Execution:
- Place 3 strips of tape on the ground in a Y shape. The angles between the anterior stripe and both posterior stripes are 135° with 90° between both posterior stripes
- Before starting the test, 4-6 practice trials in each direction are allowed after which your patient can rest for 5 minutes
- For the anterior reach, the stance foot is placed with the toes on the zero mark position of the anterior reach direction line. For the posteromedial and posterolateral reaches the heel is placed at the zero mark position of the anterior reach direction line
- To start, have your patient stand barefoot on one limb with his hands on his hips. Then ask him to reach as far as possible on each tape stripe with his foot of the other limb touching the ground only lightly with the toes
- For the anterior direction 3 consecutive trials are performed with one limb, followed by the other limb. This procedure is repeated for the posteromedial and posterolateral directions
- The examiner marks the most distal point on the tape with a pen for each trial and each round
N.B. A trial is not considered complete if the participant touches the tape heavily, comes to rest at the midpoint, has to make contact with the ground to maintain balance or shifts the foot of the stance limb during the trial
Outcome: The average reach of the 3 trials in each direction are calculated (p.e. direction 1 = (Reach 1 + Reach 2 + Reach 3) / 3). In total 6 values (3 for the right leg and 3 for the left leg) are calculated.
Then the average distance in each direction is calculated and divided through the patient’s leg length multiplied by 100. (Average distance in each direction / leg length * 100) for a percentage score.
