Introduction: Prolapsed Intervertebral Disc (PIVD) is one of the most typical musculoskeletal conditions affecting the lumbosacral spine and is considered a leading primary reason for low back pain and sciatica. Altered spinal biomechanics, neural tension, and muscle spasm, which are considered to be the primary factors in PIVD, may result in hamstring tightness and shortness. Hamstring tightness is defined as the reduction in the extensibility of the hamstring muscle group, which includes the biceps femoris, semitendinosus, and semimembranosus muscles. This hamstring tightness leads to hamstring shortness due to inactivation for prolonged time. However, shortening of the hamstring muscles would affect the flexibility of the pelvis and the lumbar region during any physical activity, thereby changing the mechanical forces and causing unnecessary stress, leading to pain. The secondary effects on the musculature need to be considered while evaluating the prevalence in patients with PIVD.
Aim: To assess the prevalence of hamstring tightness and hamstring shortness among individuals diagnosed with PIVD.
Materials and Methods: The present cross-sectional study was undertaken among 120 participants aged between 18 to 80 years with lumber PIVD was conducted from September 2025 to February 2026 at Maharishi Markandeshwar Institute of Physiotherapy and Rehabilitation, Mullana, Ambala, Haryana, India. Participants were asked for their consent before undergoing the Finger to Toe Touch Test (FTTT) and Active Knee Extension Test (AKET) for measuring hamstring flexibility. Visual Analogue Scale (VAS) was used for measuring pain intensity. Participants were considered to have hamstring shortness if the AKET was >23.4° for females and >33.0° for males. Participants were considered to be tight if AKET was >20° and FTTT was >10 cm. Descriptive statistics were used for calculating prevalence.
Results: Among the participants, 61 were males and 59 females with a median age of 41 years {Interquartile Range (IQR) 32-52}. Hamstring tightness was more prevalent in males 31 (50.82), while hamstring shortness was higher in females 45 (76.27). Overall prevalence of hamstring shortness and tightness was 60% and 36.66%, respectively.
Conclusion: According to the findings of the present study hamstring tightness and shortness are common in individuals with PIVD and may contribute to associated musculoskeletal dysfunction.
