Gender Differences In Social Support During Injury Rehabilitation, Chelsey Ann Bruns 2015 University of Northern Iowa

Gender Differences In Social Support During Injury Rehabilitation, Chelsey Ann Bruns

Dissertations and Theses @ UNI

Athletic injury can be a stress-inducing event that could have negative consequences on the psychological health of the athlete (Anderson & Williams, 1988; Gould, Udry, Bridges, & Beck, 1997). Injuries not only challenge the athlete physically, but also mentally challenge their ability to cope and overcome. A growing amount of research has indicated social support as a key factor in the rehabilitation process for an injured athlete (Yang, Peek, Lowe, Heiden, & Foster, 2010). Athletic injury causes an emotional disruption, and social support could influence the athlete’s reaction to the injury and his or her ability to cope with rehabilitation …

Investigating The Effects Of Alternative Footwear On Balance, David S. May 2015 University of Mississippi. Sally McDonnell Barksdale Honors College

Investigating The Effects Of Alternative Footwear On Balance, David S. May

Honors Theses

Falls are one of the leading causes of injuries and unintentional deaths in the United States, with 27,800 fatalities attributed to falls in 2012 (National Safety Council, 2014). With two thirds of our body mass located two thirds of our body height above the ground, humans require constant work from balance control systems to prevent these falls (Winter, 1995). Because shoes can alter somatosensory input from the mechanoreceptors on the bottom of the foot and affect these balance control systems (Menant et al, 2008), they must be taken into account when looking into the causes of falls. Traditional footwear designs …
