Electrical Stimulation for Respiratory and Leg Muscles Impact on COPD Patients

It will be measured by dynamic gait index which includes eight items, walking on level surfaces, changing speeds, head turns in horizontal and vertical directions, walking and turning 180 degrees to stop, stepping over and around obstacles, and stair ascent and descent. Each item is scored on a scale of 0 to 3, with 3 indicating normal performance and 0 representing severe impairment. The best possible score on the DGI is a 24

It will be measured by spirometry to assess forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), and FEV1/FVC. The patient is instructed to take in a deep breath and then, as fast as he can, blow out all the air into a tube connected to a machine (spirometer). To get the "best" test result, the test is repeated three times.

It will be assessed by modified Borg dyspnea scale which uses a scale from 0 to 10, where 0 represents no dyspnea and 10 represents maximal dyspnea

Developed as a tool for assessing the severity Restless Legs Syndrome (RLS), the 10-item questionnaire asks respondents to use Likert-type ratings to indicate how acutely the disorder has affected them over the course of the past week. Questions can be divided into one of two categories: disorder symptoms (nature, intensity, and frequency) and their impact (sleep issues, disturbances in daily functioning, and resultant changes in mood) Rating scale and the RLS will be evaluated using the lower-limit clinical definition issued by the IRLSSG. Respondents with four "yes" were treated as having RLS. Respondents further performed the IRSSG Severity Scale with ten items to determine the severity of RLS symptoms. Patients were categorized into four classes of RLS ratings: mild (0~10), moderate (11~20), extreme (21~30), and very serious (31~40)

the pain will be evaluated by visual analogue scale (VAS) which assess pain intensity and progression. It is a straight horizontal line of fixed length, usually 100 mm. The ends are defined as the extreme limits of the parameter to be measured (symptom, pain, health) orientated from the left (worst) to the right (best).

It will be examined by pittsburgh sleep quality index (PSQI) which is a self-report questionnaire that assesses sleep quality over a 1-month time interval. It consisted of 19 items, the PSQI measures several different aspects of sleep, offering seven component scores and one composite score. The component scores consist of subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction.

Each item is weighted on a 0-3 interval scale. The global PSQI score is then calculated by totaling the seven component scores, providing an overall score ranging from 0 to 21, where lower scores denote a healthier sleep quality

Qol will be evaluated by The Chronic Respiratory Disease Questionnaire (CRQ) is a disease-specific health-related quality of life questionnaire. It was developed to measure the impact of Chronic Obstructive Pulmonary Disease (COPD) on a person's life. It consists of 20 items across four dimensions: dyspnea, fatigue, emotional function, and mastery. Items in each section are scored from 1 (most severe) to 7 (no impairment).
