"Ligament laxity" is NOT a diagnosis when working with adolescents.
This laxity - or what might be called joint hypermobility - is common and often physiologically normal in adolescents.
This isn't an opinion piece, and simply treating adolescents like little adults shows a lack of understanding around working with a younger demographic.
The research is clear, and key findings include:
A 2023 systematic review reported that generalised joint hypermobility is “common” in children and adolescents, with prevalence estimates ranging widely depending on age, s*x, ethnicity, and diagnostic criteria.
📄 Hypermobility prevalence, measurements, and outcomes in childhood, adolescence, and emerging adulthood: a systematic review, Rheumatology International, 2023
A 2024 meta-analysis combined data from over 25,000 children and found average prevalence around 33%, with prevalence higher in females than males and prevalence decreasing with maturation and adulthood.
📄Variability of joint hypermobility in children: a meta-analytic approach to set cut-off scores, Williams et al, 2024
Research also consistently shows this laxity is influenced by:
- s*x
- pubertal stage
- ethnicity
- and maturation status
All together this essentially means 1 in 3 children will present with laxity regardless of pain level or injury; that joint laxity generally decreases with age; and it is often a *normal developmental characteristic in youth* - not a pathology.
There is some evidence that hypermobility can increase injury risk in some athletic populations - especially where dynamic control is poor.
But this is a dynamic control issue, not a ligament issue.
A symptom, not a cause.
And so laxity alone should not be considered abnormal.
