Physical deficits among people living with HIV: a review of the literature and implications for rehabilitation

Gait Speed, Mobility, Balance, and Dual-Tasking Deficits Among People Living With HIV Globally: A Systematic Review and Meta-Analysis

ABSTRACT

People living with HIV (PLWH) may experience premature physical deficits, including walking, mobility, and balance problems. The purpose was to measure deficits in walking, mobility, balance, and dual tasking in PLWH. The secondary objective was to make recommendations regarding the use of rehabilitation outcome measures. CINAHL, PubMed, and SPORTDiscus databases were searched. Two independent reviewers screened titles/abstracts and full-text articles, extracted data, and performed a quality assessment. Fifty-six articles with 14,053 PLWH and 8,454 uninfected controls were included. A meta-analysis revealed significantly worse performance among PLWH on the five times sit to stand mobility test versus controls (Cohen d = 0.68, 95% confidence interval [CI 0.08-1.29], p = .03). Meta-analyses revealed no differences between PLWH and controls for usual gait speed (Cohen d = -0.47, 95% CI [-1.10 to 0.15], p = .14) and fast gait speed (Cohen d = -0.39, 95% CI [-0.87 to 0.08], p = .10). Ten of 12 studies comparing PLWH with controls found differences in balance outcomes. PLWH have significantly worse mobility than uninfected controls.

Frailty in people living with HIV: an update

PURPOSE OF REVIEW

The HIV population is ageing with rising rates of frailty though strategies of how best to manage it remain ill-defined. It also remains unclear what the prevalence of frailty is within this cohort, how best to diagnose it and what factors are associated.

RECENT FINDINGS

The prevalence of frailty remains unclear because of heterogenous results. Routine screening in those 50+ is recommended and whilst the Fried Frailty Phenotype is currently preferred the Clinical Frailty Scale could be considered. No biomarkers are currently recommended. Looking at associated factors, HIV neurocognitive impairment and long-term alcohol usage has been shown to be associated with developing frailty whilst those who are frail have been shown to be less active and more likely to fall. NAFLD with fibrosis has been shown to be an indicator of metabolic age and the Pooled Cohort Equations has been shown to be more effective in diagnosing cardiovascular risk in frail people living with HIV.

SUMMARY

Whilst the prevalence of frailty differs between countries, with the addition of prefrailty, this represents a large proportion of people living with HIV. Services must ensure strategies are in place to support those living with HIV and frailty. Further longitudinal studies are required.

Mobility Deviations in Adults With Human Immunodeficiency Virus: A Cross-Sectional Assessment Using Gait Analysis, Functional Performance, and Self-Report

Background

Little is known about how human immunodeficiency virus (HIV) affects walking biomechanics, or about associations between HIV-related gait deviations, functional performance, and self-reported outcomes. This paper reports on (1) gait biomechanics and variability in people with HIV (PWH) and (2) associations with clinical tests, self-reported function, and falls.

Methods

A cross-sectional study tested consecutively sampled PWH (n = 50) and HIV-seronegative participants ([SNP] n = 50). Participants underwent 3-dimensional gait analysis, performed clinical tests (short walk and single leg stance tests with and without dual tasking, chair-rise tests, and a physical performance battery), and completed questionnaires about function and falls. Between-group comparisons were done using analysis of covariance. Linear correlations between gait variability, clinical tests, and patient-reported outcomes were established.

Results

People with HIV and SNP had comparable median ages (PWH = 36.6, interquartile range [IQR] = 32.0–45.6]; SNP = 31.1, IQR = 23.2–45.1). Compared with SNP, PWH walked slower (adjusted mean difference [MD] = −0.2 meters per second [m/s], 95% confidence interval [CI] = −0.3 to −0.1) with greater variability (adjusted MD = 14.7 variability score points, 95% CI = 9.9–19.5). Moreover, PWH were slower in five-times sit-to-stand (5STS) performance (adjusted MD = 1.9 seconds, 95% CI = 1.00–2.9). Significant deviations in hip kinematics (increased flexion; adjusted MDs = 2.4°–2.8°, P = .012–.016) and knee kinematics (reduced flexion; adjusted MDs = 2.3°–3.7°, P = .007–.027) were found in PWH during dual-task (DT) walking. The PWH’s 5STS moderately correlated with larger gait variability (usual pace r = −0.5; dual task r = −0.6), poorer self-reported mobility (r = 0.4) and self-care function (r = 0.5), and fear of falling (P = .003).

Conclusions

People with HIV presented with biomechanical deviations suggestive of a slowed and variable gait, especially under cognitive challenges. Five-times STS may be useful to screen for gait deviations in PWH.

Strengths and Challenges of Implementing Physiotherapy in an HIV Community-Based Care Setting: A Qualitative Study of Perspectives of People Living with HIV and Healthcare Providers

The needs of people living with HIV (PLWH) who have access to antiretroviral therapy have shifted from hospital to community care; however, little is known about physiotherapy within HIV community-based care. Our aim was to understand strengths and challenges of implementing physiotherapy within an interprofessional HIV day health program in Toronto, Ontario, Canada. We conducted a qualitative descriptive study using semi-structured interviews. Data were analyzed using inductive content analysis. Fifteen PLWH and 5 healthcare providers participated. Strengths included improved access to physiotherapy and fulfilling an unmet need for rehabilitation; a tailored approach to physiotherapy; co-location improved communication, coordination, and engagement in care; and improved health outcomes for PLWH (i.e. function, psychosocial outcomes, and quality of life). Challenges related to managing expectations; variable attendance at visits; and managing complex and diverse needs of PLWH. Results may be transferable to other community-based care settings that provide care for PLWH and complex multi-morbidity.
