Spinal Cord Injury Flashcards
What function does the DCML have?
Vibration, Proprioception, 2 Pt Discrimination, Stereognosis, Barognosis, & Graphesthia
What is the function of the Spinothalamic Tract?
Anterior: Crude Touch
Lateral: Pain & Temperature
What is the function of the corticospinal tract?
Motor tract
What is affected during Posterior Cord Syndrome?
DCML caused by medical error
What is affected during Anterior Cord Syndrome? Cause?
Corticospinal and Anterior lateral Tract caused by HyperFLEXION injury
What is affected during Brown Squared Syndrome?
Left or Right side of DCML, Corticospinal, and Spinothalamic tracts caused by Stab wound or gunshot
What is affected during central Cord Syndrome? Small Lesion?
Bilateral effects of pain and temperature due to tracts crossing caused by HyperEXTNENSION injury
What is affected during central Cord Syndrome? Large Lesion?
DCML, Corticospinal Tract, and anterolateral tract bilaterally (UE more than LE) caused by HyperEXTNENSION injury
Why do lumbar punctures occur at L3-L4?
Spinal Cord ends at L1 so we would avoid damaging spinal cord
Describe Location, Sensory, Motor, and Type of Conus Medullaris?
Location: Bilateral and Symmetrical in perineum and thighs
Sensory: Saddle distribution bilateral & symmetrical
Motor: Symmetric
Type: UMN & LMN
Describe Location, Sensory, Motor, and Type of Cauda Equina?
Location: Unilateral and asymmetrical in perineum, thighs, leg and back
Sensory: Saddle distribution, unilateral and asymmetric
Motor: Asymmetric
Type: LMN
ASIA A Complete
No motor or sensory function at S4-S5
ASIA B Incomplete
Sensory but no motor function present below NLI and S4-S5
ASIA C Imcomplete
MORE than HALF of key muscles function below the single NLI muscle grade of LESS than 3 (most muscles are weak)
ASIA D Incomplete
AT LEAST HALF (half or more) of key muscles functions below the single NLI having a muscle grade GREATER than 3 (most muscles are strong)
