A description of active insufficiency in a muscle - tendon unit, and how it might influence manual muscle testing (MMT).

Realy halpful

Can that happen with single joint muscles like side delts on side raises?

Good question! Single joint muscle-tendon units are less prone to Active Insufficiency. Middle deltoid may become actively insufficient, but not until nearing the end of its range (near the end of shoulder abduction).
