METHODS A questionnaire was developed including personal factors such as age, practice of physical and sports activities, general health habits, occupation-related issues, and factors associated with low back pain. The body mass index (ratio o...

We examined the effects of load carriage position on the energy cost of walking defined as the ratio of the 2-min steady-state oxygen consumption to the speed and economical speed. Fourteen healthy men walked on a treadmill at various speeds without and with load on the lower and upper back, which corresponded to 15% of their body mass. The energy cost of walking significantly decreased during ...

Pregnancy- and lactation-associated osteoporosis (PLO) is a rare form of osteoporosis. It results in severe low back pain in the last trimester of pregnancy and in the postpartum period, decreases in height, and fragility fractures, particularly in the vertebra. The current case report presents a 32-year-old patient who presented with back and low back pain that began in the last trimester of t...

introduction: low back pain is the most common musculoskeletal complication. although there are many ways to treat low back pain, achieving a concise, simple, and compact method is required in today's industrial societies. the purpose of this study was to evaluate the effect of six weeks selected core stabilization exercises on pain and functional disability in patients with nonspecific chronic...

the ability to optimize muscular power output is considered as a basis for successful performance in the most sports. the aim of this study was to investigate changes in dynamic exercise performance following a sequence of preconditioning isometric muscle actions. twelve nonathlete, active female volunteers (age: 16±1 yr, height: 162±6.34 cm, weight: 60±9.21 kg) participated in the present stud...

Vibration transmission is essential in the design of comfortable vehicle seats but knowledge lacking on 3D trunk and head motion role seat back posture. We hypothesized that reduced when participants’ upper unsupported, as this stimulates active postural control. developed an experimental methodology to evaluate vibration from compliant human body. Wide-band (0.1–12 Hz) stimuli were applied for...
