Objectives. To determine the effect of weighted kypho-orthosis (WKO) on improving balance in women with osteoporosis. In this nonrandomized controlled clinical trial, 31 patients with osteoporosis were included. The patients were assigned to two groups: (1) control group who received 4-week home-based daily exercise program including weight bearing, back strengthening, and balance exercises and...

The hingeless plastic ankle-foot orthosis (AFO) changes stiffness largely depending on how much plastic is trimmed around the ankle. To support proper selection of the orthosis and final adjustment of the orthotic stiffness, the correlation between the posterior upright width and the resistance to dorsi- and plantar flexion movements was measured in 30 posterior-type plastic AFOs. The posterior...

In this paper, we present the mechanical design, control algorithm, and functional evaluation of a quasi-passive compliant stance control knee-ankle-foot orthosis. The orthosis implements a spring in parallel with the knee joint during the stance phase of the gait and allows free rotation during the swing phase. The design is inspired by the moment-angle analysis of the knee joint revealing tha...

Flatfoot (pes planus) is described as a reduction or absence of the medial longitudinal arch (MLA) foot, with without additional deformities foot and ankle. It very common orthopedic manifestation in infants children usually resolves by adolescence. Flat flexible painless no functional compromise so that physiologic. In some rare cases flatfoot can become painful rigid may be sign pathology suc...

OBJECTIVE To evaluate the effects of heel-opened ankle foot orthosis (HOAFO) on hemiparetic gait after stroke, especially on external foot rotation, and to compare the effects of HOAFO with conventional plastic-AFO (pAFO) and barefoot during gait. METHODS This cross-over observational study involved 15 hemiparetic patients with external rotation of the affected foot. All subjects were able to...
