OTA MMT
MMT scale, description of grade
Grade | Definition | Gravity used | Word Grade | Performance Ability |
---|---|---|---|---|
1 | Contraction can be felt or seen, but there is no motion | Gravity Eliminated | trace | completely dependent and can only perform ADL's with the aid of externally powweered devices |
2- | Part moves through incomplete ROM | Gravity Decreased | poor minus | considered below functional range, but pt can perform some ADL with mechanical assistance and ROM can be maintained independently |
2+ | Part moves through incomplete ROM (<50%) or complete ROM | Incomplete ROM against gravity; complete ROM gravity decreased against slight resistance | poor plus | considered below functional range, but pt can perform some ADL with mechanical assistance and ROM can be maintained independently |
3 | Parts move through complete ROM | Against gravity | fair | can move parts against gravity and perform light tasks that present little or no reisistance |
3- | Parts move through incomplete ROM (>50%) | Against gravity | fair minus | |
3+ | Parts move through complete ROM with slight resistance | Against gravity | fair plus | has low endurance and fatugues more easilty than one with G or N. Can perform ADL's independently but may require frequent rest periods |
4 | Parts move through complete ROM with moderate reistance | Against gravity | good | had good endurance, can perform all ordinary ADL without undue fatigue |
5 | Parts move through complete ROM with full resistance | Against gravity | Normal | had normal endurance, can perform all ordinary ADL without undue fatigue |
0 | No muscle contraction can be seen or felt | Gravity Eliminated | zero | completely dependent and can only perform ADL's with the aid of externally powweered devices |
2 | Part moves through complete ROM | Gravity Decreased | poor | considered below functional range, but pt can perform some ADL with mechanical assistance and ROM can be maintained independently |
