NCT07797530

Brief Summary

The aim of this clinical study is to investigate the effectiveness of breathing training added to a standard physical therapy and exercise program in individuals with non-specific subacute neck pain. Specifically, the study will evaluate the effect of breathing training on functional loss due to neck pain and on respiratory function. The main questions it aims to answer are:

  • Does breathing training reduce functional loss due to neck pain in participants?
  • Does breathing training improve respiratory function in participants?

Outcome Measures

Primary Outcomes (18)

  • Neck Disability

    Neck disability will be assessed using the Neck Disability Index (NDI). The total score ranges from 0 to 50, with higher scores indicating greater disability.

    Change from baseline neck disability at week 6.

  • Forced Expiratory Volume in 1 Second (FEV1)

    Forced expiratory volume in 1 second (FEV1) will be assessed using a COSMED Pony FX spirometer according to ATS/ERS guidelines. FEV1 will be recorded in liters.

    Change From Baseline in FEV1 at Week 6

  • Forced Vital Capacity (FVC)

    Forced vital capacity (FVC) will be assessed using a COSMED Pony FX spirometer according to ATS/ERS guidelines. FVC will be recorded in liters.

    Change from baseline in FVC at week 6

  • FEV1/FVC Ratio

    The FEV1/FVC ratio will be calculated from spirometric measurements obtained using a COSMED Pony FX spirometer according to ATS/ERS guidelines. The FEV1/FVC ratio will be expressed as a percentage.

    Change from baseline in FEV1/FVC ratio at week 6

  • Peak Expiratory Flow Rate (PEFR)

    Peak expiratory flow rate (PEFR) will be assessed using a COSMED Pony FX spirometer according to ATS/ERS guidelines. PEFR will be recorded in liters per minute.

    Change from baseline in PEFR at week 6

  • Slow Vital Capacity (SVC)

    Slow vital capacity (SVC) will be assessed using a COSMED Pony FX spirometer according to ATS/ERS guidelines. SVC will be recorded in liters.

    Change from baseline in SVC at week 6

  • Respiratory Muscle Strength

    Respiratory muscle strength will be assessed using maximal inspiratory pressure (MIP, cmH₂O) and maximal expiratory pressure (MEP, cmH₂O). MIP will be used to assess inspiratory muscle strength, whereas MEP will be used to assess expiratory muscle strength.

    Change from baseline respiratory muscle strength at week 6.

  • Pain Intensity

    Pain intensity will be assessed using the Visual Analog Scale (VAS). The VAS consists of a 10-cm line ranging from 0 (no pain) to 10 (worst imaginable pain). Participants will mark the point that represents their pain intensity, and the score will be recorded in centimeters.

    Change from baseline pain intensity at week 6.

  • Muscle Strength

    Muscle strength will be assessed using Manual Muscle Testing (MMT) according to the Medical Research Council (MRC) scale. Muscle strength is scored from 0 to 5, with higher scores indicating greater muscle strength.

    Change from baseline muscle strength at week 6.

  • Cervical Range of Motion

    Cervical range of motion will be assessed using a Bubble Inclinometer. Cervical flexion, extension, right and left rotation, and right and left lateral flexion will be measured in degrees.

    Change from baseline cervical range of motion at week 6.

  • Cervical Proprioception

    Cervical proprioception will be assessed using the Laser Pointer-Assisted Angle Reproduction Test. Joint position error will be recorded in degrees.

    Change from baseline cervical proprioception at week 6.

  • Cervical Muscle Endurance

    Cervical flexor and extensor muscle endurance will be assessed using neck flexor and extensor endurance tests. The time that participants can maintain the required test position will be measured with a stopwatch and recorded in seconds.

    Change from baseline cervical muscle endurance at week 6.

  • Posture

    Posture will be assessed using the New York Posture Rating Test, which evaluates postural changes in 13 body regions. The total score ranges from 13 to 65, with higher scores indicating better posture.

    Change from baseline posture at week 6.

