Objective To investigate the effect of neck muscle vibration on the unilateral spatial neglect after stroke, and to evaluate its short-term effect.
Methods Fourty patients of stroke with unilateral spatial neglect, including 23 cerebral infarction and 17 cerebral hemorrhage, in Rehabilitation Department of Qixia District Hospital from December 2016 to October 2018 were randomly divided into control group (
n=20) and vibration group (
n=20). Both groups accepted general rehabilitation for unilateral spatial neglect, while vibration group accepted neck muscle vibration treatment in addition. The vibrator was set at frequency 108 Hz, amplitude 1.0 mm, and the vibration point was located in left trapezius for once a day, 15 minutes at a time. Before and 3 weeks after training, the patients in both groups were assessed by the Chinese behavioral inattention test-Hong Kong version (CBIT-HK) scale, after which we respectively compared routine test score, behavioral test score and total score.
Results After 3 weeks, the routine score, behavior score and total score of the two groups were all improved, and the difference before and after treatment was statistically significant (all
P<0.05). In the vibration group, the value of routine score difference, behavior score difference, and total score difference were 19.80±18.51, 15.40±14.82, and 35.10±29.62, respectively. Meanwhile, the corresponding scores of the control group were 10.70±12.10, 3.76±7.28 and 14.45±14.89, respectively. The
t-test of inter-group comparison shown that the behavioral score difference was
t=3.155,
P<0.05 and the total score difference was
t=2.786,
P<0.05. The behavioral and total scores in vibration group were significantly increased. There was no statistically significant difference between the routine test score of the two groups (
t=1.841,
P=0.074).
Conclusion The neck muscle vibration treatment combined with general rehabilitation treatments can improve short-term symptoms of unilateral spatial neglect after stroke.
