PETALING JAYA: National doubles coaching director Rexy Mainaky has urged badminton's major nations to push for changes to the Badminton World Federation's (BWF) medical regulations following Toh Ee Wei's injury ordeal at the Singapore Open.

Rexy's frustration resurfaced after the mixed doubles world champion was unable to receive what he felt was adequate treatment when she injured her left knee during her quarter-final match against India's Dhruv Kapila-Tanisha Crasto at Singapore Open last week.
