Quantitative evaluation of the hemiparesis status for a poststroke patient is still challenging. This study aims to measure and investigate the dynamic muscle behavior in poststroke hemiparetic gait using ultrasonography. Twelve hemiparetic patients walked on a treadmill, and EMG, joint angle, and ultrasonography were simultaneously recorded for the gastrocnemius medialis muscle. Pennation angl...

In this paper, we describe a new vector similarity measure associated with a convex cost function. Given two vectors, we determine the surface normals of the convex function at the vectors. The angle between the two surface normals is the similarity measure. Convex cost function can be the negative entropy function, total variation (TV) function and filtered variation function. The convex cost ...

BACKGROUND To perform total knee arthroplasty, some surgeons prefer to use a fixed valgus angle, for example 5° or 6°, for the distal femoral cut with every patient. This angle may be appropriate for some patients, but may not be for all. OBJECTIVE To determine the proper angle of the distal femoral cut during total knee arthroplasty (TKA) in Thai patients with osteoarthritis of the knee. M...

OBJECTIVE To determine the extent to which select lower extremity alignment characteristics of the pelvis, hip, knee, and foot are related to the Q angle. DESIGN Descriptive cohort study design. SETTING Applied Neuromechanics Research Laboratory. PARTICIPANTS Two hundred eighteen participants (102 males, 116 females). ASSESSMENT OF RISK FACTORS Eight clinical measures of static alignmen...

Purpose: The forward shoulder (FS) is one of the most common deformities accounted for 60% of shoulder abnormalities.This study aimed to investigate the effects of a 6-weekstrength training, stretch training andcomprehensive training in patients with forward shoulder abnormalities. Methods:This quasi-experimental study design Pre-posttest with control group. Forty females students with exc...

Cobb angle, which is a measure of spinal curvature, is the standard method for quantifying the magnitude of Scoliosis, related to spinal deformity in orthopedics. Determining the Cobb angle through manual process is subject to human errors. In this work, we propose a methodology to measure the magnitude of Cobb angle, which appreciably reduces the variability related to its measurement, compare...

OBJECTIVE To test the reliability and validity of shoulder joint angle measurements from the Microsoft Kinect™ for virtual rehabilitation. DESIGN Test-retest reliability and concurrent validity, feasibility study. SETTING Motion analysis laboratory. PARTICIPANTS A convenience sample of 10 healthy adults. METHODS Shoulder joint angle was assessed in four static poses, two trials for each...

In this work an innovative unsupervised change detection technique for multispectral and hyperspectral images is proposed. It consists in the comparison between two co-registered and radiometrically correct multispectral images, carried out by comparing pixels’ spectral signatures. Supposing a change is occurred, we can state that the spectral vector associated to a pixel in the “changed image”...

BACKGROUND One of the reasons women with macromastia chose to undergo a breast reduction is to relieve their complaints of back, neck, and shoulder pain. We hypothesized that changes in posture after surgery may be the reason for the pain relief and that patient posture may correlate with symptomatic macromastia and may serve as an objective measure for complaints. The purpose of our study was ...
