Delivering an in-Home Exercise Program via Telerehabilitation: A Pilot Study of Lung Transplant Go (LTGO)

Perceptions of barriers to and facilitators of exercise rehabilitation in adults with lung transplantation: a qualitative study in China

BACKGROUND

Exercise is crucial for pulmonary rehabilitation and improving the prognosis of lung transplantation (LTx) patients. However, many LTx patients in China have low exercise tolerance and compliance, and the reasons behind these challenges have not been fully elucidated. Therefore, this qualitative research aims to identify the barriers to and facilitators of exercise rehabilitation in LTx patients.

METHODS

From January to July 2023, 15 stable LTx patients were recruited and participated in in-depth, semi-structured, face-to-face interviews at Henan Provincial People's Hospital. The interview transcripts were analyzed using the COM-B model and the Theoretical Domains Framework (TDF).

RESULTS

Six general themes including 19 barriers and 14 facilitators for the exercise rehabilitation of LTx patients were identified based on the COM-B model and TDF. The barriers to exercise included physical limitations, insufficient exercise endurance, lack of knowledge, and lack of motivation. The facilitators of exercise included motivation, self-efficacy, perceived significance of exercise rehabilitation, and social support.

CONCLUSION

The study offers detailed insight into the development and implementation of exercise rehabilitation intervention strategies for LTx patients. By combining COM-B model and TDF, the study provides strong evidence that active behavior change strategies are required for LTx patients to promote their participation in exercise rehabilitation. Professional support, pulmonary rehabilitation training, behavior change technology, and digital health tools are essential for strengthening the evidence system for reporting exercise efficacy and effectiveness.

Design of Lung Transplant Go (LTGO): A randomized controlled trial evaluating the efficacy of a telerehabilitation behavioral exercise intervention to improve physical activity, physical function, and blood pressure control after lung transplantation

Background

Lung transplantation is an established treatment option for persons with advanced lung disease. After transplantation, lung function typically returns to near normal levels, however exercise capacity remains low due to chronic deconditioning, limited physical function, and inactive lifestyles which undermine the intended benefits of the highly selective, resource-intensive transplant procedure. Pulmonary rehabilitation is recommended to improve fitness and activity tolerance, however due to multiple barriers, lung transplant recipients either never participate, or fail to complete, pulmonary rehabilitation programs.

Purpose

To describe the design of Lung Transplant Go (LTGO), a trial modified for the remote environment based on recommendations to preserve trial integrity during COVID. The aims are to evaluate a behavioral exercise intervention to improve physical function, physical activity, and blood pressure control in lung transplant recipients conducted safely and effectively using a telerehabilitation (telerehab) platform, and to explore the role of potential mediators and moderators of the relationship between LTGO and outcomes.

Methods

Single-site, 2-group randomized controlled trial with lung transplant recipients randomized 1:1 to either the LTGO intervention (a 2-phased, supervised, telerehab behavioral exercise program), or to enhanced usual care (activity tracking and monthly newsletters). All study activities, including intervention delivery, recruitment, consenting, assessment, and data collection, will be performed remotely.

Conclusion

If efficacious, this fully scalable and replicable telerehab intervention could be efficiently translated to reach large numbers of lung recipients to improve and sustain self-management of exercise habits by overcoming barriers to participation in existing, in-person pulmonary rehabilitation programs.

Lung Transplant Rehabilitation-A Review

BACKGROUND

Both lung transplant recipients and candidates are characterised by reduced training capacity and low average quality of life (QoL). This review investigates the impact of training on exercise ability and QoL in patients before and after lung transplant.

METHODS

Searches were conducted from the beginning to 7 March 2022 using the terms "exercise," "rehabilitation," "lung transplant," "exercise ability," "survival," "quality of life" and "telerehabilitation" in six databases, including Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, CINAHL, Nursing and Allied Health, and Scopus. The inclusion criteria were studies evaluating the effects of an exercise training programme concurrent with lung transplantation as well as patients and candidates (>18 years old) through any lung diseases. The term "lung transplant rehabilitation" was used to refer to all carefully thought-out physical activities with the ultimate or intermediate objective of improving or maintaining physical health.

