Kyphosis, a posture disorder, is excessive curvature of the thoracic area in the spine. In a healthy person, there is a normal kyphosis angulation in the thoracic and sacral areas in the sagittal plane. Since the sacral area is more stable, pathological conditions generally occur in the thoracic area.

Kyphosis causes a bowing of the back, which leads to a hunchback or slouching posture. Normal values for the thoracic kyphosis are between 20˚ and 40˚ of angulations. When the curve of the thoracic spine exceeds this, it is described as either a postural kyphosis or Scheuermann's kyphosis.

The study question is: Does kinesio taping have an effect on kyphosis and quality of life in adolescents?

The purpose of the study is to determine the effects of kinesio taping on:

• Kyphotic curve.
• Forward head posture.
• Quality of life in adolescents. Postural kyphosis is the most common type that causes slouching in thoracic curve can occur in young age, it can be called 'slouching' and is reversible by correcting muscular imbalances.

Adolescent's kyphosis curve appear by bad habitual postures due to a carry-over effect from temporary changes in posture during computer use and smart phones.

Forward head posture (FHP) is characterized that cervical spine is held in protracted position for prolonged duration, it can lead to alterations in head posture ultimately leading to poor posture which is thought to be a deviation from neutral or normal posture.

Failure of the head to align with the vertical axis of the body can lead to further malalignments in the body, namely, rounded shoulders and increased thoracic kyphosis, to compensate for the altered location of the LOG, leading to further impairments . A combination of all these postural deviations is often known as "slouched posture" or "slumped posture." The Kinesio taping method was applied to correct the alignment of weak muscles as well as facilitating joint motion as a result of the tape's recoiling qualities. It was designed to be the approximate thickness and elasticity of skin and be worn three to five days at a time.

Kinesio taping is a therapeutic tool used with increasing frequency within musculoskeletal rehabilitation and to maintain preferred body alignment. It is a complementary treatment and is designed to facilitate the body's natural healing, Process while allowing support and stability to 5 muscles and joints without restricting the body's range of motion.

Due to the lack of research area of kinesio taping on kyphosis in adolescents, So, the purpose of the study is to know impact of the Kinesio taping on kyphosis and quality of life in adolescents.
