Physical activity and quality of life of amputees in southern Brazil

Training program intervention to encourage physical activity for health in people with transtibial amputation: A feasibility study

BACKGROUND

People with transtibial amputation (PTTA) would benefit from increased physical activity levels (PAL) but generic programs developed to support increased PAL do not address the barriers which PTTA experience.

OBJECTIVE

To evaluate the effect of a 12-week training program, developed for PTTA, on their PAL.

METHODS

Ten PTTA participated in a 12-week training program, which involved one instructor-led supervised group session per week. The program incorporated balance, flexibility, cardiovascular endurance, strength, and agility, as well as educational elements. Personalized starting level and progression intensity were based on the instructor's assessment in the first training session. The effect of the intervention on PAL (self-report questionnaire and accelerometer), fitness, walking symmetry, and adverse effects was determined by analysis of variance before and after the intervention.

RESULTS

There was a significant increase in self-reported time in moderate-intensity activity and accelerometer-measured step count and time in movement after the program compared with baseline ( p = 0.02). The distance walked in the Six-Minute Walk Test (6MWT) ( p < 0.001), time to perform agility test ( p = 0.01), and lower-limb strength power ( p = 0.01) and endurance ( p = 0.01) were significantly greater after the program, and no adverse effects were identified.

CONCLUSIONS

This study demonstrated an intervention designed specifically for PTTA that can increase PAL.

Comparison of daily step count between the Fitbit Inspire 3 and the activPAL 3 in adults with transtibial amputation

Introduction

Physical activity has significant positive effects on health. Accelerometers can be used to track daily physical activity. The Fitbit Inspire 3 is a commercially available health and fitness tracker, but its validity for tracking steps among individuals with transtibial amputation has not been examined. Therefore, the purpose of this study was to evaluate the concurrent validity of the Fitbit Inspire 3 for assessing free-living daily steps in adults with transtibial amputation.

Methods

Participants (n = 79) completed a general health survey and were provided with a Fitbit Inspire 3 and activPAL 3 accelerometer to wear concurrently for seven days in their home environment. Relationships between the activPAL and Fitbit Inspire 3 were examined using Pearson's Correlation. Paired samples t-tests, mean difference, mean absolute difference, and equivalence testing were used to compared daily step counts between Fitbit Inspire 3 and activPAL 3.

Results

Average step counts were 5,768 ± 3,750 (mean ± SD) and 4,674 ± 3,081 by the Fitbit Inspire 3 and activPAL, respectively. A high correlation (r = 0.93) but significant mean difference was found between the activPAL 3 and Fitbit Inspire 3 (p < 0.001). The mean absolute difference between the devices was 1,347 ± 1,184 steps. On average, the Fitbit Inspire 3 counted 1,094 ± 1,423 more daily steps than the activPAL 3. Equivalency could not be claimed between the devices.

Discussion

The Fitbit Inspire 3 counted more steps compared to the activPAL. Because of the significant mean differences and the large mean absolute difference between the devices, the activPAL 3 and Fitbit Inspire 3 are not interchangeable for estimating physical activity in individuals with transtibial amputation. However, due to the high correlation, the devices will produce similar classification rankings based on step counts.

Survey of physical activity in persons with limb loss during the COVID-19 pandemic in the United States

BACKGROUND

Physical activity has been shown to be fundamental in the prevention of numerous diseases and disorders. Achieving and maintaining physical activity levels can be particularly challenging in those with impairments, such as those experiencing a lower limb amputation. To slow the spread of the virus, COVID-19 lockdown mandates imposed by the US state governments may have inadvertent consequences on physical activity levels of those dependent on specific forms of exercise. Understanding how physical activity levels may have affected persons with limb loss can inform intervention strategies for this vulnerable population.

OBJECTIVES

Examine the effects of the COVID-19 pandemic on physical activity levels in persons with limb loss.

STUDY DESIGN

Mixed-method design.

METHODS

A 20-item logic web-based survey and semistructured interviews were administered to individuals who were 18 years or older, spoke English, and had a history of lower limb loss. Quantitative data were analyzed using SPSS v25, whereas qualitative data were analyzed using constant comparison to formulate themes.