RESULTS

Out of 1422 articles, 10 clinical- and 3 telerehabilitation studies, candidates (n = 420) and recipients (n = 116) were related to the criteria and included in this review. The main outcome significantly improved in all studies. The 6-min walk distance, maximum exercise capacity, peak oxygen uptake, or endurance for constant load rate cycling improved measuring physical activity [aerobic exercises, breathing training, and aerobic and inspiratory muscle training sessions (IMT)]. Overall scores for dyspnoea improved after exercise training. Furthermore, health-related quality of life (HRQOL) also improved after aerobic exercise training, which was performed unsupervised or accompanied by breathing sessions. Aerobic training alone rather than combined with inspiratory muscle- (IMT) or breathing training enhanced exercise capacity.

CONCLUSION

In conclusion, rehabilitation programmes seem to be beneficial to patients both preceding and following lung transplantation. More studies are required to determine the best training settings in terms of time scale, frequency, and work intensity in terms of improving exercise ability, dyspnoea, and HRQOL.

Exercise Progression Protocol for Lung Transplant GO: A Multicomponent Telerehab Exercise Intervention for Patients After Lung Transplantation

Lung transplantation is one of the fastest growing solid organ transplant procedures in the United States. After transplantation, lung function typically returns to near normal levels; however, reduced physical function and an inactive lifestyle compromise this benefit. To promote rehabilitation goals, lung transplant recipients (LTRs) are advised to participate in pulmonary rehab, but participation is low due to barriers related to scheduling, travel requirements, lack of insurance coverage, and the concern about exposure to infection. Telerehabilitation offers a flexible alternative with the potential to promote self-management of exercise in LTRs. The purpose of this report was to describe the exercise progression protocol for the Lung Transplant GO multicomponent telerehab exercise intervention for patients after lung transplantation. The progression protocol is an evidence-informed exercise protocol designed to improve physical function and physical activity in LTRs safely and effectively in a remote environment. The protocol standardizes the prescription of exercise while permitting adaptation of the program to meet the needs of the individual. Using this model, the decisions about program progression are systematic, transparent, and replicable to other LTRs.

Early Change in Lower Limb Strength and Function in Lung Transplant Patients After Center-Based and Telerehabilitation

PURPOSE

The aim of this study was to examine the change and relationship among quadriceps torque (QT) and physical function in adult lung transplant (LTx) patients undergoing rehabilitation.

METHODS

A prospective study assessed 6-min walk test (6MWT) distance, QT, and Short Physical Performance Battery (SPPB) at the start of pre-habilitation and 10-12 wk post-LTx. Functional outcomes were examined for within-group differences for participants who completed center-based rehabilitation between September 2019 and March 2020 and participants who completed telerehabilitation ("telerehab") between March 2020 and June 2021 during COVID-19. Relationships between QT, SPPB, and 6MWT were examined pre- and post-LTx.

RESULTS

A total of 49 LTx recipients were included (30 men, 61 [56-67] yr, 26 center-based rehab, and 23 telerehab). The 6MWT increased (median 75 m: 95% CI, 35 - 117, P < .0001), and the telerehab group showed an LTx decrease in QT (-9.6 Nm: 95% CI, -29 to -2.3, P = .02) and an increased gait speed (0.21 m/sec: 95% CI, 0.11 - 0.47, P < .0001). Pre-LTx QT showed a moderate correlation to pre-LTx SPPB ( r = 0.41, P = .004) and weak correlations to gait speed and 6MWT ( r ranging from 0.21 to 0.35, P < .05). Post-LTx QT showed moderate correlations to post-LTx SPPB ( r = 0.43, P = .002), gait speed ( r = 0.54, P < .001), five-time sit-to-stand ( r =-0.57, P < .0001), and 6MWT ( r = 0.62, P < .0001).

