Low Back Pain

Brief summary

Low back pain is one of the most common complaints in the world and can be considered a universal health problem for humanity. Low back pain is a multifactorial disease with multiple etiologies. Risk factors are difficult to identify. It is reported in the literature that 70-80% of the world's population has low back pain at some point in their lives, and 95% of this pain is mechanical. Mechanical low back pain (MBA) can be described as a clinical picture that develops as a result of overuse, strain, traumatization or deformation of the structures that make up the spine. In order to define low back pain mechanically, all organic causes such as inflammatory, infectious, tumoral, metabolic causes, fractures and pain reflected from internal organs must be excluded. The most common diseases that cause low back pain are; They are caused by mechanical factors and degenerative diseases. Mechanical and static stresses can lead to joint blockage, restricting the range of motion of the joint along with pain. Non-Specific many factors affect low back pain. Kim and Shin reported that asymmetry of hip extension range of motion of both hip joints was associated with nonspecific low back pain rather than simple hip extension range of motion, and they found that limiting hip extension was compensatory.

Design outcomes

Primary

MeasureTime frameDescription
Flexibility assessment0-4 weekDuring the Passive Knee Extension Test, participants will be positioned supine with the hip of the tested limb flexed to 90° while the contralateral limb will be stabilized. The examiner gradually extended the knee until resistance or discomfort will reported. The knee extension angle will be measured using a digital goniometer and recorded in degrees.

Secondary

MeasureTime frameDescription
Functionality index0-4 weekFunctional Rating Index (FDI) was obtained by combining similar structures of the neck disability index and the Osweestry low back pain disability index, and its validity and reliability have been proven. The validity and reliability of the Turkish version of this survey was conducted by Bayar et al. in 2004. FDI consists of 10 parts that measure the function of the spinal musculoskeletal (waist, neck pain) system and pain. Eight address activities of daily living that may be affected by the spinal condition. Two of them address 2 different characteristics of pain. Using a 5-choice scale for each item, the amount of current pain or perceived ability to function is ranked by selecting 5 response points. 0=no pain or full function, 1=mild pain or mild limitation, 2=moderate pain or moderate limitation, 3=severe pain or severe limitation, 4=worst pain or inability to function. Scoring varies between 0-40, and as the score increases, functional status worsens
Functional disability0-4 weekFunctional disability will be assessed using the Oswestry Disability Index (ODI). The ODI consists of 10 items evaluating pain intensity and disability during daily activities. Each item will be scored from 0 to 5, with higher scores indicating greater disability. The Turkish version of the ODI has demonstrated acceptable validity and reliability (Yakut et al., 2004). ODI scores will be categorized as minimal (0-20), moderate (21-40), severe (41-60), crippled (61-80), and bed-bound (81-100) disability. A 30% improvement from baseline will be considered the threshold for clinically meaningful improvement in individuals with low back pain.
Pain status0-4 weekPain status Patients pain status were evaluated with VAS between 0 and 10 for low back pain during movement. (No pain at 0 points, severe pain at 10 points)
Jump performance0-4 weekVertical jump performance will be assessed using the squat jump (SJ) test. Participants will start from a semi-squat position without preparatory countermovement and will be instructed to jump as high as possible. Jump height will be measured using a Vertec system, which has demonstrated acceptable validity and reliability for vertical jump assessment. Three trials will be performed under standardized conditions, and the highest value will be recorded. Jump height will be calculated as the difference between standing reach height and maximal jump reach height and will be recorded in centimeters.
