About this study
Official title: Comparison Between Dynamic Oscillatory Stretch Technique and Static Stretching In Reduced Hamstring Flexibility in Healthy Population: A Single Blind Randomized Control Trial
This study compared the effects of dynamic oscillatory stretch technique (DOS) and static stretching (SS) technique in order to improve hamstring extensibility in healthy individuals with asymptomatic hamstring tightness. Half of study participants received DOS whereas other half received static stretching technique.
Read the detailed description
This was a single blind randomized control trial conducted at District Head Quarter teaching hospital Sargodha, Sargodha institute of health sciences Sargodha, Sadiq hospital Sargodha (march 2018-June 2018). Sample size of 83 individuals was calculated through Open Epi tool version 3 with 95 % confidence interval (CI), and power 80%. 83 individuals were screened out on the basis of inclusion and exclusion criteria. Individuals of this selected population were randomly allocated as 42 individuals in Dynamic Oscillatory Stretch(DOS) group and 41 individuals in Static Stretching(SS) group by sealed envelope method.
After the application of hot pack treatment of 7-10 minutes to both groups dynamic oscillatory stretch technique (30 repetitions each of 2 seconds stretch duration in one session) was applied to DOS group and SS stretching (2 repetitions each of 30 seconds in one session) was applied to SS group.
Assessment was done at baseline, immediate post-intervention levels (immediately) and post-intervention level after 1 hour. At baseline and immediately post-intervention level there was no dropout but after 1 hour post-intervention level there were two dropouts from DOS group and 1 dropout from SS group. 40 individuals were analyzed in each DOS and SS group. Data analysis was done through Statistical Package of Social Sciences(SPSS) version 20. Normality of different variables was assessed. Shapiro-Wilk test provided the basis for normality distribution of data.

What is being measured
The primary outcome is the main question the study is designed to answer.
Active Straight Leg Raise Test(ASLR) Immediate effect
Changes from baseline Active Straight Leg Raise Test(ASLR) was conducted with the participants in supine lying with both lower limbs initially extended. Then patient actively lifted the leg to be tested at hip joint while stabilizing the leg opposite to that of the testing side by using a stabilization belt. Knee on testing side was essentially sustained in full extension throughout the full testing range. Universal goniometer was used to measure range of motion available at hip joint.
Cut off score for the SLR to indicate hamstring tightness is 80 degrees. Therefore, values of SLR below 80 degrees was considered as hamstring tightness. Assessment was done Immediate after giving intervention(10 minutes).
Measured: 10 minutes

Measured: 1 hour
Active Knee Extension Test (AKE) immediate effect
Changes from Baseline Active knee extension test (AKE), is used to assess hamstring length. It was performed while the participant was in supine lying and involved leg was in 90 degree hip flexion. then participant was asked to extend the knee. For hamstring tightness cut off score AKE angle is 160°. Therefore normal individuals with angle < 160° were considered as individuals with hamstring tightness.Its reliability is 0.94.Assessment was done Immediate after giving intervention(10 minutes).
Measured: 10 minutes

Assessment was done after 1 hour of intervention.
Measured: 1 hour
Sit and Reach Test (SRT) Immediate effects
Changes from Baseline Sit and reach test (SRT) is most commonly employed test to measure hamstring flexibility. This tool is used to measure range of hamstring muscle at knee joint.Each participant was instructed to sits on a couch in long sitting position. participants were seated with elongated legs, with hip flexed to 90 degrees and knees were fully extended and the ankles were in relaxed plantar flexion. A measuring ruler/tape was placed,between the feet with 38 cm score was marked tangent to the sole of the feet. Subjects were asked to reach forward with hands one above the other and palms of the hands facing down, while attempting to touch fingertips to toes or as far beyond on measuring tape while keeping the knees straight. Assessment was done Immediate after giving intervention(10 minutes).

Numeric Pain Rating Scale (NPRS) Immediate effects
Changes from Baseline Numeric pain scale (NPRS) was used to assess pain intensity. it was used to assess the tolerance ability of individuals for pain produced at the end of passive straight leg raise (PSLR) test.It ranges from 0-10. 0 means No pain and 10 means severe pain. Assessment was done after 10 minutes of intervention.
Measured: 10 minutes

The record says: finished, as of the sponsor's last update on 8 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Pakistan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Active Straight Leg Raise Test(ASLR) Immediate effect (time frame: 10 minutes). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03885557, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