CONCLUSIONS

Early post-LTx 6MWT and gait speed increased with no improvement in QT or other SPPB components. Correlations between QT and measures of exercise capacity and lower limb function were stronger post-LTx. Serial measurements may further inform functional trajectories and rehabilitation models.

Feasibility and acceptability of a physical activity behavioural modification tele-coaching intervention in lung transplant recipients

BACKGROUND

Despite improvements in pulmonary function following lung transplantation (LTx), physical activity levels remain significantly lower than the general population. To date, there is little research investigating interventions to improve daily physical activity in LTx recipients. This study assessed the feasibility and acceptability of a novel, 12-weeks physical activity tele-coaching (TC) intervention in LTx recipients.

METHODS

Lung transplant recipients within 2 months of hospital discharge were recruited and randomised (1:1) to TC or usual care (UC). TC consists of a pedometer and smartphone app, allowing transmission of activity data to a platform that provides feedback, activity goals, education, and contact with the researcher as required. Recruitment and retention, occurrence of adverse events, intervention acceptability and usage were used to assess feasibility.

RESULTS

Key criteria for progressing to a larger study were met. Of the 15 patients eligible, 14 were recruited and randomised to TC or UC and 12 completed (67% male; mean ± SD age; 58 ± 7 years; COPD n = 4, ILD n = 6, CF n = 1, PH n = 1): TC (n = 7) and UC (n = 5). TC was well accepted by patients, with 86% indicating that they enjoyed taking part. Usage of the pedometer was excellent, with all patients wearing it for over 90% of days and rating the pedometer and telephone contact as the most vital aspects. There were no adverse events related to the intervention. After 12 weeks, only TC displayed improvements in accelerometry steps/day (by 3475 ± 3422; p = .036) and movement intensity (by 153 ± 166 VMU; p = .019), whereas both TC and UC groups exhibited clinically important changes in physical SF-36 scores (by 11 ± 14 and 7 ± 9 points, respectively).

CONCLUSION

TC appears to be a feasible, safe, and well-accepted intervention in LTx.

Musculoskeletal syndrome treated with global postural re-education in double-redo lung transplantation: a case report with an 8-month follow-up

Postoperative pain and persisting fatigue represent critical concerns for patients receiving lung transplantation. The purpose of this study was to illustrate the trajectory of symptoms in a patient who presented with a posttransplant musculoskeletal syndrome after double redo-lung transplantation and attended therapeutic sessions of global postural re-education during the symptomatic phase. A 32-year-old woman with interstitial lung disease underwent double lung transplantation. At 23 months, functional parameters deteriorated, and the patient was placed on the active list for a second double-lung transplantation. Twenty months after re-transplantation, the patient reported continuous thoracic-lumbar musculoskeletal pain exacerbated by moving or performing the standard motor activities. Lower body flexibility improved during the observation period changed from -10 cm to 0 cm at the Chair Sitand- Reach Test. Leg strength improved as well, and the patient was able to perform more repetitions at the Squat Test, improving from 14 to 39. Pain intensity changed from 7 to 4 on a numerical rating scale. We observed that outcomes strictly related to treatment, with lower body flexibility, pain intensity, and physical function improving over time. As a result global postural re-education proved to be effective in this patient.

Feasibility of a Home-Based Exercise Program for Managing Posttransplant Metabolic Syndrome in Lung and Liver Transplant Recipients: Protocol for a Pilot Randomized Controlled Trial

Background

Posttransplant metabolic syndrome (PTMS) is a common contributor to morbidity and mortality among solid organ transplant recipients in the late posttransplant period (≥1 year). Patients diagnosed with PTMS are at a higher risk of cardiovascular disease and frequently experience decreased physical function and health-related quality of life (HRQL). Studies in the early posttransplant period (<1 year) have shown the benefits of facility-based exercise training on physical function and HRQL, but have not evaluated the effects on metabolic risk factors. It remains unclear whether home-based exercise programs are feasible and can be delivered at a sufficient exercise dose to have effects on PTMS. This protocol outlines the methodology of a randomized controlled trial of a partly supervised home-based exercise program in lung transplant (LTx) and orthotopic liver transplant (OLT) recipients.