RESULTS

There were a significant effect on the amount of physical activity minutes performed per day, a negative effect on the ability to exercise and participate in societal engagements, and a series of barriers to performing physical activity because of the pandemic.

CONCLUSION

Physical activity was reduced significantly in persons with limb loss during the COVID-19 pandemic. A combination of health concerns, fitness center closures, and social distancing mandates were the primary drivers behind the decrease in activity.

Factors influencing physical activity among individuals with lower limb amputations: a qualitative study

PURPOSE

The purpose of this study was to explore the barriers and facilitators to physical activity from multiple stakeholder perspectives including individuals with LLA and health professionals.

MATERIALS AND METHODS

A qualitative descriptive study situated within an interpretive research paradigm was conducted. Semi-structured interviews were held with individuals with LLA recruited from rehabilitation hospitals in a metropolitan city in Canada. Health professionals with experience in amputation care were recruited from across Canada. Data were analysed using codebook thematic analysis.

RESULTS

Thirty-three individuals with LLA and eighteen health professionals participated. Six themes were generated which represent the perceived barriers and facilitators to physical activity. Themes including Informal and Formal Supports, Availability of and Access to Community Resources, and Fit and Function of the Prosthesis were perceived by many individuals as facilitators, while acting as a barrier for others depending on an individual's circumstances.

CONCLUSIONS

These findings provide us with a basis of understanding from which we can begin addressing barriers to physical activity for individuals with LLA, in support of developing patient-centred interventions and physical activity programs for this population. IMPLICATIONS FOR REHABILITATIONIrrespective of amputation etiology, individuals who have lower limb amputation experience several barriers to engaging in physical activity.Many system-level barriers to physical activity exist for people with lower limb amputation, which include lack of availability and access to community resources and specialised prostheses conducive to physical activity participation.A participatory approach engaging both patients and rehabilitation professionals can address the patient-provider discordance with respect to a patient's motivation and attitude towards physical activity participation by creating a supportive environment conducive to behaviour change.The development of future, patient-centered interventions, and physical activity programs for individuals with lower limb amputation must consider fear of falling as a prominent barrier to physical activity and devise potential strategies to address this barrier, by setting realistic and actionable goals.

Physical Activity Among People With Lower Limb Amputation in Brazil

BACKGROUND

Limb loss affects quality of life, well-being, and autonomy. The World Health Organization has launched a global action plan to reduce physical inactivity and presented recommendations of physical activity for people living with disability. Knowledge of the characteristics of people with lower limb amputation regarding physical activity is important. Thus, the aim of this study was to identify the quantity and type of physical activity done by people with lower limb amputation.

METHODS

The sample (N = 149) included adults aged 53.08 (17.24) years old with lower limb loss. Data collection was performed through the application of a sociodemographic, behavioral, and clinical data sheet and the Brazilian version of the Physical Activity Scale for Individuals with Physical Disabilities.

RESULTS

The total Physical Activity Scale for Individuals with Physical Disabilities score was between 0 and 65.79 metabolic equivalents of task per hour per day, which suggests low practice of physical activities. The most frequently practiced activities (79.9%) were those that involved stationary behavior. Women carried out more domestic activities, and subjects who used lower limb prosthesis and those with traumatic amputation reported higher practice of physical activity.

CONCLUSIONS

People living with lower limb amputation, from different regions of Brazil, have low levels of physical activity and mainly carry out activities of stationary behavior.

Physical activity and quality of life in adults and elderly individuals with lower limb amputation

OBJECTIVE

The aim of this study was to investigate the levels of physical activity (PA) and quality of life (QOL) in adults and elderly individuals with lower limb amputation (LLA).

METHODS

This was a cross-sectional observational study. Participants completed three surveys as follows: a demographic survey, the International Physical Activity Questionnaire, and the World Health Organization Quality of Life. Thirty-six individuals with lower limb amputation were separated into two different groups as follows: Adults-lower limb amputation (n=12), composed of individuals with lower limb amputation who aged from 18-59 years, and Elderly-lower limb amputation (n=24), composed of individuals with lower limb amputation who aged 60 years and above. Statistical differences were determined as p<0.05.

