Static Progressive Splinting for Posttraumatic Elbow Stiffness

Journal of Orthopaedic Trauma, 2006
To determine the value of static progressive splinting in helping patients with posttraumatic elbow stiffness regain functional motion and avoid operative treatment for stiffness.Retrospective case series.Level I Trauma Center.Over a 3-year period, 29 consecutive patients with elbow stiffness after trauma (flexion contracture greater than 30 degrees or

Static progressive stretch for the treatment of knee stiffness

The Knee, 2008
Persistent knee stiffness is common after knee arthroplasties, cruciate ligament repairs, and trauma. Static progressive stretch protocols have shown success in treating contractures of the elbow, ankle, and knee in case reports and small case series. This study evaluated static progressive stretch as a treatment method for patients who had refractory ...

Skeletal muscle stiffness in static and dynamic contractions

Journal of Biomechanics, 1994
Series elastic stiffness of rat gastrocnemius medialis muscle was determined by means of sinusoidal movements (180 Hz, 0.25% of muscle length) for various contraction conditions. The effects of muscle length, activation level, velocity, prestretch, and temperature on the force-stiffness relationship were investigated.

Stiffness and Strength Governing the Static Liquefaction of Tailings

Journal of Geotechnical and Geoenvironmental Engineering, 2013
AbstractIn this study, the behavior of gold tailings is evaluated by a series of drained and undrained triaxial tests carried out in compression and extension and sheared under monotonic loading, allowing the critical state line (CSL) to be established.

Calculation of Static Stiffness of Hyperelastic Coating

Applied Mechanics and Materials, 2013
The fundamental theory about the constitutive relationship of hyperelastic model has been introduced and the model of super-elastic coating has been simulated in this paper. The static stiffness of different coating thickness has been calculated considering the hyperelasticy and viscoelasticity.

New static and dynamic stiffness testers

Journal of Applied Polymer Science, 1974
AbstractInstruments have been developed for the testing of stiffness of polymers in various gaseous environmental “atmospheres” over a large range of temperatures. They are based on the cantilever principle, where a small strip of a specimen is deflected statically or periodically.

Optimal Stiffness Distribution: Static Loading

2014
This chapter is concerned with the first step in passive motion control, establishing a distribution of structural stiffness that produces the desired displacement profile. The stiffness distribution for static loading applied to a set of structures consisting of continuous cantilever beams, building-type structures modeled as equivalent discontinuous ...

Evaluation of Static Progressive Stretch for the Treatment of Wrist Stiffness

The Journal of Hand Surgery, 2008
Decreased wrist flexion and/or extension after trauma or surgery can be a challenging problem. Physical therapy, orthoses, and additional surgical interventions may not restore the desired range of motion or functionality. The purpose of this study was to assess the total arc of motion and the satisfaction scores of patients who had wrist stiffness and

Identification of the Critical Stiffnesses of Motorcycles in Static and Dynamic Conditions

Volume 3: 18th International Conference on Advanced Vehicle Technologies; 13th International Conference on Design Education; 9th Frontiers in Biomedical Devices, 2016
Stiffness of structural elements has a significant effect on the dynamics of single-track vehicles, because it influences the stability of the typical modes of this class of vehicles (weave and wobble). Up to date no specific method for measuring the critical stiffnesses of front fork, chassis and swingarm is universally recognized. This measurement is

Static Stiffness of Unbounded Soil by Finite-Element Method

Journal of Geotechnical Engineering, 1996
To calculate the static-stiffness matrix of the unbounded soil for use in a time-domain analysis of soil-structure interaction, the consistent infinitesimal finite-element cell method is developed. Its derivation is based on the finite-element formulation and on similarity.
