Muscle wrap can refer to two different things. Firstly, it can refer specifically to arm wrap and leg wrap, which are terms used by SolidCore to describe exercises that focus on the muscles that help us move laterally. Secondly, muscle wrap can refer to muscle wrapping in the context of musculoskeletal models, which is the process of simulating muscle paths in these models to better predict forces and facilitate real-time clinical applications such as rehabilitation.

Muscle wrapping is used in the design of spinal implants and lumbar orthoses
Muscle wrapping is a technique used in the design of spinal implants and lumbar orthoses, which are external aids used to correct and support the spine. The spine is a complex anatomical structure that plays a key role in human function. While spinal conditions may not always be treated with orthotics alone, orthoses can be used to correct issues such as fractures, intravertebral disc complications, spondylolisthesis, lordosis, kyphosis, scoliosis, soft tissue injuries, sprains, and muscle injuries.
The muscle-driven spine model is used for predictive simulations in the design of these spinal implants and orthoses. This model takes into account factors such as local and global musculature, body weight, intra-abdominal pressure, and forces from abdominal soft tissue support. By simulating muscle paths, the model can better predict forces and facilitate real-time clinical applications like rehabilitation with real-time feedback.
The muscle-driven spine model is also useful for evaluating the internal dynamics of the spine and the influence of orthoses on the biomechanical responses of the spine model. This is achieved by modelling a muscle path as a massless, frictionless elastic strand that uses artificial forces to wrap tightly around intervening obstacles. The model has been implemented in the open-source simulation system ArtiSynth, which helps address the problem of muscle wrapping around bones and other structures.
Overall, this muscle-driven spine model is a valuable tool for the virtual product design of medical devices, ensuring safety and efficacy for patients. It can also support manufacturers in proving their compliance with regulatory requirements, such as the Medical Devices Regulation (MDR, EU-V 745/2017) in the European Union.

Muscles wrap over multiple anatomical features, moving along curved paths
Skeletal muscles usually wrap over multiple anatomical features, and their mass moves along curved paths during human locomotion. The mass distribution of muscles plays a significant role in the force transmission of muscle wrapping. Existing musculoskeletal models often simplify the mass of muscles by lumping them with nearby body segments, neglecting the influence of mass flow, which can lead to notable errors.
To address this, a mass-variable multibody formulation has been proposed to simultaneously analyse muscle wrapping and mass flow effects. This involves the development of a novel cable element within the muscle-tendon unit, integrating the mass flow characteristic with a typical Hill-type constitutive relationship. The formulation provides a more accurate way to predict and understand the dynamics of musculoskeletal systems.
Muscle wrapping can be modelled as a massless, frictionless elastic strand that uses artificial forces to wrap tightly around intervening structures. This method has been applied to simulate muscle paths around bone geometries, improving predictions of forces and facilitating real-time clinical applications such as rehabilitation with immediate feedback.
Additionally, the heat method has been used for muscle wrapping on arbitrary meshes, and algorithms have been developed for exact multi-object muscle wrapping, such as the deltoid muscle wrapping around the humerus. These advancements in muscle wrapping modelling offer new possibilities for patient-specific musculoskeletal models, enhancing our understanding of the complex dynamics of the human body in motion.

Muscle wrapping is used in surgical planning and clinical assessment of gait and movement
Muscle wrapping is a technique used in musculoskeletal modelling, which plays a crucial role in surgical planning and clinical assessment of gait and movement. Gait analysis involves the quantitative evaluation of parameters such as joint kinematics, spatiotemporal metrics, external forces, and muscle activation patterns and forces.
Musculoskeletal models provide a non-invasive tool for predicting internal joint and muscle forces, which is essential for clinical decision-making. For example, in the case of femoro-acetabular impingement (FAI), gait analysis helps evaluate muscle forces and joint loading patterns, revealing changes in walking mechanics and muscle imbalances. This information is then used to develop personalized rehabilitation programs and surgical interventions.
The muscle path wrapping technique models a muscle path as a massless, frictionless elastic strand that uses artificial forces to wrap tightly around intervening obstacles. This method has been proven to be highly accurate and efficient, with mean relative errors of 0.002 or better when compared to simple cases with exact solutions.
By simulating muscle paths in musculoskeletal models, clinicians can better predict forces and facilitate real-time clinical applications. This includes rehabilitation with real-time feedback, allowing for a more precise understanding of muscle coordination and synchronization during movement.

Arm wrap and leg wrap are terms used by SolidCore to refer to upper and lateral body exercises
"Arm wrap" and "leg wrap" are terms used exclusively by SolidCore to refer to exercises targeting specific muscle groups in the upper and lower body, respectively. These terms are not anatomical but are part of the unique terminology used in SolidCore classes.
An "arm wrap" focuses on the upper body, specifically the chest or back, paired with the biceps and triceps. This allows for working on multiple muscle groups in a single 50-minute session.
A "leg wrap" targets the leg muscles that enable lateral movement, including the inner thighs, outer thighs, and outer glutes. By focusing on these muscles, which are often underutilized in daily human movement patterns, "leg wrap" exercises aim to improve balance and reduce the risk of injuries.
The SolidCore program differs from traditional Pilates or core Pilates classes due to its emphasis on specific muscle groups, such as during "leg wrap" and "arm wrap" days, and its rotating muscle focus. This terminology is part of the unique language used in SolidCore, helping to create a sense of community among its practitioners and instructors.

Muscle wrapping on arbitrary surfaces opens up new possibilities for patient-specific musculoskeletal models
Muscle wrapping, or muscle path wrapping, is a technique used in musculoskeletal modelling. It involves simulating the interaction between muscles and skeletal structures, particularly as muscles wrap around hard tissue such as bone. This process is important for understanding the biomechanics of patient-specific models.
Traditional muscle wrapping methods use simple geometric shapes for wrapping surfaces. However, a new method has been proposed that allows for faster and more robust simulation of muscle paths interacting with arbitrary mesh-based surfaces. In this method, a muscle path is modelled as a massless, frictionless elastic strand that uses artificial forces to wrap tightly around intervening obstacles. The contact with arbitrary surfaces is computed using a distance grid, which is interpolated quadratically to provide smoother results.
This novel method has been evaluated for accuracy and speed, demonstrating promising outcomes. It has been implemented in the open-source simulation system ArtiSynth and can be applied to various bone-shaped obstacles.
The significance of muscle wrapping on arbitrary surfaces lies in its potential to enhance patient-specific musculoskeletal models. By enabling muscle paths to directly conform to bone shapes extracted from medical image data, this technique opens up new possibilities for more precise surgical planning and clinical assessments of gait and movement.
