Summary

A prospective, randomized, double-blind, sham-controlled trial designed to evaluate the effects of Repeated Muscle Vibration (rMV) on motor recovery in acute stroke patients treated within 72 hours of symptom onset

Detailed description

After enrollment (T0), patients are randomly assigned to either the vibration group (VG) or the control group (CG). Patients in the VG will receive rMV treatment, while those in the CG receive sham treatment. Both interventions are administered on the 1st, 2nd, and 3rd days post-enrollment. Physiokinesitherapy (PT) and occupational therapy (OT) are provided daily to all patients, starting immediately after the T0 clinical evaluation. Patients are re-evaluated after 4 ± 1 days (T-1), marking the end of the treatment period. Upon admission, demographic details and medical histories of all participants are recorded. Each patient undergoes clinical evaluations at all time points by an experienced investigator blinded to group allocation and distinct from the recruiting personnel. The clinical assessment includes stroke severity evaluation using the NIH Stroke Scale, motor and functional limb abilities using the Fugl-Meyer scale, SAFE score, and Motricity Index. Additionally, bioimpedance analysis of muscle mass and phase angle in the impaired upper limb is performed using the BWA device. All participants follow a standardized daily rehabilitation program. Physical therapists, blinded to treatment allocation, are instructed on the duration, frequency, and content of therapy to ensure consistency across groups. Low-amplitude rMV (frequency: 100 Hz; amplitude: 1-2 mm) is applied to the flexor carpi radialis and biceps brachii for upper limb treatment, using a commercial device (VibraMoov Physio, TechnoConcept, Mane, France). The rMV sessions are conducted over three consecutive days by two trained physiotherapists, with each daily session comprising three 10-minute treatments (per treated limb) interspersed with 1-minute breaks. During the rMV sessions, participants are instructed to perform voluntary isometric contractions of the treated muscle. In contrast, CG participants undergo sham rMV, where the vibrator is positioned near the tendon but without vibration.
