About this study

Official title: Therapeutic Benefit of Two Modalities TENS and Ultrasound Along With Exercises in the Management of Mechanical Neck Pain; A Randomized Clinical Trial

This randomized clinical trial aims to compare the effectiveness of Transcutaneous Electrical Nerve Stimulation (TENS) and therapeutic ultrasound, both combined with therapeutic exercises, in the management of mechanical neck pain.

A total of 44 participants male and female both with mechanical neck pain will be randomly allocated into two equal groups at the physiotherapy OPD of DOW Institute of Physical Medicine \& Rehabilitation, Dow University of Health Sciences, Karachi. Group A will receive TENS with exercise, while group B will receive ultrasound with the same exercise protocol.

Both groups will receive 9 treatment sessions over 2 weeks. Outcomes will include pain intensity, functional disability, and cervical range of motion, assessed before and after the intervention.

Read the detailed description

Mechanical Neck Pain is described as immediate or prolonged discomfort in cervical and shoulder regions, starting from the base of skull to the spine of scapula, this discomfort may extend down the arms and leading to reduction in the range of motion in the neck region and it occurred without any prior history of trauma, infection or systematic issues like fractures. Nonspecific neck pain is because of postural and mechanical reasons also known as Mechanical Neck Pain. Neck problems are not dangerous but these issues may cause discomfort and firmness. Much of the time neck pain is because of poor posture and flawed ergonomics at work area. Across various countries including Pakistan, Australia, the USA (New York), China, Brazil, and Central Saudi Arabia studies have identified neck pain prevalence among medical students ranging from 8.23% to 65%. Neck pain prevalence most commonly increases with age and greater among women as compared to men. According to studies 30%, 43% men and women respectively once in their lifetime experience neck pain, out of them10% men and 17% women experience chronic pain. Studies reported the 2nd most common musculoskeletal cause of disability globally. It is estimated that there are approximately 12 cases of Mechanical Neck Pain (MNP) per 1000 individuals seeking medical attention per year. Neck pain is a most frequent reason to seek medical attention from healthcare providers. Across the general population, neck pain affects 14% to 71% adults at various stages in their lives, among north Europeans 1-year greater prevalence as compared to Asian population. In general, worldwide population, 25% women and 16% men in Sweden experience neck pain annually. Iran reported 15% prevalence of neck pain in adults. While the exact cause of neck pain remains unclear, it is widely recognized as having a miscellaneous origin. Research indicates a strong correlation with factors such as depression, anxiety, migraines, sedentary lifestyle, disrupted sleep patterns, and smoking. The rising interest in neck pain because of its global prevalence which is 4.9%. Neck pain holds the 4th positions among condition causing disability when assessed in terms of years lived with some sort of pain and disability. Neck pain is responsible for causing disabilities of various severities and major cause of substantial medical expenses, productivity losses and economic burden.

Methodology:

Participants who are diagnose and referred to the Physiotherapy Outpatient Department (OPD) of the DOW Institute of Physical Medicine \& Rehabilitation at Dow University of Health Sciences, OJHA Campus, will be included in the study. All eligible participants will be thoroughly informed about the study through a structured Informed Consent Form. The researcher will introduce herself, explain the purpose, procedures, potential risks, and benefits of the study.

Participants will be allowed ample time to read the form, ask questions, and clarify any doubts. Those willing to participate will be asked to sign the consent form or provide a thumb impression. The screening and initial identification of eligible participants will be supervised by a senior physiotherapist. The informed consent process ensures compliance with ethical principles including autonomy, confidentiality, and the right to withdraw at any stage of the study without any penalty or impact on their ongoing care.

Sample size of 44 participants will be divided into two equal groups through simple random sampling technique through number generator table to ensure each participant has an equal chance of being selected and reduce selection biasness. The method used in the study comprise single blinded methodology.

Group A include 22 participants both male and females, will receive TENS (15 min), heating pad (10 min), followed by cervical active stretching (~4 min) and isometric exercises (~3 min), making a treatment subtotal of ~30 minutes, with the remaining time used for supervision, education, rest, and documentation (total 45 min/session).

Group B also include 22 participants, will receive therapeutic Ultrasound (10 min), heating pad (10 min), the same stretching (~4 min) and isometric exercises (~3 min), totaling ~27 minutes of treatment plus ~15 minutes for supervision and documentation (45 min/session).

Both groups will undergo 9 sessions over 2 weeks (6 consecutive sessions in week 1 and 3 alternate-day sessions in week 2).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Visual Analog Scale (VAS) for Pain

    Visual Analog Scale (VAS) for Pain: Scores range from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate worse pain.

    Measured: Baseline and after 2 weeks of treatment.

Secondary outcomes (3)
  1. Muscle strength measured using Manual Muscle Testing (MMT)

    Manual Muscle Testing (MMT) grades muscle strength on a 0 to 5 scale, where 0 indicates no visible or palpable muscle contraction and 5 indicates normal muscle strength against full resistance. Higher scores indicate better muscle strength.

    Measured: Baseline and after 2 weeks of treatment.

  2. Pressure pain threshold measured using an algometer

    Pressure Pain Threshold (PPT) is measured using an algometer and recorded in Newtons (N). The pressure pain threshold is the amount of force at which pressure first becomes painful. Higher values indicate a higher pressure pain threshold (better outcome/less pain sensitivity).

    Measured: Baseline and after 2 weeks of treatment.

  3. Neck disability measured using the Neck Disability Index (NDI)

    The Neck Disability Index (NDI) scores range from 0 to 50, where higher scores indicate greater neck disability (worse outcome).

    Measured: Baseline and after 2 weeks of treatment.
