Predictive Factors for Physiotherapy Session Length at an Adult Intensive Care Unit: A Longitudinal Panel Study.

OBJECTIVE: To identify predictive factors for the length of physiotherapy sessions for adult intensive care unit (ICU) patients. DESIGN: Longitudinal panel study. SETTING: ICU of a secondary-care public teaching hospital, the University Hospital at the University of Sao Paulo, Brazil. PARTICIPANTS: Medical and surgical patients who received physiotherapy (N=181) assessed in 339 physiotherapy sessions. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The study investigator followed physiotherapists during their work shift and timed the physiotherapy session's length with a stopwatch. The association between session length and patient, physiotherapist, and service-related factors was evaluated by a mixed model. RESULTS: Assessed in this study were 339 physiotherapy sessions during 79 periods of observation that involved 181 patients and 19 physiotherapists. Median session length was 29 (interquartile range: 22.6-38.9) minutes; median number of patients assisted per physiotherapist per 6-hour shift was 5 (4-5). Physiotherapist's median age was 35 (26-39) years old, and median ICU experience was 13.0 (0.4-16.0) years. Patients were mostly older adults who were post surgery and had been at the ICU for 5 (2-9) days. Factors associated with physiotherapy session length (min) were the following: performing both motor- and respiratory-related physiotherapy procedures during the session (ß=6.5; 95% confidence interval [CI], 3.8-9.2), altered chest x-ray (ß=2.8; 95% CI, 0.3-5.3), ICU mobility scale (IMS) (ß=1.2; 95% CI, 0.4-2.0), contraindication to any level of out-of-bed mobilization (ß=-6.9; 95% CI, -10.5 to -3.3), afternoon shift (ß=-4.0; 95% CI, -6.7 to -1.4), and Barthel index (ß=-0.2; 95% CI, -0.3 to -0.1). CONCLUSIONS: The factors associated with longer session lengths were performing both motor- and respiratory-related physiotherapy procedures during the session, altered chest x-ray, and the IMS. Contraindication to any level of out-of-bed mobilization and sessions performed during the afternoon shift (vs the morning shift) were associated with shorter session lengths.

Physical activity, muscle strength, and exercise capacity 3 months after severe sepsis and septic shock.

PURPOSE: To quantify the physical activity in daily life (PADL), muscle strength, and exercise capacity in the short and medium term in survivors of severe sepsis and septic shock. METHODS: Prospective cohort study with a follow-up from hospital admission to 3 months after hospital discharge. Seventy-two patients admitted to the ICU for severe sepsis or septic shock and a control group of healthy sedentary subjects (n = 50) were enrolled. All patients had their PADL quantified by an accelerometer during their hospital stay and 3 months after. Exercise capacity and handgrip and quadriceps muscle strength were also evaluated. RESULTS: During hospitalization, patients spent the majority of their time inactive in a lying or sitting position (90 ± 34% of daily time). Physical inactivity was partially reduced 3 months after (58 ± 20% of daily time). However, the time patients spent walking was only 63% of the time reported for healthy subjects. Patients also showed lower movement intensity when compared with controls (2.1 ± 0.3 vs 2.5 ± 0.4 m/s(2)). At hospital discharge, muscle strength and exercise capacity were approximately 54% of the predicted value, and these parameters showed significant increase in patients 3 months after (70% of predicted value). Multivariable analysis demonstrated that the use of systemic corticosteroids and hospitalization time negatively influenced quadriceps strength and exercise capacity at the time of hospital discharge. CONCLUSION: Our results suggest that survivors of sepsis admitted to the ICU have a substantial reduction in physical activity, exercise capacity, and muscle strength compared to healthy subjects that persist even 3 months after hospital discharge.

Reliability of photogrammetry in the evaluation of the postural aspects of individuals with structural scoliosis.

PURPOSE: The purpose of this study was to investigate the reliability of photogrammetry in the measurement of the postural deviations in individuals with idiopathic scoliosis. METHODS: Twenty participants with scoliosis (17 women and three men), with a mean age of 23.1 ± 9 yrs, were photographed from the posterior and lateral views. The postural aspects were measured with CorelDRAW software. RESULTS: High inter-rater and test-retest reliability indices were found. It was observed that with more severity of scoliosis, greater were the variations between the thoracic kyphosis and lumbar lordosis measures obtained by the same examiner from the left lateral view photographs. A greater body mass index (BMI) was associated with greater variability of the trunk rotation measures obtained by two independent examiners from the right, lateral view (r = 0.656; p = 0.002). The severity of scoliosis was also associated with greater inter-rater variability measures of trunk rotation obtained from the left, lateral view (r = 0.483; p = 0.036). CONCLUSIONS: Photogrammetry demonstrated to be a reliable method for the measurement of postural deviations from the posterior and lateral views of individuals with idiopathic scoliosis and could be complementarily employed for the assessment procedures, which could reduce the number of X-rays used for the follow-up assessments of these individuals.
