About this study

Neck pain is a common musculoskeletal complaint in society. It is the most common musculoskeletal problem after low back pain. It may regress spontaneously within a few weeks or may become chronic, as in 30% of patients. When it becomes chronic, it can negatively affect the daily life activities of individuals and lead to functional limitations and inadequacies.

Various approaches exist for neck pain in clinical practice. Among them; education of patients on neck pain, ergonomic arrangements, analgesics, non-steroidal anti-inflammatory drugs, muscle relaxants, exercise, physical therapy agents such as transcutaneous electrical stimulation (TENS), superficial and deep heaters, Pulse Electromagnetic Field Therapy (PEMT) , manipulation, mobilization methods, nerve blockages and surgical intervention.

Magnetotherapy is a treatment method based on magnetic field interaction. As a result of pulsed or alternating electromagnetic fields, an electrical current occurs in the tissues. Pulse magnetotherapy has three physical mechanisms known to be effective in living tissue: Magnetic induction, magneto-mechanical effects, and electronic interactions. Effects of magnetic field application are vasodilation, analgesic effect, anti-inflammatory effect, acceleration of healing, antiedematous effect. Magnetotherapy increases the oxygen release of erythrocytes and provides oxygenation of the tissues. This causes a decrease in toxins in the damaged area, an increase in vital nutrients and endorphins. With this physiological change, magnetic energy decreases the pain receptor sensitivity that sends a message to the brain. With this treatment method, pain reduction is achieved, while joint mobility increases. This investigation was designed prospective sham controlled randomized study. Participants were randomized into 3 groups: PEMT + therapeutic exercise, sham PEMT + therapeutic exercise, and only therapeutic exercise. As evaluation parameters, cervical range of motion, Visual Pain Scale (VAS) Neck, Visual Pain Scale (VAS) Neck, SF (Short form) -36 Quality of Life Scale, pressure pain threshold measurement with an algometer, patient global assessment, and physician global assessment will be evaluated with.It was planned that the evaluations were made and recorded by a blinded physician to the groups at the beginning of the treatment, at the end of the treatment and at the 6th week controls.

Treatment and study plan

Pulse electromagnetic field therapy

Other

It was applied with an electromagnetic field device (ASA Pmt Quatro Pro, ASA Srl Via A.Volta 9-36057 Italia) at 25 Hz frequency, 30 Gauss, %35 intensity and for 25 minutes. The treatment period was 5 days a week for 3 weeks, in total. It was applied as 15 sessions.

Therapeutic Exercise As a therapeutic exercise program (neck stability exercises); active cervical ROM, cervical isometric and progressive (selfexercise with Thera-Band) strengthening muscles; trapezius, scalene, rhomboid, levator scapular, pectoral, suboccipital muscles stretching exercises, scapular stabilization exercises. It was planned to implement a total of 15 sessions 5 days a week for 3 weeks, for approximately 30 minutes. Exercises will be performed by a trained (at least 5 years experienced) physiotherapist, three times a day, in 3 sets, 10 repetitions.

Sham pulse electromagnetic field therapy

Other

Sham pulse electromagnetic field therapy was applied five sessions a week for four weeks, for a total of 15 sessions a day, using electromagnetic field device (ASA Pmt Quatro Pro, ASA Srl Via A.Volta 9-36057 Italy) without current flowing through the device.

Therapeutic Exercise As a therapeutic exercise program (neck stability exercises); active cervical ROM, cervical isometric and progressive (selfexercise with Thera-Band) strengthening muscles; trapezius, scalene, rhomboid, levator scapular, pectoral, suboccipital muscles stretching exercises, scapular stabilization exercises. It was planned to implement a total of 15 sessions 5 days a week for 3 weeks, for approximately 30 minutes. Exercises will be performed by a trained (at least 5 years experienced) physiotherapist, three times a day, in 3 sets, 10 repetitions.

Primary outcomes

  1. Change from baseline visual analog scale (VAS) neck and arm pain at 3rd and 6th week

    Time frame: up to 6th week

    Pain intensity was measured with visual analogue scale for pain (0-10 mm; 0 means no pain, 10 means severe pain) which is used to measure musculoskeletal pain with very good reliability and validity.

Secondary outcomes

  1. Change from baseline quality of life (short form 36 (SF-36)) at 3rd and 6th weeks

    Time frame: up to 6th week

    This is a self-administered scale, which is widely used to measure the quality of life. It was developed to measure the quality of life in patients who have physical illnesses; however, it can also be successfully used in healthy individuals and patients who have psychiatric diseases. SF-36 includes 36 items and surveys eight domains of health, such as physical functionality, physical role limitations, pain, general health, vitality, social functionality, emotional role limitations, and mental health. Total score was between 0 ( disability) and 100 (no disability). Every subgroup of the questionnaire has a score scale between 0 and 100. Every increase in the subgroup of SF-36 questionnaire, which is a positive scoring system, indicates increase in quality of life related to health.

  2. Change from baseline range of motion of cervical spine measurements with goniometer at 3rd and 6th weeks

    Time frame: up to 6th week

    Cervical flexion, extension ,lateral flexion ,rotations(goniometric measurement results in units of degrees).

  3. Change from baseline Neck Dısabılıty Index (NDI) at 3rd and 6th weeks

    Time frame: up to 6th week

    The Neck Disability Index (NDI) is designed to measure neck-specific disability. The questionnaire has 10 items concerning pain and activities of daily living including personal care, lifting, reading, headaches, concentration, work status, driving, sleeping and recreation. Each question measures from 0 to 5, the total score out of 100 is calculated.

  4. Change from baseline Pressure pain threshold measurement with an algometer at 3rd and 6th weeks

    Time frame: up to 6th week

    The algometer is a useful tool for determining pressure pain threshold measurements. Pressure pain threshold is defined as the minimum force applied to elicit pain. A digital pressure algometer (Baseline, push-pull, force gauce Algometer, USA) will be used for measurements. The most painful point in the cervical region will be determined by sitting all patients in their most comfortable position for measurement. Three measurements will be made at an angle of 90 to this point, repeated at 1-minute intervals, and the average of these three measurements will be taken and this value will be recorded as the mean pressure pain threshold in kg/cm2. During the measurement, the value at the first moment when the patient feels pain will be taken as a basis.

  5. Change from baseline In the global evaluation of the patient at 3rd and 6th weeks

    Time frame: up to 6th week

    "Very bad" is written on the end corresponding to the numerical value of "0 cm" and "very good" is written on the end corresponding to the numerical value of "10 cm".

  6. Change from baseline In the doctor's global evaluation at 3rd and 6th weeks

    Time frame: up to 6th week

    "Very bad" is written on the end corresponding to the numerical value of "0 cm" and "very good" is written on the end corresponding to the numerical value of "10 cm".
