Aim: To compare the effect of iMOVE (Intensive Mobility training with Variability and Error) therapy with dose-matched conventional therapy on gross motor development and secondary outcomes in young children with cerebral palsy., Method: This single-blind, randomized controlled trial included repeated assessments of gross motor function (using the Gross Motor Function Measure) and secondary outcomes during a 12- to 24-week intervention phase and at three follow-up points after treatment. Treatment was delivered three times per week in both groups. Forty-two children aged 12 to 36 months were stratified by age and motor function to ensure equivalence between groups at baseline., Results: Thirty-six children completed treatment and follow-up phases. Treatment fidelity was high and adherence was equivalent between groups (77.3% conventional therapy, 76.2% iMOVE). There were no group differences on the primary (gross motor function after 12 weeks p = 0.18; after 24 weeks p = 0.94) or any secondary (postural control p = 0.88, caregiver satisfaction p = 0.52, child engagement p = 0.98) measure after treatment or at the follow-up points. However, one-third of total participants exceeded predicted change after 12 weeks and 77% exceeded predicted change after 24 weeks of treatment., Interpretation: Our observations indicate a potential dose-response effect of rehabilitation therapy. We further demonstrated that individual therapeutic ingredients can be manipulated. When delivered consistently, both iMOVE and conventional therapy interventions might both be more effective than standard care., What This Paper Adds: Those receiving iMOVE therapy demonstrated more independent practice time, error, and child-initiation than those receiving the dose-matched control. iMOVE therapy was not superior to the control (conventional physical) therapy. Most participants exceeded predicted change after 24 weeks of treatment., (© 2023 Mac Keith Press.)

Background: Family empowerment in families of young children with cerebral palsy (CP) is an important consideration because the first few years of life can be overwhelming for parents. The purpose of this research was to investigate the relationship between family empowerment, fine motor (FM), gross motor (GM) and cognitive development in children with CP who were under 3 years of age., Methods: Forty-one children with a mean age of 23.8 months participated in this study. The Family Empowerment Scale (FES) was completed by the participants' parents, whereas the FM, GM and cognitive subscales of the Bayley Scales of Infant and Toddler Development Third edition (B-III) were administered by physical therapists., Results: Statistically significant positive correlations were found between the FES total and B-III raw scores for FM, GM and cognitive subscales with coefficients ranging from 0.35 to 0.41. Significant relationships were also found between the FES Community subscale and the B-III FM, GM and cognitive subscales., Conclusions: This study provides evidence of a relationship between family empowerment and FM, GM and cognitive abilities in young children with CP, with a greater severity of impairments related to lower levels of caregiver empowerment., (© 2022 John Wiley & Sons Ltd.)

Aims: Typical infant movement is characterized by a high degree of motor exploration, error, and variability. However, children with cerebral palsy (CP) often cannot create these experiences due to their neuromotor impairments. The purpose of this case study is to describe a 6-month course of physical therapy (PT) incorporating principles of infant motor learning using dynamic weight support (DWS) in a child with CP., Methods: The child was a 27-month-old girl with diplegic CP who functioned at Gross Motor Function Classification System Level IV. The child received 68 PT sessions over a six-month period. DWS was used during therapy to encourage motor practice. The therapy area was arranged to encourage active exploration, motor variability, and error experience. Gross motor function, postural control, parent perception of performance, and parent satisfaction were measured before, during, and after the course of therapy., Results: Gross motor function increased during the treatment beyond the level predicted from natural progression. Postural control fluctuated and demonstrated no appreciable improvement. Parent-perceived performance and satisfaction improved on three of four goals., Conclusions: Using DWS to incorporate principles of infant learning may have facilitated the development of gross motor skills in a child with diplegic CP.

Background: Cerebral palsy (CP) is the most common cause of motor disability in children. A concept to consider in order to meet the needs of children with CP and their families is family empowerment. Family empowerment can be defined as the process by which families acquire the skills, knowledge and resources to allow them to gain control and improve the quality of their lives. The relationship between gross motor function and family empowerment may be important because children with CP vary so widely in their ability to perform motor skills, which may affect their family's levels of empowerment. The purpose of this research was to investigate the relationship between the Family Empowerment Scale (FES) and Gross Motor Function Measure-66 (GMFM-66) in children with CP who were under 3 years of age., Methods: Forty-one children with a mean age of 23.8 months participated in this study. The FES was completed by the participants' parents or regular caregivers and includes a total score and subscales of empowerment in the family, in service situations and in community/political environments. The GMFM-66 was administered by a physical therapist and consists of a total score of gross motor function (GMFM-66) and subscores for Dimension B (sitting), Dimension C (crawling and kneeling), Dimension D (standing) and Dimension E (walking, running and jumping)., Results: Statistically significant positive correlations were found between the FES total and GMFM (total score and Dimensions B-E) with coefficients varying from 0.43-0.62. Significant relationships were also found between most subscales of the FES and the GMFM-66., Conclusions: This study provides evidence of a relationship between family empowerment and gross motor function in young children with CP and suggests that caregivers of children with higher gross motor function report higher levels of self-efficacy., (© 2020 John Wiley & Sons Ltd.)

