Insertion of filiform needles into cervicothoracic multifidi, upper trapezius, and suboccipital muscles

One variable to be assessed to determine feasibility is retention rate of participants recruited and enrolled. The retention rate of participants will be calculated as follows: Retention rate = (Number of patients completing the study / Number of patients initially enrolled) x 100. Feasibility will be determined with 4-week attrition rate is less than 20%

One variable to be assessed to determine feasibility is intervention adherence. Adherence to therapeutic exercise program given to all participants will be assessed with an exercise diary to be completed by the participants to track exercise compliance. A new diary will be provided on a weekly basis to maintenance of records.

Occurrence of adverse responses to treatment will be accounted for at each subsequent visit after initial treatment administered (visits 3-6). Patients will be asked to complete an intake form that will inquire about their experience post-intervention and provide examples of common adverse responses to determine if such events occurred for each respective participant.

Total sleep time and Sleep latency via wrist actigraphy

Sleep quality will be measured with the use of the Pittsburgh Sleep Quality Index (PSQI). There are seven components that range in scores of 0-3. Total scores range from 0-21 with higher scores indicating worse sleep quality.

Disability level will be measured with the Neck Pain Disability Index (NDI). There are ten questions with a range of scores of 0-5. Total possible scores range from 0-50 or 0%-100% with higher scores indicating greater disability level.
