Direction and shaft tilt
The flexible joint permits multidirectional shaft movement created by the user.
FOR PROFESSIONALS
Give movement a precise
mechanical reference
PlyoDyne gives physiotherapists, rehabilitation teams, trainers and researchers a consistent system in which mechanical settings and task instructions can be changed deliberately.
01 — WHAT CAN BE VARIED?
Eight task variables.
One consistent reference.
Seven variables arise from the equipment configuration. Movement speed is created by the user in response to the professional’s instruction.
Movement range
The height-adjustable Range Control Ring changes the available shaft-tilt envelope.
Support-handle height
The support-handle assembly moves vertically to suit the user’s body dimensions, starting position and intended exercise.
Degree of shaft support
The shaft can move freely, be range-limited or rest against the ring.
Handle position
The keyed handle travels freely along the straight shaft while remaining rotationally coupled to it.
Rotation
The shaft and handle rotate together through the bearing above the flexible joint.
Added mass and inertia
The S-handle accepts weights in combinations beginning at 25 g; the M configuration also provides a lightweight handle and a 1.9 kg lightweight exercise shaft.
Movement speed
Speed is not set by the machine. The professional defines the task and the user creates the movement.
02 — THREE EQUIPMENT STATES
Structure the shaft
to fit the question.
Free movement
The shaft moves freely around the flexible joint.
Range-controlled
The Range Control Ring limits how far the shaft can tilt.
Supported shaft
The shaft rests against the ring for a more stable reference.
These are equipment states, not a treatment protocol. There is no universal PlyoDyne sequence from supported to free movement.
03 — PROFESSIONAL FRAMEWORK
Define. Observe.
Adjust. Reassess.
Define the task
Set a clear purpose and observable outcome.
Choose variables
Select range, support, speed and mass deliberately.
Observe
Separate task success, movement quality and demand.
Reassess
Treat an individual response as an observation—not general proof.
Explore adjustable tasks within your own professional framework.
- Review the mechanics before considering an application.
- Use professional judgement for suitability and supervision.
- Define appropriate stopping criteria.
- Do not infer clinical effectiveness from an individual response.
Combine variables without a pre-programmed trajectory.
- Start with a clear movement objective.
- Change one or more variables deliberately.
- Separate movement quality, task success and training demand.
- Do not translate training observations into medical claims.
PlyoDyne® allows added mass to be changed in increments as small as 25 g. This gives professionals a precise way to document and test gradual load changes over successive sessions, while deciding progression from the user’s response rather than assuming an outcome.
Compare productsInvestigate a reproducible mechanical platform.
- Define the equipment state and task instruction explicitly.
- Record range, support, shaft/handle configuration and added weight.
- Choose independent outcome measures and study controls.
- Treat hypotheses and observations separately from evidence.
