What is a muscle strain? What's it commonly known as? |
Over-stretching or tearing of the muscle fibrils or tendon (PULLED MUSCLE) |
|
What causes a muscle strain? |
Joint forced past its normal range. |
|
Difference between STRAIN and Tear? |
Muscle is still whole. |
|
Most common muscle strains? |
Hamstring and back |
|
How does a muscle strain repair itself? (2) |
Blood supply to muscle still sufficient to provide good healing. Activated satellite cells divide slowly and fuse with fibres to assist repair. |
|
What a risk in a muscle tear? |
Local separation of tissue meaning a defective blood supply. |
|
Whats a complication of a MUSCLE TEAR? |
Muscular Fibrosis - damaged tissue is replaced by fibrous connective scar tissue |
|
What is FIBROMYALGIA? (3) |
Chronic, widespread muscle and connective tissue pain, joint stiffness and fatigue. |
|
What other symptoms may someone with FIBROMYALGIA have? |
Unexplained anxiety or depression. |
|
Whats the criteria for diagnosing FIBROMYALGIA and why? |
- Pain on palpitation must be present in at least 11 of the 18 points. -Medically unexplained and lacks scientific consensus so controversial to diagnose. |
|
Causes of fibromylagia? (4) |
Stress, trauma, damp, poor sleep. |
|
Symptoms of FIBROMYALGIA (6) |
Pain at specific tender spots. Stiffness of muscles, tendons and ligaments. Debilitating fatigue & sleep disturbance. Difficulty swallowing Numbness Cognitive disfunction |
|
Most likely to suffer from FIBROMYALGIA |
Men:women 1:15 Aged 25-50 years |
|
How might FIBROMYALGIA be linked to the nervous system |
Caused by abnormalities in pain processing by the Central Nervous System |
|
What is MUSCULAR DYSTROPHY? |
Group of inherited muscular diseases that weaken and degenerate the muscles. |
|
How is MUSCULAR DYSTROPHY generally characterised? |
- Defects in muscle protein. -Progressive skeletal muscle atrophy -Death of muscle cells |

|
What is the DISEASE process of DUCHENNE MD? Caused by absence of what? |
Gradual atrophy of skeletal, heart and respiratory muscles. Dystrophin (a protein that helps keep muscles intact) |
|
Which muscles are most affected by DUCHENNE MD? |
External mobiliser muscles. |
|
Prognosis for DUCHENNE MD? |
No cure most die under <20 due to respiratory weakness. |
|
Cause of MYOTONIC CONGENITAL MD? |
Inherited dominant gene (just one gene to get it) |
|
Disease process for MYOTONIC CONGENITAL MD? |
