When someone is in pain, the most important measurement question is not "where does it hurt?"
The person has already answered that.
The question is: what does the body do when the painful area is asked to work?
What the Sensor Sling Is
The I AM 900 Sensor Sling is a fabric-supported measurement device. It is worn around the region being assessed and holds sensor zones against the skin so the instrument can record the physical response during a defined movement task.
It is a measurement instrument — not a support garment, not a treatment device and not a diagnostic tool.
What It Records
Where supported by the instrument configuration, the Sensor Sling records:
- distributed Sling pressure — how force is organised across the Sling's sensor zones
- sensor-zone response — how individual zones respond as the task progresses
- angle and orientation — the Sling's measured orientation as the body moves
- changes over time — how the recorded response evolves during the task
- timing — when events occur in the task
- sequence — the order events occur in
- repeatability — whether the response is consistent when the task is repeated
- speed / rate of change — how quickly the recorded response moves, where the configuration supports it
Not every assessment measures every variable. The measurement set is chosen to fit the question being asked.
What It Does Not Record
The Sensor Sling does not directly measure any of the following:
- ligament strain
- tissue damage
- inflammation
- nerve compression
- psychological trauma
- pain intensity
- pathology
These are things that live inside biology, experience and tissue — not things a contact-pressure instrument can see. No claim that the Sling measures any of them is made here, because the instrument does not do that.
Why This Matters When Someone Is in Pain
Pain is the person's experience. It is real, it matters and it is recorded in its own right — pain score, reported restriction, reported confidence.
The Sensor Sling answers a different question: what does the recorded physical response look like during a defined task?
THE PERSON REPORTS THE EXPERIENCE.
THE SLING RECORDS THE PHYSICAL RESPONSE.
NEITHER SUBSTITUTES FOR THE OTHER.
A person can report high pain and record a stable response. A person can report little pain and record an asymmetric response. Both findings are information. Neither is a diagnosis.
In Pain Assessment, the Sling Is One Part of the Baseline
A pain baseline in I AM 900 holds several information sources side by side:
- the pain score and what the person reports
- the Sensor Sling measurement under a defined task
- pressure-mat ground and contact loading, where used
- the movement task itself — the physical context
On retest, the same task is repeated and both sides are compared with the baseline: what changed in what the person reports, and what changed in what was recorded.
MEASURE → CALIBRATE → RETEST.
