Positioning Device

The effects of a hand positioning device (HPD) on the quality of upper-extremity movement of five children with cerebral palsy were examined in this pilot study. Hand position was monitored during a reaching task using a single-point, 3°-of-freedom, three-dimensional tracker device. Three-dimensional path length, average velocity, movement time, response time, and the number of accelerations and decelerations (movement units) were measured. Operational definitions for each of these variables were developed for this study. Each subject performed 15 reaching trials at a pretest and posttest. A 6-week intervention period followed the pretest where each subject wore the HPD for 1 hour daily for functional activities. Group results showed no significant differences for any of the variables being measured. However, individual data analysis revealed that the HPD has the potential for modifying the quality of reaching motions in some children with cerebral palsy. The nature of the changes observed among these five subjects is discussed, as well as suggestions for future research studies. Finally, this initial study shows that the tracker is a sensitive method for recording qualitative changes in the upper-extremity motion of children with cerebral palsy in occupational therapy research.

Direct Kinematics

Multibody optimisation approaches have not seen much use in routine clinical applications despite evidence of improvements in modelling through a reduction in soft tissue artifacts compared to the standard gait analysis technique of direct kinematics. To inform clinical use, this study investigated the consistency with which both approaches predicted post-surgical outcomes, using changes in Gait Profile Score (GPS) when compared to a clinical assessment of outcome that did not include the 3D gait data. Retrospective three-dimensional motion capture data were utilised from 34 typically developing children and 26 children with cerebral palsy who underwent femoral derotation osteotomies as part of Single Event Multi-Level Surgeries. Results indicated that while, as expected, the GPS estimated from the two methods were numerically different, they were strongly correlated (Spearman’s ρ = 0.93), and no significant differences were observed between their estimations of change in GPS after surgery. The two scores equivalently classified a worsening or improvement in the gait quality in 93% of the cases. When compared with the clinical classification of responders versus non-responders to the intervention, an equivalent performance was found for the two approaches, with 27/41 and 28/41 cases in agreement with the clinical judgement for multibody optimisation and direct kinematics, respectively. With this equivalent performance to the direct kinematics approach and the benefit of being less sensitive to skin artefact and allowing additional analysis such as estimation of musculotendon lengths and joint contact forces, multibody optimisation has the potential to improve the clinical decision-making process in children with cerebral palsy.

AIMS: To analyze the linear parameters of the gait of children with spastic hemiparetic cerebral palsy, users of articulated ankle and foot orthoses.METHODS: A three-dimensional analysis of the gait of eight children with spastic hemiparetic cerebral palsy, aged 5 to 10 years, classified in levels I and II of the Gross Motor Function Classification System, was made with and without the use of ankle and foot orthoses. A kinematic system with seven integrated cameras captured the three-dimensional trajectory of markers in the participants' body during gait, with data being collected at a sampling rate of 100 Hz. For the comparisons, the paired t-test and the t-test for a sample were used.RESULTS: Considering the gait’s spatiotemporal variables of these children with cerebral palsy compared to normal values, only velocity (with the orthosis and without the orthoses) presented a statistically significant difference. The mean normal gait velocity is 1.25 m/s, while in the non-orthoses participants the mean velocity was 0.98±0.10 m/s (p=0.0001) and with the use of orthoses the mean velocity was 0.96±0.21 m/s (p=0.0001). In the comparison between children using or not the ankle and foot orthoses, velocity, cadence and pitch length were respectively 0.98±0.10 m/s, 131±16.15 steps/min and 0.44±0.08 m in the children without the orthoses; and 0.96±0.21 m/s, 128.37±22.9 steps/min and 0.48±0.05 m in the children with the orthoses. The differences were not statistically significant.CONCLUSIONS: Comparison between the same group with and without the use of ankle and foot orthoses suggests that their use in children with cerebral palsy may promote an increase in step length and a decrease in velocity and cadence in relation to condition without orthosis, favouring a better distribution of weight in the paretic member and providing a better symmetry in gait. However, the differences were not statistically significant. Thus, it is expected that the results obtained in this study can serve as a pilot for future research, with larger samples.
