Key Findings

  • 01Significant improvements were observed in Fugl–Meyer assessment (FMA) scores (excluding proximal), Box and Block Test (BBT) score, Repeat Finger Flexion/Extension (Repeat-FE), Wolf Motor Function Test (WMFT) score, and Stroke Impact Scale (SIS) stroke recovery.
  • 02All active range of motion (AROM) values of finger joints showed significant changes during training.
  • 03Improvements were maintained at follow-up for most assessed metrics.

Application

Design takeaway

Incorporate precise, multi-joint tracking and engaging virtual environments into rehabilitation tools to maximize functional recovery.

How to apply

Develop or integrate MR systems that provide real-time, individual finger movement feedback for patients undergoing physical therapy, particularly for conditions affecting fine motor skills.

Project actions

  • 01When designing rehabilitation tools, think about how to track very specific body movements.
  • 02Consider how to make exercises fun and engaging, like in a game, to keep users motivated.

Method & Evidence

AimTo evaluate the effectiveness of a mixed reality system (MR-board 2) with individual finger movement tracking for hand and finger rehabilitation in stroke patients.
MethodQuantitative experimental study with pre-test, post-test, and follow-up measurements.
ProcedureParticipants with hemiplegic stroke underwent 20 self-training sessions using the MR-board 2 system, which included gamified training programs and real-time finger tracking. Outcome measures for upper extremity function were assessed before, during, and after the training period.
Sample21 participants
ContextStroke rehabilitation, assistive technology, human-computer interaction.

Variables

IVMixed reality rehabilitation with individual finger tracking (MR-board 2 training).
DVUpper extremity function scores (FMA, BBT, Repeat-FE, WMFT, SIS), active range of motion (AROM) of finger joints.
CVParticipant characteristics (age, sex, stroke onset, hemiplegia side), duration and frequency of training sessions.
04

Strengths & Limitations

Strengths

  • +Inclusion of objective measures like AROM and standardized clinical assessments.
  • +Assessment of both immediate and maintained effects through follow-up measurements.

Limitations

The sample size is relatively small, and the long-term effects beyond the follow-up period are not explored.

Reliability & validity

The study uses standardized clinical assessments (FMA, BBT, WMFT) which contribute to validity. The use of objective tracking data (AROM) enhances reliability. However, the sample size may limit generalizability.

Think critically

How might the cost and accessibility of such advanced MR systems impact their widespread adoption in clinical settings?

05

Design Principles
