OBJECTIVE: To evaluate and compare the effects of 2 manual therapy interventions
on cervical spine range of motion (ROM), head repositioning accuracy, and balance
in patients with chronic cervicogenic dizziness. DESIGN: Randomized controlled
trial with 12-week follow-up using blinded outcome assessment. SETTING: University School of Health Sciences. PARTICIPANTS: Participants (N=86; mean age
+/- SD, 62.0 +/- 12.7 y; 50% women) with chronic cervicogenic dizziness.
INTERVENTIONS: Participants were randomly assigned to 1 of 3 groups: sustained
natural apophyseal glides (SNAGs) with self-SNAG exercises, passive joint
mobilization (PJM) with ROM exercises, or a placebo. Participants each received 2
to 6 treatments over 6 weeks. MAIN OUTCOME MEASURES: Cervical ROM, head
repositioning accuracy, and balance. RESULTS: SNAG therapy resulted in improved
(P </=.05) cervical spine ROM in all 6 physiological cervical spine movement
directions immediately posttreatment and at 12 weeks. Treatment with PJM resulted
in improvement in 1 of the 6 cervical movement directions posttreatment and 1
movement direction at 12 weeks. There was a greater improvement (P<.01) after
SNAGs than PJM in extension (mean difference, -7.5 degrees ; 95% confidence
interval [CI], -13 degrees to -2.0 degrees ) and right rotation (mean difference,
-6.8 degrees ; 95% CI, -11.5 degrees to -2.1 degrees ) posttreatment. Manual
therapy had no effect on balance or head repositioning accuracy. CONCLUSIONS:
SNAG treatment improved cervical ROM, and the effects were maintained for 12
weeks after treatment. PJM had very limited impact on cervical ROM. There was no
conclusive effect of SNAGs or PJMs on joint repositioning accuracy or balance in
people with cervicogenic dizziness.
