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.
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.

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 |
