Your hands know where the buttons are and how to rotate the instrument."Image copyrightGetty ImagesFor Rajin Chowdhury, a registrar in anaesthetic and intensive care at Sheffield Teaching Hospital, gaming has helped make him "more dextrous".Video games, he said, improved hand-eye coordination, and many procedures are performed remotely through looking at a screen."For example in an appendicectomy, because of the way the camera is inserted in the abdomen, when you move it down [in the body] you move it up on the image.

When I want to move right you have to move it left.

"It's not intuitive."'Texters react faster'Physiotherapist Ashley James said there is "very, very little evidence" to suggest the widespread use of smartphones by students affects their manual dexterity."There's not that research out there," he said.

"I'm not saying he [Professor Kneebone] doesn't have a point, but the likelihood is the authority and certainty of which he speaks is probably not based on fact or any evidence."Mr James pointed to a study of 100 medical students, half of whom were frequent mobile phone texters, and half light users."The researchers didn't find anything different in terms of dexterity," says Mr James.

"But another thing they tested in that study was reaction time.

"Mobile phone frequent texters had improved reaction time."He added: "It's just one small study.

I wouldn't hang my hat on it but I wouldn't be as forthright on my conclusion as the surgeon is."'Skills can be taught'One consultant surgeon in Leeds tweeted a story he was told of how a junior doctor got the job done during an operation, citing his Nintendo skills as a help.Meanwhile Susan Hill, vice president of the Royal College of Surgeons, said: "I have not noticed any great difference in the dexterity of the medical students or junior doctors I come into contact with, when compared to other generations.

"In fact, I can recall finding some surgical techniques extremely difficult to master myself even though I trained well before the IT revolution," she said."Although it may be useful for a surgeon to be naturally dexterous, the skills required to operate can be taught.

Much of surgical training is about practising skills such as cutting and sewing over and over until they are perfected."It's also worth recognising that some of the skills individuals pick up from their time on screen can be useful to their work as surgeons.

We're already seeing the beginnings of a future where a surgeon's ability to interact with technology, be that surgical robots or augmented reality, will become increasingly important."Practice makes perfectProfessor Steve Wigmore, a professor of surgery from the University of Edinburgh, said research is showing that playing computer games "is a good warm up" to performing keyhole, or laparoscopic surgery."I think the quality of the trainees is down to the quality of the training," he said.NHS surgeon and surgery professor Peter Brennan is the chairman of the MRCS exam for the UK and Ireland - the exam which junior doctors need to pass to become surgeons.

He said: "We are not going to let people pass that exam if we don't think they have the skills".And he added medical students who want to become surgeons often may choose that career path because they are "good with their hands".Many surgeons said practice is one of the top ways to improve their stitching and suturing skills - a rule which applies for both the current medical students - and older generations.As surgeon Mr Froghi joked, as the doctors of today get older, "do you think gardening will contribute to the acquisition and maintenance of new skills"
