Could you check this please?

Hi,

Could you check the following please?

"For many years, the codes of professional ethics for rehabilitation have been written and enforced in many countries. There are many cultural, social, and religious differences in our country; however, that necessitate the redefinition of these codes. Similar codes are just used to clarify the minds of researchers and contributors to the research. These differences have created challenges that were investigated during interviews and group discussions."

Thanks!