RESULTS

Age and number of individuals with a low level of functional independency were higher in the Elderly-lower limb amputation group (p<0.05). The International Physical Activity Questionnaire scores were reduced in the Elderly-lower limb amputation group (p<0.05). The Pearson's correlation test between low metabolic equivalent task (MET), time since amputation, and family income presented positive significant results in the Elderly-lower limb amputation (p<0.05). Adults-lower limb amputation just presents a positive significant correlation with the low family income (p<0.05).

CONCLUSION

Elderly individuals with lower limb amputation are more susceptible to present negative health outcomes than adults with lower limb amputation.

Semantic equivalence in Brazilian Portuguese translation of the Trinity Amputation and Prosthesis Experience Scales-Revised

BACKGROUND

The Trinity Amputation and Prosthesis Experience Scales-Revised assesses adjustment to amputation and to using a prosthesis and considers psychosocial adjustment, activity restriction, satisfaction with the prosthesis, and other aspects related to health and physical activities, including residual and phantom limb pain.

OBJECTIVES

The aim of this study was to assess the semantic equivalence of the Trinity Amputation and Prosthesis Experience Scales-Revised when translated into Brazilian Portuguese.

STUDY DESIGN

Qualitative study.

METHODS

The process was conducted in five stages: translation of the questionnaire into Brazilian Portuguese; development of a first consensual version in Brazilian Portuguese; appraisal of the translation by an expert committee; back-translation; and semantics assessment of the instrument. For semantic evaluation, the translated and adapted Brazilian Portuguese versions were applied to a convenience sample of 10 individuals.

RESULTS

The translated instrument showed a high degree of comprehension within the target population, as it was observed all questions from Part I and II were score 4 or higher on an Ordinal Scale ranging from 0 to 5.

CONCLUSION

The Brazilian version of Trinity Amputation and Prosthesis Experience Scales-Revised has a satisfactory verbal comprehension and is now ready for assessment of its psychometric properties.

CLINICAL RELEVANCE

The process of semantic evaluation of the Brazilian version of the Trinity Amputation and Prosthesis Experience Scales-Revised makes available to health professionals and researchers who work with people with amputations initial information on cross-cultural adaptation and degree of comprehension of this scale.

Accelerometer assessment of physical activity in individuals with paraplegia who do and do not participate in physical exercise

OBJECTIVE

Our main goal was to measure physical activity (PA) in people with paraplegia. Secondarily, we aimed to establish the relationship between being engaged in physical exercise (PE) and reaching the recommended moderate-to-vigorous physical activity (MVPA) level. We further analyzed the effect of being engaged in PE on the PA levels.

DESIGN

Descriptive cross-sectional.

SETTING

Spanish associations for individuals with spinal cord injury.

PARTICIPANTS

Ninety-six manual wheelchair users with chronic paraplegia.

INTERVENTIONS

Participants wore a wrist accelerometer for one week.

OUTCOME MEASURES

Levels of PA and sedentary behavior. In addition, participants were classified into two groups, exercisers (EG) and non-exercisers (NEG) to analyze the effect of PE enrollment on the variables.

RESULTS

For all participants, a mean (SD) of 5,341.70 (966.4) minutes per week were spent engaged in sedentary behaviors, 2,188.99 (723.9) minutes were spent engaged in light activity, and 206.24 (180.0) minutes were spent engaged in MVPA. There was a significant relationship between PE and reaching the minimum levels of MVPA recommended [x2 (1) = 25.03, P < 0.01]. NEG showed a greater number of minutes per week for sedentary behavior [t (94) = 2.50, P < 0.05, r = 0.25]. The EG spent more than twice as much time doing MVPA than the NEG (263.8 min vs 114.3 min, respectively).

CONCLUSIONS

MVPA levels are low in manual wheelchair users who are not regular exercisers, but most of those who self-reported being regular exercisers reach the minimum levels recommended for health benefits. Sedentary behavior is a concern in this population.

