Study summary

Postural syndrome describes a variety of conditions in which repetitive or continued bad posture over a long period of time causes pain and reduced function in the muscles and joints.

Improper posture can cause pain throughout the length of the spine from the neck to the pelvis. Modern sedentary style of living is one of the main reasons for postural abnormalities evident in modern society. The prolonged sitting hours required in most of the jobs, and educational setups can affect flexibility of soft tissues, especially two joint muscles. Bad posture while standing or walking, if left uncorrected, can worsen over time and lead to pain and dysfunction. Hamstring is a key component of flexibility in the human body and it is more prone to get tightened. Many reasons can lead to the development of hamstring tightness such as genetic predisposition, injury to muscle, and adaptive shortening due to some chronic condition. Short hamstring muscles, because of their attachments to the posterior leg and to the ischial tuberosity, may limit hip flexion ROM and induces posterior pelvic tilt and decreased lumbar lordosis, which can result in LBP The purpose of this study will be to find out the effects of stretching with and without pressure biofeedback unit (PBU) on hamstring muscle flexibility in patients with postural syndrome. The active knee extension (AKE) test will be used to determine the length of the hamstring muscles using a goniometer. A PBU will be used to maintain the anterior pelvic tilt position during active knee extension (AKE) test or stretching, by monitoring the pressure of airbag. Patients will be recruited into study by convenient sampling technique after that will be allocated to groups by simple random assignment. All participants will actively stretch three days per week for four weeks. After collecting data from defined study setting, data will be entered and analyzed by using Statistical Package for the Social Sciences (SPSS) for Windows software, version 25.

What researchers measure

Primary outcomes

  1. range of joint

    universal goniometer as range increase it shows betterment

    Time frame: 4 weeks

  2. pain of patient

    NPRS The Numerical Pain Rating Scale (NPRS) is a subjective measure in which individuals rate their pain on an eleven-point numerical scale. The scale is composed of 0 (no pain at all) to 10 (worst imaginable pain).

    Time frame: 4 weeks
