Thank you Tim and Richard.
@ Tim: yes, your comment is of great help, I'll get back to it later on. @ Richard: I agree that without a suspicion of a nerve injury there is no need for a S/D curve. The question is, do we always know if there is a nerve injury? My idea is that we do not and what I'm trying to make here is a clinical reasoning flow chart for the S/D curve. So let's suppose the clinical examination shows a muscle weakness and the therapist hasn't got the slightest idea where that comes from. Taking into account that it doesn't even take more than three minutes to get the accommodation quotient (AQ), my idea is that in every case of muscle weakness of unknown origin, the S/D curve is useful. With an AQ > 2.7 one can say, ok let's use NMES type currents and support the exercise therapy. With an AQ < 2.7 it's all hands on deck because we've got a nerve injury here and that requires a different approach. Does everyone agree so far?
