Effect of Manual Technique on Hamstring Flexibility
Condition: Muscle Tightness
Study type: Interventional

Summary: 
      This study will be a randomized clinical trial. the study will be conducted in Mubarak
      Hospital Sargodha. a sample size of 44 subjects will be taken. subjects will be divided into
      two groups using the lottery method. group 1 will be treated with Bowen technique along with
      heating pad and group 2 will be treated with sustained stretching technique along with
      heating pads thrice a week for 3 weeks. subjects will come after 1 month for follow up. the
      follow-up will show which technique is more effective in improving hamstring flexibility and
      range in healthy females. the outcome measures active knee extension test and sit and reach
      test will be used to check hamstring flexibility and range at baseline, post-treatment, and
      follow-up. data were analyzed using spss 26.
    

Detailed description: 
      hamstring muscles are responsible for hip and knee movement during walking, running,
      squatting, bending knees, and pelvis tilting. hamstring muscles function is to perform
      flexion at knee and hip extension. hamstring tightness is more common in females than males.
      once the hamstring were tightened ,incidence of low back pain rose to 15%.

      hamstring shortening occurred due to maintain same posture for prolong period of time,
      fatigue, sedentary life style, and poor body mechanics. hamstring tightness can disturb the
      biomechanics of low back and pelvis in each adolescents and adult. most of the individuals
      with hamstring tightness were asymptomatic. Throughout daily activities, nerves that
      innervate the hamstring muscle is exposed to constant pressure throughout sitting, standing
      can cause hamstring tightness.. Nerve adhesions inside the hamstring may alter neurodynamic
      inflicting abnormal machan-o-sensitivity of the nerve that will influence hamstring
      flexibility. This machan-o-sensitivity of the neural tissue could limit hamstring length in
      traditional healthy people. Shortened hamstrings amendment the curvature of the spine
      inflicting larger compression masses within the mesial curvatures and increase in intradiscal
      pressure and also the incidence of larger shear forces, thereby predisposing people to spinal
      issues various techniques were used to treat hamstring tightness. this study we compare the
      effects of Bowen technique and sustained stretching on hamstring flexibility in asymptomatic
      females.

      group 1 will be treated with Bowen technique .this is a soft tissue mobilization technique
      This medical care involves short mild rolling moves over the muscles, nerve, ligaments and
      tendons of flesh utilizing the hands, fingers and thumb. Sequence of receiving bilateral
      rolling moves over segments of the erector spinae from the lumber toward cervical spine,
      latissimus dorsi, the gluteal, the hamstring muscles proximally and distally, tensor facia
      Lata and a medial hip striated muscle move. Treatment will be given thrice a week for 3
      weeks. and treatment session will be 20minutes for each leg.

      group 2 will be treated with sustained stretching technique. Sustained stretching is most
      common and safest technique used for hamstring tightness. This sort of stretch is applied
      slowly and bit by bit at a comparatively constant force to avoid eliciting a inborn reflex.
      The resultant increase in muscle length is said to elastic behavior. Static stretch of thirty
      seconds at a frequency of 3 continual stretches per single session is ample to extend muscle
      length. treatment will be given thrice a week for 3 weeks. Treatment session will be 30
      seconds for each leg. both groups will come after 1 month for follow up. Outcome measure
      active knee test and sit and reach test will be used to check hamstring flexibility and range
      in asymptomatic females at baseline, post-treatment and follow up. the goal of this study is
      to improve hamstring flexibility in asymptomatic females.

      active knee extension test and sit and reach test will be used to check hamstring flexibility
      and range in subjects. these both tests have very high reliability and validity. There is a
      lack of evidence demonstrating the effects of Bowen technique and sustained stretching on
      hamstring flexibility. the purpose of this study is to compare the effects of both techniques
      to assess which technique has more clinical impact than other.

Intervention description(s): Bowen technique is a soft tissue mobilization technique. This medical care involves short mild rolling moves over the muscles, nerves, ligaments, and tendons of flesh utilizing the hands, fingers and thumb. Sequence of receiving bilateral rolling moves over segments of the erector spinae from the lumber toward cervical spine, latissimus dorsi, the gluteal, the hamstring muscles proximally and distally, tensor facia Lata and a medial hip striated muscle move.; static stretching is one of the most common and safest technique used for hamstring tightness. A static stretch is performed by inserting muscles at their greatest attainable length and holding that position for an amount of your time.
