Pilates in Women With Chronic Low Back Pain

February 21, 2022 updated by: Marco Romagnoli, University of Valencia

Effect of a Pilates Exercise Program on the Flexion-relaxation Rate in Women With Chronic

The purpose of this study is to evaluate the effect of a Pilates exercise program (PEP) on the flexo-relaxation ratio (FRR) of the erector spinae (ES) muscle during standing maximal trunk flexion/extension in women with chronic low-back pain (LBP). A secondary goal is to investigate the effect of PEP on full trunk flexion ROM (TFRoM), pain intensity and functional capacity and analyse their relationship with the FRR.

Detailed Description

Purpose: To evaluate the effect of a Pilates exercise program (PEP) on the flexo-relaxation ratio (FRR) of the erector spinae (ES) muscle during standing maximal trunk flexion/extension in women with chronic low-back pain (LBP). A secondary goal was to investigate the effect of PEP on full trunk flexion ROM (TFRoM), pain intensity and functional capacity and analyse their relationship with the FRR. Material and methods: Thirty women with chronic LPB were randomly assigned to either PEP (EG, n=15) or control group (CG=15). EG followed an 8-week PEP while no specific intervention was carried out on the controls. Before and after this period all variables were recorded.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

45 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Experimental: EG: Exercise Group
Pilates exercise program (1 h x 2 sessions per week x 2 months)
Other: Pilates exercise program
The Pilates Exercise Program (PEP) (1 h x 2 sessions per week x 2 months) was delivered by one Pilates professional (with a mean of 6.5 years of experience in Pilates). The PEP carried out by Pilates instructor has been published in a previous study [31]. The exercises focused on core stability, posture, breathing, flexibility, strength, and muscle control, being the active awareness of the use of trunk muscles to stabilize the pelvic-lumbar region the main approach. The exercises performed were: the hundred, the rolled up, single leg circles with bent leg, spine stretch, rolling like a ball and single leg stretch. Each exercise was performed as follows: 4 repetitions of 30 seconds with 2 minutes of recovery between repetitions. In order to complete the 60 minutes session two exercises: the "superman" and the double leg bridge were added to the mentioned PEP.
Other Names:
  • Core strength exercise program

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
FRR was calculated by dividing the maximal EMG amplitude during flexion by the minimum EMG amplitude at full flexion. The mean of the 3 trials performed was used to determine the FRR for each muscle for each subject.
Time Frame: 2 months
A lower FRR indicated a greater state of muscle relaxation. Asymmetry in muscle activity between both (right and left) ES muscles was calculated as their mean difference in RMS in the three flexion-extension tasks. Asymmetry in the FRR was calculated as the absolute difference between FRR of the right and left ES muscles.
2 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Full TFRoM was calculated as the average TFRoM from the three flexion-extension tasks.
Time Frame: 2 months
To obtain the full trunk flexion ROM (TFRoM), the angular position of the inertial EMG sensor (attached with a kinesio-tape at T3 vertebrae) was measured from the start to the end of the flexion movement.
2 months
The version adapted to the Spanish population of the Low Back Outcome Score (LBOS) questionnaire was used to measure self-reported functional capacity.
Time Frame: 2 months
LBOS was measured at pre-intervention (T0) and pos-intervention (T8).
2 months
A 10-cm Visual Analog Scale (VAS) was used to evaluate pain intensity
Time Frame: 2 months
VAS was measured at pre-intervention (T0) and pos-intervention (T8).
