Superficial cervical muscle activation in chronic neck pain
… background literature identified differences in muscle activation for individuals with chronic neck pain, following a whiplash injury and from a non traumatic onset, compared to healthy controls. However, differences in the combined action or synergy of superficial neck muscles in these chronic …

Muscle activation mapping of skeletal hand motion: an evolutionary approach.
… consists of mathe- matical modelling of muscles and solving the activation dynamics that form the key to coordination. But biomechanical simulation and control is com- putationally expensive involving complex di erential equations and is not suitable for real-time platforms like games. …

Time Varying Motion and Muscle Activation Patterns During Extreme Conditioning Protocols
… injury. This thesis aims to quantify changes in muscle activation, kinematics, and discomfort of the squat and deadlift exercises during an Extreme Conditioning Protocol. Twenty participants (minimum of 1 year experience, frequency of 2X/week) performed 5 sets of 8 deadlifts (60% 1RM), 8 front …

Muscle Activation Patterns and Chronic Neck-Shoulder Pain in Computer Work
… interventions targeting this issue. Static muscle contractions for prolonged periods often occur in the neck/shoulder during computer work and may underlie muscle pain development in spite of rather low relative muscle load levels. Causal mechanisms may include a stereotypical recruitment of …

The influence of trunk inclination on lower limb moments and muscle activation patterns
… by altered joint moments, increased knee muscle activity and increased muscular co-contraction. Modelling studies suggest that such altered muscle patterns may increase the loading on knee joint, with imaging studies suggesting that co-contraction may accelerate cartilage loss. …

Ergonomic evaluation of shoulder muscle activation during light weight hand tool exertion task
… was conducted to evaluate the effect of shoulder muscle activation during hand exertion tasks using a light weight hand tool by working individuals. Electromyography (EMG) of trapezius, supraspinatus, triceps, and pectoralis major was conducted for 45 , 0 and -45 arm angles, for three different …

Characteristics of muscle activation patterns at the ankle in stroke patients during walking.
… Efficient gait requires a complex interplay of muscles. Surface electromyography(sEMG) can be used to measure muscle activity and to observe disruption to this interplay after stroke. Yet, classification of this disruption in stroke patients has not been achieved. It is hypothesised that …

Using sEMG to investigate muscle activation during a graded exercise test while sustaining SRC
… research has explored the impact of SRCs on muscle activation patterns during exercise. This study aimed to investigate differences in normalized LE muscle activity in collegiate athletes with SRC during the acute phase of injury compared to their symptom-free state. Surface electromyography …

Effect of rotator cuff muscle fatigue on shoulder muscle activation and posture during driving
Rotator cuff (RC) muscle dysfunction impacts the ability to perform daily functional tasks, such as driving. It has been suggested that RC muscle fatigue can mimic rotator cuff tears (RCT) during sudden steering in terms of kinematics. It has also been found that two RC muscles (infraspinatus and …

Muscle Activation During High and Low Intensity Strength Training In Older Adults With Knee Osteoarthritis
Introduction: Muscle weakness is a common impairment in the knee osteoarthritis (OA) population that is partially due to an impairment in the central nervous systems ability to activate a muscle fully. The effect of resistance training intensities on muscle activation in the knee OA population has …

Lower Extremity Muscle Activation Following a Previous Knee Injury: Implications for Post-Traumatic Knee Osteoarthritis
… (PTOA) 10-20 years later. Compensatory activation patterns of knee muscles in response to the trauma may persist past the acute injury phase and result in abnormal mechanical loading and subsequent osteoarthritis of the knee. This dissertation aimed to use surface electromyography (sEMG) …

The Effect of Sternocleidomastoid Muscle Activation Pattern and Feedback Condition on the Vestibular Evoked Myogenic Potential.
… tonically contracted sternocleidomastoid (SCM) muscle. Because the VEMP is an inhibitory response, it is important to investigate stimulus and parameter characteristics in order to determine the optimal test protocol and maximize clinical usefulness. The aims of this study were 1) to evaluate …

The biomechanical effect of trunk inclination on joint moments and muscle activation in people with knee osteoarthritis
… by altered joint moments, increased muscle activity and increased muscular co-contraction. Furthermore, modelling studies have shown that the alterations in muscle patterns that are characteristic of knee OA lead to elevated joint loads, while longitudinal studies have demonstrated …

Acute Responses of Muscle Activation during Eccentric Accentuated Loaded Squats and Normal Loaded Squats in Collegiate Weightlifters
… to optimize adaptations to force production and muscle mass via acute postactivation potentiation (PAP). Though enhancement of performance variables via AEL or PAP is equivocal in the literature, it is understood that AEL and/or PAP will result in either positive adaptations or a lack of …

Traumatic brain injuries and older adults: The implications of neck strength, muscle activation, and range of motion
… active and passive range of motion, and neck muscle activation latency in response to postural perturbation in 57 participants. Participants were divided based on age with 20 Young (18 – 30 years old), 23 Young-Old (60 – 74 years old), and 14 Old-Old (75 – 89 years old) adults being included. …
