Q

When defining levels of injury, what is the difference between the Orthopedic level and the Neurological level?

A

Orthopedic Level: The leve where the greates vertebral damage is found (via radiographic exam)

  • Often does not correlate with the neurological level
  • Not all spinal cord injuries have a bony injury (i.e. tumor)

Neurological level: The most caudal segment of the spinal cord with normal sensory and antigravity motor function on both sides of the body (with normal function above).

Most gain some level of ambulation

  • Caused by penetrating injuries (ie gun shot or stab wounds
  • Hemisection of teh spinal cord
  • loss of movement, position sense (proprioception) on the same side; loss of pain, light touch on opposite side

Q

Explain eveidence for somatosensory treatements (general)

A
  • Findings suggest that consistant use of afferent input improves the motor output of the control mechanisms that have been impaired after SCI
  • There is evidence that a single session of afferent stimuli may be sufficient to induce neuroplastic changes in spinal cord and cortex.

Q

OGT stands for

A

Overground Gait Training (OGT)

28
Q

Overground gait training (OGT) details (3 things)

A
  1. Can be performed using bodyweight-support systems, assistive devices, orthotics/braces, FES, or any combination therein
  2. Frequently requires multiple therapists/technicians for safety and facilitation
  3. Can result in fewer repetitions due to patient fatigue
29
Q

What is FES?

A

Stands for Functional Electrical Stimulation

Functional Electrical Stimulation (FES) applies small electrical pulses to paralyzed muscles to restore or improve their function. FES is commonly used for exercise, but also to assist with breathing, grasping, transferring, standing and walking. FES can help some to improve bladder and bowel function. There’s evidence that FES helps reduce the frequency of pressure sores. (http://www.christopherreeve.org/site/c.mtKZKgMWKwG/b.4453425/k.27A5/Functional_Electrical_Stimulation.htm)

Seems the same as NMES to me

30
Q

What does the literature say about the use of OGT vs BWSTT vs RGT? (6)

A
  1. BWSTT and RGT can provide appropriate, task-specific, high-intensity afferent input to stimulate spinal and suprasipnal plasticity
  2. Individuals with slowest gait speeds show greates timprovements
  3. Both BWSTT and RGT can increase walking speed, level of independence, and interlimb coordination
  4. OGT may be as effective as BWSTT and RGT
  5. Improvements in gait speed, distance, LE strength, quality of life, and dependence on assistive devices were similar regardless of the locomotr approach
    1. insufficient evidence to conclude that one is more effective than another
  6. Combining electrical stimulation may improve outcomes of all locomotor training

What does the literature say about Exoskeletons? (4)

A
  1. Generally found to be safe, effective in getting people with SCI up and walking
  2. Monor skin abrasions common, more serious issues rare
  3. Speeds vary widely with injury level and other factors
    • flrequently mouch slower than able-bodies speeds
    • Questionable ability to reach community ambulation speeds
  4. FDA currently requires a companion for use outside of rehabilitation setting
39
Q

Potential Benefits for use of Locomotor Technologies (4)

A
  1. Allows earlier interveintion with more acute/medically involved clients
  2. Allows for increased intensity and number of repetitions

40
Q

Potential Barriers for use of Locomotor Technologies (6)

A
  1. Cost
  2. Space
  3. What your facility has

41
Q

Locomotor Technologies: Limitations in Current Literature (5 points)

A
  1. Lack of large scale randomized control trials (RCT’s)
  2. Studies often done in a limited, chronic SCI population
  3. Often difficult ot match training intensity/duration
  4. Comparisons of technologies not true to how commonly used in rehab
  5. Currently-available literature does not negate clinical reasoning, judgement, and experience
42
Q

Two conclusions/take-home messages about Locomotor Training

A
  • Locomotor training should begin as soon as possible, should always be challenging, with only minimal support from therapists or robotic devices, and with full patient participation
  • Aim to optimize task-specific sensory cues to facilitate spinal and supraspinal plasticity, including arm movemenets and appropriate manual cuing

A

Justic Oliver Wendall Holmes

He justaposed the country’s “best citizens” (nondisabled persons) with those who “sap the strength of the state” (disabled people), and to avoid “being swamped with incompetence,” ruled “It is better for all the world, if instead of waiting to execute degenerate offspring for crime, or to let them starve for their imbecility, society can prevent those who are manifestly unfit from continuing their kind.”

A
  1. Tell them how the segregation and exclusion of people with disabilities all began.
  2. Tell them how, historically, a lot of important decision-makers passed laws sending disabled persons away.
  3. Lastly tell them progress is being made.
