Intensive physiotherapy for vegetative and minimally conscious state patients: a retrospective audit and analysis of therapy intervention

Operationalising routinely collected patient data in research to further the pursuit of social justice and health equity: a team-based scoping review

BACKGROUND

Vast volumes of routinely collected data (RCD) about patients are collated by health professionals. Leveraging this data - a form of real-world data - can be valuable for quality improvement and contributing to the evidence-base to inform practice. Examining routine data may be especially useful for examining issues related to social justice such as health inequities. However, little is known about the extent to which RCD is utilised in health fields and published for wider dissemination.

OBJECTIVES

The objective of this scoping review is to document the peer-reviewed published research in allied health fields which utilise RCD and evaluate the extent to which these studies have addressed issues pertaining to social justice.

METHODS

An enhanced version of the Arksey and O'Malley's framework, put forth by Westphalm et al. guided the scoping review. A comprehensive literature search of three databases identified 1584 articles. Application of inclusion and exclusion criteria was piloted on 5% of the papers by three researchers. All titles and abstracts were screened independently by 2 team members, as were full texts. A data charting framework, developed to address the research questions, was piloted by three researchers with data extraction being completed by the lead researcher. A sample of papers were independently charted by a second researcher for reliability checking.

RESULTS

One hundred and ninety papers were included in the review. The literature was diverse in terms of the professions that were represented: physiotherapy (33.7%) and psychology/mental health professions (15.8%) predominated. Many studies were first authored by clinicians (44.2%), often with clinical-academic teams. Some (33.25%) directly referenced the use of their studies to examine translation of research to practice. Few studies (14.2%) specifically tackled issues pertaining to social justice, though many collected variables that could have been utilised for this purpose.

CONCLUSION

Studies operationalising RCD can meaningfully address research to practice gaps and provide new evidence about issues related to social justice. However, RCD is underutilised for these purposes. Given that vast volumes of relevant data are routinely collected, more needs to be done to leverage it, which would be supported by greater acknowledgement of the value of RCD studies.

Assistive technologies, including orthotic devices, for the management of contractures in adults after a stroke

BACKGROUND

Contractures (reduced range of motion and increased stiffness of a joint) are a frequent complication of stroke. Contractures can interfere with function and cause cosmetic and hygiene problems. Preventing and managing contractures might improve rehabilitation and recovery after stroke.

OBJECTIVES

To assess the effects of assistive technologies for the management of contractures in adults after a stroke.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, five other databases, and three trials registers in May 2022. We also searched for reference lists of relevant studies, contacted experts in the field, and ran forward citation searches.

SELECTION CRITERIA

Randomised controlled studies (RCTs) that used electrical, mechanical, or electromechanical devices to manage contractures in adults with stroke were eligible for inclusion in this review. We planned to include studies that compared assistive technologies against no treatment, routine therapy, or another assistive technology.

DATA COLLECTION AND ANALYSIS

Three review authors (working in pairs) selected all studies, extracted data, and assessed risk of bias. The primary outcomes were passive joint range of motion (PROM) with and without standardised force, and indirect measures of PROM. The secondary outcomes included hygiene. We also wanted to evaluate the adverse effects of assistive technology. Effects were expressed as mean differences (MDs) or standardised mean differences (SMDs) with 95% confidence intervals (CIs).

MAIN RESULTS

Seven studies fulfilled the inclusion criteria. Five of these were meta-analysed; they included 252 adults treated in acute and subacute rehabilitation settings. All studies compared assistive technology with routine therapy; one study also compared assistive technology with no treatment, but we were unable to obtain separate data for stroke participants. The assistive technologies used in the studies were electrical stimulation, splinting, positioning using a hinged board, and active repetitive motor training using a non-robotic device with electrical stimulation. Only one study applied stretching to end range. Treatment duration ranged from four to 12 weeks. The overall risk of bias was high for all studies. We are uncertain whether: • electrical stimulation to wrist extensors improves passive range of wrist extension (MD -7.30°, 95% CI -18.26° to 3.66°; 1 study, 81 participants; very low-certainty evidence); • a non-robotic device with electrical stimulation to shoulder flexors improves passive range of shoulder flexion (MD -9.00°, 95% CI -25.71° to 7.71°; 1 study; 50 participants; very low-certainty evidence); • assistive technology improves passive range of wrist extension with standardised force (SMD -0.05, 95% CI -0.39 to 0.29; four studies, 145 participants; very low-certainty evidence): • a non-robotic device with electrical stimulation to elbow extensors improves passive range of elbow extension (MD 0.41°, 95% CI -0.15° to 0.97°; 1 study, 50 participants; very low-certainty evidence). One study reported the adverse outcome of pain when using a hinged board to apply stretch to wrist and finger flexors, and another study reported skin breakdown when using a thumb splint. No studies reported hygiene or indirect measures of PROM.

