Effect of Osteopathic Technique on Respiratory Parameters and Pain in Thoracic Outlet Syndrome

Method Design This parallel, two-group, randomized controlled trial will use concealed allocation, blinding of outcome assessors and intention-to- treat analysis. People with TOS will enroll to 3-month, osteopathic technique (Group A) or traditional physical therapy program (Group B). The allocation order will be concealed by placing each random allocation in a sealed opaque envelope, which will be opened after the participant enrolled in the study. Thus, researchers and therapists will not know or decide which enrolling participant would receive which therapy. After an envelope was opened, the participant and the therapists who administered the interventions will became aware of that participant's allocated intervention. Outcomes were measured at baseline and after 3 months. In addition to ethics approval *******.

Participants The study was conducted in Outpatient clinics of Faculty of physical therapy, Horus University. The study population will be consisted of patients diagnosed, by physicians or neurologists, as previous cases of 'definite' TOS. To be eligible to participate, patients with TOS were required to be aged 30-35 years, be in a stable clinical condition and have a physical disability based on assessment. The exclusion criteria were Patients with surgery plan for TOS, those who underwent TOS surgeries, those with smoking history, traumatic cervical injuries, diabetes mellitus and/or malignancies.

Interventions Group A In addition to usual care from the treating physician or neurologist, participants will be prescribed a 3 months program. It will consist a 60 minute of traditional physical therapy program, three sessions/week in addition to 60-minute of Osteopathic technique, once per week.

The program included:

I- Postural correction through correction of:

• Forward head
• Protracted shoulders
• Depressed shoulder.

II- Strengthen ex to:

• Shoulder girdle elevators and retractors.
• Cervical and dorsal extensors
• raising arms to reach full flexion and elevation.

III- Restoration of normal mobility o Inhibition of muscle spasm especially scaleni and pectoral ms. by source of heat\& slow, sustain and self-stretching ex.

IV- Breathing ex: diaphragmatic breathing.

The Osteopathic technique included:

Patients will be positioned in a supine position. Osteopathic technique will consist of supoccibital release, soft tissue release of thoracic outlet, mobilization of cervical facet joints, stretching of scalene anterior, scalene medius, upper trapezius, and levator scapula, pectorals major and minor. Subsequently, cost vertebral and cost transverse joint mobilizations will be applied using rib elevation. Then, manipulation of the vertebrae the levels between C6 and T1 will be applied using thrust mobilization technique. Afterwards, mobilization of the first rib will be applied. Finally, mobilization of the upper cervical spine will be performed.

Group B In addition to usual care from the treating physician or neurologist, participants were prescribed a 60 minute, three times per week of traditional physical therapy program.

The program included:

I- Postural correction through correction of:

• Forward head
• Protracted shoulders
• Depressed shoulder.

II- Strengthen ex to:

• Shoulder girdle elevators and retractors.
• Cervical and dorsal extensors
• raising arms to reach full flexion and elevation. III- Restoration of normal mobility o Inhibition of muscle spasm especially scaleni and pectoral ms. by source of heat\& slow, sustain and self-stretching ex.

IV- Breathing ex: diaphragmatic breathing,.
