Amputation rehabilitation and prosthetic restoration. From surgery to community reintegration

PURPOSE: The purpose of this review is to summarize the literature related to the advances that have taken place in the management and rehabilitation care of limb amputation. RESULTS: Prostheses for the lower and upper limb amputee have changed greatly over the past several years, with advances in components, socket fabrication and fitting techniques, suspension systems and sources of power and electronic controls. Higher levels of limb amputation can now be fitted with functional prostheses, which allow more patients to achieve independent life styles. This is of particular importance for the multi-limb amputee. The rehabilitation of more traditional lower limb levels of amputation have also greatly benefited from the technological advances including energy storing feet, electronic control hydraulic knees, ankle rotators and shock absorbers to mention a few. For the upper limb amputee, myoelectric and proportional controlled terminal devices and elbow joints are now used routinely in some rehabilitation facilities. Experimental prosthetic fitting techniques and devices such as the use of osseo-implantation for suspension of the prosthesis, tension control hands or electromagnetic fluids for knee movement control will also be briefly discussed in this paper. CONCLUSION: It is possible to conclude from this review that many advances have occurred that have greatly impacted the functional outcomes of patients with limb amputation.

Evaluation of prosthetic usage in upper limb amputees

Purpose: Upper limb amputations cause severe functional disability and lower the patient's self body image, with severe psychological implications. Many parameters are involved in the successful rehabilitation of upper limb amputations. The aim of this study was to investigate whether there are any parameters that might predict the successful prosthetic rehabilitation of upper limb amputees.

Method: The records of 45 patients who had undergone an upper limb amputation were traced. The patients were evaluated according to four parameters: (1) Modified upper extremities amputees' questionnaire; (2) Pain level according to Visual Analog Scale (VAS), range from 1 (lowest) up to 10 (highest); (3) Pain type - phantom or pain in the stump; (4) Functional assessment of prosthetic usage.

Results: Thirty (71.43%) of the patients reported difficulties with prosthesis usage. Twenty-three patients (54.76%) were satisfied with their prosthesis - 19 had cosmetic prosthesis and four had body-powered prosthesis.

Conclusion: No significant affect of the amputation level except for trans-wrist amputation with 100% prosthesis use. No significant difference was found between prosthesis type and the correlation to stump problems.

The above-elbow amputees, with dominant hand amputation, who used functional prosthesis (body-powered), achieved the best functional outcome and result.     

The relationship between catastrophizing and disability in amputees experiencing phantom pain

Purpose: In recent years, researchers have noted that catastrophizing predicts both self-reported and objective measures of disability in a variety of chronic pain conditions. The present study sought to examine this in a working-age amputee population experiencing phantom pain.

Method: Participants completed a postal questionnaire incorporating measures of pain, disability and coping. A response rate of 62% resulted in 315 completed data sets being incorporated into the study.

Results: Utilizing the three subscales of the Sickness Impact Profile, catastrophizing uniquely predicted 11% of the variance in overall level of disability, 6% in physical disability and 13% in psychosocial disability after accounting for demographic, amputation and pain-related variables.

Conclusion: The findings suggest that catastrophizing is a significant predictor of self-reported disability in an amputee population. This population have lifetime rehabilitation needs in that prostheses have to be remade on a regular basis. The service provided tends to focus on physical rehabilitation with the goal of providing amputees with limbs that most closely resemble the appearance and function of the intact limb. This study provides tentative support for development of an intervention that specifically targets catastrophizing.     

Mirror treatment of lower limb phantom pain: A case study

Purpose: Phantom limb pain (PLP) can be an enduring and distressing experience for people with amputations. Previous research has shown that 'mirror treatment' can reduce PLP for some people who have an upper limb amputation, and that it can increase a sense of motor control over the phantom in people with lower limb amputations who are not reporting PLP. There has been no previous report of therapeutic 'mirror treatment' for lower-limb phantom pain.

Method: We present the first case study of the use of 'mirror treatment' in a person with a lower limb amputation who was reporting PLP at the time of treatment.

Results: During the intervention there was a significant reduction in his PLP, an increase in sense of motor control over the phantom and a change in aspects of the phantom limb that was experienced.

Conclusion: This case study, conducted in a conventional clinical setting, supports the potential of 'mirror treatment' for PLP in people with a lower limb amputation.     

A comparison of upper limb amputees and patients with upper limb injuries using the Disability of the Arm, Shoulder and Hand (DASH)

Purpose: To use the Disability of the Arm Shoulder and Hand (DASH) scale to measure the disability of patients with upper limb amputation(s) and to compare these to other upper limb injuries.

