About this study

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

Treatment and study plan

Progressive Muscle Relaxation Exercises

Other
  • Focus on the targeted muscle group.
  • Take a slow, deep breath while squeezing on muscle group as hard as she can (not to the point of strain). Keep the muscle tensed for 5 seconds.

Pilates exercises

Other

Pilates exercise program consisted of floor exercises on a rubber mat, including the following exercises: a- Pelvic Curl. b- Single-Leg Lift. c- Chest Lift. d- Supine Spine Twist. e- Basic Back Extension.

Primary outcomes

  1. Pressure Algometer

    Time frame: 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 outcomes

  1. Oswestry Disability Index

    Time frame: 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
