A study testing Mobility of the hamstrings muscles in people with Static Stretching and Dynamic Stretching, run by Luleå Tekniska Universitet.
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… Read more about this study

About this study
Official title: Effect of Dynamic Flexibility Training Versus Prolonged Static Stretching on Length of the Hamstrings Muscles and Patterns of Lumbar Flexion in Healthy Adults -a Randomized Controlled Trial
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Mobility of the hamstrings musclesBehavioural
| Study group | Role | What they receive |
|---|---|---|
| Dynamic streching | Experimental | Mobility training of the hamstrings muscles to be performed every day Receives: Behavioral: Mobility of the hamstrings muscles |
| Static stretching | Active comparator | Static stretching of the hamstrings muscles to be performed every day Receives: Behavioral: Mobility of the hamstrings muscles |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change of Range of motion of hip flexion
Hip flexion is performed in a standardised procedure and is measured in degrees.
Measured: Change from Baseline to after intervention (8 weeks), Change from Baseline to follow-up at 16 weeks
Change of Fingertip to floor distance
Distance from fingertip to floor test is performed in a standardised manner and is measured in centimeters
Measured: Change from Baseline to after intervention (8 weeks), Change from Baseline to follow-up at 16 weeks
Secondary outcomes (2)
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.
Measured: Change from Baseline to after intervention (8 weeks), Change from Baseline to follow-up at 16 weeks
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.
Measured: Change from Baseline to after intervention (8 weeks), Change from Baseline to follow-up at 16 weeks
