onomic study? I would need a signal/trigger to let subject know when to squeeze and when to relax the hand dynamometer. I would also need a signal that would indicate the percentage of maximum voluntary contraction the subject needs to squeeze (+/- 10%).Because of the nature of your question (you want to measure physical/physiological signals), I decided to go with a sensible answer.
To measure EMG or any other biomedical signal, my suggestion is to use specialized biomedical instrumentation.
If you do research in any area related to the biomedical field, my recommendation is to obtain instrumentation compatible with LabVIEW, which will allow you to do your designs based on your requirements.
NI has a software called BioBench and it seems that you will be able to perform what you want with it. Although it is not clear from the webpage if you can integrate it with LabVIEW, chances are that it may be possible. Unfortunatelly, I am not familiar with BioBench. You can check more information about the BioBench in the

Now, I am familiar with BIOPAC systems. The MP system from BIOPAC can be adapted for you needs. It can be easily configured to allow you to measure exactly what you are asking. The best thing is that they also provides the drivers to interface the system with LabVIEW.
You can check more information about BIOPAC in the following page:

Answering you question more directly, the answer is yes. BIOPAC systems provide VIs designed to measure EMG and hand grip forces, and also provide VIs that will allow you to generate a signal to monitor and provide feedback to the subject.
Good luck!
