Effect of Hippotherapy on Motor Proficiency and Function in Children with Cerebral Palsy Who Walk

Aims: To evaluate the effects of hippotherapy on physical capacities of children with cerebral palsy. Methods: Thirteen children (4–12 years old) with cerebral palsy classified in Gross Motor Function Classification System Level I or II were included in this prospective quasi-experimental ABA design study. Participants received 10 weeks of hippotherapy (30 min per week). Gross motor function and proficiency were measured with the Bruininks–Oseretski Motor Proficiency short form [BOT2-SF]) and the Gross Motor Function Measure-88 [GMFM-88] (Dimension D and E) twice before the program (T1 and T1′), immediately after (T2), and 10 weeks following the end of the program (T3). Results: Mean scores for dimensions D and E of the GMFM-88 Dimension scores (p = .005) and three out of the eight items of the BOT2-SF (fine motor precision (p = .013), balance (p = .025), and strength (p = .012) improved between baseline and immediately after intervention; mean scores immediately following and 10 weeks following intervention did not differ. Conclusions: Hippotherapy provided by a trained therapist who applies an intense and graded session for 10 weeks can improve body functions and performance of gross motor and fine motor activities in children with cerebral palsy.     

Active Video Gaming for Children with Cerebral Palsy: Does a Clinic-Based Virtual Reality Component Offer an Additive Benefit? A Pilot Study

Aims: To compare changes in gross motor skills and functional mobility between ambulatory children with cerebral palsy who underwent a 1-week clinic-based virtual reality intervention (VR) followed by a 6-week, therapist-monitored home active video gaming (AVG) program and children who completed only the 6-week home AVG program. Methods: Pilot non-randomized controlled trial. Five children received 1 hour of VR training for 5 days followed by a 6-week home AVG program, supervised online by a physical therapist. Six children completed only the 6-week home AVG program. The Gross Motor Function Measure Challenge Module (GMFM-CM) and Six Minute Walk Test (6MWT) evaluated change. Results: There were no significant differences between groups. The home AVG-only group demonstrated a statistically and clinically significant improvement in GMFM-CM scores following the 6-week AVG intervention (median difference 4.5 points, interquartile range [IQR] 4.75, p = 0.042). The VR + AVG group demonstrated a statistically and clinically significant decrease in 6MWT distance following the intervention (median decrease 68.2 m, IQR 39.7 m, p = 0.043). All 6MWT scores returned to baseline at 2 months post-intervention. Conclusion: Neither intervention improved outcomes in this small sample. Online mechanisms to support therapist-child communication for exercise progression were insufficient to individualize exercise challenge.     

Effect of Group Setting on Gross Motor Performance in Children 3–5 Years Old with Motor Delays

Aims: The purpose of this study was to evaluate differences in gross motor performance of children 3–5 years of age with motor delays when assessed individually compared to assessment in a group setting among peers with typical development (TD). Methods: Twenty children with motor delays and 42 children with TD were recruited from a preschool program. A within-subject repeated measures design was used; each child with delay was tested both in an individual setting and in a group setting with two to four peers with TD. Testing sessions were completed 4–8 days apart. Ten different motor skills from the Peabody Developmental Motor Scales-2 were administered. Performance of each item was videotaped and scored by a blinded researcher. Results: Overall gross motor performance was significantly different (p < .05) between the two settings, with 14 of 20 children demonstrating better performance in the group setting. In particular, children performed better on locomotion items (p < .05). Conclusions: The higher scores for locomotion in the group setting may be due to the influence of competition, motivation, or modeling. Assessing a child in a group setting is recommended as part of the evaluation process.     

