Abstract

OBJECTIVE:

To evaluate the immediate and long-term effects of 2 upper-extremity rehabilitation approaches for stroke compared with standard care in participants stratified by stroke severity.

DESIGN:

Nonblinded, randomized controlled trial (baseline, postintervention, 9mo) design.

SETTING:

Inpatient rehabilitation hospital and outpatient clinic.

PARTICIPANTS:

Sixty-four patients with recent stroke admitted for inpatient rehabilitation were randomized within severity strata (Orpington Prognostic Scale) into 1 of 3 intervention groups. Forty-four patients completed the 9-month follow-up.

INTERVENTIONS:

Standard care (SC), functional task practice (FT), and strength training (ST). The FT and ST groups received 20 additional hours of upper-extremity therapy beyond standard care distributed over a 4- to 6-week period.

MAIN OUTCOME MEASURES:

Performance measures of impairment (Fugl-Meyer Assessment), strength (isometric torque), and function (Functional Test of the Hemiparetic Upper Extremity [FTHUE]).

RESULTS:

Compared with SC participants, those in the FT and ST groups had significantly greater increases in Fugl-Meyer motor scores (P=.04) and isometric torque (P=.02) posttreatment. Treatment benefit was primarily in the less severe participants, where improvement in FT and ST group Fugl-Meyer motor scores more than doubled that of the SC group. Similar results were found for the FTHEU and isometric torque. During the long term, at 9 months, the less severe FT group continued to make gains in isometric muscle torque, significantly exceeding those of the ST group (P<.05).

CONCLUSIONS:

Task specificity and stroke severity are important factors for rehabilitation of arm use in acute stroke. Twenty hours of upper extremity-specific therapy over 4 to 6 weeks significantly affected functional outcomes. The immediate benefits of a functional task approach were similar to those of a resistance-strength approach, however, the former was more beneficial in the long-term.
