Question

Pete, who has been moving furniture all day, arrives at the clinic complaining of painful spasms in his back. he reports having picked up a heavy table by stooping over. what muscle group has pete probably strained, and why are these muscles at risk when one lifts objects improperly?

Answer 1

Answer : Trapezius muscle

Explanation : Pete was busy moving the furniture all day, he got painful spasms in his back because of trapezius muscle got strained along with the flexors and extensors muscle. Trapezius muscle is one of the major muscles in the back which is responsible for moving, rotating, and stabilizing the scapula and extending the head at the neck. The extensor muscle which allow for standing and lifting heavy objects also was strained along with the flexor muscle which enables flexing, bending forward, lifting, and arching the lower back.

The position of trapezius muscle at the back of shoulder imparts a strain while lifting heavy objects and is at risk when the objects are lifted improperly.

Answer 2

Pete has probably strained his lower back muscles due to improper lifting techniques. These muscles are at risk when one lifts objects improperly because of added stress on the lower back muscles. If the leg muscles are not utilized correctly during lifting, then the lower back muscles have to overcompensate for the lifting load.
