Effectiveness of a Training Protocol With the Cervical Device in Subjects With Deep Cervical Muscle Strength Deficit.

June 17, 2025 updated by: Pilar Pardos Aguilella, Universitat Internacional de Catalunya

Effectiveness of a Training Protocol With the Cervical Device in Subjects With Deep Cervical Muscle Strength Deficit in Cervical Range of Motion, Muscle Endurance and Neck Disability.

The purpose of this study is to evaluate the clinical results produced by a training protocol with the new device for cervical treatment (CDAT) and the conventional training protocol (CT) versus a control group (C) in subjects with cervical deep muscle strength deficit and mild neck disability.

Study Overview

Detailed Description

Cervical pain is in many cases a decrease in the quality of life.The cervical spine is the most mobile region of the spine which also must be strong enough in order to support the weight of the skull. Deficits in deep cervical muscle strength are related to different clinical conditions: cervicogenic dizziness, cervical radiculopathy, cervical mechanical-chronic, cervical pain and cervical instability. Training protocols can help to improve pain, cervical function, posture and cross-sectional area. However, there are no training protocols in subjects with mild disability and strength deficit of the deep cervical muscle, including deep neck extensor and flexor muscles. The cervical device treatment (CDAT) allows us to train the cervical flexor and extensor muscle in a simple and comfortable way.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Neck Disability Index
Time Frame: Baseline and 6 weeks, 10 weeks, 14 weeks

Mean change from baseline in Neck Disability Index (NDI) (Neck Function) after 6 weeks , 10 weeks and 14 weeks.

The examiners assess the self-perceived disability from neck pain using the NDI. 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. The measure is designed to be given to the patient to complete.

Item scores range from 0 (no disability) to 5 (total disability), with the minimum score is 0 (no disability) and maximum score of 50 (complete disability).

Baseline and 6 weeks, 10 weeks, 14 weeks
Craniocervical flexion test
Time Frame: Baseline and 6 weeks, 10 weeks, 14 weeks
The examiners assess the strength of deep cervical flexors with craniocervical flexion test.
Baseline and 6 weeks, 10 weeks, 14 weeks
Cervical Spine range of motion
Time Frame: Baseline and 6 weeks, 10 weeks, 14 weeks

Mean change from baseline in Lower and Upper Cervical Spine Range of Movement (ROM) after 6 weeks , 10 weeks and 14 weeks.

The examiners assess the cervical ROM using CROM (Cervical Range-of-Motion Instrument). Cervical flexion, extension, right/left sidebending, right/left rotation will be evaluated.

The examiners assess the cervical ROM using CROM (Cervical Range-of-Motion Instrument). Upper cervical flexion, upper cervical extension and flexion rotation test will be evaluated. Flexion rotation test is used to see the amount of movement of the upper cervical spine and is the test most used in the literature. It is positive when there is a decrease of 10 degrees or more in the cervical rotation with maximum flexion, in a sense with respect to the contralateral or presents hypomobility of segment C1 with a mobility less than 32.

Baseline and 6 weeks, 10 weeks, 14 weeks
GLOBAL RATING OF CHANGE SCALE (GROC)
Time Frame: Baseline and 6 weeks, 10 weeks, 14 weeks

The examiners assess self-perceived improvement in a patient and has been used as an anchor method to determine minimal clinically important change scores after 6 weeks, 10 weeks and 14 weeks. The GROC is a single-item, recall-based questionnaire of well-being that is based on progress (or lack of progress) since an initial treatment encounter.

Item scores range from - 7 (A very great deal worse) to + 7 A very great deal better.

Baseline and 6 weeks, 10 weeks, 14 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Physical activity enjoyment Scale (PACES)
Time Frame: 6 weeks

The examiners assess participant satisfaction with cervical deep muscle training.

This scale measures enjoyment during physical activity through 16 items, which are preceded by the phrase "When I am active…" This instrument measures enjoyment and bipolar enjoyment, through statements such as "I enjoy it", "I'm bored", "It's very exciting", and "I don't like it". The answers will be collected on a Likert scale from 1 (totally disagree) to 5 (totally agree).

6 weeks
The Borg Rating of Perceived Exertion (RPE) Scale.
Time Frame: 6 weeks

The examiners assess perceived exertion by the participant during exercise. The Rating of Perceived Exertion (RPE) scale is based on a range between 0 and 10, with 0 being the least amount of exertion and 10 being the maximum level of exertion.

The examiners assess perceived exertion by the participant during exercise.
