Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants in the splinting and electrical stimulation group will receive a 4-week programme of an hour electrical stimulation to wrist and finger extensors plus 12 hours of hand splinting per day, 5-7 days a week. Customised hand splints will be used. The splints will be worn during electrical stimulation and generally at night. However, splinting time may need to be varied to minimise interference with hygiene and therapy. Wrists will be stretched to maximum tolerable extension while in a splint. Electrical stimulation will be applied using the Neuro Trac Sports simulation unit at a frequency of 50hz. The amplitude of stimulation will be set at a level to achieve maximum tolerable contractions.

Comparator / control treatment
Participants in the splinting alone group will receive hand splinting 12 hours a day, 5 -7 days a week, over a 4-week period. Customised hand splints will be used. The splints will be worn generally at night. However, splinting time may need to be varied to minimise interference with hygiene and therapy. Wrists will be stretched to maximum tolerable extension while in a splint.

Outcomes
Primary outcome [1] 5340 0
Extensibility of the extrinsic wrist and finger flexor muscles. This will be determined by measuring the passive wrist extension range at a torque of 3Nm with fingers in full extension.
Timepoint [1] 5340 0
At baseline, at the end of the 4-week intervention period (i.e., post-intervention) and 2 weeks later (i.e., follow-up).
Secondary outcome [1] 8972 0
Spasticity will be rated using the Tardieu Scale.
Timepoint [1] 8972 0
At baseline, at the end of the 4-week intervention period (i.e., post-intervention) and 2 weeks later (i.e., follow-up).
Secondary outcome [2] 8973 0
Strength of wrist extensors will be determined with a dynamometer.
Timepoint [2] 8973 0
At the end of the 4-week intervention period (i.e., post-intervention) and 2 weeks later (i.e., follow-up).
Secondary outcome [3] 242080 0
Motor control will be assessed using the hand movement item of the Motor Assessment Scale.
Timepoint [3] 242080 0
At the end of the 4-week intervention period (i.e., post-intervention) and 2 weeks later (i.e., follow-up).
Secondary outcome [4] 242081 0

At baseline, at the end of the 4-week intervention period (i.e., post-intervention) and 2 weeks later (i.e., follow-up).
Secondary outcome [7] 242085 0
Extensibility of the extrinsic wrist and finger flexor muscles. This will be determined by measuring the passive wrist extension range at a torque of 2Nm with fingers in full extension.

Eligibility
Key inclusion criteria

-inpatient rehabilitation stay anticipated to be of at least 4 weeks
-ability to participate in a splinting regimen and an electrical stimulation programme
-passive wrist extension to at least neutral with fingers extended (ie. able to place the hand with wrist in neutral and fingers extended on a flat surface)
-informed consent from the participants or their person responsible
Minimum age
16 Years
Maximum age
85 Years
Sex

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants who fit the eligibility criteria or the persons responsible for them will be given the Participant Information Sheets. An investigator will explain the study protocol to them. No pressure to participate will be placed on them under any circumstances. They will be informed that participation in the study is entirely voluntary and they are free to withdraw from the study at any stage without any effect on their current and future treatment. Those who agree to participate will be given the Consent Forms to sign and participate in the study. After completion of the baseline assessment, participants will be randomly allocated to one of the two groups: splinting and electrical stimulation (experimental) and splinting only (control). The allocation sequence is computer generated by a person not involved in recruitment and concealed using consecutively numbered, sealed and opaque envelopes. The envelopes will be kept off-site in a centralised registry and only opened by a person not involved in the study after the participants have completed the baseline assessment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The allocation sequence is computer generated by a person not involved in the recruitment.
