Foot And Ankle Kinematic And Lower Extremity Muscle Activity During Descent From Varying Step Heights, Emily Gerstle
Foot And Ankle Kinematic And Lower Extremity Muscle Activity During Descent From Varying Step Heights, Emily Gerstle
Theses and Dissertations
Ankle injuries are common during activities of daily living, particularly in negotiation of steps. Previous studies examining steps have generally focused on the ankle, knee, or hip and descent of multiple steps. Joint motion within the foot, utilizing a multi-segment foot model, during step descent has not been extensively studied. Although peroneal muscle activity differences have been identified between participants with healthy and unstable ankles during static activities, little is known about peroneal activity during activities of daily living. A better understanding of the foot kinematics and muscle activity in persons with uninjured ankles may help future studies elucidate the …
Role Of Sensation In Altered Phalanx Grip Force In Persons With Stroke, Leah R. Enders
Role Of Sensation In Altered Phalanx Grip Force In Persons With Stroke, Leah R. Enders
Theses and Dissertations
Many individuals experience hand impairment after stroke leading to decreased ability to perform daily living activities. Previous research studies have investigated how stroke survivors' pinch grip control differs from healthy individuals, even though many individuals can only grasp with power grip after stroke. Furthermore, many stroke survivors experience tactile sensory deficit in their paretic limb in addition to motor deficit. It is currently unknown how stroke induced tactile sensory deficit affects power grip force directional control, which is important in terms of preventing object slippage and power grip normal force generation. Additionally it is unknown if power grip could be …
Biomechanical Evaluation Of A Jackhammering Task With And Without List Assist, Blake Allen Johnson
Biomechanical Evaluation Of A Jackhammering Task With And Without List Assist, Blake Allen Johnson
Theses and Dissertations
The construction and utility industries have relatively high levels of hazardous tasks that impose high physical demands on a worker. For the past decade these industry sectors had one of highest incident rates for non-fatal injuries (BLS, 2013). The task of operating a jackhammer presents several risk factors that promote the high rates of injuries to this industry sector. Until the introduction of the lift assist, relatively few interventions were available to make the task of operating a jackhammer safer. However, no research has been conducted to support that this device is able to make jackhammering safer. The aim of …
