Objective metrics in rehabilitation: from "I think they improved" to citable data

Accuracy, success count, reaction time, and level trends — four metrics that turn a clinician's hunch into evidence.

"I think they did better this week." Honest — but fragile. Memory is biased, and noisy sessions make judgment hard. An objective metric is the same observation, but recorded, standardized, and comparable.

Four core metrics in BodyVR

Accuracy: successful attempts over total attempts — the overall quality picture.
Success / miss counts: the real volume of useful practice per session.
Reaction time (time to success): processing and movement-initiation speed — the most sensitive marker of subtle change.
Level trends: where the patient sits on the challenge curve, and how steeply they are climbing.

Clean data comes first

A metric is only citable when it is noise-free. That is why BodyVR uses a two-phase flow: preparation and warm-up moments never enter the statistics. The clinician sees a report that narrates only real practice — and the patient and family get the same story in plain language.
