Exploring the Design of Upper Limb Strength Training Through High-Intensity Interval Training Combined With Exergaming: Usability Study

Exploring the Design of Upper Limb Strength Training Through High-Intensity Interval Training Combined With Exergaming: Usability Study

After the MVC testing, electromyography (EMG) electrodes were placed on the skin over the belly of the tested muscles for subsequent signal recording and analysis. (A) Standardized illustrations for the MVC action of each muscle. (B) MVC sensor placement for each muscle. MVC: maximal voluntary contraction.

Efficacy of Naprapathy in Brachial Plexus Injury: Protocol for a Randomized Clinical Trial

Efficacy of Naprapathy in Brachial Plexus Injury: Protocol for a Randomized Clinical Trial

The inclusion criteria are as follows: (1) aged 18 to 70 years; (2) BPI diagnosed by history, physical examination, electromyography, or surgical exploration more than 2 weeks after nerve surgery; (3) agreement to provide written informed consent.

Bispectral Index Alterations and Associations With Autonomic Changes During Hypnosis in Trauma Center Researchers: Formative Evaluation Study

Bispectral Index Alterations and Associations With Autonomic Changes During Hypnosis in Trauma Center Researchers: Formative Evaluation Study

Several studies have documented the effects of hypnosis on skin conductance, expired carbon dioxide, respiratory rate, electromyography (EMG), and skin temperature values. Two relatively recent studies have demonstrated that hypnosis is associated with reductions in skin conductance values [8,29]. We found that only a single study investigated expired carbon dioxide measurements during hypnosis [30].

Walking With a Robotic Exoskeleton Does Not Mimic Natural Gait: A Within-Subjects Study

Walking With a Robotic Exoskeleton Does Not Mimic Natural Gait: A Within-Subjects Study

The 10 surface electrode pairs were affixed with self-adhesive tape on the specific location for each muscle following the Surface Electro Myo Graphy for the Non-Invasive Assessment of Muscles [18] recommendation to minimize surface myoelectric signal cross-talk [19]. Prior to electrode placement, the patient’s skin in the areas of electrode placement was cleaned with isopropyl alcohol.

Identifying Subgroups of Patients With Chronic Nonspecific Low Back Pain Based on a Multifactorial Approach: Protocol For a Prospective Study

Identifying Subgroups of Patients With Chronic Nonspecific Low Back Pain Based on a Multifactorial Approach: Protocol For a Prospective Study

Alterations were also found in the trunk and hip muscle surface electromyography (s EMG). Nonspecific chronic LBP subjects presented with higher global trunk muscle activity during gait [35] or lifting tasks [36]. Many studies highlighted an exacerbated lumbar erector spinae activity (absence of the flexion-relaxation phenomenon) at full trunk forward flexion [37-39]. Nonspecific chronic LBP patient subgroups have previously been identified based on biomechanical parameters.

Patient Transfers and Risk of Back Injury: Protocol for a Prospective Cohort Study With Technical Measurements of Exposure

Patient Transfers and Risk of Back Injury: Protocol for a Prospective Cohort Study With Technical Measurements of Exposure

These technical measurements, using surface electromyography (EMG) and accelerometers to quantify muscle activity and body movements, respectively, will allow for identification of the biomechanical characteristics of various patient transfers.