Preliminary Efficacy of a Friendly Constraint-Induced Therapy (Friendly-CIT) Program on Motor and Psychosocial Outcomes in Children with Cerebral Palsy

Aims: Constraint-induced therapy (CIT) is effective, but concerns have been repeatedly raised regarding the generalizability, feasibility, and potentially intrusive nature of restraining a child's unimpaired upper limb. We examined the feasibility and efficacy of friendly-CIT, which uses home-based model, a caregiver-determined schedule, and gentle restraint, in children with cerebral palsy. Methods: In a one-group pre-post intervention trial, 15 children (median of age = 8 years, 4 months) participated in 8 weeks of friendly-CIT (36 hours). Motor and psychosocial outcomes were investigated. Results: Participants showed significant improvement on the manual dexterity subtest of the Bruininks-Oseretsky Test of Motor Proficiency (p = 0.004); the how often (p = 0.01) and how well (p = 0.02) scales of the Revised Pediatric Motor Activity Log; and the functional skills score on the Chinese version of the Pediatric Evaluation of Disability Inventory (p = 0.002). For psychosocial outcomes, children with CP consistently demonstrated high engagement and increased playfulness (p < 0.0001) during the 8-week intervention. Parents showed no change in stress status and high satisfaction with friendly-CIT. Conclusion: Friendly-CIT is feasible and promising for improving a child's motor and psychosocial outcomes without increasing parental stress.     

Development of an Age Band on the ManuVis for 3-Year-Old Children with Visual Impairments

Aim: To compare fine motor performance of 3-year-old children with visual impairment with peers having normal vision, to provide reference scores for 3-year-old children with visual impairment on the ManuVis, and to assess inter-rater reliability. Method: 26 children with visual impairment (mean age: 3 years 7 months (SD 3 months); 17 boys) and 28 children with normal vision (mean age: 3 years 7 months (SD 4 months); 14 boys) participated in the study. The ManuVis age band for 3-year-old children comprised two one-handed tasks, two two-handed tasks, and a pre-writing task. Results: Children with visual impairment needed more time on all tasks (p < .01) and performed the pre-writing task less accurately than children with normal vision (p < .001). Children aged 42–47 months performed significantly faster on two tasks and had better total scores than children aged 36–41 months (p < .05). Inter-rater reliability was excellent (Intra-class Correlation Coefficient = 0.96–0.99). Conclusions: The ManuVis age band for 3-year-old children is appropriate to assess fine motor skills, and is sensitive to differences between children with visual impairment and normal vision and between half-year age groups. Reference scores are provided for 3-year-old children with visual impairment to identify delayed fine motor development.     

A Group Motor Skills Program for Children with Coordination Difficulties: Effect on Fundamental Movement Skills and Physical Activity Participation

Aims: Children with coordination difficulties are at risk of low levels of physical activity (PA) participation. This intervention examined the effects of a multidisciplinary program that emphasized parent participation on motor skill performance and PA. Methods: Ten boys (5–7 years) completed a group program consisting of conditioning exercises and activities designed to address child-selected goals. Motor proficiency and PA participation were assessed before and after the program using the Test of Gross Motor Development (TGMD-2) and triaxial accelerometers, respectively. Rating scales captured child and parent perceptions of performance for each child's goals. Results: TGMD-2 subtest raw scores, age equivalent and percentile scores improved, along with parent ratings of their child's performance. Six children reported skill improvements. On average, moderate to vigorous PA improved by 10 min per day although these gains were not significant. Time spent in sedentary activities was unchanged. None of the children met the Canadian PA and sedentary behaviour guidelines. Conclusions: The results support effectiveness of a group program to improve gross motor performance and levels of PA in children with coordination difficulties. Gains in both of these domains also have the potential to impact quality of life and reduce health risks associated with inactivity.     

The Effect of Visual Environmental Distraction on Gait Performance in Children

Purpose: Identify the effect of visual distraction on gait parameters in children and describe the role of walking experience (WE) in the management of visual distraction. Methods: Forty-two typically developing children, mean age 43.2 months (SD = 22.9) participated and were divided into three groups according to WE: early walkers (6–11 months of WE), preschool walkers (12–37 months of WE), and experienced walkers (38–79 months of WE). Gait parameters measured under two conditions (no visual distraction and with visual distraction) included: velocity, step length, step width, and double limb support percentage (DLS%) of gait cycle. Multivariate analysis of variance assessed differences in gait between groups (effect of WE) and within groups (effect of condition). Results: Significant main effects of WE group F(8,74) = 5.300, p ≤.001 and visual distraction condition F(4,36) = 2.586, p = 0.053 were found. Visual environmental distraction significantly affected gait performance in children regardless of walking experience. Velocity decreased from 110.04 to 97.73 cm/sec (p = 0.003) while DLS% of gait cycle increased from 18.29% to 20.39% (p = 0.025). Conclusions: Results suggest physical therapists need to consider attentional requirements when assessing gait; even in children with more WE. If attention to task is a limiting factor for performance or learning of a motor task, it may need to be addressed directly as part of the treatment plan.     

