Abstract: Custom special seating system aims to achieve position for function and pressure relief for comfort. The current trend of healthcare delivery is evidence-based and outcome measures are important instruments towards this goal. This study was the first systematic outcome measure on custom special seating in Hong Kong. Both objective and subjective outcome measure instruments were used to evaluate the special seating service provided by the Spastics Association of Hong Kong Jockey Club Rehabilitation Seating Centre. Seated Postural Control Measure (SPCM) was used as an objective outcome measure in evaluating body alignment and functional tasks performance before and after the provision of custom seating. The SPCM uses a 7-point scale across 22 items of alignment and 12 items of function. Quebec User Evaluation of Satisfaction with assistive Technology (QUEST) allows users to evaluate satisfaction (5-point scale) on both device and service (12 items) as well as rating of the importance of the items. QUEST was done using a one-to-one semi-structured interview. Since most users of special seating service in Hong Kong do not understand English, a Chinese version of QUEST was developed. Twenty-eight subjects (18 males, 10 females, mean age = 35) participated in the SPCM and 18 of them had the intelligence to complete the QUEST. The SPCM revealed the provision of custom special seating did significantly improve both body alignment and functional tasks performance. A greater amount of improvement was observed in alignment than that in performance. However, there was no correlation between the improvements in body alignment with that in performance. Users were generally satisfied with the service provided by the Centre. Of the eight device related items in QUEST, 'Comfort' was the most common item while 'Weight' was the least common item that the end-users rated as important in terms of satisfaction. Of the four service related items in QUEST, 'Service Delivery' was the item that scored the lowest. Part of the reason was the long product delivery time. There was no correlation between user satisfaction on device and service. This study failed to find any correlation between subjective and objective outcome measures of the special seating service provided by the Centre. In other words, user satisfaction was unrelated to body alignment and functional tasks performance as evaluated by special seating professionals.
