Tai chi for upper limb rehabilitation in stroke patients: the patient's perspective

Effects of body weight-supported Tai Chi Yunshou training on upper limb motor function in stroke patients: A three-arm parallel randomized controlled trial

OBJECTIVES

To form a unique body weight support-Tai Chi Yunshou (BWS-TCY) training method, apply it to the treatment of upper limb dysfunction after stroke, and provide a new safe and effective treatment method for the clinic.

METHODS

A total of 93 subjects were recruited and randomly divided into conventional rehabilitation treatment (CRT) group, BWS-TCY group and traditional robot-assisted training (RAT) group in equal proportions. Subjects in the CRT group received 60 minutes of CRT daily. Subjects in the BWS-TCY group received 30 minutes of CRT and 30 minutes of BWS-TCY. Subjects in the RAT group received 30 minutes of CRT and 30 minutes of RAT. All interventions were conducted 5 days per week for 12 weeks. Outcome assessments included the Fugl-Meyer Upper Extremity Motor Function Assessment (FMA-UE), Wolf Motor Function Test (WMFT), absolute angular error (AAE), joint range of motion (JMA), modified Barthel Index (MBI), and stroke-related quality of life. Table (SS-QOL). Outcome measures were assessed at baseline, 4 weeks, 8 weeks, and 12 weeks later, and statistical analyzes were performed using two-way repeated measures analysis of variance.

RESULTS

After 12 weeks of intervention, significant improvements were observed in all evaluation indicators for the three groups of subjects compared to before the intervention. The upper limb motor function (FMA-UE and WMFT) and proprioception (AAE) showed time effects, time × group interaction effects, and group effects. When comparing the groups, the FMA-UE in the BWS-TCY group, as well as the WMFT and MBI, showed statistically significant differences compared to the CRT group (P<0.05), but not statistically significant compared to the RAT group (P>0.05). The AAE of the BWS-TCY group showed no statistical difference (P>0.05) when compared to the CRT group and RAT group. Furthermore, a time effect was observed on the rotation direction (P<0.05), and pairwise comparison between groups revealed that the BWS-TCY group performed better than both the CRT group and the RAT group. After 12 weeks of intervention, there were time effects and interaction effects between BWS-TCY and daily living activities (MBI) and quality of life (SS-QOL), but no group effect was observed. There was no statistical difference between the two groups in SS-QOL. However, there was a statistical difference (P<0.01) in MBI between the two groups.

CONCLUSIONS

The 12-week BWS-TCY intervention has been shown to effectively improve upper limb motor function.

A scoping review of mind-body therapies for people with persistent pain after stroke

PURPOSE

Persistent pain post-stroke is common; however, non-medical management options remain under-researched. This scoping review sought to identify and summarise existing literature regarding mind-body therapies for people with persistent pain post-stroke, examine pain and pain-related biopsychosocial outcomes, and identify areas for future research.

MATERIALS AND METHODS

This review followed PRISMA and JBI guidelines; the protocol was registered on Open Science Framework. Five electronic databases (PubMed, EMBASE, CINAHL, PsycINFO, Web of Science) were searched from 1992 until 19th August 2024. Primary studies of any design evaluating mind-body therapies in adults with persistent pain post-stroke, published in English in peer-reviewed journals, were eligible. Findings were narratively summarised by study, sample, and mind-body therapy characteristics.

RESULTS

Twenty-one studies comprising 458 adults with various post-stroke pain presentations were included. Only 10 studies specifically targeted stroke pain; the remainder primarily incorporated pre-post measures of pain in a heterogenous stroke sample (with and without pain). Studies varied in their levels of evidence, sample characteristics, mind-body therapies, and biopsychosocial outcome measurement. Nonetheless, improvements in pain and pain-related biopsychosocial outcomes were consistently reported.

CONCLUSION

Limited, lower-quality research suggests improved pain and biopsychosocial outcomes. However, further rigorous research exploring feasibility, safety, efficacy, optimal dosage, format, and setting is recommended.

The effect of body weight-supported Tai Chi Yunshou on upper limb motor function in stroke survivors based on neurobiomechanical analysis: a four-arm, parallel-group, assessors-blind randomized controlled trial protocol

Introduction

A series of functional disorders commonly occur after stroke, of which upper limb dysfunction is the most difficult to recover. The upper limb rehabilitation effect of Tai Chi Yunshou(TCY) in the later stage of stroke has been confirmed by research. Body weight support-Tai Chi Yunshou (BWS-TCY) is based on TCY exercise and robotic exoskeletons offers most flexibility in deweighting and control strategy. This study is aimed to explore the effect of BWS-TCY on upper limb motor function in stroke based on neurobiomechanics.