Objective

This study aims to evaluate the feasibility (ie, recruitment rate, program adherence, attrition, safety, and participant satisfaction) of a 12-week individualized, home-based aerobic and resistance training program in LTx and OLT recipients initiated 12 to 18 months after transplantation, and to assess estimates of intervention efficacy on metabolic risk factors, exercise self-efficacy, and HRQL.

Methods

In total, 20 LTx and 20 OLT recipients with ≥2 cardiometabolic risk factors at 12 to 18 months after transplantation will be randomized to an intervention (home-based exercise training) or control group. The intervention group will receive an individualized exercise prescription comprising aerobic and resistance training, 3 to 5 times a week for 12 weeks. Participants will meet on a weekly basis (via videoconference) with a qualified exercise professional who will supervise exercise progression, provide support, and support exercise self-efficacy. Participants in both study groups will receive a counseling session on healthy eating with a dietitian at the beginning of the intervention. For the primary aim, feasibility will be assessed through recruitment rate, program adherence, satisfaction, attrition, and safety parameters. Secondary outcomes will be measured at baseline and 12 weeks, including assessments of metabolic risk factors (ie, insulin resistance, abdominal obesity, blood pressure, and cholesterol), HRQL, and exercise self-efficacy. Descriptive statistics will be used to summarize program feasibility and effect estimates (means and 95% CIs) for sample size calculations in future trials.

Results

Enrollment started in July 2021. It is estimated that the study period will be 18 months, with data collection to be completed by December 2022.

Conclusions

A partly supervised home-based, individually tailored exercise program that promotes aerobic and resistance training and exercise self-efficacy may be an important intervention for improving the metabolic profile of LTx and OLT recipients with cardiometabolic risk factors. Thus, characterizing the feasibility and effect estimates of home-based exercise constitutes the first step in developing future clinical trials designed to reduce the high morbidity associated with PTMS.

Telerehabilitation for Lung Transplant Candidates and Recipients During the COVID-19 Pandemic: Program Evaluation

BACKGROUND

The COVID-19 pandemic resulted in a rapid shift from center-based rehabilitation to telerehabilitation for chronic respiratory disease and lung transplantation due to infection control precautions. Clinical experience with this delivery model on a large scale has not been described.

OBJECTIVE

The aim of this study is to describe usage and satisfaction of providers and lung transplant (LTx) candidates and recipients and functional outcomes following the broad implementation of telerehabilitation with remote patient monitoring during the first wave of the COVID-19 pandemic.

METHODS

This study was a program evaluation of providers, LTx candidates, and early LTx recipients who used a web-based, remote monitoring app for at least four weeks between March 16 and September 1, 2020, to participate in telerehabilitation. Within-subjects analysis was performed for physical activity, Self-efficacy For Exercise (SEE) scale score, aerobic and resistance exercise volumes, 6-minute walk test results, and Short Physical Performance Battery (SPPB) results.

