Brief summary

The superficial posterior line is one of the eight main fascial lines defined on the body. One of the important muscle groups on this line is the hamstring muscle group. Studies have shown that various stretching methods applied to the hamstring muscle group affect the cervical region both in terms of range of motion and posture. As a result of this study, it was shown that deep neck flexor endurance increased in women who applied the PNF hold-relax method.

Detailed description

The superficial posterior line is one of the eight main fascial lines defined on the body. One of the important muscle groups on this line is the hamstring muscle group. Studies have shown that various stretching methods applied to the hamstring muscle group affect the cervical region both in terms of range of motion and posture. Our aim in our study is to examine the effect of the proprioceptive neuromuscular stretching (PNF) method applied to the hamstring muscle group on the endura of the deep neck flexors based on these data.

Interventions

OTHERProprioceptive neuromuscular facilitation

The reason for choosing the proprioceptive neuromuscular facilitation technique is that it increases the hip flexion angle more than static stretching. Participants first lay down on the stretcher in a supine position. Then, the participant's lower extremity was lifted straight until the physiotherapist felt resistance. After reaching this position, the participant was asked to try to extend his lower extremity straight with half of his strength. After 10 seconds, the participant was given time to relax and after the participant relaxed, the lower extremity was brought to the new range of motion. This process was applied 3 times.