Method: All 274 patients over the age of 18 years presenting to Prince Henry Hospital in Sydney over a 4-year time frame were given the DASH assessment tool and asked to complete it under supervision of the Occupational Therapist.

Results: Patients with brachial plexus injuries, Complex Regional Pain Syndrome and bilateral upper limb amputations demonstrated significantly higher levels of disability to patients with unilateral upper limb amputations. Partial hand amputees reported a higher level of disability than major unilateral upper limb amputees. For the 48 patients who completed pre- and post-treatment assessments, there was a significant improvement in their health status.

Conclusions: Further research is required to understand the factors that affect a patient's perceptions of their disability. Perhaps the definitive nature of an amputation and the immediate involvement of highly skilled health professionals serve to assist patients to accept their injury and therefore minimizes the level of disability.     

Gender differences in amputation outcome

Purpose. To assess the influence of gender on the success of limb-fitting after amputation.

Methods. One-hundred and five successive in-patients admitted to an amputee rehabilitation ward were followed to assess the success of limb-fitting at discharge. The influence of demographic, clinical and social factors on the success of lower limb-fitting was assessed using linear regression analysis and group comparisons.

Results. There were 35 (33%) women in a cohort of 105 successive admissions. Men and women were comparable in terms of age, length of stay, medical comorbidity and level of amputation. Women were less likely to be successfully fitted with a prosthetic limb at discharge than men (42.9% vs 68.6%, p = 0.011), and more women lived alone (57.1% vs 38.6%, p = 0.021). Linear regression revealed that gender was an independent significant factor in the success of limb-fitting; age, level and cause of amputation, co-morbidity and length of stay were not significant factors.

Conclusions. Women were less likely to be successfully fitted with a lower limb prosthesis after amputation.     

Reliability, validity and factor structure of the upper limb subscale of the Motor Assessment Scale (UL-MAS) in adults following stroke

Purpose: The upper limb items of the Motor Assessment Scale (MAS) have been shown to be a sensitive, valid and reliable measure of upper limb function for adults following stroke, however the validity and reliability of summing these items into an independent subscale has not yet been evaluated. The stability, internal consistency and construct validity of the upper limb MAS subscale (UL-MAS) was assessed in this study.

Method: Twenty-seven inpatients following stroke (mean age = 67 years, range = 40 - 80) were sampled from an acute, inpatient rehabilitation setting. Patients were evaluated with 'Upper Arm Function', 'Hand Movements', and 'Advanced Hand Activities' items of the MAS by masked physiotherapists who had received standardized training in administration of the MAS.

Results: All items were explained by one factor on confirmatory factor analysis and correlated significantly with one another and with the composite (summed total) score. Internal consistency analysis produced a Cronbach's alpha of 0.83 which did not benefit from removal of any items.

Conclusions: The acceptable internal consistency score obtained verifies the validity and reliability of using the UL-MAS as an independent scale. This study has also verified the construct validity of the UL-MAS subscale and provides a valuable extension of previous work, which together demonstrates the value of the UL-MAS as a responsive, valid and reliable measure of upper limb function in adults following stroke. The UL-MAS produced a single, composite score that could be interpreted as a total score for upper limb function in this population.     

Psychological factors after traumatic amputation in landmine survivors: The bridge between physical healing and full recovery

Purpose: Limb loss due to a landmine injury is sudden and devastating. The resulting disability makes life challenging in a world where physical ability is the 'norm'. In order to better understand the psychological adjustments individuals make in their recovery from a landmine injury, the Landmine Survivors Network conducted an exploratory qualitative study to determine factors that contribute to an individual's recovery. The study examined psychosocial aspects, coping strategies, and resilience characteristics of limb loss survivors across differing cultural, societal and economic backgrounds.

Method: Eighty-five participants (68 persons of limb loss, 10 family members, seven service providers) were interviewed using a semi-structured protocol in the USA and an open-ended format in six landmine affected countries. Data analysis was completed using grounded theory analytic strategies.

Results: Data indicated that the survivors' acceptance of limb loss and their state of psychological recovery were greatly influenced by the individual's resilience characteristics, social support, medical care, economic situation and societal attitudes toward people with disabilities.

Conclusion: Recovery from traumatic amputation in landmine survivors needs to be comprehensive and coordinated, and requires addressing the individual's physical, psychological, economic and social needs within the context of family, community, and the socio-cultural environment in which they live.     

