Total 46 subjects were screened outof which 5 did not fit ininclusion criteria. Then written informed consent was obtainedfrom the participants. Pre training baseline scores were obtained for Motion SicknessAssessment Questionnaire (MSAQ) and Criteria for identifying the severity ofacute motion sickness. Instructions were given to fill the questionnaire on thebasis of road travelling experience. Before starting with the training session,few trials were given to the participants for the visual vestibular habituationexercises and controlled breathing technique. Out of the remaining 41participants 4 were notwilling to participate in the intervention programme and 7 discontinued the treatment on 3rdday of 1st week of intervention.The participants performed the exercises in a well-ventilated, spaciousexercise therapy unit of the physiotherapy department of Pravara RuralHospital. Instructions to turn off theirmobile phones or keep them on silent mode, to maintain silence, to concentrateon the breathing pattern, and to concentrate on visual vestibular exercisesthroughout the session were given to them prior to each intervention.
Participants were told that while doing the exercises they might experiencesymptoms of motion sickness and were also reminded that they could discontinuethe exercise at any time, for any reason (see Table 1 and 2 for Visualvestibular habituation and Controlled breathing Protocol).The total interventional protocol was conducted for 45 min, i.e.
30 minof Visual vestibular habituation exercises and 15 min for controlled breathingtechniques. Intervention was given for 5days per week for 2 weeks under supervision of researcher. Also Homeexercise program was taught which will be twice per week for remaining 8 weeks.To rule out the bias participants were requested to avoid travel during 2 weeksof intervention. The participants demonstrated an ability to safelycomplete stage 1 visual vestibular exercises, step 1 through 5 for 10 sec forfirst two days of intervention without any increase in symptoms along withdiaphragmatic breathing.
Then they were asked to continue the same exercisesfor 30 sec for the remaining 3 days if they experience no increase in symptoms.Those who could not continue the exercises for 30 sec or if they felt increasein symptoms were asked to do the exercises for 10 sec until they felt decreasein symptoms or were instructed to stop if the symptoms were alleviated. Theywere instructed to monitor their reactions to exercises (e.g.
An increase ordecrease in symptoms) and to note them in a daily log book. They were toproceed to stage 2 activities as instructed for the 2 week of intervention whenthey could complete all stage 1 exercises without symptoms. They were asked toperform the exercises for 30 sec, if they experience any severe reactions theywere told to stop the exercises and contact the therapist. Exercises were to beperformed dailyAfter the end of 2 week re-assessment using, the MSAQ questionnaire andseverity of acute motion sickness criteria was done.
