About

This study aimed to examine the effectiveness of a polyvagal theory-based exercise approach on joint position sense, pain, range of motion, functionality, depression, and quality of life in individuals with chronic neck pain.

H0 = The polyvagal theory-based exercise approach has no significant effect on joint position sense, neck pain, range of motion, functionality, depression, or quality of life.

H1 = The polyvagal theory-based exercise approach has a significant effect on joint position sense, neck pain, range of motion, functionality, depression, and quality of life.

Full description

Neck pain is one of the most common musculoskeletal problems that negatively impacts individuals' health and quality of life. When chronic painful conditions occur in musculoskeletal disorders, mood disorders such as depression and anxiety can also occur. A long-term history of neck pain is associated with stress, poor quality of life, and decreased functionality.

Polyvagal theory advocates working with the body, becoming aware of it, and connecting with the senses. Exercises based on polyvagal theory can be specifically designed and customized to stimulate the vagus nerve, promote relaxation, and enhance social interaction by following the principles of polyvagal theory.

While polyvagal theory is often used in psychology, it has only been used in rehabilitation in one study, with the potential to improve quality of life by inhibiting the sympathetic nervous system and activating the parasympathetic nervous system, thereby reducing pain perception and stress.

This study, in which participants were divided into three groups: control, intervention 1, and intervention 2, aimed to examine the effectiveness of a polyvagal theory-based exercise approach on joint position sense, pain, range of motion, functionality, depression, and quality of life in individuals with chronic neck pain.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

---

75 participants in 3 patient groups

Control

Active Comparator group

Description:

Participants in this group will undergo traditional, painless cervical exercises twice a week for 8 weeks. The intervention will not lead to progression, and the same intervention content will be used for 16 sessions. The exercises will be performed by a physical therapist.

Treatment:

Other: Control

Intervention 1

Experimental group

Description:

Participants in this study will undergo exercises based on polyvagal theory twice a week for 8 weeks. The exercise content will be one set. The intervention will not be progressive, and the same intervention content will be used for 16 sessions. The intervention will be administered by a physical therapist.

Treatment:

Other: Intervention 1

Intervention 2

Experimental group

Description:

Participants in this study will receive exercises based on polyvagal theory in addition to traditional, painless cervical exercises twice a week for 8 weeks. Each exercise will be performed for 10 repetitions and 3 sets. Polyvagal theory-based exercises will be performed for 1 set. The intervention will be non-progressive and will use the same intervention content for 16 sessions. The intervention will be administered by a physical therapist.

Treatment:

Other: Intervention 2