RESULTS

In total, 78 LTx candidates and 33 recipients were included (57 [51%] males, mean age 58 [SD 12] years, 58 [52%] with interstitial lung disease, 34 [31%] with chronic obstructive pulmonary disease). A total of 50 (64%) LTx candidates and 17 (51%) LTx recipients entered ≥10 prescribed exercise sessions into the app during the study time frame. In addition, 35/42 (83%) candidates agreed the app helped prepare them for surgery and 18/21 (85%) recipients found the app helpful in their self-recovery. The strongest barrier perceived by physiotherapists delivering the telerehabilitation was patient access to home exercise and monitoring equipment. Between the time of app registration and ≥4 weeks on the waiting list, 26 LTx candidates used a treadmill, with sessions increasing in mean duration (from 16 to 22 minutes, P=.002) but not speed (from 1.7 to 1.75 mph, P=.31). Quadriceps weight (pounds) for leg extension did not change (median 3.5, IQR 2.4-5 versus median 4.3, IQR 3-5; P=.08; n=37). On the Rapid Assessment of Physical Activity questionnaire (RAPA), 57% of LTx candidates scored as active, which improved to 87% (P=.02; n=23). There was a decrease in pretransplant 6-minute walk distance (6MWD) from 346 (SD 84) meters to 307 (SD 85) meters (P=.002; n=45) and no change in the SPPB result (12 [IQR 9.5-12] versus 12 [IQR 10-12]; P=.90; n=42). A total of 9 LTx recipients used a treadmill that increased in speed (from 1.9 to 2.7 mph; P=.003) between hospital discharge and three months posttransplant. Quadriceps weight increased (3 [IQR 0-3] pounds versus 5 [IQR 3.8-6.5] pounds; P<.001; n=15). At three months posttransplant, 76% of LTx recipients scored as active (n=17), with a high total SEE score of 74 (SD 11; n=12). In addition, three months posttransplant, 6MWD was 62% (SD 18%) predicted (n=8).

CONCLUSIONS

We were able to provide telerehabilitation despite challenges around exercise equipment. This early experience will inform the development of a robust and equitable telerehabilitation model beyond the COVID-19 pandemic.

Considerations for assessing physical function and physical activity in clinical trials during the COVID-19 pandemic

The coronavirus disease-2019 (COVID-19) pandemic has changed the conduct of clinical trials. For studies with physical function and physical activity outcomes that require in-person participation, thoughtful approaches in transitioning to the remote research environment are critical. Here, we share our experiences in transitioning from in-person to remote assessments of physical function and activity during the pandemic and highlight key considerations for success. Details on the development of the remote assessment protocol, integration of a two-way video platform, and implementation of remote assessments are addressed. In particular, procedural challenges and considerations in transitioning and conducting remote assessments will be discussed in terms of efforts to maintain participant safety, maximize study efficiency, and sustain trial integrity. Plans for triangulation and analysis are also discussed. Although the role of telehealth platforms and research activities in remote settings are still growing, our experiences suggest that adopting remote assessment strategies are useful and convenient in assessing study outcomes during, and possibly even beyond, the current pandemic.

Video Telehealth Occupational Therapy Services for Older Veterans: National Survey Study

BACKGROUND

Occupational therapy (OT) is a vital service that supports older adults' ability to age in place. Given the barriers to accessing care, video telehealth is a means of providing OT. Even within Veterans Health Administration (VHA), a pioneer in telehealth, video telehealth by OT practitioners to serve older adults is not well understood.

OBJECTIVE

This study examines VHA OT practice using video telehealth with older veterans using an implementation framework.

METHODS

A web-based national survey of VHA OT practitioners conducted between September and October 2019 contained a mix of mostly closed questions with some open-text options. The questions were developed using the Promoting Action on Research Implementation in Health Services model with input from subject matter experts. The questions gathered the extent to which VHA OT practitioners use video telehealth with older veterans; are comfortable with video telehealth to deliver specific OT services; and, for those using video telehealth with older veterans, the barriers, facilitators of change, and perceived benefits of video telehealth.

