Proprioceptive deficits can both predispose an individual to a greater risk for injury; impair sport performance. Stretching is commonly used as a technique for injury prevention in the clinical setting.
Objective: To study the effect of combined dynamic hamstring and quadriceps stretching on knee joint position sense.
Method: 15 healthy individuals randomly allocated in to three groups. Each group underwent dynamic quadriceps stretch, hamstring stretch and combined quadriceps & hamstring stretch. Shadow goniometer (SG) was the instrument used to measure Absolute angular error at 70o
Results: The analysis of pre and post stretch Absolute angular error within group reveals that it was statistically significant within combined group (p<.012), hamstring (p<.005) than quadriceps group (p>.378). However comparison between group revealed that, the analysis of variance between three group after intervention i.e. combined (2.47±1.60), Hamstring (1.93±1.44) and Quadriceps (4.80±3.30) was found to be statistically significant with (p <.003).
Conclusion: It is concluded that dynamic stretching of hamstrings or combined stretch (quadriceps and hamstring) has significant effect on improving knee JPS compared to quadriceps alone in healthy adults when measurements were taken in knee flexion movement.