Physical Activity in Adults With an Amputation as Assessed With a Self-Reported Exercise Vital Sign

BACKGROUND

Physical activity (PA) is important for the prevention and treatment of numerous chronic medical conditions. Individuals with a limb amputation face unique challenges for staying physically active. There are few studies evaluating PA of civilians with amputation in the United States.

OBJECTIVE

To evaluate self-reported PA in persons with an amputation in the outpatient setting using a standardized exercise vital sign (EVS) and correlate PA with demographic information, amputation characteristics, and disease burden.

DESIGN

Cross-sectional observational study.

SETTING

Outpatient rehabilitation clinic at a tertiary care institution.

INTERVENTIONS

N/A.

PARTICIPANTS

Two hundred twenty-nine patients with limb amputation.

MAIN OUTCOME MEASUREMENTS

EVS (self-reported weekly participation in moderate to vigorous intensity exercise), disease burden using a modified Charlson Comorbidity Index (CCI), possession of a prosthetic limb, amputation level, time from amputation, body mass index (BMI), gender, race, and age.

RESULTS

A total of 28.8% of patients with limb amputation self-reported exercising at or above 150 min/wk as recommended by the United States Department of Health and Human Services (HHS); 31.8% of patients with transfemoral amputations, 27.8% with transtibial amputations, and 36% with upper extremity amputations reported exercising the recommended amount. Those with a prosthesis exercised 0.91 h/wk more than those without a prosthesis (95% CI 0.01, 1.8, P = .047), and female patients exercised 1.09 h/wk less than male patients (95% confidence interval [CI] 1.69-0.49, P < .001). Increasing age (P = .045), CCI (P = .006), and BMI (P = .005) all had a small but significant correlation with lower EVS. There was no statistically significant correlation between EVS and amputation level, race, or time from amputation.

CONCLUSIONS

Less than one-third of patients with an amputation meet HHS recommendations for aerobic exercise. Male patients, those with a prosthesis, lower CCI, lower BMI, and younger age reported higher PA rates. Assessing EVS can help clinicians to identify patients with amputation that are not sufficiently active and may benefit from PA counseling and prescription.

Quality of life of patients with lower limb amputation with prostheses

Abstract Quality of life is often acknowledged as an important outcome of rehabilitation programs for people with amputation. Despite the importance of the subject, the number of studies focusing on the multiplicity of factors influencing this matter is still limited. These assessments are increasingly needed to demonstrate changes related to intervention over time. In order to evaluate the quality of life of patients with lower limb amputation and wearing prostheses, a study was conducted with 49 patients followed in a rehabilitation hospital in the Midwest region of Brazil. A generic instrument (Medical Outcomes Study 36-Item Short-Form Health Survey) for quality of life assessment and Trinity Amputation and Prosthesis Experience Scale-Revised that is specific for people with amputation were used in addition to a functional assessment measure. The results showed that the time since amputation, male gender and below-knee amputations were predictors of a better perception of quality of life and better adjustment to amputation.

Reported physical activity and quality of life in people with lower limb amputation using two types of prosthetic suspension systems

BACKGROUND

Vacuum-assisted suspension systems provide better suspension than non-vacuum systems, but data are limited on whether they improve physical activity levels and quality of life for people with amputation.

OBJECTIVES

To compare the physical activity and quality of life levels of people with transtibial amputation using PIN/LOCK suspension system or vacuum-assisted suspension systems with those of able-bodied controls and to investigate parameters associated with physical activity levels.

STUDY DESIGN

A cross-sectional observational study.

METHODS

Fifty-one people with amputation and 51 controls participated. The International Physical Activity Questionnaire Short Form and Short Form 36 were used to measure the physical activity and quality of life, respectively.

RESULTS

The total physical activity and Short Form 36 scores were significantly lower in the participants with amputation than the controls. There were no significant differences between the two types of suspension systems in terms of physical activity levels and quality of life. The vacuum-assisted suspension system users reported significantly more bodily pain on the Short Form 36 questionnaire than the controls (p = 0.003). The only parameter that correlated significantly with the total physical activity was the Short Form 36 physical functioning subscale (r = 0.302, p = 0.031).

