A Levitate Airframe exoskeleton fits like a backpack frame with elbow cuffs that support arm weight during overhead shoulder postures. The purpose of this study was to test this passive shoulder support exoskeleton during on-site job tasks. Six experienced workers in assembly (three workers), painting, parts hanging, and welding at two John Deere manufacturing sites volunteered for this study. ...

BACKGROUND Prone, supine, and side position exercises are employed to enhance core stability. HYPOTHESIS Overall core muscle activity would be greater in prone position exercises compared with supine and side position exercises. STUDY DESIGN Controlled laboratory study. METHODS Eighteen men and women between 23 and 45 years of age served as subjects. Surface electrodes were positioned ove...

Antony Stewart was the main author. He designed the protocol and piloted and modified the forms used for assessment of eligibility, validity and data extraction. He undertook searches for studies and requested further information from authors. He liaised with content experts in the field to obtain background information and support. He assessed studies for eligibility, validity and extracted da...

INTRODUCTION Women with fibromyalgia (FM) have symptoms of increased muscular fatigue and reduced exercise tolerance, which may be associated with alterations in muscle microcirculation and oxygen metabolism. This study used near-infrared diffuse optical spectroscopies to noninvasively evaluate muscle blood flow, blood oxygenation and oxygen metabolism during leg fatiguing exercise and during a...

Background: Running has many health benefits and has therefore become a sport with an expanded popularity worldwide. With it comes an increased incidence of overuse injuries, and there is a constant debate whether the shoes a runner uses should be as supportive as possible or minimalistic in order to facilitate a more natural running pattern. Many running retail outlets use video analysis to fi...

 Postural disorders disrupt muscle activity and lead to joint dysfunction. Maintaining the function of the shoulder joint requires precise coordination and on-time action of muscles, and its dysfunction lead to change in the level of muscle activity, movement disorder. This study aimed to measure the effects of corrective exercise program with kinesiotaping and physio-ball and durability of the...

Objectives: Blood Flow Restriction (BFR) training provides partial occlusion at the proximal upper and lower extremities has been shown to improve muscular strength hypertrophy following an injury or surgery. By eliciting hypoxic intramuscular conditions, we can stimulate adaptive processes in skeletal muscle a similar manner high intensity resistance but substantially safer exercise workloads ...

No data exist on the electromyography (EMG) responses in children exposed to dynamic impacts and the resulting head and neck kinematics. The objective of the current study was to measure the EMG responses of the neck, torso and lower extremity in children and young adults during a low speed frontal impact using surface electrodes bilaterally and compare these muscle responses to key kinematic e...
