A 10-minute video consisted of 14 exercises was uploaded to the computers of the participants in the exercise group. Participants were asked to do these exercises simultaneously with the video, 3 days in a week for 6 weeks. During theese weeks, the participants were checked by sms and they were asked to keep an exercise diary. For progression, the number of repetitions was increased in the 3rd week and the number of sets in the 5th week.

The control group was given one session of training on postural correction.

A 10-minute video consisted of 14 cervical and thoracal postural exercises was uploaded to the computers of the participants. Participants were asked to do these exercises simultaneously with the video, 3 days in a week for 6 weeks. During theese weeks, the participants were checked by sms and they were asked to keep an exercise diary.

The cervical and scapular muscle strength was meausured with a Hand Held dynamometer (Lafayette Manual Muscle Test System™/ Model 01163-Lafayette Instrument Company, Lafayette, Indiana). Measurements were repeated three times, the average value was recorded.

The muscular endurance of the deep cervical flexors was evaluated with the cranio-cervical flexion test. For general cervical flexor muscles, 0.5 kg weight was placed on the cervical region of the participant. The participant was asked to perform 10° cervical flexion while in cervical retraction, and the time he/she maintained this position was recorded. And for the trapezius and serratus anterior muscles, Scapular muscular endurance test was used.

The QoL was assessed with the Short Form-36 QoL questionnaire administered under the supervision of the investigator. The SF-36 measures eight scales: physical functioning (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role emotional (RE), and mental health (MH). A score of zero indicates poor health, and a score of 100 indicates good health.