CONCLUSION

Contrary to our expectations, vacuum-assisted suspension system users compared to PIN/LOCK users did not report greater levels of physical activity or improved quality of life or levels closer to comparable controls.

CLINICAL RELEVANCE

A better understanding of the effects of different prosthetic suspension systems on physical activity and quality of life may help clinicians when prescribing prostheses, as well as setting appropriate prosthetic expectations. This study suggests that vacuum-assisted suspension systems and PIN/LOCK suspension systems provide equal benefit to users with regards to physical activity and quality of life.

Daily step count of British military males with bilateral lower limb amputations: A comparison of in-patient rehabilitation with the consecutive leave period between admissions

BACKGROUND:

Reduced function and health in individuals with lower limb amputation is well documented. Step count measurement could facilitate rehabilitation and help monitor functional health outcomes.

OBJECTIVES:

To determine whether mean daily step count changed between in-patient rehabilitation and consecutive leave periods.

STUDY DESIGN:

Observational study.

METHODS:

Nine individuals with bilateral traumatic amputations attending rehabilitation at the Defence Medical Rehabilitation Centre during a 4-month period were invited to participate in the study (two bilateral transfemoral, two bilateral transfemoral/knee disarticulation, two transfemoral/transtibial, one bilateral transfemoral plus transradial, one bilateral transfemoral plus transhumeral and one transfemoral/transtibial/transradial). Prostheses worn by each participant were fitted with an activity monitor (LAM2^TM; PAL Technologies Ltd, Glasgow). Mean daily step count was analysed for each participant following 2 weeks in-patient rehabilitation and consecutive 2 weeks away from rehabilitation.

RESULTS:

Nine participants completed the study (time since injury: 19 ± 7 months, age: 26 ± 6 years). Mean daily step count significantly decreased from 2258 ± 192 during in-patient rehabilitation to 1387 ± 363 at home ( p < 0.01).

CONCLUSION:

The step count decreased when away from rehabilitation, confirming the hypothesis that the mean daily step count would change between in-patient rehabilitation and consecutive leave period.

CLINICAL RELEVANCE

These data provide an indication of the step count achievable by young, military male personnel with bilateral lower limb amputations and highlights differences between intensive in-patient rehabilitation and consecutive leave periods. It is suggested that further investigation and support of clinical monitoring could facilitate rehabilitation tailored to the individual.

Gender Differences in Psychosocial and Physical Outcomes in Haitian Amputees

OBJECTIVE

The purpose of this study was to investigate the gender differences in psychosocial and physical outcomes in users of lower-extremity prostheses who became amputees after the 2010 earthquake in Haiti.

METHOD

We enrolled 140 unilateral amputees in this cross-sectional study in Port-au-Prince, Haiti. Trained staff administered the assessments by reading the questions aloud to participants. Participants completed the Trinity Amputation and Prosthesis Experience Scales and Locomotor Capabilities Index about 2 yr after the earthquake.

RESULTS

We found no gender differences in psychosocial adjustment and physical outcomes, except for strenuous physical activities and phantom pain, and both genders reported difficulty in social adjustment. After controlling for strenuous physical activities and phantom pain, we found that men showed worse psychosocial adjustment than women.

CONCLUSION

Services for psychosocial adjustment are critical for traumatic amputees and should be incorporated into rehabilitation programs after a disaster. Interventions should consider gender roles in the indigenous culture.

Physical activity barriers and enablers in older Veterans with lower-limb amputation

Little is known about the types of physical activities that older individuals with lower-limb loss perform, correlates of regular physical activity (PA), and barriers and facilitators to PA. We conducted an exploratory study in 158 older Veterans from the Pacific Northwest with a partial foot (35%), below-knee (39%) and above-knee (26%) amputation. Ninety-eight percent of survey respondents were male, on average 65 yr of age and 15 yr postamputation; 36% of amputations were trauma-related. The most commonly reported physical activities were muscle strengthening (42%), yard work and/or gardening (30%), and bicycling (11%). Forty-three percent were classified as physically active based on weekly moderate- and vigorous-intensity PA. History of vigorous preamputation PA was positively associated with being active, while low wealth and watching ≥5 h/d of television/videos were inversely associated. While pain- and resource-related barriers to PA were most frequently reported, only knowledge-related and interest/motivation-related barriers were inversely associated with being active. Family support and financial assistance to join a gym were the most commonly reported factors that would facilitate PA. To increase PA in the older amputee population, interventions should address motivational issues, knowledge gaps, and television watching; reduce financial barriers to exercising; and consider involving family members.

