Effects of Tai Chi Yunshou on upper-limb function and balance in stroke survivors: A systematic review and meta-analysis

Background and purposePhysical rehabilitation plays an important role in the recovery of motor function after a stroke. This study aimed to evaluate the effects of Tai Chi Yunshou (TCY), a form of physical therapy, on upper-limb function and balance in stroke survivors.MethodsMEDLINE, Embase, CENTRAL and five Chinese databases were retrieved from inception to July 1, 2020 (updated on March 31, 2022). Randomized controlled trials of TCY versus no-treatment for stroke were included. The RoB-2 was used to evaluate the quality of included studies. Upper-limb motor impairment, balance, and activities of daily living (ADLs) were measured by Fugl-Meyer Assessment Upper Extremity Scale (FMA-UE), Berg Balance Scale (BBS), and Barthel Index (BI), respectively. Data synthesis was performed using RevMan (v5.3), and expressed as mean difference (MD) with 95% confidence intervals (CI).ResultsSeven studies with 529 participants were included. Compared with no-treatment, TCY improved FMA-UE (MD = 7.31, 95% CI: 5.86–8.77, minimal clinically important difference [MCID]: 9–10), BBS (MD = 4.68, 95% CI: 0.28–9.07, MCID: 4), and BI (MD = 4.12, 95% CI: 3.28–4.96, MCID: 1.85) in stroke survivors.ConclusionTCY may benefit balance and ADLs in rehabilitation after a stroke, but it may not improve upper-limb function clinically.

Intravenous thrombolysis for acute ischemic stroke with extended time window

Background:Intravenous thrombolysis (IVT) is an effective way for treating acute ischemic stroke (AIS). However, its effects have not been established among AIS patients with unclear stroke symptoms or with stroke onset for >4.5 h.Methods:We searched PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials and Google Scholar databases for randomized controlled trials that compared IVT (IVT group) and placebo or usual care (control group [CG]) in AIS patients with disease onset for >4.5 h. The outcomes of interest included the favorable functional outcome (defined as modified Rankin Scale [mRS] scores 0–1) at 90 days, the functional independence (defined as mRS scores 0–2) at 90 days, proportion of patients with symptomatic intracerebral hemorrhage (sICH) and death at 90 days. We assessed the risk of bias using the Cochrane tool. Pre-specified subgroup analyses were performed by age (≤70 years or >70 years), National Institute of Health Stroke Scale (NIHSS, ≤10 or >10) and time window (4.5–9.0 h or >9.0 h).Results:Four trials involving 848 patients were eligible. The risk of bias of included trials was low. Patients in the IVT group were more likely to achieve favorable functional outcomes (45.8% vs. 36.7%; OR 1.48, 95% CI 1.12–1.96) and functional independence (63.8% vs. 55.7%; OR 1.43, 95% CI 1.08–1.90) at 90 days, but had higher risk of sICH (3.0% vs. 0.5%; OR 5.28, 95% CI 1.35–20.68) at 90 days than those in the CG. No significant difference in death at 90 days was found between the two groups (7.0% vs. 4.1%; OR 1.80; 95% CI 0.97–3.34).Conclusions:Use of IVT in patients with extended time window may improve their functional outcomes at 90 days, although IVT may induce increased risk of sICH. Care of these patients should well balance the potential benefits and harms of IVT.     

Electroacupuncture for Reflex Sympathetic Dystrophy after Stroke: A Meta-Analysis

Background: Reflex sympathetic dystrophy (RSD) is the common complication among stroke and cerebral injury patients, which is lack of safe and effective treatment. Electroacupuncture (EA) may potentially be a reliably therapy, but the evidence is insufficiency. Methods: Cochrane Library, MEDLINE, Embase, Chinese National Knowledge Infrastructure, Wan Fang Data, the Chinese Biology Medicine disc, etc., were searched, until July 20, 2018. We included random control trials that contrast EA with conventional rehabilitation therapy for the treatment of RSD. Main outcomes were visual analog scale score and Fugl-Meyer upper limb motor function scoring scale, other outcomes such as Barthel index, and hand swelling score were also collected. Data in included studies were extracted into an excel and pooled by Stata/MP 14.1. Results: We incorporated 13 studies involving 1040 RSD patients and outcomes were from 2 to 6 weeks' follow-up. The analgesic effect between 2 groups had statistically significant difference (weighted mean difference [WMD] = ?1.122, 95% confidence interval [CI] [?1.682 to ?.562], P?=?.000], a statistical difference existed in improving dysfunction between 2 groups: (WMD?=?6.039, 95% CI [2.231?.916], P?=?.000). EA groups had a better effect on improving activities of daily life abilities (WMD?=?12.170, 95% CI [6.657?17.682], P < .00011] and better detumescence effect (WMD = ?.800, 95% CI [?1.972 to ?.212], P = .000] contrast to conventional rehabilitation therapy. Conclusions: This meta-analysis supports that EA has a positive effect on alleviating pain, improving limb dysfunction, and promoting activities of daily living. On account of moderate-quality random control trials and high heterogeneity, further high-quality studies are imperative to optimize the EA treatment program.

