A prospective study examining balance confidence among individuals with lower limb amputation

PURPOSE: In this study we assessed whether balance confidence scores changed over a 2-year follow up period, and identified predictors of balance confidence and predictors of change in balance confidence among lower limb amputees. METHOD: A prospective follow-up survey of 245 community living adults with unilateral below and above knee lower limb amputation who used their prosthetic limb daily was conducted. Balance confidence, assessed using the 16-item Activity-specific Balance Confidence (ABC) Scale, socio-demographic, health and amputation related variables were collected at baseline and 2 years later. RESULTS: ABC scores were similar at baseline (mean = 67.6; SD = 25.7) and follow up (mean = 68.0; SD = 25.8). Lower balance confidence scores at follow up were predicted by older age, being female, use of a mobility device, poor perceived health, increased symptoms of depression, having to concentrate while walking, and fear of falling (all p < 0.05). Predictors of change in balance confidence included gender and perceived health (all p < 0.05). CONCLUSION: Balance confidence appears to be a persistent problem in the amputee population. Health professionals are encouraged to consider balance confidence as a potentially important variable that may influence function in this clinically unique group of individuals. The identified predictor variables may be useful to clinicians in targeting individuals who require attention to improve balance confidence.     

Physical activity participation amongst individuals with lower limb amputation

Purpose: To examine physical activity participation amongst individuals with lower limb amputation.

Method: Adults with lower limb amputation were convenience-sampled from a major metropolitan hospital outpatient amputee service and completed the International Physical Activity Questionnaire.

Results: Seventy-two individuals (65% male), mean age 53.6 (SD?=?16.8) years, who were 10.8 (SD?=?12.6) years post amputation (60% transtibial) participated in the study. Thirty-eight percent of participants (n?=?27) undertook “high” levels, 26% (n?=?19) undertook “moderate” levels, and 36% (n?=?26) undertook “low” levels of physical activity but cumulative activity levels were low. Participants most commonly undertook domestic-related activities (n?=?53, 74%) and moderate-intensity activities (n?=?54, 75%). Physical activity levels were found to be significantly lower amongst individuals who did not work, individuals with dysvascular amputation and individuals who lived with others. Physical activity levels showed a weak, significant, correlation to age (r_s (70)?=??0.259, p?=?0.028) and time post amputation (r_s (70)?=?0.237, p?=?0.049).

Conclusion: This study provides clinicians with information about physical activity participation amongst individuals with lower limb amputation. The majority of participants in this study (n?=?44, 61%) did not accumulate sufficient “total physical activity” to be classified as “sufficiently active” and 33% (n?=?24) of participants were classified as “sedentary”.

• Implications for Rehabilitation

• Regular physical activity participation is associated with many health benefits.

• This study found the majority of individuals with lower limb amputation (61%) did not undertake sufficient total physical activity to be classified as “sufficiently active”.

• Health professionals working in rehabilitation can play an important role in encouraging individuals to increase physical activity participation.

• The study’s findings may guide health professionals on where to direct their focus to promote increased physical activity participation amongst individuals with lower limb amputation.

     

Measurement properties of the Frenchay Activities Index among individuals with a lower limb amputation

OBJECTIVE: To assess the reliability and validity of the original and a modified version of the Frenchay Activities Index (FAI) among individuals with a lower limb amputation. DESIGN: Two week test-retest design. SETTING: South Western Ontario Amputee Program, London, Ontario, Canada. SUBJECTS: Consecutive sample of 84 individuals, primarily men (78.6%), mean age 56.5 years with a unilateral transtibial (71.4%) or transfemoral amputation related to traumatic (59.5%) or vascular causes. INTERVENTIONS: All subjects completed a questionnaire containing the FAI and other scales, the 2-minute walk and timed up and go tests during a regularly scheduled clinic visit. Fifty-five subjects completed a second FAI which was mailed to them two weeks later. Twenty-nine others completed the second FAI upon return for testing related to another project. MAIN MEASURES: FAI, Activity-specific Balance Confidence Scale, Prosthetic Evaluation Questionnaire-Mobility Scale, 2-minute walk, timed up and go and walking device aid use. RESULTS: Relative reliability for the FAI (intraclass correlation coefficient (ICC) = 0.79) and FAI-18 (ICC = 0.78) was acceptable, however bias between measurements was detected. Hypothesized relationships (p < 0.001) between both FAI versions and the Activity-specific Balance Confidence Scale, Prosthetic Evaluation Questionnaire-Mobility Scale, 2-minute walk and timed up and go test were observed. Significant group differences were observed for amputation cause, mobility device use, age and years as an amputee. Neither version distinguished between amputee level or gender groups. CONCLUSIONS: The original and modified FAI are valid and reliable tools for unilateral amputees. Reliability is adequate to detect group but not individual level differences. Additional FAI-18 items did not substantially improve the ability to detect between-amputation-group differences.     

