    Abstract Abstract: Ultrasonography (US) has recently been used more frequently during interventions involving the lumbar spine. However, physicians who are more familiar with musculoskeletal US targeting muscles, tendons, and nerves may find it challenging to perform US-guided lumbar spine interventions using only bony landmarks. This study described the use of color Doppler US for the visualization of the lumbar spinal blood supply to identify vascular landmarks in addition to bony landmarks and thus more easily and accurately perform lumbar spine interventions.

    Abstract Purpose: Peripheral nerve damage lacks an appropriate diagnosis consistent with the patient's symptoms, despite expensive magnetic resonance imaging or electrodiagnostic assessments, which cause discomfort. Ultrasonography is valuable for diagnosing and treating nerve lesions; however, it is unsuitable for detecting small lesions. Poly(vanillin-oxalate) (PVO) nanoparticles are prepared from vanillin, a phytochemical with antioxidant and anti-inflammatory properties. Previously, PVO nanoparticles were cleaved by H
    Methods: To induce sciatic neuritis, rats were administered a perineural injection of carrageenan using a nerve stimulator under ultrasonographic guidance, and PVO nanoparticles were injected perineurally to evaluate ultrasonographic contrast and therapeutic effects. Reverse transcription-quantitative PCR was performed to detect mRNA levels of pro-inflammatory cytokines, ie, tumor necrosis factor-α, interleukin-6, and cyclooxygenase-2.
    Results: In the rat model of sciatic neuritis, PVO nanoparticles generated CO
    Conclusion: The results of the current study suggest that PVO nanoparticles could be developed as ultrasonographic contrast agents and therapeutic agents for nerve lesions.

    Abstract The purpose of this study is to confirm the effect of small, portable low-level laser therapy (light sources in square configuration: 830 nm GaAs diode 3.2 mW at the center, 4 × 650 nm InGaAIP diodes over the corners) treatment in reducing and enhancing hand function in patients with wrist pain. This study was a prospective, randomized, sham-controlled, and home-based self-therapy trial. A total of thirty subjects with wrist pain were enrolled. All participants received low-level laser therapy on painful area at the wrist. The experimental group (n = 15) received laser stimulation, while the control group (n = 15) received sham stimulation using identical equipment that generated only a red light without the laser output. Both groups self-treated for 30 min a day, 5 days per week for 3 weeks, total of 15 sessions. The primary outcome was assessed using a visual analogue scale (VAS) for wrist pain from 0 (painless) to 10 (extreme pain). The secondary outcomes were measured with patient-rated wrist evaluation (PRWE), grip strength, lateral, palmar, and tip pinch strength. Measures were taken before and after treatment. A total of thirty participants provided outcome data. After the intervention, both groups showed a significant decrease in VAS score, from 4.93 to 3.67 in experimental group, from 5.53 to 4.00 in control group (the experiment group: p = 0.020, the control group: p = 0.003). The experimental group showed a significant improvement in function scale score (p = 0.012), the control group did not. Lateral and pinch strength was significantly improved in the experimental group (p = 0.017) and in the control group (p = 0.034) respectively. There were no side effects in the patients. Medical laser irradiation is a portable and easy-to-use laser irradiator without side effects. Clinical Trial Registration number: KCT0006604.

    Abstract Mild cognitive impairment (MCI) increases with aging society. Serious games may be effective in improving cognitive function in patients with MCI; however, research on their effects remains insufficient. This study aimed to confirm the efficacy and safety of cognitive rehabilitation training using a serious game (Brain Talk™) for the elderly with MCI. Twenty-four elderly individuals with MCI were randomized into study and control groups. The study group received 12 training sessions (30 min/session, 3 times/week), whereas the control group did not receive training. Blinded evaluations were conducted before and after the training and four weeks after the training. The primary outcome measures were the Korean Mini-Mental State Examination (K-MMSE) and K-MoCA (Korean Montreal Cognitive Assessment). Secondary outcome measures were the Semantic Verbal Fluency Task (SVFT), Trail-Making Test-B, and 2-back test. In the study group, the K-MMSE, K-MoCA, and SVFT scores after finishing the training and 4 weeks after training showed a significant increase; however, there was no significant change in the control group. No significant differences were observed between the two groups. Cognitive function significantly improved in the study group after training. Home-based serious games are considered helpful in improving cognitive function.

    Abstract To the best of our knowledge, the upper age limit at which post-neonatal cerebral palsy (CP) can manifest remains uncertain. This uncertainty is attributed to the lack of objective parameters for assessing the developing brain. In a previous study, we reported that an ipsilateral corticospinal projection associated with brain injury, as manifested in the paretic hand of a CP patient, had never been observed in individuals aged > 2 years. In this case report, we present an instance of ipsilateral motor evoked potential (iMEP) in a girl whose traumatic brain injury occurred at the age of 4 years. This case is the oldest in which brain injury occurred and iMEP was maintained. In conclusion, iMEP can be a valuable indicator of motor system plasticity in the developing brain.