Methods and analysis

A single-blind randomized controlled trial will be conducted on 36 stroke survivors who will be randomly assigned to three groups: experimental group, control group A and control group B. In addition, 12 healthy elderly people will be recruited into the healthy control group. Those in the experimental group will receive 20 min of CRT and 20 min of BWS-TCY training, while participants in the control group A will receive 20 min of CRT and 20 min of Robot-assisted training. Participants in the control group B will undergo 40 min of Conventional rehabilitation training (CRT) daily. All interventions will take place 5 days a week for 12 weeks, with a 12-week follow-up period. No intervention will be carried out for the healthy control group. Upper limb function will be assessed before and after the intervention using various rating scales (Fugl-Meyer Assessment, Wolf Motor Function Test, etc.), as well as neurobiomechanical analyses (surface electromyography, functional near-infrared brain function analysis system, and Xsens maneuver Capture System). Additionally, 10 healthy elderly individuals will be recruited for neurobiomechanical analysis, and the results will be compared with those of stroke survivors.

Discussion

The results of this study will offer initial evidence on the effectiveness and feasibility of BWS-TCY as an early intervention for stroke rehabilitation. Positive findings from this study could contribute to the development of guidelines for the use of BWS-TCY in the early stages of stroke.

Ethics and dissemination

This study has been approved by the Research Ethics Committees of the seventh People's Hospital Affiliated to Shanghai University of Traditional Chinese Medicine (Study ID: 2022-7th-HIRB-022). The results of the study will be published in a peer-reviewed journal and presented at scientific conferences.

Neurobiomechanical mechanism of Tai Chi to improve upper limb coordination function in post-stroke patients: a study protocol for a randomized controlled trial

BACKGROUND

Upper limb dysfunction seriously affects the ability of stroke patients to perform activities of daily living. As a popular exercise therapy, Tai Chi may become an alternative intervention. However, the neurophysiological mechanism by which Tai Chi improves upper limb dysfunction in stroke patients is still unclear, which limits its further promotion and application. Therefore, conducting a strict randomized clinical trial is necessary to observe how Tai Chi affects upper limb dysfunction in stroke patients and to explore its neurophysiological mechanism.

METHODS/DESIGN

This report describes a randomized, parallel-controlled trial with distributive concealment and evaluator blinding. A total of 84 eligible participants will be randomly assigned to the Tai Chi group or the control group in a 1:1 ratio. The participants in the Tai Chi group will receive 4 weeks of Tai Chi training: five 60-min sessions a week for a total of 20 sessions. The participants in the control group will not receive Tai Chi training. Both groups will receive medical treatment and routine rehabilitation training. The primary outcome measure is the mean change in the Fugl-Meyer Assessment Upper Extremity (FMA-UE) scale score between baseline and 4 weeks; the secondary outcomes are the mean changes in kinematic characteristics and the Wolf Motor Function Test (WMFT) and Stroke Impact Scale (SIS) scores. In addition, the corticomuscular coupling level and near-infrared brain functional imaging will be monitored to explore the mechanism by which Tai Chi improves upper limb function of stroke patients.

DISCUSSION

This randomized controlled trial will examine the effectiveness of Tai Chi in stroke patients with upper limb dysfunction and explore the neurophysiological mechanism. Positive results will verify that Tai Chi can improve upper limb function of stroke patients.

Effects of health qigong exercise on upper extremity muscle activity, balance function, and quality of life in stroke patients

Introduction

This study explored the effects of Qigong exercises on upper extremity muscle activity, balance function, and quality of life in stroke patients.

Methods

A total of 30 stroke patients were randomly allocated to either control group or Qigong group. In the Qigong group, participants completed an intervention of Qigong Baduanjin over 8 weeks. Data on the electromyographic activities of the biceps brachii muscle, triceps brachii muscle, and muscle coordination were obtained using surface electromyography and the co-contraction ratio (CCR). Data on balance were obtained using the PK254P balance function detection system. Quality of life was measured using the brief version of the World Health Organization Quality of Life scale.

Results

The results for the Qigong group showed a significant difference in CCR of the triceps brachii muscle (p < 0.01). Concerning balance (assessed using the open-eye test), there was a significant decrease (p < 0.05) in Y-axis trajectory deviations and the Y-axis speed in the Qigong group. In the closed-eye test, the peripheral area of the Qigong group was significantly lower than that of the control group (p < 0.05). Significant differences were also observed in physical health (p < 0.05), psychological health (p < 0.01), environment (p < 0.01), and the total scores for quality of life (p < 0.01) in the Qigong group.

Discussion

We conclude that Qigong exercises improve the quality of life in stroke patients and have positive effects on the coordination of limb extremities and balance function.

Stroke Survivors' Personal Efficacy Beliefs and Outcome Expectations of Tai Chi Exercise: A Qualitative Descriptive Study

Prior qualitative research conducted among stroke survivors to explore the potential benefits and challenges of participating in tai chi exercise during stroke recovery is limited to those without depression. A qualitative descriptive approach was used. Social Cognitive Theory and Complex Systems Biology provided the theoretical framework, with focus group interview data collected from stroke survivors after participation in a tai chi intervention. Due to COVID-19, the focus group interview was conducted via online video conferencing. Content analysis of the de-identified transcript was conducted with a-priori codes based on the theoretical framework and inductive codes that were added during the analysis process. Lincoln and Guba's criteria were followed to ensure trustworthiness of the data. Community-dwelling stroke survivors (n = 7) participating in the focus group interviews were on average 68 years old, mainly retired (71%, n = 5), married women (57%, n = 4) with >13 years education (86%, n = 6). The three major themes were: personal efficacy beliefs, tai chi intervention active ingredients, and outcome expectations. Social Cognitive Theory underscored stroke survivors' personal efficacy beliefs, behavior, and outcome expectations, while Complex Systems Biology highlighted the active ingredients of the tai chi intervention they experienced. Participation in the 8-week tai chi intervention led to perceived physical, mental, and social benefits post stroke.