The influence of falling, fear of falling, and balance confidence on prosthetic mobility and social activity among individuals with a lower extremity amputation

OBJECTIVE: To assess in amputee patients the relationship between having fallen in the past 12 months, fear of falling, and balance confidence on mobility capability, mobility performance, and social activity. DESIGN: Population-based survey and chart review. SETTING: Two university-affiliated outpatient amputee programs in southwestern Ontario. PARTICIPANTS: Community-living individuals (n = 435) with a unilateral lower limb amputation. INTERVENTIONS: Patient chart review and a survey questionnaire. MAIN OUTCOME MEASURES: Self-report assessment of prosthetic capability and performance and social activity participation was assessed with the Prosthetic Evaluation Questionnaire mobility subscale, the Houghton Scale, and the Frenchay Activities Index. RESULTS: Falling experiences in the past 12 months were not significantly associated with any outcomes. Fear of falling was important in univariate relationships in all 3 outcomes, but not when balance confidence was included in multivariable modeling. Balance confidence was statistically significant with each of the outcomes and remained significant with inclusion of the covariates. There was statistical interaction (balance confidence x automatism; balance confidence x medication count) in modeling mobility capability and in modeling mobility performance (balance confidence x pain + balance confidence x amputation level). The final models accounted for 70%, 60%, and 55% of the variation in mobility capability, mobility performance, and social activity, respectively. CONCLUSION: Balance confidence was the only factor associated with mobility capability and performance and social activity in the final adjusted models. Clinicians and researchers should consider this variable in the rehabilitation of amputee patients.     

Health promotion needs of physically disabled individuals with lower limb amputation in Rwanda

Purpose. The objectives of the study were to identify the health-related behaviors among physically disabled individuals with lower limb amputation resident in Rwanda, the factors that influenced these behaviors, and the major issues that should be targeted in health promotion programs for physically disabled individuals with lower limb amputation.

Method. A cross-sectional survey, utilizing a self-administered questionnaire, was carried out among 334 lower limb amputees who volunteered to take part in the study. In addition, a sub-sample of 15 participants was purposively selected for in-depth face-to-face interviews.

Results. Many participants did not engage in physical exercises (64.7%). Others abused alcohol on daily basis (14.4%), smoked 11 - 20 cigarettes daily (13.2%), and used recreational drugs such as marijuana, opium and cocaine (9.6%). There were significant associations between the age group of the participants and participation in exercises (P = 0.001), and consuming alcohol, tobacco and recreational drugs (P = 0.001). In-depth interviews revealed factors influencing the behavior of participants.

Conclusions. Participants were found to be at risk of secondary complications because of poor lifestyle choices. There is a need to develop and promote wellness-enhancing behaviors in order to enhance the health status of physically disabled individuals in Rwanda who have lower limb amputations.

Care planning for children with lower limb amputation

This article explores the pathways of care for children who undergo lower limb amputation, from pre-surgery to rehabilitation. The consequences of surgery are manifold, including that children and their families must cope with life with a disability, effects on mobility, greater demands on metabolic reserve, disfigurement, pain and discomfort. Care can be divided into multidisciplinary pre-operative, post-operative, mid-term rehabilitation, including prosthetic limb casting and fitting, and long-term rehabilitation over many weeks and years. The involvement of the multidisciplinary team as the child progresses is described. It is recommended that care should be co-ordinated by a nominated lead professional. Effective discharge planning is crucial to a successful transition home and continuing rehabilitation.     

Patient rehabilitation following lower limb amputation

Patient rehabilitation following lower limb amputation is essential to provide optimum patient outcomes and to improve the amputee's quality of life. The age of the patient and the stump length or level of amputation emerge as dominant factors affecting the outcome of rehabilitation. A variety of outcome measures are available to assess the patient's rehabilitative potential to maximise functional ability. This article focuses on the factors affecting rehabilitation, outcome measures to assess rehabilitative potential and the nurse's role in providing care for patients following lower limb amputation.     

A prospective study of factors associated with the presence of phantom limb pain six months after major lower limb amputation in patients with peripheral vascular disease.

