Cross-sectional study.
Objectives:
To validate heart rate (HR) indexes for the evaluation of energy expenditure during wheelchair propulsion in people with spinal cord injury (SCI).
Setting:
SARAH Rehabilitation Hospital Network—Brasilia, Brazil.
Methods:
Forty-eight men aged 29.0±7.8 years with a SCI between C6 and L3 causing complete motor impairment were enrolled in the study. The assessment consisted of 5 min of rest while seated in the wheelchair, followed by 5 min of wheelchair propulsion at a self-selected comfortable speed. The main outcomes measured were oxygen consumption, HR, physiological cost index (PCI), total heart beat index (THBI) and propulsion cardiac cost index (PCCI).
Results:
Using oxygen uptake as gold standard, the highest correlations were found between this and PCCI (

Cross-sectional study.
Objectives:
To validate heart rate (HR) indexes for the evaluation of energy expenditure during wheelchair propulsion in people with spinal cord injury (SCI).
Setting:
SARAH Rehabilitation Hospital Network—Brasilia, Brazil.
Methods:
Forty-eight men aged 29.0±7.8 years with a SCI between C6 and L3 causing complete motor impairment were enrolled in the study. The assessment consisted of 5 min of rest while seated in the wheelchair, followed by 5 min of wheelchair propulsion at a self-selected comfortable speed. The main outcomes measured were oxygen consumption, HR, physiological cost index (PCI), total heart beat index (THBI) and propulsion cardiac cost index (PCCI).
Results:
Using oxygen uptake as gold standard, the highest correlations were found between this and PCCI (
r
=0.59,
P
<0.001, 95% confidence interval (CI) 0.36–0.75) and THBI (
r
=0.58,
P
<0.001, 95% CI 0.36–74.0), independently of the injury level. The PCI had the lowest correlation coefficient (
r
=0.38,
P
<0.01, 95% CI 0.11–0.60). Spearman correlation analysis showed that the indexes mostly associated with lesion level were PCCI (
ρ
=−0.531;
P
<0.001; 95% CI −0.708 to −0.291) and THBI (
ρ
=−0.524;
P
<0.001; 95% CI −0.704 to −0.282).
Conclusions:
Both THBI and PCCI seem to be valid measures for assessing energy expenditure. Both indexes showed a coherent correlation with the spinal injury level.</description><identifier>ISSN: 1362-4393</identifier><identifier>EISSN: 1476-5624</identifier><identifier>DOI: 10.1038/sc.2014.107</identifier><identifier>PMID: 25000953</identifier><identifier>CODEN: SPCOFM</identifier><language>eng</language><publisher>London: Nature Publishing Group UK</publisher><subject>631/443/319/333/1465 ; 631/443/592 ; 692/699/375/1824 ; 692/700/565/491 ; Adult ; Anatomy ; Biomedical and Life Sciences ; Biomedicine ; Brazil ; Cross-Sectional Studies ; Disability Evaluation ; Energy Metabolism ; Heart Rate - physiology ; Human Physiology ; Humans ; Inpatients ; Male ; Neurochemistry ; Neuropsychology ; Neurosciences ; original-article ; Oxygen Consumption - physiology ; Spinal Cord Injuries - physiopathology ; Wheelchairs</subject><ispartof>Spinal cord, 2014-09, Vol.52 (9), p.677-682</ispartof><rights>International Spinal Cord Society 2014</rights><rights>Copyright Nature Publishing Group Sep 2014</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c424t-b191bcca8c205c130bb613f3efd06e38713da346e19a15e49d85934b53defaac3</citedby><cites>FETCH-LOGICAL-c424t-b191bcca8c205c130bb613f3efd06e38713da346e19a15e49d85934b53defaac3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,776,780,27903,27904</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/25000953$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Coutinho, A CB</creatorcontrib><creatorcontrib>Neto, F R</creatorcontrib><creatorcontrib>Beraldo, P SS</creatorcontrib><title>Validity of heart rate indexes to assess wheeling efficiency in patients with spinal cord injuries</title><title>Spinal cord</title><addtitle>Spinal Cord</addtitle><addtitle>Spinal Cord</addtitle><description>Study design:
