We compared the response of articular cartilage subjected to muscle stretching at different frequencies after joint immobilization. Wistar rats with immobilized left hind limbs were classified into the following groups: immobilization, immobilization followed by muscle stretching applied daily (group IS7) or three times a week (IS3), muscle stretching applied daily (S7) or three times a week (S3), and a control group (C) that underwent no intervention. We then evaluated the cartilage for cellularity, loss of proteoglycans, collagen density, and immunostaining of fibronectin and chondroitin 4-sulfate.

- The study evaluated how muscle stretching after immobilization affects ankle cartilage in rats.
- Twenty-nine Wistar rats were divided into five groups, with one group focused on stretching after a four-week immobilization period.
- Results showed that the group that performed stretching post-immobilization had improved cartilage health, particularly in proteoglycan levels, indicating that the cartilage can recover from damage due to increased cell density.
To evaluate the remodeling of collagen fibers in the articular cartilage of rat ankles, with and without immobilization, after application of muscle stretching protocol. Twenty three Wistar rats were divided into four groups: immobilized (I), n=6; immobilized and stretched (IS), n=6; stretched (S), n=6 and control (C), n=5. The animals in groups I and IS were submitted to immobilization.
