Pedobarographic and stabilometric analysis and exercises for children with recurrent ankle haemarthrosis

Background/Aims: To investigate the dynamic plantar loading characteristics, postural stability and the effectiveness of an exercise programme in children with recurrent ankle haemarthrosis. Methods: In an exploratory study, 56 children with haemophilia (Group A) and 23 typically developing children (Group B) were initially assessed. Group A received a progressive exercise programme twice a week for 6 weeks in succession. Midstance plantar loading and the dynamic limit of stability were measured using Tekscan HR MatTM pressure measurement system and Biodex Balance System respectively. Findings: Heel pressure in Group A was significantly lower than Group B (P<0.05), whereas mid-foot, forefoot, and hallux pressure were significantly higher (P<0.05). Also, Group A showed poorer postural stability (P<0.05). Furthermore, a significant correlation between postural stability and plantar loading measures was indicated in Group A. Following the completion of 6 weeks of exercises, the plantar pressure (except the medial mid-foot) and postural stability (except the mediolateral stability) for Group A were not significantly different in comparison to Group B (P>0.05). Conclusion: Dynamic plantar loading provides a potentially valuable directory for the clinicians to understand variations of postural stability in children with ankle haemarthrosis. Further, adherence to a 6-week exercise rehabilitation programme might be helpful.
