Anatomy Of The Ankle And Ankle Injuries In Athletes, Isabelle G. West

Honors Capstones

The purpose of this project was to learn about the anatomy of the ankle joint, explore common ankle injuries in athletes, and research how they are treated overall and in a physical therapy setting. To do so, a dissection of the ankle joint was completed with Mrs. Kara Coffman-Rea in the cadaver lab as well as an exploration of plastinated models. Additionally, a literature review of current research on the ankle was completed. Though many structures of the ankle joint were identified through dissection, the focus of the literature review is on the structures of the lateral ankle and the …

Co-Contraction Of Ankle Muscle Activity During Quiet Standing In Individuals With Incomplete Spinal Cord Injury Is Associated With Postural Instability, Kai Lon Fok, Jae W Lee, Janelle Unger, Katherine Chan, Kristin E Musselman, Kei Masani

Physical Therapy Publications

Previous findings indicate that co-contractions of plantarflexors and dorsiflexors during quiet standing increase the ankle mechanical joint stiffness, resulting in increased postural sway. Balance impairments in individuals with incomplete spinal cord injury (iSCI) may be due to co-contractions like in other individuals with reduced balance ability. Here we investigated the effect of co-contraction between plantar- and dorsiflexors on postural balance in individuals with iSCI (iSCI-group) and able-bodied individuals (AB-group). Thirteen able-bodied individuals and 13 individuals with iSCI were asked to perform quiet standing with their eyes open (EO) and eyes closed (EC). Kinetics and electromyograms from the tibialis anterior (TA), …

Experimental & Simulation Approaches To Study Neuromuscular Control In People With Chronic Ankle Instability, Hoon Kim

Dissertations (1934 -)

Ankle sprains are among the most common musculoskeletal injuries, and up to 70% of people who sprain their ankles develop chronic ankle instability (CAI). Moreover, people who develop CAI have a significantly higher risk of developing ankle osteoarthritis. Recent research has identified neuromuscular deficits that may be responsible for the high recurrence rates of ankle sprains and for the progression towards ankle osteoarthritis in people with CAI. Unfortunately, current rehabilitation strategies are not completely successful because the mechanisms responsible for these deficits are not fully elucidated. Therefore, the purpose of this dissertation was to investigate individual muscle forces and force …

Comparing The Effects Of Tissue Flossing And Instrument Assisted Soft Tissue Mobilization On Ankle Dorsiflexion, Sean Carlson, Garrett Rife, Zachary Williams

The Research and Scholarship Symposium (2013-2019)

Purpose: The purpose of this study is to evaluate the claimed effects of a new technique called Tissue Flossing and compare those effects with Instrument Assisted Soft Tissue Mobilization, or IASTM. Background: Tissue flossing is a relatively new technique that utilizes a large rubber band that is wrapped around the involved joint. Once applied, range of motion exercises are completed, and the band is removed. The goal is to increase joint range of motion. IASTM involves using a specialized tool to scrape an effected muscle or tendon of the body. The goal is to reduce any adhesions or scar tissue …

Response Shift After A 4-Week Multimodal Intervention For Chronic Ankle Instability, Cameron J. Powden, Matthew C. Hoch, Beth E. Jamali, Johanna M. Hoch

Rehabilitation Sciences Faculty Publications

Context The accurate evaluation of self-reported changes in function throughout the rehabilitation process is important for determining patient progression. Currently, how a response shift (RS) may affect the accuracy of self-reported functional assessment in a population with chronic ankle instability (CAI) is unknown.

Objective To examine the RS in individuals with CAI after a 4-week multimodal rehabilitation program.

Design Controlled laboratory study.

Setting Laboratory.

Patients or Other Participants Twenty adults (5 men, 15 women; age = 24.35 ± 6.95 years, height = 169.29 ± 10.10 cm, mass = 70.58 ± 12.90 kg) with self-reported CAI participated. Inclusion criteria were at …

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 …

Altered Tendon Characteristics And Mechanical Properties Associated With Insertional Achilles Tendinopathy, Ruth L. Chimenti, Adolph S. Flemister, Joshua Tome, James M. Mcmahon, Marie A. Flannery, Ying Xue, Jeff R. Houck

Faculty Publications - College of Physical Therapy

Study Design: Case-control laboratory study.

Objectives: To compare tendon characteristics (shape, composition) and mechanical properties (strain, stiffness) on the involved side of participants with insertional Achilles tendinopathy (IAT) to the uninvolved side and to controls, and to examine if severity of tendon pathology is associated with severity of symptoms during function.

Background: Despite the severity and chronicity of IAT, the quality of theoretical evidence available to guide the development of exercise interventions is low. While tendon pathology of midportion Achilles tendinopathy has been described, there are few studies specific to IAT.

Methods: Twenty individuals with unilateral IAT and 20 age- …

Analysis Of Knee Flexion Angles During 2 Clinical Versions Of The Heel Raise Test To Assess Soleus And Gastrocnemius Function, Kim Hébert-Losier, Anthony G. Schneiders, S John Sullivan, Richard J. Newsham-West, José A. García, Guy G. Simoneau

Physical Therapy Faculty Research and Publications

STUDY DESIGN: Controlled laboratory study, using a repeated-measures, counterbalanced design. OBJECTIVES: To provide estimates on the average knee angle maintained, absolute knee angle error, and total repetitions performed during 2 versions of the heel raise test. BACKGROUND: The heel raise test is performed in knee extension (EHRT) to assess gastrocnemius and knee flexion (FHRT) for soleus. However, it has not yet been determined whether select knee angles are maintained or whether total repetitions differ between the clinical versions of the heel raise test. METHODS: Seventeen healthy males and females performed maximal heel raise repetitions in 0° (EHRT) and 30° (FHRT) …

Variations In Emg Activity In Lower Leg Musculature With Use Of The Biomechanical Ankle Platform System (Baps), Carrie Carpenter, Andrea Lund, Jodi Sailer, Slinde Jessie

Physical Therapy Scholarly Projects

Ankle sprains account for 17% to 20% of all injuries in most sports. Other ankle conditions such as posterior tibialis tendon disorder and Achilles tendinosis are quite common in the nonathletic population and require many of the same interventions. Some of these interventions include range of motion, stretching, strengthening and proprioception. Many studies have shown that strength and proprioceptive training are the intervention of choice for those with lateral ankle instability. Many of these studies have supported the use of BAPS in improving proprioception among individuals with lateral ankle instability, however there is only one study examining the use of …

The Foot, Our Base Of Support, Sandra G. Lunde

Physical Therapy Scholarly Projects

The purpose of this independent study was to consolidate information on biomechanics of the foot and ankle and the possible effects on the rest of the body of faulty mechanics. A literature search and specialized continuing education contributed to improved working knowledge of the significance of variations of the normal biomechanics. The physical therapist relates to the patient through complaints of foot pain, or through foot evaluation to get to other sites of pain. A thorough evaluation process, shoe recommendations, stretching, and/or strengthening exercises, and orthotic evaluation are the results of study.
