“…16 Higher BSIPs have been associated with higher pressure ulcer incidence rates. 3,17 Thus, high BSIP should be reduced to prevent pressure ulcers. There are some factors that affect the intensity of BSIP, including personal and postural factors, and chair and cushion factors.…”

The effects of phenol neurolysis of the obturator nerve on the distribution of buttock-seat interface pressure in spinal cord injury patients with hip adductor spasticity

Objectives: Hip adductor spasticity may adversely effect shear-force and pressure distribution on the buttocks, where ulcerations most frequently appear in patients with spinal cord injury (SCI). Phenol neurolysis of the obturator nerve (ON) is commonly used to manage hip adductor spasticity. This study aimed to determine the effects on the distribution of buttock-seat interface pressure (BSIP) in a group of SCI patients with adductor spasticity that underwent ON blockade with phenol. Methods: We reviewed the records of SCI patients that were admitted to our clinic between January 2009 and December 2009. BSIP values (obtained with an X-sensor 48) and hip adductor spasticity levels of SCI patients with hip adductor spasticity that underwent ON blockade with phenol were collected. BSIP distributions of the patients were divided into two portions: first one is the BSIP distribution at the pressure p37 mm Hg, and the second one is at the pressure 437 mm Hg. Results: The study included 20 SCI patients (19 males and 1 female), with a mean age of 42.85 ± 13.24 years. Although the percentage of BSIP distribution at p37 mm Hg range increased significantly (Po0.001), after ON neurolysis, BSIP distribution at 437 mm Hg range decreased significantly (Po0.001). In addition, mean hip adductor spasticity decreased significantly after ON neurolysis (Po0.001). Conclusion: Phenol neurolysis of the ON is a promising treatment for the management of hip adductor spasticity in SCI patients and also has positive effects on BSIP, which has a crucial function in the development of pressure ulcers.

“…Those with scores ranging from 19 to 23 are not considered at risk for developing PrUs. 3,25 Interface Pressure: Interface pressure measurements were recorded throughout the surgery using an FSA pressure mapping system (Vista Medical). The FSA pressure mapping system uses paper-thin, flexible force sensors to measure and display interface pressures between 2 surfaces, such as the body and a support surface.…”

“…Since then there have been an increasing number of publications on the prevention and management of pressure ulcers in people who sit for extended periods of time. However, most of these publications did not have any end user collaboration in their development [3,10,11]. In 2016 The TVS commissioned an update of the clinical practice guidelines for seating and pressure ulcers to include the most up to date evidence and practice.…”

a b s t r a c tBackground: Costs for the prevention and management of pressure ulcers have increased significantly with limited published advice from health and social care organisations on seating and preventing pressure ulcers. At the request of the UK Tissue Viability Society the aim of the publication was to develop a practical guide for people, carers and health and social care professionals on how the research and evidence base on pressure ulcer prevention and management can be applied to those who remain seated for extended periods of time. Methods and findings: The evidence base informing the guidelines was obtained by applying a triangulation of methods: a literature review, listening event and stakeholder group consultation. The purpose was to engage users and carers, academics, clinicians, inspectorate and charities, with an interest in seating, positioning and pressure management to: gather views, feedback, stories, and evidence of the current practices in the field to create a greater awareness of the issue. Conclusion:The new guidelines are inclusive of all people with short and long-term mobility issues to include all population groups. The document includes evidence on where pressure ulcers develop when seated, risk factors, best possible seated position and what seat adjustments are required, the ideal seating assessment, interventions, self-help suggestions and key seating outcomes. The updated TVS CPGs have been informed by the best available evidence, the insights and wisdom of experts, stakeholders and people who spend extended periods of time sitting.

A Randomized Control Trial to Evaluate Pressure-Reducing Seat Cushions for Elderly Wheelchair Users

Abstract: A definitive randomized control multicenter cushion trial is feasible with a sample size of 50 to 100 per study group. In the definitive trial, the definition of sitting-acquired pressure ulcers should be limited to lesions occurring over the ischial tuberosities.
