    Blood pressure is the force of blood pushing against the walls of arteries as the heart pumps blood around the body. Systolic pressure is the pressure when the heart contracts and pushes blood out and diastolic pressure is the pressure when the heart relaxes and fills with blood. In adults, the systolic pressure normally ranges between 80 and 120 and the...

    The Balance Error Scoring System (BESS) was used to assess balance under 3 testing stances: double leg, single leg (non-dominant leg) and tandem (dominant foot in front of the non-dominant foot in heel-to-toe fashion) on 2 surfaces (ground and foam pad). The total score was the total number of errors across the six 20-second repeated measures.
