An interventional study of Core Stabilization Exercises and Whole-Body Vibration in Nonspecific Low Back Pain, sponsored by Istinye University. Not yet recruiting at 1 site in Turkey (Türkiye). Open to participants aged 18 Years to 30 Years. Per ClinicalTrials.gov, last updated 2026-11-06.
Sponsored by Istinye University · Not applicable, Interventional, and Supportive care
This study aims to investigate the immediate effects of three intervention approaches in young adults with nonspecific low back pain. Participants will be randomly assigned to one of three groups: core stabilization exercises, whole-body vibration combined with core stabilization exercises, or cervical stabilization combined with core stabilization exercises. Outcomes will be assessed before and immediately after the intervention. The study will evaluate trunk motor control, pain intensity, pressure pain threshold, trunk muscle endurance, and balance. The purpose is to compare the immediate effects of these approaches and determine whether adding whole-body vibration or cervical stabilization to core stabilization produces additional benefits.

Exclusion Criteria:
Participants in this group will perform the standard core stabilization exercise program, including the abdominal drawing-in maneuver, heel slide, single-leg march, single-leg extended heel tap, bridge, bridge pulse, dead bug, modified curl-up, and semi-plank. The total intervention duration is approximately 20 minutes.
Behavioral: Core Stabilization Exercises
Participants in this group will receive 5 minutes of whole-body vibration before the core stabilization exercise program. The vibration platform will be set at 30 Hz with an amplitude of 2 mm, and participants will stand with the knees slightly flexed during the vibration. Immediately afterward, participants will perform the same core stabilization exercise program used in the core stabilization group. After completing the core stabilization exercises, an additional 5 minutes of whole-body vibration will be applied using the same parameters. The total intervention duration is approximately 30 minutes.
Behavioral: Core Stabilization Exercises · Device: Whole-Body Vibration
Participants in this group will perform cervical stabilization exercises before the core stabilization exercise program. The cervical exercises will be performed in supine using a pressure biofeedback unit placed under the cervical spine. Participants will perform controlled craniocervical flexion, progressing the target pressure from 20 mmHg to 30 mmHg in 2 mmHg increments. The cervical stabilization exercises will be performed for approximately 5 minutes before the core stabilization program and repeated for an additional 5 minutes afterward. The total intervention duration is approximately 30 minutes.
Behavioral: Core Stabilization Exercises · Behavioral: Cervical Stabilization Exercises
Participants perform a core stabilization exercise program including the abdominal drawing-in maneuver, heel slide, single-leg march, single-leg extended heel tap, bridge, bridge pulse, dead bug, modified curl-up, and semi-plank. The program is designed to activate and control the deep trunk stabilizing muscles.
Whole-body vibration will be applied using a vibration platform at a frequency of 30 Hz and an amplitude of 2 mm. Participants will stand on the platform with the knees slightly flexed for 5 minutes before the core stabilization exercise program and for an additional 5 minutes after the program.
Participants will perform cervical stabilization exercises in the supine position using a pressure biofeedback unit placed under the cervical spine. Controlled craniocervical flexion will be performed with progressive target pressures from 20 mmHg to 30 mmHg in 2 mmHg increments. The exercises will be performed for approximately 5 minutes before the core stabilization program and repeated for an additional 5 minutes afterward.
Trunk motor control (supine), Pressure Biofeedback Unit
Deep abdominal muscle activation and lumbopelvic stability assessed with a pressure biofeedback unit in crook lying during the abdominal drawing-in maneuver, starting at 40 mmHg. The score is the absolute deviation from 40 mmHg (best of three trials); smaller values indicate better motor control.
Time frame: Baseline and immediately after the single intervention session
Trunk motor control (prone; transversus abdominis activation), Pressure Biofeedback Unit
Activation of the transversus abdominis assessed in prone lying with the pressure biofeedback unit placed under the abdomen and inflated to 70 mmHg. Participants draw the abdominal wall in without moving the spine or pelvis. The score is the pressure reduction from 70 mmHg held steadily (best of three trials); larger reductions indicate better activation.
Time frame: Baseline and immediately after the single intervention session
Pain intensity, Numeric Pain Rating Scale (NPRS)
Self-reported low back pain intensity rated from 0 (no pain) to 10 (worst imaginable pain). Lower scores indicate less pain.
Time frame: Baseline and immediately after the single intervention session
Pressure pain threshold, lumbar multifidus
Pressure pain threshold in kg/cm² measured with a pressure algometer 2 cm lateral to the L4 spinous process. The mean of three measurements is used. Higher values indicate lower pain sensitivity.
Time frame: Baseline and immediately after the single intervention session
Pressure pain threshold, erector spinae
Pressure pain threshold in kg/cm² measured with a pressure algometer 3 cm lateral to the L3 spinous process. The mean of three measurements is used. Higher values indicate lower pain sensitivity.
Time frame: Baseline and immediately after the single intervention session
Pressure pain threshold, thoracolumbar fascia
Pressure pain threshold in kg/cm² measured with a pressure algometer 5 cm lateral to the L3 level. The mean of three measurements is used. Higher values indicate lower pain sensitivity.
Time frame: Baseline and immediately after the single intervention session
Y-Balance Test composite score, right leg
Maximum reach in the anterior, posteromedial and posterolateral directions while standing on the right leg, normalized to right lower limb length and expressed as a composite score (%). Higher scores indicate better dynamic balance.
Time frame: Baseline and immediately after the single intervention session
Y-Balance Test composite score, left leg
Maximum reach in the anterior, posteromedial and posterolateral directions while standing on the left leg, normalized to left lower limb length and expressed as a composite score (%). Higher scores indicate better dynamic balance.
Time frame: Baseline and immediately after the single intervention session
Trunk flexor endurance test
Isometric holding time in seconds in the trunk flexor endurance test (McGill). Longer holding time indicates greater trunk flexor endurance.
Time frame: Baseline and immediately after the single intervention session
Prone plank test
Isometric holding time in seconds in the prone plank position. Longer holding time indicates greater trunk muscle endurance.
Time frame: Baseline and immediately after the single intervention session
Right side bridge test
Isometric holding time in seconds in the right side bridge test (McGill). Longer holding time indicates greater lateral trunk endurance.
Time frame: Baseline and immediately after the single intervention session
Left side bridge test
Isometric holding time in seconds in the left side bridge test (McGill). Longer holding time indicates greater lateral trunk endurance.
Time frame: Baseline and immediately after the single intervention session

Start is estimated for Oct 2026; primary completion for Oct 2027, 12 months later.
Of 1,231 non-industry interventional studies with no phase under Low Back Pain, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 26. This study's planned 12 months is close to that.
Counting every sponsor, half of 1,286 studies reached it within 11 months; a quarter within 5 and three quarters within 27.
