Dartitis: The condition where you try to throw a dart - but can't

Former darts champion Kevin Painter suffers from Dartitis

Former professional darts champion Kevin Painter has thrown arrows almost every day for 40 years.

Throughout his career he thrived under pressure, playing in the most prestigious competitions and taking home more than £900,000 in prize money.

But earlier this year, he went to throw a dart and it physically would not leave his hand.

"You're in shock, I stood there for ages. I just couldn't get my arm up to let go of the dart," he said.

Kevin was suffering from dartitis, a mental condition where the brain stops a player from being able to release a dart.

Finding a cure would become the 57-year-old's latest challenge.

"[Dartitis is] in the absence of any physical trauma, it's purely psychological," said Dr Linda Duffy, professor of psychology at Middlesex University.

From 1982 to 1987 she was ranked women's world number one and also experienced dartitis.

"I used to combat it with extra practice. It was heard of back in the day, but not many people spoke about it," she said.

Dartitis can affect all players, professional or amateur.

Jack Langston, a darts referee and online content creator, was 12 when he first experienced the condition.

"There was a little pause just before I threw the dart," he said.

It was barely noticeable at first but eventually it became so bad he would take 60 seconds to throw three darts.

By the age of 13, he was forced to quit and at the time, considered his darts career to be over.

"You're turning up and getting beat by people you know you should be beating," he said.

"It's so demoralising. It's a real mental struggle."

Every case is different, and there is no one single cause, but lots of players report it comes from a fear of missing.

"It's brought on by anxiety and stress," Kevin said.

"Where others have panic attacks, for me it manifested as dartitis."

After he first experienced the condition, Kevin was introduced to a hypnotherapist.

Chris O'Connor runs Eccleston Park Hypnotherapy, the official hypnotherapy partner of the Professional Darts Players Association (PDPA).

During his sessions, the patient lies on a sofa and is guided into a trance where they are then "hit with all the confidence work and the motivation work", Mr O'Connor said.

"It's all about getting them to visualise an area of their life they want to improve."

After eight sessions, it seemed Kevin's dartitis had been cured.

He thanked Mr O'Connor and said the treatment had worked, in a video posted to social media.

But two weeks later, during a televised match at the World Senior Darts tour, the condition returned.

"I was really, really disappointed," he said. "I thought it had gone."

Dr Duffy admitted she is unconvinced by hypnotherapy.

"I don't think it'll work - ever - because throwing darts is a conscious skill. So having therapy on your unconscious movements, I don't think is going to help it," she said.

Perhaps due to its name, players have a tendency to view dartitis as a problem unique to the sport which therefore demands unique solutions.

But Dr Duffy emphasises "it's just another cognitive disorder, so it should be treated that way".

She prefers to use cognitive behavioural therapy (CBT), where the player reframes dartitis as a challenge they need to overcome.

Unlike Kevin, Jack has managed to shake his dartitis and with lasting results.

In January, the 31-year-old decided to start throwing with his left hand.

"[It was] the biggest decision of my entire life playing darts," he said.

But it worked, and within three months he was winning matches at amateur tournaments.

Alongside his better performances, Jack found another benefit - he no longer needed to drink alcohol to play.

"I used to shake if I didn't have a beer I'd be so nervous," he said.

"If you'd have told me a year ago I'd play darts sober, I wouldn't have believed you."

To help aid his recovery, Kevin has also started to drink less.

"It's no secret everyone likes a drink when they play," he said.

"But you have to put the effort [into the treatment]. I like to go for a walk in the mornings to clear my head."

While reducing alcohol consumption is a welcome benefit, Dr Duffy is clear she does not think there is a link between drinking and dartitis.

"The underlying mechanisms that cause dartitis are the same things that cause any other anxiety disorder," she said.

Kevin plans to continue his hypnotherapy treatment, hoping this time the dartitis stays away for good.

"Everyone's been very supportive," he said.

"I've spoken to so many people who have it or have had it. I wouldn't have had those conversations if I didn't get dartitis."
