Assessing Functional Ability in Patients with Unilateral Trans-tibial Amputation for Vascular Disease

Functional capacity of elderly with lower-limb amputation after prosthesis rehabilitation: a longitudinal study

OBJECTIVES

Elderly amputees are a specific clientele because of the interaction of this disease with the ageing process. The objective of this study was to determine the impact of prosthesis rehabilitation on the functional capacity of elderly with lower-limb amputation (LLA) in short and long time.

MATERIALS AND METHODS

A quasi-experimental study was developed. The sample consisted of 29 elderly with LLA who finished the prosthesis rehabilitation programme. Gait capacity was evaluated by Functional Ambulation Classification Scale (FAC), ability to perform basic activities of daily living (ADL) was evaluated by Barthel Index (BI) and Pfeffer Questionnaire was used to evaluate the capacity to execute instrumental ADL. Statistical inference was done by t-test, t-student test and chi-squared test. The significance level was fixed at 5% (p < 0.05).

RESULTS

In the transtibial group (n = 15) no difference (p = 0.108) was found between BI score before amputation and after 3 months of follow up. The transfemoral group (n = 14) improved significantly (p = 0.045) the FAC before starting and after 3 months of discharge from ambulatory rehabilitation. Both groups increased the time of prosthesis use during the day after 3 months of follow up. However, no group has achieved FAC and Pfeffer Questionnaire pre-amputation performance.

CONCLUSION

Although elderly with LLA improved functional capacity after 3 months of a prosthesis rehabilitation programme, they did not achieve their pre-amputation functionality.Implications for rehabilitationLower-limb amputation causes a significant socioeconomic impact and decreases functional capacity, autonomy and quality of life. Elderly people with a lower-limb amputation impose a heavy burden on health resources, requiring extensive rehabilitation and long term care. The specific presentation of elderly persons with lower-limb amputation, with multiple physical, psychological, cognitive, and social comorbidities, imposes unique challenges to ongoing care. The potential bias from the inclusion of younger patients into a study with an elderly population with lower-limb amputation supports the need for independent investigation.In our study we verified that although elderly with transfemoral or transtibial amputation have improved their functional independence after lower-limb prosthesis rehabilitation, they could not achieve their functional capacity before amputation. This improvement especially occurred for the basic activities of daily living, however elderly patients with transfemoral amputations presented greater difficulty in improving functional capacity.These results support that being able to better select elderly by their mobility potential and environmental barriers, is an important goal for future research to aim toward those who will achieve and maintain prosthetic walking or those who could better focus on regaining nonprosthetic mobility.

Activities of daily living in people with lower limb amputation: outcomes of an intervention to reduce dependence in pre-prosthetic phase

PURPOSE

The main objective was to assess the change in the functional independence in basic activities of daily living (ADL) following a pre-prosthetic intervention in people with lower-limb amputation (LLA). Secondary objectives were to identify the factors contributing to the success of this intervention, and to analyze the effects on the presence of unmet needs for home adaptation.

METHOD

The ADL intervention was early and pre-prosthetic; it was focused on six self-care activities. Fifty-two adults with LLA, who required assistance in self-care, were included. Functional independence (Barthel) was assessed at baseline and after intervention (T2). Successful intervention was defined as independent performance of all self-care activities.

RESULTS

There was a significant improvement in Barthel scores between baseline and T2 in toileting (p < 0.001), bed-chair transfers (p < 0.001), dressing (p < 0.001), bathing/showering (p < 0.001), and feeding (p = 0.025). The proportion of homes with an unmet need for adaptation decreased significantly in bathroom (p = 0.008) and other internal areas (p = 0.031). Intervention was successful for 61.5% of participants. In a multivariate model, age was significantly associated with successful intervention (OR 0.66, 95%CI 0.52-0.83).

CONCLUSIONS

A short and pre-prosthetic ADL intervention improves functional independence and reduces the need for home adaptation. ADL programs should be included in rehabilitation strategies. Implications for Rehabilitation Because basic activities of daily living (ADL) can be seriously compromised after a lower-limb amputation, it is important for this population to improve or maintain their level of independence. A short and pre-prosthetic ADL intervention is an effective method for an early recovery of functional independence in self-care activities and promotes home adaptation. Age is an important determinant of functional recovery, and most subjects can achieve independence in basic ADL regardless of the level of amputation. A pre-prosthetic ADL program should be included in rehabilitation strategies for adults with lower-limb amputation.
