsy, part I: descriptive characteristics of GMFCS Levels I to III.

This prospective cross-sectional multicenter study assessed the relationships between Gross Motor Function Classification System (GMFCS) level and scores on outcome tools used in pediatric orthopedics. Five hundred and sixty-two participants with cerebral palsy (CP; 339 males, 223 females; age range 4-18y, mean age 11y 1mo [SD 3y 7mo]; 400 with diplegia, 162 with hemiplegia; GMFCS Levels I-III;) completed the study. The Functional Assessment Questionnaire (FAQ), Gross Motor Function Measure (GMFM) Dimensions D and E, Pediatric Quality of Life Inventory (PedsQL), the Pediatric Outcomes Data Collection Instrument (PODCI), Pediatric Functional Independence Measure (WeeFIM), temporal-spatial gait parameters, and O(2) cost were collected during one session.

Comparing functional profiles of children with hemiplegic and diplegic cerebral palsy in GMFCS Levels I and II: Are separate classifications needed?

The goal was to compare children with hemiplegia with those with diplegia within Gross Motor Functional Classification System (GMFCS) levels using multiple validated outcome tools. Specifically, we proposed that children with hemiplegia would have better gait and gross motor function within levels while upper extremity function would be poorer. Data were collected on 422 ambulatory children with cerebral palsy: 261 with diplegia and 161 with hemiplegia, across seven centers.

Sensory cueing effects on maximal speed gait initiation in persons with Parkinson's disease and healthy elders.

Researchers have suggested that sensory cues can improve gait initiation in persons with Parkinson's disease (PD); however, there is little research that documents the effects of sensory cues on gait initiation. The purpose of this study was to examine the effects of auditory and cutaneous sensory cues on maximal speed gait initiation in person's with PD and healthy elderly. Seven persons with PD of moderate severity (mean age=69 years) and seven age, gender, and height matched healthy elders participated.

Foot kinematics and kinetics during adolescent gait.

Gait analysis models typically analyze the ankle joint complex and treat the foot as a rigid segment. Such models are inadequate for clinical decision making for patients with foot impairments. While previous multisegment foot models have been presented, no comprehensive kinematic and kinetic databases for normal gait exist.
