Response of Tissues to disuse and remobilization Flashcards
True or False
Most changes of muscle immobilization are reversible
True
What time frame should be used for remobilization of muscle?
Twice the duration of immobilization
What muscles are most affected by CCL rupture/repair
Quadriceps, Biceps femoris, Semimembranosus
Following surgery for CCO rupture what muscles should be targets and what is the goal?
Quadriceps and Biceps
Improve muscle mass and strength
How long should rehab continue after CCL surgery?
At least 5 weeks
What type of changes does disuse create in cartilage?
Atrophic and degenerative changes
Does immobilization in extension or flexion result in more reversible changes and why?
Flexion does not lead to OA type changes but atrophy of cartilage occurs which is more reversible than increased muscle contraction and OA type changes in extension.
True or False Return to function should be done quickly to reverse atrophic changes after immobilization
False it should be gradual
What percent of neurons must be intact for muscle fibers to recover?
85%
What type of training consists of repetitive, low intensity contractions which result in changes in oxidative metabolism?
Endurance training
What type of training results in a limited number of contractions that occur against a high mechanical load?
Strength
Which has a more profound effect on ligaments - exercise or immobilization?
Ligaments
What class of antibiotic may contribute to tendinopathies?
Fluoroquinolones
What are the 5 basic principle of rehab following ligament injury?
- Maintain ROM
- Avoid excessive excursions
- Protect damaged ligament/tendon from stress
- Apply low cyclic loads
- Progressively increase freq and magnitude of loading
What position can help prevent bone loss?
Standing/weight bearing