Health Promotion in a Low-income Primary School: Children with and Without DCD Benefit,but Differently

ABSTRACT

Poor motor performance and reduced physical fitness are characteristic of children with Developmental Coordination Disorder (DCD). These features have also been identified more frequently among children living in low socio-economic circumstances. Aims: To evaluate the outcomes of a nine-week health promotion program (HPP) on the motor performance and fitness levels of children (6–10 years) with and without DCD attending a low-income primary school. Methods: The HPP was designed and implemented by undergraduate physiotherapy students using guidelines from the World Health Organization School Health Initiative and their physiotherapy curriculum. Children with DCD (n = 22) and a control group without DCD (n = 19) participated in the evaluation. Motor skill, functional strength, aerobic capacity, and anaerobic power were measured at baseline and after nine weeks. Results: Both groups of children improved on all measures at the conclusion of the HPP. Children with DCD showed greater improvement than the control group in motor performance and the control group showed greater improvement on one of the anaerobic fitness outcomes. Conclusions: A school-based HPP that focuses on increasing opportunities for physical activity may be effective in improving motor performance in children with DCD and can increase fitness levels in general.     

The Influence of Intense Combined Training on Upper Extremity Function in Children With Unilateral Cerebral Palsy: Does Initial Ability Matter?

Aim: To examine whether level of manual ability modifies the response to an intensive program combining modified constraint and bimanual training on arm functioning children with unilateral cerebral palsy (UCP). Methods: Thirty-four children aged 6–11 years, with Manual Ability Classification System (MACS) levels I–III (I:8, II:15, III:11), participated in a 2-week program, combining an hour of modified constraint with 5 hr of bimanual practice daily. The Assisting Hand Assessment (AHA) and the Jebsen–Taylor Test of Hand Function (JTTHF) were done pre-, post-, and 3-months post-intervention. Results: Mean AHA logits unit scores increased overtime (F_2;50 = 5, p = 0.01). There was no significant difference in AHA logits units change score between MACS levels (F_4;56 = 1.4, p = 0.22). JTTHF scores did not change for either the affected or less-affected hand, although a significant interaction of time and MACS level was found in the less-affected side (F_4;58 = 6.5, p < 0.01). Children in MACS levels I and II improved by similar degrees, in comparison to children at MACS level III who demonstrated significantly greater change over time. Conclusion: While a similar trend of improvement was found in the bimanual abilities of children at all MACS levels, only children at MACS level III had improved performance in unilateral abilities in the less-affected side following intervention.     

Retrospective Analysis of an Ongoing Group-Based Modified Constraint-Induced Movement Therapy Program for Children with Acquired Brain Injury

ABSTRACT. Aim: A pretest–posttest retrospective design was used to evaluate the impact of a group-based modified constraint-induced movement therapy (mCIMT) program on upper extremity function and occupational performance. Methods: 20 children ages 3 to 18 years with hemiplegia following an acquired brain injury participated in a 2-week group mCIMT program. Upper extremity function was measured with the Assisting Hand Assessment (AHA) and subtests from the Quality of Upper Extremity Skills Test (QUEST). Occupational performance and satisfaction were assessed using the Canadian Occupational Performance Measure (COPM). Data were analyzed using a Wilcoxon signed-ranks test. Results: Group-based analysis revealed upper extremity function and occupational performance attained statistically significant improvements from pre- to postintervention on all outcome measures (AHA: Z = ?3.63, p = <.001; QUEST Grasps: Z = ?3.10, p = .002; QUEST Dissociated Movement: Z = ?2.51, p = .012; COPM Performance: Z = ?3.64, p = <.001; COPM Satisfaction: Z = ?3.64, p = <.001). Across individuals, clinically significant improvements were found in 65% of participants’ AHA scores. 80% of COPM Performance scores and 70% of COPM Satisfaction scores demonstrated clinically significant improvements in at least one identified goal. Conclusions: This study is an initial step in evaluating and providing preliminary evidence supporting the effectiveness of a group-based mCIMT program for children with hemiplegia following an acquired brain injury.     

