Article Synopsis
  • * A rare case is presented of a tile installer who experienced unilateral deep peroneal neuropathy after extended squatting, which was diagnosed using ultrasonography.
  • * The case highlights the importance of using ultrasonography in diagnosing nerve issues when other tests, like electrodiagnostics, yield unexpected results.

Background: Transcranial direct current stimulation (tDCS) is a therapeutic tool for improving post-stroke gait disturbances, with ongoing research focusing on specific protocols for its application. We evaluated the feasibility of a rehabilitation protocol that combines tDCS with conventional gait training.

Methods: This was a randomized, double-blind, single-center pilot clinical trial.

Rationale: Joubert syndrome (JS) is a rare genetic disorder that presents with various neurological symptoms, primarily involving central nervous system dysfunction. Considering the etiology of JS, peripheral nervous system abnormalities cannot be excluded; however, cases of JS accompanied by peripheral nervous system abnormalities have not yet been reported. Distinct radiological findings on brain magnetic resonance imaging were considered essential for the diagnosis of JS.

Orthostatic tremor (OT) is an uncommon progressive movement disorder that involves a leg tremor when standing or weight bearing. Additionally, OT can accompany other medical or neurodegenerative disorders. In this article, we report an unusual case of OT after trauma in an 18-year-old male patient whose symptoms of OT have been resolved after a multimodal therapeutic approach, including botulinum toxin injection.

Background: Many studies have reported that exercise is effective for fibromyalgia and various types of exercise are recommended. However, most of exercises lack evidence for fibromyalgia symptoms. We aimed to examine the effect of core muscle strengthening exercise compared to general stretching exercise in fibromyalgia patients.

Transcranial alternating current stimulation (tACS) is a neuromodulation procedure that is currently studied for the purpose of improving cognitive function in various diseases. A few studies have shown positive effects of tACS in Alzheimer's disease (AD). However, the mechanism underlying tACS has not been established.

Spinocerebellar ataxia (SCA) is a hereditary neurodegenerative disorder that presents as ataxia. Due to the decline in balance, patients with SCA often experience restricted mobility and a decreased quality of life. Thus, many studies have emphasized the importance of physiotherapies, including gait training, in SCA patients.

Rationale: Pelizaeus-Merzbacher disease (PMD) is an X-linked recessive trait and a rare disease characterized by abnormal myelin formation in the central nervous system. Since Pelizaeus and Merzbacher reported the pathology of PMD in the 1990s most studies have examined pharmacological treatments. No studies have reported the effects of rehabilitation on patients with PMD aimed at improving their functional abilities.

Objective: To test the hypothesis that a longer duration of phase II cardiac rehabilitation is required to recover the exercise capacity of elderly patients compared to younger patients.

Methods: We retrospectively reviewed and analyzed the medical records of patients who were referred to our cardiac rehabilitation (CR) center and underwent percutaneous coronary intervention for acute myocardial infarction (AMI). A total of 70 patients were enrolled who underwent an exercise tolerance test (ETT) 3 weeks after the occurrence of an AMI (T0), 6 weeks after the first ETT (T1), and 12 weeks after the first ETT (T2).

Rationale: Spinal cord injury (SCI) patients who experience difficulties with independent walking use gait-assistive devices such as a cane, walker, or wheelchair. Few studies have explored gait patterns or cardiopulmonary function in chronic SCI patients after powered exoskeleton training. We investigated whether the cardiopulmonary function of a patient with an incomplete chronic cervical SCI and a hemiplegic gait pattern could be improved by walking training using a powered exoskeleton (Angelegs).

Objective: To compare a center-based cardiac rehabilitation (CR) program with a home-based CR program in terms of improving obesity related index and cardiopulmonary exercise capacity after the completing a phase II CR program.

Methods: In this study, there were seventy-four patients with acute myocardial infarction after percutaneous coronary intervention who were analyzed. Patients with mild to moderate risk (ejection fraction >40%) were included in the group.

Objective: To determine whether heart rate recovery (HRR) following an exercise tolerance test (ETT) is correlated with a changing ratio of peak oxygen consumption (VO) and maximal metabolic equivalents (MET).

Methods: A total of 60 acute myocardial infarction (AMI) patients who underwent ETT at both assessment points - 3 weeks (T0) after the AMI attack and 3 months after T0 (T1) were included. After achieving a peak workload, the treadmill was stopped with a 5-minute cooldown period, and the patients recovered in a comfortable and relaxed seated position.

Background: Exercise intensity is a particularly important determinant of physiological responses to exercise training in patients with acute myocardial infarction. Heart rate (HR) is commonly used as a practical way of prescribing and monitoring exercise as specific intensities based on a linear relationship between the percentage of maximum HR (%HR) and the percentage of maximum oxygen consumption (%VO) regardless of age, gender, or exercise mode.

Objective: To examine the change in variability in the correlation between %HR and %VO after acute myocardial infarction.

Article Synopsis
  • - DiGeorge Syndrome is a rare condition linked to deletions on chromosome 22 that can cause a variety of health issues like heart defects, facial anomalies, and cognitive challenges.
  • - A case study involved a 15-year-old girl with DiGeorge Syndrome who underwent cardiac rehabilitation three times a week for six weeks, with no measurable improvement in her aerobic capacity, but she felt her daily activity performance had improved.
  • - The findings suggest that despite limitations often placed on adolescents with congenital heart defects, cardiac rehabilitation should be encouraged as a valuable health promotion strategy.

Objective: To quantify changes in cardiopulmonary function using a lower body positive pressure supported (LBPPS) treadmill during the exercise tolerance test (ETT) in healthy subjects before applying the LBPPS treadmill in patients with gait problems.

Methods: We evaluated 30 healthy subjects who were able to walk independently. The ETT was performed using the Modified Bruce Protocol (stages 1-5) at four levels (0%, 40%, 60%, and 80%) of LBPPS.

Objective: To investigate the effect of pulsed radiofrequency (PRF) applied proximal to the injured peripheral nerve on the expression of tumor necrosis factor-α (TNF-α) in a neuropathic pain rat model.

Methods: Nineteen male Sprague-Dawley rats were used in the study. All rats underwent chronic constriction injury (CCI) procedure.

A 37-year-old man with a right transfemoral amputation suffered from severe phantom limb pain (PLP). After targeting the affected supplementary motor complex (SMC) or primary motor cortex (PMC) using a neuro-navigation system with 800 stimuli of 1 Hz repetitive transcranial magnetic stimulation (rTMS) at 85% of resting motor threshold, the 1 Hz rTMS over SMC dramatically reduced his visual analog scale (VAS) of PLP from 7 to 0. However, the 1 Hz rTMS over PMC failed to reduce pain.

A 48-year-old male patient had an injection of industrial silicone under the penile skin for augmentation by non-medical practitioners a week before. There was complete necrosis of the dorsal part of the penile skin and soft tissue. In a penile magnetic resonance image, big masses of silicone under the penile skin were found and a part of the silicone was partially exposed.
