Design: This study is a pilot randomized controlled trial (RCT) with two-arm parallel groups, the gold standard for determining treatment efficacy. The flowchart (see appendix) provides an overview of the study design. Participants are randomized and stratified by age into intervention group and waiting list group.

The intervention is teletherapy-supported muscular training for 20 minutes 4 times a week.

The duration of the intervention is six weeks in total. At the beginning Neck Disability Index (NDI), Oswestry Disability Index (ODI), Short-Form-36 (SF36), and the Numerical rating Scale (NRS) are collected. After six weeks, the same outcome measures and the global rating scale

Intervention of interest: As already mentioned, the protocol of interest is an exercise program supported by online sessions (teletherapy). Exercise routines related to the individual areas of the spine as a functional unit were created based on evidence-based conclusions, especially considering muscle chain activity and appropriate loading parameters

The teletherapy exercise program is carried out once a week via ZOOM by a physiotherapist with thirty years of experience in treating patients with musculoskeletal disorders. Participants are also encouraged to carry out this exercise program themselves at home three times a week so that they have four sessions per week for six weeks. The duration of each session is approximately twenty minutes per session. There are six exercises with three sets and about fifteen repetitions within thirty seconds per set. Exercise description with rationale for exercise selection"). Subjects in the treatment group will also receive a video, rhythm and music files and written materials to help them follow the exercise routines at home, as well as a rubber band. Subjects are also asked to keep a diary in which they record their adherence to the home treatment protocol.

At the beginning of the intervention and after the seventh week, the participants are each assessed with the Patient Reported Outcomes (PROMs), namely ODI, NDI and SF36 short and NRS 11-point scales. At the end of the intervention, participants are interviewed using the Global Rating Scale. Below is a brief description of these instruments.

Control group:

Subjects in the control group will be advised to maintain their daily routine but will be asked to refrain from other treatments such as physical Therapy (PT), osteopathy, chiropractic as well as other therapeutic exercise (TE) therapies to avoid co-interventions during the 6-week study period. However, pain medication taken by study participants for more than 3 months in all groups, such as non-steroidal anti-inflammatory analgesics (NSAIDs), will be permitted and documented (taking a pragmatic approach). Any change in medication will be monitored and recorded by the PT at each visit.