Younger Children with Cerebral Palsy Respond Better Than Older Ones to Therapist-Based Constraint-Induced Therapy at Home on Functional Outcomes and Motor Control

Aims: To examine the differences in efficacy of home-based constraint-induced therapy (CIT) on functional outcomes and motor control in two age groups of children with cerebral palsy (CP). Methods: Twenty-three children with spastic unilateral CP receiving 4-week home-based CIT by a therapist were divided into younger (6–8 years; n = 11) and older (9–12 years; n = 12) groups. The home-based CIT involved intensive functional training of the more affected upper-limb while restraining the less affected upper-limb. The outcome measures were Peabody Developmental Motor Scale-2nd edition (PDMS-2) that was being used in a modified way, Functional Independence Measure for Children (WeeFIM), and reach-to-grasp kinematic parameters, including reaction time (RT), normalized movement time (MT), normalized movement units (MUs), peak velocity (PV), and maximum grip aperture (MGA). The outcome measures were assessed at baseline, 4-weeks (post-treatment), 3- and 6-months (follow-up). Results: The younger group showed greater changes in visual motor integration skills and RT at all post-tests after intervention than the older group. Groups had comparable changes on any other measures. Conclusions: Younger children with CP responded better to home-based CIT on some areas of upper-limb functions and reach-to-grasp motor control strategies than older children.     

Haptic Exploratory Procedures of Children and Youth with and without Cerebral Palsy

Aims: Compare haptic exploratory procedures (EPs) and exploratory movements (EMs) of children. This study also tested the interrater reliability of a novel digital recording method. Methods: Participants were 31 children with typical development (TD) (aged 6 years 1 month to 15 years 9 months; 14 male) and 23 children with spastic unilateral cerebral palsy (CP) (aged 6 years to 15 years 5 months; 13 males; right hemiplegia, n = 12). Results: There were no statistically significant differences between groups for expected EP (p = .15), additional EPs (p = .78), or EMs (p = .69) but there was for mean duration of exploration (p < .001) and accuracy (p < .001). This suggests that although children with CP performed similar haptic EPs for each object as children with TD, they took more time and were less accurate in their identification. There was substantial agreement between the two raters' observations of expected EP, κ = .64, p < .0005. Conclusion: Children with CP performed similar haptic EPs as their TD peers. However, despite similarities, the results indicate that for children with CP manual ability was not the primary determinant of accuracy or speed of identification. This study provides evidence for a reliable method of recording haptic EPs.     

Watch Me Move: A Program For Parents of Young Children With Gross-Motor Delays

Aims: Watch Me Move (WMM) is a 6-week parent education program for caregivers of children with gross-motor delays. The aims are to improve parent-child interaction in a gross-motor context, increase parents' knowledge of behavioral cues and gross-motor development, and decrease perceived parental stress. Methods: Forty mothers of children, 6 months to 3 years of age, with a gross-motor delay participated in a randomized control trial comparing parents who received the WMM program plus standard of care physiotherapy (n = 24) with parents whose children received standard of care physiotherapy (n = 16). Results: Mothers who received the WMM program had significantly higher change scores on two subscales of the Nursing Child Assessment Teaching Scale (NCATS; i.e., cognitive growth fostering, and responsiveness to caregiver) and on the Parent Knowledge Questionnaire assessing knowledge of behavioral cues and gross-motor development. There were no significant group differences on the other four NCATS subscales (i.e., sensitivity to cues, response to child's distress, social emotional growth fostering, and clarity of cues) or the Parenting Stress Index. Conclusions: The addition of WMM to traditional physiotherapy improved aspects of mothers' ability to interact with their children and their knowledge of behavioral cues and gross-motor development.     

