Post-traumatic elbow rotational stiffness [PDF]
Shoulder & Elbow, 2014 Background The elbow is an important but complex structure, with movement in both the sagittal plane in flexion and extension, as well as the rotational plane in forearm supination and pronation. Trauma is a common cause of elbow stiffness, which significantly hampers daily function.

Shoulder stiffness and rotator cuff repair [PDF]
British Medical Bulletin, 2012 Shoulder stiffness is a frequent complication of surgical repair of rotator cuff tears. Post-operative stiffness negatively affects surgical outcomes leading to a substantial comorbidity and to the failure of surgical treatment. Also, a stiff shoulder could commonly be concomitant with an rotator cuff tear (RCT).We performed a comprehensive search of ...

Infinitely stiff composite via a rotation-stabilized negative-stiffness phase [PDF]
Applied Physics Letters, 2011 We show that an elastic composite material having a component with sufficiently negative stiffness to produce positive-infinite composite stiffness can be stabilized by the gyroscopic forces produced by composite rotation.

Rotator Interval Lesion: Instability & Stiffness [PDF]
The Journal of the Korean Shoulder and Elbow Society, 2005 Rotator interval should be as loose as possible, though not so loose as to break the shoulder mechanism. This region is a source of significant shoulder pathology resulting in patient discomfort and dysfunction. The clinical features fall into two categories.

Analysis of Rotational Stiffness of the Timber Frame Connection [PDF]
Sustainability, 2020 Initially, timber was considered only as an easily accessible and processable material in nature; however, its excellent properties have since become better understood. During the discovery of new building materials and thanks to new technological development processes, industrial processing technologies and gradually drastically decreasing forest ...

A novel energy-efficient rotational variable stiffness actuator
2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011 This paper presents the working principle, the design and realization of a novel rotational variable stiffness actuator, whose stiffness can be varied independently of its output angular position. This actuator is energy-efficient, meaning that the stiffness of the actuator can be varied by keeping constant the internal stored energy of the actuator ...

Passive Stiffness of Coupled Wrist and Forearm Rotations
Annals of Biomedical Engineering, 2014 Coordinated movement requires that the neuromuscular system account and compensate for movement dynamics. One particularly complex aspect of movement dynamics is the interaction that occurs between degrees of freedom (DOF), which may be caused by inertia, damping, and/or stiffness. During wrist rotations, the two DOF of the wrist (flexion-extension and

Rotational and peak torque stiffness of rugby shoes
The Foot, 2014 Sports people always strive to avoid injury. Sports shoe designs in many sports have been shown to affect traction and injury rates. The aim of this study is to demonstrate the differing stiffness and torque in rugby boots that are designed for the same effect.Five different types of rugby shoes commonly worn by scrum forwards were laboratory tested ...

Stiffness and arthroscopic rotator cuff repair: a literature review
Annals of Joint, 2023 Tendon retear is the most common complication following rotator cuff repair surgery. Understanding the factors that are associated with greater risks of retear is important so surgeons can provide accurate prognostic information to patients. Advanced age and larger tear size have been shown to be associated with greater risk of retear at 6 months using
