Effects of a Mobile App on Adherence to Daily Exercise and Recovery After Whiplash Injury

Effects of a Mobile App on Adherence to Daily Exercise and Recovery After Whiplash Injury - a Randomized Controlled Trial

This study investigates the effect of daily mobile app reminders to exercise in conjunction with standard physical therapy on adherence to exercise and recovery after whiplash injury of the neck. Participants will be divided into two groups, the experimental (Arm A) and control group (Arm B). Both groups will complete a standard physical therapy program under the supervision of a physiotherapist. Both groups will get illustrated home exercise programs and will be advised to continue exercising at home. In addition, the experimental group will receive one daily push notification via a mobile app to perform a daily exercise at home.

Study Overview

• Status: Recruiting
• Conditions: Whiplash Injury of Cervical Spine
• Intervention / Treatment: Behavioral: Reminder to exercise

Detailed Description

Whiplash injury of the neck is the most common injury resulting from a traffic accident. Although most people recover completely, 30 to 50% of them develop chronic neck pain and disability. Also, long sick leaves and lower productivity at work create a burden on the healthcare system.

Conservative treatment includes exercise, physical therapy modalities such as transcutaneous electric nerve stimulation (TENS), and ultrasound therapy. Although conservative treatment is recommended, the evidence of its efficacy remains unclear. Education after the injury can be beneficial in lowering anxiety and pain.

Many studies are investigating the usefulness of mobile apps in various medical conditions. In rehabilitation medicine, apps are used to increase knowledge about different conditions, as a measurement tool, and as an intervention to increase adherence to the prescribed therapy.

After the enrollment in the study, participants will complete the two-part physical therapy program (2x10 sessions, 5times/day, 3-week break in between) under the supervision of a physiotherapist at the outpatient clinic. After completing the program, the participants will get a home exercise program, group A via mobile app, and group B via papers, and will be encouraged to continue exercising at home. Also, group A will download a mobile app, "WIapp," that was developed for this purpose and will receive one daily push notification as a reminder to perform a daily exercise at home.

The investigators hypothesize that daily reminding to exercise via mobile app can increase adherence to prescribed therapy and overall increase recovery.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Mobile app (WIapp) group; Standard physical therapy program: 2x10 sessions, 5 times a week, 3-week break in between; Mobile app with instructions on exercise at home and daily reminder to exercixse	Behavioral: Reminder to exercise; Exercise support: Daily, at 7 p.m. patients will get a notification with a reminder to exercise. The app includes photographs of exercises, with instructions, that patients can look at and read if they forget which exercises they need to do and how.
No Intervention: Control group; Standard physical therapy program: 2x10 sessions, 5 times a week, 3-week break in between, written instructions on exercises at home

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Neck Disability Index from baseline to 6 months after the injury	Physical functioning - where values from 0-8% are regarded as no disability, 10-28% mild disability, 30-48% as moderate disability, 50-68% severe disability, and 70-100% complete disability)	baseline, 6 months after the injury

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Questionnaire assessment of adherence to exercise	Adherence to exercise - a 4-point Likert scale regarding weekly exercise completion (classified as: ≥5 sessions/week, 2-4 sessions/week, occasional or no sessions)	6 months after the injury
Questionnaire assessment of perceived recovery	Perceived recovery - a 3-point Likert scale on perceived recovery (where 1 indicates non-recovery and 3 indicates full recovery)	6-months after the injury
Change in Visual Analog Scale (VAS) Pain Score from baseline to 6 months after the injury	Pain intensity - ranging from 0 = no pain, to 10 = maximum pain	baseline, 6 months after the injury
Pain catastrophizing scale	Psychological functioning - (score range from 0-50, a score of 30 or more represents clinically significant level of catastropihizing)	baseline
Short Form Health Survey 12	Quality of life - With this questionnaire, it is possible to quantitatively compare physical, psychological, and social consequences caused by impaired health. The score for each question is transformed into standard values and placed on the scale from 0 to 100 (the higher the score the better health) and thus get two major dimensions of health: physical (Physical Common Score-PCS)and mental health (Mental Common Score-MCS).	baseline
Questionnaire assessment of social functioning	A 5-point Likert scale regarding interference of physical or emotional problems with social function (where 1 indicates constant interference and 5 indicates never)	baseline
Questionnaire assessment work	The assessment of work with a work status information, a work-time loss and 6-point Likert scale (where 1 indicates normal work capability and 6 indicates no working capability9	baseline, 6 months after the injury
Pain catastrophizing scale	Psychological functioning - (score range from 0-50, a score of 30 or more represents clinically significant level of catastropihizing)	6 months after the injury
Short Form Health Survey 12	Quality of life - With this questionnaire, it is possible to quantitatively compare physical, psychological, and social consequences caused by impaired health.
