Since a significantly greater percentage of body weight is supported by the non-paretic limb following stroke, a greater amount of fatigue may be present during daily activities. This may affect the ability of these individuals to maintain a stable upright posture. The presence of falls following a stroke has been attributed in part to this asymmetrical stance post-stroke. Therefore the purpose of this study was to assess the effect of quadriceps muscle fatigue on bi-pedal posture in individuals who had a stroke and an age-matched control group. Although individuals after stroke displayed greater postural sway under the paretic limb than the non-paretic limb or control subjects, results of this study show that sustaining an isometric knee extension of the non-paretic limb induces changes in postural control for individuals after stroke, but that these changes do not markedly differ from those of healthy age-matched controls.

ABSTRACT Postural deformities are a commonly encountered problem among children. Most of the aches and pains of adults are the result, not of injuries, but of the long-term effects of distortions in posture or alignment that have their origins in childhood or adolescence. Television, video entertainment, motorized transportation, fast food and lack of regular physical activity contribute to the poor physical condition of children. Childhood obesity has increased dramatically in the past decade. Countries in economic transition from underdeveloped to developed, such as South Africa, are particularly affected and have an increasing prevalence of obesity across all economic levels and age groups. In a developing country like South Africa, where overweight/obesity co-exists with undernutrition, there is an urgent need to prevent unhealthy trends in diet and physical activity. School screening is mandatory in schools in 26 states of the United States (US) for children between 10 and 16 years of age. Previous studies conducted in the US found that 160 out of 1000 people suffer from scoliosis (Boachie-Adjei & Lonner, 1996). This means that scoliosis is as prevalent as hypertension or diabetes mellitus. Identification of postural deformities at an early stage makes early treatment possible, which may, in future, prevent serious postural abnormalities. The aim of this review article is to define the concept of good posture, analyze normal postural development and postural deformities, and discuss some of the developmental factors affecting posture.

The purpose of this Master's project was to investigate the effects of a l2-week Pilates training program on neck-shoulder posture and motion, core strength and neck-shoulder kinematics and muscles activity associated with a shoulder flexion task performed under six different conditions. After the training, scapula anterior tilt and upper and lower thoracic extension were reduced and there was increased activity of the rectus abdominis, serratus anterior and rhomboid muscles during the shoulder flexion task; passive shoulder range of motion increased in flexion and internal rotation; static thoracic kyphosis was smaller and abdominal strength was greater. Theses results suggest that Pilates is effective in improving core strength, thoracic static and dynamic posture, and shoulder flexibility as well as in stabilizing core posture as limb movements are performed. Our results support the use of the Pilates method in the rehabilitation, and possibly in the prevention, of neck-shoulder disorders.

Since a significantly greater percentage of body weight is supported by the non-paretic limb following stroke, a greater amount of fatigue may be present during daily activities. This may affect the ability of these individuals to maintain a stable upright posture. The presence of falls following a stroke has been attributed in part to this asymmetrical stance post-stroke. Therefore the purpose of this study was to assess the effect of quadriceps muscle fatigue on bi-pedal posture in individuals who had a stroke and an age-matched control group. Although individuals after stroke displayed greater postural sway under the paretic limb than the non-paretic limb or control subjects, results of this study show that sustaining an isometric knee extension of the non-paretic limb induces changes in postural control for individuals after stroke, but that these changes do not markedly differ from those of healthy age-matched controls.
