Official title: The Effects of Manual Therapy Applied to the Cervical Region on Balance and Proprioception in Patients With Nonspesific Neck Pain: A Randomised Placebo Controlled Study
Introduction: Neck pain causes disturbances in both proprioception and balance. The aim of the present study is to determine the effect of mobilization applied to the cervical region on static/dynamic balance and cervical proprioception in patients with nonspecific neck pain (NSNP).
Materials and Methods: ... patients were randomly allovated into two groups. Both grups received conventional physiotherapy program (hot pack with transcutaneous electrical nerve stimulation); additionally, the experimental group received mobilization, and the control group received placebo mobilization twice a week for 3 weeks. Before and 3 weeks later, static/dynamic balance, cervical proprioception, cervical mobility and pain were evaluated respectively with Kinesthetic Skill Training System 3000 device, joint position error test, Cervical Joint Range of Motion Device, Visual Analogue Scale.
Read the detailed description
Nonspecific neck pain (NSNP) is one of the most common causes of neck pain and it occurs as a result of postural or mechanical causes without a specific musculoskeletal pathology or injury history. Neck pain leads to a decrease in the activity of the deep cervical muscle which contains a large amount of muscle spindles, with an increase in the activity of the superficial cervical muscle. Depending on the pain, chemical changes occur in the cervical receptors and differentiation in sensitivity of the muscle spindle is observed. These changes in the structures of the cervical region predispose to deterioration in the sense of proprioception, which is an important component of balance. The disruption in proprioceptive abilities causes sensori-motor defects, muscle inhibition, muscle atrophy, and muscle fatigue. Changing cervical afferent information can affect proprioception as well as balance. Both the presence of neck pain and disruptions in the proprioceptive sense may reflect negatively on balance and postural control. In a study comparing patients with neck pain with asymptomatic individuals, increases in postural sway were found in patients with neck pain, and it was stated that the increased sway was associated with the dysfunction of the postural control system.
In the light of these informations, treatment approaches that can positively contribute to proprioception and balance gain importance in patients with NSNP. Although manual therapy is used both to reduce pain, and to increase cervical mobility in patients with NSNP, the number of studies investigating the effects of manual therapy on balance and proprioception is quite insufficient.
It was thought that mobilization applied to the cervical region can improve cervical proprioception and mobility, reduce pain and contribute positively to balance. The purpose of this study is to examine the effect of mobilization applications on the balance and cervical proprioception in patients with NSNP.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Cervical mobilizationOther
Also called Manual therapy
A kind of manual therapy tecnique applied to the cervical region
Placebo mobilizationOther
It was applied to the randomly selected cervical faset without any pushing or pulling in the same position and the same grip with cervical mobilization.
| Study group | Role | What they receive |
|---|---|---|
| cervical mobilization | Experimental | 'Rotation mobilization' was applied to the symptomatic segment / segments after the detailed evaluation (symptom localization tests, cervical region safety tests, joint play tests, pain provocation/alleviation tests) in accordance with the Kaltenborn-Evjenth system in cervical region. Five series of 45-s mobilizations were performed with 15 s of rest. Each patient received 6 treatment sessions over a period of 3 week. Receives: Other: Cervical mobilization |
| placebo mobilization | Placebo comparator | Placebo mobilization was applied to the cervical region in the same position and the same grip with the mobilization group. The physiotherapist put her hand on a randomly selected faset without any pushing or pulling, The duration of placebo mobilization was the same as the duration of the other group. Each patient received 6 treatment sessions over a period of 3 week. Receives: Other: Placebo mobilization |
What is being measured
The primary outcome is the main question the study is designed to answer.
Balance
Balance measured with the Kinesthetic Ability Training System 3000 (Med-Fit Systems Inc., Fallbrook, C.A., USA) for static and dynamic balance. The increase in the balance index indicates a deterioration in balance, while the decrease in the index represents an improvement in stability.
Measured: baseline-3rd week
Cervical proprioception
Cervical joint position error test was conducted using the CROM device in transverse plane (right and left rotation). A travel eye mask was used to blindfold the patient. The examiner held the patient's head and moved slowly to the target head position, which is 50% of the maximum cervical range of motion. When patient reached actively the target position that memorized, the difference between the target position and the position obtained was recorded. Each direction of testing was performed three times and the mean error of these trials was used in the analysis.
Measured: baseline-3rd week
Secondary outcomes (2)
Cervical mobility
Active cervical range of motion was measured with the CROM device (Cervical Range of Motion-Perfomance Attainment Associates, St. Paul, MN, 55117, United States) for each direction (flexion, extension, right and left lateral flexion, right and left rotation). It is an inclinometer system that utilizes gravity and magnetic effects.
Measured: baseline-3rd week
Cervical pain
The visual analog scale (VAS) was used to assess patient's pain intensity.
Measured: baseline-3rd week

Questions about this trial
What is this clinical trial studying?
A study testing Cervical mobilization in people with Neck Pain, run by Gazi University at 3 sites in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 31 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Balance (time frame: baseline-3rd week). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04794647, which also lists 17 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Oct 2023.
