We have studied the formation of a resistive region in the capillary during DNA separation. This effect is caused by an unequal change in the mobilities of cations and anions at the interface between the running buffer solution and the capillary. We studied the motion of the resistive region boundary by sequential removal of portions of the affected capillary end. We found that in the process o...

OBJECTIVE To examine whether robotic therapy can reduce motor impairment and enhance recovery of the hemiparetic arm in persons with chronic stroke. DESIGN Pre-posttest design. SETTING Rehabilitation hospital, outpatient care. PARTICIPANTS Volunteer sample of 20 persons diagnosed with a single, unilateral stroke within the past 1 to 5 years, with persistent hemiparesis. INTERVENTIONS Ro...

Analyses of Power Output of Piezoelectric Energy Harvesting Devices Directly Connected to a Resistive Load Using a Coupled Piezoelectric-Circuit Finite Element Method Meiling Zhu, Emma Worthington and James Njuguna Department of Materials, Department of Sustainable Systems Cranfield University, Bedfordshire, MK43 0AL UK Abstract A coupled piezoelectric-circuit finite element model (CPC-FEM) is ...

This study assesses the safety of and physiologic responses to maximal repetition, dynamic, resistive weight lifting at 40, 60, 80 and 100% of maximal voluntary contraction compared with aerobic exercise using a maximal treadmill exercise test. Twelve men with coronary artery disease exercised to fatigue at 4 stations (overhead press, biceps curl, quadriceps extension and supine press). The ele...

The purpose of this study was to investigate the effects of a 6-week scapular upward rotation exercise (SURE) on scapular and clavicular alignment and scapular upward rotators strength in subjects with scapular downward rotation syndrome (SDRS). Seventeen volunteer subjects with SDRS were recruited from university populations. The alignment of the scapula and clavicle was measured using radiogr...

Anterior shoulder dislocations are common in young athletes. The mechanism for the first or primary shoulder dislocation may involve a collision or a fall typically with the arm in an abducted and externally rotated position. The aim of this study was to design a physical rehabilitation program using the elastic band and resistive exercise to improve joint strength and range of motion in indivi...

The inspiratory muscles, in particular, are characteristically overloaded in COPD plus CHF, with greater elastic and resistive work of breathing. Moreover, these muscles might be functionally weakened as ventilation increases during exercise in patients with COPD [2]. It has been postulated that fatiguing contractions would stimulate diaphragmatic thinly myelinated group III and unmyelinated gr...

After pacemaker/implantable cardioverter-defibrillator (pacemaker/ICD) implantation, patients are often required to immobilize the affected arm with a sling to minimize the risk of lead displacement. We examined whether performing a resistive range-of-motion exercise protocol after pacemaker/ICD surgery would result in lead displacement and, therefore, whether sling immobilization and activity ...

PURPOSE During high-intensity, exhaustive, constant-load exercise above 85% of maximal oxygen consumption, the diaphragm of healthy subjects can fatigue. Although a decrease in trans-diaphragmatic pressure is the most objective measure of diaphragmatic fatigue, possible extra-diaphragmatic muscle fatigue would not be detected by this method. The aim of the present study was to investigate the i...
