  Microtrauma
Microtrauma is the general term given to small injuries to the body.
One example of microtrauma is in the form of microtears to the muscle fibres as a result of stresses the body is not accustomed to - such as an intensive workout.
Because of the slow and progressive onset of this internal injury, the condition is often ignored until the symptoms become acute, often resulting in disabling injury.

 A Guide To Detecting Nail Pathology
Whether the stimulus is microtrauma, psoriasis, onycholysis, lichen planus or squamous cell carcinoma, nail bed keratinization may result in “dystrophic nails” that are clinically indistinguishable.
Given that microtrauma alone may play a significant role in the pathogenesis of nail unit dystrophy and in serving as the most common precursor for the development of onychomycosis, one should assess its potential role in the development of nail unit dystrophy in all individuals with keratinizing (type 2 or type 4) nail unit dystrophy.
Once microtrauma is fully entrenched in the cycle of nail bed keratinization, eradicating the fungal infection alone may not result in a clinical cure but would facilitate a mycologic cure in the face of a clinical failure.

 Athletic Body in Balance by Gray Cook
Microtrauma results from small amounts of stress imposed on the body over time caused by poor biomechanics and overtraining.
Most blame microtraumas on overtraining and not enough rest and recovery, but this often is not the case.
Microtrauma can be the result of overtraining, but multiple factors are associated with microtrauma-inadequate warm-up and cool-down, lack of body awareness, poor nutrition and hydration, as well as suboptimal biomechanics.

Microtrauma occurs as a repeated injury, usually not noticed initially because the injury is microscopic in magnitude, but where the cumulative trauma leads to pain and in some cases, significant disability.
Swimmer’s shoulder occurs when there is chronic overload (microtrauma) of the rotator cuff tendons, leading the weakness and proximal migration of the head of the humerus.
This causes impingement syndrome and pain with the upstroke due to the rotator cuff being impinged by the acromion and coraco-acromial ligament.

 BeyondMass - Powerlifting Injuries - An Overview
Powerlifting injuries are caused by an accuumulation of microtrauma (small amount of muscle injury important for muscle growth and strength) that builds up to macrotrauma (large amount of muscle injury that is not important for muscle growth or strength and will actually stop your training due to pain).
The effects of the microtrauma include the microtearing of the muscle, the sheath around the muscle and the adjacent connective tissue, as well as stress to the tendon and its bony attachments.
Microtrauma causes a corresponding low level of inflammation that cannot be seen or palpated.

 Treating Sports Injuries
Microtrauma is not necessarily a result of a single excessive episode of overload or use.
The majority of microtrauma is due to an accumulation of loading forces on the musculotendinous unit that would cause no damage if it occurred for only a short period.
Damage leading to microtrauma results from repeated application of loading forces to the same musculotendinous units.

 Intravertebral pressure changes caused by spinal microtrauma.
It is known that not all patients with back pain have abnormal lumbar radiographs and, furthermore, microfractures of the endplate may be one of the causes in the origin of low back pain.
Consequently, this study was conducted to determine the interrelationship between microtrauma and intraosseous pressures in the lumbar spine.
The onset of injury was evidenced by the microfracture of one of the two endplates and impregnation of the contrast medium into the spongiosa.

 The Physician and Sportsmedicine: Rotator Cuff Injury
Individuals who have shoulder instability as a result of congenital laxity, repetitive microtrauma (from participation in overhead sports), or macrotrauma place increased demands on the rotator cuff as it attempts to keep the humeral head centered in the glenoid.
A third mechanism of microtrauma to the rotator cuff is tensile failure with throwing.
The fourth and final mechanism of microtrauma is internal or posterior superior glenoid impingement (figure 3) (13).

Instead, the root causes of pain are cumulative microtrauma and dysfunction from repetitive overuse in awkward positions.
Microtrauma involves very minor bodily insults that repair with scar tissue that is less elastic than the unscarred tissue.
Repetitive microtrauma can also be responsible for degenerative arthritic changes in the spine.

 The Maggs Muscle ManagementTM Program
This local hypoxia is believed to be due to the following; during training and competition, or repetitive use of a muscle, microtrauma to the muscle accumulates in the muscle bundles.
This microtrauma leaves the muscle bundles taut, which squeezes the capillary beds and the arterioles closed.
It's critical to fully appreciate the nature of this microtrauma and the ultimate consequence to a muscle.

