Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Fatigue severity scale
The Fatigue Severity Scale (FSS) 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.

Experimental:Transcutanousvagus nerve stimulation plus aerobic exercise
EXPERIMENTALTranscutaneous vagus nerve stimulation (tVNS), combined with aerobic exercise. Stimulation will be applied to the left auricular concha for 20 minutes per session, three times per week for six weeks, using standardized settings (30 Hz frequency, 300 μs pulse width) at a tolerable, non-painful intensity. This will be followed by 40 minutes of aerobic exercises.

SHAM COMPARATORsham transcutaneous vagus nerve stimulation (tVNS) using the same device and electrode placement. They will also perform the same 40-minute aerobic exercise program.
Interventions
Transcutaneous auricular vagus nerve stimulation (taVNS) was administered exclusively with fixed stimulation parameters set at a frequency of 30 Hz and a pulse width of 300 μs.3times a week for 6 week. * Only spring-loaded clip electrodes were used for stimulation on the left ear. * an aerobic exercises designed to improve mobility, strength, and fatigue tolerance lasted 40 minutes and included treadmill, walking andcycling with moderate intensity (60-70% max HR and frequency 3 sessions per week * No additional therapies (e.g., resistance training, aquatic therapy, or medications) were included in the intervention.
