Abstract

Purpose: The purpose of this study was to investigate the potential functional improvement of the spastic-paretic upper extremity of individuals with chronic hemiparesis when using a dynamic wrist-hand orthosis with and without concurrent botulinum toxin type-A (BoNTA) injections into the spastic upper extremity muscles. Methods: A three-year retrospective chart review was conducted on all stroke patients referred to out-patient occupational therapy for an upper extremity rehabilitation program, which included use of a dynamic wrist-hand orthosis (DWHO). Three charts documented concurrent treatment with a DWHO + BoNTA. Eleven charts documented DWHO use without concurrent BoNTA treatment. Pre- and post-intervention outcome measure scores were compared between the two groups. Pre- and post-interven- tion scores were also analyzed irrespective of treatment group. Results: Although improvement approached significance on three of the documented outcome measures when comparing the DWHO + BoNTA and DWHO groups, no statistically significant changes were found. A significant difference (p < 0.05) however, was found between the pre- and post-intervention scores irrespective of treatment group in 13 of 14 of the outcome measures documented. Conclusions: Further research with a larger sample size is suggested to assess the combined effect of using a dynamic wrist-hand orthosis and BoNTA injections into the spastic upper extremity muscles of individuals with chronic hemiparesis post stroke.
