Influence of Dental Occlusion on the Performance of High Level Rowers (IODPR) (IODPR)
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
Current literature data suggest that dental occlusion has an influence on postural control in the general population, and more markedly in high-level athletes. The link between dental occlusion and the postural stability of top athletes has been studied in several disciplines such as basketball, shooting, golf and running. There is currently no data in the field of rowing. But this sport requires optimal postural control for synchronous and symmetrical muscle solicitation.
The present study aims to evaluate the influence of dental occlusion on postural stability and the performance of high level rowers.
Our assumptions are as follows:
- Occlusal disturbance alters the muscular power developed by high level rowers
- occlusal disturbance alters the static postural stability of high level rowers

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
OTHER: Rowing training session
Power tests, balance and tonicity tests are performed eyes opened and eyes closed :
|
A silicon artificial occlusal disturbance is made from a mould of the rowers mouth and placed in the mouth during the training session. With artificial occlusal disturbance : Maximal Intercuspal Occlusion (MIO) with silicone splint increases the vertical dimension of occlusion of 1, 2 and 4 mm.
The training session is performed without occlusal disturbance

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Muscular power
Time Frame: At the time of inclusion
|
Muscular power (in Watts) developed by the high level rowers with the "leg press" test on a "Dyno concept 2" machine, with and without artificial occlusal disturbance.
Each test lasts 30 seconds.
The sequence consists in 2 tests and is performed twice with a resting period of 1 min between each recording.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Surface of the pressure center of the rower's feet
Time Frame: At the time of inclusion
|
Each test lasts 51.2 seconds. The sequence consists in 10 tests and is performed twice with a resting period of 1 min between each recording. During each test, the projected sway area (in mm², the area of the confidence ellipse containing 90% of the sampled positions of the foot pressure center on the statokinesigram) is extracted from the stabilometric platform |
At the time of inclusion
|
Velocity of the pressure center of the rower's feet
Time Frame: At the time of inclusion
|
Each test lasts 51.2 seconds. The sequence consists in 10 tests and is performed twice with a resting period of 1 min between each recording. During each test, the sway velocity (in mm/s) is calculated as the speed of displacement of the center of pressure of the foot as a function of the average position on the antero-posterior axis of the statokinesigram. |
At the time of inclusion
|
Tonicity of the para-vertebral muscles
Time Frame: At the time of inclusion
|
Tonicity of the para-vertebral muscles is evaluated with the postural test of Posterior-superior iliac spines (PSIS) with and without artificial occlusal disturbance. This PSIS test is performed eyes opened, in MIO position with and without artificial occlusal disturbance, The sequence of two tests is performed twice. During this test, the endpoint is qualitative: operator asymmetric thumbs' ascension reflecting asymmetric contraction of paravertebral muscles (abnormal response) or not (normal response). |
