Completed

• Conditions: Subjects With Deep Cervical Muscle Strength Deficit

• Registration Number: NCT05331482
• Lead Sponsor: Universitat Internacional de Catalunya

Brief Summary

The purpose of this study is to evaluate the clinical results in lower cervical range of motion, size deep muscles, endurance, craniovertebral angle and cervical propioception 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.

Detailed Description

Neck pain is one of the major public health problems, which has a great impact on people's lives, with high prevalence and recurrence rate. Cervical vertebral column is heavily dependent on the muscles for its physical support and activities. There are increasing evidences to support that cervical muscles may impair in patients with neck disorders. Training protocols can help to improve pain, cervical function, posture and cross-sectional area. However, there are no training protocols in subjects with strength deficit of deep cervical muscles, 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

Name	Time	Method
Measurement of Cervical Multifidus and Longus Colli Muscle size.	Baseline and 6 weeks, 10 weeks, 14 weeks	The examiners assess these deep muscles with ultrasound after 6 weeks, 10 weeks and 14 weeks.
Physical activity enjoyment Scale (PACES)	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).
Deep neck flexor endurance Test.	Baseline and 6 weeks, 10 weeks, 14 weeks	The Chin Tuck Neck Flexion Test is an assessment technique intended to determine the endurance of the deep cervical flexors.
Neck extensor muscle endurance Test	Baseline and 6 weeks, 10 weeks, 14 weeks	Mean change from baseline in neck extensor muscle endurance Test after 6 weeks, 10 weeks and 14 weeks. The examiners assess the endurance of deep cervical extensor muscle.
