Pressure Ulcers-A Longstanding Problem: A 7-Year Neurorehabilitation Unit Experience of Management, Care, and Clinical Outcomes

BACKGROUND

Neurological disease patients present an increased risk of developing pressure ulcers. The primary aim of this study is to evaluate the incidence and prevalence of pressure ulcers and their impact on length of stay and functional recovery.

METHODS

A retrospective study was conducted in a neurorehabilitation unit over a seven-year period. Data collected include demographic data, length of stay, functional evaluation, risk of pressure ulcers development, nutritional status, and skin. Pressure ulcers were classified according to the European Pressure Ulcer Advisory Panel System.

RESULTS

Data from 816 patients were analyzed. On admission, the authors found 236 pressure ulcers in 131 patients (about 16%), divided into stage I (25%), stage II (50%), and stage III-IV (25%). The most common sites were the heel (36%) and sacrum (29%). Among the risk factors for the development of pressure ulcers, malnutrition played a significant role, with approximately 76% of patients with pressure ulcers having mild to moderate malnutrition.

CONCLUSION

The presence of pressure ulcers seems to have a negative impact on the functional recovery of patients, as shown by the outcome scales and the average length of stay: 51 days versus 36 days (p < 0.01).

Maximal daily stepping cadence partially explains functional capacity of individuals with end-stage knee osteoarthritis

BACKGROUND

Individuals with end-stage knee osteoarthritis (OA) walk at a lower intensity (ie, slower step cadence) contributing to worse physical function. Previous literature reports daily step counts and sedentary time, with little information regarding stepping bouts or cadence. Determining relationships between daily higher stepping cadence duration and clinical outcomes can move the field toward optimal daily stepping prescription.

OBJECTIVE

To quantify daily physical activity patterns of individuals with end-stage knee OA and determine the contribution of high stepping cadence to explain functional capacity variability.

DESIGN

Cross-sectional analysis.

SETTING

Veterans Administration medical center.

PARTICIPANTS

U.S. military veterans (n = 104; age: 67.1 years [7.2]; mean [SD]; male [89.3%]) with end-stage knee OA were enrolled.

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURE

Functional capacity (6-Minute Walk Test [6MWT]). Physical activity (activPAL wearable sensor; cadence and time sitting, standing, and stepping), pain (Western Ontario and McMaster Universities Osteoarthritis Index-pain subscale) sociodemographic variables, and comorbidities (body mass index and Functional Comorbidity Index) are the main explanatory variables.

RESULTS

Participants' wake time was mainly sitting (11.0 h/day) in ≥60-minute bouts (29.7% ± 12.7 of sitting time). Standing (3.4 hours/day) and stepping (1.4 h/day) primarily occurred in 0-5 minute bouts (standing: 87.7% ± 14.4 of standing time, stepping: 98.7% ± 12.7 of stepping time) and stepping cadence was predominantly incidental (1-19 spm; 52.9% ± 9.6 of total stepping time). Backward elimination model results indicated shorter medium-to-brisk cadence bout duration, older age, and higher pain significantly explained shorter 6MWT distance (Adj R2 =0.24, p < .01).

CONCLUSIONS

Individuals with knee OA spend most of their waking hours sitting, while standing and stepping occurs in short bouts at very low stepping cadence. Decreased time in high stepping cadence is associated with lower functional capacity. Future studies should explore if increasing the daily time spent in higher step cadence can improve functional capacity in this population.

Acute flaccid paralysis of a new surfer: A case report

RATIONALE

Surfer's myelopathy is a rare atraumatic spinal cord injury most frequently experienced by novice surfers. Patients often experience back pain, followed by motor, sensory, bowel, and bladder involvement. Here, we report a case of surfer's myelopathy.

PATIENT CONCERNS

The patient presented with acute low back pain associated with lower limb weakness, sensory loss, urinary retention, and perineal paraesthesia 1 hour after her first surf lesson.

DIAGNOSIS

On arrival at the emergency department, she was noted to have flaccid paralysis with flickers in both lower limbs, reduced sensation in the midthoracic region, reduced anal tone, and saddle anesthesia. Magnetic resonance imaging of the spine revealed evidence of restricted diffusion from T6 to the level of the conus. Extensive investigations, including cerebrospinal fluid analysis, vasculitides/paraneoplastic screening, and further imaging, were unremarkable. She was diagnosed with complete T7 spinal cord injury secondary to surfer's myelopathy.

INTERVENTIONS

She subsequently received methylprednisolone and was transferred to the spinal injury unit for rehabilitation. As she experienced persistent neuropathic pain at the level of the injury, she received input from the local pain team. One month after the injury, the patient developed swelling of the right thigh associated with reduced internal and external rotation of the right hip, impacting rehabilitation. The patient was diagnosed with heterotopic ossification following a triple-phase bone scan. She then received intravenous zolendronic acid, which had a good effect.

OUTCOMES

Four months after the initial presentation, she was discharged to the community. Despite no improvement in her neurological status, she was independent of transfers and mobility with a wheelchair. In addition, she managed her neurogenic bowel and bladder independently with intermittent self-catheterization and a transanal irrigation system. At 6 months, she engaged well with returning to drive program and vocational rehabilitation.

LESSONS

Neurological recovery from surfer's myelopathy has been shown to vary from complete recovery to minimal recovery. With a spinal-specific rehabilitation program, this patient remains independent of her activities of daily living. Surfer's myelopathy often occurs in inexperienced surfers; therefore, it is crucial to provide education to surfers and instructors.

Translation, Reliability and Validity of the Spanish Version of the Modified New Mobility Score (NMS-ES)

The New Mobility Score (NMS) is an easy to administer self-report measure of functional ability, and is used worldwide as a hip fracture (HF) score, but a Spanish version does not exist. The aim of the study is to translate NMS into Spanish, and to measure its inter-rater reliability, internal consistency, and concurrent validity in a sample of Spanish speaking patients with HF. A reliability and validity study with a sample of 60 adults, 65 years or older (46 women and 14 men; mean age 81.7 years) with a hip fracture admitted consecutively to the acute trauma service of the Health Campus Hospital of Granada. The participants were interviewed during the first week after surgery by an occupational therapist or a physiotherapist. The statistical test used for analysis were: Cronbach's α coefficient, McNemar-Bowker test, Bland-Altman plot, Spearman´s Rho, and Mann-Whitney U test. The Cronbach's α coefficient was 0.90. No inter-rater systematic differences were found. We noted significant associations between the Spanish Version of the Modified New Mobility Score (NMS-ES) and selected health outcomes: Age, cognition, pre-fracture function, and basic mobility. The NMS-ES is a reliable and valid instrument to assess pre-injury functional levels for patients with HF in Spanish speaking countries.
