Insights
This study validated the box and block test for Colombian children aged 6-11, establishing normal values for upper limb function. Girls demonstrated higher average scores, and the test showed reliability and correlation with daily activities.
Area of Science:
- Pediatrics
- Neuroscience
- Occupational Therapy
Background:
- Gross motor skills evaluation is crucial for pediatric functional assessment.
- The box and block test is a recognized tool for assessing upper limb function.
Purpose of the Study:
- To validate and standardize the box and block test's normal values for Colombian children aged 6 to 11 years.
- To establish normative data for upper limb functionality in this demographic.
Main Methods:
- The box and block test was administered to 411 children from diverse socioeconomic backgrounds in Bogotá.
- Parent and teacher questionnaires assessed functional performance in daily and school activities to validate the test's construct.
Main Results:
- Data from 386 children (55.4% male) were analyzed, with 67.9% attending public schools.
- Average scores were 60.9 for the right hand and 57.8 for the left hand.
- Girls achieved significantly higher average scores than boys.
Conclusions:
- The box and block test is a reliable tool for assessing upper limb function in Colombian children.
- Normative values, standard deviations, and ranges of normality were established.
- Test results positively correlated with age, daily activities, and teachers' academic assessments, supporting its construct validity.
Objective:
Evaluating gross motor skills forms part of a child's functional examination. The box and block test is a simple, useful method for evaluating upper limb functionality. This study was aimed at validating and standardising the test's normal values in 6 to 11 year-old Colombian children.
Methods:
The test was used on 411 children from two schools in Bogotá catering for children different socioeconomic classes. A questionnaire directed towards parents and teachers was used for evaluating the children's performance on every-day life and school-related activities for validating the construct; correlation with the test was established.
Results:
Data related to 386 children (55.4% male) was analysed; 67.9% of these children were attending a public school and 90.2% had right dominance. Average test score with the right hand was 60.9 and 57.8 with the left hand.
Discussion:
Girls' average test scores were significantly higher. A table was constructed from (and showing) the average values, standard deviation and range of normality. A positive correlation was found regarding test result with age and every-day life activities and the teachers' appreciation of children's scholastic abilities. The test was reliable, having 0.84 intraclass correlation for the right hand and 0.83 for the left hand.

However, the box plot does not tell the reader about outliers - values that lie far from the center of the data. We can modify the standard box and whisker plot to identify the outliers and visualize the actual spread of the data in a sample.
