  • PURPOSE: The aim of this study was to investigate the effects of exercise intensity and initial timing on functional recovery following sciatic nerve injury in rats. METHODS: Total of 80 Sprague-Dawley rats was used and randomly divided 6 groups. Under deep anesthesia, the sciatic nerve was nipped by adapted hemostatic tweezers for 30 seconds and the injured nerve was transparent under naked eyes. Acute exercise groups was applied treadmill after sciatic nerve crush injury during 5days with three type intensity. Late exercise groups was also applied treadmill during 5 days with three type intensity after 5 days break. Values of sciatic functional index were measured and analyzed in each group after exercise period. RESULTS: The sciatic functional index values between control groups 1, acute low-intensity group, acute middle-intensity group in acute phase showed statistical significant (p<.05). The sciatic functional index values between control groups 2, late low-intensity group, late middle-intensity group and late high-intensity in late phase showed statistical significant (p<.05). The comparison in acute and late phase, sciatic functional index values of each low-intensity group and each high-intensity group showed statistical significant (p<.05). CONCLUSION: Whether at acute or late phase, treadmill exercise as a therapy obtained beneficial effects of functional recovery and exercise training at low speed is more beneficial effects on the recovery of motor function in acute phase.

  • The purpose of this study was to assess the feasibility of task-oriented arm training for chronic hemiparetic stroke patients. The experimental design in this study was the pre-test and post-test with control group for 4-week intervention. Thirty patients with chronic hemiparetic stroke were recruited from 2 rehabilitation units. The subjects were divided randomly into experimental and control groups. The experimental group conducted task-oriented approach, involving 3 subparts of upper extremity activities, and the control group involved in the general upper extremity exercises. Functional movements of the upper extremities were assessed using clinical measures, including the Fugl-Meyer Assessment-Upper Extremity Section, Box and Block Test, and Action Research Arm Test. The score of Fugl-Meyer Assessment showed greater increases in the experimental group than in the control group after training. The improvement in Box and Block Test between pre-test and post-test measurements was significantly greater after task-oriented arm training compared to general upper extremity exercises. Action Research Arm Test scores also improved after task-oriented arm training compared to exercises in the control group. The task-oriented arm training improves the gross and fine motor activities and encouraging the use of the paretic arm through activity dependent intervention expedites the recovery of functional activities in the upper extremities for chronic hemiparetic stroke.

  • Purpose: The purpose of this study was to determine the effect of direct functional magnetic stimulation (FMS) of affected spinal cord on motor recovery following spinal cord injury in rats. Methods: After a contusion injury at the spinal level T9 using an NYU Impactor, functional magnetic stimulation was delivered by a magnetic stimulator through a round prototype coil (7 cm in diameter). Stimulation parameters were set as follows: repetition rate = 50 Hz (stimulus intensity 100% = 0.18 T), stimulation time = 20 min. Functional magnetic stimulation was administered twice a day, 5 days per week for 8 weeks starting 4 days after spinal cord injury. Functional magnetic stimulationwas delivered directly to the affected spinal cord. Outcomes of locomotor performance were assessed by the Basso Beattie Bresnahan (BBB) locomotor rating scale and by an inclined plane test weekly for 8 weeks. Results: In the BBB test, hindlimb motor function in the Functional magnetic stimulation group improved significantly more compared to the control group at 3, 4, 6, 7, and 8 weeks (p<0.05). In the inclined plane test, the angle of the plane in the functional magnetic stimulation group increased significantly more compared to the control group at 4, 5, 7, and 8 weeks (p<0.05). Conclusion: Our results demonstrate that direct Functional magnetic stimulation of the lesional site may have beneficial effects on motor improvement after spinal cord injury.

  • Reconstruction of the upper lateral lip subunit is challenging, and use of several classical local flaps have been previously reported. However, these methods have drawbacks such as visible scarring, anatomic distortion, and functional disability. To obtain satisfactory results, preservation of perioral function is important. We report a case of functional upper lip reconstruction after tumor resection using a reverse facial-submental artery island flap with a reinnervated anterior belly of the digastric muscle (ABDM) without sacrificing the perioral structure. A 73-year-old man presented with basal cell carcinoma on the left upper lip which was widely excised, including the orbicularis oris muscle. The remaining 4 cm × 3.5 cm defect was reconstructed using a reverse facial-submental artery island flap with ipsilateral ABDM. The motor nerve of the ABDM was sutured with the stump of the buccal branch of the ipsilateral facial nerve. The postoperative course was uneventful, and good functional and esthetic recovery were observed at 12-month follow-up. This procedure may be an alternative option for reconstruction of lateral upper lip defects.

  • Objective: Valproic acid (VPA), as known as histone deacetylase inhibitor, has neuroprotective effects. This study investigated the histological changes and functional recovery from spinal cord injury (SCI) associated with VPA treatment in a rat model. Methods: Locomotor function was assessed according to the Basso-Beatlie-Bresnahan scale for 2 weeks in rats after receiving twice daily intraperitoneal injections of 200 mg/kg VPA or the equivalent volume of normal saline for 7 days following SCI. The injured spinal cord was then examined histologically, including quantification of cavitation. Results: Basso-Beatlie-Bresnahan scale scores in rats receiving VPA were significantly higher than in the saline group (p<0.05). The cavity volume in the VPA group was Significantly reduced compared with the control (saline-injected) group (p<0.05). The level of histone acetylation recovered in the VPA group, while it was significantly decreased in the control rats (p<0.05). The macrophage level was significantly decreased in the VPA group (p<0.05). Conclusion: VPA influences the restoration of hyperacetylation and reduction of the inflammatory reaction resulting from SCI, and is effective for histology and motor function recovery.

  • Traumatic brachial plexus injuries can be devastating, causing partial to total denervation of the muscles of the upper extremities. Surgical reconstruction can restore motor and/or sensory function following nerve injuries. Direct nerve-to-nerve transfers can provide a closer nerve source to the target muscle, thereby enhancing the quality and rate of recovery. Restoration of elbow flexion is the primary goal for patients with brachial plexus injuries. A 4-year-old right-hand-dominant male sustained a fracture of the left scapula in a car accident. He was treated conservatively. After the accident, he presented with motor weakness of the left upper extremity. Shoulder abduction was grade 3 and elbow flexor was grade 0. Hand function was intact. Nerve conduction studies and an electromyogram were performed, which revealed left lateral and posterior cord brachial plexopathy with axonotmesis. He was admitted to Rehabilitation Medicine and treated. However, marked neurological dysfunction in the left upper extremity was still observed. Six months after trauma, under general anesthesia with the patient in the supine position, the brachial plexus was explored through infraclavicular and supraclavicular incisions. Each terminal branch was confirmed by electrophysiology. Avulsion of the C5 roots and absence of usable stump proximally were confirmed intraoperatively. Under a microscope, neurotization from the musculocutaneous nerve to two medial pectoral nerves was performed with nylon 8-0. Physical treatment and electrostimulation started 2 weeks postoperatively. At a 3-month postoperative visit, evidence of reinnervation of the elbow flexors was observed. At his last follow-up, 2 years following trauma, the patient had recovered Medical Research Council (MRC) grade 4+ elbow flexors. We propose that neurotization from medial pectoral nerves to musculocutaneous nerve can be used successfully to restore elbow flexion in patients with brachial plexus injuries.
