Effects of Pelvic-Tilt Imbalance on Disability, Muscle Performance, and Range of Motion in Office Workers with Non-Specific Low-Back Pain

Abstract

Imbalance in the pelvic tilt is considered to be a major variable in low back pain. The purpose of this study was to investigate the effects of pelvic-tilt imbalance on trunk- and hip-muscle performance, range of motion, low-back pain, and the degree of disability in office workers. This was a cross-sectional study conducted in a physical therapy clinic on forty-one office workers diagnosed with non-specific low-back pain. Among the office workers with non-specific low-back pain, 25 were assigned to the pelvic-tilt-imbalance group and 16 to the normal group without pelvic-tilt imbalance. In order to determine the differences according to the imbalance in pelvic tilt, the pain intensity and disability indices were compared between the groups. In addition, the muscle performance and range of motion of the trunk and hip joints and foot pressure were measured and compared. There were differences between the groups in the disability indices and the ratio of internal and external rotation of the hip joint. However, there were no differences in the other variables. Pelvic-tilt imbalance in office workers with non-specific chronic low-back pain may exacerbate the degree of disability and be related to hip-joint rotational range of motion.

Correlation between Bilateral Muscle Loading Asymmetry and Neck Pain - A Prospective Cross-Sectional Study

“…The study also found a correlation of r=0.632 between the visual analogue scale and the neck disability score, showing that neck pain can induce moderate functional impairment in the neck [13]. Furthermore, weak muscles are thought to make it difficult to maintain balance and appropriate posture while performing daily duties, which raises the risk of pain and body asymmetry [6].…”

“…It is therefore feasible to speculate that the posterior spinal muscles, through the thoracolumbar fascia, connect the lower trunk to the neck. Certain studies have shown a strong correlation between the cervical and pelvic spine's posture and the alignment of the complete spine [6,20,23].…”

“…Postural stability, function, and overall movement all depend on the posterior chain [4]. Asymmetry of spinal segments and lower back discomfort; asymmetry of hip muscles and unequal weight distribution; asymmetry of the lower limbs and unpredictable gait; and neck pain and scapular asymmetry are among the conditions for which numerous studies have looked at the effects and consequences of muscle imbalances [5,6].…”

Functional analysis of postural spinal and pelvic parameters using static and dynamic spinometry

“…In fact, non-specific back pain implies no known pathoanatomical cause and is the most common reason for chronic low back pain - approximately 90% of cases [ [ 6 ]]. Unconscious movement patterns (such as lifting household items [ [ 7 ]]) typically cause this pain, which can result in hypertonic, painful muscles and reduced joint mobility [ [ 8 , 9 ]]. Conventional imaging methods such as X-ray or higher resolution imaging using Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) [ [ 10 ]] primarily cannot detect these conditions.…”

Enhanced Pain Relief and Muscle Growth in Individuals with Low Back Instability: The Impact of Blood Flow Restriction Exercise during Sit to Stand Movements

“…Lower back pain (LBP) is common and the leading cause of musculoskeletal disorder that frequently occurs because of muscle and ligament damage caused by excessive lower back movement and incorrect posture [ 1 ]. Back pain causes muscle weakness in the lower back, limits the range of motion of the joints [ 2 ], and leads to back instability due to asymmetrical spinal movements [ 3 ]. In LBP, the main aim of physical therapy and rehabilitation is to reduce pain and enhance motor function in the back area through various intervention methods, such as muscle strengthening, aerobic exercise, coordination exercise, corrective exercise, and trunk-centered exercise [ 4 ].…”
