Abstract	Background: Hamstring flexibility is considered as a prerequisite for normal mobility and function as its inflexibility has been related with development of soft tissue and musculoskeletal injuries. There are reports of higher incidence of ‘Work-related Musculoskeletal Disorders’ (WMSD) in working women and majority of them have been linked to tight muscles, especially, hamstrings. Hence, need arises to find out simple yet efficacious therapeutic intervention that can counter the hamstring tightness and ameliorate its negative effects. Proprioceptive Neuromuscular Facilitation (PNF) stretching and Neural Mobilization (NM) techniques are coming up as promising methods to augment flexibility in athletes. However, effectiveness of these interventions needs to be examined in other population groups. Objective: To investigate and compare the effectiveness of PNF stretching with combined effects of PNF stretching and Neural Mobilization (NM) on the hamstring flexibility in working females. Materials and Methods: 24 females aged 25-40 years with hamstrings tightness as demonstrated by 20o loss in Active Knee Extension (AKE) and Straight Leg Raise (SLR) less than 70o were included in study and randomly allocated to two groups. Group A (n=12) received PNF stretching only while Group B (n=12) was administered PNF stretching followed by NM to hamstrings muscle. Both the groups received 20 intervention sessions, i.e. 5 days per week for a total period of 4 weeks. AKE and SLR were measured before and after 4 weeks of intervention. Results: The results revealed that hamstring flexibility significantly improved in both groups after 4 weeks of intervention. Further, between the group comparison demonstrated that non-significant differences existed in improvement scores of AKE (t=1.86,p=0.075) and SLR (t=1.51,p=0.14 ) indicating that both interventions were equally effective in improving hamstring flexibility in working women. Conclusion: Finding of present study revealed that neural mobilisation component when applied in combination with PNF stretching did not produced any additional benefits in terms of hamstring flexibility among working women..
