The assessment of the validity, safety, and utility of ChatGPT for patients with herniated lumbar disc: A preliminary study.

ChatGPT is perceived as a potential tool for patients diagnosed with herniated lumbar disc (HLD) to ask questions concerning desired information, with provision for necessary responses. In this preliminary study, we assessed the validity, safety, and utility of ChatGPT in patients with HLD. Two physicians specializing in the treatment of musculoskeletal disorders discussed and determined the 12 most frequently asked questions by patients with HLD in clinical practice. We used ChatGPT (version 4.0) to ask questions related to HLD. Each question was inputted into ChatGPT, and the responses were assessed by the 2 physicians. A Likert score was used to evaluate the validity, safety, and utility of the responses generated by ChatGPT. Each score for validity, safety, and utility was divided into 4 points, with a score of 4 indicating the most valid, safe, and useful answers and 1 point indicating the worst answers. Regarding validity, ChatGPT responses demonstrated 4 points for 9 questions (9/12, 75.0%) and 3 points for 3 questions (3/12, 25.0%). Regarding safety, ChatGPT scored 4 points for 11 questions (11/12, 91.7%) and 3 points for 1 question (1/12, 8.3%). Regarding utility, ChatGPT responses exhibited 4 points for 9 questions (9/12, 75.0%) and 3 points for 3 questions (3/12, 25.0%). ChatGPT demonstrates a tendency to offer relatively valid, safe, and useful information regarding HLD. However, users should exercise caution as ChatGPT may occasionally provide incomplete answers to some questions on HLD.

Treatment of Chronic Neck Pain in Patients with Forward Head Posture: A Systematic Narrative Review.

(1) Background: Forward head posture (FHP) is one of the most common cervical postural deviations and is characterized by head protrusion or forward head placement in relation to the shoulder in the sagittal plane. Patients with FHP often experience neck pain and disability. The aim of this study was to investigate whether treatment programs are effective in the management of neck pain in patients with FHP. (2) Methods: A MEDLINE (PubMed), Embase, Cochrane Library, and Scopus database search was conducted for English language articles on patients with chronic neck pain and FHP published until 12 April 2023. To identify potentially relevant articles, the following key search phrases were combined: 'forward head posture' and 'pain'. After searching, 2516 potentially relevant articles were identified. After reading the titles and abstracts and assessing their eligibility based on full-text articles, 16 articles were included in this review. (3) Results: Among the 16 studies that investigated the efficacy of treatment programs for managing chronic pain in patients with FHP, 11 investigated the effect of exercise programs, and 5 investigated the effect of manual therapy. Patients reported significant improvement in pain and disability after receiving treatment programs such as corrective postural exercises and special manual therapy techniques. (4) Conclusions: Various treatment programs, including postural corrective exercises and manual therapy, are beneficial for improving pain and disability in patients with FHP.

Treatment of Upper Crossed Syndrome: A Narrative Systematic Review.

BACKGROUND AND OBJECTIVES: Upper crossed syndrome (UCS) is a common musculoskeletal condition that is characterized by tightness and weakness of the muscles of the neck, shoulders, and upper back. The aim of this current study is to summarize and provide an overview of the treatment in patients with UCS. MATERIALS AND METHODS: A MEDLINE (PubMed), Cochrane library, Embase, Scopus, and Web of Science database search was conducted for English-language articles about upper crossed syndrome that were published until 19 January 2023. To identify potentially relevant articles, the following key search phrases were combined: "upper crossed syndrome", "upper cross syndrome", "diagnosis", and "treatment". A total of 233 articles were identified. After reading the titles and abstracts and assessing their eligibility based on the full-text articles, 11 articles were finally included in this review. The risk of bias (RoB) was assessed using RoB-2 and ROBINS-I for the randomized controlled trials (RCTs) and the non-randomized clinical trial (non-RCT), respectively. RESULTS: Among eleven studies that investigated the effect of treatment programs for UCS, five studies compared the therapeutic effect of exercise programs with controls, whereas six compared different rehabilitative treatment strategies, such as the muscle energy technique, soft-tissue mobilization, and stretching exercises. In addition, regarding the study design, ten studies were RCTs and only one study was a prospective observational study. CONCLUSIONS: Treatment programs including various types of exercises and techniques to correct an abnormal posture and restore neuromuscular imbalances are effective for decreasing pain and improving neck disabilities and postural deviations in patients with UCS.

