This randomized controlled study aims to investigate the effects of a sensorimotor training protocol using a mobilized balance platform device on proprioceptive system function, movement control, balance, physical performance, pain severity, and quality of life in patients with chronic low back pain. A total of 44 patients with chronic low back pain will be recruited from the outpatient clinic of Gaziler Physical Medicine and Rehabilitation Training and Research Hospital.
Participants will be randomly assigned to either a sensorimotor training group or a control group. The intervention group will receive sensorimotor training using the Huber 360 balance system, while the control group will perform a home exercise program including stretching, spinal mobility, lumbopelvic control, and balance exercises.
Pain severity, proprioception, functional status, balance, physical performance, and quality of life will be assessed before and after treatment by an assessor blinded to group allocation.
Individuals aged between 18 and 55 years
Presence of chronic low back pain lasting at least 3 months
Pain intensity score of 3 or higher on the Visual Analog Scale (VAS)
Individuals with sufficient cognitive ability to understand and follow study procedures
Participation in a similar training program within the last 12 months
History of lower extremity or spinal surgery
Presence of non-mechanical low back pain, inflammatory disease, or tumor
Uncontrolled hypertension or cardiac disease
Parallel
Huber 360 Sensorimotor Training
DeviceParticipants will receive sensorimotor training using the Huber 360 balance system. The protocol will include progressive rotational and oscillatory exercises designed to improve proprioception, balance, neuromuscular control, and movement control in patients with chronic low back pain. Sessions will be performed for 30 minutes, twice weekly for 5 weeks.
Home Exercise Program
BehavioralParticipants will perform a home exercise program including warm-up and stretching exercises, spinal mobility exercises, lumbopelvic control exercises, and balance exercises. The program will be performed for 30 minutes per session, twice weekly for 5 weeks.
Lumbar Proprioception Assessment
Lumbar proprioception will be assessed using lumbar repositioning tests at 60 degrees flexion and 15 degrees extension. Participants will be asked to reproduce target lumbar positions, and the angular repositioning error will be recorded. Lower repositioning error values indicate better lumbar proprioceptive accuracy.
Pain Severity Assessed by Visual Analog Scale
Pain intensity will be assessed using a 10-cm Visual Analog Scale (VAS). Scores range from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater pain severity.
Functional Status Assessed by Oswestry Disability Index
Functional disability related to low back pain will be assessed using the Oswestry Disability Index (ODI). Higher scores indicate greater disability.
Balance and Limits of Stability Assessed by Huber 360
Static balance, dynamic balance, and limits of stability will be assessed using the Huber 360 balance system. Better balance performance and improved stability limits indicate better postural control.
Lumbar Flexion Range of Motion
Physical performance will be assessed using a Physical Performance Test Battery including lumbar flexion range of motion, 50-step walking test, 5-minute walking test, five-repetition sit-to-stand test, ten-repetition trunk flexion test, and forward reaching with weight.
