The effects of foam rolling on muscular co-activation around the knee joint

The major objectives of this thesis were to determine if foam rolling had any effect on antagonist muscle activation and whether those changes would alter muscular co-activation patterns. The results from this thesis along with current literature will help clinicians to develop adequate exercise prescription for rehabilitative and pre-activity purposes. The existing literature has shown that foam rolling or roller massagers can increase range of motion (ROM), improve performance, and alter pain perception, however little research exists regarding changes in muscle activation following foam rolling. This study developed a reliable method for measuring muscle activation around the knee joint and using that method found that foam rolling the quadriceps can impair hamstrings muscle activation likely due to greater levels of perceived pain when rolling the quadriceps.

Fall prevention among older adults: a quantitative and qualitative study

The purpose of this study was to investigate the effect of a fall prevention program on older adults as well as to explore the perceptions of older adults have on fall risk and the fall prevention program. This research was completed in Newfoundland and Labrador, Canada with participants above the age of 65. The 10-week fall prevention program focused on balance, strength, and flexibility and was followed by focus groups with the control and intervention groups. Pre and post-test measures (postural sway, TUG test, foam and dome test, ABC Scale, ESE Scale, FES Scale, SAFFE) were completed to determine if the fall prevention program decreased fall risk. The results of the quantitative portion of the study did not produce significant results however the qualitative portion was very informative. Five themes emerged from the focus group data: risk factor awareness, confidence, connectedness, quality of life, and program promotion. This research highlights the importance of fall prevention programs for older adults, not only to keep them healthy, but also for the personal and social benefits they facilitate.
