Clinical Trial Summary

Mobility training in the form of stretching and flexibility training of our skeletal muscle is a common exercise. However, the evidence are scare and there are only a few studies comparing the effect of prolonged static stretching (> 90 sec) and dynamic flexibility training as to which of these methods has the best length-enhancing effect over time. Further, in clinical practice concerning low back pain, the possibility of a thigh hamstrings muscles to affect movement control of the spine is often mentioned, a link not fully explored in a controlled condition. The purpose of this study is to compare the effect of eight weeks of dynamic flexibility training versus prolonged static stretching on mobility in the hamstring muscles in adults with reduced mobility in the muscles at the back of the thigh. The aim is also to compare the sustained effect of flexibility training between the two groups, eight weeks after completion of the intervention. Furthermore, the aim is to explore how different forms of flexibility training affects movement patterns of the lumbar spine in adult persons with reduced mobility in the hamstrings.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change of Range of motion of hip flexion	Hip flexion is performed in a standardised procedure and is measured in degrees.	Change from Baseline to after intervention (8 weeks), Change from Baseline to follow-up at 16 weeks
Primary	Change of Fingertip to floor distance	Distance from fingertip to floor test is performed in a standardised manner and is measured in centimeters	Change from Baseline to after intervention (8 weeks), Change from Baseline to follow-up at 16 weeks
Secondary	Change in Waiters bow	Waiters bow is a test of movement controll of the lumbar spine and is measured a if movement is performed correctly or not.	Change from Baseline to after intervention (8 weeks), Change from Baseline to follow-up at 16 weeks
Secondary	Change in Sitting bilateral knee extension	Sitting bilateral knee extension is a test of movement controll of the lumbar spine and is measured a if movement is performed correctly or not.	Change from Baseline to after intervention (8 weeks), Change from Baseline to follow-up at 16 weeks
