At http://www.englishforums.com/English/VerbObjIngForm/nqrbz/post.htm are descriptions of two different but identical-looking structures of the Verb + obj + -ing-form form:
(1) She caught Tom smoking.
(2) She needed help walking.
The first is a complex catenative ( http://books.google.co.uk/books?id=YNfzbWuMFuoC&pg=PA11&lpg=PA11&dq=complex+catenative&source=bl&ots=PXamBDZhQk&sig=x4zwAVO1mnZ-oYlpXJRdWDFQVS4&hl=en&sa=X&ei=ErTRUcDRA6mK7Aanr4CADg&ved=0CEcQ6AEwAw ).
The second really uses a two-word idiom (need help); it is, as CJ in the first link above says, not best analysed as part of a catenative structure. He gives further examples, and another pair of look-alikes are:
(3) She took Bill walking.
(4) She took care walking.
Several of these verb + noun collocations / idioms (take care, make haste, lose no time, have fun...) regularly take ing-forms (usually themselves followed by noun groups). I'd say these ing-forms were a lot nearer the verbal end of the continuum than the nounal (so I would never call them gerunds).
