About

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

Full 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
