Minor edits to recommendation 1.3.1 to clarify meaning.
In recommendation 1.3.9 'discontinue' was changed to 'stop' for plain English purposes, and 'patient' changed to 'person'.
In recommendations 1.3.9 and 1.3.10 the words 'foot impulse' and 'devices' were deleted from recommendations because the guideline committee noted that the term 'intermittent pneumatic compression' covers both sleeves applied to the legs and garments wrapped around the foot. The options are considered equal in the recommendations. The guideline committee left it to clinicians to decide which were the most suitable.
Recommendation 1.3.11 was edited to simplify wording.
In recommendation 1.4.2, 'stroke' was changed to 'acute stroke' to make it clear the recommendation is about someone currently experiencing a stroke or having treatment for stroke, not people receiving rehabilitation treatments for stroke. 'Patients' was changed to 'people'.
Recommendations are marked as  when the evidence was last reviewed in 2010.
