Short-term effects of static stretching versus myofascial release on hamstring tightness and lower extremity function in sedentary IT professionals: a randomized controlled trial

Background Prolonged sedentary work is associated with hamstring tightness, reduced flexibility, and functional limitations among information technology (IT) professionals. Comparative evidence for static stretching and myofascial release (MFR) in this population remains limited.Objective To compare the short-term effects of static stretching and myofascial release on hamstring tightness and lower extremity function in sedentary IT professionals.Methods In this two-arm randomized controlled trial, 30 IT professionals were allocated to static stretching (n = 15) or MFR (n = 15). Both groups received stipulated treatment five times weekly for three weeks. Active knee extension range of motion (AKE-ROM) was the primary outcome measure, and the self-reported Lower Extremity Functional Scale (LEFS) was the secondary outcome measure. Outcomes assessments were performed at baseline and days 8, 15, and 22. Data were analyzed using linear mixed-effects models examining group, time, and group-by-time interaction effects, with Bonferroni-adjusted post hoc comparisons.Results Both interventions significantly improved AKE-ROM and self-reported LEFS over time (all p Conclusions Both interventions improved AKE-ROM and self-reported LEFS over the study period. Static stretching demonstrated statistically greater improvements in AKE-ROM; however, the magnitude of this difference was smaller than published minimal detectable change values, and its clinical importance remains uncertain. Given the absence of a control group and the short follow-up period, findings should be interpreted cautiously.Trial registration ClinicalTrials.gov NCT06586554; initial release date: 04/09/2024.
