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) PPT-053-01 13

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 PPT-053-01 14

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) PPT-053-01 16

Treatments for Sprains & Strains 2. Increase strength and flexibility (about second week after injury); usually more demanding exercises to improve function PPT-053-001 17

Treatments for Sprains & Strains Advanced stretching? PPT-053-01 18

Treatments for Sprains & Strains 3. Return to full daily activities, including sports if appropriate; must work closely with physical therapist to avoid re-injury PPT-053-01 19

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 12 months PPT-053-01 20

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 with heavy items - Use proper footwear for the activity you are doing PPT-053-01 21

Do not run on icy/uneven surfaces How Can We Prevent This? Warm up adequately before activities Do not run on icy/uneven surfaces PPT-053-01 22

Sprains and strains are classified as musculo- skeletal disorders Summary Sprains and strains are classified as musculo- 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 PPT-053-01 23
