Another major win for physiotherapy -- curing patellofemoral pain.

Thanks for the positive feedback about BJSM’s recent articles – particularly the January (http://bjsm.bmj.com/content/ vol43/issue1) and February (http://bjsm. bmj.com/content/vol43/issue2) issues edited by Professor Steven Blair. Many emails supported the claims that physical activity is the most powerful single medical intervention. The downside is that Neville Owen has made me feel guilty if I sit for a mere 12 hours. The result? Ageing BJSM editor shuffling around the streets of Vancouver at 10 pm getting his ‘‘fix’’ in 3uC temperatures. The voices of Steven Blair and Art Kramer in my head penetrating the usual cacophony, ‘‘30–60 minutes a day keeps dementia at bay’’. ‘‘Too late!’’ you say?
