Study Notes
TOPIC 1: MUSCLE INJURY GENERALITIES
- Skeletal muscle, also called striated muscle, is composed of muscle fibers varying in length and diameter.
- Muscle fibers contain nuclei at the periphery and myofibrils with alternating actin and myosin.
- Type I (slow-twitch, red fibers) use oxygen for energy and are resistant to fatigue.
- Type II (fast-twitch, white fibers) primarily use anaerobic metabolism.
- Muscle fibers are organized into three layers of connective tissue: epimysium, perimysium, and endomysium.
- The myotendinous junction is where muscle transitions to tendon, responsible for force transmission.
- Muscle injuries are often categorized as destruction, repair, and remodelling phases.
- Muscle repair is a complex process involving various mechanisms like clot formation, fibroblast action, and activation of satellite cells.
- Muscle injury timelines differ between muscle and tendon. Healing time varies depending on the type of muscle damage.
TOPIC 2: FASCIA
- Fascia is a connective tissue with collagen types I and III.
- Fascia surrounds muscles, tendons, bones, vessels, and nerves.
- Fascia plays a role in movement control, protection, and nutrition.
- Fascia contains mechanoreceptors and nociceptors that respond to pressure, vibration, and temperature
- Fascia is involved in muscle function, mechanical efficiency, and muscle strength.
- Fascia helps maintain body posture.
- Diseases associated with fascia include iliotibial band syndrome, fibromyalgia, and plantar fasciitis.
MUSCLE PATHOLOGY
- Muscle injuries are caused by fatigue, dehydration, lack of electrolytes, and improper warm-up/cool-down.
- Muscle injuries are categorized into minor muscle problems, strains (overuse), and cramps.
- Muscle strain is categorized into three grades (grade 1 mild, grade 2 moderate, grade 3 severe).
- Muscle cramps are painful involuntary muscle contractions.
- Muscle injuries can lead to pain, swelling, and loss of function.
- Methods to prevent muscle injury include proper hydration, warm-up, and stretching.
TREATMENT
- Treatment for muscle injuries depends on the severity and includes rest, ice, compression, elevation (RICE protocol).
- NSAIDs (non-steroidal anti-inflammatory drugs) may be used to help reduce pain and inflammation.
- Electrotherapy can also be beneficial for muscle recovery.
- Stretching and strengthening exercises are essential for rehabilitation.
- Surgery may be necessary in severe cases.
- Healing times depend on the severity of the damage.
