The SLE group exhibited significantly higher levels of fatigue and depression as well as worse sleep quality than the healthy control group. When attempting to manage/treat SLE, the factors dealing with aerobic capacity, muscular strength, mental instability, and functional incapacity need to be addressed.

Strength assessment of a voluntary isometric contraction of the quadriceps doesn't provide an adequate assessment of strength or endurance. As a result, this assessment doesn't reflect intended exercise capacity adequately. Also, functional incapacity could be related to poor proprioception and lack of balance. Future research needs to see if pain is a factor that could be contributing to the feeling of fatigue during sub-maximal exercise. The overall assessments conducted in this experiment were theoretically good, but external and internal factors that could precede or influence fatigue, strength, sleep, and depression were not controlled.
