The purpose of this study is to contribute to the academic basis for the prevention and treatment of back pain for future lumbar disc disease patients by comparing and analyzing the effect of using or not using Pilates equipment on the muscle activity of lumbar disc disease patients and ordinary persons during Pilates Hundred preb and Swimming preb. METHODS: The subjects were 20 female with a mean age of 30-50. In order to measure muscle activity, the surface electromyography (sEMG) was used. Muscles activation were analyzed. RESULTS: All the rectus abdominis (RA), external (EO) and internal oblique (IO) abdominal muscles showed a higher activity in Mat than in Hundred preb using equipment, and especially IO showed a higher activity in ordinary people than in lumbar disc disease patients. All the gluteus medius (Gmed), gluteus maximus (Gmax) and lumbar erector spinae (LES) showed a higher activity in Mat than in Swimming preb using equipment, but there was no significant difference between ordinary people and lumbar disc disease patients. CONCLUSIONS: The muscle activity of all the muscles was found to be higher in ordinary people than in lumbar disc disease patients, and IO muscle showed a significant difference during Hundred, and both Hundred and Swimming preb motions showed a higher muscle activity in Mat. It is considered that abdominal (AB) muscle, RA, Gmed, Gmax and especially IO muscle and transversus abdominis (TrA) need to be strengthened in lumbar disc disease patients and education in Mat would be more effective.