RESULTS

Of approximately 1455 eligible VHA OT practitioners, 305 participated (21.0% response rate). Most were female (196/259, 75.7%) occupational therapists (281/305, 92.1%) with a master's degree (147/259, 56.8%) and 10 years or fewer (165/305, 54.1%) of VHA OT practice. Less than half (125/305, 41.0%) had used video telehealth with older veterans, and users and nonusers of video telehealth were demographically similar. When asked to rate perceived comfort with video telehealth to deliver OT services, participants using video telehealth expressed greater comfort than nonusers, which was significant for 9 of the 13 interventions: activities of daily living (P<.001), instrumental activities of daily living (P=.004), home safety (P<.001), home exercise or therapeutic exercise (P<.001), veteran or caregiver education (P<.001), durable medical equipment (P<.001), assistive technology (P<.001), education and work (P=.04), and wheelchair clinic or seating and positioning (P<.001). More than half (74/125, 59.2%) of those using video telehealth reported at least one barrier, with the most frequently endorsed being Inadequate space, physical locations and related equipment. Most (92/125, 73.6%) respondents using video telehealth reported at least one facilitator, with the most frequently endorsed facilitators reflecting respondent attitudes, including the belief that video telehealth would improve veteran access to care (77/92, 84%) and willingness to try innovative approaches (76/92, 83%).

CONCLUSIONS

Most VHA OT survey respondents had not used video telehealth with older veterans. Users and nonusers were demographically similar. Differences in the percentages of respondents feeling comfortable with video telehealth for specific OT interventions suggest that some OT services may be more amenable to video telehealth. This, coupled with the primacy of respondent beliefs versus organizational factors as facilitators, underscores the need to gather clinicians' attitudes to understand how they are driving the implementation of video telehealth.

Telerehabilitation Intervention in Patients with COVID-19 after Hospital Discharge to Improve Functional Capacity and Quality of Life. Study Protocol for a Multicenter Randomized Clinical Trial

COVID-19 can cause important sequels in the respiratory system and frequently presents loss of strength, dyspnea, polyneuropathies and multi-organic affectation. Physiotherapy interventions acquire a fundamental role in the recovery of the functions and the quality of life. Regarding the recovery phases after hospital discharge, the current evidence available is very preliminary. Telerehabilitation is presented as a promising complementary treatment method to standard physiotherapy. The main objective of this research is to evaluate the effectiveness of a personalized telerehabilitation intervention after discharge from hospital for the improvement of functional capacity and quality of life compared to a program of health education and/or care in a rehabilitation center. As secondary objectives, to identify the satisfaction and perception of patients with the telerehabilitation intervention and the presence of barriers to its implementation, as well as to evaluate the cost-effectiveness from the perspective of the health system. This study protocol will be carried out through a single blind multicenter randomized clinical trial in the south of Spain. We hypothesize that the implementation of a telerehabilitation program presents results not inferior to those obtained with the current standard intervention. If the hypothesis is confirmed, it would be an opportunity to define new policies and interventions to address this disease and its consequences. Trial registration NCT04742946.

Exercise training for lung transplant candidates and recipients: a systematic review

Exercise intolerance and impaired quality of life (QoL) are characteristic of lung transplant candidates and recipients. This review investigated the effects of exercise training on exercise capacity, QoL and clinical outcomes in pre- and post-operative lung transplant patients.A systematic literature search of PubMed, Nursing and Allied Health, Cochrane (CENTRAL), Scopus and CINAHL databases was conducted from inception until February, 2020. The inclusion criteria were assessment of the impact of exercise training before or after lung transplantation on exercise capacity, QoL or clinical outcomes.21 studies met the inclusion criteria, comprising 1488 lung transplant candidates and 1108 recipients. Studies consisted of five RCTs, two quasi-experimental and 14 single-arm cohort or pilot studies. Exercise training improved or at least maintained exercise capacity and QoL before and after lung transplantation. The impact on clinical outcomes was less clear but suggested a survival benefit. The quality of evidence ranged from fair to excellent.Exercise training appears to be beneficial for patients before and after lung transplantation; however, the evidence for direct causation is limited by the lack of controlled trials. Well-designed RCTs are needed, as well as further research into the effect of exercise training on important post-transplant clinical outcomes, such as time to discharge, rejection, infection, survival and re-hospitalisation.