A systematic review of functional and quality of life assessment after major lower extremity amputation

BACKGROUND

When judging the success or failure of major lower extremity (MLE) amputation, the assessment of appropriate functional and quality of life (QOL) outcomes is paramount. The heterogeneity of the scales and tests in the current literature is confusing and makes it difficult to compare results. We provide a primer for outcome assessment after amputation and assess the need for the additional development of novel instruments.

METHODS

MEDLINE, EMBASE, and Google Scholar were searched for all studies using functional and QOL instruments after MLE amputation. Assessment instruments were divided into functional and QOL categories. Within each category, they were subdivided into global and amputation-specific instruments. An overall assessment of instrument quality was obtained.

RESULTS

The initial search revealed 746 potential studies. After a review of abstracts, 102 were selected for full review, and 40 studies were then included in this review. From the studies, 21 different assessment instruments were used 63 times. There were 14 (67%) functional measures and 7 (33%) QOL measures identified. Five (36%) of the functional instruments and 3 (43%) of the QOL measures were specific for MLE amputees. Sixteen instruments were used >1 time, but only 5 instruments were used >3 times. An additional 5 instruments were included that were deemed important by expert opinion. The 26 assessment instruments were rated. Fourteen of the best-rated instruments were then described.

CONCLUSIONS

The heterogeneity of instruments used to measure both functional and QOL outcomes make it difficult to compare MLE amputation outcome studies. Future researchers should seek to use high-quality instruments. Clinical and research societies should endorse the best validated instruments for future use in order to strengthen overall research in the field.

Fatores associados à inatividade física em adolescentes de 10-14 anos de idade, matriculados na rede pública de ensino do município de Salvador, BA

OBJETIVO: Investigar os fatores associados à inatividade física em adolescentes de Salvador, BA. MÉTODOS: Trata-se de um estudo transversal, realizado com 803 jovens de 10 a 14 anos, matriculados na rede pública de ensino da cidade de Salvador, BA. Foram coletados dados referentes ao nível de atividade física (variável dependente), hábitos sedentários, dados demográficos, socioeconômicos, maternos e antropométricos (variáveis independentes). Optou-se pela análise de Poisson multivariada para as análises estatísticas de interesse. RESULTADOS: A prevalência da inatividade física foi de 49,6% (IC 95% 46,14 - 53,06); sendo maior entre as moças (feminino: 59,9%; masculino: 39%, p < 0,001). Em análise multivariada, verificou-se a associação inversa e estatisticamente significante entre inatividade física e condição econômica das famílias classificadas em Classe D/E Piores condições econômicas, tanto para os participantes do sexo masculino (RP = 0,73 IC 95% 0,54 - 0,046) quanto para os do sexo feminino (RP = 0,79 IC95% 0,66 - 0,96) . Em análise complementar por desmembramento dos domínios verificou-se tendência significativamente decrescente da inatividade física, representado pelo deslocamento, com o declínio das condições financeiras dos adolescentes em ambos os sexos (Rapazes - Classes B1/B2/C1 = 20,6,%, C2 = 11,0%, D/E = 6,0%, p=0,001; Moças - Classes B1/B2/C1 = 26,7%, C2 = 12,5%, D/E = 10,8%, p = 0,003). CONCLUÕES A prevalência de inatividade física é alta entre os adolescentes investigados. Jovens de baixo nível econômico são mais ativos em comparação com seus pares de melhor nível econômico. Contudo, a direção da associação entre atividade física e nível econômico é dependente dos domínios da atividade física avaliados.
