The Ankle Machine: Portable Isokinetic Rehab for Ankle & Wrist

Velocity Isokinetics Ankle Machine — a compact, portable tabletop isokinetic unit with two strapped footplates for ankle and wrist conditioning

Not every rehabilitation task needs a full-size machine on the clinic floor. The Ankle Machine from Velocity Isokinetics is a compact, portable unit designed for ankle and wrist conditioning — a space-efficient tool that lets a practitioner move between movements without moving the client.

Originally known as the “Maxi Ankle & Wrist,” the unit now sits within the eight-machine Velocity range as a clinic-friendly option for therapists who need isokinetic resistance in a small footprint. Here is what it does, how it works, and where it fits in a rehab or conditioning setup.

A Portable Unit Built for the Clinic Floor

Space is at a premium in most physiotherapy and sports-medicine clinics, and the Ankle Machine is built around that reality. The footprint is just 0.7 metres wide by 0.7 metres long — small enough to live on a bench or trolley and be moved between treatment bays.

Key physical features include:

  • Portable and space efficient design
  • Heavy-duty frame and handlebar for stability under load
  • Wrist and feet attachments, so the one unit serves both upper- and lower-limb work

It is a tabletop unit rather than a standing frame, which makes it well suited to seated, controlled rehabilitation work where the practitioner needs close access to the joint.

Independent Two-Way Resistance You Can Dial In

The Ankle Machine’s defining feature is its adjustable, independent two-way resistance. Resistance can be set independently in each direction — a detail that matters in rehab, where a client recovering from injury often has very different strength on one side of a movement than the other.

Operation is deliberately simple:

  • 10 load settings give the practitioner a wide gradient of resistance to progress through
  • Variable speed control from 10 deg/sec to 300 deg/sec spans the range from slow, controlled rehab work up to higher-speed conditioning
  • Easy-to-use axis rotation lets you switch between movements without moving the client or the machine

That two-way, independently set resistance reflects the same dual-direction philosophy that runs through the wider Velocity range — engaging muscle contraction in both directions of a movement rather than just one. Read more on the principle in Dual Concentric Training, or see how it differs from conventional strength equipment in Isokinetic vs Isotonic vs Pneumatic.

Ankle Movements: Plantar/Dorsi and Inversion/Eversion

For the lower limb, the machine covers the two ankle movement pairs that matter most in rehabilitation:

  • Ankle plantar/dorsi flexion — pushing the foot down and pulling it up
  • Ankle inversion/eversion (technically occurring at the subtalar joint) — rolling the foot inward and outward

That combination makes the unit relevant across a range of clinic use cases: post-sprain strength and proprioception work, post-operative ankle rehab, return-to-play assessment, and general lower-limb conditioning where controlled speed is the goal. Because the resistance is set at a controlled speed and can be dialled to a low setting, the practitioner can keep a recovering joint working through a full range of motion while managing the load applied — a key reason isokinetic resistance is widely used in rehab settings.

Wrist and Forearm Conditioning

The Ankle Machine is not only for the lower limb. With the wrist attachment fitted, the same unit covers upper-limb movements:

  • Wrist flexion/extension and pronation/supination
  • Forearm pronation/supination and elbow flexion/extension

That makes it a useful two-in-one tool for clinics treating hand, wrist and forearm cases alongside lower-limb work — a genuinely versatile wrist rehab device when the footplate is swapped for the wrist attachment.

Data and Reporting

Like the wider Velocity range, the Ankle Machine can be paired with the Computer Managed Training System (CMTS) — listed as an optional extra on this unit — which produces reports across:

  • Strength
  • Power
  • Range of motion

Those read-outs let a clinician baseline a joint, track progress across a rehab block, and document outcomes. For more on why Velocity measures and stores power (in watts) rather than strength alone, see Power = Force × Velocity.

Who It Suits

The Ankle Machine is aimed primarily at rehabilitation and conditioning professionals — physiotherapy clinics, sports-medicine practices, and high-performance settings that need a portable isokinetic option for the ankle and wrist. Its strength is versatility in a small footprint: one unit, independent two-way resistance, and a speed range that runs from gentle rehab to faster conditioning — a portable ankle rehabilitation machine built for the modern clinic.
