Abstract
Objectives: To investigate the effects of a custom made Lycra trunk orthosis on joint position sense. This was tested on a sample group of 30 healthy BSO students. Ten of these individuals who had the worst joint position sense formed a sub group (poor proprioception group) and their results were analysed separately.Study design: within group experimental design using position matching trials.#Method: subjects were blindfolded and required to reproduce target postures whilst in a ‘kneeling on all fours’ position (3 trials with the orthosis and 3 trials without the orthosis). Photographs were taken of all ‘target’ and ‘estimated target’ postures. These photographs were analysed to obtain ‘repositioning errors’ (in degrees), this was used as a measure of joint position sense acuity. Wilcoxon statistical analysis was used to compare individual mean repositioning error when wearing the orthosis with mean repositioning error when not wearing the orthosis. Additional, subsidiary investigation was carried out to provide insight into subject performance regarding variation with position to be matched and performance over time.Results: Analysis of the whole sample group showed that repositioning errors for the two conditions were very similar, there was no significant difference between mean performance with and without the orthosis. A small improvement in individual mean repositioning error when wearing the orthosis was evident in the poor proprioception group, but this was not statistically significant. Repositioning errors were shown to be significantly smaller with target postures involving the largest amount of spinal extension. Subjects had smaller repositioning errors in their 6th trial as compared to their first trial.Conclusions: the trend of results in the poor proprioception group was in the same direction as in a previous authors study (McNair & Heine, 1999). It is suggested therefore that flexible trunk orthoses do have the potential to improve joint position sense in individuals with existing deficit. Increasing postural awareness in this way may be of benefit to preventing injury. Further research involving individuals with back injury or dysfunction is needed to confirm this suggestion.
