“…Experienced transtibial prosthesis users are able to complete activities of daily living (ADLs) effectively, and the successful completion of these tasks is an integral part of regaining an independent lifestyle [1][2][3][4][5]. However, psychological issues, such as how an amputee feels about his or her amputation and prostheses, are also important factors.…”

Abstract-This study examined the longitudinal changes in generic health-related quality of life (QOL), prosthesis-related QOL, falls efficacy, and walking speed in men with lower-limb amputations up to 6 months following discharge from rehabilitation. Seven male unilateral transtibial amputees completed the Medical Outcomes Study 36-Item Short Form Health Survey, the Prosthesis Evaluation Questionnaire, and the Modified Falls Efficacy Scale at 1, 3, and 6 months postdischarge from rehabilitation. Walking speed was also recorded to objectively assess participants' mobility. Health-related QOL measures displayed increases, resulting in large effect sizes though not reaching statistical significance. Prosthesis-related QOL measures indicated that scales relating to the participants' prostheses improved and the support of significant others was the most positively scored variable. Walking speed increased by 0.12 m/ s, although it was not significantly related to indices of QOL or falls efficacy. Falls efficacy did not improve significantly during the study period, although it was strongly related to QOL (p < 0.05). These results provide a novel insight into how QOL and falls efficacy develop in people with lower-limb amputations, alongside changes in mobility, after discharge from rehabilitation. Further improvements in physical health following discharge may be required to elicit subsequent increases in overall QOL and concurrent improvements in falls efficacy.

Screening of patients for first time prostheses after amputation of lower limbs

Abstract. In the world's developed countries, demographic changes, such as aging societies and increased numbers of diabetes patients, have led to an increase in amputations (11), and it is believed that as society ages, the number of people who are older than 65 will face as much as two times more amputations [3].Of great importance after the amputation of a lower limb is the selection and adaptation of prostheses that allow patients to move around, thus achieving rehabilitation goals much more quickly [5].A 20090-study of the rehabilitation of people with lower limb amputations in Latvia found that among 183 patients, 50% use their prostheses actively for more than 6 hours a day, 30% did not use them at all or used them for less than 3 hours a day, and 20% used them for 3-6 hours a day.The study included 173 patients with lower limb amputations who were evaluated in 2012 in relation with whether primary prosthesis should be provided.Of 173 patients who were evaluated, only 109 received a decision on primary prostheses, while in 51 cases the process was delayed for 1-3 months, in 12 cases, it was decided that prostheses would not be purposeful.More than 25% of those who followed the recommended treatment and rehabilitation programme to prepare the amputation stump, reduced contracture and enhanced physical working abilities were declared to be appropriate for further prostheses. This indicates serious shortcomings in medical treatments during the early post-amputation period.

“…Pathological function of one or more of these physiological systems can be a contributing factor in falling [4][5]. Individuals with lower-limb amputations have reduced measures of postural stability [6][7][8][9] as determined by increased excursion of the center of pressure (CoP) and sway amplitude [9] in the mediolateral [6][7] and anteroposterior directions. Moreover, they identify postural stability as an important criterion for functioning with a prosthesis [10], and they have been shown to fall more than age-matched nondisabled individuals [11][12].…”

“…Most of our current understanding of postural stability of individuals with an amputation has been provided by various measures of movement of the CoP on a stationary [6][7][8][9][13][14] or unstable surface [6,[15][16]. Several studies have demonstrated increased excursion of the CoP in the anteroposterior direction [13,16] or both the anteroposterior and mediolateral directions [6][7]9,14].…”

“…Several studies have demonstrated increased excursion of the CoP in the anteroposterior direction [13,16] or both the anteroposterior and mediolateral directions [6][7]9,14]. Studies of individuals with lower-limb amputation have linked falling with movement of the CoP in the anteroposterior direction [8] and in individuals without amputation with a movement of the CoP in mediolateral plane [17][18][19].…”

Abstract-Appropriate muscular response following an external perturbation is essential in preventing falls. Transtibial prosthesis users lack a foot-ankle complex and associated sensorimotor structures on the side with the prosthesis. The effect of this lack on rapid responses of the lower limb to external surface perturbations is unknown. The aim of the present study was to compare electromyogram (EMG) response latencies of otherwise healthy, unilateral, transtibial prosthesis users (n = 23, mean +/-standard deviation [SD] age = 48 +/-14 yr) and a matched control group (n = 23, mean +/-SD age = 48 +/-13 yr) following sudden support-surface rotations in the pitch plane (toes-up and toes-down). Perturbations were elicited in various weight-bearing and limb-perturbed conditions. The results indicated that transtibial prosthesis users have delayed responses of multiple muscles of the lower limb following perturbation, both in the intact and residual limbs. Weight-bearing had no influence on the response latency in the residual limb, but did on the intact limb. Which limb received the perturbation was found to influence the muscular response, with the intact limb showing a significantly delayed response when the perturbation was received only on the side with a prosthesis. These delayed responses may represent an increased risk of falling for individuals who use transtibial prostheses.
