Managing to learn bimanual activities – experiences from children and adolescents with cerebral palsy – a qualitative analysis

Bimanual hand use in children and adolescents with unilateral spastic cerebral palsy: an exploratory study

BACKGROUND

Individuals with unilateral spastic cerebral palsy (USCP) often show difficulties using their hands during activities of daily living.

OBJECTIVE

To investigate the factors that interfere with hand use during bimanual activities in children and adolescents with USCP.

METHODS

We conducted a cross-sectional study with 102 children and adolescents with USCP, aged 6 to 18 years. We collected information with the caregivers about the classification of the child's manual ability, according to the Manual Ability Classification System (MACS); child's age; side of the involvement; Children's Hand-Use Experience Questionnaire- CHEQ2.0. Cluster analysis identified groups of children and adolescents who performed CHEQ activities with or without assistance. Multiple linear regression analyses identified the contribution of the factors: age, sex, MACS level, side of hemiparesis, and clusters of assistance, on the outcomes of efficacy, time, and feeling bothered.

RESULTS

MACS and clusters of assistance explained the variance in efficacy (p<0.05; R2=0.31) and time (p<0.05; R2=0.37). MACS explained 22% of the variance in feeling bothered.  Children and adolescents with increased difficulty to perform activities that involve hand use (i.e., MACS III) and who receive assistance during most bimanual activities showed less efficacy of use, were slower in their performance, and presented greater feeling of being bothered.

CONCLUSION

Assistance in bimanual activities and MACS level contributed to explain the efficacy of use, time, and feeling bothered in performing bimanual activities. Intervention strategies aimed at promoting the performance of bimanual activities in the daily routine of children with USCP should consider these outcomes.

Longitudinal development of hand use in children with unilateral spastic cerebral palsy from 18 months to 18 years

AIM

To describe the development of the use of the affected hand in bimanual tasks in children with unilateral cerebral palsy (CP) from 18 months to 18 years. Specifically, whether early development can be confirmed in a larger cohort and how development progresses during adolescence.

METHOD

In total, 171 participants (95 males, 76 females; mean age 3 years 1 month [SD 3 years 8 months], range 18 months-16 years at inclusion) were classified in Manual Ability Classification System (MACS) levels I (n = 41), II (n = 91), and III (n = 39). Children were assessed repeatedly (median 7, range 2-16 times) with the Assisting Hand Assessment: in total 1197 assessments. Developmental trajectories were estimated using a nonlinear mixed effects model. To further analyse the adolescent period, a linear mixed model was applied.

RESULTS

The developmental trajectories were different between participants in MACS levels (MACS I-II, II-III) in both rate (0.019, 95% confidence interval [CI] 0.006-0.031, p = 0.034; 0.025, 95% CI 0.015-0.037, p < 0.001) and limit (19.9, 95% CI 16.6-23.3, p = 0.001; 7.2, 95% CI 3.3-11.2, p < 0.003). The individual variations were large within each level. The developmental trajectories were stable over time for all MACS levels between 7 and 18 years (p > 0.05).

INTERPRETATION

Children and adolescents with unilateral CP have considerable development at an early age and a stable ability to use their affected hand in bimanual activities from 7 to 18 years in all MACS levels.

Hand use development in children with unilateral cerebral palsy

AIM

To describe the development of hand use during bimanual activities among children with unilateral cerebral palsy (CP).

METHOD

A cohort of 166 children (79 females, 87 males; age range 18mo-13y, mean [SD] age at first assessment 37.6mo [20.5mo]) with unilateral CP, registered in the Norwegian CP Follow-up Program with two or more Assisting Hand Assessments (AHAs), were included in this longitudinal study comprising 524 AHAs. Developmental limits and rates were estimated by non-linear mixed effects models and compared between a stable limit model (SLM) and a peak and decline model. Development was described according to Manual Ability Classification System (MACS) levels and AHA performance at 18 months of age (AHA-18).

RESULTS

Children in MACS level I, or in the high AHA-18 group, reached highest limits and had the most rapid development (p<0.001). The developmental trajectories were different between MACS levels I, II, and III and between the high, moderate, and low AHA-18 groups. Seventy-five per cent of the children reached 90% of their estimated limit at 5 years 10 months or earlier. The SLM showed the best model fit (Akaike information criterion: 4008.99).

INTERPRETATION

Most children approached a steady performance limit before 6 years of age. Although children in MACS levels I and II reached 90% of the expected limit at 3 and 4 years respectively, the corresponding age was 8 years for children in MACS level III. The better model fit for the SLM indicates that children with unilateral CP maintain their attained limit of hand use to at least the age of 13 years. What this paper adds Development of hand use between 18 months and 13 years follows a stable-limit pattern. Most children reach a steady limit on the Assisting Hand Assessment before 6 years of age. Manual Ability Classification System levels I, II, and III represent distinct developmental trajectories, level III having a slower rise. Early hand use is an important indicator of future development.
