Assessment Of Postural, Locomotor, And Physical Fitness Status In Individuals With Intellectual And Developmental Disabilities, Alana J. Turner Aug 2022

Assessment Of Postural, Locomotor, And Physical Fitness Status In Individuals With Intellectual And Developmental Disabilities, Alana J. Turner

Theses and Dissertations

Introduction: Postural control and locomotion deficits can be observed during the early years of childhood development and throughout life. For those with disabilities, these deficits can advance past the development years and into adolescence and adulthood while affecting the quality of life and daily activity. Finding interactive rehabilitative activities to delay or limit these deficits is essential for people with disabilities to improve their quality of life, inclusion, and overall movement. Adapted physical activity/sports like badminton and virtual reality could promote improvements in postural and locomotor status for young adults with intellectual and developmental disabilities like cerebral palsy (CP), intellectual …

The Effects Of A 6-Week Intrinsic Foot Morphology, Kinematics, And Kinetics In Individuals With Pes Planus, Rebecca Marszalek, Janet E. Simon, Robert Wayner

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

CONTEXT
The intrinsic foot muscles are vital in supporting the medial longitudinal arch of the foot. Individuals with pes planus have poor foot morphology, strength, and biomechanics, warranting an intervention.

MAIN OUTCOME MEASURES
At pre-intervention, foot posture and arch height were assessed via the Foot Posture Index-6 and the Navicular Drop test, respectively. Cross-sectional area of the abductor hallucis was assessed using ultrasound as an indirect measure of strength. Biomechanical measures, including peak rearfoot eversion, peak tibial internal rotation, peak rearfoot eversion moment, and center of pressure excursion, were collected using 3D-motion capture and an instrumented treadmill. At post-intervention, these …

Development And Application Of 3d Kinematic Methodologies For Biomechanical Modelling In Adaptive Sports And Rehabilitation, Anne Marie Severyn

All Dissertations

Biomechanical analysis is widely used to assess human movement sciences, specifically using three-dimensional motion capture modelling. There are unprecedented opportunities to increase quantitative knowledge of rehabilitation and recreation for disadvantaged population groups. Specifically, 3D models and movement profiles for human gait analysis were generated with emphasis on post-stroke patients, with direct model translation to analyze equivalent measurements while horseback riding in use of the alternative form of rehabilitation, equine assisted activities and therapies (EAAT) or hippotherapy (HPOT). Significant improvements in gait symmetry and velocity were found within an inpatient rehabilitation setting for patients following a stroke, and the developed movement …

Background

The biomechanics of the trunk and lower limbs during walking and running gait are frequently assessed in individuals with low back pain (LBP). Despite substantial research, it is still unclear whether consistent and generalizable changes in walking or running gait occur in association with LBP. The purpose of this systematic review was to identify whether there are differences in biomechanics during walking and running gait in individuals with acute and persistent LBP compared with back-healthy controls.

Methods

A search was conducted in PubMed, CINAHL, SPORTDiscus, and PsycINFO in June 2019 and was repeated in December 2020. Studies were included …

Muscle-Specific Contributions To Lower Extremity Net Joint Moments While Squatting With Different External Loads, Kristof Kipp, Hoon Kim, William I. Wolf

Exercise Science Faculty Research and Publications

The purpose of this study was to determine muscle-specific contributions to lower extremity net joint moments (NJMs) during squats with different external loads. Nine healthy subjects performed sets of the back squat exercise with 0, 25, 50, and 75% of body mass as an added external load. Motion capture and force plate data were used to calculate NJMs and to estimate individual muscle forces via static optimization. Individual muscle forces were multiplied by their respective moment arms to calculate the resulting muscle-specific joint moment. Statistical parametric mapping (α = 0.05) was used to determine load-dependent changes in the time series …

Occupation-Centered Anatomy And Applied Biomechanics Courses: Design And Outcomes, Rose Mcandrew, Vicki K. Kaskutas Jan 2022

Occupation-Centered Anatomy And Applied Biomechanics Courses: Design And Outcomes, Rose Mcandrew, Vicki K. Kaskutas

Journal of Occupational Therapy Education

Occupation-centered course design allows occupational therapy (OT) educators to differentiate ourselves from other professions while communicating the distinct value of occupation to our students. While there have been numerous calls to action for centering occupation in the OT classroom and proposed models to approach course design, there is limited literature on occupation-centered course design in specific courses, notably foundational science courses like anatomy and applied biomechanics. In this study, we outline our course design process in two courses taught concurrently, as well as our prospective study to determine if an occupation-centered course design allowed students to meet objectives and the …


Maximal Strength In Relation To Force And Velocity Patterns During Countermovement Jumps, Michael H. Haischer, John Krzyszkowski, Stuart Roche, Kristof Kipp Jan 2022

Maximal Strength In Relation To Force And Velocity Patterns During Countermovement Jumps, Michael H. Haischer, John Krzyszkowski, Stuart Roche, Kristof Kipp

Exercise Science Faculty Research and Publications

Maximal strength is important for the performance of dynamic athletic activities, such as countermovement jumps (CMJ). Although measures of maximal strength appear related to discrete CMJ variables, such as peak ground reaction forces (GRF) and center-of-mass (COM) velocity, knowledge about the association between strength and the time series patterns during CMJ will help characterize changes that can be expected in dynamic movement with changes in maximal strength. Purpose: To investigate the associations between maximal strength and GRF and COM velocity patterns during CMJ. Methods: Nineteen female college lacrosse players performed 3 maximal-effort CMJs and isometric midthigh pull. GRF …

Physical Therapy Faculty Research and Publications

Osteoarthritis development after ACL reconstruction (ACLR) is not well understood. Investigators have examined associations between knee biomechanical alterations and quantitative MRI (qMRI) variables, reflective of cartilage health, 12–60 months following ACLR; however, none have done so early after surgery. As part of an exploratory study, 45 individuals (age, 23 ± 7 years) underwent motion analysis during walking and qMRI 3 months after ACLR. For each limb, peak knee adduction moment (pKAM) and peak knee flexion moment (pKFM) were determined using inverse dynamics and peak medial compartment force was calculated using a neuromusculoskeletal model. T2 relaxation times in the medial …