Purpose : The purpose of this research was to investigate differences in Early Clinical Assessment of Balance (ECAB) scores within children with cerebral palsy (CP) with different Gross Motor Function Classification System (GMFCS) levels and between children with CP and typical development (TD) who are under three years of age. Methods : The ECAB was administered to fifty children (13 with TD, 16 with GMFCS level II, 11 with GMFCS level III, 10 with GMFCS level III). Results : The group of children of TD had significantly higher scores than all groups of children with CP. There were significant differences in ECAB within the groups of children with CP with different GMFCS levels. Conclusion : The results of this study support the construct validity of the ECAB as a measure of postural control in children under three years of age with CP.

Purpose: The purpose of this study was to describe changes in linear and nonlinear measures of postural control along with motor outcomes in a young child with cerebral palsy., Summary of Key Points: Posturography in sitting and standing, the Gross Motor Function Measure-66 (GMFM-66), and the Early Clinical Assessment of Balance (ECAB) were performed prior to, during, and after physical therapy. The child demonstrated independent sitting throughout the study and developed independent standing during the study. He made improvements in the GMFM-66 and ECAB throughout the study. Higher average values were found in all linear and nonlinear measures in standing when compared to sitting, which may indicate less predictable movement due to less experience with standing., Recommendations for Clinical Practice: Greater variability and lower predictability in postural control likely reflect early stages of skill acquisition. Research is needed to understand the optimal levels of movement variability and predictability.

Purpose : The Early Clinical Assessment of Balance (ECAB) is a measure of postural stability for children with cerebral palsy (CP). The purpose of this research was to investigate the relationship between the ECAB and Gross Motor Function Measure-66 (GMFM-66) and to determine the responsiveness of the ECAB in children with CP under three years of age. Methods : Twenty seven children (mean age of 25 months) participated. Data were collected before and after 3 and 6 months of physical therapy. Responsiveness was calculated using standardized response means (SRM). Results : Significant relationships were observed between the ECAB, GMFM-66 score (r = 0.87), and GMFM subscales (r = 0.63-0.86). A moderate effect size (SRM = 0.62) and a large effect size (SRM = 0.92) for the ECAB were found over the 3- and 6-month intervention periods, respectively. Conclusion : These results support the validity and responsiveness of the ECAB in young children with CP.

Introduction: Despite being a primary impairment in individuals with cerebral palsy (CP), selective motor control (SMC) is not routinely measured. Personalized treatment approaches in CP will be unattainable without the ability to precisely characterize the types and degrees of impairments in motor control. The objective of this study is to report the development and feasibility of a new methodological approach measuring muscle activation patterns during singlejoint tasks to characterize obligatory muscle co-activation patterns that may underly impaired SMC. Methods: Muscle activation patterns were recorded during sub-maximal voluntary isometric contraction (sub-MVIC) tasks at the hip, knee, and ankle with an interactive feedback game to standardize effort across participants. We calculated indices of co-activation, synergistic movement, mirror movement, and overflow (indices range 0-2, greater scores equal to greater impairment in SMC) for each isolated joint task in 15 children - 8 with typical development (TD) (mean age 4.7 ± 1.0 SD years) and 7 with CP (mean age 5.8 ± 0.7 SD years). Indices were compared with Mann-Whitney tests. The relationships between the indices and gross motor function (GMFM-66) were examined with Pearson's r. Results: Mean indices were higher in the CP vs. the TD group for each of the six tasks, with mean differences ranging from 0.05 (abduction and plantarflexion) to 0.44 (dorsiflexion). There was great inter-subject variability in the CP group such that significant group differences were detected for knee flexion mirroring (p = 0.029), dorsiflexion coactivation (p = 0.021), and dorsiflexion overflow (p = 0.014). Significant negative linear relations to gross motor function were found in all four indices for knee extension (r = -0.56 to -0.75), three of the indices for ankle dorsiflexion (r = -0.68 to -0.78) and in two of the indices for knee flexion (r = -0.66 to -0.67), and ankle plantarflexion (r = -0.53 to -0.60). Discussion: Indices of coactivation, mirror movement, synergy, and overflow during single-joint lower limb tasks may quantify the type and degree of impairment in SMC. Preliminary concurrent validity between several of the indices of SMC and gross motor function was observed. Our findings established the feasibility of a new methodological approach that quantifies muscle activation patterns using electromyography paired with biofeedback during single-joint movement.
