CONNECTION SETUP OF EMG AND HAND DYNAMOMETER


EMG READING OUTPUT 

  • When the subject grips the hand dynamometer, the voltage and resulting grip strength reading increases. Simultaneously, a peak occurs in the EMG graph, which is indicative of the neuromuscular signal.
  • If all of these outcomes occur at the same time, the patient is healthy. If not, it is an indication that something is wrong with the patient’s neuromuscular pathway.

  • The hand dynamometer and EMG are useful diagnostic tools to determine how well a patient’s neuromuscular pathways are functioning.
  • They are used in the medical field to monitor a patient’s progress in therapy for nerve or tendon injuries in the hand.
  • They are also used for diagnosing neuromuscular disorders such as Parkinson’s disease and Huntington’s disease.
