The comparison of trunk balance exercises and whole body vibration on the postural control of the patients with chronic non-specific low back pain. 2016-09-22 anticipated 50 Complete https://irct.ir/trial/23426 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: In this study, the randomization with block size of four was used. One group was indicated with the letter A and the other with the letter B. Then different blocks of AABB was written. They were assigned the number of 1-6. For example(AABB=1,ABAB=2,BABA=3,BBAA=4,BAAB=5, ABBA=6 A number was randomly selected between 1-6 and the selected number indicated the pattern of assigning individuals to groups, Blinding description: The assessment of ultrasound measurements(muscle thickness and cross sectional area) were conducted by an assessor who was blinded to interventions. N/A low back pain. Intervention 1: In balance training group intervention consists of 18 sessions,3 times and 6 weeks. Modalities ( TENS : low frequency=1-4 Hz, duration =100-400 micro sec, amplitude as tolerated, hot pack, US = 1 MHz ,intensity 1.5 w/cm2) are used. After that, patients execute trunk balance exercises in 5 levels. The levels of exercises are simple to difficult, and if his/her pain increases, the patient remains at the same level of exercises. The total duration of treatment is 6 weeks ,3 times per week . Intervention 2: For the whole body vibration group intervention consists of 18 sessions, 3 times and 6 weeks. Modalities ( TENS : low frequency=1-4 Hz, duration =100-400 micro sec, amplitude as tolerated, hot pack, US = 1 MHz, intensity 1.5 w/cm2) are used. After that , whole body vibration device (sinusoidal mode, frequency= 20 Hz, amplitude= 4mm, a= 5.8 g) is used for them. The patients stands with 20 flexion of knee joints on plate form. 5 boot uses in each session with 1 minute rest between them. Duration of each boot in first 2 week is 30 seconds, in second 2 week 45 seconds and in the last 2 week is 1 minute. The total duration of intervention is the same as other group. https://doi.org/10.1016/j.medengphy.2018.07.006 Patients with low back pain (LBP) have reduced core muscle geometry and impaired postural balance. Impaired trunk control was shown to be associated with poor balance and limited functional mobility in these patients. However, the relationship between muscle geometry and postural balance is unclear. This study aimed to determine the correlation of core muscle geometry with pain intensity, functional disability and postural balance in patients with chronic nonspecific mechanical LBP. Thirty patients aged 20–50 years were enrolled. Ultrasound imaging was used to assess their muscle geometry. The participants completed a numerical rating scale (NRS) for pain severity, and the Persian version of the Roland–Morris Disability Questionnaire (PRMDQ). To estimate static balance, they were asked to perform the single leg stance test. Dynamic balance was assessed with the Y-balance test. Significant correlations were found between NRS scores and bilateral multifidus cross-sectional area during rest ( r ≥−0.31, P ≤0.04) and con- traction ( r ≥−0.37, P ≤0.02). NRS scores correlated significantly with bilateral multifidus thickness during rest ( r ≥−0.31, P ≤0.04) and contraction ( r ≥−0.28, P ≤0.04). Significant correlations were also observed for PRMDQ scores with thickness ( r ≥−0.35, P = 0.04) and cross-sectional area of the multifidus muscles ( r ≥−0.33, P = 0.04) bilaterally during contraction. A significant correlation was found between Y-balance scores and right abdominal muscle thickness during rest and contraction ( r ≥0.34, P ≤0.04). Core muscle geometry correlated with pain, functional disability indices and dynamic balance in these patients.
