Muscle Activation Patterns During Movement Attempts In Children With Acquired Spinal Cord Injury: Neurophysiological Assessment Of Residual Motor Function Below The Level Of Lesion., Darryn A Atkinson, Laura Mendez, Natalie Goodrich, Sevda C Aslan, Beatrice Ugiliweneza, Andrea L Behrman

Physical Therapy Collection

Introduction: Characterization of residual neuromotor capacity after spinal cord injury (SCI) is challenging. The current gold standard for measurement of sensorimotor function after SCI, the International Society for Neurological Classification of Spinal Cord Injury (ISNCSCI) exam, seeks to determine isolated intentional muscle activation, however many individuals with SCI exhibit intentional movements and muscle activation patterns which are not confined to specific joint or muscle. Further, isolated muscle activation is a feature of the neuromuscular system that emerges during development, and thus may not be an appropriate measurement standard for children younger than 6.

Methods: We utilized neurophysiological assessment …

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

Physical Therapy Faculty Articles and Research

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, …

Hip And Trunk Muscle Activity During The Star Excursion Balance Test In Healthy Adults, Kunal Bhanot, Navpreet Kaur, Lori Thein Brody, Jennifer Bridges, David C. Berry, Joshua J. Ode

Physical Therapy Collection

CONTEXT: Dynamic balance is a measure of core stability. Deficits in the dynamic balance have been related to injuries in the athletic populations. The Star Excursion Balance Test (SEBT) is suggested to measure and improve dynamic balance when used as a rehabilitative tool.

OBJECTIVE: To determine the electromyographic activity of the hip and the trunk muscles during the SEBT.

DESIGN: Descriptive.

SETTING: University campus.

PARTICIPANTS: Twenty-two healthy adults (11 males and 11 females; 23.3 [3.8] y, 170.3 [7.6] cm, 67.8 [10.3] kg, and 15.1% [5.0%] body fat).

INTERVENTION: Surface electromyographic data were collected on …

Neuromuscular Adaptions Following A Daily Strengthening Exercise In Individuals With Rotator Cuff Related Shoulder Pain: A Pilot Case-Control Study, Amee L. Seitz, Lisa A. Podlecki, Emily R. Melton, Timothy L. Uhl

Physical Therapy Faculty Publications

Background: The goal of therapeutic exercise is to facilitate a neuromuscular response by increasing or decreasing muscular activity in order to reduce pain and improve function. It is not clear what dosage of exercise will create a neuromuscular response.

Purpose: The purpose of this study was to assess the effects following a three-week home program of a daily single exercise, the prone horizontal abduction exercise (PHA), on neuromuscular impairments of motor control as measured by scapular muscle EMG amplitudes, strength, and secondarily outcomes of self-reported pain and function between individuals with and without subacromial pain syndrome.

Study Design: Prospective Case-Control, …

The Effects Of Cryotherapy On Quadriceps Electromyographic Activity And Isometric Strength In Patient In The Early Phases Following Knee Surgery, William Loro, Mark Thelen, Michael Rosenthal, Paul Stoneman, Michael Ross

Articles & Book Chapters

Purpose: To determine the effects of cryotherapy on quadriceps electromyographic (EMG) activity and isometric strength in early postoperative knee surgery patients.

Methods: Twenty-two volunteers with recent knee surgeries were included. EMG readings of the vastus medialis (VM), rectus femoris (RF), and vastus lateralis (VL) from the surgical leg were collected during a maximal voluntary quadriceps setting (QS) activity. Maximum isometric knee extension force measurements were also recorded. Subjects were randomly assigned to receive an ice bag or a sham room-temperature bag to the front of their postsurgical knee for 20 min. After treatment, the subjects repeated the above mentioned maximum …

Walking With A Robotic Exoskeleton Does Not Mimic Natural Gait: A Within-Subjects Study, Chad Swank, Sharon Wang-Price, Fan Gao, Sattam Almutairi

Kinesiology and Health Promotion Faculty Publications

Background: Robotic exoskeleton devices enable individuals with lower extremity weakness to stand up and walk over ground with full weight-bearing and reciprocal gait. Limited information is available on how a robotic exoskeleton affects gait characteristics.

Objective: The purpose of this study was to examine whether wearing a robotic exoskeleton affects temporospatial parameters, kinematics, and muscle activity during gait.

Methods: The study was completed by 15 healthy adults (mean age 26.2 [SD 8.3] years; 6 males, 9 females). Each participant performed walking under 2 conditions: with and without wearing a robotic exoskeleton (EKSO). A 10-camera motion analysis system synchronized with 6 …