The value of the Rehabilitation Activities Profile (RAP) as a quality sub-system in rehabilitation medicine

Purpose: To determine whether interdisciplinary team care, using the Rehabilitation Activities Profile (RAP) as a team tool, results in a better rehabilitation outcome.

Method: A multilevel prospective cohort study, with a controlled before and after design. Eighteen rehabilitation teams in eight rehabilitation centres in the Netherlands and Belgium participated. Based on the level of implementation of the RAP, we compared three study groups. Consecutive adult patients (n = 933) with stroke, amputation of the lower limb, spinal cord injury, multiple sclerosis, or other neuromuscular disorders, were followed during inpatient or outpatient rehabilitation. Main outcome measures were Barthel Index, RAP-CPM (sum score of the domains communication, personal care and mobility), Nottingham Health Profile (NHP), length of rehabilitation (LOR) and discharge destination (home vs elsewhere).

Results: Overall results show that scores on the Barthel Index, the RAP-CPM and the NHP improved, on average, by 18.4%, 12.7%, and 6.7%, respectively. However, treatment from a rehabilitation team that uses the RAP was associated with a significantly lower Barthel score, and small, non-significant effects on the RAP-CPM and the NHP. Partial use of the RAP resulted in non-significant, lower scores on these measures. With respect to discharge destination and LOR, there were also no significant differences between the three study groups, with the exception of a shorter outpatient rehabilitation period for the group in which partial use was made of the RAP.

Conclusion: The RAP, at the current level of implementation, does not improve rehabilitation outcome.     

Coping after trans-femoral amputation due to trauma or tumour—a phenomenological approach

Purpose: To describe, by use of a phenomenological approach, how relatively young trans-femoral amputees experienced their amputation and their coping strategies in the acute phase and over time.

Method: Eleven trans-femoral amputees, median age 33.5 years, were interviewed. The amputation was caused by tumour, motorcycle accidents or work-related traumas. Amputation was made in median 7.5 years before the interview. The informants were community dwelling and managed well indoors. One had a half disablement pension and all the others were working or studying full time. The interviews were tape-recorded and transcribed verbatim.

Results: Two themes emerged. In the first theme 'Experiences of the amputation' denial and avoidance were the coping strategies mainly used. In the second theme 'Coping strategies to relate to a new norm' the informants used downward comparison, positive comparison and repression. Only one informant indicated a full acceptance of his situation.

Conclusion: Relatively young, trans-femoral amputees within this sample, have not reached the acceptance level, though a long time has passed since the amputation. They might have benefited from professional support and guidance during the rehabilitation process in order to improve coping strategies to relate to a new norm.     

The experience of men using an upper limb prosthesis following amputation: positive coping and minimizing feeling different

Purpose. Psychosocial factors are likely to play a crucial role in adjustment to upper limb amputation and prosthesis use, and yet have received only minimal exploration within the literature. This study therefore, sought to gain a rich understanding of the experience of living with an upper limb amputation and of using a prosthetic arm and hand.

Methods. The qualitative method of Interpretive Phenomenological Analysis was used. Purposive sampling culminated in a homogenous sample of 11 males with unilateral upper limb amputations, who wore a prosthesis at least weekly. Semi-structured interviews were carried out, transcribed and analysed according to the methodology.

Results. Participants identified a theme of ongoing awareness of difference in appearance and ability. Consequently, participants described themes of psychosocial and functional adjustment to minimize this sense of difference. This was facilitated by the participants' prostheses and their positive coping style. Within this, participants also identified the personal meanings of their prosthesis and highlighted the terms of its use. The minimization of their sense of difference resulted in participants regaining a sense of worth.

Conclusions. The findings offer a greater psychological insight into adjustment from an upper limb amputation and the role of prostheses. These findings have implications for both the clinical rehabilitation of patients who undergo upper limb amputations, as well as for future research into the use and value of prostheses in facilitating the adjustment to this experience.     

A two-year longitudinal study of social support following amputation

Purpose: (1) To describe one aspect of social support, social integration, longitudinally for 2 years following lower limb amputation and (2) to explore the impact of social support on depression, pain interference, life satisfaction, mobility, and occupational functioning.

Method: Eighty-nine adults recruited from consecutive admissions to an orthopaedic surgery service completed telephone interviews 1, 6, 12 and 24 months following amputation surgery. Dependent variables included the Social Integration (SI) sub-scale of the Craig Handicap Assessment and Reporting Technique (CHART) and the Multidimensional Scale of Perceived Social Support (MSPSS).

