The purpose of this study is to evaluate the effect of low-power laser therapy on pain intensity and functional outcomes in patients diagnosed with Thoracic Outlet Syndrome (TOS). Participants will be randomly assigned to either receive the active laser therapy combined with a physical therapy program or a control group. The study aims to determine if adding laser therapy provides better relief and improves daily physical functions compared to conventional treatment alone.
Age
Age between 35-50 years.
Clinically diagnosed with Thoracic Outlet Syndrome (TOS) by a physician based on standard diagnostic criteria.
Presence of neurogenic symptoms such as pain, paraesthesia, numbness, or --
History of cervical disc herniation or cervical radiculopathy.
Previous surgical intervention in the cervical or thoracic outlet region.
Severe cardiovascular or systemic diseases that may interfere with treatment. --Pacemakers or other implanted electronic devices.
Skin conditions or infections in the treatment area.
Parallel
Low level laser therapy
Device"Patients will receive low-level laser therapy using a Gallium-Aluminum-Arsenide (GaAlAs) laser diode. Wavelength: 850nm, Power: 100mW. It will be applied to specific trigger points in the neck and shoulder area for 5 minutes per session, 3 times per week for 4 weeks."
Therapeutic Ultrasound
Device"Pulsed therapeutic ultrasound applied to the symptomatic area. Frequency: 1 MHz, Intensity: 1.5 W/cm², Duty cycle: 20%. The treatment will be applied for 5-8 minutes per session."
Physical Therapy Exercises
BehavioralA supervised physical therapy program focusing on stretching and strengthening exercises for the neck and shoulder girdle. This includes stretching of the scalene and pectoralis minor muscles, as well as strengthening of the middle and lower trapezius and serratus anterior. Each session lasts 30 minutes, twice per week for 8 weeks.
Sham Laser Therapy
Device"The same laser device will be used as in the experimental group, but without delivering any active laser energy. The device will be applied to the same points for the same duration to ensure blinding of the participants."
Pressure Pain Threshold (PPT)
The minimum pressure at which a stimulus is perceived as painful, measured using a digital pressure algometer at specific trigger points. The device measures the pressure in kilograms per square centimeter (kg/cm²).
