Here are some simple exercises you can do at home, to help with muscle strengthening in order to help prevent falls.
1. Single Leg Balance
Stand near a chair or stable object. Hold with both hands. When steady take one hand off, if steady lift one leg, hold for 10 seconds. If still steady take other hand off and hold. Build up holding the hands free for 45 seconds.
Repeat with other leg.
2. Tandem Balance
Stand near a stable object and hold for stability. Put one foot directly in front of the other. Lift one hand and try to hold that position for 10 seconds. If stable, lift the other hand and hold that position for 10 seconds gradually build up to holding 30 seconds.
Repeat with other foot in front
If the having one foot directly in front of the other is too difficult. Take a big step forward. Try to not hold onto anything and hold for 1 minute. When you improve with this exercise, try with one foot directly in front of the other.