Clinical Practice Guidelines for Oropharyngeal Dysphagia.

OBJECTIVE: Dysphagia is a common clinical condition characterized by difficulty in swallowing. It is sub-classified into oropharyngeal dysphagia, which refers to problems in the mouth and pharynx, and esophageal dysphagia, which refers to problems in the esophageal body and esophagogastric junction. Dysphagia can have a significant negative impact one's physical health and quality of life as its severity increases. Therefore, proper assessment and management of dysphagia are critical for improving swallowing function and preventing complications. Thus a guideline was developed to provide evidence-based recommendations for assessment and management in patients with dysphagia. METHODS: Nineteen key questions on dysphagia were developed. These questions dealt with various aspects of problems related to dysphagia, including assessment, management, and complications. A literature search for relevant articles was conducted using Pubmed, Embase, the Cochrane Library, and one domestic database of KoreaMed, until April 2021. The level of evidence and recommendation grade were established according to the Grading of Recommendation Assessment, Development and Evaluation methodology. RESULTS: Early screening and assessment of videofluoroscopic swallowing were recommended for assessing the presence of dysphagia. Therapeutic methods, such as tongue and pharyngeal muscle strengthening exercises and neuromuscular electrical stimulation with swallowing therapy, were effective in improving swallowing function and quality of life in patients with dysphagia. Nutritional intervention and an oral care program were also recommended. CONCLUSION: This guideline presents recommendations for the assessment and management of patients with oropharyngeal dysphagia, including rehabilitative strategies.

Diabetic peripheral neuropathy essentials: a narrative review.

BACKGROUND AND OBJECTIVE: Painful diabetic peripheral neuropathy (DPN) affects approximately 6-34% of all patients with diabetes. DPN-induced pain reduces the quality of life and makes daily activities difficult. Distal symmetric polyneuropathy (DSPN) is the most common type of DPN. Here we review the pathophysiology, diagnosis, and treatment of DPN. METHODS: A MEDLINE database (PubMed) search was conducted for English-language articles dealing with the effect of DPN that were published until April 1, 2022. To identify potentially relevant articles, the following key search phrases were combined: 'diabetes mellitus', 'diabetes', 'neuropathy', 'polyneuropathy', 'diabetic neuropathies', 'peripheral neuropathy', 'diabetic polyneuropathy', 'pathophysiology', 'diagnosis', and 'treatment'. KEY CONTENT AND FINDINGS: In a biopsy study of the sural nerve, damage to C and Aδ fibers were seen in patients who had recent onset of pain in their feet consisting of tingling, burning, and prickling, followed by initial demyelination/remyelination of large fibers. DPN is characterized by a pattern of distal-to-proximal axonal loss with symptoms. Hyperglycemia and dyslipidemia are the primary causes of DPN in patients with type 1 and 2 diabetes, respectively. The pattern of pain from DPN is described as "glove and stocking". DPN-induced pain is described as burning, electric, sharp, and dull aching with various pain intensities. DPN is a diagnosis of exclusion; diagnosis is made with a thorough medical history, physical examination, and clinical testing to rule out other causes of pain. Anticonvulsants (pregabalin and gabapentin), antidepressants (duloxetine, venlafaxine, and amitriptyline), opioids (tramadol, tapentadol, and oxycodone), and topical capsaicin are commonly administered to treat DPN. The combination of two or three of these pharmacological agents better resolves pain at lower doses and with fewer side effects. CONCLUSIONS: Clinicians should have sufficient knowledge of DPN to ensure its accurate diagnosis and appropriate treatment. This review provides clinicians with the necessary knowledge of the pathophysiology, diagnosis, and treatment of painful DPN.

Rehabilitation Program for Improved Musculoskeletal Pain in Gastrointestinal Endoscopists: Multicenter Prospective Cohort Study.

