The added value of physiotherapists in preventing pressure injuries in intensive care patients
Physiotherapists improve movement and function for people who experience challenges from aging, injury, illness, or the environment. They promote physical, psychological, emotional and social well-being through prevention, treatment, and rehabilitation (World Physiotherapy, 2023). Intensive care units (ICU) patients frequently struggle with limitations in physical function and activity rendering them at high risk for pressure injuries (PI). The development of PI is augmented by immobility, hypoperfusion, vasopressors, malnutrition, sweating and/or shearing force, whereby the increased pressure on prominent surfaces exceeds the capillary pressure of the underlying tissue resulting in tissue damage and ultimately necrosis (Nieto-GarcĂa et al., 2021; Pickenbrock et al., 2017). This article discusses how physiotherapists with their specific knowledge can add value to prevent, treat or rehabilitate PI in ICU patients (Fig. 1)
Effects of early, combined endurance and resistance training in mechanically ventilated, critically ill patients: a study protocol for a randomised controlled trial.
BACKGROUND
Prolonged need for intensive care is associated with neuromuscular weakness, termed Intensive Care Unit Acquired Weakness. Those affected suffer from severe functional impairment that can persist for years. First studies suggest a positive effect of physiotherapy and early mobilisation. However, the ideal intervention for a preferential functional outcome is not known. So far no randomised controlled trial has been conducted to specifically evaluate an early endurance and resistance training in the mechanically ventilated, critically ill patient.
METHODS/DESIGN
A randomised controlled trial with blinded assessors and 6-month follow-up will be conducted in a tertiary, interdisciplinary intensive care unit in Switzerland. Participants (n = 115; expected dropouts: n = 15) will be randomised to a control group receiving standard physiotherapy and to an experimental group that undergoes early mobilisation combined with endurance and resistance training. The inclusion criteria are being aged 18 years or older, expected mechanical ventilation for more than 72 h and qualitative independence before the illness. Primary endpoints are functional capacity (6-Minute Walk Test) and the ability to perform activities of daily living (Functional Independence Measure) measured at hospital discharge. Secondary endpoints include muscle strength (Medical Research Council sum score, handgrip strength and handheld dynamometry for quadriceps muscle), joint contractures (range of motion), exercise capacity (Timed 'Up & Go' Test) and health-related quality of life (Short Form 36). Safety will be monitored during interventions by indirect calorimetry and continuous intensive care standard monitoring. All previously defined adverse events will be noted. The statistical analysis will be by intention-to-treat with the level of significance set at p < 0.05.
DISCUSSION
This prospective, single-centre, allocation-concealed and assessor-blinded randomised controlled trial will evaluate participant's function after an early endurance and resistance training compared to standard care. Limitations of this study are the heterogeneity of the critically ill and the discontinuity of the protocol after relocation to the ward. The strengths lie in the pragmatic design and the clinical significance of the chosen outcome measures.

Break down barriers - Can point prevalence studies change mobilization practice in the intensive care unit?
Functional ability and quality of life in critical illness survivors with intensive care unit acquired weakness: A secondary analysis of a randomised controlled trial.
INTRODUCTION
Intensive care unit acquired weakness (ICUAW) may contribute to functional disability in ICU survivors, yet performance-based data for general ICU patients are lacking. This study explored functional outcomes of (1) and risk factors for (2) weakness at ICU discharge.
METHODS
Data from a randomised controlled trial that investigated two early exercise regimes in previously independent, ventilated adults (n = 115) without any significant outcome-differences were used for the present analysis. ICUAW was clinically diagnosed in cooperative participants (n = 83) at ICU discharge with the Medical Research Council sum-score (MRC-SS) using a cut-off <48 for moderate or <36 for severe weakness. Primary outcomes were the 6-Minute Walk Test and Functional Independence Measure at hospital discharge. Secondary outcomes included health-related quality of life after six months. Risk factors during the ICU stay were explored for their effect on MRC-SS with linear regression.
RESULTS
Functional outcomes and length of hospital stay significantly differed in patients with severe, moderate to no weakness (6-Minute Walk test: p = 0.013; 110m [IQR 75-240], 196m [90-324.25], 222.5m [129-378.75], Functional Independence Measure: p = 0.001; 91[IQR 68-101], 113[102.5-118.5], 112[97-123], length of stay after ICU discharge: p = 0.008; 20.9d [IQR 15.83-30.73], 16.86d [13.07-27.10], 11.16d [7.35-19.74]). However, after six months participants had similar values for quality of life regardless of their strength at ICU discharge (Short-Form 36 sum-scores physical health: p = 0.874, mental health: p = 0.908). In-bed immobilisation was the most significant factor associated with weakness at ICU discharge in the regression models (MRC-SS: -24.57(95%CI [-37.03 to -12.11]); p<0.001).
CONCLUSIONS
In this general, critically ill cohort, weakness at ICU discharge was associated with short-term functional disability and prolonged hospital length of stay, but not with quality of life, which was equivalent to the values for patients without ICUAW within six months. Immobilisation may be a modifiable risk factor to prevent ICUAW. Prospective trials are needed to validate these results.

Implementing an interprofessional user-centered design approach to develop a bedside leg exercise device
BACKGROUND: Early mobilization is important to improve critically ill patients’ outcomes, but barriers to its implementation are common. A suitable in-bed device to exercise patients’ legs might facilitate early mobilization. OBJECTIVE: The aim of this study was to develop an in-bed leg press that would facilitate early mobilization and enhance strength training of patients in acute care settings. METHODS: A user-centered design approach was applied to develop the device. The process was assessed by different instruments: the system usability scale (SUS) questionnaire, the Kano model questionnaire and interviews with end-users. RESULTS: Through several iterations of a user-centered design process, the prototype of an in-bed leg press was developed and tested. The assessment, based on SUS, Kano and interviews, indicates high usability and demonstrates the advantages of a user-centered design process. CONCLUSIONS: An interprofessional user-centered design approach was successfully implemented to develop a medical device. The early involvement of end-users resulted in a design that already shows a high degree of production readiness. The resulting device fulfilled all core requirements from a therapeutic point of view and included key features related to its practical use
