Participants were advised to repeat the brochure-based exercises 3 days a week for 8 weeks. Correct sitting and standing positions and ergonomic materials were also explained in detail. Participants' adherence to the exercise program was tracked by an exercise diary.

Progressive physical fitness and posture exercises were given via telerehabilitation 3 days a week for 8 weeks. Specific exercises for upper extremities, lower extremities, neck, trunk and lower back were selected and progressed by changing the frequency, duration and variety within the program. All exercises were performed under the supervision of a physiotherapist during video conference calls lasting an average of 40 minutes. Correct sitting and standing positions and ergonomic materials were also explained in detail. Participants' adherence to the exercise program was tracked by an exercise diary.

Simple posture exercises

The pain was assessed with the 10-cm VAS. The participants used the VAS to make an assessment of their own pain, with 0 representing no pain, and 10 cm representing severe pain.

The fine motor skill was assessed with the 9-Hole Peg Test. It is a simple, fast test that requires minimal space and equipment and evaluates fine upper motor function. In this test, the patient is asked to insert the pegs into the holes in the desired order and collect them back. The duration of the test is measured by a specialist via a stopwatch.

Posture was assessed with the PostureZone Posture Application. The PostureZone mobile application, which can be downloaded free of charge on both Android and iOS via smartphone, will be used to evaluate the static postures of the participants. It is an application developed for clinicians that assess static posture. The participant is photographed with minimal clothing on, certain pivot points are marked, and the deviations of these points relative to the vertical-horizontal planes are determined.

Hand Reaction was assessed with the Nelson Hand Reaction Test. The participant sits on a chair with his forearm and hand in a comfortable position on the table. The tester holds the end of the ruler. The participant is asked to catch the ruler. Twenty rials are performed. The lowest 5 and highest 5 attempts are discarded and the average of the remaining 10 attempts is recorded as the result.

Jamar Hydraulic Hand Dynanometer was used to assess handgrip strength. Each trial was repeated three times and the average was recorded in kilograms
