Acceleration where cavitations occur:
72 deg per second
Reaction time of patient during SMT:
200 ms
Force needed for C-spine SMT
118 N
Force needed for Tspine SMT
238 N
Duration of thrust according to Herzog et al 1993:
80-100ms (cervical), 200 ms (lumbar)
Average number of cavitations during C3-4 SMT according to Reggars 1996:
2.5
Duration of thrust to thoracic/SIJ according to Hersoz et al 1993:
120-200 ms
Average error from targeted thoracic segment according to Ross et al 2004:
3.5 cm
Average error from targeted lumbar segment according to Ross et al 2004:
5.29 cm (0-14 cm)
Did Beffa and Mathews 2004 demonstrate a significant difference in target joint cavitation for L5/S1 or SIJ:
No; L5/S1 cavitated L3/L4 and SIJ cavitated L4/L5
According to Bolton et al 2007, performing C3-4 SMT with rotation caused cavitations on which side?
contralateral to the aplicator
According to Bolton et al 2007, performing C3-4 SMT with sidebending thrust caused cavitations on which
side?
No more likely to occur on ipsilateral vs contralateral to applicator
Gal et al 1997 found how many mm of movement to occur at T10, T11, T12 with prone PA thrust to right TP?
6-12 mm anteriorly
3-6mm in left lateral translation
