Karma EvO Altus Standing Power Wheelchair

The EvO Altus represents Karma Medical’s flagship standing power wheelchair, combining seated mobility with powered standing capability. Winner of the 2018 Red Dot Design Award, this wheelchair enables users to transition between sitting and standing positions independently.

Product Overview

Designed for users with limited lower limb function who benefit from standing therapy, the EvO Altus addresses both mobility and health maintenance needs. Standing positions help improve circulation, bone density, and social interaction at eye level with others.

The wheelchair accommodates users with varying levels of body control through four distinct standing modes, allowing clinicians to match the standing sequence to individual physical capabilities.

Key Features

Four Standing Modes

The EvO Altus offers multiple pathways to standing position:

• Direct sit-to-stand for users with adequate trunk control
• Lying-to-standing sequence for users requiring gradual transition
• Tilt-first modes that redistribute weight before elevation
• Customizable sequences based on user tolerance

Tilt-in-Space Function

The 45-degree tilt-in-space system maintains the seat-to-back angle while tilting the entire seating unit. This function:

• Redistributes pressure from buttocks to back
• Improves sitting stability during transport
• Reduces sliding and shear forces

Recline System

The backrest reclines from -5 degrees forward tilt to 180 degrees flat position, enabling:

• Full lying position for pressure relief
• Multiple rest positions throughout the day
• Transfer positioning flexibility

Technical Specifications

Designed for standing therapy and pressure management, the EvO Altus offers four configurable standing modes, 0°–45° tilt-in-space, and a backrest that reclines from -5° forward tilt to 180° flat.

Clinical Applications

Pressure Management

Standing redistributes pressure from the ischial tuberosities, reducing pressure ulcer risk for users who cannot perform weight shifts independently. The tilt and recline functions provide additional pressure relief options.

Bone Health

Regular standing loads weight through the lower extremities, potentially reducing bone density loss associated with prolonged sitting. Standing programs may be prescribed as part of full rehabilitation protocols.

Functional Activities

Standing height enables:

• Eye-level conversation
• Kitchen and workspace access
• Reaching elevated storage
• Participation in standing social activities

Regulatory Status

Awards and Recognition

The EvO Altus received the 2018 Red Dot Design Award, recognizing its combination of functional innovation and aesthetic design. The award committee noted the wheelchair’s ergonomic approach to enabling independent standing mobility.

Frequently Asked Questions

Who is the EvO Altus designed for?

The EvO Altus suits users with lower limb paralysis or weakness who can benefit from standing but cannot stand independently. This includes individuals with spinal cord injuries, multiple sclerosis, and other conditions affecting leg function. Users should have adequate upper body and trunk stability or appropriate positioning supports.

How does the standing function compare to standing frames?

Unlike stationary standing frames, the EvO Altus allows powered mobility while standing, enabling users to move around standing height workspaces. However, the standing duration and weight-bearing characteristics differ from traditional standing frames used in therapy settings.

What maintenance does the EvO Altus require?

As a complex power wheelchair with multiple actuators and electronic systems, the EvO Altus requires regular maintenance by qualified technicians. Battery care, actuator inspection, and control system calibration should follow manufacturer schedules.
