About this study
This study will be conducted to investigate the correlation between the flexibility of hip muscles; hip flexors (iliopsoas, rectus femoris), hip extensors (hamstring), hip internal rotators, hip external rotators, hip adductors and hip abductors with pain intensity and disability level among patients with chronic nonspecific low back pain
Read the detailed description
Low back pain is considered the primary cause of disability worldwide. Low back pain is pain located at the area from the last ribs to the gluteal region with or without radiation to the lower limbs. Low back pain is associated with substantial economic burden, resulting from healthcare expenses, reduced productivity, insurance costs and sick leaves.
It was reported that limitation of hip range of motion of low-back pain patients was significantly different from that of healthy person. Due to the anatomic proximity and muscle connections, a number of studies have investigated the relationship between hip mobility and episodes of low back pain. From biomechanical point of view limited hip range of motion is compensated by hypermobility of the lumbar region thus generating overload with repetitive compensatory movements in the back.
Patients with non-specific low back pain demonstrate alteration in hip muscles flexibility. This relationship is important because the hip muscles act as an important link between the lower limbs and the trunk exerting forces from the lower limbs to the spine as well as from the spine. Any flexibility limitations of hip muscles not only decreases the range of motion but can also cause excessive mechanical stresses to lumbar spine during particular movement, thus affecting gait and other functional movements.
Up to the author's knowledge, there is few studies that investigates the correlation between the flexibility of all hip muscles and pain intensity and disability level in nonspecific low back pain patients. Therefore, this study aims to assess the correlation between the flexibility of hip muscles; hip flexors (iliopsoas, rectus femoris), hip extensors (hamstring), hip internal rotators, hip external rotators, hip adductors and hip abductors with pain intensity and disability among patients with chronic nonspecific low back pain.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| 50 subjects aged between 20 and 45 years of both sexes with diagnosis of nonspecific low back pain | Not described |
What is being measured
The primary outcome is the main question the study is designed to answer.
Flexibility of Hip Muscles
Flexibility of the muscles of hip will be conducted on both the right and lift side and will be measure by universal Goniometer
Measured: up to 1 day
Pain Intensity
Visual analog scale is globally used as a measure of pain intensity. Visual analogue scale is the most frequent outcome tools in musculoskeletal pain assessment. An overall score between 0 and 10 points is given, with 'no pain' defined as 0 points and 'the most severe pain possible' defined as 10 points.
Measured: up to 1 day
Disability
Oswestry disability index is an internally consistent, unidimensional scale with overall excellent construct validity and ability to discriminate the severity of functional disability. The analysis suggests that the Oswestry disability index may better distinguish between the relative degrees of function at above-average disability levels. The Oswestry disability index is used to assess the extent of disability caused by low back pain, The Oswestry disability index consists of 10 questions on pain intensity, personal care, lifting, walking, sitting, standing, sleeping, sexual activity, social life, and travel. Performance in each item is described in 6 stages, from 0 to 5 points, A higher score on the Oswestry disability index indicates more severe disability
Measured: up to 1 day

This study will be conducted to investigate the correlation between the flexibility of hip muscles; hip flexors (iliopsoas, rectus femoris), hip extensors (hamstring), hip internal rotators, hip external rotators, hip adductors and hip abductors with pain intensity and disability level among patients with chronic nonspecific low back pain
