Aims and background: Low back pain is a common ailment that affects about 80% of the population at some point in their life time. Using a brace is a method to control pain that physiotherapists recommend it. However, the scientific evidence about the effects of different braces in low back pain patients is limited. Therefore, the aim of this study was to evaluate the effects of two thoracol...
There are many possible means of determining job exposure ranging from job Classifications through to self reports of physical exposure to measures of muscle activations and estimated spinal loads.We suggest a fruitful approach is to develop a framework which allows one to combine instruments to take advantage of the best features of each instrument. We suggest that using a common metric allows...
BACKGROUND AND PURPOSE Pain is currently evaluated with "subjective" methods (eg, patient self-report). This study aimed to test whether fatigue indexes are able to accurately discriminate between subjects with and subjects without low back pain. SUBJECTS Sixty subjects separated into 2 groups--a group with low back pain (n=30) and a group without low back pain (n=30)--participated in this st...
Electromyographic (EMG) contralateral imbalances of back muscles are often interpreted as an aberrant back muscle pattern related to back pain. This study assessed different measurement properties (influence of the control of asymmetric efforts and of the force level, reliability, and sensitivity to low back status) of EMG imbalance parameters. Healthy controls (n = 34) and chronic low back pai...
The first test for evaluating the isometric endurance of trunk extensor muscles was described by Hansen in 1964. In 1984, following a study by Biering-Sorensen, this test became known as the "Sorensen test" and gained considerable popularity as a tool reported to predict low back pain within the next year in males. The test consists in measuring the amount of time a person can hold the unsuppor...
Abstract Objective: Comparison of global and local abdominal muscles thickness in chronic non-specific low back pain patients with healthy controls in position of hook-lying over variant stability surface utilizing diagnostic ultrasonography Methods and Materials: 20 chronic non-specific low back pain male patients compared with a convenient sample of age and gender matched healthy con...
Background: The aim of this study was to evaluate the effect of online yoga exercises on pain, functional disability and functional tests of the torso and lumbar in middle-aged women with nonspecific chronic low back pain in the Covid 19 pandemic. Methods: The research was quasi-experimental and applied study. Thirty women with nonspecific chronic low back pain in the age range of 35 to 55 ye...
Background & Aims: Prolonged standing in static posture during occupational tasks has been associated with low back pain (LBP). Increased bilateral gluteus medius (GM) muscles co-activation is considered to be the most predisposing factor for LBP development during prolonged standing in asymptomatic individual. Change and modify flooring in occupational environment is common ergonomic interve...
Background and Objectives: Low back pain is a musculoskeletal disorder with an annual prevalence of 18.6%. The aim of the present study was to evaluate the effect of rehabilitation with medicine ball on directed and general co-contraction of knee joint muscles in low back patients during walking, Materials and Methods: The present study was a clinical trial. The statistical population of the p...
BACKGROUND Low back disorders are a prevalent problem in society today and may lead to chronic debilitating low back pain. Developing our understanding of temporal muscle and kinematic patterns during manual material handling tasks may provide insight for preventing the cascading series of events leading to chronic low back pain. METHODS Sixty-two low back pain patients and 61 asymptomatic pa...
