LOS ANGELES • Former world No. 1 golfer Tiger Woods has said that he has finished a programme to help him manage his medications, following his arrest in May for impaired driving.

The 41-year-old American added that he would move forward with his next round of treatment to ease back pain and sleep issues with the help of his physician and relatives.

"I recently completed an out-of-state private intensive programme," the 14-time Major champion wrote on Monday on his Twitter account.

"I will continue to tackle this going forward with my doctors, family and friends.

"I am so very thankful for all of the support I've received."

He did not provide any details of the treatment or type of programme and did not say when he expected to return to golf.

He was arrested on May 29 near his Florida home for driving under the influence (DUI).

A breathalyser test showed no sign of alcohol but a police video showed him struggling to answer questions and he said later he did not realise how prescription drugs he was taking might interact.

"I want the public to know that alcohol was not involved," he added.

"What happened was an unexpected reaction to prescribed medications. I didn't realise the mix of medications had affected me so strongly."

He has had several surgeries to relieve lingering back pain and made a comeback in December in the Bahamas but has played only twice this year. He missed the cut at Torrey Pines and withdrew from the European Tour's Dubai Desert Classic in February.

In April, he announced he had undergone his fourth back operation since 2014 to ease back and leg pain and would miss the remainder of the season.

Woods, whose 79 career PGA Tour wins are three shy of Sam Snead's all-time record, has not won a Major title since the 2008 US Open and has not won any event since the 2013 World Golf Championships Bridgestone Invitational.

He was originally scheduled to appear in court today, but an arraignment for his DUI charge was pushed back to Aug 9.
