Back still bothering Henry
The Gunners' leading scorer had looked a shadow of himself in the FA Cup defeat to Manchester United and also in the UEFA Champions League loss to Chelsea in midweek.
However, he was back to his best on Good Friday with a hat-trick against Liverpool in league action and is hoping regular treatment can keep him stay fit for the title run-in.
"This is a tricky injury for me," stated the Frenchman. "When my back is not responding well to treatment it upsets the nerves in my legs so I feel blocked.
"It is not the kind of injury that you can say 'yes' or 'no', sometimes it depends on how you wake up.
"With osteopathy, I can put my back right and then I don't have the nerves blocked and I can run again."
Henry added: "I have to thank the medical staff who do a great job."
Meanwhile team mate Ray Parlour is set to return to training in a bid to help Arsenal in the final few weeks of the season.
The midfielder has missed the last two months of action with a knee injury but manager Arsene Wenger is now hoping to see him return to first team action in the near future.
"Ray will join the rest of the group and could still play a big part in the title race as he can play wide midfield as well as in the centre," said the Gunners boss.
