The aim of this study was to assess the effect of partial body weight support on the oxygen cost of treadmill walking in children and adolescents with spastic cerebral palsy (CP). Five children and adolescents (2 girls and 3 boys) with spastic CP (12.4 ± 3.6 years) volunteered for the study. Participants performed three 4-min tread mill walks on three separate days at their comfortable treadmill walking speeds. At each visit a different partial body weight harness setting was used. Significant (p < .05) differences in oxygen cost were found when the harness was worn but not connected to the support frame. Partial body weight support reduces the oxygen cost of walking in children and adolescents with spastic CP.

Aim. To evaluate the effects of aquatic (AQ) compared to a land-based (LB) intervention programs on metabolic cost of walking (MCW), gross motor function and locomotor performance in children with cerebral palsy (CP). Methods. Eleven children with spastic diplegic CP completed this study, six in the AQ (5.2 ± 1.45 yrs) and five in the LB group (4.1 ± 1.33 yrs). MCW derived from Oxygen uptake (VO2) measured with a Cosmed K4 device and walking speed at steady state. Additional measures included the 10-m test, Gross Motor Function Measure (GMFM), and Pediatric Evaluation Developmental Inventory (PEDI). Non-parametric statistics were used to analyze change in each group. Results. The AQ group significantly decreased MCW (Z=−2.2; P<.05) and increased steady state walking speed (Z=−2.2; P<.05). Both groups significantly increased 10-m walking speed (Z=−2.2; P<.03, and Z=−2.02; P<.05, resp.). The LB group exhibited moderate to large effect sizes in 10-m self-selected and fast walking speeds (Cohen's d=1.07 and 0.73, resp.). Conclusion. Our findings suggest that Both AQ and LB programs were effective in improving 10-m speed, while the AQ training also improved the MCW of walking at steady state in children with spastic diplegic CP.

Oxygen consumption (VO2) is the criterion standard for determining energy expenditure during activity. Newer technologies have resulted in the development of portable metabolic gas analyzers capable of measuring VO2 during a wide range of physical activities in the field. Unfortunately, use of these devices is still limited due to the cost, availability and skill level required to utilize this newer technology. However, there is an instrument which may be utilized. Accelerometers are a type of physical activity monitor that provide estimates of energy expenditure and may potentially be of more practical use in the clinical setting. Purpose: This study was designed to compare estimates of energy expenditure using two different accelerometers to VO2 during self-paced walking speeds in children with spastic diplegia cerebral palsy (CP) and in healthy children (HLT). Methods: Ten HLT children and five children with spastic diplegia CP participated in this pilot study (age range: 7.5-17.5 years). Subjects ambulated at self-paced speeds on a level surface wearing a Caltrac accelerometer and a BioTrainer-Pro accelerometer, while VO2 was measured simultaneously with an AeroSport KB1-C portable metabolic gas analyzer. Results: Both accelerometers overestimated caloric expenditure in HLT children. In the children with spastic diplegia CP, we found no significant differences in the mean caloric expenditure estimated by the accelerometers and VO2 (p= 0.62). Conclusions: Preliminary findings suggest accelerometers may have potential as a means of estimating energy expenditure during ambulation in children with spastic diplegia CP, which could be useful to clinicians evaluating therapeutic interventions. Further research is indicated.

Neuromuscular disorders in Cerebral Palsy (CP) patients lead to foot deformities and affect foot biomechanics leading to compromised gait. The objective of the present work is to develop a wearable instrumentation to measure foot kinematics such as foot-to-ground angle in three-dimensional planes and to measure the foot clearance i.e., toe and heel clearances. A template-based outsole was developed that incorporated an optical distance sensor located anatomically on the outsole and the magnetometer to measure the foot kinematics. The developed system was validated against the reference marker-based motion capture system. The data from eight able-bodied participants were acquired simultaneously from both the systems at three different walking speeds. A CoP based feedback was presented to the participants to shift the sagittal CoP anteriorly, posteriorly and normal to simulate the walking pattern of CP patients with three different foot landing strategies. Pearson’s correlation coefficient of more than or equal to 0.62, root mean square error of less than or equal to 7.81 degrees and limit of agreement of more than or equal to 95% is found. The measurement accuracy reported with outsole while participants simulated CP gait shows the potential of present work in real-time foot kinematics detection in CP patients.
