Murray was forced to miss the French Open and Wimbledon

He said: "It's time to go back out on the court and start giving 100%. I feel confident that I can do that."

The British number one revealed he had consulted a sports psychologist to help with the mental side of his recovery.

"I wouldn't say it was totally mental, but I just needed to work on that one shot and get the confidence back where I feel like I can hit it 100% again."

Interview: British number one Andy Murray

Murray is seeded 19th for the US Open and faces Uruguyan qualifier Pablo Cuevas in the first round on the Grandstand court on Monday.

The 20-year-old Scot suffered a right wrist tendon injury in May at the Hamburg Masters and has lost two of three matches since making his comeback.

We are hoping every day will get a bit better and hopefully he will be able to work his way into the tournament Andy Murray's coach Brad Gilbert

But he said: "I feel much better now than I did 10 days ago. I've got confidence back in my shot. I've played really well in practice, hitting the ball much harder.

"This is one of the hardest things I've had (to deal with) in my career, but I'm looking forward to getting back onto the court and getting into it.

"I might take a set, maybe a couple matches, before I'm hitting it absolutely perfect again, but I'm playing much better than I was before Cincinnati and Montreal."

Murray has reached the fourth round of his past three Grand Slam starts, including last year's US Open, but he is not looking too far ahead.

"I haven't even looked at my draw," he said. "It's the first time I've not seen who my second or third round opponent is. I'm trying to focus on one match at a time."

Murray's coach Brad Gilbert is also pleased with his charge's recent progress.

"The last couple of days we have had our best practice in a long time," Gilbert told BBC Radio 5live.

"We are hoping every day will get a bit better and hopefully he will be able to work his way into the tournament.

"The pain is gone and now it's about muscle memory and getting back out there and getting back into a good daily routine of what we had before.

"Andy is feeling good, nothing is bothering him and now it's not about the injuries, it's about the tennis, which is much more important."
