COMPARISON OF HEART RATE AND OXYGEN CONSUMPTION BETWEEN TREADMILL WALKING AND FREE AMBULATION IN CHILDREN WITH CEREBRAL PALSY

The purpose of this study was to examine the cardiovascular responses to water treadmill walking at 2.0 mph (3.2 km/hr), 2.5 mph (4.0 km/hr), and 3.0 mph (4.8 km/hr) in older adults. Responses to water treadmill walking in 92 °F (33 °C) water were compared with responses to land treadmill walking at 70 °F (21 °C) ambient temperature. After an accommodation period, participants performed 5-min bouts of walking at each speed on 2 occasions. Oxygen consumption (VO2), heart rate (HR), systolic blood pressure (SBP), and rating of perceived exertion (RPE) were significantly higher during therapeutic water treadmill walking than during land treadmill walking. Furthermore, VO2, HR, and RPE measures significantly increased with each speed increase during both land and water treadmill walking. SBP significantly increased with each speed during water treadmill walking but not land treadmill walking. Thus, it is imperative to monitor HR and blood pressure for safety during this mode of activity for older adults.

Abstract Cerebral palsy (CP) is the most prevalent severe motor disability among children. The aim of this work was to assess autonomic dysfunction in children with cerebral palsy clinically and electrophysiologically .The study was carried out on forty children with cerebral palsy their age ranged from 4-12 years and twenty healthy children with matched age and sex as control group. CP children were subjected to questionnaire for autonomic dysfunction symptoms. Both CP children and Control group were assessed for Sympathetic Skin Response and Heart rate variability. Most of children had quadriplegic spastic cerebral palsy (82.5%). Based on Gross motor function classification system (GMFCS) classification the majority of children were in levels 4 and 5. The prevalence of autonomic dysfunction symptoms was 80% for thermoregulatory abnormalities (cold extremities), chronic constipation 65%, sleep disturbance 52.5%, loss of appetite 47.5%, sweating abnormalities 40% , recurrent nausea and/or vomiting 25%, increased sensitivity to light or dark 22.5% and bloating 15%. The percentage of unelicited Sympathetic skin response in CP children was 47.5% and 60% in upper limbs and lower limbs respectively, all of them were in level 4 and 5 of GMFCS. 20% of CP children had postural hypotension. Mean Heart rate of CP children was significantly increased more than healthy children upon head tilt test. Sympathetic Skin Response and Heart rate variability were proven to be simple and non invasive procedures in investigating autonomic dysfunction in CP children.

Recumbent stationary cycling is a potential exercise modality for individuals with cerebral palsy (CP) that lack the postural control needed for upright exercises. Functional electrical stimulation (FES) of lower extremity muscles can help such individuals reach the cycling intensities that are required for aerobic benefits. The aim of this study was to examine the effect of cycling with and without FES assistance to that of a no-intervention control group on the cardiorespiratory fitness of children with CP. Thirty-nine participants were randomized to a FES group that underwent an 8-week FES-assisted cycling program, the volitional group (VOL), who cycled without FES, or a no-intervention control group (CON) (15 FES, 11 VOL, 13 CON). Cadence, peak VO2, and net rise in heart rate were assessed at baseline, end of training, and washout (8-weeks after cessation of training). Latent growth curve modeling was used for analysis. The FES group showed significantly higher cycling cadences than the VOL and CON groups at POST and WO. There were no differences in improvements in the peak VO2 and peak net HR between groups. FES-assisted cycling may help children with CP attain higher cycling cadences and to retain these gains after training cessation. Higher training intensities may be necessary to obtain improvements in peak VO2 and heart rate.