AUTHORS' CONCLUSIONS

Only seven small RCTs met the eligibility criteria of this review, and all provided very low-certainty evidence. Consequently, we cannot draw firm conclusions on the effects of assistive technology compared with routine therapy or no therapy. It was also difficult to confirm whether there is a risk of harm associated with treatment using assistive technology. Future studies should apply adequate treatment intensity (i.e. magnitude and the duration of stretch) and use valid and reliable outcome measures. Such studies might better identify the role of assistive technology in the management of contractures in adults after a stroke.

Translation and Transcultural Adaptation of the Wessex Head Injury Matrix, Italian Version: A Preliminary Report

Background: Patients who are in a coma, a vegetative state or a minimally conscious state present a clinical challenge for neurological assessment, which is a prerequisite for establishing a prognosis and planning management. Several scales have been developed to evaluate these patients. The Wessex Head Injury Matrix is a comprehensive tool but is currently available only in the French and English languages. The aim of this study was to translate and evaluate the reliability of the Italian version of the scale. Methods: The original scale was translated according to a standard protocol: three separate translations were made, and a selected version was back-translated to check for any errors in order to obtain the most accurate Italian translation. A final back translation of the agreed version was made as a further check. The final version was then administered blind to a consecutive series of patients with severe acquired brain injury by two examiners. Inter-rater and test-retest reliability were assessed using a weighted Cohen’s kappa (Kw). Concurrent validity of the WHIM was evaluated by ρ Spearman’s correlation coefficient using the Glasgow Coma Scale (GCS) and the Coma Recovery Scale Revised (CRS-R) as the available gold standard. Results: Twenty-four patients (12 males and 12 females; mean age 59.9 ± 20.1; mean duration from index event 17.7 ± 20.0 days) with stroke (n = 15), traumatic brain injury (n = 7) and anoxic encephalopathy (n = 2) were included. Inter-rater [Kw 0.80 (95% CI 0.75–0.84)] and test-retest reliability [Kw 0.77 (95% CI 0.72–0.81)] showed good values. WHIM total scores correlated significantly with total scores on the GCS (ρ = 0.776; p < 0.001) and the CRS-R (ρ = 0.881; p < 0.001) demonstrating concurrent validity; Conclusion: The Italian version of the scale is now available for clinical practice and research.

Effect of Rehabilitation Treatments on Disability in Persons With Disorders of Consciousness: A Propensity Score Study

OBJECTIVE

To evaluate the effects of rehabilitation (physical and cognitive) treatments on the diagnosis severity and Disability Rating Scale (DRS) scores, adjusted for a number of potential confounders measured at baseline, in a large cohort of patients with disorders of consciousness across time.

DESIGN AND SETTING

An observational, longitudinal (2 evaluations), multicenter project was made in 90 Italian centers.

PARTICIPANTS

Patients (N=364) with a diagnosis of disorders of consciousness.

MAIN OUTCOME MEASURES

Primary outcome was the severity of diagnosis, expressed on an ordinal scale (Other<MCS<VS<death). In the Other group were included patients who emerged from an MCS and recovered consciousness. The secondary outcome was the DRS score (range of 0-30 with 30 being the worst value). The DRS is a tool used to define the level of residual disability, commonly used to classify the level of functional impairment in patients with acquired brain injury. Both outcomes were measured for each wave.

RESULTS

A total of 364 subjects having a complete set of demographic, clinical, and pharmacologic data were included in the propensity score (PS) analysis. Results showed that the rehabilitation treatments (physical and cognitive) reduced the clinical worsening over time in both severity diagnosis and DRS (around 6.5 points) in patients with disorders of consciousness across different propensity score strategies (ie, PS matching, PS adjustment, and PS-weighted procedures). In addition, cognitive protocols seem to be limited to patients with a median value of DRS=23.

CONCLUSIONS

Our propensity score analysis suggests that rehabilitation treatment protocols seem effective and should be applied to a broader spectrum of patients with disorders of consciousness.

Effects on the diagnosis change and on the disability level for individuals with disorder of consciousness: which predictors?

