Non-pharmacological and pharmacological treatments for bone health after stroke: Systematic review with meta-analysis.

BACKGROUND: Hemi-osteoporosis is a common secondary complication of stroke. No systematic reviews of pharmacological and non-pharmacological agents for post-stroke bone health have estimated the magnitude and precision of effect sizes to guide better clinical practice. OBJECTIVES: To examine the benefits and harms of pharmacological and non-pharmacological agents on bone health in post-stroke individuals. METHODS: Eight databases were searched (PubMed, Cochrane library, Scopus, CINAHL Complete, Embase, PEDro, Clinicaltrils.gov and ICTRP) up to June 2023. Any controlled studies that applied physical exercise, supplements, or medications and measured bone-related outcomes in people with stroke were included. PEDro and the GRADE approach were used to examine the methodological quality of included articles and quality of evidence for outcomes. Effect sizes were calculated as standardized mean differences (SMD) and risk ratio (RR). Review Manager 5.4 was used for data synthetization. RESULTS: Twenty-four articles from 21 trials involving 22,500 participants (3,827 in 11 non-pharmacological and 18,673 in 10 pharmacological trials) were included. Eight trials were included in the meta-analysis. The methodological quality of half of the included non-pharmacological studies was either poor or fair, whereas it was good to excellent in 8 of 10 pharmacological studies. Meta-analysis revealed a beneficial effect of exercise on the bone mineral density (BMD) of the paretic hip (SMD: 0.50, 95 % CI: 0.16; 0.85; low-quality evidence). The effects of anti-resorptive medications on the BMD of the paretic hip were mixed and thus inconclusive (low-quality evidence). High-quality evidence showed that the administration of antidepressants increased the risk of fracture (RR: 2.36, 95 % CI 1.64-3.39). CONCLUSION: Exercise under supervision may be beneficial for hip bone health in post-stroke individuals. The effect of anti-resorptive medications on hip BMD is uncertain. The adverse effects of antidepressants on fracture risk among post-stroke individuals warrant further attention. Further high-quality studies are required to better understand this issue.

Which type of mind-body exercise is most effective in improving functional performance and quality of life in patients with Parkinson's disease? A systematic review with network meta-analysis.

BACKGROUND: Several studies have investigated the effect of mind-body exercise (MBE) on functional performance and health-related quality of life (HRQoL) in Parkinson's disease (PD), but it is still very difficult for clinicians to make informed decision on the best mind-body exercise for PD. PURPOSE: We analyzed the relative efficacy of MBE (yoga, Tai-Chi, Pilates, Qigong, and dance) in improving functional performance and HRQoL in patients with PD. METHODS: A systematic review of randomized controlled trials (RCTs) was performed using network meta-analysis (NMA), searching the following databases: Cochrane, Web of Science, and PubMed using specific keywords until December 28, 2021, assessing the effects of MBE on functional performance and HRQoL in patients with PD. RESULTS: This review included 60 RCTs with 2037 participants. A ranking of MBE for modifying various aspects of functional performance and HRQoL was achieved. Pairwise NMA showed Pilates to be the most effective in improving functional mobility (MD: - 3.81; 95% CI (- 1.55, - 6.07) and balance performance (SMD: 2.83; 95% CI (1.87, 3.78). Yoga (MD: - 5.95; 95% CI (- 8.73, - 3.16) and dance (MD: - 5.87; 95% CI (- 8.73, - 3.01) to be the most effective in improving motor function, whereas Qigong (MD: 0.32; 95% CI (0.00, 0.64) was most effective in improving gait speed. Considering HRQoL, dance was found to be the most effective (SMD: - 0.36; 95% CI (- 0.70, -0.01). CONCLUSION: MBE should be considered an effective strategy for improving functional performance and HRQoL in patients with PD. The most effective MBE intervention varied with the functional performance domain. Dance was an effective exercise for improving HRQoL among people with PD. PROSPERO REGISTRATION ID: CRD42022301030.

