Abstract:
Background and Aim
Exersices for improving the accuracy of proprioception, as a risk factor in the most common site of injury, i.e. knee, and rehabilitation to prevent further injury and improving function, is required. The purpose of the current study was to investigate the effect of plyometric hopping and box jump for six weeks on the knee joint position of male individuals with ACL reconstruction.
Materials and Methods
A total of 40 males with ACL reconstruction (mean±SD; age: 27.88±1.62 year, weight: 79.9±10.28 kg, height: 1.77±0.05 meter) were objectively selected. Participants were randomly divided into three groups: hopping (n=14), box jump (n=13), and control group (n=13). Prior to and six weeks after the exercises (three sessions per week), at the same time and place, joint positions were recorded using a digital camera and the data was analysed using Auto CAD softwear. The control group did not perform any intervention program. Mixed repetead measure ANOVA was used for data analysis.
Results
The results showed significant improvement from pre-test to post-test in joint position at 45º (p=0.002) and 60º(p=0.046) in hopping group and at 45º (p=0.001) in box jump group. No significat improvement was observed in other angles (p>0.05). No differnces in the joint position was found between hopping and box jump training groups (P=1/001) either. But a significant difference was found between the two hopping and box jump groups and control group (P=0/001).
Conclusion
It can be concluded that hopping and box jump exercises are useful to improve propriocpetion at 45º among male individuals with ACL reconstruction. However, it seems that hopping exercise is more benfitial compared with box jump exercise in improving joint position at 60º.
