To find the effect of conventional treatment on hamstring’s pressure pain threshold, USG, and strength in recreational football players with history of hamstring injury. To compare the efficacy of conventional therapy with and without IASTM in recreational football players with a history of hamstring injuries. METHODS: A randomized control trial. includes two groups (A and B), with a total of 30 patients randomized into 15 in each group, with experimental group A (IASTM) and control group B (Nordic protocol). Knee Range, AKE, SLHB TEST, VAS, and TAMPA scales were used as outcome measures for pre and post therapy for two weeks, with six sessions provided. RESULT: Data were input into Microsoft Excel, imported into Statistical Package for Social Sciences (SPSS) version 25, and analyzed with SPSS. The data was examined using descriptive and inferential statistics. Data are displayed as tables and graphs. Histograms and QQ plots were used to assess for normality in the data. The distribution is not normal, and the sample size for each group is fewer than 30. As a result, non-parametric tests were utilized. The data showed significant results for both the group(A&B) but Group A was highly significant than Group B. CONCLUSION: Finally, both IASTM and stretching have significant use in rehabilitation and sports performance enhancement. Understanding each modality's specific benefits, limitations, and appropriate uses is critical. Ultimately, the efficacy of treatment is determined by the individual's particular requirements, the practitioner's experience, and the incorporation of evidence-based methods into a holistic rehabilitation plan.In conclusion, IASTM combined with strengthening cryotherapy and warming outperforms stretching, strengthening, cryotherapy, and warmup alone
