Effect of Proprioceptive Knee Braces on the Performance and Endurance of Recreational Soccer Players Aged 60-80 Years

Study Overview
=================
Brief Summary
-----------------
The objective of the study is to evaluate the effect of wearing bilateral proprioceptive knee braces on the endurance of subjects aged 60 to 80 years.

Detailed Description
-----------------
Sporting activity has proven health benefits, particularly for older adults, whose balance and neuromuscular functions decline with age. On the other hand, physical activity in the elderly population may be hampered by inadequate physical condition, muscle or proprioceptive deficits, or fear of falling or injuring. A proprioceptive knee brace could therefore make physical activity safer and thus improve performance, balance, and ultimately the quality of life of the participants. The objective of the study is to evaluate the effect of wearing bilateral proprioceptive knee braces on the endurance of subjects aged 60 to 80 years.

Design Details

Primary Purpose: Other
Intervention Model: Single Group Assignment
Interventional Model Description: This is a prospective, monocentric, randomized clinical investigation (order of tests with and without knee braces), carried out in open, over a period of 2 weeks (cohort 1) or 12 weeks (cohort 2), in a population of people aged 60 to 80 years practicing recreational soccer.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: self-comparison<br>Volunteers will be asked to wear a knee brace on each limb during one of the training sessions. At the end of this training session, a questionnaire will be given to the volunteer to evaluate knee stability, range of motion, confidence when walking, and fear of falling. The volunteers will then have to participate in 2 test sessions: one with and one without knee braces. The patient will perform tests (Unipodal balance on flat ground, 30s chair stand test, 2,5m up and go test, 6 min-walk) with and without the proprioceptive knee brace in a randomized order. At the end of the tests with and without knee brace, a questionnaire will be given to the volunteer to evaluate the stability of the knee, the range of motion, the confidence when walking, the fear of falling, as well as a satisfaction questionnaire about the device. There is also a satisfaction questionnaire regarding the proprioceptive knee brace to be completed at the end of the study. | Device: proprioceptive knee braces<br>* The patient will perform the tests with the knee braces.<br>Device: No knee brace<br>* The patient will perform the tests without the knee brace.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluate the effect of bilateral proprioceptive knee braces on the endurance of subjects compared to without knee brace. | The evaluation of the subjects' endurance corresponds to the difference in results obtained during the 6-minutes walk test in the absence and presence of knee braces. | week 1 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluate the impact of knee braces on balance compared to without knee brace. | Balance will be evaluated via a unipodal balance test performed on flat ground, eyes open and eyes closed, and the result of the test compared in the absence and presence of knee braces. | week 1 | 
| Evaluate the impact of knee braces on lower limb strength compared to without knee brace. | The strength of the lower limbs will be evaluated via the 30s chair stand test and the result of the test compared in the absence and presence of knee braces. | week 1 | 
| Evaluate the impact of knee braces on walking speed compared to without knee brace. | Walking speed and agility will be evaluated during the 2.5m up and go test and the test result compared in the absence and presence of knee braces. | week 1 | 
| Evaluate the impact of knee braces on the volunteer's feelings about the stability of his knees, their range of motion, his confidence when walking and his fear of falling after the tests and after the training | The feeling of the volunteer will be evaluated via a questionnaire on the stability of the knee, the amplitude of movement, the confidence during the walk and the fear of falling felt after the tests and after the training | week 1, week 2 | 
| Evaluate the influence of the functional capacity of the knees of each volunteer at inclusion on the various performance parameters measured | The functional capacity of the knees at inclusion will be assessed via the Lysholm questionnaire | Day 0 | 
| Evaluate the satisfaction of the volunteers with the device | The volunteers' satisfaction with the system will be evaluated via a specific satisfaction questionnaire. | Last visit | 
| Evaluate the tolerance of the knee braces | Tolerance will be evaluated through the collection of adverse events following the wearing of knee braces | week 1, week 2 |