Results: There was a high level of SI among most persons following lower limb amputations that was relatively unchanged in the 2 years following surgery. However, mean levels of SI were lower in this group compared to a sample without disabilities. MSPSS scores were highly variable, ranging from almost no support to the maximum amount of support. MSPSS was an important concurrent predictor of pain interference, life satisfaction, and mobility, controlling for demographic and amputation-related factors. Baseline MSPSS predicted mobility and occupational functioning 6 months post-amputation, controlling for demographic and amputation-related factors.

Conclusions: Findings suggest that interventions aimed at improving the quality of social relationships after amputation may facilitate participation in activities.     

Sexuality in persons with limb amputation: A meaningful discussion of re-integration

Purpose: Rehabilitation professionals do not appear to be sufficiently prepared to deal with the sexual issues of people with a physical disability, although they have recognized the value of discussing them during the rehabilitation process. This commentary argues that the sexuality of people with a disability should be evaluated from the two viewpoints of sexual function and sexual concern. With regard to people with a limb amputation, their sexual life has not attracted researchers' or clinicians' interest because their sexual function is usually preserved, is the same as that of able-bodied persons, and there is a perception that assistance is not required. Indeed, the number of published studies on the sexuality of this population is apparently fewer than the number of studies on the sexuality of persons with central nervous system impairment.

Conclusion: Investigation of the body image of people with a limb amputation and recognition of their needs are considered to be necessary for further discussion of this theme. Discussion of sexuality with some realistic statistical figures should also have great value in assisting with the re-integration of people with a limb amputation.     

A study of the physical rehabilitation and psychological state of patients who sustained limb loss as a result of terrorist activity in Northern Ireland 1969-2003

Objective. To benchmark the psychological state and physical rehabilitation of patients who have sustained limb loss as a result of terrorist activity in Northern Ireland and to determine their satisfaction with the period of primary prosthetic rehabilitation and the artificial limb.

Method. All patients who sustained limb loss as a result of the Troubles and were referred to our rehabilitation centre were sent a questionnaire. The main outcome measures were the SIGAM mobility grades, the General Health Questionnaire (GHQ12) and three screening questions for Post Traumatic Stress Disorder (PTSD).

Results. Out of a 66% response rate, 52 (69%) patients felt that the period of primary prosthetic rehabilitation was adequate; 32 (54%) lower limb amputees graded themselves SIGAM C or D; 45 (60%) patients stated that they were still having significant stump pain. Significant stump pain was associated with poorer mobility. Nine (56%) upper limb amputees used their prosthetic limb in a functional way; 33 (44%) patients showed “psychiatric caseness” on the GHQ 12 and 50 (67%) had symptoms of PTSD.

Conclusions. Most patients felt that the period of physical rehabilitation had been adequate; those who did not were more likely to be having ongoing psychological problems. A high percentage of patients continue to have psychological problems and stump pain.     

Long-term outcomes after moderate to severe traumatic brain injury

Objective: This research examined the long-term outcomes of rehabilitation patients with moderate to severe traumatic brain injury (TBI).

Design: Retrospective cohort study.

Setting and subjects: We examined consecutive records of persons with moderate to severe traumatic brain injury who were discharged from a large rehabilitation hospital in Pennsylvania from 1973 to 1989. We interviewed consenting participants (n = 306) up to 24 years post-injury.

Main outcome measures: Self-rated health, activity limitations, employment, living arrangements, marital status, Community Integration Questionnaire, and use of rehabilitation services.

Results: Participants were most limited in activities such as managing money and shopping. Twenty-nine per cent of our participants were working full time. There were significant relationships between activity limitations and residual cognitive impairment at follow-up. Self-rated health was correlated with most instrumental activities of daily living.

Conclusion: Our findings document health and function in a large post acute TBI population and implications for rehabilitation are discussed.     

Toward a cognitive-affective model of goal-setting in rehabilitation: is self-regulation theory a key step?

Purpose: The aim of this article is to argue that self-regulation theory might offer a useful model for clinical practice, theory-building and empirical research on goal-setting in rehabilitation.

Method: Relevant literature on goal-setting and motivation in rehabilitation is considered and some problematic issues for current practice and future research are highlighted. Carver and Scheier's self-regulation theory and its application to rehabilitation research is examined.

Results: It is argued that self-regulation theory offers a robust theoretical framework for goal-setting and one in which the salient concepts of motivation and emotion are prominent.

Conclusions: Self-regulation theory offers a potentially useful heuristic framework for rehabilitation research.
