At the European Wheelchair Fencing Championship held in Glasgow in 1987, the German Rita Strohm first proposed a new classification system proposal, later made some changes will be formed in the final version of the Paralympic Games in Seoul. This new functional grading system takes full account of the various factors that allow athletes of different disability (amputation, poliomyelitis, cerebral palsy and paraplegia) to participate in the competition.

Functional tests (performed in a wheelchair) include the assessment of the extensibility, the measurement of the chest roll in different directions (in the case of a sword or without a sword). The action to be tested is to repeat the technical action in the game, such as a sudden body roll when holding the sword, with the elbow extension, the chest's fast return (or tilt in the opposite direction). To assess the score in the test, the purpose of these tests is to avoid the athletes in the game was opponents hurt. The score in the test is as follows:

0 minutes - do not have the physical function, can not implement technical action;

1 point - very poor action execution ability, the ability to carry out the smallest range of activities;

2 points - relatively weak action execution ability, able to carry out medium range of activities;

3 points - normal action execution ability.

Test 1: upper body stretch ability

Including the assessment of the ability of the back muscles to stretch: the test person sitting in a wheelchair, so that it is in a forward state, and then let it through the contraction of the back muscles and keep the balance of the upper limb back to the integrity of the sitting position.

Test 2: Side balance capability

The opponent's upper limbs are fixed and the lateral balance control capability is measured: the tester bent his torso to the left and right to the maximum tilt until it was out of balance. In this way, you can assess the function of the trunk side of the muscles and abdominal side of the function of the muscles.

Test 3: Abdominal stretch ability

Similar to Test 1, the ability to stretch the torso is evaluated, but the focus is primarily on abdominal muscles. In the test, the subject is asked to put his hands in the neck, so that you can exclude the inertia of upper limb movement and the ability of the trunk back muscles.

Test 4: the balance of the sword side of the ability

Similar to Test 2, but it is more difficult to measure because the subject must be armed with a sword and the weight of the sword will significantly reduce its ability to maintain balance during the body roll.

It is very important that is done