Telerehabilitation for Knee Osteoarthritis in Brazil: A Feasibility Study

BACKGROUND

The effectiveness of telerehabilitation for a patient with knee osteoarthritis may depend upon the person's adherence to intervention. Thus, the aim of this study was to investigate whether people with knee osteoarthritis would adhere to exercise-therapy facilitated via multiple media in Brazil, a newly industrialized country.

METHOD

This is a feasibility study, pre-post intervention. Middle aged (40-50 years) and elderly (≥70 years) people with knee osteoarthritis received in-person exercise-therapy instructions on the first day, along with a booklet and DVD (videos) to take home. Participants also received six motivational phone calls throughout the 12-week treatment. Satisfaction and adherence were assessed one week after intervention with the Exercise Adherence Rating Scale (EARS), sections B and C. Preference on the method used to adhere to exercises was recorded.

CONCLUSION

Telerehabilitation was well accepted by middle-aged and elderly Brazilians with knee osteoarthritis. The preferred media to enhance adherence, was a booklet with descriptions of the exercises, especially for the elderly cohort.

In-Home Video Telehealth for Dementia Management: Implications for Rehabilitation

PURPOSE OF REVIEW

The progressive nature of dementia requires ongoing care delivered by multidisciplinary teams, including rehabilitation professionals, that is individualized to patient and caregiver needs at various points on the disease trajectory. Video telehealth is a rapidly expanding model of care with the potential to expand dementia best practices by increasing the reach of dementia providers to flexible locations, including patients' homes. We review recent evidence for in-home video telehealth for patients with dementia and their caregivers with emphasis on implications for rehabilitation professionals.

RECENT FINDINGS

Eleven studies were identified that involved video visits into the home targeting patients with dementia and/or their family caregivers. The majority describe protocolized interventions targeting caregivers in a group format over a finite, pre-determined period. For most, the discipline of the interventionist was unclear, though two studies included rehabilitation interventions. While descriptions of utilized technology were often lacking, many reported that devices were issued to participants when needed, and that technical support was provided by study teams. Positive caregiver outcomes were noted but evidence for patient-level outcomes and cost data are mostly lacking.

SUMMARY

More research is needed to demonstrate implementation of dementia best care practices through in-home video telehealth. Though interventions delivered using in-home video telehealth appear to be effective at addressing caregivers' psychosocial concerns, the impact on patients and the implications for rehabilitation remain unclear. Larger, more systematic inquiries comparing in-home video telehealth to traditional visit formats are needed to better define best practices.

Impairments in Postural Control and Retest Reliability of Dynamic Posturographic Measures After Lung Transplantation

OBJECTIVES

The aims of the study were to classify impairments in postural control using computerized posturography in lung transplant recipients undergoing subacute rehabilitation and to examine the retest reliability of these measures.

METHODS

In a prospective repeated-measures study, 50 lung transplant recipients underwent clinical and quantitative posturographic testing (SMART EquiTest), which included the sensory organization test, motor control test, and limits of stability test. Testing was repeated after 1 to 2 days and upon completion of rehabilitation, 2 mos later. Main outcome measures were the following: sensory organization test-composite score, motor control test-latency and amplitude scaling, limits of stability test-movement velocity, and endpoint excursion/maximum excursion.

RESULTS

At the beginning of rehabilitation, the mean sensory organization test-composite score and limits of stability test, but not the motor control test scores, were below normative reference values and and did not return to normal after rehabilitation. Intraclass correlation coefficients(2,1) yielded excellent relative reliability for all posturographic tests. The smallest detectable differences observed for the sensory organization test and limits of stability test exceeded the mean changes observed upon completion of rehabilitation.

CONCLUSIONS

Impairments in sensory and anticipatory postural control were insufficiently restored after subacute lung transplantation rehabilitation. The little sensitivity of the sensory organization test-composite score or limits of stability test scores to detect a minimal change in performance due to rehabilitation limits the clinical applicability of these tests as objective outcome measures in lung transplantation rehabilitation.
