Crutches related questions

How much do they weight?

KMINA crutch weights approximately 2 lb (900 grams). In addition, due to the fact that they are lifted both with hands and forearms, the real feeling is lighter than with the conventional crutches.

Are they adjustable?

If your height is between 4’9” and 6’5” (145 cm and 195 cm) they can be adapted perfectly to your height with regulations every 0.6” (1.5 cm). They also fit perfectly to the length of the user’s forearm between these heights. If your height is not in that range, email us at

Do you have crutches with a completely horizontal forearm support?

One of our two differential characteristics is a 30º inclined forearm support so you can distribute your weight.


We do not want to move the supported weight from one point (hands) to another (forearms), we want to distribute it between hands and forearms.

user experience related questions

Will they suit me for my pathology?

We have tested KMINA crutches with different kind of users, from users with specific injuries to chronic users with different pathologies. We have also tested both patients with one crutch and two crutches.


With users of one crutch, we have tested them with users of different ages and it is working very well. In rehabilitation they are also working well for every injury (knee, hip, sprain, multi-trauma…)


Regarding chronic users, we have tested them with different kind of diseases (hemiplegia and other brain diseases) and they are working well. The unique exception in which users have difficulties to get adapted to KMINA crutches is polio patients.

Can I use them walking up and down stairs?

Users have told us that they notice in greater proportion the advantages of KMINA crutches walking up and down stairs. The reason could be that in that moment hands and wrists are usually full loaded.