Prediction of the functional recovery in patients with disorders of consciousness (DOC) is still complex because of the different numbers of variables that influence the possibility of observing changes in clinical outcome. The aim of the present study is to identify the best set of predictors of the change in DOC diagnosis among different pharmacotherapy and nonpharmacotherapy indicators. This study analyzed data collected in a longitudinal, two-evaluation, multicenter project conducted in 90 centers. We analyzed the predictor effects of physical and cognitive treatments, duration of disease, etiology, age, and sex (nonpharmacological treatments) as well as the use of antiparkinson, psycholeptic, psychoanaleptic, and muscle-relaxant drugs (pharmacological variables). Ordered logistic models, linear regression models with bootstrap estimation, and model averaging procedures were used. The results showed that physical and cognitive treatments [best predictor: odds ratio (OR)=413.3, P<0.001], age (OR=0.964, P<0.001), and use of psycholeptic drugs (negative effect: OR=0.373, P=0.039) were the variables that contributed in general toward a change in diagnosis. Notably, the use of psycholeptic drugs seemed to impede the functional recovery in patients with DOC, so serious reflections on its use will be made.

Is digital photography an accurate and precise method for measuring range of motion of the hip and knee?

BACKGROUND

Accurate measurements of knee and hip motion are required for management of musculoskeletal pathology. The purpose of this investigation was to compare three techniques for measuring motion at the hip and knee. The authors hypothesized that digital photography would be equivalent in accuracy and show higher precision compared to the other two techniques.

METHODS

Using infrared motion capture analysis as the reference standard, hip flexion/abduction/internal rotation/external rotation and knee flexion/extension were measured using visual estimation, goniometry, and photography on 10 fresh frozen cadavers. These measurements were performed by three physical therapists and three orthopaedic surgeons. Accuracy was defined by the difference from the reference standard, while precision was defined by the proportion of measurements within either 5° or 10°. Analysis of variance (ANOVA), t-tests, and chi-squared tests were used.

RESULTS

Although two statistically significant differences were found in measurement accuracy between the three techniques, neither of these differences met clinical significance (difference of 1.4° for hip abduction and 1.7° for the knee extension). Precision of measurements was significantly higher for digital photography than: (i) visual estimation for hip abduction and knee extension, and (ii) goniometry for knee extension only.

CONCLUSIONS

There was no clinically significant difference in measurement accuracy between the three techniques for hip and knee motion. Digital photography only showed higher precision for two joint motions (hip abduction and knee extension). Overall digital photography shows equivalent accuracy and near-equivalent precision to visual estimation and goniometry.

Physiotherapy for vegetative and minimally conscious state patients: family perceptions and experiences

PURPOSE

To examine family perceptions of physiotherapy provided to relatives in vegetative or minimally conscious states.

METHOD

Secondary thematic analysis of 65 in-depth narrative interviews with family members of people in vegetative or minimally conscious states.

RESULTS

Families place great significance on physiotherapy in relation to six dimensions: "Caring for the person", "Maximising comfort", "Helping maintain health/life", "Facilitating progress", "Identifying or stimulating consciousness" and "Indicating potential for meaningful recovery". They can have high expectations of what physiotherapy may deliver but also, at times, express concerns about physiotherapy's potential to cause pain or distress, or even constitute a form of torture if they believe there is no hope for "meaningful" recovery.

CONCLUSION

Physiotherapists can make an important contribution to supporting this patient group and their families but it is vital to recognise that family understandings of physiotherapy may differ significantly from those of physiotherapists. Both the delivery and the withdrawal of physiotherapy is highly symbolic and can convey (inadvertent) messages to people about their relative's current and future state. A genuine two-way dialogue between practitioners and families about the aims of physiotherapeutic interventions, potential outcomes and patients' best interests is critical to providing a good service and establishing positive relationships and appropriate treatment.

IMPLICATIONS FOR REHABILITATION

Families of people in PVS or MCS consider physiotherapy as a vital part of good care. Clear communication is critical if therapeutic input is withdrawn or reduced. The purpose of physiotherapy interventions can be misinterpreted by family members. Physiotherapists need to clarify what physiotherapy can, and cannot, achieve. Families can find some interventions distressing to witness--explaining to families what interventions involve, what they can expect to see (and hear) may be helpful. Physiotherapists and families can attribute different meanings to physiotherapy. Physiotherapists need to identify how families view interventions and modify their explanations accordingly to enhance information sharing.
