Measuring global activity performance in children with cerebral palsy in West Africa: validation of an adapted version of the ACTIVLIM-CP questionnaire

PURPOSE

To calibrate a West-African version of the ACTIVLIM-CP questionnaire (ACTIVLIM-CP-WA) for children with cerebral palsy (CP).

MATERIALS AND METHODS

We recruited 287 children with CP of various age range: 2-6 years (n = 117, preschoolers), 6-12 years (n = 96, children) and 12-19 years (n = 74, adolescents). Caregivers of children of each age range completed the experimental version of the ACTIVLIM-CP-WA including 76 (preschoolers), 78 (children) and 76 (adolescents) global daily life activities. Responses were analyzed using the Rasch RUMM2030 software.

RESULTS

The final West-African version of ACTIVLIM-CP including 31 items (both common and age-specific items) defined a unidimensional, linear scale with well-discriminated response categories. It presented a high internal consistency (R = 0.94). Moreover, all items were locally independent and the item difficulty hierarchy was invariant regarding caregivers' education, children's age and gender, MACS and GMFCS levels. The ACTIVLIM-CP-WA measures were significantly correlated (p < 0.05) with Gross Motor Function Classification System (ρ = -0.77), Manual Ability Classification System (ρ = -0.75), Box and Block test (dominant hand r = 0.51; non-dominant hand r = 0.49), One-minute walking test (r = 0.28), and Timed up and Go test (r = -0.40).

CONCLUSIONS

The ACTIVLIM-CP-WA questionnaire provides a valid and reliable tool that has the potential to follow children's evolution and quantify changes consecutive to neurorehabilitation in Sub-Saharan Africa.IMPLICATIONS FOR REHABILITATIONThe West-African version of the ACTIVLIM-CP questionnaire (ACTIVLIM-CP-WA) measures global activities requiring a combination of lower and upper extremities in children with cerebral palsy.As a Rasch-built scale, measures are unidimensional and linear to document changes in children with cerebral palsy from 2 to 19 years in Sub-Saharan Africa.Rehabilitation professionals are encouraged to use the ACTIVLIM-CP-WA questionnaire as a psychometrically robust assessment tool measuring the global performance in daily life activities in children with cerebral palsy in Sub-Saharan Africa.

Effectiveness of a self-rehabilitation program to improve upper-extremity function after stroke in developing countries: A randomized controlled trial

BACKGROUND

About two-thirds of stroke patients present long-term upper-limb impairment and limitations of activity, which constitutes a challenge in rehabilitation. This situation is particularly true in developing countries, where there is a need for inexpensive rehabilitation solutions.

OBJECTIVE

This study assessed the effectiveness of a self-rehabilitation program including uni- or bi-manual functional exercises for improving upper-limb function after stroke with respect to the context in Benin, West Africa.

METHODS

In this single-blind randomized controlled trial, chronic stroke individuals (>6 months post-stroke) performed a supervised home-based self-rehabilitation program for 8 weeks (intervention group); the control group did not receive any treatment. Participants were assessed before treatment (T0), at the end of treatment (T1) and 8 weeks after the end of treatment (T2). The primary outcome was the manual ability of the upper limb, assessed with ABILHAND-Stroke Benin. Secondary outcomes were grip force, motor impairment (Fugl-Meyer Assessment - Upper Extremity), gross manual ability (Box and Block test, Wolf Motor Function test) and quality of life (WHOQOL-26).

RESULTS

We included 28 individuals in the intervention group and 31 in the control group. Adherence to the program was 83%. After 8 weeks of self-rehabilitation, individuals in the intervention group showed significantly improved manual ability and grip force as compared with the control group (P<0.001), with effect size 0.75 and 0.24, respectively. In the intervention group, the difference in average scores was 10% between T0 and T1 and between T0 and T2. Subscores of physical and psychological quality of life were also significantly improved in the intervention group. The other variables remained unchanged.

CONCLUSIONS

A self-rehabilitation program was effective in improving manual ability, grip force and quality of life in individuals with stroke in Benin. More studies are needed to confirm these results in different contexts.
