An interventional study of The hamstring eccentric exercises and The neurodynamic sliding technique in Hamstring Tightness, sponsored by King Saud University. Completed at 1 site in India. Open to female participants aged 18 Years to 25 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-11-05.

This randomized comparative trial evaluated the effects of a six-week, supervised intervention comparing eccentric exercise to the neurodynamic sliding technique in 42 sedentary young women with hamstring tightness. Both interventions were completed without adverse events and produced significant improvements in hamstring flexibility (active knee extension) and lower-limb strength. Although the eccentric exercise group achieved significantly greater strength gains and greater flexibility improvements over time compared to the neurodynamic sliding group, the overall between-group differences in flexibility across time points were not statistically significant and were confounded by baseline imbalances. Consequently, while both approaches are effective for this population, eccentric exercise demonstrated greater overall benefits, though the between-group flexibility advantages warrant cautious interpretation.

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

In the eccentric exercise group the participants performed a TheraBand-assisted eccentric hamstring exercise three times weekly for a total duration of 6 weeks.
Other: The hamstring eccentric exercises
In the neurodynamic sliding technique group the participants performed a a seated slump-based neurodynamic sliding sequence three times weekly for a total duration of 6 weeks.
Other: The neurodynamic sliding technique
To perform hamstring eccentric exercises in supine with the lower extremities fully extended, a 1-meter TheraBand was wrapped around the foot and held in both hands. Participants actively flexed the hip while resisting eccentrically with the hamstrings for about 5 seconds, then slowly extended the hip.
To perform the neurodynamic sliding technique, participants sat with a slouched posture and hands behind their backs, then alternated cervical extension with ankle dorsiflexion and knee extension, followed by cervical flexion with ankle plantarflexion and knee flexion.
Active Knee Extension Test
Participants lay supine with the hip and knee flexed to 90 degrees, actively extended the knee while maintaining hip position, and the popliteal angle was calculated as 180 degrees minus the measured knee extension angle, with lower values indicating greater flexibility. Normal Range for this outcome is 15 degrees - 25 degrees. Lower values indicate better outcome.
Time frame: This outcome was measured before the initiation of the 6-week intervention and at the end of the 6-week intervention.
Lower-limb strength
Participants stood on the platform of Back-Leg-Chest dynamometer, with slight knee flexion, grasped the handle at knee level, and performed a maximal isometric lift for three seconds. Normal ranges: 220 to 330 lbs. Higher values indicate better outcome.
Time frame: This outcome was measured before the initiation of the 6-week intervention and at the end of the 6-week intervention.