    Abstract Background: Ischemia reperfusion (IR) injury may result in rhabdomyolysis and compartment syndrome when blood supply returns after thrombectomy for patients with acute limb ischemia.
    Objective: We highlight the value of early diagnosis and treatment in post-thrombectomy patients with IR injuries in their lower legs.
    Case description: Two patients received thrombectomy due to left superficial femoral artery occlusion. Both patients complained of left calf pain during ambulation at the 1- and 3-day follow up post-thrombectomy, as well as a heating sensation, swelling, weakness, and sensory changes in the affected leg. For early diagnosis musculoskeletal ultrasounds were performed and in both cases revealed swelling and change of echogenicity in the left calf. To further diagnosis, magnetic resonance imaging of the left leg revealed limb IR-induced muscular injury and rhabdomyolysis, respectively. In both cases, an electrodiagnostic study revealed peripheral nerve injury in the left leg. Medications were provided for neuropathic pain control and early rehabilitation was performed to improve function. In both cases, patients reported during their follow-up that their pain and muscle weakness had improved.
    Conclusion: When post-thrombectomy calf pain occurs early evaluation and treatment should be performed to identify any potential IR injury.

    Abstract Dysphagia induced by anterior cervical osteophytes (ACOs) is frequently reported in older individuals. Surgical resection of ACOs is considered when conservative treatment fails, but its effectiveness is controversial owing to side effects after surgery. We present the case of a 78-year-old man who complained of progressive dysphagia that started 10 months previously. A videofluoroscopic swallow study (VFSS) showed prominent ACOs along C2-C6, which translocated the upper hypopharynx anteriorly, impinging the lumen and impairing epiglottic folding and laryngeal closure. Aspiration of a soft diet was observed. Despite conservative therapy, the symptoms persisted, and ACO resection surgery was performed. Unexpectedly, the patient's dysphagia worsened immediately post-surgery. A VFSS on postoperative day (POD) 2 showed improvement in epiglottic folding. However, prevertebral soft tissue swelling and dysfunction of opening of the upper esophageal sphincter newly arose. Laryngeal aspiration was observed during 5 cc and a large amount of liquid swallowing trials. The patient was provided a modified diet and rehabilitative dysphagia therapy. A VFSS on PODs 6 and 14 showed a gradual improvement in the prevertebral soft tissue swelling. This report suggests that a serial VFSS is effective for evaluating the different mechanisms of dysphagia and for devising an appropriate treatment plan.

    Abstract Objective: To compare clinical findings and urodynamic parameters according to trabeculation grade and analyze their correlations with trabeculation severity in neurogenic bladder caused by suprasacral spinal cord injury (SCI).
    Methods: A retrospective chart review was performed of neurogenic bladder caused by SCI. Bladder trabeculation grade was compared with SCI-related clinical parameters and bladder-related urodynamic parameters.
    Results: In SCI patients, factors such as disease duration, bladder capacity, detrusor pressure, peak detrusor pressure values, and compliance were significantly different between different grades of bladder trabeculation, while neurological level of injury, completeness, and detrusor sphincter dyssynergia had no clear relationship with bladder trabeculation grade. In the correlation analysis, vesicoureteral reflux was moderately correlated with trabeculation grade (correlation coefficient 0.433), while the correlation coefficients of disease duration, involuntary detrusor contraction, and bladder filling volume were between 0.3 and 0.4.
    Conclusion: Bladder trabeculation with suprasacral-type neurogenic bladder was graded. Although disease duration was positively correlated with bladder trabeculation grade, differences in the neurological level of injury or American Spinal Injury Association Impairment Scale score were not observed. Bladder volume, peak detrusor pressure, compliance, reflex volume, and vesicoureteral reflux also showed significant differences according to trabeculation grade. Vesicoureteral reflux was moderately correlated with trabeculation grade.

    Abstract Context: Whole-body vibration (WBV) training improves muscle strength and balance. Few studies have focused on the effects of WBV frequencies below 30 Hz. We aimed to investigate the effect of low-frequency WBV training on muscle activity, fatigue recovery, and oxygen consumption (VO2).
    Design: Prospective single-group, repeated-measures study.
    Methods: In this controlled laboratory setting study, 20 healthy adults (age 23.26 [1.66] y) performed half squats at 0, 4, 6, 8, 12, 16, 20, 24, and 30-Hz WBV. Muscle activity was evaluated using the root mean square and peak electromyography amplitude of 6 muscles (iliocostalis, rectus abdominis, rectus femoris, biceps femoris, tibialis anterior, and gastrocnemius) obtained via surface electromyography. VO2 was measured during the squats using a gas analyzer, and fatigue recovery was evaluated using measurements of lactate after the squats and after a recovery period. Statistical significance was set at P < .05, and analysis of variance was conducted to determine differences in muscle activity, fatigue, recovery, and VO2, with post hoc analyses as appropriate.
    Results: Of the 6 muscles measured, the muscle activity of the gastrocnemius alone significantly increased from 0 Hz at 4, 8, 12, 16, 24, and 30 Hz based on the root mean square values and at 4, 8, 12, and 30 Hz based on the peak electromyography amplitude values. There were no significant differences in the other muscles. There were no significant differences in VO2 or in lactate levels.
    Conclusions: Low-frequency WBV during squat exercises significantly increased the activity of the gastrocnemius medialis only at specific frequencies in healthy young adults. Low-frequency WBV is safe and has the potential to increase muscle activity.
