Several pathologies of the foot can be solved simply by adding an orthosis under the patient’s foot. Defining the geometry and the size of such orthosis is key in optimizing its influence on the foot. For example, an orthosis with a heel lift (HL) has an increased height below the heel to force the patient to put his weight on front of the foot. An orthosis with a metatarsal bar associated with...

Paraplegic users of mechanical walking orthoses, e.g. advanced reciprocating gait orthosis (ARGO), often face high energy expenditure and extreme upper body loading during locomotion. We studied the effect of kinematical pattern on the mechanical performance of paraplegic locomotion, in search for an improved gait pattern that leads to lower muscular efforts. A three-dimensional, four segment, ...

OBJECTIVE To investigate the efficacy of tibial nerve blocking by percutaneous radiofrequency thermocoagulation and an ankle-foot orthosis on the walking ability of stroke patients with a spastic equinus or equinovarus foot. DESIGN A placebo-controlled randomized clinical trial with a 2 x 2 factorial design and with a 3-month follow-up. SETTING Outpatient clinic of a department of rehabilit...

Background. Osteoarthritis (OA) is a disease which influences the performance of the knee joint. Moreover, the force and moments applied on the joint increase in contrast to normal subjects. Various types of knee orthoses have been designed to solve the mentioned problems. However, there are other problems in terms of distal migration during walking and the alignment of the orthosis which canno...

The design of an active leg orthosis for tumble protection is proposed in this paper. The orthosis would be applied to assist elders or invalids in rebalancing while they fall unexpectedly. We observe the regain balance motion of healthy and youthful people, and find the difference to elders or invalids. First, the physical model of leg would be established, and we consider the leg motions are ...

Design of active orthosis is a challenging problem from both the dynamic simulation and control points of view. The redundancy problem of the simultaneous human-orthosis actuation is an interesting exercise to solve concerning the analytical and computational cost effectiveness. The physiological static optimization approach tries to solve the actuation sharing problem. Its objective is to quan...

Purpose of study. The purpose this study is to analyze the effect sacral-lumbar orthoses on occurrence pain in patients with low back (LBP) and effects these muscles that stabilize trunk based available literature. Methods. For study, following databases were searched: Pubmed, Scopus, ScienceDirect, Medline, others using Google Scholar search engine keywords: pain, lbp exercise, epidemiology, o...

Since 1987, 22 children with myelomeningocele have been fitted with reciprocating orthoses. The level of the spinal lesions ranged from T10 to L4 and 13 had associated spinal deformities. Twelve of the patients currently use a Reciprocating Gait Orthosis, seven use a Hip Guidance Orthosis or Parawalker, one has progressed to a Knee Ankle Foot Orthosis, one has died and one has been lost to foll...

PRIMARY OBJECTIVE The aim of this study was to assess the effect of a dynamic lycra orthosis in the management of upper limb paresis in a late stage stroke patient. RESEARCH DESIGN A single case experiment, adopting a 3-phase ABA withdrawal design (without follow-up), approximately 6-weeks per phase, intervention being delivered in the middle/B phase. METHOD AND PROCEDURES Assessment of arm...
