“…The people with a SCI who are active have a higher physical capacity than sedentary people with a SCI. 2 Furthermore, being physically active and fit appears to be associated with several health benefits in persons with SCI. 3 Therefore, it is important to promote a physically active lifestyle in people with SCI to prevent secondary complications.…”

Study design: Cross-sectional study. Objectives: To evaluate the physical activity scale for individuals with physical disabilities (PASIPD) in people with spinal cord injury (SCI). Setting: Eight Dutch rehabilitation centers with a specialized SCI unit. Methods: The PASIPD was examined by comparing group scores of people with different personal (age, gender and body mass index) and lesion characteristics (level (paraplegia/tetraplegia), completeness, time since injury (TSI)) in 139 persons with SCI 1 year after discharge from in-patient rehabilitation. Relationships between PASIPD scores and measures of activities (wheelchair skills, Utrecht Activity List, mobility range and social behavior subscales of the SIP68) and fitness (peak oxygen uptake, peak power output and muscular strength) were determined. Results: Persons with tetraplegia had significantly lower PASIPD scores than those with paraplegia (Po0.02). Persons with longer TSI had lower PASIPD scores than persons with shorter TSI (Po0.03). PASIPD scores showed moderate correlations with activities (0.36-0.51, Po0.01) and weak-tomoderate correlations with fitness parameters (0.25-0.36, Po0.05). Conclusion: In a fairly homogeneous group of persons with SCI, 1 year after in-patient rehabilitation, the PASIPD showed weak-to-moderate relationships with activity and fitness parameters. There seems to be a limited association between self-reported activity level and fitness in people with SCI.

“…2,3 A low level of physical capacity is associated with a decrease in activity, 3,4 functional status 5,6 and participation. 2,7 This may result in the vicious circle of decreased physical capacity leading to decreased activity and participation, which further reduces physical capacity, and so on. Furthermore, a low level of physical capacity is associated with a high risk of medical (cardiovascular) complications.…”

“…6,10,11 Hence, the evaluation of physical capacity can give an indication of the potential level of activity, participation and quality of life. 2,6,7 Clinicians and rehabilitation researchers need comparative values for different components of physical capacity (ie peak oxygen uptake, peak power output, muscle strength of the upper extremity and respiratory function). 3 This will help them to set targets in SCI rehabilitation.…”

Physical capacity in wheelchair-dependent persons with a spinal cord injury: a critical review of the literature

Study design: Review of publications. Objective: To assess the level of physical capacity (peak oxygen uptake, peak power output, muscle strength of the upper extremity and respiratory function) in wheelchair-dependent persons with a spinal cord injury (SCI). Setting: Erasmus MC, University Medical Centre Rotterdam, The Netherlands. Methods: Pubmed (Medline) search of publications from 1980 onwards. Studies were systematically assessed. Weighted means were calculated for baseline values. Results: In tetraplegia, the weighted mean for peak oxygen uptake was 0.89 l/min for the wheelchair exercise test (WCE) and 0.87 l/min for arm-cranking or hand-cycling (ACE). The peak power output was 26 W (WCE) and 40 W (ACE). In paraplegia, the peak oxygen uptake was 2.10 l/min (WCE) and 1.51 l/min (ACE), whereas the peak power output was 74 W (ACE) and 85 W (WCE). In paraplegia, muscle strength of the upper extremity and respiratory function were comparable to that in the able-bodied population. In tetraplegia muscle strength varied greatly, and respiratory function was reduced to 55-59% of the predicted values for an age-, gender-and height-matched able-bodied population. Conclusions: Physical capacity is reduced and varies in SCI. The variation between results is caused by population and methodological differences. Standardized measurement of physical capacity is needed to further develop comparative values for clinical practice and rehabilitation research.

“…Previous studies 3,[10][11][12] assessed predictors of physical capacity, but had methodologic limitations. Most were crosssectional or combinations of cross-sectional and longitudinal associations and were, therefore, not strictly predictive.…”

“…Unfortunately, most known determinants of physical capacity-such as age, sex, and level of the lesion-can be considered, but are not changeable. 11,12 Some modifiable aspects of lifestyle (eg, smoking or alcohol use) and management (eg, stabilization of the spine) have been associated with physical capacity 7,10,[20][21][22][23] ; however, causality cannot be established from the available cross-sectional data for subjects with SCI. If it could be demonstrated that giving up smoking, increasing participation in work and/or sports activities, moderating alcohol or dietary intake, and stabilizing the spine (by surgical fixation or by wearing a halo or corset) predict a favorable outcome, we might have means to enhance physical capacity during an early phase of recovery.…”

ABSTRACT. Haisma JA, van der Woude LH, Stam HJ, Bergen MP, Sluis TA, de Groot S, Dallmeijer AJ, Bussmann JB. Prognostic models for physical capacity at discharge and 1 year postdischarge from rehabilitation in persons with spinal cord injury. Arch Phys Med Rehabil 2007;88:1694-703.Objective: To develop prognostic models for physical capacity at discharge and 1 year after discharge from inpatient rehabilitation in persons with spinal cord injury (SCI).Design: Inception cohort; data collected at start of rehabilitation (nϭ104), at discharge (nϭ81), and 1 year later (nϭ74).Setting: Eight Dutch rehabilitation centers. Participants:Patients with SCI at initial rehabilitation.Interventions: Not applicable. Main Outcome Measures: Physical capacity determined by endurance capacity (peak oxygen uptake [VO 2 peak, in L/min] and power output [POpeak, in watts]) during a maximal exercise test, arm muscle strength, and respiratory function. Multiple regression models, either with or without prior outcome, evaluated subject, lifestyle, and lesion-related predictors.Results: Only start VO 2 peak contributed to the prediction of discharge VO 2 peak (R 2 ϭ.51). Discharge VO 2 peak contributed to its prediction 1 year later (R 2 ϭ.75). Start POpeak, sex, age, and level of lesion contributed to discharge POpeak (R 2 ϭ.73). Discharge POpeak, hours of employment before injury, and level of lesion contributed to POpeak 1 year later (R 2 ϭ.81). Models without prior outcome explained less variance. Education, employment, body mass index, not smoking, and conservative stabilization of the spine positively contributed to endurance capacity. Muscle strength was well predicted (R 2 range, .68Ϫ.84). Without prior outcome, respiratory function was poorly predicted.Conclusions: Because prior outcome contributed to an accurate prediction, the early assessment of physical capacity is important in establishing prognoses. Although their accuracy warrants caution in their application, models could complement clinical expertise when informing patients about expected physical outcome and identifying those at risk of low physical capacity.
