On accent in SL

[Nedelina Stoyanova Ivanova]

Hallo,

Is someone familiar with papers/researches or something regarding  acute and grave accent as known from Swedish f.ex. but related to sign languages, and in particular to path movement and hand internal movement? When only one movement (path or hand internal) is presented, than the accent is acute; when both presented, than the accent is grave?
I know, quite far-fetched ...
