Contralaterally controlled functional electrical stimulation improves wrist dorsiflexion and upper limb function in patients with early-phase stroke: A randomized controlled trial.

OBJECTIVES

To investigate the effectiveness of contralaterally controlled functional electrical stimulation (CCFES) on the recovery of active wrist dorsiflexion and upper limb function in patients with early-phase stroke (<15 days post-stroke).

METHODS

Patients in the CCFES group were treated with routine rehabilitation combined with CCFES, while those in the conventional neuromuscular electrical stimulation (NMES) group were treated with routine rehabilitation combined with NMES. Time intervals from stroke onset to appearance of wrist dorsiflexion, and from onset of treatment to appearance of wrist dorsiflexion were recorded (in days). Functional assessments were also performed at baseline and endpoint.

RESULTS

Nineteen out of 21 patients in the CCFES group and 12 out of 20 patients in the NMES group regained active wrist dorsiflexion during the treatment and follow-up period (90.5% vs 60%, p =  0.025). The mean time interval from onset of treatment to appearance of active wrist dorsiflexion was signifcantly shorter in the CCFES group than in the NMES group (p < 0.001). The CCFES group had signifcantly higher scores for upper extremity function (p =  0.001), strength of extensor carpi (p =  0.002), active ROM for wrist dorsiflexion (p =  0.003), activities of daily living score (p =  0.023) and ICF score (p < 0.001) than the NMES group at the endpoint.

CONCLUSION

CCFES signifcantly shortened the time for regaining wrist dorsiflexion, and improved the upper extremity function and general health of patients with early-phase stroke. CCFES therefore has potential as a clinical intervention.
