The 19-year-old made her grand slam breakthrough in New York 12 months ago with wins over Kim Clijsters and Li Na to reach the fourth round.
She repeated the feat at Wimbledon this summer but suffered a wrist injury warming up for her first match in Toronto earlier this month.
The diagnosis was a tear in the sheath around the tendon in her right wrist, which forced her out of Toronto and her next two tournaments in Cincinnati and New Haven.
Robson's only matches since Wimbledon came at a tournament in Carlsbad last month, where she lost heavily to Petra Kvitova in the second round, but she is encouraged by how the injury has reacted to a cortisone injection.
She said: "I hit one backhand and I felt it go. It's never happened to me before like that. It was a bit of a weird one but stuff happens.
"We'll see how it is when I play but I'm pretty happy with how my rehab has gone. It's still going to be taped but I'm hoping it will turn out well.
"I hit points for the first time two days ago and I was pretty happy.
"It's on my non-dominant hand so I've still been able to practise forehands, serves and volleys. I've been on a mini training block in Florida at Bolletieri's (Academy) so it's been fine."
Robson certainly has more expectation on her shoulders than when she arrived at Flushing Meadows last year.
The teenager's talent had never been in doubt but her eye-catching run, which was eventually ended by then reigning champion Sam Stosur, made headlines around the world.
"I had a couple of big wins," said Robson. "It really gave me a lot of confidence going into other matches against top players, knowing I can beat them.
"I felt like I was playing really well for the rest of the year. It ended up being a really long season so I was exhausted at the end of it. But this year I feel a lot more rested coming into the tournament."
Robson has climbed steadily up the rankings since and, helped by her Wimbledon exploits, is seeded here for the first time at a grand slam.
At number 30, two places above her ranking, she is the first British woman to be seeded in a grand slam singles tournament since Jo Durie at the Australian Open in 1987.
The Londoner, who plays Spain's Lourdes Dominguez Lino in round one, insists not too much has changed, and she is certainly not about to let her new status go to her head.
She said: "I'm on the show practice courts this year, which is a lot nicer than P97 back in the park. That's pretty much the only difference. I'm staying at the same hotel and feel the same going into the tournament I think.
"I managed to get a hit on Armstrong today [Friday] and I played two matches on there last year so I like that court.
"I think (the seeding) only really makes a difference when you're at the tournament if you're top 16. Top 32 is still borderline. On my badge I'm still parking lot E or F, so it's not quite the same as parking lot A."
For a week at Wimbledon, Robson was almost as big a star attraction as Andy Murray, something she did not appear to enjoy too much.
Manhattan allows for a lot more anonymity, although not among One Direction fans it transpires.
Robson is a fan of the band and was the envy of millions of teenage girls during Wimbledon when several of its members sent good luck messages to her on Twitter.
Robson was amused that she had gained thousands of followers who did not know who she was, but it seems they have been learning.
She said: "I've had a couple of random looks walking around Manhattan. They must be British tourists. They don't really say hi, they just stare, which is a bit awkward.
"Then we were walking past the queue for the One Direction concert and there was a couple of hundred girls camped out. Some of them had been there for five days already. I'm not sure where their parents are.
"A couple of them were like, 'Oh my God you're the one that Harry tweeted'. I don't think they know my name or anything."
