879 www.e-arm.org We appreciate your interest in our study. In this study, we did not focus on lumbar extensor strength. Our interventions were consisted of trunk extensor, flexor, and rotator muscles strength. Isolated lumbar extensor strengthening machine MedX (MedX Holdings Inc., Ocala, FL, USA) was used to compare superficial muscles of trunk and deep spinal muscles strength between baselin...

Mechanical and neurological couplings exist between musculotendon units of the human hand and digits. Studies have begun to understand how these muscles interact when accomplishing everyday tasks, but there are still unanswered questions regarding the control limitations of individual muscles. Using intramuscular electromyographic (EMG) electrodes, this study examined subjects' ability to indiv...

BACKGROUND Frequently using non-slanted computer mice will cause musculoskeletal discomfort and symptoms in forearms and shoulders. Ergonomic mice with different slanted angles may have various effects on forearm and shoulder muscle activity. METHODS All of the twelve subjects performed the same text-editing task with the five different slanted mice. The muscle activity of extensor carpi ulna...

OBJECTIVE To compare the EMG activity between the recti abdominii muscles and between the lumbar erector spinae muscles in hemiparetic and hemiplegic patients during functional symmetric trunk movements and to compare patients' EMG activity profiles with those of healthy controls. METHODS EMG activity from the selected muscles was recorded during three symmetric and time controlled trunk exer...

Biologists have traditionally focused on a muscle's ability to generate power. By determining muscle length, strain and activation pattern in the cockroach Blaberus discoidalis, we discovered leg extensor muscles that operate as active dampers that only absorb energy during running. Data from running animals were compared with measurements of force and power production of isolated muscles studi...

STUDY DESIGN Cross-sectional investigation of muscle changes in patients suffering from persistent whiplash-associated disorders (WAD). OBJECTIVES To quantitatively compare the presence of fatty infiltrate in the cervical extensor musculature in a cohort of chronic whiplash patients (WAD II) and healthy control subjects across muscle and cervical segmental level. SUMMARY OF BACKGROUND DATA ...
