50female patients diagnosed with systemic lupus erythematosus according to the 2010 Revised American College of Rheumatology (ACR). Their age will range from 35 to 55 years. The participants will be selected from one major healthcare institutions: Al Kaser Al Ayni Teaching hospital, will be randomly equally distributed into two groups. Group A :(Treatment Group): This group includes 25 patients diagnosed with systemic lupus erythematosus according to the 2010 Revised American College of Rheumatology (ACR),and will receive transcutaneous vagus nerve stimulation (tVNS), combined with aerobic exercise alongside medical treatment. Patients will receive 3 sessions per week for 6 weeks, the time of session is 45 - 60 min according to patient ability. Group B :( Control Group) This group includes 25 patients diagnosed with systemic lupus erythematosus according to the 2010 Revised American College of Rheumatology (ACR)and will receive sham transcutaneous vagus nerve stimulation (tVNS) using the same device and electrode placement. They will also perform the same 40-minute aerobic exercise program alongside medical treatment. Patients will receive 3 sessions per week for 6 weeks.
1)Subjects: 50female patients diagnosed with systemic lupus erythematosus according to the 2010 Revised American College of Rheumatology (ACR). Their age will range from 35 to 55 years.

Measurement equipment: • Fatigue severity scale: is a widely used self-report questionnaire designed to assess the impact of fatigue on daily functioning. It consists of nine statements rated on a 7-point Likert scale, with higher scores indicating greater fatigue severity. The FSS has demonstrated strong psychometric properties in patients with systemic lupus erythematosus (SLE), including excellent internal consistency (Cronbach's α \> 0.90) and good test-retest reliability (ICC = 0.84-0.89). The Arabic version of the FSS has been validated in multiple studies and has shown comparable reliability and construct validity to the original version. For example, Al-Sobayel et al. (2016) reported a Cronbach's α of 0.93 for the Arabic FSS in a population of Arabic-speaking patients with chronic diseases, including SLE. This makes the Arabic FSS a culturally appropriate and psychometrically sound instrument for assessing fatigue in Arabic-speaking populations. Six-Minute Walk Test (6MWT) is a sub-maximal exercise test that measures the distance a person can walk as far as possible in six minutes along a flat, hard surface. It is used to assess functional exercise capacity, endurance, and the integrated global response of many systems: pulmonary and cardiac function, circulation, peripheral circulation, neuromuscular function, The test can show performance fatigability when there is a decline in the individual's walking speed or distance over time (for instance, comparing the first minute of walking vs the last minute. Borg Rating of Perceived Exertion (RPE) ("Borg Test") is a subjective scale developed by Gunnar Borg, used to gauge how hard someone feels they are working during physical activity. It captures feelings of exertion, breathlessness, muscle fatigue, heart rate
