Brief Summary

Stroke is associated with disability and impaired quality of life. Persistent motor impairment is common with incomplete recovery of motor function after rehabilitation, mainly in the upper limbs (UL). Robot-mediated therapy (RMT) has been proposed as a viable approach for the rehabilitation of the UL, but more rigorous studies are needed to tailor rehabilitation and to better address the treatment. Brain-derived neurotrophic factor (BDNF) and the serotonin transporter gene (SLC6A4) have been shown to play an important role in post-stroke recovery. After ischemic stroke, disruption and subsequent reorganization of functional brain connections occur both locally and far from the lesion, with the latter possibly contributing to function recovery. This project aims to assess whether epigenetic and genetic variations of BDNF and SLC6A4 can occur in stroke patients after robotic rehabilitation treatment. This study will allow to identify potential genetic and epigenetic biomarkers in post-stroke rehabilitation that could be used to predict the response to a specific rehabilitation treatment and to choose the optimal treatment for the patient (Rehabilomics).

Outcome Measures

Primary Outcomes (2)

  • Presence/absence of rs6265 in the BDNF

    BDNF rs6265 polymorphism will be analyzed using HpyCH4IV restriction enzyme which identifies homozygous Valine/Valine, heterozygous Valine/Methionine and homozygous Methionine/Methionine

    Baseline (T0)

  • Presence/absence of 5-HTTLPR in the SLC6A4

    SLC6A4 5-HTTLPR polymorphism will be analyzed by a specific protocol that identifies gene polymorphisms according to the polymerase chain reaction (PCR) fragment sizes: short \[S; 486 base pairs (bp), 14 repeats\], long \[L; 529bp, 16 repeats\], or extra-long \[XL; 612 or 654bp, 20 or 22 repeats\].

    Baseline (T0)

Secondary Outcomes (2)

  • Change in promoter methylation levels of BDNF gene

    Baseline [T0], First Treatment (6 weeks and 30 rehabilitation session) [T1], Second treatment (other 6 weeks and other 30 rehabilitation session) [T2]

  • Change in promoter methylation levels of SLC6A4 gene

    Baseline [T0], First Treatment (6 weeks and 30 rehabilitation session) [T1], Second treatment (other 6 weeks and other 30 rehabilitation session) [T2]

Other Outcomes (9)

  • Change in Fugl-Meyer Assessment of Motor Recovery after Stroke for Upper Extremity portion (FMA-UL)

    Baseline [T0], First Treatment (6 weeks and 30 rehabilitation session) [T1], Second treatment (other 6 weeks and other 30 rehabilitation session) [T2]

  • Change in Modified Barthel Index (BI)

  • Change in Motricity Index (MI)

    Baseline [T0], First Treatment (6 weeks and 30 rehabilitation session) [T1], Second treatment (other 6 weeks and other 30 rehabilitation session) [T2]

  • +6 more other outcomes

Study Arms (1)

Stroke patients

Inpatients and outpatients admitted to the investigators' rehabilitation facility with an upper limb impairment due to neurologic or orthopedic disorders.

Device: Robotic assisted intervention

Interventions

Robotic treatment of the upper limb (30 sessions, 5 times a week) using a set of 4 robotic devices: Motore (Humanware); Amadeo, Diego, Pablo (Tyromotion). The training will include motor-cognitive exercises specifically selected to train spatial attention, vision and working memory, praxis, executive function, and speed of processing.

Stroke patients

Eligibility Criteria

Age55 Years - 85 Years
Sexall
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The investigators will enroll both inpatients and outpatients admitted to their rehabilitation facility with an upper limb impairment due to neurologic or orthopedic disorders.

You may qualify if:

  • sub-acute patients, with ischemic or hemorrhagic stroke, documented by MRI or CT;
  • age between 55 and 85 years;
  • patients able to perform a rehabilitation treatment focused on the UL, for at least 45 min/day, for 5 days/week;
  • time latency since stroke ranging from 2 weeks to 6 months,
  • cognitive and language abilities sufficient to understand the experiments and follow instructions.

You may not qualify if:

  • a previous stroke;
  • behavioral and cognitive disorders and/or reduced compliance interfering with active therapy;
  • fixed contraction deformity in the affected limb interfering with active therapy (ankylosis, Modified Ashworth Scale = 4);
  • severe deficits in visual acuity;
  • upper extremity Fugl-Meyer score \>58.