Background/Aims: This study aimed to develop a rehabilitation program for musculoskeletal pain experienced by gastrointestinal endoscopists and to investigate its usefulness. Methods: This was a multicenter cohort study. During the first 2 weeks, a questionnaire regarding daily workload and musculoskeletal symptoms was administered. Then, a rehabilitation program including equipment/posture correction and stretching was conducted during the remaining 6 weeks. Follow-up daily workload and musculoskeletal symptom surveys were distributed during the last 2 weeks. The program satisfaction survey was performed at the 6th and 8th weeks. Results: Among 118 participants (69 men), 94% (n=111) complained of musculoskeletal pain at baseline. Various hospital activities at baseline were associated with multisite musculoskeletal pain, whereas only a few workloads were correlated with musculoskeletal pain after the rehabilitation program. Follow-up musculoskeletal pain was negatively correlated with equipment/posture program performance; arm/elbow pain was negatively correlated with elbow (R=-0.307) and wrist (R=-0.205) posture; leg/foot pain was negatively correlated with monitor position, shoulder, elbow, wrist, leg, and foot posture. Higher performance in the scope position (86.8% in the improvement vs 71.3% in the aggravation group, p=0.054) and table height (94.1% vs 79.1%, p=0.054) were associated with pain improvement. An increased number of colonoscopy procedures (6.27 in the aggravation vs 0.02 in the improvement group, p=0.017) was associated with pain aggravation. Most participants reported being average (32%) or satisfied (67%) with the program at the end of the study. Conclusions: Our rehabilitation program is easily applicable, satisfactory, and helpful for improving the musculoskeletal pain experienced by gastrointestinal endoscopists.

Effectiveness of transcranial alternating current stimulation for controlling chronic pain: a systematic review.

Background: Chronic pain is common, disruptive, and often treatment-resistant. Hence, researchers and clinicians seek alternative therapies for chronic pain. Transcranial alternating current stimulation (tACS) is an emerging neuromodulation technique that non-invasively modulates neural oscillations in the human brain. tACS induces pain relief by allowing the neural network to restore adequate synchronization. We reviewed studies on the effectiveness of tACS in controlling chronic pain. Methods: The PubMed, SCOPUS, Embase, and Cochrane Library databases were systematically searched for relevant studies published until December 6, 2023. The key search phrase for identifying potentially relevant articles was [(Transcranial Alternating Current Stimulation OR tACS) AND pain]. The following inclusion criteria were applied for article selection: (1) studies involving patients with chronic pain; (2) tACS was applied for controlling pain; and (3) follow-up evaluations were performed to assess the degree of pain reduction after the application of tACS. Results: We identified 2,330 potentially relevant articles. After reading the titles and abstracts and assessing eligibility based on the full-text articles, we included four articles in our review. Among the included studies, tACS was used for fibromyalgia in one study, low back pain (LBP) in two studies, and migraine in one study. In the study on fibromyalgia, it did not show a better pain-reducing effect of tACS compared with sham stimulation. Two studies on LBP showed conflicting results. In migraine, tACS showed a positive pain-reducing effect 24-48 h after its application. Conclusion: There is insufficient research to draw a conclusive judgment on the effectiveness of tACS in controlling chronic pain. More studies across various chronic pain-related diseases are required for a definitive conclusion.

The effect of transcranial alternating current stimulation on functional recovery in patients with stroke: a narrative review.

