The effect of Tai Chi and Qigong on health-related quality of life in Parkinson’s disease: a systematic review and meta-analysis of systematic reviews
The overall aim of the treatment in Parkinson’s disease is to optimize functional independence, safety, well-being and thereby health-related quality of life. Tai Chi and Qigong are widely used exercises in Parkinson’s disease, but there is insufficient evidence to support or refute the efficacy of Tai Chi and Qigong, especially on health-related quality of life in patients with Parkinson’s disease. The aim of this study was to conduct a systematic review and a meta-analysis from the systematic reviews that evaluate the effectiveness of Tai Chi and Qigong on health-related quality of life in Parkinson’s disease. A comprehensive literature search was conducted to identify the systematic reviews and meta-analyses by using Cochrane Library, MEDLINE, PubMed, etc., databases up to the end of November 2018. From 1504 articles, seven fulfilled the inclusion criteria and were included in our study. Five of the included systematic reviews were about Tai Chi, and two of them were about both Tai Chi and Qigong. According to our meta-analysis, there was no significant effect of Tai Chi and Qigong on health-related quality of life in patients with Parkinson’s disease, when compared to the control group (standardized mean difference −0.166, 95% confidence interval −0.676 to 0.344; P = 0.523). In conclusion, our systematic review and meta-analysis showed no significant effect of Tai Chi and Qigong statistically on health-related quality of life in patients with Parkinson’s disease, but the small effect size in our study favoured the potential benefit of Tai Chi and Qigong on health-related quality of life in Parkinson’s disease.

Home visits by occupational therapists in acute hospital care: a systematic review
The aim of this review was to determine the utility of home visits by occupational therapists before and after a patient is discharged from an acute care hospital. All relevant published studies were identified by searching the CENTRAL, MEDLINE, EMBASE, Occupational Therapy Systematic Evaluation of Evidence, and WHO International Clinical Trials Registry Platform databases. Randomized controlled trials were included regardless of sex, age, disease, and duration of acute hospitalization. The intervention was predischarge and postdischarge home visits made by an occupational therapist. The primary outcome was the ability to perform activities of daily living at 1 month after the intervention. We identified eight trials (including 1029 patients) that were eligible for inclusion. More than half of the trials had a low risk of bias in random sequence generation, and allocation concealment and the other half had a high risk of bias with regard to blinding of participants. However, the risk of bias in terms of blinding for outcomes assessment was low in more than half the studies. We found that home visits by an occupational therapist in a single study significantly reduced the prevalence of falls but had no significant effects on ability to perform activities of daily living, quality of life, or mood. We could not find adequate evidence to support routine home visits by an occupational therapist in the acute care. In the future, studies with larger sample sizes are needed to validate home visits by occupational therapists in patients after acute care hospitalization.

Trajectories of functional performance and muscle strength recovery differ after total knee and total hip replacement: a performance-based, longitudinal study
Total joint replacement is indicated to alleviate pain and disability associated with hip and knee osteoarthritis. Arthroplasty outcomes are typically reported together, or anecdotal comparisons are made between total knee arthroplasty (TKA) and total hip arthroplasty (THA) recovery. Limited data quantifies differences in recovery trajectories, especially with respect to performance-based outcomes. Seventy-nine people undergoing total knee or THA were followed over 6 months. Functional performance was measured using the stair climb test, timed-up-and-go test, and 6-min walk test. Surgical limb isometric strength was also measured. All outcomes significantly declined 1 month after surgery. Participants in the TKA group showed a greater decline in climbing stairs (P < 0.001), timed-up-and-go (P = 0.01), and 6-min walk distance (P < 0.01). Further, the TKA group lost more strength (P < 0.001) and were weaker than those after THA (P < 0.001). Differences in postoperative outcomes between groups at 3 and 6 months were also observed. The TKA group experiences a greater decline in measured outcomes than the THA group, and muscle strength and functional recovery occurred differently in each group. These findings should be considered in rehabilitation priorities after arthroplasty surgery.

