Many sports involve aligning a hitting implement with a ball trajectory such that contact is made at the implement's center of percussion or 'sweet spot'. This spot is not visibly distinct; its perception must be haptic. Although it is functionally defined with respect to contact--it is the point of impact that produces the least vibration in the hand holding the implement--hitting success requ...

BACKGROUND The on-field diagnosis of sports-related concussion (SRC) is complicated by the lack of an accurate and objective marker of brain injury. PURPOSE To compare subject-specific changes in the astroglial protein, S100B, before and after SRC among collegiate and semi-professional contact sport athletes, and compare these changes to differences in S100B before and after non-contact exert...

The number of people both young and old engaging in sporting activities has increased in the recent times. Apart from the economic benefits of sports which drive youths to engage in competitive sports, adults and seniors are now aware of the health benefits of recreational sports. Inactivity has been linked to many chronic diseases including cardiovascular disease which is leading cause of deat...

OBJECTIVE To determine the baseline injury rate for children ages 7 to 13 participating in community organized baseball, softball, soccer, and football. METHODS In this observational cohort study, 1659 children were observed during 2 seasons of sports participation in an urban area. Data were collected by coaches using an injury survey tool designed for the study. A reportable injury was defi...

Objective -To determine the pattern of injuries sustained by taekwondo competitors, and how previous injury affects performance in sporting competition. Methods Competitors at a major New Zealand fullcontact taekwondo tournament were given a comprehensive questionnaire immediately before competition. Self reports of injuries sustained through taekwondo in the previous 12 months were determined....

In an 8-year retrospective study, 631 injuries due to the racquet sports of squash (59%), tennis (21%) and badminton (20%) were seen in a sports injury clinic, males predominating (58 to 66%). The proportion of squash injuries was higher than expected and probably relates to higher physical stress and risk of contact in this sport. Also they occurred mainly in persons over 25 years (59%) i.e. t...

Performing sports after total hip arthroplasty (THA) may be associated with a risk of Trauma (fracture and dislocation)Shorter implant survivalThere is no proof that trauma occurs more often than in healthy individuals, but sequelae may be more severe.Shorter implant survival due to repetitive high contact forces is a fact, due to increased wear. The 15 year survival in highly active patients s...

Burner or stinger syndrome is a rare sports injury caused by direct or indirect trauma during high-speed or contact sports mainly in young athletes. It affects peripheral nerves, plexus trunks or spinal nerve roots, causing paralysis, paresthesia and pain. We report the case of a 57-year-old male athlete suffering from burner syndrome related to a lumbar nerve root. He presented with prolonged ...

Background Sports-related concussion (SRC) results from abnormal traumatic forces applied to the brain, resulting in temporary alteration in neurological functioning. At the time of injury, such forces also are applied often to the cervical spine, placing the athlete at risk of a coexistent cervical spine injury. Spinal cord injury without radiographic abnormality (SCIWORA) is a unique form of ...
