OBJECTIVE: The aim of this study was to compare the effects of two kinds of wrist-hand orthosis on wrist flexor spasticity in chronic stroke patients.
DESIGN: This is a randomized controlled trial.
SETTING: The study was conducted in a rehabilitation center.
PARTICIPANTS: A total of 40 chronic hemiparetic stroke patients with wrist flexor spasticity were involved in the study.
INTERVENTIONS: Patients were randomly assigned to either an experimental group (conventional rehabilitation therapy + 3D-printed orthosis, 20 patients) or a control group (conventional rehabilitation therapy + low-temperature thermoplastic plate orthosis, 20 patients). The time of wearing orthosis was about 4-8 hours per day for six weeks.
MAIN MEASURES: Primary outcome measure: Modified Ashworth Scale was assessed three times (at baseline, three weeks, and six weeks). Secondary outcome measures: passive range of motion, Fugl-Meyer Assessment score, visual analogue scale score, and the swelling score were assessed twice (at baseline and six weeks). The subjective feeling score was assessed at six weeks.
RESULTS: No significant difference was found between the two groups in the change of Modified Ashworth Scale scores at three weeks (15% versus 25%, P = 0.496). At six weeks, the Modified Ashworth Scale scores (65% versus 30%, P = 0.02), passive range of wrist extension (P < 0.001), ulnar deviation (P = 0.028), Fugl-Meyer Assessment scores (P < 0.001), and swelling scores (P < 0.001) showed significant changes between the experimental group and the control group. No significant difference was found between the two groups in the change of visual analogue scale scores (P = 0.637) and the subjective feeling scores (P = 0.243).
CONCLUSION: 3D-printed orthosis showed greater changes than low-temperature thermoplastic plate orthosis in reducing spasticity and swelling, improving motor function of the wrist and passive range of wrist extension for stroke patients.
