A repetitive strain injury (RSI) is an injury to part of the musculoskeletal or nervous system caused by repetitive use, vibrations, compression or long periods in a fixed position. [1] Other common names include repetitive stress injury , repetitive stress disorders , cumulative trauma disorders ( CTDs ), and overuse syndrome .
Nerve entrapment involves a cascade of physiological changes caused by compression and tension. Some of these changes are irreversible. [1] The magnitude and duration of the forces determines the extent of injury. [2] In the acute form, mechanical injury and metabolic blocks impede nerve function.
A strain can occur as a result of improper body mechanics with any activity (e.g., contact sports, lifting heavy objects) that can induce mechanical trauma or injury. Generally, the muscle or tendon overstretches and is placed under more physical stress than it can withstand. [ 1 ]
These injuries are associated with diving injuries, falls and car accidents. [18] Anterior compression vector results in mild height loss, whereas hyper-extension often occurs with the posterior displacement of the head in car crashes. [18] Severe hyper-extension injury leads to pinching of the spinal cord along the posterior margin of the body ...
Following nerve injury, the nerves undergo degeneration before regenerating, and other pathways can be strengthened or reprogrammed to make up for lost function. The most common form of peripheral nerve injury is stretching, due to their inherent elasticity. Nerve injuries may also be caused by laceration or compression. [50]
Many of the common injuries that affect runners are chronic, developing over longer periods as the result of overuse. Common overuse injuries include shin splints, stress fractures, Achilles tendinitis, Iliotibial band syndrome, Patellofemoral pain (runner's knee), and plantar fasciitis. Proper running form is important in injury prevention.
When an object is subjected to a force in a single direction (referred to as a uniaxial compression), the compressive stress is determined by dividing the applied force by the cross-sectional area of the object. [1] Consequently, compressive stress is expressed in units of force per unit area. Axial Stress
Traumatic SCI can result in contusion, compression, or stretch injury. [5] It is a major risk of many types of vertebral fracture. [70] Pre-existing asymptomatic congenital anomalies can cause major neurological deficits, such as hemiparesis, to result from otherwise minor trauma. [71]
