简要总结

The goal of this observational study is to evaluate the immediate effects of cranio-cervical flexion exercises and correct posture training on upper extremity and trunk kinematics during functional activities in young adults with neck pain.

The main questions it aims to answer are:

Does the immediate cranio-cervical flexion and posture training improve postural control and induce immediate changes in individuals with neck pain?
Does this training intervention enhance functional movement and daily activity performance from a kinematic analysis perspective?

Participants will:

Undergo a baseline assessment, where sociodemographic and physical data will be recorded using the Numeric Pain Rating Scale (NPRS) and the Neck Disability Index (NDI).

Receive cranio-cervical flexion and correct posture training as an intervention, after which the evaluation will proceed immediately.

Perform functional activities (typing, talking on the phone, eating, lifting a load), with each activity being repeated three times, and these will be evaluated using 3D kinematic analysis with the Movella XSens (MVN Awinda) system.

详细描述

The motivation for this study stems from the observation that previous research has primarily focused on the long-term effects of craniocervical flexion exercises, while the immediate effects of such exercises have not been explored. Craniocervical flexion exercises and correct posture training have been shown to be effective in reducing neck pain and improving functionality. Therefore, this study aims to examine the immediate impact of craniocervical flexion exercises and correct posture training on upper extremity and trunk kinematics during functional activities.This study aimed to examine the immediate effects of cranio-cervical flexion exercises and correct posture training on upper extremity and trunk kinematics during functional activities in individuals with neck pain. The study was a cross-sectional design conducted at XXX University, Faculty of Physical Therapy and Rehabilitation, and was approved by the university's ethics committee (FTREK 24/117).

A total of 28 young adults (aged 18-35) with chronic neck pain participated in the study. Participants were selected based on specific inclusion criteria, including a minimum Neck Disability Index (NDI) score of 20%. Individuals with congenital or acquired spinal deformities, herniated discs, neurological or vestibular disorders, and pregnant individuals were excluded. Participants were randomly divided into two groups: one group received immediate cranio-cervical flexion and correct posture training, while the other group followed their routine daily activities. At the end of the study, the second group also received the same training program.

The study consisted of three phases: baseline assessment, immediate training intervention, and post-training assessment. During the baseline phase, sociodemographic, physical, and pain-related data were collected. In the immediate training intervention phase, participants in the intervention group were instructed in cranio-cervical flexion exercises and correct posture training. In the post-training phase, functional tasks such as typing, phone conversation, heavy load lifting, and eating were performed. Kinematic changes during these tasks were assessed using a 3D inertial measurement system (Movella XSens), which is well-regarded for its reliability in biomechanical research.

Sample size calculation using G*Power software indicated that a total of 28 participants (14 per group) was sufficient to achieve 80% statistical power with an alpha level of 0.05. Data were analyzed using SPSS Version 26.0 to assess the immediate effects of the cranio-cervical flexion and posture training on kinematic parameters during the functional tasks.

研究组 & 干预措施

Untrained group

No Intervention

Trained Group

Other

In the trained group, participants received immediate instruction on craniocervical flexion exercises and correct posture. They were guided through the exercises and provided feedback to ensure proper technique and activation of the deep cervical flexor muscles.The craniocervical flexion and correct posture training were given immediately during the assessment, with no follow-up sessions or long-term interventions. The focus was solely on providing the training at that moment, without any prolonged or repeated exercises.

结局指标

主要结局

Kinematic Parameters of Functional Activities (Upper Extremity and Trunk) - T1C7 Flexion/Extension MAX ROM/MİN ROM/ F-ROM

时间窗: Through study intervention, an average of 15 minutes

Immediate changes in the kinematic parameters of upper extremity, trunk, and head movements during functional tasks (typing, phone conversation, heavy load lifting, and eating) after the instantaneous cranio-cervical flexion and correct posture training. Joint range of motion will be assessed using the Movella XSens inertial measurement system (MVN Awinda), and it will be evaluated in degrees using the MVN Analyze software.
