STUDY DESIGN An axial rotation tester was designed and fabricated for the study. This allowed stabilization of seated subjects (hip down) and coupling of shoulders, permitting axial rotation and coupled lateral flexion. Using this device, a "flexion-extension free" axial rotation was executed for studying its characteristics. OBJECTIVES To determine the(More)
Electromyographic (EMG) patterns of the trunk muscles were investigated during balance perturbations in a sitting position. Five healthy subjects (two females and three males, mean age 24.4 yr) were seated on a platform allowing rotational perturbations in the frontal and sagittal planes. Each of the forward, backward, right and left perturbations were(More)
OBJECTIVES To measure the cervical isometric force generation capacity of men and women reliably while seated in upright neutral posture. DESIGN The cervical muscle isometric strength was determined in flexion, extension, lateral flexion, anterolateral flexion and posterolateral extensions in an upright seated neutral posture. For this measurement a(More)
The purpose of the current study was twofold: (1) to determine the isometric force and electromyographic (EMG) relationship of the sternocleidomastoid, splenii and trapezii muscles bilaterally in graded and maximal exertions in the sagittal, coronal and oblique planes. and (2) to develop regression equations to predict force based on the EMG scores. A newly(More)
Effect of the self-monitoring approach on exercise maintenance during cardiac rehabilitation: A randomized, controlled trial. Objective: To evaluate the effect of the self-monitoring approach (SMA) on self-efficacy for physical activity (SEPA), exercise maintenance, and objective physical activity level over a 6-mo period after a supervised 6-mo cardiac(More)
OBJECTIVES To determine the forearm muscles activity in different wrist deviated positions and wrist neutral zone, and to assess the self-selected resting position without visual feedback. BACKGROUND Wrist deviation occurs in almost all industrial and office jobs. This has been deemed hazardous for carpal tunnel syndrome. Proper resting wrist position is(More)
Forty normal young adults volunteered for an experiment in which they were required to perform two-handed maximal pull-push in isometric and isokinetic modes (50 cm/s linear velocity of the handle) at 50-, 100-, and 150-cm heights of handle in sagittal, 30-deg lateral, and 60-deg lateral planes. Subjects were stabilized on a circular platform that rotated(More)
Static program analysis is widely used in property checking of software systems, especially safety and mission critical embedded systems. Most of these efforts check for violation of only standard properties such as array index out of bound, overflow/underflow and so on. However, our studies have shown that checking for these standard properties only(More)
This study was conducted to determine the pattern, magnitude, and phasic inter-relationship of the trunk muscles in maximal isometric and graded isometric axial rotational contractions and compare them with those previously observed from the same subjects in the same experimental session in dynamic conditions. In 50 normal young healthy subjects (27 male(More)
