After a promising opening-half of the season the Royals have slumped in recent weeks and have not won just once since the end of November. The bad run culminated in an atrocious performance at home to Leicester on Tuesday.
Speaking to the Reading Evening Post, Parkinson said: "There is only one way to get out of the rut like this and that is to roll up your sleeves and get back to basics by working hard and making yourselves hard to beat."
In his advancing years Parky is starting to get involved with a lot more coaching as he sees his chances of first team football limited.
The 35-year-old does not believe the sides good run of form in the autumn was down to the loan signing of Matthew Upson, who recently completed a move to Birmingham.
During Upson's time at the club the team conceded just five goals in fourteen games - a run that has largely been put down to the defender's presence in the side.
Parky added: "People go on about Matthew - and he did play a big part in our run - but other players were on also on top of their game.
"In recent games we've missed chances and, although we've not played badly, confidence has taken a knock. Leicester were a very strong side and confidence did look low. Now is the time to get back to what we were doing, working hard. If we get a result tomorrow then we’ll be right back in the play-offs."
