grade 1 muscle injury
mild pain / swelling
pain with tissue tension
grade 2 muscle injury
moderate pain swelling
- activity modification
focally tender to palpation
grade 3 muscle injury
near - complete tear with severe pain
palpable defect
- joint instability
inflammatory stage of healing
3-5 days
- immediate
vascular changes, clot, remove wastes and import blood into mm
treatment principles
- acute muscle injury
optimal loading
prevention of secondary effects
precautions inflammatory stage treatment
overloading of tendon
proliferative phase
48 hrs to 6-8 weeks
new collagen being laid
treatment principles
- proliferative phase
restoration of normal tissue function
optimal loading
avoiding complications
explain precaution of treatment during proliferative phase
movement faults (pain, weakness, lack of ROM)
– may need to correct
remodeling stage of acute mm injury
continuous process for the next 1-3 years
treatment principles of remodeling phase injuries
optimal loading while returning to function
muscle tear timeline

ligament tear timeline
- grade 3
5 weeks to >1 year
bone injury / fx timeline
6-12 weeks
cartilage injury timeline

possible chronic mm interventions
possible causative factors
reduce stress to tissues
regain structural integrity
resume optimal function and prevent reoccurrence
soft tissue myofascial release
indication
loss of function secondary to ischemia, guarding, revascularization
benefits of myofascial techniques
autonomic stimulation via skin and superficial fascia
histological/mechanical changes in soft tissue