Stroke is a common neurological disorder worldwide that can cause significant disabilities. Transcranial alternating current stimulation (tACS) is an emerging non-invasive neuromodulation technique that regulates brain oscillations and reshapes brain rhythms. This study aimed to investigate the effect of tACS on functional recovery in patients with stroke. The MEDLINE (PubMed), Cochrane Library, Embase, SCOPUS, and Web of Science databases were searched for English-language articles on tACS and stroke, published up to October 20, 2023. The following key search phrases were combined to identify potentially relevant articles: 'tACS,' 'transcranial alternating current stimulation,' 'stroke,' 'cerebral infarct,' and 'intracerebral hemorrhage.' The inclusion criteria for study selection were as follows: (1) studies involving patients with stroke and (2) studies that used tACS for functional recovery. A total of 34 potentially relevant studies were identified. Five articles were included in this review after reading the titles and abstracts and assessing their eligibility based on the full-text articles. Among the included studies, one investigated the improvement in overall functional status in patients with stroke after tACS, and two investigated the effect of tACS on motor function and gait patterns. Moreover, one study reported the efficacy of tACS on aphasia recovery, and one study evaluated the effect of tACS on hemispatial neglect. Our findings suggest that tACS improves functional recovery in patients with stroke. The application of tACS was associated with improved overall functional recovery, sensorimotor impairment, aphasia, and hemispatial neglect. The potential clinical application of tACS should be supported by high-quality, evidence-based studies.

Effectiveness of pulsed radiofrequency on the medial cervical branches for cervical facet joint pain.

BACKGROUND: Cervical facet joint pain (CFP) is one of the most common causes of neck pain and headache. Persistent CFP deteriorates the quality of life of patients and reduces their productivity at work. AIM: To investigate the effectiveness of pulsed radiofrequency (PRF) stimulation of cervical medial branches in patients with chronic CFP. METHODS: We retrospectively included 21 consecutive patients (age = 50.9 ± 15.3 years, range 26-79 years; male: female = 8:13; pain duration = 7.7 ± 5.0 mo) with chronic CFP, defined as ≥ 4 on the numeric rating scale (NRS). We performed PRF stimulation on the cervical medial branches. The outcomes of the PRF procedure were evaluated by comparing the NRS scores for CFP before treatment and 1 and 3 mo after treatment. Successful pain relief was defined as a ≥ 50% reduction in the NRS score at 3 mo when compared with the pretreatment NRS score. RESULTS: No patient had immediate or late adverse effects following PRF. The average NRS score for CFP decreased from 5.3 ± 1.1 at pre-treatment to 2.4 ± 0.6 at the 1 mo follow-up, and 3.1 ± 1.1 at the 3 mo follow-up. Compared to the NRS scores before PRF stimulation, those at 1 and 3 mo after PRF stimulation had significantly decreased. Eleven of the 21 patients (52.4%) reported successful pain relief 3 mo after the PRF procedure. PRF stimulation on cervical medial branches may be a useful therapeutic option to control chronic CFP. CONCLUSION: PRF stimulation of the cervical medial branches may be used as an alternative treatment method in patients with CFP. PRF can effectively alleviate CFP, and is safe to perform.

The effect of neurologic music therapy in patients with cerebral palsy: A systematic narrative review.

Background: Cerebral palsy (CP) is one of the most common causes of disability in children. It is characterized by impairment in motor function and coordination and difficulties in performing daily life activities. Previous research supports that neurologic music therapy (NMT) was effective in improving motor function, cognition, and emotional wellbeing in patients with various neurologic disorders. However, the benefit of NMT in patients with CP have not yet been thoroughly investigated. The aim of this review was to investigate the potential effect of NMT motor rehabilitation techniques for patients. Materials and methods: We searched articles published up to May 24, 2022 in PubMed, Embase, Scopus, Cochrane library, Web of science, and Ovid MEDLINEdatabases. We included studies that investigated the effect of NMT in patients with CP. Results: After search, 4,117 articles were identified using the search terms. After reading the titles and abstracts, 4,089 articles that did not meet our inclusion criteria were excluded. The remaining 28 articles which were assessed for eligibility. Finally, 15 studies were included in this systematic review. Among 15 studies that investigated the effect of NMT on patients with CP, 7 studies were on rhythmic auditory stimulation (RAS), 6 studies were on therapeutic instrumental music performance (TIMP), and 2 studies were on patterned sensory enhancement (PSE). Conclusions: Various techniques of NMT brings beneficial effects for gross and fine motor improvements in patients with CP. NMT techniques, such as RAS, TIMP, and PSE, may be a potential alternative rehabilitation strategy to enhance gross and fine motor skills for patients with CP.

