Running Biomechanics Differ During And After Pregnancy Compared To Females Who Have Never Been Pregnant, Jennifer J. Bagwell, Elizabeth Avila, Nicholas Reynolds, Jo Armour Smith, Kevin Valenzuela, Dimitrios Katsavelis
Physical Therapy Faculty Articles and Research
Background
Perinatal running participation has increased recently; however, pregnancy related symptoms can limit activity. Perinatal running biomechanics could inform interventions to help perinatal individuals maintain an active lifestyle.
Research question
Are perinatal running biomaechanics and muscle activation different compared to nulligravida females?
Methods
Sixteen pregnant participants completed self-selected velocity running during second trimester (2 T), third trimester (3 T), and postpartum (PP) and 16 matched controls completed these procedures once in this case control study. Kinematic, kinetic, and electromyography (EMG) data were collected using a motion capture system, force plates, and EMG electrodes. Peak trunk, pelvis, hip, knee, and ankle …
An Exploratory Analysis Of Gait Biomechanics And Muscle Activation In Pregnant Females With High And Low Scores For Low Back Or Pelvic Girdle Pain During And After Pregnancy, Jennifer J.

Background
The purpose of this study was to compare gait kinematics, kinetics, and muscle activation between pregnant females with high and low scores for low back and/or pelvic girdle pain during and after pregnancy.
Methods
Twenty participants tested during second trimester, third trimester, and again post-partum. At each session, motion capture, force plates, and surface electromyography data were captured during self-selected velocity over-ground walking. Participants completed the Quebec Back Pain Disability Scale (QBPDS) and were assigned to high (QBPDS ≥15) or low pain groups (QBPDS
Findings
Nine participants met the high pain group criteria and 11 were low pain. During …
Comparison Of Pre- And Post-Operative Shoulder Muscle Emg Profiles In Reverse Total Shoulder Arthroplasty Patients, Emily Lau, Sreten Franovic, Noah Kuhlmann, Eric C. Makhni Md, Stephanie Muh Md
Comparison Of Pre- And Post-Operative Shoulder Muscle Emg Profiles In Reverse Total Shoulder Arthroplasty Patients, Emily Lau, Sreten Franovic, Noah Kuhlmann, Eric C. Makhni Md, Stephanie Muh Md
Medical Student Research Symposium
Background: Deltoid muscle function is central in reverse total shoulder arthroplasty (RTSA) function; however, there is limited information available regarding changes in deltoid activity before and after surgery. Few tests exist to evaluate specific muscle metrics pre and post operatively. Surface Electromyographic (EMG) is non-invasive and allows for observation of motions with multifaceted analysis of movement with minimal patient demand. Understanding the changes in shoulder muscle activation, namely in the deltoid, in patients pre and post-RTSA can further advance understanding of the procedure and rehabilitation efforts.
Methods: Nine individuals were recruited for this study: all patients underwent RTSA by a …
Individuals With Recurrent Low Back Pain Exhibit Significant Changes In Paraspinal Muscle Strength After Intramuscular Fine Wire Electrode Insertion, Szu-Ping Lee, Vincent Dinglasan, Anthony Duong, Russell Totten, Jo Armour Smith
Individuals With Recurrent Low Back Pain Exhibit Significant Changes In Paraspinal Muscle Strength After Intramuscular Fine Wire Electrode Insertion, Szu-Ping Lee, Vincent Dinglasan, Anthony Duong, Russell Totten, Jo Armour Smith

Objective
To examine how insertion and presence of intramuscular fine‐wire electromyography electrodes (IFWE) in lumbar multifidus affect paraspinal muscle strength, endurance, and activation in persons with and without recurrent lower back pain (RLBP) during activities that require high levels of muscle contraction.
Design
Case‐control with randomization of conditions.
Setting
Clinical Research Laboratory.
Participants
Forty participants age 18‐40 were recruited (18 female; mean age = 25.5 yr); 20 with a history of RLBP were compared to a matching control group of 20 without RLBP.
Interventions
Each participant was tested under three conditions over three sessions. On Session 1, the baseline condition, …
Neuromuscular Changes In Older Adults During The Lateral Step Task, Tatiana Bejarano
Neuromuscular Changes In Older Adults During The Lateral Step Task, Tatiana Bejarano
FIU Electronic Theses and Dissertations
Older adults may have trouble when performing activities of daily living due to decrease in physical strength and degradation of neuromotor and musculoskeletal function. Motor activation patterns during Lateral Step Down and Step Up from 4-inch and 8-inch step heights was assessed in younger (n=8, 24.4 years) and older adults (n=8, 58.9 years) using joint angle kinematics and electromyography of lower extremity muscles. Ground reaction forces were used to ascertain the loading, stabilization and unloading phases of the tasks. Older adults had an altered muscle activation sequence and significantly longer muscle bursts during loading for the tibialis anterior, gastrocnemius, vastus …
Time To Task Failure Differs With Load Type When Old Adults Perform A Submaximal Fatiguing Contraction, Sandra K. Hunter, Ludovic Rochette, Ashley Critchlow, Roger M. Enoka
Time To Task Failure Differs With Load Type When Old Adults Perform A Submaximal Fatiguing Contraction, Sandra K. Hunter, Ludovic Rochette, Ashley Critchlow, Roger M. Enoka
Exercise Science Faculty Research and Publications
Young adults exhibit a longer time to task failure when performing a submaximal isometric contraction by pushing against a force transducer (force task) than when supporting an equivalent inertial load (position task). The purpose of this study was to compare the time to failure for old adults when they performed a force task and a position task with the elbow flexor muscles. Eighteen old adults (72 ± 4 years) performed the force and position tasks at 20% maximal voluntary contraction (MVC) force until task failure. The time to task failure was briefer for the position task (10.6 ± 6.1 min) …
