Temporal and distance parameters of 33 normal children were obtained from instrumented gait analysis prospectively over five consecutive years. The parameters were normalised to minimise the confounding effects of increasing height and leg length. Rank correlations were performed on normalised speed, normalised stride length, normalised cadence and(More)
Torsional deformities of the lower extremities are a common reason for an orthopaedic consultation and are also part of the evaluation of a patient in gait analysis. This study assessed the level of agreement between, and the repeatability of, the Footprint method and two other methods (Prone and Jig) of measuring the transmalleolar axis (TMA) clinically.(More)
This paper explores the use of Orient specks as on-body network of wireless inertial-magnetic sensors to capture the parameters of the human gait for mobile clinical gait analysis. A range of kinematic and temporal parameters were measured for normal humans using Orient specks and compared to values obtained from a commercial Vicon optical motion capture(More)
The purpose of this study was to determine the effect of simulated hamstring shortening on gait in normal subjects. Six normal subjects wore an adjustable brace to simulate three different hamstring lengths. Evaluation of the physiological cost index (PCI) and gait analysis revealed that simulated hamstring shortening produced adverse affects in the gait of(More)
OBJECTIVE To explore the use of an activity monitor (AM) to objectively characterize free-living physical activity (F-LPA) in children with mobility impairment resulting from cerebral palsy (CP). DESIGN First, a validation study compared outcomes from the AM with video evidence. Second, multiday F-LPA was characterized. Relationships between laboratory(More)
This study investigated the reliability and validity of the Visual Gait Assessment Scale when used by experienced and inexperienced observers. Four experienced and six inexperienced observers viewed videotaped footage of four children with hemiplegic cerebral palsy on two separate occasions. Validity of the Scale was obtained by comparison with(More)
The aim of this study was to assess the repeatability of an observational gait analysis score that was developed specifically for unilateral amputees. Ten videotaped sequences were analysed by six experienced observers on two separate occasions. Data were analysed using percentage agreement, the kappa statistic and the coefficient of repeatability. The(More)
OBJECTIVE To determine the relationship between the Edinburgh Visual Gait Score (EVGS) and the Gait Profile Score (GPS). METHOD Three dimensional gait data and EVGS scores from 151 diplegic children (Gross Motor Function Classification System (GMFCS) levels I-III) were used for analysis. RESULTS The EVGS correlated strongly with GPS (r=0.816). There was(More)