At Least 5-Year Outcomes of Whiplash-Induced Chronic Neck Pain Following Response to Intra-Articular Facet Joint Corticosteroid Injection.

Objective: To investigate whether the response to intra-articular facet joint corticosteroid injection can determine the long-term prognosis (at least 5 years after injury) of whiplash injury-related neck pain sustained 3-12 months after injury. Methods: Of 65 patients who visited a university hospital for persistent whiplash injury-induced axial neck pain sustained 3-12 months after injury (numeric rating scale score ≥3) and had received intra-articular facet joint corticosteroid injection, 40 completed the telephone interview. We divided the patients into "good response group" (≥50% pain reduction at 1 month after the injection) and "poor response group" (<50% pain reduction at 1 month after the injection). We asked participants regarding the presence and degree of neck pain, its impact on work, and the use of oral pain medication or injection treatment. Results: A follow-up at least 5 years after the injury found that the number of patients with persistent whiplash injury-related neck pain was significantly lower in the good response group than in the poor response group. The number of patients taking oral pain medications prescribed by a medical doctor or receiving injection treatments in a pain clinic or hospital for neck pain was lower in the good response group than in the poor response group. The number of patients who answered that their work was affected by neck pain was lower in the good response group than in the poor response group. Conclusion: The response to intra-articular corticosteroid injection might be helpful in determining at least 5-year outcomes of chronic whiplash injury-induced pain.

The effectiveness of corticosteroid injection into cervical facet joint for managing whiplash-related neck pain.

BACKGROUND: Cervical facet joint (CFJ) pain is commonly seen after whiplash trauma, and is frequently refractory to physical therapy and oral medication. Previous studies have shown positive pain-reducing outcomes after intra-articular (IA) corticosteroid injection in patients with CFJ pain unrelated to injury. We evaluated the effectiveness of IA corticosteroid injection for managing whiplash-related CFJ pain. METHODS: We prospectively recruited 32 patients with chronic and persistent CFJ pain after whiplash trauma [≥3 on the Numeric Rating Scale (NRS)] despite physical therapy and oral medication. Under fluoroscopy guidance, we injected 10 mg (0.25 mL) of triamcinolone acetonide, mixed with 0.25 mL of 0.125% bupivacaine and 0.5 mL of normal saline. At 1 and 2 months after the injection, pain intensity was reassessed using the NRS. RESULTS: Thirty patients completed the study. The mean pretreatment NRS score was 5.4±1.7, while the mean NRS scores at 1 and 2 months after treatment were 3.9±1.7 and 4.0±1.6, respectively. The NRS scores at both follow-ups were significantly decreased compared to pretreatment scores (pretreatment vs. 1 month, P=0.002; pretreatment vs. 2 months, P=0.004). Furthermore, 8 patients (26.7%) reported pain relief of ≥50% 2 months after the treatment. CONCLUSIONS: In clinical practice, whiplash-induced CFJ pain is often refractory to physical therapy and oral medication, and clinicians have limited options to alleviate pain. We think that IA corticosteroid injection may serve as a management option for whiplash-related CFJ pain.

The Relationship Between Dysphagia and Pneumonia in Acute Stroke Patients: A Systematic Review and Meta-Analysis.

Background: Dysphagia is a common complication after stroke and is associated with the development of pneumonia. This study aimed to summarize the relationship between dysphagia and pneumonia in post-stroke patients. Materials and Methods: Articles published up to November 2021 were searched in the PubMed, Embase, Cochrane library, and Scopus databases. Studies that investigated the development of pneumonia in acute stroke patients with and without dysphagia were included. The methodological quality of individual studies was evaluated using the Risk Of Bias In Non-randomized Studies-of Interventions tool, and publication bias was evaluated using a funnel plot and Egger's test. Results: Of 5,314 studies, five studies were included in the meta-analysis. The results revealed that the incidence of pneumonia was significantly higher in the dysphagia group than in the non-dysphagia group (OR 9.60; 95% CI 5.75-16.04; p < 0.0001; I 2 = 78%). There was no significant difference in the mortality rate between the two groups (OR 5.64; 95% CI 0.83-38.18; p = 0.08; I 2 = 99%). Conclusion: Dysphagia is a significant risk factor for pneumonia after stroke. The early diagnosis and treatment of dysphagia in stroke patients are important to prevent stroke-associated pneumonia.

