Q

Can you use a manual wheelchair with a quadriplegic?

A

Yes it might be possible. Quadriplegict just means all four limbs are involved, not neccesarily useless.

Q

Can a C7 SCI patient walk?

A

there is new technology where we can imbed electrodes into leg muscles on a walker that are being created. Problem is there is no sensory feedback or correction

It is wireless now

Q

Cauda Equina Injruies

A
  • •Can be complete, usually incomplete
  • •LMN lesion- significant due to possible regeneration
  • •MOI- traumatic fracture or dislocation

Has the potential to regenerate because it is a lower motor neuron

27
Q

Clinical Manifestations of SCI

A

•Spinal Shock

  • –Post injury areflexia
  • –Hours to weeks symptoms resolve (acute care)

•Motor and Sensory Impairments

  • –Complete or partial loss below level of injury ie. C7 and below

•Body temperature regulation

  • –Hypothalamus can not control blood flow or sweating
    • •Diaphoresis (excessive sweating) above level of lesion

•Respiratory dysfunction

  • –C1 and C2 possibly C3 lesions- phrenic nerve loss
    • •Ventilator
    • •Risk for pneumonia, pulmonary embolism, infections, atelectasis
    • •Coughing, deep breathing, accessary muscle issues

•Spasticity

  • –Hypertonicity, hyperactive stretch reflex and clonus
    • •Can help or hurt with function
    • •Can be treated with medication
      • –Nerve blocks, intrathecal injections
    • •Surgeries for spasticity
      • –Myotomy- muscle release
      • –Neurectomy- cut involved nerve/s (partial or complete)
      • –Tenotomy- lengthening of a tendon

Clinical Manifestations (continued)-Bowel and Bladder dysfunction (see another slide for details)

28

    • •Diaphoresis (excessive sweating) above level of lesion
31
Q

A
  • –C1 and C2 possibly C3 lesions- phrenic nerve loss (if pt lives)
    • •Ventilator
    • •Risk for pneumonia, pulmonary embolism, infections, atelectasis
    • •Coughing, deep breathing, accessary muscle issues
32

A

•Bladder- UTI risk due to lack of muscle tone

  • –UMN spastic bladder- automatic or reflex voiding- suprapubic stimulus may elicit this
  • –LMN flaccid bladder (caudia equina)- Valsalva or manual abdominal pressure to elicit voiding

35
Q

Bladder training programs (or what you must use instead)

A

36
Q

List some Indirect Impairments & Complications (9)

A

37
Q

Indirect impairments and Complications: Autonomic dysfreflexia

A

•Autonomic dysreflexia- can kill your patient

  • •Symptoms- increased BP, decreased HR, HA, sweating, spasticity, restless, flushing- due to vasodilation above lesion, vasoconstriction below lesion, pupil constriction, nasal congestion, piloerection, blurred vision, syncope.
    • •Intervention- Check cath, sit up if lying down (raise the head), loosen clothing and abdominal binders, get help!
  • MAKE SURE YOU NEVER EVER PUT CATHETER BAG ABOVE BLADDER
38
Q

Indirect impairments and complications: Pressure sores

A

•Pressure sores- pressure or shearing forces combined with bowel and bladder dysfunction, decreased sensation, etc.

  • –Location- bony prominences
  • –Best treatment is prevention- turning schedules, pressure relief, skin care
39
Q

Indirect impairments and complications: Postural Hypotension

A

•Postural hypotension (orthostatic hypotension)- decrease in BP supine to sit or sit to stand

  • –Tilt table progression, compression hose, abdominal binder, gradual progression
40
Q

Indirect impairments and complications: Heterotopic ossification

A

•Heterotopic ossification- growth of bone outside the skeleton ie. muscles, tendons, connective tissue

41
Q

Indirect impairments and complications: Contractures

A

•Contractures- change in muscle length, change in capsular and pericapsular structures

42
Q

Indirect impairments and complications: DVT

A

•DVT- can cause death if thrown- pulmonary embolus

  • –Loss of muscle pump, stasis of blood, increase in thrombin
    • •Symptoms- swelling, erythema, heat
    • •Intervention- Drugs, hose, turning program, ROM, elevation of LE’s
43
Q

Indirect impairments and complications: Pain

A

–Traumatic pain- injury ie. MVA, fall, etc.
–Nerve root pain- radiating, burning, etc.
–Spinal cord Dysesthesias- Deep pain from areas that lack sensation
–Musculoskeletal pain ie. shoulder, elbow, or wrist pain from assistive device with walking or W/C propulsion, transfers, etc.

44
Q

Indirect impairments and complications: Osteoporosis & REnal Calculi (kidney stone)

A

•Osteoporosis and Renal Calculi (kidney stone)

  • –Calcium metabolism issues- break down bone, increased calcium in blood, deposits in kidney
