People call any muscle or tendon injury a strain, and it can occur due to sudden unaccustomed or abrupt action or movement, direct trauma, or overstretching of muscles due to indirect trauma, especially in sportspersons.
Types
- acute strain: this is due to sudden violent force or direct trauma
- chronic strain: this is due to injury existing since a long period leading to muscle ischemia and fibrosis
Pathophysiology
injury to the muscles leads to pain. as a results, the muscle goes into spasm to limit the movements and reduce pain. nevertheless, paradoxically, this protective muscle spasm causes pain due to stimutation of pain fibers and thus a vicious cycle sets in. the painful stimuli causes muscle spasm through the peripheral nociceptive stimuli
treatment goals
For First 24 Hours
- immediate application of ice
- compression bandage
- limb elevation
- limb immobilization in splints
- Isometrics to the muscles, which are immobilized, are made.
- active exercises to the unaffected joints
- pulsed electromagnetic field therapy (PEMF)
- no active movements to the affected muscles
During the Next 24 to 48 Hours
- Remove the pressure bandage and begin active muscle exercises.
- Commence stretching within the limits of pain.
- thermotherapy: ultrasound, short wave diathermy and TENS helps to relieve pain
- slow rhythmic massaging helps relieve the muscle spasm
- Slowly start non-weight bearing on crutches.
Between 48 and 72 Hours
apart from the measures mentioned above, the additional measures during this phase include:
- Encourage more vigorous active movements
- add deep transverse friction massage
- permit partial weight bearing
After 72 Hours
- remove pressure bandage
- progressive resisted exercises using the fowler technique by taking out 10 to 12 repetition maximum, is practice
- permit full weight bearing exercises in injuries of the lower limb
- After regaining full movement, allow the individual to walk and jog
- Regain full functional activity within 4 to 6 weeks.
the various drugs which can be while the treatment of muscle stain are
- analgesic anti-inflammatory drugs
- muscle relaxants
- psychotropic drugs
- beta-blockers
- ointments
