The Acute Effects of Different Stretching Techniques

The flexibility of the hamstring muscles is very important and many stretching methods are applied on the hamstring muscles for reducing muscle resistance on movement. The objective of this study was to investigate the acute effects of static stretching and the Mulligan traction straight leg raise (TSLR) technique administered to the hamstring muscles on reducing its resistance to movement by using ultrasound elastography in healthy individuals.

About this study

The study will be included 22 healthy male volunteers. Static stretching will be administered to the hamstring muscles in the first group and the Mulligan TSLR technique will be administered on the same muscle in the second group. Active knee extension angles of the individuals will be evaluated by a digital goniometer and muscle elasticity will be assessed by ultrasound elastography.

Acute effects of Mulligan TSLR on reducing muscle resistance to movement will be evaluated by ultrasound elastography for the first time in this study. In our study, it was planned to examine the acute effects of static stretching and Mulligan TSLR techniques on reducing muscle resistance to movement by ultrasound elastography in healthy individuals with hamstring shortness.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Participants with short hamstring muscles (active knee extension angle below 70 degree),
  • Without knee, hip, ankle, or waist pathology,
  • Who had not undergone any surgery on the lower extremity were included in the study.

Exclusion criteria

  • Individuals with musculoskeletal, neurological, or vestibular problems,
  • Bone pathologies,
  • Joint laxity,
  • Diabetes,
  • Metabolic syndrome,
  • Arthritic or inflammatory problems were excluded.

Treatment and study plan

Static stretching

Behavioral

Static stretching exercise will be performed under the supervision of a physiotherapist as 30 seconds of stretching and 15 seconds of rest with 10 repetitions, and the individuals will be asked to participate in the exercise actively.

Mulligan TSLR technique

Behavioral

Mulligan TSLR will be applied by a physiotherapist in 3 repetitions with the patient in the supine position.

Primary outcomes

  1. The evaluation of muscle flexibility

    Time frame: Five minutes after the application

    The evaluation of muscle flexibility will be made using the ultrasound elastography method by a radiologist.

Secondary outcomes

  1. Range of motion (ROM)

    Time frame: Five minutes after the application

    Active knee extension angles of the individuals will be measured using a digital goniometer by a physiotherapist.
