About this study
Official title: Effects of Muscle Strength Training in Lower Limb Amputee Patients
This study is a clinical trial that evaluates the best treatment option using a strength training protocol and an endurance training protocol in patients with lower limb amputations who use prostheses. The protocol consists of 6 weeks of strength training and 6 weeks of endurance training, with a 1-month washout period between the two.
Read the detailed description
The assessments in this study focus primarily on strength, using a dynamometer and the 5 RM, functionality, using the AMP scale, mobility, using the TugTest, quality of life, using the WHOQOL-BREF, and perception of change, using the GROC.
- Conditions
- Lower Limb Amputation
- Being tested
- Muscle strengh training, Resistence training
- Keywords
- amputees, quality of life, funcionality, muscle strength, movility, endurance training
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Muscle strengh trainingOther
Strength training lasts six weeks, during which submaximal strength percentages ranging from 75% to 90% are worked on.
It is performed three times a week and follows a protocol consisting of progressive exercises for the large functional muscle groups relevant to the population being trained.
Resistence trainingOther
Resistance training will be carried out for 6 weeks, 3 times a week, with exercises prescribed by a protocol with training characteristics defined by bibliography found in the ACSM.

It is performed three times a week and follows a protocol consisting of progressive exercises for the large functional muscle groups relevant to the population being trained. Receives: Other: Muscle strengh training |

What is being measured
The primary outcome is the main question the study is designed to answer.
Changes in Funcionality
It is assessed using the TUG test, which requires patients to get up from a chair, walk 3 meters, turn around, walk back to the chair, and sit down again. Patients will receive the following instructions: "Get up on the word 'go,' walk to the tape, turn around, walk back to the chair, and sit down."
Measured: day 1, day 18 (last day of week 6), day 1 (after the wash out) and day 24.
Changes in quality of life
It is assessed using a self-administered questionnaire called WHOQOL-BREF, which provides a profile of the person's perceived quality of life.
Measured: day 1, day 18 (last day of week 6), day 1 (after the wash out) and day 24.
Secondary outcomes (3)
Changes in Maximum isometric muscle strength
It is evaluated using a dynamometer, in which three measurements are taken for each designated movement and the average of the maximum force and peak force is calculated.
Measured: day 1, day 18 (last day of week 6), day 1 (after the wash out) and day 24.
Changes on Movility
It is assessed using the AMP functional rating scale (amputee mobility predictor).
Measured: day 1, day 18 (last day of week 6), day 1 (after the wash out) and day 24.
Change in Global percepcion of change
It is an assessment carried out using the Groc scale, which evaluates changes in perception.
Measured: assessments were performed at the end each protocol. day 18 and day 24
