Joint mobility and motor development.
Open accessAbstract
The association of joint hypermobility and motor development was sequentially investigated in 715 infants from the ages of 8 to 14 months. Seven joints were evaluated for mobility, and each infant underwent a physical and neurological examination. Parents were given a Denver Developmental Parents' Questionnaire. All subjects with a general developmental delay, systemic illness or syndrome were excluded. The infants were classified as having normal or delayed motor development with normal or delayed joint mobility. They were re-examined six months later. Multivariate statistical techniques was used for categorical analysis, and three joints were found to be significantly associated with motor delay at the first examination--hip abduction, elbow hyperextension, and foot dorsiflexion. Of the 715 infants, 126 had joint hypermobility and of these 38 (30.2%) had motor delay. Sixty four of 589 (10.9%) with normal joints had delayed motor development. Six months later 23 out of 35 of the group with joint hypermobility and 42 out of 53 of the group with normal joints had normal motor function. Joint hypermobility is associated with an increased incidence of motor delay in infancy. Over the ensuing six months most of the subjects will catch up. These findings, indicating a favourable prognosis, have implications regarding clinical assessment and parental counselling.

A large Swedish study from 2004 reported a prevalence of 15% in girls and 6% in boys at age 12 if current age-specific recommendations of ≥6/9 on the Beighton score were applied.

The Patients and methods passage describes infants aged 8–14 months recruited in the Haifa area, not 12-year-olds in Sweden. The Abstract reports joint hypermobility among 715 infants, not prevalence of 15% in girls and 6% in boys under a ≥6/9 Beighton threshold. No page numbers are supplied for these passages.

The Patients and methods passage describes infants aged 8–14 months recruited in the Haifa area, not 12-year-old children in a 2004 Swedish study. The Results report joint hypermobility and motor delay in infants; they do not report the claimed 15% of girls under a ≥6/9 cut-off. (LLM, conf=0.88)
Checked by a reasoning model — may be wrong.
Experimental — accuracy not yet measuredHormonal changes and onset of puberty are believed to influence joint hypermobility, with an expected increase in prevalence with age among girls and a decrease among boys.

From No association between joint hypermobility, musculoskeletal pain and neurodevelopmental problems in a school-based sample of 11-year-old children (2025) · cites this paper as [5]
The Results (page unavailable) associate joint hypermobility with younger age in infants but find no significant association with sex. The Discussion (page unavailable) likewise reports no significant sex association. A search for puberty, hormonal changes, and opposite age trends in girls and boys found no passage addressing the attributed claim. (LLM, conf=0.76)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
