effects of schroth-based exercise on kyphosis angle, muscle strength, balance, pain, and quality of life in hyperkyphosis with chronic neck pain

Conditions: Postural Kyphosis; Chronic Neck Pain

Summary: the normal thoracic kyphosis angle of the spine is 20-40°, however, an angle of more than 40° is referred to as postural kyphosis, increased kyphosis or hyperkyphosis. although postural kyphosis negatively affects individuals' general health status, physical performance, and quality of life, there is still no standardized protocol for correcting the thoracic kyphosis angle. conservative treatment approaches such as postural training and exercises, manual therapy, postural corrective kinesiotaping, and orthotic use have been recommended for managing increased thoracic kyphosis. while numerous studies have demonstrated the effectiveness of three-dimensional exercise programs in the treatment of scoliosis, research examining their impact on kyphosis remains considerably limited.nevertheless, the potential of these exercises to promote neuromuscular reorganization suggests that they may be similarly effective in individuals with thoracic kyphosis. this randomized controlled trial aims to evaluate the effects of a schroth-based three-dimensional exercise program on kyphosis angle, trunk muscle strength, balance, pain, and quality of life in individuals with postural hyperkyphosis and chronic neck pain.

increasing thoracic kyphosis, spinal extensor muscle weakness, decreased spinal extension mobility, lumbo-pelvic pain, muscle activation and displacement of the scapula with changing traction angles have been associated with postural changes. it is evident that such alterations in posture have a biomechanical effect on the cervical and lumbar vertebrae. the presence of thoracic dysfunction has been documented in individuals experiencing chronic neck pain. increases in both the thoracic kyphosis angle and flexor posture have been demonstrated to result in anterior displacement of the central gravity line. displacement of the body's centre of gravity anteriorly has the potential to exert adverse effects on postural control.the association between postural changes and spinal extensor muscle weakness, increased kyphotic posture, decreased spinal extension mobility, lumbo-pelvic pain, muscle activation and displacement of the scapula with changing traction angles has been demonstrated. these postural changes have been demonstrated to exert a detrimental effect on postural stability, back pain, physical performance and quality of life. the present study was meticulously designed as a schroth-based three-dimensional exercise group and a control group, with a duration of eight weeks. the two groups will both undergo a programme comprising 20 sessions of electrotherapy and exercise, to be administered over a period of four weeks. subsequent to the completion of the fourth week of electrotherapy sessions, the exercise applications will be continued for a further four weeks by the physiotherapist responsible for the study, who will undertake the programme three days per week. the intervention will consist of a series of educational sessions focusing on the development of postural perception, with a particular emphasis on the identification of postural kyphosis and the adoption of optimal posture in daily living. these educational sessions will be administered to both groups. the training programme will be delivered in a practical manner by the physiotherapist. a brochure will be provided to patients, serving as a reference guide for the exercises and considerations.