Backward walking observational training improves gait ability in patients with chronic stroke: randomised controlled pilot study
Backward walking has a positive effect on gait ability. Action observational training is an effective treatment method for stroke neurological disorders. This randomised comparator-controlled pilot study aimed to evaluate the feasibility of backward walking observational training on the gait ability of chronic stroke patients. Fourteen chronic stroke participants were randomly allocated to the experimental group (backward walking observation; n = 7) and control group (landscape observation; n = 7). Both groups performed conventional therapy 5 days/week; then the backward walking observation and landscape observation + backward walking training groups performed the observational training 3 days/week for 4 weeks. The primary outcome was measured dynamic gait index, 10-m walking test, and timed up and go test time. Both groups showed significant increases in dynamic gait index, 10-m walking test, and timed up and go test time. The experimental group showed more significant improvements in dynamic gait index (P = 0.04, η2 = 0.336), 10-m walking test (P = 0.04, η2 = 0.306), and timed up and go test time (P = 0.03, η2 = 0.334) than the control group. This pilot study demonstrated that conventional therapy with backward walking observational training improves gait ability. Our findings suggest that observing an action may have a positive effect on chronic stroke patients. Trial Registration Clinical Trials: KCT0003098.

Predictors of functional and motor outcomes following upper limb robot-assisted therapy after stroke
Robot-assisted therapy is an effective treatment for stroke patients and has recently gained popularity. Clinicians and researchers are trying to identify predictors to stratify patients for ensuring better stroke rehabilitation outcomes. However, previous studies have reported controversial results regarding the predictors of upper limb recovery after robot-assisted therapy. Our objective was to determine whether the demographic and clinical characteristics of stroke patients influence the motor and functional outcomes after robot-assisted therapy. We conducted a retrospective analysis of 48 hemiplegic patients who performed upper limb goal-directed tasks using RAPAEL Smart Glove (Neofect, Gyeonggi-do, Republic of Korea). Robot-assisted therapy was administered for 5 days a week over 4 weeks, and each session was for 30 minutes. The parameters of the primary outcomes after robot-assisted therapy were measured with the manual function test and functional independence measure. Correlation analysis showed that age, initial cognitive function, and the initial manual function test and the Modified Ashworth Scale for upper extremity scores were significant factors for independently predicting functional outcomes after robot-assisted therapy. Linear regression analysis revealed that the initial Mini-Mental State Examination (P < 0.001) and initial manual function test (P < 0.001) scores were significant predictors of the primary outcomes. In conclusion, our study suggests that stroke patients presenting with less spasticity, better initial cognitive function, and better initial motor function have a significant correlation with the functional outcomes after robot-assisted therapy.

Algorithm for selection of balance assessment tools in post-stroke patients
The aim of the study was to design an algorithm of selecting the balance assessment tool in patients after stroke, which could be used in a subacute rehabilitation setting. A retrospective study was carried out to analyse results of standardized balance measurements in three groups of stroke patients classified by Functional Ambulation Category (FAC) (FAC 1 or 2, non-functional ambulation; FAC 3 or 4, ambulatory dependent; FAC 5 or 6, ambulatory independent). Balance functions were evaluated in 62 out of 70 patients (88.6%) at admission and discharge with at least with one standardized assessment tool. In 21 patients (30%), two or more assessment tools were used. From admission to discharge significant changes in balance functions in the non-functional ambulatory group were detected by Postural Assessment Scale for Stroke (PASS) (P = 0.003), in the ambulatory dependent group with PASS (P = 0.025) and Berg Balance Scale (BBS) (P = 0.009) and in the ambulatory independent group with the Timed Up and Go Test (P = 0.002) and Functional Gait Assessment (P = 0.029). In a post-stroke rehabilitation most commonly used BBS and PASS are sensitive enough in non-functional ambulatory and ambulatory dependent patients, though they do not reflect the overall balance function. In ambulatory independent patients, significant changes in balance functions can be detected only with the assessment tools that include the measurements of dynamic balance. Based on the findings, the algorithm for the selection of balance assessment tools in post-stroke rehabilitation setting was formulated according to FAC.

