Neck pain is one of the most common and costly musculoskeletal disorders in western societies with a high rate of recurrence and chronicity. In chronic neck pain, the persistence of symptoms is highly associated with changes in the biomechanics of the neck region that are related to the muscular imbalance between the neck muscles and specifically between the deep and superficial neck flexors. Manual techniques are special techniques applied by hand from the therapist that focus on reducing symptoms and improving disability. Both spinal manipulation and soft tissue mobilization techniques have a positive effect in individuals with chronic neck pain, especially when they are combined with the appropriate therapeutic exercise programme. However, it has not been determined which of the above-mentioned combinations is more effective in patients with chronic neck pain.
The aim of this study is to compare the efficacy of two different kinds of manual technique, when they combine with the same therapeutic exercise program in the management of patients with chronic neck pain.
An assessor-blind randomized control trial with a duration of ten weeks and a 6-month follow up will be performed in 80 women with chronic neck pain. The participants will be allocated into four groups of 20 persons each (three intervention groups and one control group). The first three groups will follow the same exercise program. Only exercise will be applied to the first group. The second group will apply a combination of soft tissue mobilization techniques and exercise. The third group will follow a combination of spinal manipulation and exercise, while the fourth group will not receive any treatment. The neck pain will be evaluated with the visual analogue scale, the disability related to neck pain with the neck disability index, the pressure pain threshold of the neck muscles with pressure algometry, the active range of motion with a bubble inclinometer, the maximum isometric strength of the neck muscles with a hand dynamometer, the muscular fatigue of the flexors of the neck with the craniocervical flexion test and the quality of life with the sf-36 questionnaire before, during and after the intervention, while follow-ups will take place six months later.

| Intervention 1 Exercise | Other | • Exercise programme Endurance and Resistant training exercise program (Duration: 45 minutes) • Muscle retraining of longus colli and endurance training of the deep cervical flexors. • Resistant exercises for the muscles involved in neck flexion, extension, side bending and rotation of the neck region. Isometric contractions exercises (20-70% of MVC) and resistant exercises (12-15RM). • Active ROM exercises for the neck muscles • Upper limbs exercises with resistant bands • Stretching exercises for the neck and upper limbs muscles |
| Measure | Description | Time Frame |

| Changes in neck pain intensity with visual analogue scale (VAS) | VAS is a card with an uncalibrated scale ranging from 0-100 mm on the one side (with zero representing no pain and 100 representing the worst pain in life) with each millimeter representing one pain level. The patient subjectively estimated his or her pain level by marking a vertical line on the uncalibrated scale between zero and one hundred. Then the exact value of pain intensity could be obtained with a single ruler. Hence, the higher the value, the more intense the pain. VAS is widely used as it is easy to implement and is characterized by good psychometric properties. | pre-treatment, Week: 2, 4, 6,10, 34 |
| Changes in Pressure Pain threshold with pressure algometry | Pressure pain threshold (PPT) is defined as the minimal amount of pressure that produces pain. PPT was assessed by a digital algometer. Pressure pain threshold was assessed over the upper border of the trapezius muscle halfway between the midline and the lateral border of the acromion, the levator scapulae muscle 2 cm above the lower insertion located in the upper medial border of the scapulae, Sternocleidomastoid muscle and to splenius capitis 2 cm lateral to the spinous processus of the axis. The metal rod of the algometer was placed vertically on the site and the examiner applied gradually increasing pressure at a rate of 1Kg/s. PPT was calculated in kg/cm2. | pre-treatment, Week: 2, 4, 6, 10, 34 |
| Changes in functional capacity with the Greek Version of Neck disability index questionnaire | It is a self-reported ten-item scale. Each item assesses different neck pain complaints. Most of the items are related to restrictions in activities of daily living, and each item is expressed by 6 different assertions in the range 0-5, with 0 indicating no disability and 5 indicating the highest disability. The total score ranges from 0 to 50. Disability Index (NDI) has sufficient support in the literature, being the most commonly used to report neck pain. | pre-treatment, Week 6, 10, 34 |
| Changes in maximum isometric strength of neck muscles with Manual Muscular Testing |

Cervical flexion, extension, and side bending isometric strength were assessed using a Manual Muscular Testing device with the participants in supine and prone position. Isometric strength were assessed in kg. |
| pre-treatment, Week: 2, 4, 6, 10, 34 |
| Changes in Cervical Range of Motion with bubble inclinometers | Cervical active range of motion was measured with 2 bubble inclinometers. One was placed on the top of the head and the second on the spinous process of C7.Active cervical flexion, extension and side bending range of motion were assessed with participants sitting in upright position. Range of motion was measured in degrees | pre-treatment, Week: 2, 4, 6, 10, 34 |
| Changes in deep flexors muscle endurance with craniocervical flexion test | The craniocervical flexion test (CCFT) is a clinical test of the anatomical action of the deep cervical flexor muscles, (longus capitis, and longus colli). It could be described as a test of neuromotor control. It includes the performance of five progressive stages of increasing craniocervical flexion range of motion (22, 24, 26, 28, and 30 mm Hg). It is a low-load test performed in the supine position with the patient guided to each stage by feedback from a pressure sensor placed behind the neck. While the test in the clinical setting provides only an indirect measure of performance. | pre-treatment, Week: 2, 4, 6, 10, 34 |
| Changes in quality of life with the sort form of SF-36 Health Survey | For the evaluation of the intervention in the quality of life of the participants the short form of SF-36 Health Survey questionnaire was used. SF-36 consists of 36 questions, selected from the Medical Outcomes Study (MOS), which relate to eight different parameters of mental and physical health. Total Physical and Mental Health, as well as the subcategory of Bodily Pain were evaluated in this study | pre-treatment, Week: 10, 34 |
