Nonlinear analysis techniques are necessary to understand the complexity of the EMG. The purpose of the present study was to determine the fractal dimension of surface EMG obtained from the biceps brachii of normal subjects during isokinetic flexion-extension of the arm. The measurements were obtained with different loading conditions on the arm and for(More)
Growing importance of telesurgery has led to the need for the development of synergistic control of anthropomorphic teleoperators. Synergistic systems can be developed using direct biological control. The purpose of this study was to develop techniques for direct biocontrol of anthropomorphic teleoperators using surface electromyogram (EMG). A computer(More)
Dysphagia is a disorder of the swallowing mechanism and presents a major problem in the rehabilitation of stroke patients and head injured patients. The authors have identified several biomechanical parameters that characterize the oral musculature and have developed techniques to quantify these parameters in normal and dysphagic patients. These parameters(More)
Interstitial fluid pressure (IFP) distribution generated as a result of externally applied pressure (EAP) may play an important role in the etiology of decubitus ulcers. In the forelimbs of 10 thiopental sodium-anesthetized Yorkshire pigs, weighing 16-20 kg, we placed wick catheters 2-5 mm below the skin. After equilibration, we applied a pediatric cuff and(More)
Proper understanding of the mechanisms of fluid absorption and flow through the terminal lymphatics is essential for the control of several pathological conditions such as edema, bedsores and cancer. A mathematical model of the terminal lymphatics was developed using the principles of mechanics. Computer simulation results substantiate the hypothesis that(More)
An asymmetric 3-dimensional finite element model (FEM) of the ankle-foot orthosis (AFO) together with the ankle-foot complex was developed using the computer aided design (CAD) program PATRAN. Static analysis of normal and pathological motions of the ankle-foot complex such as the "drop-foot" problem were conducted using the FEM program ADINA. A total of(More)
The swallowing process is divided into three distinct phases: (1) an oral phase involving the coordinated action of the muscles of the lips, tongue, and cheeks; (2) a pharyngeal phase involving pharynx and larynx; and (3) an esophageal phase involving transit of the bolus from the pharynx into the stomach. A description is given of quantitative measurement(More)
Lymphocytes which become sensitised at the periphery travel to the regional lymph nodes where they initiate an immunological response by increasing the production of immuno-competent lymphocytes. These lymphocytes migrate into the tissues via the blood stream and bring about the destruction of target cells. These notions, in the present analysis, are(More)
Swallowing disorder (dysphagia) presents a major problem in the rehabilitation of stroke and head injured patients. In the present investigation, a new technique is developed for noninvasive assessment of the pharyngeal phase of the swallowing mechanism. Acceleration was measured with two ultra-miniature accelerometers placed on the skin over the throat.(More)
