The latest medical research on Rehabilitation Medicine

Investigating brain activation during motor imagery (MI) tasks in people with multiple sclerosis (pwMS) can increase the knowledge of the neural mechanisms underlying motor dysfunction in MS and, hopefully, aid in developing improved rehabilitation strategies.

To investigate brain activation in the supplementary motor area and premotor cortex via functional near-infrared spectroscopy (fNIRS) during a hand manipulation task, and comparing MI with actual practice (AP) in pwMS.

Each subject completed a sequence of 4 consecutive manual dexterity trials wearing an fNIRS device. The tasks included the following conditions: AP dominant hand, MI dominant hand, AP non-dominant hand, and MI non-dominant hand.

Twenty pwMS (mean Expanded Disability Status Scale = 4.75 [3.0-6.5]) and 20 healthy controls (HC) participated in the study. According to the fNIRS timeline course, a similar increase (compared with baseline) was observed in the relative oxygenated hemoglobin (HbO) concentration during the MI and AP tasks, which was immediately followed by a decrease (for either hand) in the pwMS and the HC groups. A difference in the relative HbO concentration between the HC and pwMS was detected solely when the 2 groups mentally replicated the manual dexterity task movements in the MI condition (dominant hand). The increase was higher in the HC group (P = .030).

Despite exhibiting manual dexterity difficulties, pwMS demonstrated comparable neural activation patterns as the HCs during MI tasks in regions associated with motor planning and complex movement control, thus, suggesting that deficits in manual dexterity among pwMS may not solely originate from impairments in the motor planning processes.

Telerehabilitation is a practical option for individuals with multiple sclerosis (MS) to engage in sustained physical activity without -visiting a rehabilitation facility. The aim of this systematic review was to evaluate the feasibility, effectiveness, safety, and adherence of exercise-based telerehabilitation as compared with usual care for MS patients.

A comprehensive literature search adhering to PRISMA guidelines was conducted, focusing on studies published in English since 2000. The systematic review protocol was registered in PROSPERO. The selection process involved strict criteria, including studies focusing on people with MS, telerehabilitation centred on regular exercise, a control group receiving usual care, valid exercise testing, and adherence to randomized controlled trial principles. Methodological quality was assessed using the TESTEX tool, ensuring rigour in study design and reporting.

Among the 281 records screened, 10 studies met the criteria. Telerehabilitation interventions varied in format and outcomes were assessed using diverse exercise tests and questionnaires. Despite variations, the studies collectively demonstrated promising feasibility and safety, with minimal withdrawals and minor adverse events. Effectiveness varied, with 5 out of 10 studies showing significant improvements in the intervention group. Adherence rates ranged from 38% to 100%.

In most of the assessed aspects, telerehabilitation is comparable to regular centre-based rehabilitation.

To corroborate findings suggesting that spinally targeted paired associative stimulation improves upper extremity motor function in chronic incomplete spinal cord injury.

Participants received paired associative stimulation, combining peripheral nerve stimulation and navigated transcranial magnetic stimulation towards 1 arm (16 1-h sessions during 4 consecutive weeks, targeting the 3 large nerves). Manual muscle testing (MMT) was performed in 23 muscles in each arm, at 3 time points (pre-stimulation, t0; the week following the stimulation period, t1; and 4-5 weeks post-stimulation, t2). Additionally, grip strength and changes in the Canadian Occupational Performance Measure were assessed.

The mean improvement in manual muscle testing scores in the targeted extremity was +0.49 at t1 (p = 0.078) and +0.55 at t2 (p = 0.062). Grip strength in the stimulated extremity increased by 3.2 kg at t1 and 3.4 kg at t2, and in the non-targeted extremity by 2.2 and 3.6 kg, respectively. Performance and satisfaction increased by 2.1/2.4 points at t1, and by 2.0/1.9 points at t2.

Paired associative stimulation improved motor function: at the group level, MMT of the stimulated hand (p = 0.06) and non-stimulated hand (p = 0.04). Most participants achieved clinically relevant improvement. Thus, the results corroborate prior studies. The method may complement conventional rehabilitation for improving upper extremity function in incomplete tetraplegia.

To investigate the combined effect of transcranial magnetic stimulation (TMS) and transcranial direct current stimulation on improving lower limb function in stroke patients.

169 post-stroke hemiplegia patients were randomly divided into 4 groups (control, transcranial direct current stimulation, transcutaneous auricular vagus nerve stimulation, and transcutaneous auricular vagus nerve stimulation combined with transcranial direct current stimulation) and evaluated using the Fugl-Meyer Assessment-Lower Extremity (FMA-LL), Timed Up-and-Go (TUG) test, Modified Barthel Index (MBI), Berg Balance Scale (BBS), gait parameters, and surface electromyography (sEMG).

Significant improvements in FMA-LL, MBI, BBS, TUG, gait parameters, and sEMG were noted in the intervention groups compared with the control, with the transcutaneous auricular vagus nerve stimulation combined with transcranial direct current stimulation group showing the most pronounced improvements. Differences in some outcomes were also notable between the transcutaneous auricular vagus nerve stimulation and transcranial direct current stimulation groups.

The combination of transcutaneous auricular vagus nerve stimulation and transcranial direct current stimulation effectively enhances gait, balance, and daily living activities in subacute stroke patients. These benefits are likely due to transcutaneous auricular vagus nerve stimulation activating the solitary and trigeminal nuclei and transcranial direct current stimulation stimulating the motor cortex. Wearable gait analysis systems and electromyography are valuable in clinical gait assessment for these patients.

Being struck by an object is a major cause of traumatic spinal cord injury in China. This study aims to investigate epidemiological characteristics of spinal cord injury caused by object strike.

This research analysed data from 435 cases of strike-induced spinal cord injury from 2013 to 2022. The collected information encompassed gender, age, level of neurological injury, surgical interventions, expense, occupation, and other relevant factors. χ2tests and Mann-Whitney U test were used with a statistical significance level of 0.05.

The male-to-female ratio was 11.8:1. The 30-44 age group was more likely to suffer from complete spinal cord injuries (70.5%). The predominant occupations were workers (58.9%) and farmers (15.2%). Manual labourers are usually injured in the workplace (89.4%) with a high surgical rate (95.3%).

Young and middle-aged males engaged in manual work constitute the primary demographic for strike-induced spinal cord injury. Safety education in workplaces such as construction sites and mines should be emphasized to reduce the occurrence of spinal cord injuries caused by object strikes.