Baduanjin Qigong Improves Balance, Leg Strength, and Mobility in Individuals With Chronic Stroke: A Randomized Controlled Study.

BACKGROUND: Effective and sustainable exercise training methods for improving balance poststroke are needed. OBJECTIVE: To evaluate the effect of Baduanjin Qigong for improving balance after stroke. METHODS: This was a single-blinded randomized controlled study in which only the assessor was blinded. Fifty-eight people with chronic stroke (mean age: 62.5 ± 11.8 years) were randomly assigned to the experimental (n = 29) or control group (n = 29). The experimental group underwent 8 weeks of supervised Baduanjin training (3 sessions per week). This was followed by home-based practice of the same exercises 3 days a week for another 8 weeks. The control group underwent 2 sessions of supervised conventional fitness training in the first week, followed by home-based exercise practice 3 days a week until the end of week 16. All outcomes were measured at baseline, week 8, and week 16. RESULTS: Significantly greater improvements in the Mini-Balance Evaluation Systems Test (Mini-BESTest), composite equilibrium score (Sensory Organization Test), 5 Times Sit to Stand, and Timed Up and Go test were detected at week 8 in the experimental group than in the control group (P < .017). Further improvement in the Mini-BESTest was observed from week 8 to 16 in the experimental group (P < .001). Other outcomes (Limit of Stability, Fall-Efficacy Scale, Modified Barthel Index, Stroke-Specific Quality of Life) showed no significant results. CONCLUSION: Baduanjin is effective in improving balance, leg strength, and mobility and is a safe and sustainable form of home-based exercise for people with chronic stroke.

Translation and psychometric validation of the traditional Chinese version of patient-reported outcomes measurement information system Pediatric-25 Profile version 2.0 (PROMIS-25) in Chinese Children with Cancer in Hong Kong.

PURPOSE: To translate and cross-cultural validate the PROMIS Pediatric-25 Profile 2.0 (PROMIS-25) into traditional Chinese, and to investigate its psychometric properties in children with cancer in Hong Kong. METHODS: The Functional Assessment of Chronic Illness Therapy translation methodology was adopted in this study. Three panel members evaluated the semantic equivalence and content validity. The psychometric properties were tested with 103 children with cancer (10-18 years). Internal consistency and structural validity were examined by Cronbach's alpha and Rasch analysis. Convergent and divergent validity were assessed by correlating it with traditional Chinese pediatric quality of life inventory™ 4.0 domains (traditional Chinese PedsQL™ 4.0), traditional Chinese Health Questionnaire-9 (C-PHQ-9), and the numeric pain rating scale (NPRS). RESULTS: The semantic equivalence score and content validity index were both 100%. All domains indicated good internal consistency (α = 0.83-0.88) and unidimensionality (variance explained > 55.5% and 1st contrast eigenvalues < 2.0). All items showed good item fit (0.6-1.4). For convergent validity, the traditional Chinese PROMIS-25 domains demonstrated moderate-to-large correlations with traditional Chinese PedsQL™ 4.0 domains (r ≥ ± 0.69), C-PHQ-9 Item-4 and total score (r = 0.75-0.80), except NPRS (r = 0.44). For divergent validity, traditional Chinese PROMIS-25 had low correlations with traditional Chinese PedsQL™ 4.0 domains (r < ± 0.21), C-PHQ-9 item-4 (r = 0.3), and NPRS (r = - 0.12). The traditional Chinese PROMIS-25 fatigue domain was weakly correlated with NPRS (r = 0.39). CONCLUSION: The traditional Chinese PROMIS-25 is semantically and conceptually like the original PROMIS-25 with satisfactory internal consistency, structural validity, and construct validity.

Minimal Clinically Important Difference of Four Commonly Used Balance Assessment Tools in Individuals after Total Knee Arthroplasty: A Prospective Cohort Study.