Short-term Effect of Repetitive Transcranial Magnetic Stimulation on Diabetic Peripheral Neuropathic Pain.

BACKGROUND: Approximately half of the patients with long-standing diabetes are known to have diabetic peripheral neuropathy (DPN). Pain from DPN deteriorates quality of life and hinders activities of daily living. OBJECTIVES: This study aimed to evaluate the short-term effect of high-frequency (10 Hz) repetitive transcranial magnetic stimulation (rTMS) on the left primary motor cortex (M1) for neuropathic pain in the lower extremities due to DPN. STUDY DESIGN: A randomized controlled trial. SETTING: The outpatient clinic of a single academic medical center. METHODS: In this randomized trial, 22 patients with DPN were randomly assigned to the rTMS group (10 Hz stimulation, 5 sessions) or the sham group. A numeric rating scale (NRS) was used to measure pain intensity before treatment and after one day and one week of treatment. Physical and mental health status were evaluated using the Short Form 36-Item Health Survey (SF-36), comprising 2 subscales (physical and mental component scores [PCSs and MCSs]), at one-week posttreatment. Of the 22 included patients, 20 (10 patients in each group) completed the study. RESULTS: In the rTMS group, the NRS score at one day and one week posttreatment was significantly lower than that at pretreatment. The SF-36 PCS and SF-36 MCS were significantly increased one week after the rTMS sessions. However, in the sham group, the NRS score, SF-36 PCS, and SF-36 MCS did not significantly change after the rTMS sessions. LIMITATIONS: The small number of included patients and no long-term follow-up. CONCLUSION: High-frequency rTMS on the left M1 may be useful for managing pain in the lower extremities due to DPN and may improve a patient's the quality of life.

Effect of Diabetes on Post-stroke Recovery: A Systematic Narrative Review.

Background: Patients with stroke often have comorbid diabetes. Considering its detrimental effects on brain function, diabetes may increase the risk of poor recovery. Methods: The aim of this review was to investigate the effect of diabetes on post-stroke recovery by a systematic review. Several specific aspects of post-stroke recovery, including activities of daily living (ADL), motor, cognitive, and quality of life (QOL) recovery, were examined. We searched the PubMed, SCOPUS, Embase, and Cochrane Library databases for relevant studies on the effect of diabetes on post-stroke recovery, published until May 26, 2021. A total of 52,051 potentially relevant articles were identified. After reading the titles and abstracts and assessing their eligibility based on full-text articles, 34 publications were included in this review. Results: Of 29 studies that assessed ADL recovery after stroke, 22 studies suggested that diabetes had a negative effect on recovery of ADL after stroke. Regarding motor recovery, only one out of four studies showed that diabetes had some effect on motor recovery after stroke. Of the two studies on cognitive recovery, one reported that diabetes was an independent predictor of poor cognitive recovery after stroke. Three studies on QOL reported that a poor QOL after stroke was associated with the presence of diabetes. Conclusions: The current review suggests that the post-stroke recovery of ADL seems to be poorer in patients with diabetes than patients without diabetes. Further, there are insufficient data to conclude the effect of diabetes on motor and cognitive recovery, but it may have some influence on the quality of life after stroke.

The Preventive Effect of Dysphagia Screening on Pneumonia in Acute Stroke Patients: A Systematic Review and Meta-Analysis.

