“…Together with previous findings [1]–[9], [33], our results again suggest that the combination of voluntary contraction and sensory electrical stimulation might be an adjuvant therapy for motor rehabilitation, because sensory electrical stimulation does not disturb active movement significantly. For example, it is possible to use this method for locomotor training such as treadmill walking with partial body weight support [34], robot-assisted locomotor training [35], or pedaling exercise [36].…”

“…In addition, the present study also indicated that corticospinal excitability is modulated by the level of voluntary contraction. This means that active movement by daily activities and training [9], [33] may selectively increase corticospinal excitability. These aspects, together with the proven efficacy of the combination therapy on functional recovery and brain reorganization in patients with central nervous system injuries [4]–[9], suggest that the combination of voluntary contraction and ES can be effectively used in rehabilitation programs for these patients.…”

While previous studies have assessed changes in corticospinal excitability following voluntary contraction coupled with electrical stimulation (ES), we sought to examine, for the first time in the field, real-time changes in corticospinal excitability. We monitored motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation and recorded the MEPs using a mechanomyogram, which is less susceptible to electrical artifacts. We assessed the MEPs at each level of muscle contraction of wrist flexion (0%, 5%, or 20% of maximum voluntary contraction) during voluntary wrist flexion (flexor carpi radialis (FCR) voluntary contraction), either with or without simultaneous low-frequency (10 Hz) ES of the median nerve that innervates the FCR. The stimulus intensity corresponded to 1.2× perception threshold. In the FCR, voluntary contraction with median nerve stimulation significantly increased corticospinal excitability compared with FCR voluntary contraction without median nerve stimulation (p<0.01). In addition, corticospinal excitability was significantly modulated by the level of FCR voluntary contraction. In contrast, in the extensor carpi radialis (ECR), FCR voluntary contraction with median nerve stimulation significantly decreased corticospinal excitability compared with FCR voluntary contraction without median nerve stimulation (p<0.05). Thus, median nerve stimulation during FCR voluntary contraction induces reciprocal changes in cortical excitability in agonist and antagonist muscles. Finally we also showed that even mental imagery of FCR voluntary contraction with median nerve stimulation induced the same reciprocal changes in cortical excitability in agonist and antagonist muscles. Our results support the use of voluntary contraction coupled with ES in neurorehabilitation therapy for patients.

“…Similarly, Yamaguchi et al5 ) reported significant improvement in wrist dorsiflexion myogenic potential in 10 patients (mean of 4.1 years elapsed since onset (range, 1.0 to 19.6 months) and mean age of 74.6 years (range, 67 to 86)) by implementing the power assist mode of IVES for 6 hours per day for 5 days. In the present case, various IVES modes were used, and an improvement was observed with one month of intervention, 20 minutes per day, 3 days per week, suggesting that upper limb function improvement can be expected even with short-term intervention by appropriately combining modes.…”

[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.

“…For instance, hand function was improved by NMES in patients with mild stroke (49-64 in UFMA) (dos Santos-Fontes, 2013). The function of the upper extremity also showed a statistically significant improvement after electrical stimulation over wrist extensor muscles in mild stroke patients (50.8 ± 5.8 in UFMA) (Yamaguchi, 2011). Similarly, rTMS over the unaffected M1 also improved mild motor dysfunction.…”

BACKGROUND: Motor dysfunction after stroke might be improved by neuromuscular electrical stimulation (NMES) combined with 1 Hz repetitive transcranial magnetic stimulation (rTMS) in patients with moderate and severe motor dysfunction. OBJECTIVE: This preliminary study tested the effect of this treatment combination. METHODS: Fifteen patients (60.5 ± 10.3 years old) participated in the study. All patients had been affected by cerebral artery infarction or hemorrhage and had moderate or severe motor dysfunction in their affected hand. The patients received NMES at paretic wrist extensor muscles combined with rTMS over the unaffected M1 hemisphere twice a day, six days/week over two weeks. All participants underwent the following battery of tests to evaluate the motor function of the affected hand: Upper limb Fugl-Meyer Assessment (UFMA), Wolf Motor Function Test (WMFT), and Box and Block Test (BBT). RESULTS: UFMA, WMFT, and BBT scores improved significantly after the study. CONCLUSIONS: These results suggest that NMES combined with rTMS could be useful for recovery of moderate and severe motor function after stroke.
