Hamstring Stretching Effective on Nonspecific Low Back Pain (Hams)

Does Hamstring Stretching Effective on Nonspecific Low Back Pain?"

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pain status	Pain 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)	0-8 week
Flexibility assessment	During Single Leg Raise, subjects were asked to indicate (by pushing a button) the beginning of pain or an unpleasant tension sensation in the dorsal part of the thigh off the knee. This first sensation of pain was recorded as a function of the pelvic-femoral angle. Subjects were also instructed to push the button and to say "stop" when they could no longer tolerate more movement or stretch; at that point, the leg raise was stopped. The stretch tolerance was defined by the extensibility of the hamstrings. Note that the subjects stopped the leg raise.	0-8 week

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Functionality index	Functional 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	0-8 week
FUNCTIONAL STATUS	It consists of 10 questions, each scored between 0 and 5, assessing pain, personal care, lifting loads, walking, sitting, standing, sleeping, social life, traveling and the degree of change in pain. The maximum score is 50 and the total score is multiplied by two and the result is given as a percentage. Evaluation; It is done with the formula score/total score (50) x 100 = %. This form is a form with proven validity and reliability in Turkish for patients with chronic low back pain, used to evaluate treatment results and compare different treatment	0-8 week
