OBJECTIVES: (1) To measure the amount of cardiovascular stress, self-reported
physical activity, and accelerometry-measured physical activity by individuals
with spinal cord injury (SCI) during physical therapy (PT)
and occupational
therapy (OT); and (2) to investigate the relations between these measures.
DESIGN: Observational study. SETTING: Two inpatient SCI rehabilitation centers.
PARTICIPANTS: Patients with SCI (N=87) were recruited from consecutive admissions
to rehabilitation. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Heart
rate was recorded by a Holter monitor, whereas physical activity was captured by
self-report (Physical Activity Recall Assessment for People with SCI
questionnaire) and real-time wrist accelerometry during a total of 334 PT and OT
inpatient sessions. Differences between individuals with paraplegia and
tetraplegia were assessed via Mann-Whitney U tests. Spearman correlations were
used to explore the relation between measurements of physical activity and heart
rate. RESULTS: Time spent at a heart rate within a cardiovascular training zone
(>/=40% heart rate reserve) was low and did not exceed a median of 5 minutes. In
contrast, individuals reported at least 60 minutes of higher-intensity time
during therapy. There was a low but statistically significant correlation between
all measures. CONCLUSIONS: The cardiovascular stress incurred by individuals with
SCI during inpatient PT and OT sessions is low and not sufficient to obtain a
cardiovascular training effect to optimize their neurologic, cardiovascular, or
musculoskeletal health; this represents a lost opportunity to maximize
rehabilitation. Self-reported minutes of higher-intensity physical activity do
not reflect actual time spent at a higher intensity measured objectively via a
heart rate monitor.
