Add to cartMacrotrauma=
Microtrauma=
*type of injury (pain, strain, fracture) is determined by the tissue involved (muscle, tendon, bone, joint)
injury-related deficits in neuromuscular control and proprioception are due to:
an injury with an sudden and obvious episode of tissue overload and subsequent damage
an overuse injury (NOT due to repeated activity), due to training errors, suboptimal training surfaces, faulty biomechanics or technique during performence, insufficient motor control, decreased flexibility or skeletal malalignment
microscopic nerve damage in soft tissue (=deafferentation) and disruption in the sensory feedback pathways used for joint stabilization and neuromuscular coordination
input text value
common musculoskeletal injuries
- muscle contusion (kneuzing)
- muscle strain (spierpijn)
- tendinopathy
- tendinitis
- tendinosis
- ligament sprain (verstuiking)
- joint dislocation
- osteochondrosis
- osteoarthritis
- bursitis
- bone fracture
- bone stress fracture
- bruise; occurs from a sudden and forceful blow to the body; formation
- abnormal muscle action leading to a stretching or tearing of the muscle fibers
- collective effects of tendinitis and tendinosis
- inflammation of a tendon (when not fully healing; tendinosis)
- further breakdown and structural degeneration of the injured tendon
- trauma to tissues that connect bones and contribute to joint stability; occur when an excessive force results in the joint moving beyond its anatomical limits and stretching the ligament
- when a synovial joint moves beyond its normal anatomical limits; subluxation (partial) and luxation (complete)
- degenerative changes in the epiphyses of bones; during growth in children
- degeneration of the articular or hyaline cartilage in a joint, can occur in any joint but most common in weight bearing joints (hip, knee, ankle)
- bursae are small fluid-filled synovial membrane sacs designed to reduce friction between tissues such as tendon and bone; when irritated, bursa becomes inflamed, resulting in bursitis (hip, elbow, knee and shoulder)
- disruption of a bone due to a direct blow
- microtraumatic injury, may result from an abnormal muscle action, fatigue-related failure in the stress distribution across the bone, dramatic change in exercise or training ground surfacem excessive training volume or both

All tissues follow a pattern of healing that includes three phases:
1.
2.
3.
1. inflammation
2. proliferation or repair
3. remodeling or maturation
input text value
Inflammation:
*after tissues are damaged; mechanical mediators are released; increase blood flow and capillary permeability; causing edema (=escape of fluid into the surrounding tissues), which inhibits contractile tissue function and limits activity. Inflammatory substances stimulate sensory nerve fibers, causing pain; decreased function
If inflammatory does not end within a reasonable amount of time:
goal inflammatory phase:
to achieve these goals:
intitial reaction to injury, necessary in order for normal healing to occur
further healing may not occur, thereby delaying the rehabilitation process
prepare for the new tissue formation
relative rest and passive modalities (incl. ice, compression and elevation)
input text value
Repair phase:
goals repair phase:
allows for the replacement of tissues that are not viable following injury or surgery (scar tissue is formed)
prevent excessive muscle atrophy and joint degeneration of the injured area, promote collagen synthesis and avoid disruption of the newly formed collagen fibers
input text value
Remodeling phase:
*production of collagen fibers has decreased, allowing newly formed tissue the opportunity to improve its structure, strength and function (increased loading; hypertrophy, increasing strength)
tissue remodeling can last up to:
goal remodeling/final phase:
by:
the weakened tissue produced during repair is strengthened during the remodeling phase of healing
2-4 months or even beyond one year after injury
optimizing tissue function
continuing the exercises performed and adding more advanced, acitivity specific exercises that allow progressive stresses to be applied to the injured tissue

contraindication=
precaution=
an activity that will benefit the injured client
an activity or practice that is inadvisable or prohibited because of the given injury
an activity that may be performed under supervision of a qualified PT and according to client limitations and symptom reproduction
