Stiffness control in posterior-type plastic ankle-foot orthoses: effect of ankle trimline. Part 1: A device for measuring ankle moment.
نویسندگان
چکیده
A device was developed to measure the dorsi- and plantar flexion moment of plastic ankle-foot orthoses when deflected. It is operated by manually controlling a lever which is used to apply a nearly static force. Various orthoses can be classified according to the characteristics of the correcting force measured by this device. Simplicity and high reproducibility are the major advantages. However, to obtain measurements approximating the characteristics of orthoses under wearing conditions its use is restricted to orthoses made of low-viscosity materials.

Stiffness control in posterior-type plastic ankle-foot orthoses: effect of ankle trimline. Part 2: Orthosis characteristics and orthosis/patient matching.
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...
متن کاملInstantaneous centers of rotation in dorsi/plantar flexion movements of posterior-type plastic ankle-foot orthoses.
Hingeless plastic ankle-foot orthoses (PAFOs) achieve ankle motion by flexing about the ankle joint. Instantaneous centers of rotation (ICRs) in dorsi- and plantarflexion movements, used as a measure of PAFO axes of movement, were measured to evaluate their fit to ankle motion. Thirty different PAFOs were fabricated and their stiffness modified in three stages. They were dorsi- and plantarflexe...
متن کاملEffects of the Custom Mold with a Raised Ridge around the Perimeter Foot Orthoses on Dynamic Postural Control in Chronic Ankle Instability
Background and Objectives: Among the foot orthoses prescribed to improve postural control in chronic ankle instability, foot orthoses designed to affect both types of mechanical and functional instability have a limited research background. In the present study, a type of foot orthosis named the custom mold with a raised ridge around the perimeter was designed, and manufactured, and its effect ...
متن کاملEfficacy of Different Types of Foot Orthoses on Postural Control in Subjects With Lateral Ankle Sprain: A Systematic Review
Background and Objectives: Lateral ankle sprain is one of the most common injuries to the musculoskeletal system, especially among active people. This injury causes complex complications, such as recurrent sprain because of reduced postural control. Foot orthoses are among the interventions used to improve postural control in this population. This review aims to investigate foot orthoses to imp...
متن کاملComparing the Effects of Flexible and Rigid Ankle-Foot Orthoses on Balance/Walking Performance in Individuals With Multiple Sclerosis
Background: Ankle-Foot orthoses are used to minimize the impact of weakness in ankle dorsiflexion muscles. The study on different orthotic types defines the optimal design, which effectively improves the users’ mobility. This study investigated the potential benefits and risks of a Dictus-band (flexible orthotic), compared with a thermoplastic (fixed) ankle-foot orthosis on the mobility of indi...
