Effect of computerized cognitive rehabilitation in comparison between young and old age after traumatic brain injury.

INTRODUCTION: Cognitive dysfunction reduces patients' quality of life and social participation with traumatic brain injury (TBI). Computerized cognitive rehabilitation is increasingly being used for cognitive therapy in TBI patients. The purpose of this study was to investigate the influence of age on the effect of computerized cognitive rehabilitation in cognitive dysfunction after TBI. MATERIAL AND METHODS: A total of 34 patients with cognitive dysfunction after TBI were enrolled. Participants performed 30 sessions of computerized cognitive rehabilitation (Comcog) for 6 weeks. A cognitive evaluation was performed before and after treatment with Mini-Mental State Examination (MMSE) and Computerized Neurophyschologic Test (CNT). RESULTS: There were no cognitive tests that differed between the young group and the old group at baseline. However, after computerized cognitive rehabilitation, the young group showed significant improvement compared to the old group in verbal memory, visual memory, attention, and visuo-motor coordination tests. The young group showed improvement in MMSE, verbal and visual memory, and visuo-motor coordination tests after computerized cognitive rehabilitation. In contrast, the old group showed significant improvement only in MMSE and visual learning test, one of the visual memory tests. CONCLUSION: Our findings demonstrate that age may be an important factor related to the effect of computer cognitive rehabilitation on cognitive dysfunction after TBI. Methodologically more ordered studies with larger sample sizes are needed in the future.

Correlation Between Maximal Tongue Pressure and Swallowing Function in Spinal and Bulbar Muscular Atrophy.

Background: Spinal and bulbar muscular atrophy (SBMA) is an X-lined motor neuron disease characterized by progressive muscle weakness, bulbar palsy, and dysphagia. Dysphagia is associated with tongue weakness, which is a common manifestation of SBMA. This study aimed to investigate the correlations between tongue pressure and dysphagia in patients with SBMA. Materials and Methods: Thirty-nine genetically confirmed SBMA patients underwent a videofluoroscopic swallowing study (VFSS) and tongue pressure assessment. Then, we analyzed the maximal tongue pressure (MTP), oral transit time, penetration-aspiration scale (PAS), videofluoroscopic dysphagia scale (VDS), amyotrophic lateral sclerosis functional rating scale-revised (ALSFRS-R), and 6-min walk test (6MWT). Pearson and Spearman correlation coefficients were calculated to analyze the association of the MTP with clinical, swallowing, and functional parameters. Results: In the correlation analysis, MTP was negatively correlated with disease duration (r = -0.396, p = 0.013) and VDS (r = -0.426, p = 0.007), and positively correlated with ALSFRS-R (r = 0.483, p = 0.002) and 6MWT (r = 0.396, p = 0.013). The bulbar (r = 0.367, p = 0.022) and gross motor (r = 0.486, p = 0.002) domains of the ALSFRS-R were correlated with MTP. Conclusion: Tongue pressure assessment can be used as a safe and easy tool to assess swallowing function in SBMA patients. Moreover, MTP reflects functional states, including activities of daily living and gait performance, showing it to be a potential biomarker for physical performance in SBMA.

Does polydeoxyribonucleotide has an effect on patients with tendon or ligament pain?: A PRISMA-compliant meta-analysis.

