3. What are Sprains & Strains?
Sprains and strains are two types of MSDs, or
musculoskeletal disorders
MSD’s are injuries or disorders of the:
muscles, nerves, tendons, joints, cartilage, and
supporting structures of the upper and lower limbs, neck and lower back that are caused, precipitated, or exacerbated by sudden exertion or prolonged exposure to physical factors (e.g. force, repetition, vibration or awkward posture)
- CDC/NIOSH 3

4. Causes of Sprains & Strains?
They are caused by excessive
reaching, bending, lifting,
gripping, squatting, or twisting of
hands, shoulders or body
Caused by any work performed
with high force, with many
repetitions, or in an awkward
position 4

5. Causes of Sprains & Strains?
A sprain is a stretch or tear of a
ligament (band of fibrous
tissue that connects two or
more bones at a joint);
stretched too far from normal
position
One or more ligaments
may be injured at the same
time
Most common:
- sprained ankle 5

6. A strain is an injury to a muscle or tendon (thick,
What’s the Difference?
A strain is an injury to a muscle or tendon (thick,
tough fibrous cord of tissue that connects a muscle
to a bone)
Can be as simple as overstretching a muscle or
tendon, or it can be a partial or
complete tear
Most common: strained back 6

7. Types of Sprains & Strains
Back injuries, including pulled back muscles and
ruptured discs
Squashed nerves causing severe pain, such as
carpal tunnel in wrist or sciatic leg pain from back
Ligament sprains in the upper body
Shoulder muscle sprains and dislocations
Abdominal hernias
Tendon injuries to the hands, forearms and elbows
(tennis elbow)
Ankle sprains and strains 7

8. Carrying, holding, or restraining items, people or animals
How Do They Occur?
Carrying, holding, or restraining items, people or
animals
Lifting, pushing, holding or pulling loads
Working in a fixed position with the back bent,
sitting or standing continuously, or driving vehicles
for long periods
Repetitive tasks such as reaching to lift or lower
objects, or to grip tools continuously
Working in awkward positions involving bending or
twisting your body to reach items
Vibrations through the body like driving a truck or
using a powered hand tool

12. What are the Signs & Signals?
For a sprain: Pain, swelling,
bruising, not being able to move
the joint
For a strain: Pain, muscle
spasms, muscle weakness,
swelling, cramping, trouble
moving the muscle 12

13. Treatments for Sprains & Strains
FIRST STAGE – to reduce swelling and pain
RICE therapy (Rest, Ice, Compress, Elevate)
for the first 24 to 48 hours
Rest the injured area (reduce regular exercise or activities as needed)
Ice the injured area, 20 minutes at a time, four to eight times a day (cold pack, ice bag, or plastic bag filled with crushed ice and wrapped in a towel can be used) 13

14. Treatments for Sprains & Strains
Compress the injured area, using bandages, casts,
boots, elastic wraps or splints to help reduce swelling
4. Elevate the injured area, above the level of the heart, to help decrease swelling while you are lying or sitting down 14

15. Treatments for Sprains & Strains
Health care provider may recommend an anti-inflammatory
drug such as aspirin (Bayer), ibuprofen (Advil, Motrin), or
acetaminophen (Tylenol) to help decrease pain and
inflammation
If moderate sprain, may require use of mobility aids, such as
a cane, crutches, a walker or wheelchair
If severe sprain, may need surgery to repair torn ligaments,
muscle or tendon 15

16. Treatments for Sprains & Strains
SECOND STAGE – Rehabilitation
Physical therapy/exercise program: designed to help reduce swelling, prevent stiffness and restore normal, pain-free range of motion (during first week after injury) 16

17. Treatments for Sprains & Strains
2. Increase strength and flexibility (about second week after injury); usually more demanding exercises to improve function 17

18. Treatments for Sprains & Strains
Advanced stretching? 18

19. Treatments for Sprains & Strains
3. Return to full daily activities, including
sports if appropriate; must work closely
with physical therapist to avoid re-injury 19

20. Time needed for full recovery: Mild sprain/strain: three to six weeks
How Much Time to Heal?
Time needed for full recovery:
Mild sprain/strain: three to six weeks
Moderate sprain/strain: two to three months
Severe sprain/strain: eight to months 20

21. Although we cannot prevent all sprains and
How Can We Prevent This?
Although we cannot prevent all sprains and
strains from occurring, there are some tips on how
to avoid them:
- Stretch before you workout or
move heavy items
- Wear proper footwear for the activity you are doing 21

22. How Can We Prevent This? Warm up adequately before activities
Be aware and avoid slippery/ uneven surfaces. If unable to, proceed with CAUTION. 22

23. Sprains and strains are classified as muscular- skeletal disorders
Summary
Sprains and strains are classified as muscular-
skeletal disorders
Many causes including carrying, pushing,
lifting, pulling, doing repetitive tasks, or
working in awkward positions
Treat by using RICE (Rest, Ice, Compression,
Elevation)
Prevent by stretching, wearing proper
footwear, using caution while walking 23
