Effect of Activation of Deep Neck Muscles as an Adjunct to Vestibular Rehabilitation in Vertigo

Abstract

Aim: The study was conducted to find effect of activation of deep neck muscles as an adjunct to vestibular rehabilitation in vertigo. Materials and Method: A total 20 subjects (9 males and 11 females) between 18-30 years diagnosed with Vertigo were selected for study considering inclusion criteria. Subjects were grouped into Experimental group (Group A), Control Group (Group B). Group A received exercises for deep neck muscle activation along with vestibular rehabilitation and group B received Vestibular rehabilitation. Each session was conducted for 30 minutes duration, 3 days per week for 4 weeks. Outcome assessment used was Dizziness Handicap Inventory (DHI), Motion Sensitivity Quotient (MSQ) which was assessed pre, post exercise session. Statistical analysis was done using unpaired t test. Result: Within group comparison-Pre-intervention,Post-intervention Mean ±SD of Dizziness Handicap Inventory (DHI) of group A was 37±6.48 and 23.6±8.09 respectively. In DHI there was statistically extremely significant difference with p-0.0003 and t-5.57. Group B pre and post intervention mean±SD of DHI was 38.6±3.27 and 23.6±5 respectively which was statistically not significant with p- 0.0786 and t-1.98. Pre and Post Mean ± SD of MSQ of Group A was 30.82±5.75 and 9.72±4.83 respectively. Post treatment extremely significant improvement was noted according to the p value-<0.0001, t value 16.95 and Group B was 30.62±7.36 and 25.28±7.19 respectively which was statistically not significant with p-0.075 and t- 2.013. Between group comparison-Post intervention mean ±SD DHI was 23.6±8.09 and 35.2±5 respectively which was statistically extremely significant with p-0.0012 and t- 3.85 with decrease in disequilibrium, dizziness and limitations in daily activities. MSQ post intervention mean±SD was 9.72±4.83 and 25.28±7 which was statistically extremely significant with p<0.0001 and t-5.67 with decrease in balance, functional mobility impairments. Conclusion: Activation of deep neck muscles as an adjunct to vestibular rehabilitation in vertigo had significant effect in improving postural stability with balance, functional mobility, reduced impact of symptoms on daily activities. So, this study accepts alternate Hypothesis.
