Lecture 14 Timing of Strength adaptations: change of the neural adaptation contributing the strength after all with muscle configuration Soft & Hard Tissue Injuries Types of injuries Acute vs chronic injuries: sudden/specific mechanism vs slow/long term (commonly by overuse) Common soft tissue injuries: Open vs Closed Common hard tissue injuries: injuries to bones/joints: Soft Tissue Injuries - Open injuries: Abrasions: scrapes common injury Treatment: use of running water to clean, use of antibiotic ointment to prevent infection, but use of air if there is no fluid or blood leaking, & cool towels to relieve pain Lacerations: minor cuts Treatment: stop bleeding by use of gauze, direct/constant pressure & use of antibiotic ointment; apply daily if needed *uncontrolled bleeding requires immediate medical attention  if it is deep there should be stitches (more than an half inch wide and half inch deep  if not treated - pus or redness, burning will start *depending on time there is smell of blood Avulsions: very deep injury where lots of skin layers are torn off completely or only a flap of skin remains lots of bleeding & often scarring Treatment: after cleaning wound, requires skin to remain if there is and place back into original position severe avulsions definitely need stitches Puncture wounds: sharp object penetrating -it is harder to clean and highly risky to treat it Treatment: find out if any part of object is still in the wound & know if other soft tissues have been injured  if there is something in there, requires leaving it inside to prevent more damage/bleedingseek profession ASAP Soft Tissue Injuries - Closed injuries: Injuries to Muscles/Tendons: result from internal/external forces/causes  there can be internal injuries by the forceful movement of the body and allowing applied forces **usually we have lots of blood circulation within muscle –allowing much faster heal *scar tissue results in tight, inelastic tissue Contusions: bruises  site of the contusion from injury to the broken blood vessels in the area  result from direct compressive force  has 3 degrees of more damage to the tissues -associated with swelling, redness, pain on palpation Treatments: rest, cooling-ice, anti-inflammatories use  but there is some new recommendation that looks at how ice may slow down the time of the healing processes Rehabilitation: physical therapy & exercise to increase ROM, restore function & strength -if not treated scar tissue may form *return to full activity when strength & ROM recovered *taping +massaging can be used as well Strains: over-stretchin
