Insights
Generalized joint hypermobility (GJH) affects nearly 22% of children in Irish physiotherapy services. GJH did not impact physical activity or motor coordination in these children.
Area of Science:
- Paediatric physiotherapy
- Clinical assessment of hypermobility
- Developmental coordination disorder
Background:
- Generalized joint hypermobility (GJH) and generalized hypermobility spectrum disorder (gHSD) require updated classification systems for accurate diagnosis.
- Understanding the prevalence and impact of GJH and gHSD in pediatric populations is crucial for targeted interventions.
Purpose of the Study:
- To determine the prevalence of GJH and gHSD in a community pediatric physiotherapy service in Ireland using a new classification system.
- To investigate the relationship between GJH, gHSD, physical activity levels, and probable developmental coordination disorder (pDCD).
Main Methods:
- A case-controlled cross-sectional study involving children aged 6-12 years recruited from physiotherapy and school settings.
- GJH identified using a Beighton score (≥6/9); gHSD assessed using the latest framework.
- Physical activity measured via self-report (Physical Activity Questionnaire-Older Children); pDCD screened using a parent-reported questionnaire.
Main Results:
- GJH prevalence was 21.9% among children in physiotherapy. gHSD prevalence was 3.1% in the physiotherapy group.
- No significant difference in physical activity levels was found between children with and without GJH.
- Probable developmental coordination disorder (pDCD) was highly prevalent (71.9%) in the physiotherapy group, with no significant association with GJH.
Conclusions:
- This study provides the first prevalence data for GJH and gHSD in the Irish pediatric physiotherapy population.
- GJH in children attending physiotherapy did not appear to influence their self-reported physical activity or motor coordination.
Objective:
The primary aim of the study was to explore the prevalence of generalized joint hypermobility (GJH) and generalized hypermobility spectrum disorder (gHSD) using the new classification system in a community paediatric physiotherapy service in Ireland. The second aim was to explore the relationship between GJH, gHSD and physical activity level, while considering the association of probable developmental coordination disorder (pDCD).
Methods:
A case-controlled cross-sectional study of children aged 6-12 years, recruited from the community paediatric physiotherapy department (n = 32) and a local school (n = 41), was carried out. A Beighton score of ≥6/9 distinguished GJH. The new framework for hypermobility spectrum disorder (HSD) was used. Self-reported physical activity level was measured using the Physical Activity Questionnaire-Older Children. A parent-reported validated questionnaire screened for pDCD.
Results:
The prevalence of GJH was 21.9% of children attending physiotherapy. One child in the physiotherapy group was identified as having gHSD, with a prevalence of 3.1%. There was no significant difference in physical activity level between children with and without GJH attending physiotherapy (independent samples t-test, p = 0.28). Probable developmental coordination disorder (pDCD) was observed in 71.9% of children attending physiotherapy. There was no significant difference in the number of children with pDCD in those with and without GJH (Fisher's exact test, p = 0.370).
Conclusions:
This study was the first to explore the prevalence of GJH and gHSD in the paediatric physiotherapy population in Ireland. The presence of GJH did not affect self-reported physical activity level or motor coordination in children attending physiotherapy.

When a particle moves relative to an inertial frame, the equations of motion can be expressed using rectangular components. If the motion is confined to the x-y plane, the equations having the x and y coordinates only can be used to simplify the mathematical representation.
