简要总结
The purpose of this study is to find out if individuals with tight hamstring muscles who receive dry needling in addition to a standard stretching exercise program, show an improvement in hamstring tightness and function compared to individuals with tight hamstrings who receive either sham dry needling or no needling (blunt needle) in addition to a standard stretching program.
详细描述
Tightness of the hamstring muscles is a risk factor for injury. Currently, there is no data on the effect of dry needling on hamstring extensibility or functional performance measures among asymptomatic individuals with hamstring muscle tightness. The investigator wants to assess if individuals with tight hamstring muscles who receive dry needling in addition to a standard stretching exercise program, exhibit reduced hamstring tightness and improved functional performance compared to individuals with tight hamstrings who receive either sham dry needling or no needling (blunt needle) in addition to a standard stretching program.

结局指标
主要结局
Change in unilateral hop for distance test scores
时间窗: Baseline, at 5 weeks from baseline
The functional performance of the hamstring muscles will be assessed by using the unilateral hop for distance test. The subjects will be instructed to stand on the leg to be tested and hop and land on the same limb. The distance hopped, measured at the level of the great toe, will be measured (centimeters). Scores will be recorded as absolute distance (in centimeters). An increase in the score (distance covered) from baseline to 5 weeks from baseline indicates better functional performance of the hamstrings.
Change in crossover hop for distance tests scores
时间窗: Baseline, at 5 weeks from baseline
The functional performance of the hamstring muscles will be assessed by using the crossover hop for distance test. The subjects will be instructed to hop forward 3 times while alternately crossing over a marking. The total distance hopped forward will be recorded. The heel of the hop leg will be used to determine the length of the jump. Crossover hop limb symmetry index (LSI) scores for knee function within normal ranges are generally greater than 95%. An increase in the crossover hop limb symmetry index (LSI) from baseline to 5 weeks from baseline indicates better functional performance of the hamstrings.
Change in hamstring muscle extensibility
时间窗: Baseline, at 5 weeks from baseline
Bilateral 90/90 hamstring muscle extensibility passive range of motion (PROM) measurements will be assessed using a goniometer. The goniometer measures the angle of the joint at both extremes of the range of motion (ROM). An increase in the passive range of motion (PROM) indicates increased hamstring muscle extensibility.
次要结局
- Change in dynamometry pressure readings(Baseline, at 5 weeks from baseline)