  • Forward Head Posture

    Forward head posture will be assessed by measuring the craniovertebral angle (CVA), defined as the angle between a horizontal line and the line connecting the midpoint of the tragus of the ear to the C7 spinous process. The angle will be recorded in degrees.

    Change from baseline forward head posture at week 6.

  • Chest Mobility

    Chest mobility will be assessed using the Chest Expansion Test. Chest expansion will be determined as the difference between chest circumference at maximal inspiration and maximal expiration and recorded in centimeters.

    Change from baseline chest mobility at week 6.

  • Anxiety and Depression

    Anxiety and depression will be assessed using the Hospital Anxiety and Depression Scale (HADS). The scale consists of 14 items, with 7 items assessing anxiety and 7 assessing depression. Each subscale ranges from 0 to 21, with higher scores indicating greater symptom severity.

    Change from baseline anxiety and depression at week 6.

  • Quality of Life Assessed by the SF-12

    Quality of life will be assessed using the 12-Item Short Form Health Survey (SF-12). Higher scores indicate better quality of life.

    Change from baseline quality of life at week 6.

  • Insomnia Severity

    Insomnia severity will be assessed using the Insomnia Severity Index (ISI). The ISI consists of 7 items, each scored from 0 to 4. The total score ranges from 0 to 28, with higher scores indicating greater insomnia severity.

    Change from baseline insomnia severity at week 6.

Other: Active Comparator: Progressive Muscle RelaxationOther: Exercise ProgramOther: Traditional Physiotherapy

Interventions

The patient will sit comfortably in a chair in a quiet environment, with shoulders relaxed, and will be instructed to perform deep, slow breathing with prolonged exhalation. The cycle will be: Breathing Control-Thoracic Expansion Exercise (TEE)-Breathing Control-Thoracic Expansion Exercise-Breathing Control-Bilateral Thoracic Expansion Exercise (BTEE)-Breathing Control. Each step will be repeated 3-5 times. During TEE and BTEE, proprioceptive tactile stimulation will be applied by resistance during inhalation. The application procedure will be taught in sessions 1 and 2. At home, the patient will place their own hand where the therapist normally places theirs. The program will be performed 3 days/week for 6 weeks, 15-20 minutes/session. Participants will also be instructed to perform the technique at home twice daily.

Active Cycle of Breathing Technique Group

The patient will wear comfortable clothing and sit in a quiet environment. During Progressive Muscle Relaxation, the eyes will be closed and attention will be focused on the body, particularly on muscle tension and relaxation. The session will begin with deep breathing and relaxing music. During inhalation, each muscle group will be contracted for 5 seconds and relaxed for 10 seconds during exhalation, while other muscles remain relaxed. The technique will be applied in order to the hands, arms, face, neck, shoulders, chest, abdomen, back, hips, thighs, lower legs, and feet. At the end, all muscles will be contracted and relaxed together, and the relaxed position will be maintained for 2 minutes. The program will be performed 3 days/week for 6 weeks, 15-20 minutes/session.Participants will also be instructed to perform the technique at home twice daily.

Progressive Muscle Relaxation Group

The exercise program will include active range of motion (AROM), stretching, scapular stabilization, deep cervical muscle, and postural exercises. During weeks 1-2, the exercises will be performed as 1 set, progressing to 2 sets in week 3. From week 4, resistance will be added to selected exercises as appropriate. These exercises will be performed as 1 set during weeks 4-5 and 2 sets during week 6. The program will be performed under the supervision of a physiotherapist 3 days per week for 6 weeks, for a total of 18 sessions, with each session lasting 15-20 minutes. Participants will also be instructed to perform the exercises at home twice daily.

Active Cycle of Breathing Technique GroupProgressive Muscle Relaxation Group

Traditional physiotherapy will consist of electrotherapy modalities, including hot pack, ultrasound, interferential current, and transcutaneous electrical nerve stimulation (TENS). Traditional physiotherapy will be provided 5 days per week for 3 weeks, with each treatment session lasting 45 minutes.
