6. Create Your Own Splint
Although this is not an active exercise, it’s still something that can be followed every night and can produce some amazing results. If you don’t want to purchase an arm splint for sleeping, simply create your own using nothing more than a bath towel and some adhesive tape.
Take a large, thick towel and wrap it up into a tube. Slide your arm through the hole and wrap the entire towel in a strong adhesive tape. The point of this exercise is to keep your arm extended throughout the night. Keeping your elbow in a flexed position will only make your symptoms worse, and 8 hours is a long time to be stuck in such a position. The towel splint may feel weird at first but you will soon get used to it and it will make a world of difference to your condition. Alternatively, you could purchase an arm splint from any major retailer.
