Characterization of Quadriceps Neuromuscular Function in Knee Osteoarthritis
… of this thesis was to characterize quadriceps neuromuscular dysfunction in patients with knee osteoarthritis (OA). Concerns pertaining to study design in this patient population (e.g. disease severity criteria and muscle imaging outcome measures) were also addressed. METHODS: Five studies were …

Dynamic Upper Leg Strength and Neuromuscular Function in Children, Adolescents and Adults
… muscle strength, muscle performance, and neuromuscular function during contractions at different velocities across maturation stages and between sexes. Participants included pre-pubertal, late-pubertal and adult males and females. All completed 8 isometric and 8 isokinetic leg extensions …

TRANSLATIONAL APPROACH TO NEUROMUSCULAR FUNCTION AND ITS RECOVERY: EFFECT OF LIMBS, AGING, AND DISEASE.
… during exercise can ultimately determine neuromuscular function fatigability. Furthermore, the time course of neuromuscular function recovery after exercise is essential for planning repeated daily activities and sports. My PhD work aimed to compare the effects of different fatiguing …

Exploiting Caenorhabditis elegans as a Discovery Platform to Identify Nematode Parasiticides that Act Through Neuromuscular Disruption
… parasiticides developed to date act through neuromuscular disruption. this is an effective strategy as several behaviours that are essential for maintaining a state of parasitism including feeding, reproduction, and attachment to host tissues rely on neuromuscular function. The non-parasitic …

Neuromuscular Adaptations to Training in Children with Cerebral Palsy
… of various therapeutic approaches on motor function in children with CP, the neuromuscular mechanisms that underpin motor function improvements remain poorly understood. The overarching goal of this PhD was therefore to enhance the understanding of the underlying neuromuscular adaptations to …

A minimalistic model of resistance training : effects on skeletal muscle function during unloading
… extensor and plantar flexor size, strength and neuromuscular function in response to unloading. A total of 32 subjects participated. Sixteen men underwent 21 days of unilateral lower limb suspension (ULLS) and were assigned to control (no RTP) (ULLS-CON, n=8) or countermeasures (ULLS-CM, n=8). …

Quantifying neuromuscular performance of elite rugby union players: Measurement characteristics and moderating factors
This thesis investigates the neuromuscular status of elite rugby union players through longitudinal countermovement jump (CMJ) monitoring. A systematic and agnostic framework for selecting CMJ metrics is proposed, integrating reliability, sensitivity, and covariance considerations. Over four …

Alterations in neck muscle performance and proprioception with fatique, altered posture and recurrent neck pain
Altered neuromuscular processing and motor output as both a risk and perpetuating factor for chronic neck pain is a relative new area of study. The cervical flexion relaxation response (FRR) is a reproducible and reliable marker of differences in neuromuscular function between neck pain patients …

Using sEMG to investigate muscle activation during a graded exercise test while sustaining SRC
… phase of injury. While SRCs are known to disrupt neuromuscular function and increase the risk of lower extremity (LE) injuries, limited research has explored the impact of SRCs on muscle activation patterns during exercise. This study aimed to investigate differences in normalized LE muscle …

Understanding the gender-based mechanism of mso in als mice: a metabolic characterization of the sod1-g93a mouse model
… motor neuron death and a corresponding loss of neuromuscular connections resulting in muscle atrophy. Patients become paralyzed shortly after symptom onset and typically die within one to five years of pulmonary complications. ALS is a relatively rare disease, with an overall incidence of …

DECODING MUSCLE EXCITATION IN RESISTANCE TRAINING: A HIGH-DENSITY SEMG APPROACH
… training (RT) is a primary stimulus for neuromuscular and structural adaptations, yet the characterization of muscle excitation during RT remains limited by methodological constraints. Traditional surface electromyography (sEMG) provides a global estimate of muscle activity but lacks the …

Manipulating dietary protein density and its effect on training-induced muscle performance and overall health among middle-aged adults
… to alterations in overall muscle mass and neuromuscular function. It has been proposed that lifestyle modifications to include exercise training and higher dietary protein intakes will likely be the most effective approach to offset muscle strength loss with advancing age. Thus, the study …

VERT-Derived Jump Volume and Intensity Related to Functional Movement Quality in Female Collegiate Volleyball Players
… increased injury risk, along with decreased neuromuscular function, motor control, and joint mobility. This study aims to investigate the relationship between jump metrics measured using the VERT Team System and functional movement quality assessed using three NASM transitional movement …

Evaluation of Global Muscle Innervation Using Multi-Channel Surface Electromyography
… have enabled the non-invasive assessment of neuromuscular function at the muscle and motor unit level. Specifically, sEMG has been used to assess the location of innervation zones (IZs) and the quantity of functioning innervation of targeted muscles. This knowledge associated with muscle …

Neuromuscular Dysfunction as a Novel Indicator for Alzheimer's Disease and Response to Intervention in the 5xFAD Model
… AD is often associated with decreased muscle function and mitochondrial respiration, but the cause of these peripheral phenotypes in a brain disease remains unclear. Exercise promotes muscle, mitochondrial, and cognitive health, and is proposed as a potential therapeutic for AD. This study …

An examination of age-related differences in lower extremity joint torques and strains in the proximal femur during gait
… performed to investigate age-related changes in neuromuscular function during gait and how these changes affect strains in the proximal femur. Study 1 examined age differences in peak lower extremity joint torques during walking with controlled speed and step length. Studies 2 and 3 applied …

Central and peripheral determinants of fatigue in acute hypoxia
… 93-80%) were determined. Hypoxia did not alter neuromuscular function or cortical voluntary activation of the knee-extensors at rest, despite large reductions in cerebral oxygenation. Maximal force declined by ~30% after single-limb exercise in all conditions, despite reduced exercise time in …

Functional Anatomy of the Anconeus: Muscle Architecture and Motor Unit Number Estimation
… have important implications related to the neuromuscular function of this muscle as a model for study in health and disease. The two studies presented in this thesis investigate the functional anatomy of the anconeus in 10 healthy young men (25±3y). Ultrasound imaging has facilitated the …
