Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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
A new model of care for stroke rehabilitation, using mechanobiology-based, robot-assisted weight-bearing exercise with biofeedback to improve bone health in patients following an acute stroke
a) Robot-assisted exercise: The robot can provide physical support of lower limbs during sit-to-stand and stand-to-sit transfers. With waist, knees and feet firmly fastened and protected, the patients can perform sit-to-stand exercise.

b) During sit-to-stand exercise, the biofeedback device compares the foot reaction force with two preset thresholds and emits audible feedback tones to guide the patient in maintaining certain speed of sit-to-stand which results in the load within the predicted lower threshold and upper threshold

c) & d) Robot-assisted weight-bearing exercise commenced within one month of stroke for a period of 12 months (three training sessions weekly for the first three months and one training session weekly for the remaining 9 months). Each sit-to-stand training session lasts up to 60 mins with a minimum of 6 sets (15 repetitions per set with 3 mins rest between sets)

e) The mode of administration: group of 4

f) Supervision: physiotherapist & research assistant

g) At the time point of three month, the feasibility and safety of the intervention will be assessed.

h) Monitor adherence to the intervention: attendance check lists and reminder text messages

Summary
Brief summary
The purpose of this partnership project is to address a significant evidence-to-practice gap by implementing and evaluating a new model of care for stroke rehabilitation, using mechanobiology-based, robot-assisted weight-bearing exercise with biofeedback to improve bone health in patients following an acute stroke.

Hypothesis:: Relative to standard care, the new model of care for stroke patients utilising a mechanobiology-based robot-assisted weight-bearing exercise will achieve significant and sustainable improvements in bone health consistent with that recommended by the 2017 clinical guidelines for stroke management.

This project will provide the necessary comparative-effectiveness ‘proof-of-concept’ evidence for the use of robots in clinical practice to inform rehabilitation policy.