Because of a lack of evidence to support any treatment for phantom limb pain (PLP), interest has turned to preventing it instead. However, like other areas of PLP research, there is little consensus regarding factors that may be associated with the development of PLP. This study was devised to identify physical and psychological factors associated with PLP development and maintenance. It was a prospective study of 59 patients listed for amputation of a lower limb due to peripheral vascular disease. Each was interviewed before amputation, and the survivors were reinterviewed 6 months afterward. Pain and coping style were the primary outcome measures. The use of high levels of passive coping strategies (P = .001), especially catastrophizing (P = .02) before amputation, were found to be associated with PLP development. Pain was only weakly associated with the presence of PLP 6 months after amputation. The ability to move the phantom (P = .01) and stump pain (P = .01) were postamputation factors associated with PLP. The complexity of the relationship between previous pain and coping style and the development of PLP is discussed alongside aspects of pain memory. Pre-emptive treatment of PLP will need to include psychological as well as physical interventions. PERSPECTIVE: During this study, preamputation passive coping (especially catastrophizing) was found to be associated with the development of PLP. This knowledge will help researchers and clinicians to identify future targets for pre-emption of this condition because once established, PLP is difficult to treat.     

Return to work after lower limb amputation

This study investigated the proportion of patients who returned to work following amputation and the factors that influenced a positive or negative outcome. One hundred patients of working age who had sustained unilateral lower limb amputation at least 1 year previously and who were established prosthesis users participated in the study. A specially designed questionnaire similar to a guided interview was administered by the rehabilitation physician at the patients' routine follow-ups. The questionnaire yielded a unique score dependent on whether return to work (or a different or preferred occupation) had been achieved with good or reduced productivity. All patients were eligible for mobility benefit, including schemes to purchase suitably adapted vehicles if necessary. However, no vocational rehabilitation was available. Sixty-six per cent of patients returned to employment and this was related to mobility, time since amputation and Handicap Scale scores. Age, socket comfort, level and cause of amputation, type of previous work or the presence of other medical problems did not differ between those who did and did not return to work. The Employment Questionnaire showed good correspondence with the London Handicap Scale, indicating some concurrent validity, although future development might include consideration of psychological factors, which could explain more of the reasons for continued unemployment.     

Leisure activities following a lower limb amputation

Purpose. To compare the nature and extent of inter and intralimb coupling during two-handed catching and the effect of manipulating task constraints in children with Developmental Coordination Disorder (DCD) and their typically developing peers (AMC).

Method. Twenty children aged 7 – 10 years, ten with DCD and 10 AMC attempted to catch a ball ten times in condition 1 (C1), ball to the midline; condition 2 (C2), ball to the left shoulder and condition 3 (C3), ball to the right shoulder. Both 3D kinematic data and video data were collected.

Results. Children with DCD caught fewer balls than the AMC children, regardless of age or condition (p ≤ 0.001). Children with DCD demonstrated a higher degree of linkage between limbs in C1 and a lower degree of between limb coupling in C2 and C3 when compared to the AMC (p ≤ 0.05). Differences between the AMC7 – 8 and AMC9 – 10 group were found with respect to interlimb coupling.

Conclusions. The influence of manipulating task constraints and the individual nature of children with DCD must be considered by those involved in rehabilitation. By doing so, children with DCD may search for appropriate motor solutions to many functional movement tasks required for everyday life.     

Return to work after lower limb amputation

Purpose. To review the literature on return to work after lower limb amputation.

Method. A comprehensive review of literature on return to work after lower limb amputation was carried out, searching MEDLINE and PubMED.

Results. Most authors found return-to-work rate to be about 66%. Between 22 and 67% of the subjects retained the same occupation, while the remainder had to change occupation. Post-amputation jobs were generally more complex with a requirement for a higher level of general educational development and were physically less demanding. The return to work depends on: general factors, such as age, gender and educational level; factors related to impairments and disabilities due to amputation (amputation level, multiple amputations, comorbidity, reason for amputation, persistent stump problems, the time from the injury to obtaining a permanent prosthesis, wearing comfort of the prosthesis, walking distance and restrictions in mobility); and factors related to work and policies (salary, higher job involvement, good support from the implementing body and the employer and social support network).

Conclusions. Subjects have problems returning to work after lower limb amputation. Many have to change their work and/or work only part-time. Vocational rehabilitation and counselling should become a part of rehabilitation programme for all subjects who are of working age after lower limb amputation. Better cooperation between professionals, such as rehabilitation team members, implementing bodies, company doctors and the employers, is necessary.

