Kinematics of an instep soccer kick

What does it take to kick a soccer ball? The biomechanical explanation may be a lot more complex than one suspects. The movement of an athlete kicking a soccer ball can be broken down into proximal (close to torso) to distal (away from torso) sequences of body segment motion. Various aspects of the soccer strike of a ball have been studied and analyzed. Due to the complexity of the movement, varying methodologies and application of inverse dynamics, there are differences in the understanding of the moments and angles involved in an instep kick of a ball such as one seen during a free kick.

Preventing ACL injuries through jump assessment

Basketball is a fast-paced and aggressive sport. These qualities which make the game so exciting to watch are also what contributes to a high rate of injury such as an anterior cruciate ligament (ACL) tear. What’s more, the ACL injury incident rate for female basketball players is more than three times the rate of male basketball players. How can we lower the risk of an ACL injury? A research team from France explored this question with specific physical training based on jump assessment.

Quantified relief for failed back surgery syndrome patients

Chronic back pain is a prevalent condition which has significant and direct effects on the daily life. Many individuals undergo surgical intervention in hopes of pain relief, but unfortunately some patients still experience chronic back, neck or limb pain after back surgery. This condition is known as “Failed Back Surgery Syndrome.” To address the pain, an integrated approach is often implemented, utilizing pharmacologic pain management as well as physical and behavioral therapy. When this multidisciplinary approach does not work, neuromodulation therapies are used such as spinal cord stimulation (SCS).

Integrated computational analysis of the pelvis

In order to fully address pathologies affecting the movement and gait, there must be an understanding of the causes and effects of musculoskeletal disorders. To model the mechanical behavior of joints, muscles and skeletal tissues, two methods of computational modeling have arisen. The first is musculoskeletal modeling in which mechanical principals are utilized for describing the motion of a body which is modeled as a system of rigid bodies.  The second is the finite element (FE) method which utilizes mathematical modeling and solving of complex equations for analysis.

Addressing anxiety in post-stroke patient

It is well known that strokes often have serious, lasting effects on patients as discussed in a previous post. While the cognitive complications from stroke may be more commonly heard of, psychological effects of stroke are possible and common for post-stroke patients. Such effects like anxiety and depression are thought to be attributed to the physical injury and disruption of the brain, decreased quality of life from the stroke, and/or a combination of preexisting personality traits. Anxiety after a stroke is common among post-stroke patients and persistent, as it can be further complicated by changes in cognitive function.

Motion tracking and analysis of drawing

Many children have learning disabilities such as dyslexia and the inability to write coherently known as dysgraphia. To many, dyslexia and dysgraphia may seem to only relate to reading, speaking and writing; however, the results of research have helped to provide a better understanding of these learning disabilities.  Past studies and literature have shown that children with dyslexia often experience difficulties with fine and gross motor skills (Capellini et al., 2010). This can manifest in complications with coordination and balance as well as general ‘clumsiness.’
