Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Subjects were randomly divided into two groups. Group A carried out a ten-minute Mirror Therapy exercise daily, for a total duration of six weeks. Group B acted as a control group for six weeks followed by six weeks of Mirror Therapy with the same characteristics as Group A. Upper extremity active range of motion, strength, dexterity, limb volume, right-left temperature difference, and health-related quality of life were evaluated before and after each period. Daily records on the visual analogue scale were used for pain evaluation. Effectiveness was calculated using mixed-effects modelling for between-group comparisons and within-group variability and identifying significant predictors.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

Specifically, the study employs a half cross-over design. Group A begins with the intervention, while Group B starts with a control period of equal length, followed by the intervention. This design facilitates comparisons both between the groups and within Group B across the two periods.

Primary Study Purpose

TREATMENT

Blinding Strategy

NONE

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group A - Mirror Therapy

Group A carried out a ten-minute Mirror Therapy exercise daily, for a total duration of six weeks.

Group Type EXPERIMENTAL

Mirror Therapy exercise

Intervention Type OTHER

Mirror Therapy for the upper limb involves the use of a mirror to create a reflected image of the unaffected arm, making it appear as if both arms are moving symmetrically. During the therapy, the patient places their affected arm behind the mirror and their unaffected arm in front. While focusing on the mirror reflection, the patient performs various movements with the unaffected arm, giving the illusion that the affected arm is moving normally.

Group B - control period followed by Mirror Therapy

Group B acted as a control group for six weeks (no Mirror Therapy) followed by six weeks of Mirror Therapy with the same characteristics as Group A.

Group Type EXPERIMENTAL

Intervention Type OTHER
