Biomechanical Assessment Of The Lower Extremity Following An Unexpected Ankle Perturbation, Emilia Gladys Schempp
Biomechanical Assessment Of The Lower Extremity Following An Unexpected Ankle Perturbation, Emilia Gladys Schempp
Theses and Dissertations
A deeper understanding of the response to an unexpected ankle perturbation could help provide insight into ankle sprain injury avoidance strategies. This study compared lower extremity electromyographic and kinematic measures between unexpected ankle perturbation and normal walking conditions, including muscle amplitudes and reaction times, dominant limb joint angles and velocities. Trial conditions included a walking control condition, unexpected 30° inversion, and unexpected 18° combined inversion and plantarflexion. With randomized trials, 20 healthy volunteers walked along the custom-built walkway that unexpectedly released into the described ankle perturbations. Significant differences were found for peak and average EMG of the peroneus longus and …
Alterations In Foot Positioning During Ankle Taping And Its Effects On Range Of Motion And Jump Performance In Dancers, Eilish Anderson
Alterations In Foot Positioning During Ankle Taping And Its Effects On Range Of Motion And Jump Performance In Dancers, Eilish Anderson
Theses and Dissertations
Context: A closed basket-weave ankle tape application is commonly used by healthcare professionals in order to give support to the athlete’s ankle during activity. This closed basket-weave ankle tape is used to prevent the ankle joint from going into excessive plantarflexion and inversion. Previous research has demonstrated traditional ankle taping techniques, with the ankle in a dorsiflexed position, reduces range of motion at the ankle. Due to the extreme demands placed on the ankle during dancing, which often requires the dancer to place the ankle in a maximally plantarflexed position, it is unclear how taping in this position affects range …
The Effects Of A Foot-Toe Orthosis On Dynamic Balance And Hallux Valgus Angle, Adam Richard Kelly
The Effects Of A Foot-Toe Orthosis On Dynamic Balance And Hallux Valgus Angle, Adam Richard Kelly
Theses and Dissertations
Context: Decreased balance has been identified as a risk factor for lower extremity injury in several populations. Previous literature has investigated the effects of using orthotics, textured insoles and textured surfaces on balance. However, no research exists on the effects of a foot-toe orthosis on dynamic balance. Objective: To determine the effects of a foot-toe orthosis on dynamic balance and hallux valgus angle. Design: A randomized controlled trial. Setting: Athletic Training research laboratory. Participants: Sixty-three healthy and recreationally active collegiate students. (age: 21.59±1.49yrs, height 172.48±8.99cm, mass 73.86kg±15.64kg) Interventions: Participants were randomly allocated to one of three groups that received either …
A Comparison Of Functional Manual Reaction To Passive Joint Mobilization On Dorsiflexion And Star Excursion Reach Distance, Timothy Frederic Boerger
A Comparison Of Functional Manual Reaction To Passive Joint Mobilization On Dorsiflexion And Star Excursion Reach Distance, Timothy Frederic Boerger
Theses and Dissertations
Context: Joint mobilizations (JM) and functional manual reaction (FMR) are techniques commonly utilized in rehabilitation to promote restoration of ankle dorsiflexion (DF). Additionally, it is possible that JM have an effect upon postural control. Purpose: The purpose of this study was to investigate the comparative immediate effects of JM and FMR on DF and Star Excursion Balance (SEBT) reach distance in healthy subjects. Design: Randomized controlled trial. Setting: A university laboratory. Patients or other participants: We included 43 college aged subjects for our investigation (20M, 23F). Main outcome variables: Our variables were straight knee DF, bent knee DF, anterior SEBT, …