Test–retest Reproducibility of the Assessment of Motor and Process Skills in Children with Unilateral Cerebral Palsy

Aims: To examine test–retest reproducibility of the Assessment of Motor and Process Skills (AMPS) in children aged 8–16 years with unilateral cerebral palsy (UCP). Methods: Thirty children with mild to moderate UCP (mean age = 11y 7m, SD 2y 4m; males = 18; Manual Ability Classification System level I = 10, II = 20; Gross Motor Function Classification System level I = 9, II = 21) enrolled in a large randomized controlled trial were recruited via consecutive series sampling. Children carried out two AMPS tasks over two consecutive days according to standardized AMPS administration procedures. The standard error of measurement (SEM), smallest detectable change (SDC), 95% limits of agreement using the Bland–Altman method, and intraclass correlation coefficients (ICC; 2,1) were calculated. Results: The SDC was 0.23 logits for the AMPS motor scale and 0.30 logits for the AMPS process scale. Test–retest reliability was excellent for both the AMPS motor scale (ICC = 0.93) and the AMPS process scale (ICC = 0.86). Intra-rater reliability (n = 10) was excellent for AMPS motor scale (ICC = 0.96) and AMPS process scale (ICC = 0.98). Conclusions: The AMPS can be used by therapists with 8- to 16-year-old children with UCP as an outcome measure with changes in scores reflecting real changes in performance or capacity.     

Effect of Group-Task-Oriented Training on Gross and Fine Motor Function,and Activities of Daily Living in Children with Spastic Cerebral Palsy

Abstract

Aims: To determine the effects of group-task-oriented training (group-TOT) on gross and fine motor function, activities of daily living (ADL) and social function of children with spastic cerebral palsy (CP).

Methods: Eighteen children with spastic CP (4–7.5?years, gross motor function classification system level I–III) were randomly assigned to the Group-TOT (9 children received group-TOT for 1?hour, twice a week for 8?weeks) or the comparison group (9 children received individualized traditional physical and occupational therapy). The Gross Motor Function Measure (GMFM)-88, the Bruininks-Oseretsky Test of Motor Proficiency 2^nd edition (BOT-2), and the Pediatric Evaluation of Disability Inventory (PEDI) were administered before and after the intervention, and in the Group-TOT, 16?weeks after the intervention.

Results: Children in the Group-TOT showed significant improvements in the GMFM-88 standing and walking/running/jumping subscales, the BOT-2 manual dexterity subscale, and the PEDI social function subscale (p?<?0.05); changes were maintained 16?weeks after the intervention ended. In contrast, the comparison group improved in only the BOT-2 fine motor integration subscale (p?<?0.05).

Conclusions: The findings provide evidence of effectiveness of group-TOT in improving gross and fine motor function, and social function in children with CP.     

Factors Associated with Enhanced Gross Motor Progress in Children with Cerebral Palsy: A Register-Based Study

Aim: To examine associations between interventions and child characteristics; and enhanced gross motor progress in children with cerebral palsy (CP). Methods: Prospective cohort study based on 2048 assessments of 442 children (256 boys, 186 girls) aged 2–12 years registered in the Cerebral Palsy Follow-up Program and the Cerebral Palsy Register of Norway. Gross motor progress estimates were based on repeated measures of reference percentiles for the Gross Motor Function Measure (GMFM-66) in a linear mixed model. Mean follow-up time: 2.9 years. Results: Intensive training was the only intervention factor associated with enhanced gross motor progress (mean 3.3 percentiles, 95% CI: 1.0, 5.5 per period of ≥3 sessions per week and/or participation in an intensive program). Gross motor function was on average 24.2 percentiles (95% CI: 15.2, 33.2) lower in children with intellectual disability compared with others. Except for eating problems (–10.5 percentiles 95% CI: –18.5, –2.4) and ankle contractures by age (–1.9 percentiles 95% CI: –3.6, –0.2) no other factors examined were associated with long-term gross motor progress. Conclusions: Intensive training was associated with enhanced gross motor progress over an average of 2.9 years in children with CP. Intellectual disability was a strong negative prognostic factor. Preventing ankle contractures appears important for gross motor progress.     

