Trial Description

Botulinum toxin type A (BoNT-A) is widely used in the clinics to reduce spasticity and improve upper limb function for post-stroke patients. However, there were no studies to compare the effect of rESWT and BoNT-A injection for treatment on spasticity.

Detailed Description

Botulinum toxin type A (BoNT-A) is widely used in the clinics to reduce spasticity and improve upper limb function for post-stroke patients. However, the treatments of BoNT-A injection are associated with high cost and invasive treatment. Recent studies have showed that radial extracorporeal shock wave (rESWT) is a novel, effective and safety treatment method for the spasticity. However, there were no studies to compare the effect of rESWT and BoNT-A injection for treatment on spasticity.

Conditions

Interventions

  • Botulinum toxin A Drug
    Intervention Desc: 42 chronic stroke patients with upper limb spasticity were randomly assigned to receive either 1 session of ESWT per week for 3 consecutive weeks or BoNT-A injection. The biceps, flexor carpi radialis, and flexor carpi ulnaris muscles were treated. Assessments were performed at baseline and at 1, 4, and 8 weeks after the intervention. The primary outcome measure was the change in the Modified Ashworth Scale (MAS) score for the elbow from the baseline to after 4 weeks of treatment.
    ARM 1: Kind: Experimental
    Label: Botulinum toxin A
    Description: We performed BoNT-A 500 unit in 2cc 0.9% normal saline at biceps brachii, flexor carpi ulnaris and flexor carpi radialis, mainly in the middle of the belly.
  • Shock Wave Device
    Intervention Desc: 42 chronic stroke patients with upper limb spasticity were randomly assigned to receive either 1 session of ESWT per week for 3 consecutive weeks or BoNT-A injection. The biceps, flexor carpi radialis, and flexor carpi ulnaris muscles were treated. Assessments were performed at baseline and at 1, 4, and 8 weeks after the intervention. The primary outcome measure was the change in the Modified Ashworth Scale (MAS) score for the elbow from the baseline to after 4 weeks of treatment.
    ARM 1: Kind: Experimental
    Label: shock wave
    Description: The interventions were focused in the hypertonic muscles of the upper limb of 3000 impulses, a pressure of 1.5 bar and frequency of 5Hz were used to treat the biceps brachii, flexor carpi ulnaris and flexor carpi radialis, mainly in the middle of the belly.

Outcomes

Type Measure Time Frame Safety Issue
Primary The change of spasticity of elbow Between baseline and 4 weeks post-treatment
Secondary The change of Tardieu scale scores for the elbow and wrist Between baseline and 1, 4,8 weeks post-treatment
Secondary The change of upper limb function Between baseline and 1,4,8 weeks post-treatment
