RISQuantifying Dysfunction of the Lumbar Multifidus Muscle After Radiofrequency Neurotomy and Fusion Surgery: A Preliminary Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The multifidus is an important muscle for the active stabilization of the spine. Unfortunately, clinical procedures such as posterior lumbar fusion (PLF) and radio frequency neurotomy (RFN) cause injury to these muscles ...
Quantifying the Fascicular Changes in Recovered Achilles Tendon Patients Using Diffusion Magnetic Resonance Imaging and Tractography
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Regardless of the way of treatment, persistent deficits in calf muscles in recovered patients from Achilles tendon rupture (ATR) exist long-term postinjury. Studies on calf muscle changes mostly highlight morphological ...
Change in Shear Modulus of Healthy Lower Leg Muscles After Treadmill Running: Toward a Noninvasive Diagnosis of Chronic Exertional Compartment Syndrome
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Chronic exertional compartment syndrome (CECS) is an exercise-induced condition, in which high pressure develops in one or several lower leg compartments, resulting in pain, numbness, and temporary muscle paresis. Diagnosis ...
Finite Element Simulation of Proportional, Integral, and Derivative-Controlled Bipolar Radiofrequency Ablation of Porcine Spinal Muscle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Radio frequency ablation (RFA) of the medial branch nerve is a widely used therapeutic intervention for back pain originating from the facet joint. However, multifidus denervation is a well-known adverse effect of this RFA ...
Biaxial Tension of Fibrous Tissue: Using Finite Element Methods to Address Experimental Challenges Arising From Boundary Conditions and Anisotropy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Planar biaxial tension remains a critical loading modality for fibrous soft tissue and is widely used to characterize tissue mechanical response, evaluate treatments, develop constitutive formulas, and obtain material ...
Evaluating Changes in Shear Modulus of Elbow Ulnar Collateral Ligament in Overhead Throwing Athletes Over the Course of a Competitive Season
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The anterior band of the ulnar collateral ligament (UCL) is commonly subjected to repetitive stress in overhead-throwing athletes, causing high subfailure strain and change in mechanical properties of the ligament. ...
Ultrasound Shear Wave Elastography of the Elbow Ulnar Collateral Ligament: Reliability Test and a Preliminary Case Study in a Baseball Pitcher
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Overhead throwing athletes are at high risk of the elbow ulnar collateral ligament (UCL) injury, and there is a need for clinical tools to objectively diagnose severity of injury and monitor recovery. Mechanical properties ...
Changes in Shear Modulus of the Lumbar Multifidus Muscle During Different Body Positions
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Multifidus function is important for active stabilization of the spine, but it can be compromised in patients with chronic low back pain and other spine pathologies. Force production and strength of back muscles are often ...
