What are the Dnsys Z1 knee modules and who are they for?
The answer in detail
Dnsys's X1 assists the hip. The Z1 modules add assistance at the knee, with miniaturized electric actuators placed on each side of the joint. They are sold as bundles with the X1 Carbon, in bilateral form, the Z1 DualJoint, or unilateral form, the Z1 SingleJoint left or right.
According to our pages, they assist extension, in support and climbing phases, and regulate flexion, in descents and landings. This is not medical advice: these elements describe what the manufacturer states, not a demonstrated effect. They address people seeking powered assistance, not a treatment or supervised rehabilitation.
What the pages say
| Bundle | Description | Price |
|---|---|---|
| X1 Carbon + Z1 DualJoint | bilateral hip and bilateral knee | 2,198 dollars |
| Z1 SingleJoint left + X1 Carbon | bilateral hip and left knee | 1,598 dollars |
| Z1 SingleJoint right + X1 Carbon | bilateral hip and right knee | 1,598 dollars |
Communication between the X1 and the Z1 goes through a proprietary low-latency wireless protocol, under 5 milliseconds according to the page. The SingleJoint is presented for unilateral situations, such as weakness in a single knee. In every case, the module is used with the X1: it is not worn alone and adds one more device to adjust, charge and maintain.
How to decide
- Identify whether the discomfort affects one knee or both.
- Before buying, ask a doctor or health professional's opinion about your condition.
- Compare with simpler support, such as a knee brace or support tights.
- Add the weight and cost of the bundle, and import taxes on the dollar prices.
- Check the warranty, one year on our pages, and the return conditions in writing.

- A powered knee module is not presented as a treatment.
- The bundle costs 1,598 to 2,198 dollars, without import taxes.
