Infants partake in a developmental process between birth and 18 months which takes them from small movement while lying on their anterior side, through to walking, running, and jumping. In order to properly progress through this process, infants must learn to crawl before they learn to walk; though this process can be altered by the influence of infant locomotor devices.

The use of infant locomotor devices such as walkers, jumpers, and exersaucers are widely controversial amongst parents and pediatricians. Parents often cite benefits to the child with device exposure, whereas pediatricians often warn against the use of them. The concern of the pediatricians lay within the risk that comes along with increased mobility, as well as the upright position the device puts the child in. The child is often unable to place themselves in this position outside of the device due to not being ready in their developmental pathway. The device places the child upright with their legs hanging below with their feet not flat on the ground supporting weight. This position can place strain on the infants’ hips, lower back, and trunk.

Research shows that infants with prolonged device exposure tend to reach their locomotor milestones later than infants with average to ideal exposure. Infants with prolonged device exposure have also been found to score lower on developmental assessments. To reduce the risk of injury and developmental delay, the American Academy of Pediatrics ban the production and sale of infant walkers, and advised parents allow their children to play in more natural positions, rather than the position the locomotor devices place the child in.
In order to bridge the gap of education provided to parents and caregivers, and the knowledge of the pediatricians, further research should be done to collect up to date data of the impact of these devices and the long-term impact of these devices past the age of three. Working to expand the educational outreach to parents, particularly in the medical setting, would also be beneficial in working to reduce the exposure infants have to these devices and in turn, the number of injuries and developmental delays associated with use.

The purpose of this study was to determine the impact of yoga intensity on stress in a population of college-aged females. Stress has been shown to negatively impact health both physically and mentally, therefore it is imperative that there is a way to combat these negative health effects. Participants included females between the ages of 18-25 who had been participating in physical activity 3-5 days per week (n=11). The subjects participated in two sessions of yoga, one of lower intensity, Hatha, and one of higher intensity, Vinyasa. Stress was measured by a Stress Indicators Questionnaire, which was modified to fit the aim of the study. It was filled out by the subjects pre and post each session, resulting in four questionnaires per subject. The yoga classes were displayed through a program called YogaGlo. The data was scored and analyzed with a modified scoring guideline based off of the questionnaire guidelines and with the use of Excel. The results showed that there was a statistically significant effect of both low (p value= 0.02) and high (p value= 0.01) intensity yoga on stress. There was not a statistically significant effect between the different yoga intensities on stress (p value= 0.3). Limitations of our study include a self-selective population, no control group, and demand characteristics. The results from this study should be used for further research on yoga and various aspects of mental health, such as anxiety and depression, with a female population of all ages, longer yoga sessions, and a longitudinal study format.
