During any period of rehabilitation it is important to select meaningful tests that; measure
what you want, are responsive to changes in the patient's condition and, easy to use in the
clinical settings. With an amputee such tests may help make sure that rehabilitation
programmes and the prosthesis (artificial leg) provided are tailored for the individual. New
prosthetic technology is continually being developed and the active amputee now demands more
from their artificial limbs. Making sure that they get the right rehabilitation programmes
and the most appropriate prosthesis will help them perform to their best.
Thirty amputees who have recently undergone a lower limb amputation will be recruited into
this study. They will be asked to complete 2 walking tests and 4 questionnaires that measure
different aspects of their recovery from the comfort of the socket to their perceived
ability to undertake everyday tasks. Each of the tests give a score or grade which
represents the level of their ability, as judged by the test, at that given time point. The
tests will be repeated at one and three weeks after delivery of their prosthesis, just
before discharge from hospital and at 6 weeks post-discharge.
By measuring the changes in the scores across these time points, and also how the amputees
feel they have changed, it is hoped that it can be determined how responsive the tests are
to objective measures of changes in the amputees abilities and also whether the tests are
sensitive to the changes felt by the amputee. If it is shown we can more accurately link
changes in the scores to the changes in the amputees abilities then Physiotherapy treatment
programmes could be more accurately tailored to the individual amputee.

Other | Establish the minimal detectable changes (MDC) for each of the Outcome Measures | b. In a subset of participants, establish the minimal detectable changes (MDC) for the Physical Function OMs, through test-retest measurements. | 24hrs | No |
Primary | The changes in scores in all tests during early rehabilitation period. | The changes in scores in all Outcome Measures during Time Period 1 and Time Period 3 will be recorded. For each Outcome Measure during each time interval the effect size (ES)will be calculated, using the formula below. These will serve as a statistical description of the sensitivity to change or responsiveness of each Outcome Measure. ES = mean diff (SV1-SV2) / (SD SV1-SV2) A higher ES value indicates higher responsiveness. |
2 weeks and 6 weeks | No |
Secondary | Mean scores and the score changes recorded in the two time periods under investigation, i.e. T1 and T3 will be compared within the different categories in the Activity Change Questionnaire. | The mean score difference between "equal" group and the "slightly better" group will result in the Minimal Clinically Detectable Change (MCDC) for improvement. The corresponding MCDC for worsening in the same time period will be determined by the mean score difference between the "equal" group and the "slightly worse" group. | 2 weeks and 6 weeks | No |
