Strength training is commonly performed at two different knee flexion amplitudes: partial (to 90 degrees) or total (to 140 degrees). During these amplitudes, both the pelvis and the tibia are moved to ensure control of the center of gravity and displacement of the external overload. Forward or backward movement of the pelvic tilt may indirectly influence the internal load on the spine. Objectiv...

The integration of prostheses or wearable robotics into the body schema of their users is a fundamental requirement for the acceptance and control of such artificial devices. Duration and progress of integration are primarily influenced by visual, tactile, and proprioceptive perception. This paper describes the IntBot, a robot for the assessment of lower limb body schema integration during post...

Orthostatic (postural) hypotension (OH) is a common, yet under diagnosed disorder. It may contribute to disability and even death. It can be the initial sign, and lead to incapacitating symptoms in primary and secondary autonomic disorders. These range from visual disturbances and dizziness to loss of consciousness (syncope) after postural change. Evidence based guidelines for the diagnostic wo...

We report an experiment on three house allocation mechanisms under complete information: random serial dictatorship with squatting rights, and two variants of the top trading cycles mechanism. Results show that the latter two are significantly more efficient than the former. D 2004 Elsevier B.V. All rights reserved.

Objective To provide the off -loading knee brace was designed relief for the pain associated with osteoarthritis by reduce loads on the degenerative compartment of the knee. Th is study examined the eff ects of the off -loading knee brace on activation of femoral muscles during squatting, slow and fast walking exercise in healthy young individuals. Method Ten healthy male subjects without a his...

Squatting is a basic movement of bipedal robots, which essential in robotic actions like jumping or picking up objects. Due to the intrinsic complex dynamics perfect squatting motion requires high-performance planning and control algorithms. The standard academic solution combines model predictive (MPC) with whole-body (WBC), usually computationally expensive difficult implement on practical ro...

Abstract Background We aimed to determine whether different urination positions had significant impact on the parameters of uroflowmetry performed by healthy individuals and children with voiding dysfunction. Methods The study was conducted a prospective comparative design. Children between 5 15 years age who met inclusion–exclusion criteria were enrolled. in divided into two groups. Participan...

Introduction The frontal plane projection angle (FPPA) is a measure of the degree of dynamic knee valgus during functional tasks such as the single leg squat. An increased FPPA is associated with patellofemoral pain and is indicative of knee valgus during other tasks such as running. Therefore, it is important to determine factors that can contribute to FPPA in order to develop treatment strate...

In recent years a great deal of research efforts in ship hydromechanics have been devoted to practical navigation problems in moving larger ships safely into existing harbors and inland waterways. An area of particular concern is the prediction of ship squat in shallow or restricted waters at different speeds. Squat may cause grounding of the ship which result in severe damage to the ship, and ...

As quoting in the philosophy of free dance: «Understanding the directions for a Free Dance performer stems mainly from the qualities and energy of the movement rather from spatial criteria», we advocate that dance movement is not only to perform a desired motion but also to feel and to transmit “sensation (expression)” by body and energy. Dynamic models are particularly adequate for this object...
