Botulinum Toxin Type A and Modified Constraint-Induced Movement Therapy for Poststroke Upper Extremity Spasticity - Full Text View

Purpose

Botulinum toxin type A (BtxA) injection and modified constraint-induced movement therapy (mCIMT) are both promising approaches to enhance recovery after stroke. However, the combined application of the two modalities has rarely been studied. The aim was to investigate whether combined BtxA and mCIMT would produce greater improvements in spasticity and upper extremity function than BtxA plus conventional rehabilitation in chronic stroke patients with upper extremity spasticity.

Primary Outcome Measures:

The primary outcome assessed spasticity on the Modified Ashworth Scale. [ Time Frame: MAS evaluated before BtxA injection, at 4 weeks, 3 months and 6 months postinjection. ]

Secondary Outcome Measures:

Secondary outcomes assessed real-world arm function (Motor Activity Log), laboratory motor activity (Action Research Arm Test) and patients' global satisfaction. [ Time Frame: evaluated before BtxA injection, at 4 weeks, 3 months and 6 months postinjection. ]

Arms	Assigned Interventions
Experimental: 1 BtxA+mCIMT (combination group)	Other: BtxA+mCIMT The combination group receive BtxA+mCIMT for 2 hours/day, 3 days/week for 3 months. Other Name: the combination group
Placebo Comparator: 2 BtxA+ conventional rehabilitation (control group)	Other: BtxA+ conventional rehabilitation The control group received for 2 hours/day, 3 days/week for 3 months. Other Name: the control group

Detailed Description:

Botulinum toxin type A (BtxA) injection and modified constraint-induced movement therapy (mCIMT)are both promising approaches to enhance recovery after stroke. However, the combined application of the two modalities has rarely been studied. To date, only a single case report addressed this issue. Theoretically, application of a mCIMT program with intensive functional tasks practice after spasticity reduction by BtxA may improve affected upper extremity function in patients with poststroke spasticity. The aim was to investigate whether combined BtxA and mCIMT would produce greater improvements in spasticity and upper extremity function than BtxA plus conventional rehabilitation in chronic stroke patients with upper extremity spasticity.
