Mri-Based Estimation Of The Hip Joint Center In Infants Using Two Sphere-Fitting Methods, Victoria Melendez

Discovery Day - Daytona Beach

Accurate estimation of the hip joint center (HJC) is critical for biomechanical modeling and clinical assessment. Common methods include predictive methods (e.g., regression equations) and functional methods such as sphere-fitting. In infants, femoral head-based methods are often limited due to incomplete ossification of the anatomy and poor visualization in computed tomography (CT) images. This study evaluates an alternative approach using MRI-based sphere fitting of the ossified acetabular rim, comparing its accuracy to traditional femoral head-based methods. MRI scans of three male infants (ages 10.7- 12.7 months) were used to manually place landmarks on the ossified acetabulum and the cartilaginous boundary …

The Osteocyte-Osteoblast Network Requires Dynamic Mechanical Loading For Key Functions, Kevin Kowalski

Discovery Day - Daytona Beach

Spaceflight investigations have demonstrated that reduction in gravity-induced loading regimes is detrimental to maintenance Earth-normal bone and marrow. Mechanistically, however, there are still gaps in knowledge about how the reduction in gravity influences the different niches within the tissue. For example, cortical bone is a stable semi-solid structure that allows for only minor deformations before failure, while marrow is a viscous hydrogel-like material that can resist significant fluidic and compressive forces. We hypothesize that maintenance of different niches within the bone microenvironment are dependent on different loading regimes, and that the collective impact if gravity-induced loading needs to be considered …

Impact Of Inspiratory Muscle Training On Diaphragm Hypertrophy, Exercise Performance, And Immune Response, Riley Dienna, Sabrina Ehrenfort, Joshua Frankenfield, Olivia Hartmann, Ben Kerns, Gianpiero Lara, Meliah Martin, Emma Norris, Louis Pandolfo, Rachel Phillips, Stella Roane, Dominic Sandell, Sabrina I. Santini-Bousson, Madison Stroud, Cecilia Zoutewelle, Erica Bryant

Discovery Day - Daytona Beach

The muscles involved in breathing, notably the diaphragm and intercostal muscles, play a role in determining the exercise capability of an individual. These muscles perform the work required for breathing, and as exercise intensity increases these muscles increase their activity to allow the respiratory system to meet the increased metabolic demands of exercise. Fatigue of these muscles reduces exercise tolerance and performance. In addition, the inflammation caused by acute maximal exercise is impacted by the level of training of the individual, and thus, inspiratory muscle training (IMT) may impact the inflammation due to exercise. We will test the hypothesis that …

Stability And Mobility: A Lesson From The Body, For The Body, Marc Apkarian

CSKLS Annual Conference

ABSTRACT

Whether for activities of daily living, occupation, or sport and exercise, coordinated, orchestrated movement of the body is necessary for meaningful function and motion. The musculoskeletal system is responsible for facilitating functional movement, while ensuring stability and mobility in associated regions of the body. Stability concerns itself with the ability to maintain control of joint movement or positioning, whereas mobility has to do with the ability to facilitate coordinated, unrestricted movement.

In functional movement training, a popular refrain often heard is “proximal stability aids distal mobility”. This suggests that good musculoskeletal stability in the core of the body (near …