BACKGROUND: Pain in the tendons or ligaments is extremely common, accounting for 30% of the causes of visiting general practitioners. Polydeoxyribonucleotide (PDRN) is emerging as a new treatment for musculoskeletal pain. However, the effects of PDRN in patients with tendon or ligament pain are unclear. Therefore, this study aimed to determine the impact of PDRN in patients with tendon or ligament pain through a meta-analysis. METHODS: Electronic literature search of PubMed, Embase, SCOPUS, and Cochrane Library databases of all articles on PDRN treatment for patients with tendon or ligament pain published in the English language from inception until January 31, 2020. The search identified 262 citations. RESULTS: One randomized controlled trial and 3 retrospective observational studies were included. Pain due to tendon or ligament disorders showed significant improvement after PDRN injection (standardized mean difference [SMD] = -1.43, 95% confidence interval [CI] = -1.80 to -1.06, P < .00001). In the subanalysis of patients with rotator cuff tendinopathy, rotator cuff tendinopathy-induced pain significantly improved (SMD = -2.34, 95% CI = -3.61 to -1.07, P = .0003) after PDRN injection. However, there was no difference in shoulder pain and disability index score and strength of shoulder abduction in patients with rotator cuff tendinopathy (shoulder pain and disability index score, SMD = 1.16, 95% CI = -1.20 to 3.52, P = .34; strength of shoulder abduction, SMD = 0.42, 95% CI = -0.03 to 0.88, P = .07). CONCLUSION: Effective pain relief was achieved in patients with tendon or ligament disorders after PDRN injection. To more precisely determine this effect, a meta-analysis with a larger number of clinical trials is warranted.

Step-by-step inpatient rehabilitation for critical illness after coronavirus disease 2019: A CARE-compliant case report.

INTRODUCTION: Since the coronavirus disease (COVID-19) outbreak in Wuhan, China, in December 2019, COVID-19 has become a worldwide pandemic. Muscle weakness and deconditioning caused by COVID-19-induced critical illness requires rehabilitation. PATIENT CONCERNS: A 74-year-old male patient complained of general weakness after COVID-19, requiring ventilator treatment. DIAGNOSIS: He was confirmed as having COVID-19 using a polymerase chain reaction test. INTERVENTIONS: During admission in the intensive care unit, medical staff wearing level D protective equipment performed the bedside manual range of motion exercise. After a negative COVID-19 test, the patient was transferred to a general ward, where sitting balance training and pulmonary rehabilitation were additionally performed by rehabilitation therapists wearing protective gear. When the patient was able to stand up with support, standing balance training and sit-to-stand training were performed. OUTCOMES: After a month of rehabilitation, the patient could sit alone, but he needed help with standing balance. The Berg Balance Scale score improved from 0 to 4, and the Modified Barthel Index score improved from 8 to 18. He was able to breathe in room air without an oxygen supply. LESSONS: This case report shows an example of how safe and effective rehabilitation can be provided to COVID-19 patients.

Effect of leuprorelin in bulbar function of spinal and bulbar muscular atrophy patients: observational study for 1 year.

BACKGROUND: This study aimed to investigate the effect of androgen suppression therapy using leuprorelin focused on the bulbar function of patients with spinal and bulbar muscular atrophy (SBMA). METHODS: Genetically confirmed SBMA patients who consented to participate in this observational study were enrolled. Leuprorelin was subcutaneously injected every 12 weeks. Videofluoroscopic swallowing study was performed at baseline and after androgen suppression therapy for 1 year. The primary outcome measures were the changes in the vallecular residue and pyriform sinus residue. The videofluoroscopic swallowing study data were analyzed and interpreted by two experienced physiatrists. RESULTS: A total of 40 patients with SBMA were analyzed in this study. The inter-rater reliability testing showed good agreement for the pharyngeal residue (ICC = 0.84) and videofluoroscopic dysphagia scale (ICC = 0.75). The vallecular residue and pyriform sinus residue after swallowing 9 mL yogurt were significantly reduced (26.8 ± 22.6 to 14.6 ± 14.5, p < 0.001, 14.9 ± 16.9 to 7.6 ± 9.9, p < 0.001, respectively). The swallowing subscore of amyotrophic lateral sclerosis functional rating scale-revised improved after androgen suppression therapy (3.3 ± 0.5 to 3.5 ± 0.6, p = 0.041). CONCLUSIONS: Leuprorelin significantly reduced the pharyngeal residue in patients with SBMA after 1 year of treatment without any serious adverse events and longitudinal studies are needed to confirm these results.

Alterations of functional connectivity in auditory and sensorimotor neural networks: A case report in a patient with cortical deafness after bilateral putaminal hemorrhagic stroke.

