Brief Summary

the aim of the study is to investigate the impact of gender difference on knee proprioception among non specific low back pain young adults.

Detailed Description

Low back pain (LBP) is one of the most common musculoskeletal disorders and the leading causes of disability and work absence globally. LBP notonly causes individual suffering, but also a heavy burden to the society. Despite this, up to 85% patients with LBP cannot be clearly diagnosed and are classified as non-specific LBP (NSLBP). Proprioception plays an important role in the planning of precise and coordinated movements, in maintaining balance and controlling body posture. It also exerts its influence on motor learning and re-education. Proprioception deficit has been identified in people with LBP and it has been suggested that these deficits might be associated with causes and mechanisms of LBP. Although the local investigation of proprioception is important, the proprioceptive deficits due to LBP may not be restricted only to the lumbar region. Anatomical and biomechanical associations between the knee and lower back segments imply that the knee might be adversely affected in patients with LBP.

there is a gap in the literature concerning sex differences in the knee joint proprioception. Although biomechanical and hormonal differences between males and females are suspected to be responsible for increasing this incidence.

Study Design

• Observational Model Type: CASE_CONTROL
• Study Time Perspective: CROSS_SECTIONAL

Study Groups

Males

Forty-one males will be evaluated using digital inclinometer in an open kinetic chain position. The JPS testing is conducted in the sitting position without feet floor contact, at a quiet place with closed eyes . Investigator will perform all the knee joint position sense assessments in the dominant extremity. The digital inclinometer is stabilized to the middle third of the subjects' leg (15 cm distal from the apex of the fibular head) with a strap. The starting position of the test is 90° flexion. The proprioception evaluation angle is defined at 30°. Participants are asked to extend their tested knee to the target angle of 30° from the initial position (90° knee flexion) then to return to their initial position after 5 seconds in this position ,The participant indicated by saying "YES" when they thought they reach the target, and the reposition accuracy will be measured as the joint position error (JPE) in degrees, as displayed on the digital inclinometer screen
