Understanding Antithrombotic Agents for Rehabilitation Therapy: A Comprehensive Narrative Review.

In rehabilitation medicine, attention must be paid to the medication. Among them, antithrombotic drugs are used for the initial treatment and secondary prevention of stroke, so as a basic knowledge, the pharmacological actions, characteristics, indications, and precautions for the use of antithrombotic drugs should be known. Antithrombotic agents are divided into antiplatelet agents and anticoagulants, and the appropriate antithrombotic agent is selected according to the main disease or condition. Antiplatelet agents include aspirin, clopidogrel, ticlopidine, prasugrel, ticagrelor, and cilostazol. Each antiplatelet agent has a different mechanism of action, characteristics, and indications, and should be prescribed with due consideration. Anticoagulants include heparin, synthetic Xa inhibitors, direct oral anticoagulants (DOACs), synthetic antithrombin agents, and warfarin. Knowledge of the mechanism of action, characteristics, and indications of each anticoagulant is necessary, as well as monitoring and dose adjustment. With regard to ischemic cerebrovascular disease (ICD) and antithrombotic agents, the first step is to classify cerebral infarction and to determine whether antiplatelet agents or anticoagulants should be used. Bleeding and recurrence prevention are important considerations in the selection of appropriate antithrombotic agents for the pathophysiology of ICD.

Two Cases Showing That Cilostazol Administration Leads to an Increase in Cerebral Blood Flow and Has a Positive Effect on Rehabilitation.

Cilostazol is a drug that has both antiplatelet and vasodilatory effects. To examine the effects of cilostazol on cerebral blood flow and rehabilitation following stroke, cilostazol was administered to two patients with chronic atherothrombotic cerebral infarction. In both patients, cilostazol administration effectively increased cerebral blood flow and promoted rehabilitation. Therefore, cilostazol was considered to be a useful agent for improving the clinical condition of patients suffering from chronic cerebral infarction. Further clinical studies on the effective use of cilostazol for rehabilitation in stroke patients are needed.

Repetitive facilitative exercise under continuous electrical stimulation for recovery of pure motor isolated hand palsy after infarction of the "hand knob" area: A case report.

PURPOSE: Pure motor isolated hand palsy (PMIHP) following infarction of the "hand knob" area is a rare entity in stroke. PMIHP usually recovers within the first few days, but there are rare cases where patients do not recover rapidly. Herein, we report a case of residual PMIHP in which repetitive facilitative exercise under concurrent low-amplitude continuous neuromuscular electrical stimulation ("RFE-under-cNMES") was introduced to improve hand function. CASE DESCRIPTION: A 65-year-old man with PMIHP (30 days after onset) participated in a rehabilitation program involving RFE-under-cNMES. This protocol followed an A1-B1-A2-B2 schedule, where the "A"-period consisted of RFE-under-cNMES ("A1," 2 weeks; "A2," 1 week), and the "B"-period consisted of 1-week conventional rehabilitation. OUTCOMES: The 5-week intervention promoted not only recovery from paralysis (8 points by the Fugl-Meyer Assessment), but also the ability to manipulate objects (13 points by the Action Research Arm test) and increased the subjective use of the affected upper limb during activities of daily living (2.88 points by the Motor Activity Log). Changes that exceeded the minimal clinically important difference occurred only in the RFE-under-cNMES period. CONCLUSIONS: The patient had improved outcomes. Further studies are required to determine the possibility of RFE-under-cNMES relieving motor paralysis in patients with PMIHP who do not recover rapidly.

Effects of sodium bicarbonate bath on the quality of sleep: An assessor-blinded, randomized, controlled, pilot clinical trial.

BACKGROUND: Sleep is fundamental to a healthy life, and sleep disorders are an important health issue in healthcare. Whole-body warm water bathing is a non-pharmacological, safe (non-invasive), and widely used method for comforting. Here, we explored the feasibility and preliminary effectiveness of sodium bicarbonate bath (SBB) on sleep quality. METHODS: Healthy adults without sleep disturbances were randomly assigned to shower baths (SHB), tap-water baths (TWB, placebo tablets), or SBB. All participants took a bath (shower, tap-water, or SBB) once a day for 10 min, after dinner, for 7 days. Sleepscan-derived sleep parameters, including total sleep time (TST), symptom questionnaires, and salivary α-amylase concentration were evaluated as outcome measures. RESULTS: Forty participants were enrolled (14, 13, and 13 in SHB, TWB, and SBB groups, respectively) and 38 participants completed the trial (13, 12, and 13, respectively). The recruitment, adherence, and completion rates were 90.9% (40/44), 95.0% (38/40), and 95.0% (38/40), respectively. The SBB group showed a significant increase (12.35 [mean]±10.07 [standard deviation] min) in the mean TST at 1-week post-intervention (p = 0.0041) than the SHB (-1.81 ± 14.58 min; p = 0.0231) and TWB (4.54 ± 10.97 min; p = 0.0377) groups. The TST scores at 1-week post-intervention, sleep onset latency, wake after sleep onset, and sleep efficiency were significantly different between the groups. Sleep satisfaction by questionnaire was significantly improved with intervention in the SBB group than that in the SHB and TWB groups. Salivary α-amylase levels significantly improved in the SBB and TWB groups than in the SHB group, with the change being greater in the SBB group. CONCLUSIONS: SBB for 7 days had positive effects that improved sleep quality of adults. Further studies are needed to examine the efficacy and safety of SBB for prolonged usage in people diagnosed with insomnia, using objective sleep measurements, and to investigate potential sleep-enhancing mechanisms of action.