Moxibustion is an Alternative in Treating Knee Osteoarthritis: The Evidence From Systematic Review and Meta-Analysis

Knee osteoarthritis (KOA) is a common disorder in elderly. There is no known cure for KOA, and thus therapeutic strategies of alleviating symptoms are increasingly emphasized. Moxibustion has been widely used to treat KOA; however, results are inconclusive. The aim of our study is to critically reassess the effects of moxibustion on KOA.We searched PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), and Chinese Biomedical Literature database (CBM) through 25 November 2015. Two independent reviewers selected studies and abstracted information, as well as assessed the risk of bias using Cochrane risk of bias tool. The random-effects meta-analyses were performed based on abstracted data.We initially captured 163 citations and added 4 records through checking review. After critical appraisal, 13 RCTs were included. Meta-analyses indicated that moxibustion is not statistically different from oral drug in improving the response rate (MD = 1.09; 95% CI = 1.00, 1.20; P = 0.05), alleviating pain and improving physical function. Our meta-analysis also found that moxibustion is superior to usual care and sham moxibustion in reducing WOMAC score (MD = 7.56; 95% CI = 4.11, 11.00; P = 0.00), pain and function, as well as increasing QoL. Moreover, most AEs caused by moxibustion can heal without medical care.We concluded that moxibustion treatment is equal to the oral drugs and intra-articular injections and may be an alternative in treating patients with KOA.     

Thread embedding acupuncture for herniated intervertebral disc of the lumbar spine: A multicenter,randomized, patient-assessor-blinded,controlled, parallel,clinical trial

Backgroundand purpose: Although several studies have reported that thread embedding acupuncture (TEA) is effective for lumbar herniated intervertebral disc (LHIVD), the evidence remains limited because previous studies had a high risk of bias. This study aimed to investigate the efficacy and safety of TEA for LHIVD through a rigorously designed trial.Materials and methodsThis was a randomized, patient-assessor-blinded, sham-controlled trial. Participants were screened according to eligibility criteria, and 70 patients with LHIVD were randomly allocated to the TEA and sham TEA (STEA) groups in a 1:1 ratio. Both groups received TEA or STEA treatment at 23 acupoints once per week for eight weeks. Changes in low back pain, radiating pain, Oswestry disability index, Roland–Morris disability questionnaire, EuroQol 5–Dimensions 5–Levels, and global perceived effect were measured at baseline and at 4, 8, 12, and 16 weeks after screening and compared between the two groups.ResultsTEA showed no significant difference in all outcomes compared to STEA immediately after eight weeks of treatment. After an additional eight weeks of follow-up, TEA showed a more significant effect on the low back pain than STEA (p < 0.05) and showed a better tendency in maintaining or enhancing the improvement of radiating pain, function, and quality of life even after the end of treatment. No serious adverse events were observed.ConclusionTEA is effective in improving low back pain in patients with LHIVD and may help improve function and quality of life, especially in the long term.     

Effects of dry needling plus exercise therapy on post-stroke spasticity and motor function: A case report

Background and purposeThe use of dry needling (DN) with other treatments may be more beneficial in managing post-stroke spasticity. We report the effects of DN plus exercise therapy (ET) on wrist flexor spasticity.Patient presentationThe patient was a 45-year-old man with an 8-year history of stroke. The outcome measures included the Modified Modified Ashworth Scale (MMAS), H_max/M_max ratio, H-reflex latency, Action Research Arm Test (ARAT), Fugl-Meyer Assessment (FMA), and range of motion (ROM) which were assessed before (T1), after (T2), and after 3-week follow-up (T3).ConclusionThe MMAS was improved at T2 from “3” to “2”. The H_max/M_max decreased from 0.77 to 0.53 at T3. The H-reflex latency increased from 15.4 ms to 18.5 ms at T3. The wrist active and passive ROM increased ∼30° and ∼20° at T2, respectively.A 4-session DN plus ET may improve spasticity and ROM. No meaningful improvement was observed in function.
