Walking versus skating

On 55 accepted same-day Mall skating, pain-limited Walking, and PT skating dates, the measured mechanical direction repeated while skating produced much more useful distance. Walking's pain-limited function is reported separately from chest-accelerometer measurements. Paired vertical RMS describes movement acceleration, not pelvic force or pain. The distance comparison describes functional output; A2 per self-propelled mile relates measured exposure to that output. Per-minute intensity and per-mile cost answer different questions. Expand the data tables to inspect the source denominators, paired uncertainty, and native-recording versus governed-stage boundaries. This is a completed N-of-1 protocol, not a claim that every other person's movement will behave the same way.