Deep vein thrombosis after lower limb amputation

OBJECTIVE: The purpose of this study is to prospectively document the incidence of deep vein thrombosis (DVT) in the residual limb after a below-knee amputation. DESIGN: Eight of 13 male patients, admitted to the acute rehabilitation floor after a below-knee amputation, were included in the study. Patients already receiving anticoagulants were excluded. An investigator questioned the patient regarding the patient's risk factors for DVT and history of DVT and pulmonary embolus. A coagulation profile was obtained for all patients. A Doppler ultrasound was completed on the residual limb 2 wk after amputation, and if negative, it was repeated 2 wk later. Patients found to have a DVT were treated appropriately. The incidence of DVT was calculated by a point estimate, and a 95% confidence interval was calculated using simple large sample methods. RESULTS: Four of the eight patients had ultrasound evidence of DVT in the thigh. Two of the four patients had signs or symptoms of a DVT. There were a comparable number of risk factors for DVT in both groups. Laboratory values were not statistically significant in predicting the occurrence of DVT, probably because of the limited number of subjects. CONCLUSIONS: The present study supports the assumption that the diagnosis of lower limb DVT is frequently associated with lower limb amputation. However, a larger sample may be necessary to conclude that a routine screening ultrasound of the lower limbs is indicated after a below-knee amputation.     

Expectations of rehabilitation following lower limb amputation: a qualitative study

Abstract

Purpose: To explore the expectations of patients about to undergo prosthetic rehabilitation following a lower limb amputation. Method: Design: Qualitative study using semi structured interviews. Setting: Interviews were conducted at two district general hospitals. Participants: Eight patients who had undergone a major lower limb amputation due to vascular insufficiency were interviewed within two weeks of their amputation. All patients had been referred for prosthetic rehabilitation. Results: Five key themes emerged from the interviews: uncertainty, expectations in relation to the rehabilitation service, personal challenges, the prosthesis and returning to normality. These findings illustrate how participants faced uncertainty both pre- and postoperatively and often looked towards established amputees for the provision of accurate information. Conclusions: As no previous research has specifically explored patients’ expectations following an amputation, this study adds valuable insight into the patient experience. Patient expectations following lower limb amputation appeared to be vague and uninformed which may lead to uncertainty and passivity. It was found that patients did not know what to expect in relation to the rehabilitation process. They expected to return to a normal life following an amputation and this expectation appeared to be an important coping mechanism. Patient information and discussions should form an important part of the rehabilitation process before as well as during prosthetic rehabilitation, to help shape realistic expectations. This will allow patients to take a more active, informed role in the process. Psychoeducation interventions (talking) appears to be as important as “walking” within prosthetic rehabilitation services.

• Implications for Rehabilitation

• Patients’ expectations following lower limb amputation need to be informed by the rehabilitation team and established amputees from an early stage as part of the short- and long-term process of adjustment following amputation.

• Patient expectations of a return to normality appear to be an important part of coping following lower limb amputation, exploration of a new normal, both physically and psychosocially should be addressed as part of the rehabilitation process.

     

Mobility of persons after traumatic lower limb amputation

The objective of this study was to determine the influence of time span since amputation on mobility of persons experiencing traumatic lower limb amputation. A special questionnaire was sent to such persons and responses were analysed statistically. The subjects comprised 223 persons after traumatic lower limb amputation, residents of Slovenia. We discovered that 186 (74.2%) are using their prosthesis for more than 7 hours per day, 109 (52.2%) are able to walk outdoors without crutches, and 129 (57.8%) climb more than 20 stairs per day. In addition, those who are walking without crutches, walking longer distances, still cycling and driving a car are, on average, 5–10 years younger than the others. However, around one-third of persons who were young at the time of amputation face limitations of mobility later in life. A total of 76 (35.3%) are able to walk only up to 500 m out of doors, 38 (18.2%) can walk only with a pair of crutches, 62 (29.7%) need a cane or one crutch, and 37 (16.6%) cannot climb stairs. We conclude that successful fitting and usage of a prosthesis by persons after lower limb amputation promotes independent walking and mobility in everyday life. The level of independence achieved is related to time span since amputation.     

Functional assessment scales and lower limb amputation]

INTRODUCTION: This paper is a review of the literature on assessment tools in lower limb amputees.MATERIAL AND METHODS: The authors have research on Medline(R) data base the different tools with keys words "lower limb amputee or amputation, functional evaluation or outcome assessment tools, activity of daily living", and have completed the research with the references of papers.RESULTS: A comprehensive approach of the consequences of an amputation and of the outcome of prosthetic care should include an evaluation of gait, use of the prosthesis in activities of daily life, acceptability and satisfaction with the device.DISCUSSION: Functional assessment tools that are validated are recent, and most of them were developed in English. They take into account the use and the acceptance of the device, but there is no study using them for an important sample population.CONCLUSION: It is now necessary to translate the recent tools into French, and to confirm their validity and sensitivity to change.
