Following the initial
paper on "abnormal sitting positions in children" data were collected
from 26 children who had previously attended Beecroft Village Podiatry Clinic. Subject were
assessed by the same podiatrist, the author, who has over 30 years experience.
Subjects had attended the clinic for various reasons and had a full
biomechanical examination performed. The subjects were not asked if they 'W'
sat until after all measurements were completed. Therefore the examiner was not
aware of any abnormal sitting position until the examination was completed. Hip rotation was measured with the child sitting, the hip
and knee were flexed. A gravity goniometer was strapped to the front of the leg
and zeroed. The hip was then maximally internally and externally rotated and the measurements noted. Subject
demographics 'W' sitters Number - 13
children , 26 hips Mean age - 6.8
years (range: 3.5 - 12.5 years) Mean internal hip rotation - 75.3˚ ± 9.5˚, external hip
rotation - 46.8˚ ± 7.2˚ Controls Number - 13 children, 26 hips Mean age - 6-9 years
(range: 2.1 - 11 years) Mean internal hip rotation - 46.8˚ ±
7.2˚. external hip rotation - 47.7˚ ± 6.7˚
Two Sample Students t-test
was used to evaluate data. Due to the
intrinsic difficulties of measuring joint range of motion, the significance
level was set at p < 0.005. Subjects who 'W' sat had a significantly higher range of internal hip rotation (p<0.000) than the age matched controls but their external hip rotation was not significantly different (p=0.82) |
