Conventionally used intervention for subacute and chronic neck pain.

The Numeric pain rating scale (NPRS) is a self-reported, or clinician-administered, measurement tool consisting of a numerical point scale with extreme anchors of 'no pain' to 'extreme pain. The scale is typically set up on a horizontal or vertical line, ranges most commonly from 0-10 or 0-100, and can be administered in written or verbal form. The patient is asked to rate his/her pain intensity and a particular time frame or descriptor is established (e.g. within the last 24 h, today, worst pain, average pain, or least pain). The NPRS scores are high on ease of administration and simplicity for scoring. The last reading will be taken when the NPRS score will be less than 3.

The Neck Disability Index (NDI) is a 10-item questionnaire that measures a patient's self-reported neck pain-related disability. The NDI is the most widely used, translated and oldest questionnaire for neck pain. Questions include activities of daily living, such as personal care, lifting, reading, work, driving, sleeping, recreational activities, pain intensity, concentration and headache. Each question is measured on a scale from 0 (no disability) to 5, and an overall score out of 100 is calculated by adding each item score together and multiplying it by two. A higher NDI score means the greater a patient's perceived disability due to neck pain. The "minimally clinically important change" by patients has been found to be 5 or 10%. The last reading will be taken when the NPRS score will be less than 3.

Goniometric measurements are used by physical therapists to quantify baseline limitations of motion, decide on appropriate therapeutic interventions, and document the effectiveness of these interventions. Goniometry can be considered a fundamental part of the "basic science" of physical therapy. To most physical therapists, however, the universal goniometer (i.e. full-circle manual goniometer) remains the most versatile and widely used instrument in clinical practice. The last reading will be taken when the NPRS score will be less than 3.

The Pain Anxiety symptom scale -20 (PASS-20) was constructed by extracting 20 items from its 40-item parent measure Pain Anxiety symptom scale (PASS) (18). The PASS-20 is a 20-item self-report instrument, measuring 4 factorially distinct components of pain-related anxiety. The cognitive subscale assesses cognitive anxiety symptoms, such as racing thoughts and impaired concentration due to pain. The fear subscale assesses fearful thoughts and anticipated negative consequences of pain. The escape/avoidance subscale assesses behavioural responses that reduce or terminate pain. The physiological anxiety subscale assesses physiological arousal in response to pain. Each item is rated on a 6-point Likert scale ranging from 0 (never) to 5 (always). Summing each subscale provides a score that can be considered a general measure of pain-related anxiety. The last reading will be taken when the NPRS score will be less than 3.
