The squat is one of the most frequently prescribed exercises in the rehabilitative setting. Performance of the squat can be modified by changing parameters such as stance width, foot rotation, trunk position, tibia position, and depth. An understanding of how the various squatting techniques can influence joint loading and muscular demands is important for the proper prescription of this exercise for various clinical conditions. The purpose of this clinical commentary is to discuss how the biomechanical demands of the squat can be influenced by various modifiable parameters. General recommendations for specific clinical conditions are presented.

Selinexor is a novel XPO1 inhibitor approved for patients with relapsed refractory multiple myeloma. When used as twice weekly dosing, selinexor is associated with significant toxicities, prohibiting its use in clinical practice. Newer combinations with other chemotherapeutic agents have evaluated less frequent and lower doses of Selinexor with aggressive supportive care. These novel combinations appear to have tolerable safety profiles while preserving drug efficacy, making Selinexor a reasonable option for patients with heavily pretreated relapsed refractory multiple myeloma.
