Effects of rTMS combined with rPMS on stroke patients with arm paralysis after contralateral seventh cervical nerve transfer: a case-series.

OBJECTIVE: We conducted this study to evaluate the effect of rTMS combined with rPMS on stroke patients with arm paralysis after CSCNTS. METHODS: A case-series of four stroke patients with arm paralysis, ages ranging from 39 to 51 years, that underwent CSCNTS was conducted. Patients were treated with 10 HZ rTMS on the contralesional primary motor cortex combined with 20 HZ rPMS on groups of elbow and wrist muscles for 15 days. RESULTS: The muscle tone of elbow flexor muscle (EFM), elbow extensor muscle (EEM), wrist flexor muscle (WFM) and flexor digitorum (FD) reduced immediately after operation followed by increasing gradually. After rehabilitation, the muscle tone of EEM and EFM reduced by 14% and 11%, respectively. There was a 13% and 45% change ratio in WFM and FD. The numeric rating scale (mean = 5.75 ± 1.71) was significantly lower (mean = 3.25 ± 1.90, t = 8.66, p = .00). Grip and pinch strength (mean = 23.65 ± 4.91; mean = 4.9 ± 0.59) were significantly higher (mean = 34.63 ± 5.23, t = -61.07, p = .00; mean = 7.1 ± 0.73, t = -13.91, p = .00). CONCLUSIONS: The rehabilitation of stroke patients with arm paralysis after CSCNTS is a long, complicated process which includes great change of neuropathic pain, muscle tone, and muscle strength. In order to enhance the neural connection between the contralesional hemisphere and the hemiplegic limb, alleviate postoperative complications, as well as accelerate the rehabilitation process, we can consider to use rTMS combined with rPMS.

Effect of repetitive peripheral magnetic stimulation on upper limb motor function of stroke patients after contralateral seventh cervical nerve transfer / 中国康复理论与实践

ObjectiveTo explore the effect of repetitive peripheral magnetic stimulation on upper limb motor function rehabilitation of stroke patients after contralateral seventh cervical nerve transfer (CC7). MethodsFrom May, 2020, to May, 2022, 34 stroke patients with hemiplegia underwent CC7 in Jing'an District Centre Hospital of Shanghai were randomly divided into control group (n = 17) and observation group (n = 17). Both groups received conventional rehabilitation. The observation group accepted repetitive peripheral magnetic stimulation, and the control group received sham stimulation, for eight weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and Hua-Shan Grading of Upper Extremity (H-S grading) before and after treatment. ResultsTwo cases dropped down in each group. There was difference in gender between two groups (χ2 = 6.136, P < 0.05). After treatment, the scores of FMA-UE and H-S grading significantly improved in both groups (t > 4.000, P < 0.01), and the improvement was better in the observation group than in the control group (t > 2.362, P < 0.05). ConclusionRepetitive peripheral magnetic stimulation could improve the motor function of upper limb and hand of stroke patients with hemiplegia after CC7.

Huashan perioperative nursing program for stroke patients undergoing contralateral seventh cervical nerve transfer.

BACKGROUND: A previous investigation regarding contralateral seventh cervical nerve transfer (CC7) revealed a novel and effective approach to improve arm function in patients with chronic spastic paralysis. The patients who underwent both CC7 and standard rehabilitation showed greater functional improvements and spasticity reductions than patients in the control group, who underwent rehabilitation only. Additional efforts are needed to maximize the benefits in patients and establishing a supporting nursing program is a promising method for achieving this goal. METHODS: The present Huashan nursing program was established in consideration of the following elements: providing routine perioperative care, ensuring surgical safety, and improving patient cooperation. Before surgery, psychiatric nursing, health education, and risk control were emphasized. After surgery, in addition to routine nursing and positioning, special attention was needed for targeted nursing in cases of postoperative adverse events. In addition, we performed descriptive statistical analysis of the clinical data of patients participating in the Huashan nursing program, focusing on postoperative adverse events. In total, 85 patients were included in the study, 10 of whom experienced adverse events, including severe pain (5, 5.88%), neck hematoma (2, 2.35%), dyspnea (2, 2.35%), and hoarseness (1, 1.18%). The above adverse events were alleviated through the targeted nursing care guided by the Huashan program. DISCUSSION: This article introduces the Huashan nursing program, which is based on preoperative evaluations, educational sessions, postoperative monitoring, and targeted nursing, for patients undergoing CC7. This nursing program helped promote and provided the opportunity to maximize the benefits of CC7.

Neuroinflammation Mediates Faster Brachial Plexus Regeneration in Subjects with Cerebral Injury.

Our previous investigation suggested that faster seventh cervical nerve (C7) regeneration occurs in patients with cerebral injury undergoing contralateral C7 transfer. This finding needed further verification, and the mechanism remained largely unknown. Here, Tinel's test revealed faster C7 regeneration in patients with cerebral injury, which was further confirmed in mice by electrophysiological recordings and histological analysis. Furthermore, we identified an altered systemic inflammatory response that led to the transformation of macrophage polarization as a mechanism underlying the increased nerve regeneration in patients with cerebral injury. In mice, we showed that, as a contributing factor, serum amyloid protein A1 (SAA1) promoted C7 regeneration and interfered with macrophage polarization in vivo. Our results indicate that altered inflammation promotes the regenerative capacity of the C7 nerve by altering macrophage behavior. SAA1 may be a therapeutic target to improve the recovery of injured peripheral nerves.
