BACKROUND AND OBJECTIVE: Lower limb strength, particularly of the more paretic side, is known to correlate with comfortable gait speed. This meta-analysis sought to determine the relative value of 6 muscle group strengths as explanators of comfortable gait speed. METHODS: Relevant literature was sought using PubMed, CINAHL Scopus, and a hand search. Information on samples, measurements, and correlations were extracted. Correlational data were subjected to meta-analysis. RESULTS: Results from 6 studies were consolidated. The summary correlations between paretic lower limb strength and comfortable gait speed ranged from 0.45 to 0.61. Data were highly heterogeneous but did not show publication bias. CONCLUSIONS: The correlation between the lower limb strength and comfortable gait speed strength is moderate. However, it does not provide an adequate explanation to guide clinical practice.

BACKROUND AND OBJECTIVE: Grip and knee strength are commonly measured but controversy exists as to whether either is a proxy for the other. The purpose of this meta-analysis was to summarize the correlation between the 2 variables. METHODS: Relevant literature was sought using PubMed, Google, and a hand search. Information on populations, measurements, and correlations were extracted. Correlational data were subjected to meta-analysis. RESULTS: Results from 17 studies were consolidated. The summary correlation between grip and knee extension strength was 0.64 with 95% CI of 0.57 to 0.71. Data were highly heterogeneous but did not show publication bias. CONCLUSION: The correlation between the grip and knee extension strength is good. However, it is not good enough to justify using either as a proxy for the other.

The Relationship

BACKGROUND AND OBJECTIVE: Numerous studies have addressed the relationship between paretic knee extension strength and comfortable walking speed after stroke. However, the correlations reported are highly variable. This review sought to summarize the correlational data using meta-analysis. METHODS: Relevant literature was identified via a search of 3 bibliographic databases. Articles were screened and perused for inclusion. Included articles were examined for information on the sample studied, procedures for measuring strength and gait speed, and correlations reported between the 2 variables. Meta-analysis was used to calculate a summary correlation. RESULTS: Of 299 unique articles, 18 met inclusion criteria. Articles were diverse in regard to samples studied, procedures described, and correlations reported. Meta-analysis using data from all included studies revealed a summary correlation of 0.51. For studies using hand-held or isokinetic dynamometry, the summary correlation was 0.46 and 0.59 respectively. CONCLUSIONS: This study provides a better indication of the correlation between paretic knee extension strength and comfortable gait speed than individual studies. The correlation is high enough to provide support for the routine measurement of paretic knee extension force for individuals who have experienced a stroke.

Background: Sarcopenia is the involuntary loss of muscle mass predicted by aging and is associated with an increased likelihood ofunfavorable results, such as falls, mortality and functional disabilities. Objective: Evaluate balance, gait speed, lower limb strength andfunctionality in sarcopenic and non-sarcopenic elderly. Methods: Cross-sectional study, carried out with 68 subjects aged 60 years orover, residents of the community and possessing an independent gait. The assessment instruments were bioimpedance, balance test,four-meter gait speed test, chair support test and SPPB. Results: The prevalence of sarcopenia in the population of the present studywas 43.3%. In the group of non-sarcopenic subjects, a correlation was found between all the variables evaluated. In the group ofsarcopenic subjects, a correlation was found between lower limbs strength and gait speed. Conclusion: The skeletal muscle mass ofa sarcopenic elderly is related to their lower limb strength and gait speed, but it does not present a significant correlation with balanceand functional performance. Further studies are needed to clarify the behavior of balance, gait speed, lower limb strength and functionalperformance variables when compared to the decrease in muscle mass inherent in aging.

