Electro-chemical stimulation of neuromuscular systems using ion-selective membranes : flexible device fabrication and motor unit recruitment order
… and by high fatigability due to the reversal of recruitment order of motor units. Previous work showed that ion-selective membranes can be used to modulate Ca 2 ions in situ, decreasing the current threshold for nerve stimulation and eliciting a more graded muscle contraction response. This work …

Acute effects of self-myofascial release and static stretching on shoulder range of motion and performance in overhead athletes with glenohumeral internal rotation deficit
… external rotation isometric strength, motor unit recruitment, and throwing velocity) in male softball players with glenohumeral internal rotation deficit (GIRD).</p> <p>Methods: The sample consisted of 12 male amateur softball players (age: 36.92 ±11.17 years; height: 177.42 ±6.30cm; …

The Neuromuscular and Mechanical Control of the Knee Joint in Patellofemoral Pain Sufferers
Results Grouped Tape Response: The mean motor unit firing exhibited an increase in the VM firing rate and a decrease in the VL firing rate within the tape condition, across both subject groups, suggesting a modification in the load bias across the Vasti muscles. The common drive, a physiological …

EMG Threshold Detection and Reliability of Boys and Men Using an Isometric Contraction Protocol
… utilize more of their higher-threshold (type II) motor units (MU). Such developmental changes in MU utilization can potentially underlie many observed physiological differences between children and adults. The EMG threshold (EMGTh¬) is a proposed non-invasive tool to investigate the recruitment of …

Muscle Activation Patterns and Chronic Neck-Shoulder Pain in Computer Work
… Causal mechanisms may include a stereotypical recruitment of low threshold motor units (activating type I muscle fibers), characterized by a lack of temporal as well as spatial variation in motor unit recruitment. Based on this theory, although studies have postulated that individuals with …

Characterisation of cardiorespiratory responses to electrically stimulated cycle training in paraplegia
… of a fibre hypertrophy within the stimulated motor units. The relationship that was found between variables after this time suggest that differences in the efficiency of FES cycling ii between subjects and over time related primarily to the stim/Pt, which determined the number of motor units …

Comparison of acute physiological effects between alternating current and pulsed current electrical muscle stimulation
Electrical muscle stimulation (EMS) is widely used in rehabilitation and sport training, and alternating current and pulsed current EMS are commonly used. However, no systematic comparison between alternating and pulsed current EMS has been made in the previous studies. The main aim of this …