Effects of Prolonged Standing on Gait in Children with Spastic Cerebral Palsy

ABSTRACT

The purpose of this study was to determine the effects of prolonged standing on gait characteristics in children with spastic cerebral palsy. Six children with spastic cerebral palsy participated in this study with an average age of 6.5 years (SD = 2.5, range = 4.0–9.8 years). A reverse baseline design (A-B-A) was used over a 9-week period. During phase A, the children received their usual physical therapy treatment. During phase B, children received the prolonged standing program three times per week, in addition to their usual physical therapy treatment. During phase A2, children received their usual physical therapy treatment. Gait analysis and clinical assessment of spasticity were performed before and after each phase. Analysis of variance (ANOVA) for repeated measurements was used to test for changes in gait measures across the four measurement sessions. Friedman's was used to test for changes in muscle tone (Modified Ashworth Scale) across the four measurement sessions. Stride length (p <.001), gait speed (p <.001), stride time (p <.001), stance phase time (p <.001), double support time (p <.003), muscle tone (p <.02), and peak dorsiflexion angle during midstance (p <.004) improved significantly following the intervention phase. The results of this study demonstrate that the gait pattern of children with cerebral palsy classified as level II or III on the Gross Motor Functional Classification System (GMFCS) improved by a prolonged standing program. However, these improvements were not maintained at 3 weeks. Further research is necessary with larger sample sizes to replicate these findings and determine specific “dosing” for standing programs to create long-lasting functional effects on gait.     

Effects of Modified Instructions on Peabody Developmental Motor Scales,Second Edition,Gross Motor Scores in Children with Typical Development

Aims: The current study assessed whether modifying instructions on the Peabody Developmental Motor Scales, Second Edition (PDMS-2) affected scores in children with typical development. Methods: The gross motor portion of the PDMS-2 was administered twice, 2–10?days apart, to 38 children. Age- and gender-matched groups received instructions in both standard and modified formats, with order depending on group assignment. Results: Gross Motor Quotient results showed an effect for instruction type (p?=?.03) and an interaction between instruction type and order (p?=?.02). Improved scores for those given modified instructions during the second session indicated the interaction favored modifications. Stationary scores showed an effect for instruction type (p?=?.01) and an interaction between instruction type and age (p?=?.02). Object Manipulation scores showed an interaction between instruction type and order only (p =.002); Locomotion scores showed no significant changes (p?=?.25). Percentile rank changes ranged from 9% to 22% across subtests. Conclusions: Findings suggested instruction modifications may change PDMS-2 gross motor scores, even in children with typical development. Findings also suggested normative scores should not be reported if modifications were used during testing. Research is needed to determine optimal cues for the best representation of true motor ability during standardized assessment.     

Motor Planning and Gait Coordination Assessments for Children with Developmental Coordination Disorder

Aims: The purposes were to examine construct validity of the Motor Planning Maze Assessment (Maze) and three items from the Functional Gait Assessment (FGA) that were modified for children (pediatric modified FGA, pmFGA), by comparing performance of children with DCD and age matched peers with typical development (TD); the construct validity of total scores of the Dynamic Gait Index (DGI) and the FGA. Methods: Twenty pairs of children with DCD and TD, age from 5 to 12 years, participated in this study. Children in both groups were tested on the Maze, pmFGA, DGI, and FGA. Paired t-tests and agreement tables were used to compare the motor performances between two groups. Results: The DCD group showed higher summary scores in the Maze (p < 0.001) and demonstrated significantly fewer steps (p ≤ 0.001) while doing the pmFGA items than the TD group. However, the FGA quality scores demonstrated minimal differences between the two groups on all three items. Children with DCD showed significantly lower DGI and FGA total scores (p < 0.001) than the TD group. Conclusion: The Maze, DGI, and FGA tests are easily applied in clinical settings and can differentiate motor planning and gait coordination between children with DCD and with TD.
