ProActionClinic

ProActionClinic a mené plusieurs années de recherches et de synthèse de nombreux travaux scientifiques et a mis au point le coussin extensit.

Extensit est la bases d’une nouvelle stratégie d’approche des troubles posturaux et des maux de dos qui y sont probablement liés.

HAMSTRING STRAINS

« Pre-exercise routines are common practice for the majority of individuals participating in sport. Though the optimal pre-exercise routine is debated, stretching is also usually incorporated pre-exercise as it has been suggested to improve muscle flexibility, prevent muscle injury and enhance physical performance.

Hamstring strains are one of the most common, recurrent injuries experienced in the sporting world and often result in significant time out of sport and activity.

Decreased hamstring flexibility is suggested to be one of the predisposing factors for hamstring strains (1-16). »

Permanent  tension and shortening of hamstring is frequently combined with knee flexum : precise testing show that complete knee extension is lost ; also this is obvious  in standing position ; most of the time   iliopsoas muscles shortening is  simultaneously present at least due to flexion of thigh on the pelvis related to knee flexum .

As demonstrated with studies, shortening of hamstring correspond to shortening of iliopsoas muscles.(17)

For that reason , to avoid hamstring decrease of flexibility,  we suggest hamstring stretching to be combined with iliopsoas stretching .

Unfortunately, stretching  iliopsoas muscles is not easy ; proposed exercises show often no result  or are unperfectly executed and,  indeed, maintaining stretching position for an adequate  time is often uncomfortable.

The Extensit cushion induces a posture allowing a gradual, gentle, painless stretching and with programmable duration.
The patient may remain clothed, removing the belt. Supine, the sacrum is maintained by the nose of the cushion,the column is extended, so the two hip bones and the coxofemoral joints gently go down : the iliopsoas muscles stretch slowly.
And especially : this stretching is bilateral.

Extensit cushion can be used in complement with  other medical treatment : see scientific studies and  speak to your therapist !