Bibliometric Evaluation of Global Tai Chi Research from 1980-2020

While studies on the health benefits of Tai Chi have sprung up over the past four decades, few have engaged in collecting global data, estimating the developing trends, and conducting reviews from the perspective of visualization and bibliometric analysis. This study aimed to provide a summary of the global scientific outputs on Tai Chi research from 1980 to 2020, explore the frontiers, identify cooperation networks, track research trends and highlight emerging hotspots. Relevant publications were downloaded from the Web of Science Core Collection (WoSCC) database between 1980 and 2020. Bibliometric visualization and comparative analysis of authors, cited authors, journals, co-cited journals, institutions, countries, references, and keywords were systematically conducted using CiteSpace software. A total of 1078 publications satisfied the search criteria, and the trend of annual related publications was generally in an upward trend, although with some fluctuations. China (503) and Harvard University (74) were the most prolific country and institution, respectively. Most of the related researches were published in the journals with a focus on sport sciences, alternative medicine, geriatrics gerontology, and rehabilitation. Our results indicated that the current concerns and difficulties of Tai Chi research are "Intervention method", "Targeted therapy", "Applicable population", "Risk factors", and "Research quality". The frontiers and promising domains of Tai Chi exercise in the health science field are preventions and rehabilitations of "Fall risk", "Cardiorespiratory related disease", "Stroke", "Parkinson's disease", and "Depression", which should receive more attention in the future.

Stroke Survivors' Feelings and Perceptions of Their Recovery After a Tai Chi Exercise Intervention: A Qualitative Descriptive Study

BACKGROUND

Most tai chi studies conducted among stroke survivors have focused on physical functioning, whereas inclusion of stroke survivors' feelings and perceptions of participating in tai chi is lacking.

OBJECTIVE

The aim of this study was to identify stroke survivors' feelings and perceptions of participating in a tai chi intervention during their poststroke recovery.

METHODS

This qualitative descriptive study examined stories from community-dwelling stroke survivors, collected as part of a larger randomized clinical trial. To examine these stories, an inductive content analysis approach was used with a priori theoretical codes (and subcodes): (1) Feelings (confidence, enjoy, hopeful, helpful, other) and (2) Perceptions of Impact (physical abilities, mental/cognitive abilities, challenges, other). Lincoln and Guba's criteria were followed to ensure trustworthiness of the study findings.

RESULTS

Participants (n = 17) were on average 71 years old (range, 54-87 years), mainly men (65%), and had the option of writing their own story or having someone write it for them. Stories from these stroke survivors revealed feelings of confidence (n = 4), enjoyment (n = 7), hope (n = 1), and helpfulness (n = 15). Perceptions of the impact of tai chi on their poststroke recovery process identified improved physical abilities (n = 23), better mental/cognitive abilities (n = 12), moving forward (n = 7), and developing friendships (n = 4), with few challenges (n = 1).

CONCLUSIONS

Using storytelling, healthcare providers can discuss the benefits of tai chi and then relate the feelings and perceptions of other stroke survivors' experiences to encourage engagement in regular physical activity to aid in the poststroke recovery process.

Adapting Tai Chi for Upper Limb Rehabilitation Post Stroke: A Feasibility Study

Background: Tai chi (TC) has been reported as being beneficial for improving balance post stroke, yet its utility in upper limb rehabilitation remains unknown. Methods: Twelve chronic stroke survivors with persistent paresis of an upper limb underwent 60 minutes of adapted TC twice a week for eight weeks, with a 4-week follow up. A 10-min TC home program was recommended for the days without sessions. TC level of performance, attendance to the sessions, duration of self-practice at home, and adapted TC movements used were recorded. Results: Eleven participants completed the study. A clinical reasoning algorithm underlying the adaptation of TC was elaborated throughout the trial. Participants with varying profiles including a severely impaired upper limb, poor balance, shoulder pain, and severe spasticity were not only capable of practicing the adapted TC, but attended all 16 sessions and practiced TC at home for a total of 16.51 ± 9.21 h. The degree of self-practice for subgroups with low upper limb function, shoulder pain, or moderate-to-severe spasticity was similar to that of subgroups with greater upper limb function, no shoulder pain, and minimal-to-no spasticity. Conclusion: Adapted TC seems feasible for upper limb rehabilitation post stroke. Although the study was based on a small sample size and requires confirmation, low upper limb function, insufficient balance, spasticity, and shoulder pain do not appear to hinder the practice of TC.