(1) Background: Dysphagia is common in acute stroke patients and is a major risk factor for aspiration pneumonia. We investigated whether the early detection of dysphagia in stroke patients through screening could prevent the development of pneumonia and reduce mortality; (2) Methods: We searched the PubMed, Embase, Cochrane Library, and Scopus databases for relevant studies published up to November 2021. We included studies that performed dysphagia screening in acute stroke patients and evaluated whether it could prevent pneumonia and reduce mortality rates. The methodological quality of individual studies was evaluated using the Risk Of Bias In Non-randomized Studies of Interventions tool, and publication bias was evaluated by the funnel plot and Egger's test; (3) Results: Of the 6593 identified studies, six studies met the inclusion criteria for analysis. The screening group had a significantly lower incidence of pneumonia than the nonscreening group did (odds ratio (OR), 0.60; 95% confidence interval (CI), 0.42 to 0.84; p = 0.003; I2, 66%). There was no significant difference in mortality rate between the two groups (OR, 0.61; 95% CI, 0.33 to 1.13; p = 0.11; I2, 93%); (4) Conclusions: Early screening for dysphagia in acute stroke patients can prevent the development of pneumonia.

Transcranial Direct Current Stimulation for the Management of Neuropathic Pain: A Narrative Review.

BACKGROUND: Neuropathic pain (NP) is common and often resistant to conventional analgesics. Among different types of noninvasive brain stimulation techniques, transcranial direct current stimulation (tDCS) has been widely used to mitigate pain in patients with NP. OBJECTIVE: The aim of this study was to review the effects of tDCS on the management of various types of NP. STUDY DESIGN: Narrative review. METHODS: A PubMed search was conducted for articles published until October 1, 2020, using tDCS to treat NP. The key search phrase, transcranial direct current stimulation and pain, was used to identify potentially relevant articles. The following inclusion criteria were applied for article selection: (1) studies involving patients with NP and (2) studies that used tDCS to treat NP. Review articles were excluded from the analysis. RESULTS: A total of 524 potentially relevant articles were identified. After reading the titles and abstracts and assessing eligibility based on the full-text articles, 34 publications were included in our review. Overall, our results suggest that tDCS induced pain reduction in patients with NP due to stroke or spinal cord injury, multiple sclerosis, or trigeminal neuralgia. There is insufficient evidence to validate the efficacy of tDCS for treating other painful conditions, such as complex regional pain syndrome, phantom pain, or NP of various origins. LIMITATIONS: The review did not include studies indexed in databases other than PubMed. CONCLUSION: The results of the included studies suggest that tDCS may be beneficial in treating patients with NP due to stroke, spinal cord injury, multiple sclerosis, and trigeminal neuralgia. Further studies are recommended to validate the efficacy of tDCS in treating other types of NPs.

Clinical Practice Guideline for Postoperative Rehabilitation in Older Patients With Hip Fractures.

OBJECTIVE: The incidence of hip fractures is increasing worldwide with the aging population, causing a challenge to healthcare systems due to the associated morbidities and high risk of mortality. After hip fractures in frail geriatric patients, existing comorbidities worsen and new complications are prone to occur. Comprehensive rehabilitation is essential for promoting physical function recovery and minimizing complications, which can be achieved through a multidisciplinary approach. Recommendations are required to assist healthcare providers in making decisions on rehabilitation post-surgery. Clinical practice guidelines regarding rehabilitation (physical and occupational therapies) and management of comorbidities/complications in the postoperative phase of hip fractures have not been developed. This guideline aimed to provide evidence-based recommendations for various treatment items required for proper recovery after hip fracture surgeries. METHODS: Reflecting the complex perspectives associated with rehabilitation post-hip surgeries, 15 key questions (KQs) reflecting the complex perspectives associated with post-hip surgery rehabilitation were categorized into four areas: multidisciplinary, rehabilitation, community-care, and comorbidities/complications. Relevant literature from four databases (PubMed, EMBASE, Cochrane Library, and KoreaMed) was searched for articles published up to February 2020. The evidence level and recommended grade were determined according to the grade of recommendation assessment, development, and evaluation method. RESULTS: A multidisciplinary approach, progressive resistance exercises, and balance training are strongly recommended. Early ambulation, weigh-bearing exercises, activities of daily living training, community-level rehabilitation, management of comorbidities/complication prevention, and nutritional support were also suggested. This multidisciplinary approach reduced the total healthcare cost. CONCLUSION: This guideline presents comprehensive recommendations for the rehabilitation of adult patients after hip fracture surgery.
