[Purpose] This study developed a pelvic wedge and belt and investigated their effects on the selective activation of medial and lateral hamstring muscles during knee flexion. [Subjects and Methods] Nine adults were enrolled. The participants performed exercises without and with the pelvic wedge and belt, and the electromyographic activities of the medial and lateral hamstring muscles were recor...

BACKGROUND Stair climbing is a challenging task to the elderly being the task with the first complaint in patients with mild to moderate knee osteoarthritis. Stair climbing results in around six times more compressive load transmitted through the knee joint than walking on level ground. The purpose of this study was to assess whether lateral wedge insoles would reduce medial compartment knee lo...

The effects of the lumbosacral Lumbostab orthosis on intervertebral mobility, spinal geometry, and the geometrical deformations of discs have been investigated with a three-dimensional (3-D) reconstruction technique of the lumbar spine. Positions studied are neutral standing, maximal flexion, extension, left lateral bending, and left axial rotation. Results from this preliminary study indicate ...

Background Patients with knee OA usually present with major involvement in the medial compartment characterized by joint inflammation, loss of cartilage and joint space and experience increased loads across this compartment. These contribute to pain, changes in muscle control and may interfere with balance and postural control [1,2]. Laterally wedged insoles or footwear components have been use...

Background Spinal deviations usually refer to abnormal lateral or sagittal curvature that could be the cause or effect of some spinal diseases. The conventional orthotic intervention is to apply passive forces to a patient's body with an orthosis for supporting and controlling the trunk alignments. However, once the orthosis is removed, such functions cannot be maintained. Therefore, an active ...

introduction: knee joint osteoarthritis is one of the most prevalent musculoskeletal problems in adult population, which cause pain and functional limitations. involvement of medial compartment is almost 10 times more common than lateral compartment, which results in varus deformity among patients with medial compartment osteoarthritis of knee joint. main objectives in the treatment of knee joi...

A dental orthosis, designed to increase the size of the upper airway by advancing the mandible, was used in 68 patients to treat snoring and varying degrees of obstructive sleep apnea. The orthosis increased the posterior airway space, as assessed by lateral cephalograms. Seven months (range 2 to 25) after beginning use, 75 percent of patients were using the orthosis regularly. Snoring, by repo...

measurement of the loads exerted on the limb is a fundamental part of designing of an assistive device, which has been done by using strain gauges or a transducer. although calculation of loads applied on an orthosis coefficients achieved from calibration is a standard way, most of researchers determined the loads based on available equations. therefore, the aim of this research is finding the ...

Material and methods TCFO is foot orthosis which combines inverted rigid foot orthosis(RFO) with broad upright portion that covers and protects the talonavicular joint, rising well above the navicular. Fourty children were participated in this study who had been diagnosed as flexible pes planus, and had more than two consecutive radiologic studies. The anteroposterior talocalcaneal angles (APTC...