 Bodybuilding - Wikipedia, the free encyclopedia
Resistance weight training causes microtears to the muscles being trained; this is generally known as microtrauma.
These microtears in the muscle contribute to the soreness felt after exercise, called Delayed onset muscle soreness (DOMS).
It is the repair to these microtrauma that result in muscle growth (anabolism).

 Working With the Injured Runner
The end result is a microtrauma injury - the body is unable to keep up with the repair and re-strengthening needs, so the tissue begins to fail and becomes symptomatic.
If it is not particularly painful (or if the pain is eliminated by painkilling drugs), the runner continues to run, eventually leading to complete failure, such as a stress fracture or ligament tear.
Causes of microtrauma injuries external to the runner are often the easiest to modify, and should be addressed immediately in treatment.

 Welcome to Dr.Squat   (Site not responding. Last check: 2007-11-04)
microtrauma resulting from eccentric contraction (and to a lesser degree with concentric contraction) begins to accumulate because you're not taking proper restorative measures between workouts, or you're engaging too heavily in eccentric work, or both.
microtrauma," being disruptive of the electromechanical impulses that “drive” the contraction process never get to the actin and myosin in sufficient intensity (twitches per second) to generate maximum force.
This being the case, cumulative microtrauma is never tended to, and restoration is never complete, a situation which may indeed result in an overtrained state over weeks of time.

To increase the overall miofibrills cross-section via it's supercompensation after microtrauma has been inflicted the load should be long enough to provide for CP stores exhaustion during the set(the main condition for microtrauma to occur).
So during that stage accumulation of "residual" incomplete restoration occurs, and when intensity reaches it's maximum in the end of the mesocycle volume is decreased by decreasing the number of reps to 2-3 and transition to "restorative" mesocycle follows.
But the goal of this mesocycle is not limited to this process of miofibrilla contractile elements supercompensation-intensity of heavy workouts during this stage is increased from 80% to 100% and that affects muscle ability to maximally mobilize all motor units and "teaches" tendons and ligaments to sustain limit loads.

At the same time he was pursuing his microtrauma claim under the Workers' Compensation Act, Grenz was also pursuing a companion claim for occupational disease benefits.
That claim, which was also based on microtrauma occurring subsequent to the elbow injury, was presented to the Department, which concluded that it also was time barred.
Grenz's argument herein is that his 1984 claim encompassed not only an elbow injury but disease inducing microtrauma suffered at work prior to his injury.

It is not uncommon for this "weekend warrior" to try to make up for lost time by not warming up properly or by playing harder and longer, and this makes him or her more susceptible to injury.
The middle-aged athlete's muscle tissue is more susceptible to injury with less direct trauma and microtrauma than the tissue of a younger athlete because it is less elastic with less overall blood supply.
Typically, by the time we see this patient in the office his or her history is of shoulder pain that developed gradually (unless there was a precipitating acute traumatic injury) over a period of several weeks.

 Abstract Archvive
Objective: To better understand the pathogenesis of TMD by studying microtrauma of the temporomandibular joint (TMJ), immune responses within TMJ, and psychosocial factors of the past ten years.
Results: Persistent and recurrent microtrauma did exist within joints of TMD patients, caused by occlusal trauma and occlusal interference.
Conclusion: Microtrauma of TMJ, immune responses within TMJ, psychosocial factors, and anatomical structures of the TMJ itself are the four main contributing factors of TMD.

 Suggested Causes and Treatments of Fibromyalgia
Microtrauma caused by or resulting from hypoxia, ischemia, stress, prolonged muscle spasm,local muscle abnormalities was suggested after studies showed nonspecific ultrastructure changes in the muscles of fibromyalgia patients.
Apart from local muscular pain caused by overuse or inflammation (with local irritation of nociceptors) and apart from referred pain (with pain radiating in a segmental pattern), there may be a third type of pain in the muscular system: centrally controlled tendomuscular pain (CCTMP) called tendomyose.
The secretion of growth hormone occurs primarily during stage 4 sleep and this in turn results in a rise in somatomedin C. Serum levels of somatomedin C were found to be significantly lower in 70 fibromyalgia patients compared to 55 healthy controls.

The Court held that his claim was time-barred and rejected his argument that the insurer and employer were estopped from raising the limitations defense.
It was only after he had lost his case concerning the elbow injury in 1991 that he asserted that the arthritis was caused by a series of microtraumas un-related to the elbow injury.
The employer and insurer were completely unable to investigate the claim and prepare a defense to the microtrauma injury until 1992, seven years after Grenz had ceased working at American Stud.
