Comparison of Otago Exercises Versus Resistance Training on Functional Performance in Stroke Patients

December 1, 2023 updated by: Nouman Khan, Shifa Tameer-e-Millat University
Otago techniques are well known for addressing balance and strength deficiencies in healthy older population with fall risk. Despite this, there is limited literature about the Otago approaches' effectiveness in stroke patients. To the best of our knowledge, no research has been done in Pakistan to determine the effects of Otago exercises on chronic stroke patients.Otago exercises are easy to learn and create a sense of motivation and pleasurable activity when performed. To determine the effect of Otago exercises in treating poor balance control and reduced strength, the current study has chosen chronic stroke patients as its target population. The results of this study will serve as a manual for physical therapists on how to efficiently incorporate Otago Intervention into their treatment plans for better outcomes.

Detailed Description

Stroke is a focal neurological deficit. It causes functional impairments and activity limitation in the body after survival from the sudden attack, which includes disorders in language, movement, cognition and eating difficulties. Motor deficits are most common in stroke, it is directly related to reduction in strength, balance, gait speed and quality of life. Emotional and physical changes also occur, these factors combine to affect everyday activities. By improving functional performance and strength in lower extremity, it will improve gait speed and balance control.

Around the world among the major causes of death, stroke stands on the third number. Task-specific progressive resistance training uses the preserved energy in muscles to increase strength and balance. Training has to be carried out at a specific intensity and increase progressively which will lead to improvement in fitness and strength level. Progressive resistance training is an umbrella that consists of multiple different and unique set of interventions being used worldwide all with one primary target that is to use resistance and improve muscle strength. Because strength training has been proven to be beneficial in improving stroke symptoms, it has been included in this study.

Otago Exercise is an evidence-based strength and balance program. It has been shown to be effective in reducing the number of fall and fall-related injuries by 35%. The advantages of Otago exercise are that it is cost-effective, the exercise protocol is easy to learn and easy to perform. Once learned they can be performed at home by the patient without assistance or by using action observation technique. They are effective in improving lower extremity strength, balance and gait parameters in healthy older adults or people with disorders. This exercise program strengthens the antigravity extensors and increases proprioceptive input of the body by a stable base of support during mobility, thus improving muscle strength and overall improvement in balance control, walking speed and strength. Repeated movement will produce the effect of neuroplasticity in the brain producing efficient, controlled and meaningful movement.

Although Otago exercises have been used in previous studies worldwide and showed effectiveness in participants' strength and balance control. Recent evidence suggests that Otago exercises provide high-quality results to support its beneficial effects on reducing falls in osteoarthritic patients. It was also observed that this exercise program was safe and helped in improving balance and mobility in Alzheimer's disease. However, to our knowledge, there is limited literature available on the use of Otago exercises in chronic stroke patients in Pakistan.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Resistance Training

In Group A, Task oriented resistance training will be performed, there will be 5 workstations which include 2 task each given in the table below, after warm up exercises of head, neck, trunk and ankle.

Workstation 1: Sitting and reaching in different directions Sit to stand from different chair heights (higher to lower) Workstation 2: Step training (forward, backward, sideways) on blocks Heel lifts-sitting, standing (with and without support) Workstation 3: Reaching with narrow stance (feet in parallel, then in tandem stance) Reciprocal leg flexion and extension Workstation 4: Sit ups Chair stand and walk Workstation 5: Walking race Walking over obstacles This intervention will be given 3 times per week for 4 weeks, every station takes 5-6 minutes and the total intervention will be completed in 50-60 minutes.
Other: Resistance training

Task oriented resistance training will be performed, there will be 10 workstations:

  1. Sitting at a table and reaching in different directions for objects located beyond arm's length.
  2. Sit to stand from various chair heights
  3. Stepping forward, backward and sideways onto blocks of various heights.
  4. Heel lifts in standing
  5. Standing with narrow base of support, feet in parallel and tandem stance and reaching for objects, including down to the floor.
  6. Reciprocal leg flexion and extension.
  7. Sit ups
  8. Standing up from chair, walking a short distance and returning to the chair.
  9. Walking races between participants
  10. Walking over various surfaces and obstacles
Experimental: Otago Exercises

Group B will be given Otago exercises, it has 17 exercises in total. 5 for strength and 12 for balance training.

To assess static balance There are four standing positions that get progressively harder to maintain.

  1. Stand with your feet side-by-side.
  2. Place the instep of one foot so it is touching the big toe of the other foot.
  3. Tandem stand: Place one foot in front of the other, heel touching toe.
  4. Stand on one foot.

to determine gait speed, balance and fall risk The patient stands up upon therapist's command: walks 3 meters, turns around, walks back to the chair and sits down.

The time stops when the patient is seated.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Stroke Specific Quality of Life
Time Frame: 4 weeks
The Stroke Specific Quality Of Life scale (SS-QOL) is a patient-centered outcome measure intended to provide an assessment of health-related quality of life (HRQOL) specific to patients with stroke. Patients must respond to each question of the SS-QOL with reference to the past week. It is a self-report scale containing 49 items in 12 domains. Items are rated on a 5-point Likert scale. The total score ranges from 49 to 245, with higher scores indicating a better QOL.
