The influence of coughing on cerebrospinal fluid pressure in an in vitro syringomyelia model with spinal subarachnoid space stenosis

Table 3 CSF pressure wave speed in the spinal SAS/syrinx and maximum rate of SAS pressure rise.

Model	SAS wave speed (m/s) [p-value]	Syrinx wave speed (m/s) [p-value]	Maximum rate of SAS pressure rise (mmHg/s)
SSED	23.6 [0.0004]	24.9 [0.004]	1,700
SSE	155 [0.0001]	118 [0.026]	8,000
SAE	169 [0.0008]	N/A	13,200
SRE	399 [0.0009]	680 [0.051]	10,600

Wave speed and pressure rise were significantly smaller in the distensible model (SSED) than in the rigid models (SSE, SAE, and SRE). SSE, SSED, SRE and SAE as for Table 1.