BACKGROUND: Although balance is commonly assessed during the recovery of total knee arthroplasty (TKA), the minimal clinically important difference (MCID) values of frequently used balance assessment tools have not been established previously in this population. OBJECTIVE: To determine the MCID of four balance tests-ie, the Balance Evaluation Systems Test (BESTest), Mini-BESTest, Brief-BESTest, and the Berg Balance Scale (BBS)-in individuals post-TKA. DESIGN: Prospective cohort. SETTING: Outpatient rehabilitation. PARTICIPANTS: Inclusion criteria: (1) first primary TKA with diagnosed knee osteoarthritis; (2) aged 50-85 years. EXCLUSION CRITERIA: (1) TKA due to rheumatoid arthritis of the knee or traumatic injury; (2) known medical conditions that influence balance ability. One hundred forty-six participants were recruited, and 134 of them with complete data were included in the analysis. INTERVENTIONS: Participants received individualized physiotherapy, consisting of electrotherapy for pain and edema control, mobilization and strengthening exercises, and gait and balance training, once or twice per week between assessments. MAIN OUTCOME MEASUREMENTS: Participants were assessed on the BESTest, Mini-BESTest, Brief-BESTest, BBS, and Functional Gait Assessment (FGA) 2 and 4 weeks after surgery. The FGA was used as the anchor reference measure to calculate the MCID of the other four balance tests. A distribution-based approach was also employed to derive the MCID (ie, standardized effect size of 0.5). RESULTS: The BESTest (area under curve [AUC] = 0.811, 95% confidence interval [CI] 0.739-0.883) had the highest accuracy in detecting clinically important improvements on the FGA (≥4 points), followed by the Mini-BESTest (AUC = 0.782, 95% CI 0.704-0.860), Brief-BESTest (AUC = 0.701, 95% CI 0.618-0.795), and BBS (AUC = 0.586, 95% CI 0.490-0.682). The anchor- and distribution-based MCIDs were 6-8 for the BESTest, 1-2 for the Mini-BESTest, and 2-3 for the Brief-BESTest. CONCLUSIONS: Improvements exceeding MCIDs established above are indicative of significant progress in balance function post-TKA. The BBS is not a recommended tool due to its low AUC value.

Does integrated cognitive and balance (dual-task) training improve balance and reduce falls risk in individuals with cerebellar ataxia?

Frequent falls in people with cerebellar ataxia (CA) is a significant problem Therefore, an intervention that could improve balance and reduce the number of falls is of paramount importance from the patients' perspective. Combining cognitive training with physical training to improve balance is a new approach for reducing the risk of falls in patient populations who are at risk for falls. To determine if adding structured cognitive demands to conventional balance and coordination training we designed the Cognitive-coupled Intensive Balance Training (CIBT) program. We found that the more intensive and focused CIBT intervention reduced dual-task cost, improved balance, and reduced the number of falls in a sample of individuals with CA. We hypothesize that (1) CIBT will improve balance and reduce falls; and (2) CIBT will be a cost-effective treatment option for improving balance and reduce falls. To test these hypotheses, we propose conducting a randomized controlled trial (RCT) with economic evaluation . This paper reports the findings of our study testing the feasibility of the CIBT program, rationale for testing our hypothesis and an overview of our future study design to test the effectiveness and cost-effectiveness of the CIBT program.

The effects of a 6-month Tai Chi Qigong training program on temporomandibular, cervical, and shoulder joint mobility and sleep problems in nasopharyngeal cancer survivors.

