Rotator Interval and Stiffness
2015The rotator interval is a triangular space located between the subscapularis and supraspinatus tendons in the anterosuperior region of the shoulder. Within its borders lie the superior glenohumeral and coracohumeral ligaments, the long head of biceps tendon, and capsule.

Prevention of Shoulder Stiffness after Rotator Cuff Repair
Clinical Orthopaedics & Related Research, 2005Predisposing factors for shoulder stiffness after rotator cuff repair have yet to be determined. The potential for recovery of range of motion and amelioration of pain in patients with this complication also remains unclear. Accordingly, data collected prospectively for 209 patients with a primary rotator cuff repair were retrospectively reviewed.

Clinical Biomechanics, 2022
Qualitative clinical assessments of spinal stiffness have been demonstrated to show moderate correlations with one-another. We hypothesized that these correlations would improve in an in vitro model of the functional spinal unit. If the stiffness of spinal units are different across loading regimes (e.g.

Quasi‐All‐Directional Negative Stiffness Metamaterials Based on Negative Rotation Stiffness Elements
physica status solidi (b), 2020Most negative stiffness metamaterials exhibit negative stiffness effects in only one direction. Herein, based on the theory of anisotropy, the concept of “negative stiffness” is redefined. A method to determine whether a material has all‐directional negative stiffness is proposed.

Rotational stiffness of shallow footings
Computers and Geotechnics, 1992Abstract The details of footing design, the soil stiffness and the soil resistance all affect the rotation characteristics of column bases of structural frames. This can have a considerable influence on structural economics (strength design), structural deflections (serviceability design) and on structural stability.

Axial stiffness of a rotating trunnion joint
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2014A trunnion joint is modeled as a circular plate with two types of outer boundary conditions. One is clamped supported and the other is simply supported. Symmetrical bending deflection is produced when an external force acts on the inner side of the circular plate.

Design principle of wing rotational hinge stiffness
2015 IEEE International Conference on Robotics and Automation (ICRA), 2015A design principle for selecting the stiffness of a wing rotational flexure hinge on bio-inspired flapping wing robots is presented. In this work, a systematic approach of selecting rotational stiffness values such that the primary mode of resonance occurs at harmonics of the wing stroke frequency is proposed.

Rotational Stiffness at Ridges of Timber Folded-plate Structures
IABSE Reports, 2015<p>Folded plate structures propose an efficient design employing thin Laminated Veneer Lumber panels. Inspired by the Japanese furniture joining technique, the Multiple Tab-and-Slot Joint was developed as a solution for multi-assembly of timber panels with non-parallel edges, requiring no adhesive or metal joints.

Traumatic Rotator Cuff Tears with Shoulder Stiffness
2020Traumatic rotator cuff tears and stiffness have opposite first line treatment options. While pure traumatic rotator cuff tears may benefit from early surgical treatment followed by a short but important immobilization period, stiffness patients benefit from early and continuous mobilization and surgery is reserved for those cases that don’t recover ...

The factors affecting stiffness occurring with rotator cuff tear
Journal of Shoulder and Elbow Surgery, 2012Stiffness after a rotator cuff tear is common, and it affects postoperative prognosis. This study aims to define the factors affecting stiffness that accompanies rotator cuff tear.From June 2002 to May 2009 (84 months), 143 patients underwent arthroscopic rotator cuff repair. Of these, 119 were enrolled as subjects in this study.
