Objective: Hamstring is one of the most critical muscle groups to maintain the gait cycle, but it is also one of the most commonly injured.The purpose of the research was to assess the comparative impacts of IASTM and dry needling on pain and functional status in participants with hamstring tightness.

Methods: A randomized clinical trial with 36 patients was carried out atgovernment hospital of Nankana Sahib. Based on pre-selected criteria, participants were recruited and categorized into 2 groups at random. First group gotdry needle therapy and second group was giventhe treatment with Instrument-Assisted Soft Tissue Mobilization (IASTM). Pain levels was evaluated using the Numeric Pain Rating Scale (NPRS), and functional activities was measured using the Lower Extremity Functional Scale (LEFS).

Results: A significant difference was found in mean of pre and post treatment values (p<0.05) of NPRS and LEFS in both groups. Across groups analyses revealed no significant disparity in NPRS and LEFS (p>0.05) after treatment of four weeks.
