Sprains and strains are classified into three main forms, depending on the severity are as follows:
1. Grade I (Mild): This type involves minute stretching of tissues.
- Minor swelling and pain, which is hardly observable
- Mild loss of movement and upto 25% strength reduction.
- Stability remains unaffected
2.Grade II (Moderate): In this type of strain muscle stretching is accompanied by minor tissue breakdown.
- Moderate swelling looks like a "baseball" size. It is also seen bruising.
- Moderate loss of movement and strength reduction i.e. 25-75%.
- A decrease in stability at lessening the extent
3.Grade III (Severe): Thus third type involves the n this type a complete breakdown of tissues
- Severe swelling and bruising, which is observable
- Almost complete loss of movement and strength reduction i.e. 75 – 100%
- Loss of stability to a greater extent
Types of Sprains and Strains classified as per injury location
Sprains and strains are both injuries but occurring at different locations.
Generally, sprain makes the ligaments overstretched, torn, or twisted. The ligaments are surrounded by the joints and connect one bone to the other bones or cartilage. The main sprain areas of the body are:
In contrast to a sprain, strain occurs when muscles or tendons become overstretched, torn, or twisted. A tendon links the muscles to bones. Commonly strained areas of the body are:
