Background and purpose: flexibility is defined as the ability of muscle to lengthen and allow one joint (or more than one joints) to move through a series of range of motion. Muscular flexibility is an important aspect of normal human function. Limited flexibility has been shown to affect a persons level of function as stated by Gurpreetkaur, Vol 7 2013 [1] poor hamstring flexibility, poor abdominal strength, increase levels of physical activity and work related postural stress leads to tight hamstring as stated by (Herting2006 , Jonhager 1994 and Cool 1984) [6]. This postural imbalance leads to low back pain. Low back pain (LBP) is a problem worldwide with a lifetime prevalence reported to be as high as 84% by World Health Organization (WHO) (Wilson et al, 2003) [8]. Hamstrings muscles are short are often reported in patients with low back pain. [14; 15,16,17]. Wingerden et al [18,19] proposed that hamstring tightness in individuals with low back pain would be the compensatory mechanisms for weak gluteal muscles.
