Effect of a dynamic wrist-hand orthosis combined with modified constraint-induced movement therapy on upper limb and hand function in acute and sub-acute stroke patients: a randomized controlled trial.

In 30 seconds

This assessor-blinded, two-part randomized controlled trial evaluated adding a SaeboGlove dynamic wrist-hand orthosis to modified constraint-induced movement therapy (mCIMT) in people with acute or sub-acute stroke. In Part A, 18 participants receiving the combined intervention were compared with 19 receiving mCIMT alone; in Part B, 10 receiving the combination were compared with 9 controls. The combined group scored 7.23 points higher on the Wolf Motor Function Test than the mCIMT-only group (95% CI 1.93 to 12.53). The authors conclude that the orthosis may enhance mCIMT benefits and broaden eligibility.

Key findings

• In Part A, the combined-intervention group scored 7.23 points higher on the WMFT than the mCIMT-only group (95% CI 1.93 to 12.53; P < 0.05).
• In Part A, WMFT hand-grip strength was 3.29 points higher with mCIMT plus SaeboGlove than with mCIMT alone (95% CI 1.35 to 5.24; P < 0.01).
• In Part B, the combined group scored 5.45 points higher on the WMFT than controls (95% CI 1.92 to 8.98; P < 0.01).
• In Part B, the combined group had an ARAT score 10.75 points higher than controls (95% CI 0.93 to 20.57; P < 0.05).

Why it matters

Limited ability of the affected limb can prevent some people from undertaking mCIMT. These trial results suggest that an orthosis may support functional and grip-strength gains when mCIMT is used, including among people who might not otherwise qualify. This addresses a practical barrier to delivering a rehabilitation approach, while the findings remain specific to the interventions and outcomes studied.

What to keep in mind

The trial groups were small, with 9 to 19 participants each, and the abstract reports outcomes from a three-week intervention without describing longer-term follow-up.
