Abstract

This study examined whether massage and passive stretching reduced Delayed Onset Muscle Soreness (DOMS) and improved hamstring flexibility in Klinik Utama Satu Sehat Semarang patients. A quasi-experimental one-group pretest–posttest approach was employed with 20 purposively selected individuals. The VAS rated DOMS intensity and the Sit and Reach Test tested flexibility. The data was analysed using the Shapiro-Wilk test and paired sample t-test (α = 0.05). There was a substantial decrease in DOMS severity from 6.12 to 2.85 (p < 0.05) and an increase in hamstring flexibility from 23.40 to 30.60 cm (p < 0.05). Conclusion: Massage and passive stretching alleviate DOMS and increase hamstring flexibility.

Abstract

Adults are increasingly experiencing upper back muscle imbalances, particularly rhomboid muscle tightness, often due to prolonged sitting and poor posture. This study aimed to evaluate the effectiveness of a single passive stretching session in relieving rhomboid muscle tightness in adults. A one-group pretest-posttest quasi-experimental design was employed using pre-existing data from Klinik Satu Sehat Semarang, which included 13 adults aged 18 to 59 years. Each participant underwent a single passive stretching session, and measurements of shoulder movement and muscle tightness were taken before and after using a goniometer and the Visual Analog Scale (VAS). A paired t-test revealed a statistically significant reduction in muscle tightness (p = 0.004), with an average decrease of two VAS points. Additionally, shoulder retraction range of motion increased by an average of 6 degrees (p = 0.001).  Passive stretching of the rhomboid muscle effectively improves shoulder mobility and reduces upper back stiffness in adults within a single session, making it a practical method for addressing muscle problems caused by poor posture and applicable in rehabilitation and prevention programs.