Exercise counteracts aging and pathology symptoms, but there is still scarce research on exercise programs for multimorbid and/or palliative old patients (MPO-Ps). In order to analyze whether the multicomponent physical–cognitive training is beneficial for this population, 17 MPO-Ps (81.59 ± 5.63 years) completed a >26 weeks home-based intervention (20–50 min/session, three sessions/week). Twenty-eight supervised and thirty-two autonomous sessions were gradually distributed along three phases: supervised training (ST), reduced supervision training (RST), and autonomous training (AT). Physical function (gait speed, hand grip and lower-limb strength, balance, and agility), mental status (MMSE), and autonomy in daily living (the Barthel Index) were assessed. Categorical analyses regarding the changes in the walking aids used in the test were added to improve the assessment of strength and agility along the intervention. Despite important study limitations, such as the small sample size and lack of a control group, and despite the MPO-Ps’ very low baseline fitness and initial exercise intolerance, they benefited from the dual-tasking approach, especially in autonomy, lower-limb strength, and balance. Agility improvements were shown only by categorical analyses. As expected, most benefits increased the supervision (ST phase). Gait speed and cognitive status maintained despite the total autonomy in training in the last phase. Further research with larger samples should confirm if multicomponent physical–cognitive exercise, individualized and tailored on daily-basis, together with technical assistance and medical supervision, benefits this MPO-Ps population, and if it can be prescribed to them with security, in spite some of them already being palliative patients.

Objective: This study aimed to investigate the efficacy of high-intensity functional exercise among older adults with dementia. Methods: In this systematic review and meta-analysis of randomized controlled trials, we collected articles published before August 2020 from PubMed, Embase, and the Cochrane Library to evaluate the effect of high-intensity functional exercise on older adults with dementia. Primary outcomes included improvements in balance function and gait performance (speed, cadence, and stride length). The secondary outcomes included lower limb strength, activities of daily living, psychiatric well-being, depression, and cognition. Furthermore, we performed subgroup analysis with two high-intensity functional exercise programs: the Umeå program and Hauer’s program. Results: We identified 15 articles describing six trials including older adults with dementia undergoing high-intensity functional exercise or control activity. The meta-analysis indicated that high-intensity functional exercise, both in Hauer’s program and in the Umeå program, significantly improved balance function (pooled standardized mean difference 0.57, 95% confidence interval 0.31–0.83). Hauer’s program significantly improved gait speed, cadence, stride length, and lower limb strength. Beneficial effects on speed, cadence, and lower limb strength were retained for several months. The Umeå program facilitated activities of daily living and psychiatric well-being, with effects on activities of daily living lasting several months. In the only eligible trial, no effects on cognition were observed. Adverse effects of high-intensity functional exercise were minimal to none. Conclusions: High-intensity functional exercise is generally safe and is recommended for older individuals with mild or moderate dementia to provide benefits in motor performance and daily functioning.

Abstract Background: This meta-analysis aimed to systematically analyse the influencing factors of roller skating on the physical health of children and adolescents and to discuss the intervention effect of roller skating on the physical health of children and adolescents. Methods: Taking "Roller Skating", "Children", "Youth", "roller-skating", "minors", "childhood", and "adolescent" as the subject words, a combination of subject words and free text was used to perform a comprehensive search of 7 electronic databases: China Knowledge Network (CNKI), WanFang and Weipu Periodicals, Web of Science, PubMed, PsycINFO, and SPORTDiscus. We searched for randomized controlled trials of roller skating with respect to promoting the health of children and adolescents. We searched from inception to 31 December 2019, with no language restrictions.Results: Sixteen studies with 1296 patients were included. Pooled analysis showed a favorable effect of Roller Skating in total effective rate.Balance ability (SMD=0.86,95%CI:0.72-1.01;Z=11.94,P < 0.0001),Lower Limb power(SMD=0.52,95%CI:0.33-0.70;Z=5.55,P<0.0001),Speed quality(SMD=0.17,95%CI:0.14-0.20;Z=11.67,P<0.01),Social adaptability(SMD=0.68,95%CI:0.32-1.04;Z=3.67,P<0.01)andEndurace quality(SMD=-0.24,95%CI:-0.38-0.10;Z=3.42,P<0.01)while no significant differences were found in Bodyheigh(SMD=0.13,95%CI:-0.01-0.27;Z=1.79,P>0.01),Flexibility(SMD=0.05,95%CI:-0.09-0.19;Z=0.65,P>0.01),Sensitive quality(SMD=0.64,95%CI:-1.13-2.41;Z=0.71,P>0.01) and Vita capacity(SMD=1.92,95% CI:0.17-3.67;Z=2.15,P>0.01) between the two groups.Conclusion: The current evidence shows that roller skating effectively promotes balance, lower limb strength, speed quality, body endurance and social adaptability in children and adolescents; the improvement in male endurance was lower than that in females in the adolescent stage. However, the improvement in male lower limb strength was greater than that of females, and there was no improvement in the flexibility and agility of males or females in these two periods.
