Integrated volitional control electrical stimulation for the paretic hand: a case report.

[Purpose] Integrated volitional control electrical stimulation (IVES) is a type of electrical stimulation therapy that promotes agonist muscle contraction in limbs with motion paralysis. This case study describes the improvement in the paretic hand with stroke hemiplegia, eight years after the onset, with IVES for one month in the extrinsic and intrinsic muscles, including change of mode of stimulation based on the degree of improvement. [Participant and Methods] A 76 year-old male with hemiplegia for eight years. The patient was evaluated for two weeks and performed IVES in the right flexor pollicis brevis, abductor pollicis brevis, and extensor carpi ulnaris with the change of mode of IVES. [Results] The upper limb function improved in a short period of time. The hemiplegia test showed Brunnstrom stages II-III and II-IV for the right upper limb and right hand and fingers, respectively, 28 days after IVES initiation. [Conclusion] After one month of undergoing IVES, the patient showed improvement in hand and finger motor function, which was maintained even after IVES was completed. In this case, there was improvement with a short-term intervention using appropriately combined IVES modes.
