Key Limitations

• Short capture / low cycle count: interpret asymmetries and variability conservatively.

Findings

Gait Timing Descriptors

Key metrics snapshot

• Primary cycles: 3

• No findings in this context at current severity threshold.

Rules evaluated

• insufficient_cycles: PASS (rule=insufficient_cycles)
• low_evidence: PASS (rule=low_evidence)

Gait Left/Right Difference Descriptors

Key metrics snapshot

• Primary cycles: 3

• No findings in this context at current severity threshold.

Rules evaluated

• step_time_difference: PASS (rule=step_time_difference)
• stance_proxy_difference: PASS (rule=stance_proxy_difference)

Stride-to-Stride Variability Descriptors

Key metrics snapshot

• Primary cycles: 3

• No findings in this context at current severity threshold.

Rules evaluated

• stride_time_variability: PASS (rule=stride_time_variability)

Balance-Related Movement Quality Proxies

Key metrics snapshot

• Primary cycles: 3

Rules evaluated

• trunk_sway_proxy: MILD (rule=trunk_sway_proxy)

• MILD - Thorax movement relative to the pelvis was elevated across stride windows. This wrap-safe orientation descriptor is a movement-quality proxy, not a clinical balance diagnosis.

Baseline-Relative Movement Change

Key metrics snapshot

• Primary cycles: 3

Rules evaluated

• baseline_not_available: INFO (rule=baseline_not_available)
• high_deviation: PASS (rule=high_deviation)

• INFO - Robust baseline-relative z-scores were not calculated because a repeated, protocol-matched baseline distribution was not available.

• metric: baseline_robust_z_distribution
• status: not_evaluated
• reason: repeated_baseline_distribution_unavailable
• requirement: protocol-matched repeated baseline observations are required