RATIONALE: Cortical deafness is a rare auditory dysfunction caused by damage to brain auditory networks. The aim was to report alterations of functional connectivity in intrinsic auditory, motor, and sensory networks in a cortical deafness patient. PATIENT CONCERNS: A 41-year-old woman suffered a right putaminal hemorrhage. Eight years earlier, she had suffered a left putaminal hemorrhage and had minimal sequelae. She had quadriparesis, imbalance, hypoesthesia, and complete hearing loss. DIAGNOSES: She was diagnosed with cortical deafness. After 6 months, resting-state functional magnetic resonance imaging (rs-fMRI) and diffuse tensor imaging (DTI) were performed. DTI revealed that the acoustic radiation was disrupted while the corticospinal tract and somatosensory track were intact using deterministic tracking methods. Furthermore, the patient showed decreased functional connectivity between auditory and sensorimotor networks. INTERVENTIONS: The patient underwent in-patient stroke rehabilitation therapy for 2 months. OUTCOMES: Gait function and ability for activities of daily living were improved. However, complete hearing impairment persisted in 6 months after bilateral putaminal hemorrhagic stroke. LESSONS: Our case report seems to suggest that functional alterations of spontaneous neuronal activity in auditory and sensorimotor networks are related to motor and sensory impairments in a patient with cortical deafness.

Interhemispheric Functional Connectivity in the Primary Motor Cortex Assessed by Resting-State Functional Magnetic Resonance Imaging Aids Long-Term Recovery Prediction among Subacute Stroke Patients with Severe Hand Weakness.

This study aimed to evaluate the usefulness of interhemispheric functional connectivity (FC) as a predictor of motor recovery in severe hand impairment and to determine the cutoff FC level as a clinically useful parameter. Patients with stroke (n = 22; age, 59.9 ± 13.7 years) who presented with unilateral severe upper-limb paresis and were confirmed to elicit no motor-evoked potential responses were selected. FC was measured using resting-state functional magnetic resonance imaging (rsfMRI) scans at 1 month from stroke onset. The good recovery group showed a higher FC value than the poor recovery group (p = 0.034). In contrast, there was no statistical difference in FC value between the good recovery and healthy control groups (p = 0.182). Additionally, the healthy control group showed a higher FC value than that shown by the poor recovery group (p = 0.0002). Good and poor recovery were determined based on Brunnstrom stage of upper-limb function at 6 months as the standard, and receiver operating characteristic curve indicated that a cutoff score of 0.013 had the greatest prognostic ability. In conclusion, interhemispheric FC measurement using rsfMRI scans may provide useful clinical information for predicting hand motor recovery during stroke rehabilitation.

Are safe guards at trampoline parks safe enough?: A case report on a complete spinal cord injury after diving into a trampoline park foam pit.

RATIONALE: Recently, commercial indoor trampoline parks have been opened around the globe, and both the number of venues and the park users are increasing. Academic literatures have largely focused on home trampoline related injuries, and less is known about the injuries associated with trampoline parks due to the limited number of studies or cases reported. In this report, we present a complete spinal cord injury sustained at a commercial indoor trampoline park. PATIENT CONCERNS: A 26-year old male developed tetraplegia after plainly jumping on the trampolines and diving into one of the foam pits head first. DIAGNOSIS: C-spine CT revealed bilateral interfacetal dislocation on C6-7, and his C-spine MRI showed anterior translational injury at C6-7 with severe cord encroachment and complete discoligamentous complex disruption. He was diagnosed with complete spinal cord injury. INTERVENTIONS: The patient underwent 30 minutes each of physical therapy and occupational therapy twice a day for a total of 25 days of in-patient rehabilitation. Interventions included tilt table, passive range of motion exercises, functional electrical stimulation, sitting balance training, upper extremity strengthening exercise, and hand manipulation exercises. OUTCOME: Despite intensive rehabilitation and the patient's good spirit, there was no functional change in all physical examinations between evaluations at initial and at discharge. LESSONS: In conclusion, we aim to alert the risks associated with improper use of trampolines, promote safer entertainment environment, and aid in developing mandatory safety measures. We hope to alert the risks associated with improper use of trampolines, promote safer entertainment environment, and aid in developing mandatory safety measures.
