OBJECTIVE: To determine the amplitude of the electromyographic activity of trunk
muscles during Pilates exercises in women with and without chronic low back pain
(LBP). DESIGN: Case-control study. SETTING: University physical therapy clinic.
PARTICIPANTS: Women (N=60) divided into an LBP group and a control group.
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Amplitude of the
electromyographic activity (root mean square values) of the gluteus maximus and
external oblique muscles collected during 3 Pilates exercises: Shoulder Bridge
performed on the mat, and Hip Roll and Breathing performed in equipment. Pain
intensity was assessed in the LBP group. RESULTS: The amplitude of the
electromyographic activity was similar between groups (P>/=.05). For both groups,
the amplitude of the gluteus maximus was higher in the Shoulder Bridge exercise
compared with the Hip Roll with 2 springs (control group: mean difference
[MD]=.18; 95% confidence interval [CI], .05-.41; LBP group: MD=.29; 95% CI,
.16-.31) and the Breathing exercise (control group: MD=-.40; 95% CI, -.55 to
-.26; LBP group: MD=-.36; 95% CI, -.52 to -.20). The amplitude of the external
oblique muscle was higher in the Shoulder Bridge compared with the Hip Roll with
2 springs (control group: MD=.13; 95% CI, .05-.21; LBP group: MD=.18; 95% CI,
.03-.33). Pain intensity increased after exercises, but this increase was lower
for the mat exercises. CONCLUSIONS: Similar muscle activation between groups was
found. The findings suggest that mat exercises caused less pain and a greater
difference in the amplitude of muscle activation compared with the
equipment-based exercises.
