Resumen:
Introduction: In the haemophilic patient, musculoskeletal injuries mainly affect the load‐bearing joints, causing impairments in the mobility and gait. The Timed Up And Go (TUG) is a simple to perform test to assess mobility and lower extremity function. Moreover, the Harmonic Ratio (HR) is an accelerometry based measure used to quantify the walking smoothness. The objective of this study is to determine differences in the mobility and gait characteristics in a group of children with haemophilia (HG) compared with a control group (CG).
Methods: A total of 31 children with haemophilia [21 severe and 10 mild; age: 10.90 ± 1.27 years old; IMC: 18.75 ± 3.73 kg m−2; HJHS in lower limbs: 3.81 ± 2.98 points] and 27 control children [Age: 11.33 ± 1.27 years old; IMC: 18.24 ± 3.29 kg m−2] were included in the study. TUG test measures the time to rise from an arm chair, walk 3 m to a line, turn around, walk back to the chair and sit down again (2 trials). The X16‐mini accelerometer (Gulf Coast Data Concepts, LLC) was used to evaluate the HR. Children walked 30 m (3 trials) in a straight line at preferred speed with the X16‐mini placed at L3/L4 vertebrae using a belt. HR of Vertical (V), Anterior Posteri...
