PURPOSE: this study aimed to investigate the effect of opposite knee position on hamstring flexibility BACKGROUND Hamstrings tightness is one of the most common findings in patients with LBP. It is thought that, due to the attachments of hamstrings to the ischial tuberosity, hamstrings tightness generates posterior pelvic tilt and decreases lumbar lordosis, which can result in LBP.
HYPOTHESES There will be significant difference in the hamstring flexibility with changing position of opposite knee (flexed or extended) in patients with mechanical low back pain.
RESEARCH QUESTION: Will changing position of opposite knee (flexed or extended) affect the hamstring flexibility in patients with mechanical low back pain?
- The subject will be instructed to maintain 90° hip flexion in the supine position.
- Then asked to actively extend the knee joint.
- The degree of achieving active knee extension will be measured using a universal goniometer.
- The average of three active knee extension measurements will be recorded used as the hamstring muscle length for the data analysis (Dong-Kyu Lee, et al., 2018).
- This test will be done for the same limb with opposite leg extended and with opposite flexed.

The purposes of this double-blinded, randomized controlled trial are (1) to determine if the addition of trigger point dry needling (TDN) to a standard stretching program results in greate...
Mobility training in the form of stretching and flexibility training of our skeletal muscle is a common exercise. However, the evidence are scare and there are only a few studies comparing...
The flexibility of the hamstrings is a very important component both for general health and when exercising. The lack of hamstring flexibility has been related to the increase in the likel...
Cognitive and behavioral flexibility are important predictors of adaptive behavior in school-age autistic youth. While prior research has utilized broad measures of flexibility, the current study uses...
New wave therapies such as Acceptance and Commitment Therapy aim to cultivate people's psychological flexibility in order for them to live a satisfying life. Psychological flexibility has also a role ...
A growing body of research has examined regulatory flexibility as the ability to dynamically modulate emotional expression and experience (Bonanno & Burton, 2013). The late positive potential (LPP), a...
Pattern separation aids cognitive flexibility by reducing interference between closely related memories. Dentate gyrus (DG) neurogenesis may facilitate pattern separation by blocking memory retrieval ...

Small computers that lack the speed, memory capacity, and instructional capability of the full-size computer but usually retain its programmable flexibility. They are larger, faster, and more flexible, powerful, and expensive than microcomputers.
Materials incorporated mechanically in plastics (usually PVC) to increase flexibility, workability or distensibility; due to the non-chemical inclusion, plasticizers leach out from the plastic and are found in body fluids and the general environment.
A group of tendons that attach the HAMSTRING MUSCLES proximally to the PELVIS and to the TIBIA and FIBULA at the KNEE JOINT.
A condition characterized by inactivity, decreased responsiveness to stimuli, and a tendency to maintain an immobile posture. The limbs tend to remain in whatever position they are placed (waxy flexibility). Catalepsy may be associated with PSYCHOTIC DISORDERS (e.g., SCHIZOPHRENIA, CATATONIC), nervous system drug toxicity, and other conditions.
Functional proteins that do not have unique, stable, folded, three-dimensional native structures or that possess non-ordered regions under physiological conditions. They are characterized by extraordinary structural flexibility and plasticity, which enable them to adopt different conformations in response to different stimuli or different interactions.
A joint is where two or more bones come together, like the knee, hip, elbow, or shoulder. Joints can be damaged by many types of injuries or diseases, including Arthritis - inflammation of a joint causes pain, stiffness, and swelling with ...
Pain is a feeling (sharp or dull) triggered in the nervous system which can be transient or constant. Pain can be specific to one area of the body eg back, abdomen or chest or more general all over the body eg muscles ache from the flu. Without pain ...
