Laser Acupuncture for Pulmonary Function Test and Quality of Life in COPD Patients

This clinical trial aims to evaluate the effectiveness and safety of laser acupuncture as an adjunct therapy in patients with chronic obstructive pulmonary disease (COPD). The main research questions are: * Does laser acupuncture, when combined with standard pharmacological treatment, improve lung function (measured by FEV1% and FEV1/FVC ratio) more than sham laser acupuncture after 4 weeks of therapy? * Does this combination also lead to better quality of life, as assessed by the COPD Assessment Test (CAT) and the St. George\'s Respiratory Questionnaire (SGRQ), compared to the control group, after 4 and 8 weeks? * Is there a correlation between lung function (FEV1%) and quality of life scores (CAT and SGRQ)? * Are there any significant adverse effects caused by laser acupuncture compared to sham treatment? Participants will: * Undergo spirometry and complete CAT and SGRQ questionnaires. * Receive either laser acupuncture or sham laser acupuncture sessions. * Return for follow-up assessments at 4 and 8 weeks.
