Brief Summary

This is a pilot randomised controlled trial investigating a combination of unilateral strength training (cross-education) and mirror therapy for the rehabilitation of lower limb impairment following a stroke. This study has been conducted as part of a PhD qualification at the Institute of Technology Sligo in Ireland with all assessments being conducted at the institute and all therapy sessions taking place at the participant's home. The study was conducted in conjunction with Sligo University Hospital and it attained ethical approval through the relevant University Hospital Ethics Committee.

Conditions

Stroke

Outcome Measures

Primary Outcomes (1)

• Maximal Isometric ankle dorsiflexion Strength.

  Assessed with the Biodex System 3 Pro Isokinetic Dynamometer with the Biodex Advantage Software version 3.45 (Biodex Medical Systems, Inc., Shirley, New York, USA). Peak Torque, Rate of Torque Development and Average Torque over a single contraction was analysed. A higher torque measurement indicates a greater contraction strength.

  10 minutes

Secondary Outcomes (4)

• Modified Ashworth Scale (MAS).

  10 minutes.

• Timed Up and Go (TUG).

  5 minutes.

• 10 Metre Walk Test (10MWT).

  5 minutes.

• London Handicap Scale (LHS).

  10 minutes

Study Arms (2)

Mirror Therapy + Cross-Education.

EXPERIMENTAL

Patients performed 4 sets of 5 maximal isometric ankle dorsiflexions with their less-affected lower limb while observing the reflection of the exercising limb in the mirror which was placed in the patient's mid-sagittal plane. Training sessions took place 3 days per week for four weeks in the participant's own home under the supervision of 2 exercise professionals.

Device: Mirror Therapy; Other: Cross-Education of Strengthening.

Cross-Education of Strengthening.

ACTIVE COMPARATOR

Patients trained without a mirror entirely. They performed 4 sets of 5 maximal isometric ankle dorsiflexions with their less-affected lower limb. Training sessions took place 3 days per week for four weeks in the participant's own home under the supervision of 2 exercise professionals.

Other: Cross-Education of Strengthening.

Interventions

Mirror Therapy DEVICE

Mirror Therapy involved the patient sitting on a chair with a standard mirror placed between both legs with the reflective side of the mirror facing the non-affected leg. The patient is instructed to observe the reflection of the non-affected limb during the sessions. The patient was not given any instruction on the use of the affected limb.

Mirror Therapy + Cross-Education.

Cross-Education of Strengthening. OTHER

Cross-education of strengthening involves training one side of the body with the intention of producing strengthening gains on both sides of the body. In this case the strengthening was done on the non-affected leg of each stroke patient.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Chronic stroke diagnosed by a physician at least 6 months prior to study begin Discharged from formal rehabilitation services (not receiving outpatient rehabilitation on more than a monthly basis, but may still be in receipt of occupational or language therapy).

You may not qualify if:

• Impaired cognition (Mini mental state examination (MMSE) \< 21) Cardiovascular, neurological or musculoskeletal impairments of the lower extremity not related to stroke that would prevent strength training.
• Visual impairments that would interfere with the ability to participate safely in isometric training and observe mirror images.
