Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Chronic low back pain is a common musculoskeletal condition persisting for more than three months and is associated with pain, functional limitations, impaired balance, altered proprioception, reduced trunk muscle performance, and decreased quality of life. Previous studies have demonstrated that individuals with chronic low back pain exhibit altered sensory input from spinal structures and impaired neuromuscular control, which may contribute to persistent pain and movement dysfunction. Although exercise-based physiotherapy approaches, particularly core stabilization exercises, are widely recommended and effective in the management of chronic low back pain, sensory deficits related to balance, proprioception, and body awareness are often insufficiently addressed in conventional rehabilitation programs.

Vertebral axial loading walking training is a functional rehabilitation approach involving slow, controlled walking under gentle vertical loading applied along the spinal axis. This intervention is thought to enhance afferent sensory input from spinal mechanoreceptors, potentially improving balance control, proprioception, and motor coordination. This randomized controlled study aims to investigate the effects of adding vertebral axial loading walking training to a standard core stabilization exercise program on pain intensity, balance, proprioception, trunk muscle strength and endurance, and body awareness in individuals with chronic low back pain.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Chronic low back pain is one of the leading causes of disability worldwide and is characterized not only by persistent pain but also by impairments in postural control, proprioception, trunk muscle function, and body awareness. Neurophysiological studies have demonstrated that individuals with chronic low back pain exhibit altered afferent input from lumbar spinal structures and changes in central nervous system processing, resulting in impaired sensorimotor control and delayed trunk muscle activation. These alterations may negatively affect balance, movement coordination, and functional performance, thereby contributing to the chronicity of symptoms. Core stabilization exercises are commonly prescribed to improve trunk muscle strength, endurance, and neuromuscular control and have demonstrated beneficial effects in individuals with chronic low back pain. However, evidence suggests that traditional exercise programs may not sufficiently stimulate sensory receptors involved in proprioceptive input and postural regulation. Impaired proprioception and reduced body awareness have been identified as key factors associated with ongoing pain and functional limitations in this population. Vertebral axial loading walking training is a novel and functional intervention that applies gentle vertical loading along the spinal axis during slow and controlled walking. Axial loading is thought to stimulate spinal mechanoreceptors and enhance sensory feedback, thereby facilitating improved proprioceptive awareness, postural stability, and motor coordination during functional activities. This approach is practical, cost-effective, and easily integrated into rehabilitation settings. In this randomized controlled study, participants with chronic low back pain will be allocated to either a core stabilization exercise program alone or a combined intervention consisting of core stabilization exercises and vertebral axial loading walking training. Outcome measures will include pain intensity, balance performance, lumbar proprioception, trunk muscle strength and endurance, and body awareness. Assessments will be conducted at baseline and after the intervention period. The results of this study are expected to provide evidence for a more comprehensive rehabilitation strategy by integrating sensory-based and functional axial loading approaches into physiotherapy programs for individuals with chronic low back pain.

Study Groups

Core Stabilization Exercises plus Vertebral Axial Loading Walking Training (CSE+ALWT Group)

Participants in this group receive a standardized core stabilization exercise program combined with vertebral axial loading proprioceptive walking training. The intervention is supervised by a physiotherapist and applied three sessions per week for six weeks.

Group Type EXPERIMENTAL

Core Stabilization Exercises Plus Vertebral Axial Loading Walking Training

Intervention Type BEHAVIORAL

Participants receive the same core stabilization exercise program combined with vertebral axial loading proprioceptive walking training. Axial loading is applied through the vertex of the head using external weights ranging from 50 to 250 grams, adjusted according to individual tolerance. Walking is performed at a constant slow pace using a metronome set at 72 beats per minute. The initial walking distance is 40 meters and is progressively increased by 20 meters per week, reaching up to 140 meters. The intervention is supervised by a physiotherapist and applied three sessions per week for six weeks.

Core Stabilization Exercises Only (CSE Group)

Participants in this group receive the standardized core stabilization exercise program alone, supervised by a physiotherapist, three sessions per week for six weeks.

Group Type ACTIVE_COMPARATOR

Exercise - Core Stabilization Exercise Program

Intervention Type BEHAVIORAL

Participants receive a physiotherapist-supervised core stabilization exercise program applied three sessions per week for six weeks. Before training, participants are educated about core muscle function and taught the abdominal bracing maneuver. Exercises are performed with neutral spinal alignment and controlled diaphragmatic breathing. Each session includes warm-up and cool-down exercises. The program consists of deep abdominal muscle activation, lower extremity movements with maintained trunk stability, bridging exercises, modified curl-up, and quadruped stabilization exercises. Exercises are demonstrated by the physiotherapist, performed with progressive repetitions, and corrected using verbal and manual feedback. The training is supervised by a physiotherapist and applied three sessions per week for six weeks.
