About this study
Official title: Actimeric Monitoring of the Use of the Paretic Upper Limb in the Activities of Daily Living of the Post-chronic Stroke Subject in a Home Environment
After a stroke, 80% of patients continue to have difficulty using their paretic upper limb in activities of daily living (ADL) despite post-stroke rehabilitation practices that aim to promote the use of the paretic upper limb. It is known that functional recovery depends on actual use (Use it or Loose it), but one-time measurements in the clinic do not allow quantification of the actual use of the paretic upper limb in daily life (in the person's living environment).
The investigators hypothesize the feasibility of quantifying functional use of the paretic upper limb by actimetry in clinical routine.

After a stroke, 80% of patients continue to have difficulty using their paretic upper limb in activities of daily living (ADL) despite post-stroke rehabilitation practices that aim to promote the use of the paretic upper limb. It is known that functional recovery depends on actual use (Use it or Loose it), but one-time measurements in the clinic do not allow quantification of the actual use of the paretic upper limb in daily life (in the person's living environment).
Project will monitor 30 chronic and 30 healthy subjects over one week period using two wrist worn sensors .
The main objective is to objectively quantify by actimetry, over 7 days, the real functional use of the paretic upper limb in the activities of daily living of post-stroke hemiparetic subjects in chronic phase, by the functional use ratio between the two arms (UseRatio).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Wearing bracelets (3-Axis Logging Accelerometer)Device
Participants will be required to wear wristbands containing an accelerometer on each wrist. The bracelets will be kept on both wrists for 7 days with permission to remove them from time to time.
| Study group | Role | What they receive |
|---|---|---|
| Hemiparetic post-stroke subjects | Experimental | Stroke patients with motor sequelae in the upper limb. Receives: Device: Wearing bracelets (3-Axis Logging Accelerometer) |
| Healthy subjects | Other | Subjects without stroke. Receives: Device: Wearing bracelets (3-Axis Logging Accelerometer) |
What is being measured
The primary outcome is the main question the study is designed to answer.
FuncUseRatio
The paretic functional use score is a ratio of functional movements performed by the paretic upper limb to the sum of functional movements performed by the paretic and non-paretic upper limbs (in percentage %).
Measured: 7 days
Secondary outcomes (5)
Use
Measurement of the amount of functional movement of each upper limb, in an ecological situation during activities of daily living of post-stroke and healthy subjects.
Measured: 7 days
Intensity
Measurement of the intensity of movements (functional and non-functional) of each upper limb, in an ecological situation during activities of daily living of post-stroke and healthy subjects.
Measured: 7 days
Profil
The activity log is presented in the form of a table. The columns represent the days of recording (Day 1 => Day 7), the rows represent the time slots hour by hour
Measured: During intervention
Motor deficit
Motor deficit will be measured by the Fugl-Meyer Upper Extremity (FM-UE)
Measured: During the inclusion visit or information taken in the medical file
Dispersion of UseRatio
The dispersion of UseRatio (UseRatioDisp) over the 6 repeated measurements will be measured by the intra-patient interquartile range
Measured: 6 months

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
After a stroke, 80% of patients continue to have difficulty using their paretic upper limb in activities of daily living (ADL) despite post-stroke rehabilitation practices that aim to promote the use of the paretic upper limb. It is known that functional recovery depends on actual use (Use it or Loose it), but one-time measurements in the clinic do not allow quantification of the actual use of the paretic upper limb in daily life (in the person's living environment).
The investigators hypothesize the feasibility of quantifying functional use of the paretic upper limb by actimetry in clinical routine.

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 8 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
FuncUseRatio (time frame: 7 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Oct 2026.