Development of a Functional Bridge Test for Screening Impairments and Disabilities in Hemiplegic Patients with Acute Stroke while on the Bed.

Objectives: To provide a safe and appropriate out-of-bed program for stroke patients, screening for stroke-related functional impairments and disabilities should be performed in advance. However, few tools are available for clinical assessment of out-of-bed mobility while patients are still on bed. We sought to establish the validity and reliability of a newly developed Functional Bridge Test (FBT) for hemiplegic patients with acute stroke. Methods: This repeated-measures, observational study was conducted at a stroke care unit at an acute hospital. We assessed the validity of the FBT score, intra-rater and inter-rater reliabilities of the FBT, and concurrent validity of the FBT in stroke patients with hemiplegia. In addition to the original qualitative assessment, the FBT was also assessed quantitatively to evaluate the validity of the FBT score. Outcome measures included stroke severity, lower limb muscle strength, and basic mobility. Results: We enrolled 32 patients with acute stroke. The newly developed FBT score had high validity. Intra-rater and inter-rater reliabilities (weighted kappa coefficient, 95% confidence interval) showed almost perfect agreement (0.95, 0.88-1.00; 0.98, 0.94-1.00, respectively). The FBT score was significantly associated with stroke severity, physical function, and basic mobility. Conclusions: The FBT has sufficient validity and reliability for acute stroke patients with hemiplegia. The advantages of the FBT in a clinical setting are based on its ability to be quickly administered on a bed without the need for specialized equipment. The FBT may help in screening functional impairment and disability in hemiplegic patients with acute stroke before they resume out-of-bed activities.

Reliability of the portable gait rhythmogram in post-stroke patients.

BACKGROUND: Gait analysis, such as portable gait rhythmogram (PGR), provides objective information that helps in the quantitative evaluation of human locomotion. OBJECTIVE: The purpose of this study was to assess the reliability of PGR in post-stroke patients. METHODS: Two raters (A and B) examined 48 post-stroke patients. To assess intra-rater reliability, rater A tested subjects on three separate occasions (Days 1, 2, and 3). To assess inter-rater reliability, raters A and B independently tested participants on the same occasion (Day 3). RESULTS: There was no significant systematic bias between test occasions or raters. Intraclass correlation coefficient values were 0.93-0.97 for intra-rater reliability at both the comfortable speed and maximum speed, and 0.97-0.98 (comfortable speed) and 0.97-0.99 (maximum speed) for inter-rater reliability. The standard error was 1.25-1.49 (comfortable speed) and 1.62-1.77 (maximum speed) for intra-rater investigation, and 1.04-1.32 (comfortable speed) and 0.91-1.26 (maximum speed) for inter-rater investigation. At the 90% confidence level, the minimum detectable change ranged from 2.9-4.1%, and the error of an individual's score at a given time point ranged from ±2.1-2.9%. CONCLUSIONS: Based on this excellent reliability of the PGR in post-stroke patients, it can be recommended as a simple test of gait analysis in this population.

Use of an arm weight-bearing combined with upper-limb reaching apparatus to facilitate motor paralysis recovery in an incomplete spinal cord injury patient: a single case report.

[Purpose] Training using an arm weight-bearing device combined with upper-limb reaching apparatus to facilitate motor paralysis recovery, named the "Reaching Robot", as well as Repetitive Facilitation Exercise were applied to a patient with severe impairment of the shoulder and elbow due to incomplete spinal cord injury and the effects were examined. [Subjects and Methods] A 66-year-old man with incomplete spinal cord injury participated in an upper extremity rehabilitation program involving a Reaching Robot. The program was comprised of active motor suspension, continuous low amplitude neuromuscular electrical stimulation and functional vibratory stimulation, as well as Repetitive Facilitation Exercise combined with continuous low amplitude neuromuscular electrical stimulation. This protocol used a crossover design following an A1-B1-A2-B2. "A" consisted of 2 weeks of Repetitive Facilitation Exercise, and "B" consisted of 2 weeks of Reaching Robot training. [Results] Improvements were observed after all sessions. Active range of motion for shoulder flexion improved after 2 weeks of Reaching Robot sessions only. There were no adverse events. [Conclusion] Reaching Robot training for severe paretic upper-extremity after incomplete spinal cord injury was a safe and effective treatment. Reaching Robot training may be useful for rehabilitation of paretic upper-extremity after incomplete spinal cord injury.
