toll one's shoulders

[Hermy]

Пожалуйста, помогите перевести.

Выражение встречается в следующем контексте:Mrs. Waley sat on a plain brown coach knitting her brow and a sweater. Her knees were clasped together and both her arms were tight at her sides as she concentrated on her work. Occasionally she peered over her glasses to the old clock whose ticking resonated about the room, making the passing of time seem even longer. She let out a sigh, tolled her shoulders and continued knitting, the sounds of the needles striking against one another every so often.
