Headache SNAG: A posteroanterior mobilization of the second cervical vertebrae is maintained for 10-30 seconds having the patient comfortably seated on a chair or couch. A maximum of six repetitions were administered. The patient is administered SNAG mobilization by placing the medial border of the thumb's distal phalanx on the spine of one vertebra above while standing behind the patient. The thumb tips were positioned at a 45° angle, and another thumb is used to provide the glides. Glides are performed in 3 sets and 6 times during the session.

Reverse Headache SNAG: Anterio-posterior mobilization of the second cervical vertebrae is maintained for 10-30 seconds having the patient comfortably seated on a chair or couch. A maximum of 6 repetitions were administered.

The NRS is used to gauge the patient's degree of pain. On a 0-10 scale, where 0 represents no pain, 1-3 represents mild pain, 4-6 represents moderate pain, and 7-10 represents severe pain, this tool is frequently used to gauge the intensity of pain. Patients rate how much pain they are currently experiencing as well as how much pain they have experienced in the past 24 hours.

This questionnaire is used to evaluate migraine patient's quality of life. The 14-item MSQ version 2.1 measures QOL impacts in three domains: Role function-restrictive (RFR), which measures the functional impact of migraine through limitations on daily social and work activities; Role function-preventive (RFP), which measures the impact of migraine through prevention of daily work and social activities; and Emotional function (EF), which measures the emotional impact of migraine through three items. The raw total score was the sum of all item scores, which were rescaled from 0 to 100, with a higher score denoting better quality of life. Raw scores in each domain were calculated as the sum of all item scores.

The Migraine Disability Assessment Scale (MIDAS) is intended to assist individuals and medical professionals in comprehending how migraines affect day-to-day living. MIDAS gives a more accurate view of the overall impact of migraines by evaluating how frequently they occur and how they interfere with social activities, employment, and domestic duties. It is simpler to customize therapy to meet each patient's needs when the information is used to determine treatment choices and monitor progress overtime. In the end, it's a tool that facilitates improved communication and assistance in migraine management by allowing patients to share their experiences and difficulties.