Predictors of community reintegration and quality of life after hip fracture among community-dwelling older adults
We aim to explore factors contributing to community reintegration and health-related quality of life (HRQoL) among community-dwelling older adults three months after discharge from inpatient rehabilitation following hip fracture. We performed a prospective cohort study with follow-up. Thirty-three consecutive patients (age 66–89) after surgery for hip fracture repair were recruited from an inpatient rehabilitation unit. Participants were 65+ years old, did not have dementia, and were independent in basic activities of daily living (BADL) at discharge. We examined the contribution of independent variables measuring BADL, cognition, emotional status, pain and social support to the explained variance of two main outcomes: the Reintegration to Normal Living Index (RNLI), measuring self-reported ability to participate in activities and return to life roles; and the Medical Outcomes Study Short-Form Health Survey (SF-12), assessing mental and physical aspects of HRQoL. Stepwise regression analyses revealed that: social support and pain while walking significantly explained 42.1% of variance in the RNLI; social support significantly explained 31.1% of the variance in the SF-12-physical subscale; the number of falls in the previous year, social support and executive functions assessed by the clock drawing test significantly explained 61.9% of the variance in the SF-12 mental subscale. Social support, pain while walking and the number of falls in the previous year can predict community reintegration and HRQoL among older adults three months after discharge from rehabilitation following a surgical hip fracture repair. These factors need to be addressed in rehabilitation programs.

Development of an extensive assessment list for knee osteoarthritis based on the International Classification of Functioning, Disability and Health: a Delphi study
The objective of this study was to develop an extensive assessment list for individuals with knee osteoarthritis based on the International Classification of Functioning, Disability and Health (ICF) osteoarthritis comprehensive Core Set. Ten experienced physical therapists including five lecturers and five clinicians were purposively nominated to form an expert panel. Consensus among the experts was obtained through a four-iteration Delphi technique. A list of ICF categories and their third- and fourth-level categories were selected and matched with outcome measures associated with knee osteoarthritis. The expert panel agreed that 26 out of 38 second-level categories of the comprehensive ICF core set for osteoarthritis were relevant to identify problems related to knee osteoarthritis. The information relevant to the specific categories for knee osteoarthritis was obtained from self-reported, subjective observation and physical examination. The extensive assessment list for knee osteoarthritis based on the comprehensive ICF core set for osteoarthritis was assembled. This assessment tool can be used to expansively identify the multidimensional disabilities of impairment, activity limitation and participation restriction in individuals with knee osteoarthritis.

Factors associated with functional recovery in Japanese patients with convalescent stroke stratified by age: a multicenter observational study
Factors associated with functional recovery after stroke may differ by age demographics because the aging process leads to various regressive changes. The aim of this study was to identify factors related to functional recovery in Japanese patients with convalescent stroke stratified by age. A multicenter retrospective observational study was conducted in 243 patients from six convalescent inpatient rehabilitation wards. Participants were categorized into three groups: 40–64, 65–74, and ≥75 years. Demographic data, laboratory data, physical function, and cognitive function were collected upon admission, and outcome measures were represented using the relative gain of the Functional Independence Measure (FIM effectiveness) during hospitalization. Stepwise multivariate logistic analysis was performed to identify the significant factors for functional recovery in each group. In the 40–64 years group, stroke type [odds ratio (OR), 10.38; 95% confidence interval (CI), 2.22–48.59], spatial neglect (OR, 7.61; 95% CI, 2.07–28.00), and memory disorder (OR, 4.68; 95% CI, 1.08–20.30) were shown to be significant factors. In the 65–74 years group, only memory disorder (OR, 3.42; 95% CI, 1.19–9.81) was significant. In the ≥75 years group, low albumin level (OR, 3.35; 95% CI, 1.05–10.67), severe motor impairment (OR, 5.11; 95% CI, 1.14–22.97), and memory disorder (OR, 4.34; 95% CI, 1.43–13.23) were significantly related to poor functional recovery. In conclusions, the findings showed that there were different trends among the factors related to poststroke functional recovery among the three age groups.
