The purpose of this study is to investigate healthy people’s and patients’ lower extremity muscle activities during robotic gait using kinesiology analysis. Initially, signals were taken from 6 paraplegic patients such as spinal cord injury (SCI) stroke patients, 2 hemiplegic 4 persons. Then, analyzed by signal processing techniques filtering, rectifying, Root Mean Square (RMS) also calculating...

Sheard, PW and Paine, TJ. Optimal contraction intensity during proprioceptive neuromuscular facilitation for maximal increase of range of motion. J Strength Cond Res 24(X): 000–000, 2009—An informal review of literature on the use of postisometric relaxation (PIR) type proprioceptive neuromuscular facilitation (PNF) indicates that the force of contraction requested from the athlete ranges from ...

of Thesis entitled Musculotendon Modeling of the Elbow Joint for Unimpaired Subjects and Persons after Stroke using Noninvasive and In Vivo Information submitted by Li Le for the Degree of Doctor of Philosophy at The Hong Kong Polytechnic University in March 2007 Neuromusculoskeletal modeling provides insights into the muscular system which are not always obtained through experiment or observat...

Balanced forces around the shoulder are important for normal function; however, rehabilitation guidelines are not well defined because the muscle contributions and optimal exercise technique to recruit them are poorly understood. This study aimed to determine (1) the conditions of resisted isometric external rotation that optimized the contribution of infraspinatus and (2) the load of external ...

Ten young men sustained an isometric contraction of the knee extensor muscles at 20% of the maximum voluntary contraction (MVC) torque on three separate occasions in a seated posture. Subjects performed an isometric knee extension contraction on a fourth occasion in a supine posture. The time to task failure for the seated posture was similar across sessions (291 +/- 84 s; P > 0.05), and the MV...

BACKGROUND Frequent or chronic tension-type headache in children is a prevalent and debilitating condition for the child, often leading to medication overuse. To explore the relationship between physical factors and tension-type headache in children, the quality of repeated measures was examined. The aim of the present study was to determine the test-retest repeatability of parameters determini...

The objectives of this study were to probe the contribution of spinal neuron persistent sodium conductances to reflex hyperexcitability in human chronic spinal cord injury. The intrinsic excitability of spinal neurons provides a novel target for medical intervention. Studies in animal models have shown that persistent inward currents, such as persistent sodium currents, profoundly influence neu...
