Q

What are the signs & symptoms?

A
  1. Acute trauma : pain, swelling, damage to nearby tissues, torn or irritated nerves, damaged ligaments, muscles & tendons
  2. Snapping or popping sound at time of injury
  3. Intense & sickening pain
  4. Deformity until the joint is reduced
  5. External supports
  6. Decreased ROM d/t spasm, edema and pain (acute / early subacute)
  7. Adhesions forming in (early subacute / late subacute)
  8. HT & TPs
  9. Loss of proprioception
  10. Instabilities
  11. Full rom remains restricted & tissue may be cool due to ischemia

Q

What is ischemia?

A

Blood flow is restricted or reduced in a part of the body

17
Q

What are the CI’s & Precautions?

A
  1. Acute traumatic dislocations are a local CI - compensatory focus
  2. Acute / Early subacute :
    - No testing other than pain free AROM
    - Do not completely remove protective spasm
    - No distal circulatory techniques
  3. Subacute / Chronic - limitations in ROM must be respected
  4. Do not place an unstable joint into the position of injury
  5. No joint play if the joint is unstable
  6. If a joint has been surgically repaired, do not restore full ROM in the direction that will stretch the repaired tissue
  7. No frictions with anti inflammatories
  8. No remedial exercises in acute
18
Q

If a dislocation is casted, what should you not apply immediately proximal to the cast?

A

Heat applications

19
Q

Before attempting to restore ROM in the direction of injury, ensure the majority of ______ is regained.
- Increase _____ then ______

A
  1. Strength
  2. Strength, stretch
20
Q

What are assessment findings in acute dislocation?

A
  1. Antalgic gait and/or posture
    - joint dependent
  2. External supports may be place
  3. Possible pained facial expression
  4. Signs of inflammatory may be observed
  5. Protective spasm palpated in muscles crossing the joint
  6. AROM limited (PROM & RROM CI’d in acute) - direction of injury
  7. Likely impact on ADLs
21
Q

What are assessment findings in subacute / post acute?

A
  1. Antalgic gait and/or posture + ADL impacts may persist
  2. External supports are still in place
  3. Pained facial expression
  4. Signs of inflammation decreasing
  5. Adh, HT & TPs palpated in mm crossing the joint
  6. AROM ilmited (PROM & RROM CI’d in subacute)
22
Q

What are assessment findings in chronic?

A
  1. Habituated antalgic gait & posture
  2. External supports may still be in place
  3. AROM limited; if apprehension is shown in the range that caused injury PROM is CI’d
  4. PROM use extreme caution in the range that caused injury; empty end feels due to apprehension
  5. RROM reveal weakness
  6. Palpation findings are similar to late subacute and may show residual edema
23
Q

What are goals?

A

Acute :
- Reduce edema and pain
- Prevent excess adhesion formation
- Maintain function & mobility
Subacute :
- Gradual return to movement within pain tolerance to avoid excess scar tissue formation
- Reduce risk of reinjury via proprioceptive training
Chronic :
- Increase local circulation
- Restore stability via strengthening of muscles that cross the joint
- Normalize mobility & muscle tone
- Reduce TPs & adh

24
Q

What are homecare exercises in acute, subacute/post acute?

A
  1. RICE or PRICES (acute)
  2. POLICE (subacute / post acute)
  3. Breathing exercises for pain reduction (acute & subacute)
  4. Pain free at proximal & distal joints (acute)
25
Q

What are exercises in chronic?

A
  1. No movements that cause apprehension
  2. Stretching
  3. Strengthening (isometric progressing to isotonic)
  4. Self massage or foam rolling
  5. Proprioceptive exercises
  6. Gradual return to activity
