Ok, my gf is a physio. A while back a paper was published looking at difference between hands on physio (eg massage/manips) vs verbal based instruction/exercise advice in the treatment of a particular kind of back pain. Study found that both groups improved, but that there was little difference between the groups who had receieved the two approaches.
Mainstream media reported this as
Physiotherapy does not help backpain
, which was completely wrong and misleading.
Reporter either missed or chose to ignore the fact that both groups HAD received physio, and both groups HAD improved.
Point is mainstream media are looking for the attention grabbing headlines, and are generally not trained/interested in reading scientific/academic studies and undersatnding their conclusions.
