Purpose: To evaluate the effects of a short-term intensive virtual reality intervention in adolescents with cerebral palsy (CP). Methods: Single-subject design, type A–B-follow-up, with four participants (P) with CP, 15–18 years, GMFCS level II. A two-week intervention phase was performed with twelve Nintendo® Wii games in six sessions (90 min) per week. Outcome variables were semi-static balance (Pressure Center Oscillation—PCO), gait speed (Ten Meter Walk Test at usual speed—TMWT-U; and fast speed—TMWT-F), mobility (Timed Up and Go test—TUG), endurance (sit-to-stand test 5 times—STS-5), and gross motor activity (Gross Motor Function Measure—GMFM). Results: Statistical improvements were observed in GMFM-D (P2–P3), TMWT-F (P2–P3–P4) and TMWT-U (P2), STS-5 (P3–P4), TUG (P3), and PCO (P2–P3), assessed by level, trend, latency, and visual inspection to analyze change. Conclusions: This study shows that a short-term intensive intervention using Nintendo® Wii-based games in adolescents, GMFCS level II, can be an effective therapy, leading to some recovery of functioning in these young people.

Background and Purpose Virtual reality (VR) creates an exercise environment in which the intensity of practice and positive feedback can be systematically manipulated in various contexts. The purpose of this study was to investigate the training effects of a VR intervention on reaching behaviors in children with cerebral palsy (CP). Participants Four children with spastic CP were recruited. Method A single-subject design (A-B with follow-up) was used. All children were evaluated with 3 baseline, 4 intervention, and 2 follow-up measures. A 4-week individualized VR training program (2 hours per week) with 2 VR systems was applied to all children. The outcome measures included 4 kinematic parameters (movement time, path length, peak velocity, and number of movement units) for mail-delivery activities in 3 directions (neutral, outward, and inward) and the Fine Motor Domain of the Peabody Developmental Motor Scales–Second Edition (PDMS-2). Visual inspection and the 2-standard-deviation–band method were used to compare the outcome measures. Results Three children who had normal cognition showed improvements in some aspects of reaching kinematics, and 2 children’s change scores on the PDMS-2 reached the minimal detectable change during the intervention. The improvements in kinematics were partially maintained during follow-up. Discussion and Conclusion A 4-week individualized VR training program appeared to improve the quality of reaching in children with CP, especially in children with normal cognition and good cooperation. The training effects were retained in some children after the intervention.

Abstract Background and Purpose. People with spastic cerebral palsy often receive passive stretching that is intended to maintain or increase joint passive range of motion (PROM) even though the effectiveness of these exercises has not been definitively demonstrated. The purpose of this study was to determine the effect of PROM exercises on 6 adults with spastic quadriplegia and contractures. Participants. Four men and 2 women (X̄=31 years of age, range=20–44 years) who lived in an institution for people with mental retardation participated in the study. Methods. The authors used 2 multiple baseline designs. Three participants (group 1) received lower-extremity PROM exercises during phase A; PROM exercises were discontinued during phase B. Three participants (group 2) did not receive PROM exercises during phase A; PROM exercises were initiated during phase B. Data were analyzed using visual analysis and the C statistic. Results. Results varied with the method of analysis; however, phase A and phase B measurements, overall, did not differ for either group. Discussion and Conclusion. This study demonstrated use of a single-subject design to measure the effect of PROM exercises on adults with cerebral palsy. The authors concluded that the PROM exercise protocol did not have an effect on the lower-extremity goniometric measurements of the participants.

Abstract Background and Purpose. Development of gross motor function in children with cerebral palsy (CP) has not been documented. The purposes of this study were to examine a model of gross motor function in children with CP and to apply the model to construct gross motor function curves for each of the 5 levels of the Gross Motor Function Classification System (GMFCS). Subjects. A stratified sample of 586 children with CP, 1 to 12 years of age, who reside in Ontario, Canada, and are known to rehabilitation centers participated. Methods. Subjects were classified using the GMFCS, and gross motor function was measured with the Gross Motor Function Measure (GMFM). Four models were examined to construct curves that described the nonlinear relationship between age and gross motor function. Results. The model in which both the limit parameter (maximum GMFM score) and the rate parameter (rate at which the maximum GMFM score is approached) vary for each GMFCS level explained 83% of the variation in GMFM scores. The predicted maximum GMFM scores differed among the 5 curves (level I=96.8, level II=89.3, level III=61.3, level IV=36.1, and level V=12.9). The rate at which children at level II approached their maximum GMFM score was slower than the rates for levels I and III. The correlation between GMFCS levels and GMFM scores was −.91. Logistic regression, used to estimate the probability that children with CP are able to achieve gross motor milestones based on their GMFM total scores, suggests that distinctions between GMFCS levels are clinically meaningful. Conclusion and Discussion. Classification of children with CP based on functional abilities and limitations is predictive of gross motor function, whereas age alone is a poor predictor. Evaluation of gross motor function of children with CP by comparison with children of the same age and GMFCS level has implications for decision making and interpretation of intervention outcomes.

The Stability

The primary purpose of this exploratory study was to examine the stability and lability of negative mood from a health perspective. Negative mood factor structure was examined in order to evaluate intra-individual change. Few studies have addressed factorial invariance across individuals and across time. The sample was comprised of four women in their 60s and four women in their 80s. Short-term intra-individual change and inter-individual differences in negative mood were assessed with a replicated single-subject design. Participants completed items from the 8SQ questionnaire for 100 consecutive days. P-technique factor analysis was used to examine the structure of negative mood factors, which were than graphed to determine level change over time. The number of factors were consistent, however, the items comprising the factors were not consistent across all participants. Patterns of intra-individual change in the negative mood factor of “ fatigue” was found to be highly individualised.
