Hydraulic & Pneumatic knee joint
The nature of hydraulic knee joints and pneumatic knee joints are different. How should patients determine which type they belong to?
The need for walking and activities with prosthetics,
If the user is relatively young and expects to walk faster after wearing a prosthetic limb, has more willingness to go out and has a certain change in walking speed, hydraulic joints can provide more support in this regard.
If the user does not have such high requirements on the walking speed of the prosthetic limb, and the range of motion is mostly indoor flat ground or some outdoor flat ground, users who do not have too high requirements for walking speed and changes can consider the pneumatic knee joint.
¥ Prosthetic budget and economic considerations
Price is also often a very important consideration for users when choosing a prosthesis. If it is based on economic considerations, then you can choose a pneumatic joint.
Because the structure of the pneumatic system is relatively simple than that of the hydraulic system, the production process is relatively simple, the production cost is low, and the price is naturally low.
Are pneumatic joints more flexible than hydraulic joints? wrong!
But in fact, we cannot simply evaluate a joint by its flexibility, whether it is a pneumatic joint or a hydraulic joint, its flexibility during the swing period, its pneumatic/hydraulic system, mechanical structure, prosthetic alignment, etc. All factors are related.
Are hydraulic joints heavier than pneumatic joints? wrong!
In the market, some hydraulic joints are smaller and lighter than pneumatic joints, so it is unscientific to evaluate and compare the two joints simply by weight.