INTRODUCTION: Nasopharyngeal cancer (NPC) survivors often sustain head-neck-shoulder impairments from conventional treatments, which could disturb sleep. This novel study aimed to examine the efficacy of Tai Chi (TC) Qigong in optimizing temporomandibular joint (TMJ), cervical, and shoulder joint mobility and reducing sleep problems in NPC survivors. METHODS: Fifty-two NPC survivors participated in the study. The experimental group (n = 25) received 6 months of TC Qigong training (1.5 h/session; 4 sessions/wk including self-practice) while the control group (n = 27) received no training. Cervical side flexion and rotation, shoulder flexion and horizontal flexion range of motion (ROM), mouth opening capacity (interincisor distance), and sleep problems (Medical Outcomes Study Sleep Scale) were assessed at baseline, mid-intervention (3 months), immediately after TC Qigong training, and at 6-month follow-up. RESULTS: Intention-to-treat analysis revealed improvement in cervical side flexion ROM only (P < .008) and unchanged shoulder and TMJ mobility (P > .008) after the TC Qigong training. Deterioration was observed in shoulder flexion ROM and mouth opening capacity in the no-training controls over time (P < .008). Sleep problems also decreased in the TC Qigong group (P < .008), and this effect was most profound during the follow-up period. In addition, improvement in cervical side flexion ROM was associated with a reduction in sleep problems in the experimental group after TC Qigong training (P < .05). CONCLUSIONS: The 6-month TC Qigong intervention improved neck mobility, maintained TMJ and shoulder joint mobility, and reduced sleep problems for NPC survivors. TC Qigong could be an effective nonpharmacological intervention for managing progressive trismus, chronic neck and shoulder hypomobility, and reducing sleep problems among NPC survivors.

Musculoskeletal strength, balance performance, and self-efficacy in elderly ving tsun chinese martial art practitioners: implications for fall prevention.

Objectives. To (1) compare the bone strength, lower limb muscular strength, functional balance performance, and balance self-efficacy between Ving Tsun (VT) martial art practitioners and nonpractitioners and (2) identify the associations between lower limb muscular strength, functional balance performance, and balance self-efficacy among the VT-trained participants. Methods. Thirty-five VT practitioners (mean age ± SD = 62.7 ± 13.3 years) and 49 nonpractitioners (mean age ± SD = 65.9 ± 10.5 years) participated in the study. The bone strength of the distal radius, lower limb muscular strength, functional balance performance, and balance self-efficacy were assessed using an ultrasound bone sonometer, the five times sit-to-stand test (FTSTS), the Berg balance scale (BBS), and the Chinese version of the activities-specific balance confidence scale, respectively. A multivariate analysis of covariance was performed to compare all the outcome variables between the two groups. Results. Elderly VT practitioners had higher radial bone strength on the dominant side (P < 0.05), greater lower limb muscular strength (P = 0.001), better functional balance performance (P = 0.003), and greater balance confidence (P < 0.001) than the nonpractitioners. Additionally, only the FTSTS time revealed a significant association with the BBS score (r = -0.575, P = 0.013). Conclusions. VT may be a suitable health-maintenance exercise for the elderly. Our findings may inspire the development of VT fall-prevention exercises for the community-dwelling healthy elderly.

Impact of massage therapy on motor outcomes in very low-birthweight infants: randomized controlled pilot study.

BACKGROUND: The purpose of the present study was to determine the effects of massage therapy on motor development, weight gain, and hospital discharge in preterm very low-birthweight (VLBW) newborns. METHODS: Twenty-four preterm VLBW newborns (<34 weeks and <1500 g) were enrolled in this randomized controlled pilot study. The intervention group (n = 12) received massage therapy starting at 34 weeks post-conceptional age (15 min daily, 5 days/week for 4 weeks). The infants in the sham treatment group (n = 12) received similar duration of light still touch. Test of Infant Motor Performance (TIMP) score gain, weight gain, and post-conceptional age at discharge were compared between the two groups after intervention using Mann-Whitney U-test. RESULTS: No significant between-group difference in TIMP score gain and weight gain was identified when all subjects were analyzed. In subgroup analysis, among those with below-average pre-treatment TIMP score (<35), the intervention group (n = 6) achieved significantly higher TIMP score gain (P = 0.043) and earlier hospital discharge (P = 0.045) than the sham treatment group (n = 5). These same infants, however, also had significantly shorter duration of total parenteral nutrition than their counterparts in the sham treatment group (P = 0.044). CONCLUSIONS: Massage therapy might be a viable intervention to promote motor outcomes in a subgroup of VLBW newborns with poor motor performance. A larger randomized controlled trial is required to further explore the effects of massage therapy in this high-risk group.
