Effect of Progressive Muscle Relaxation Exercises Versus Pilates Exercises on Postnatal Low Back Pain

Not Applicable

Completed

• Conditions: Low Back Pain
• Interventions: Other: Progressive Muscle Relaxation Exercises; Other: Pilates Exercises

• Registration Number: NCT06284018
• Lead Sponsor: Cairo University

Brief Summary

This study was conducted to compare between the effect of progressive muscle relaxation exercises and the effect of pilates exercises on postnatal low back pain

Detailed Description

Ethical approval was obtained from the Institutional Review Board of the Faculty of Physical Therapy, Cairo University, before starting this study \[No: P.T.REC/012/003885\]. The study's protocol was explained in detail to each woman who signed an informed consent form before starting this study. This work adhered to the principles outlined in the Declaration of Helsinki for the ethical conduct of research involving human subjects. It was carried out from June till September 2023

Sample Size Calculation:

Based on a pilot study, sample size was calculated according to the significant difference in the value of mean difference (pretreatments - post treatment values) of pain pressure algometer between progressive muscle relaxation exercises (2.01 ± 0.39) and pilates exercises (2.90 ± 0.24) groups in unpaired t test, with α=0.05, power of 80%, and an effect size of 0.74. So a sample size of 30 patients/per group would be required and increased to 35 women to allow for a 15% dropout rate (GPower 301 http:www.psycho.uni-duesseldorf.de) Randomization of sample selection was achieved using closed envelop way. Classification of the sample by simple random way into two groups equal in number, by using sixty closed envelop, each thirty envelop contained a name of a group from the two groups (Group A) or (Group B) and asking each woman to choose one envelop from them, each woman attended to the group according the name of the group written in her envelop. After randomization, they were divided into two groups equal in number

Arm && Interventions

Group	Intervention	Description
intervention group1	Progressive Muscle Relaxation Exercises	Group A consisted of thirty postnatal women. They were treated by progressive muscle relaxation exercises three times per week for 4 weeks.
intervention group 2	Pilates Exercises	Group B consisted of thirty postnatal women. They were treated by pilates exercises three times per week for 4 weeks.

Primary Outcome Measures

Name	Time	Method
Pressure Algometer	period of treatment was 4 weeks	Assessment of pressure pain thresholds is a valid and reliable clinical tool to evaluate the subjective perception of pain in response to application of pressure in low back pain patient. Pressure algometry is used in manual therapy to objectively quantify the pressure pain thresholds and it was shown that a predictable variation exists across various spinal levels from cervical to lumbar levels. The examiner determined the main 4 points of assessment (5 cm lateral to the spinous process of L3 and L5 bilaterally), the force of PA was gradually increased at a rate of 1 kg/s, by silently counting seconds while increasing pressure, then the patient was asked to tell the examiner when the pressure became painful while the examiner applied the pressure on the assessment points

Secondary Outcome Measures

Name	Time	Method
Oswestry Disability Index	period of treatment was 4 weeks	ODI (P) is a reliable and valid instrument for measurement of disability related to low back pain in Punjabi population. It can be used both in research and clinical care settings in future Sandal, D., \[12\] . The 10 factors which constitute the ODI criteria for assessing patients' functional impairment are pain intensity, ease of personal care, lifting, working, sitting, standing, sleeping, sex life, social life and travelling. Each of the 10 questions was scored from 0 to 5, giving a maximum score of 50. The total score is then converted into a percentage by multiplying it by 2. Scores are stratified into severity: * 0-4: No disability; * 5-14: Mild disability; * 15-24: Moderate disability; * 25-34: Severe disability; * 35-50: Completely disabled
