Efficacy of the Otago Exercise Program Delivered as Group Training Versus Individually Tailored Training

Efficacy of the Otago Exercise Program (OEP) Delivered as Group Training Versus Individually Tailored Training in Community-dwelling Adults Between 65 and 80 Years Old

A non-inferiority controlled clinical trial using randomization for allocation at the level of general practice in 21 centers (in 8 Spanish regions), to compare a group Otago exercise program (OEP) [delivered by specifically trained instructors and supplemented by prescriptive recommendations for home exercising], with an individual OEP [also delivered by specifically trained professionals and supplemented by prescriptive recommendations for home exercising], with twelve months follow-up to determine the effectiveness of the OEP in terms of prevention of falls in a community-dwelling 65- to 80-year-old population.

Study Overview

• Status: Completed
• Conditions: Age Problem
• Intervention / Treatment: Other: Otago Exercise Program (OEP)

Detailed Description

OBJECTIVES:

To compare the effectiveness of the Otago Exercise Program (OEP) delivered as group training versus individually tailored training in community-dwelling adults between 65 and 80 years old, on the probability of falls, improved functional balance and muscle strength and, quality of walk in the 12 months follow up.

To compare the effectiveness of both interventions to improve dynamic and static balance and gait quality in the same population.

DESIGN:

Non-inferiority clinical trial, multicentric, simple blind (blind analysis to prevent bias), with two interventions, implementation of group and individual OEP with random assign. The follow-up period will be twelve months after the OEP training.

FIELD OF STUDY:

21 Primary Health Centers (PHC) belonging to the National Health System in 8 different regions: Andalucía, Asturias, Islas Baleares, Canarias, Cataluña, Comunidad de Madrid, Región de Murcia and País Vasco

PARTICIPANTS:

Subjects who belong to primary care centers in the same health area, 65 to 80 years of age, who are not institutionalized, independent for walk (the score of the first part of the Short Physical Performance Battery scale (SPPB scale) in relation to balancing must be different from zero in any assessed position) and provide informed consent to participate in the study.

VARIABLES OF STUDY:

Principal Outcome: Percentage of falls (percentage of subjects falling)

Other Outcomes:

Safety of Intervention; Feasibility of interventions; Feasibility of the cascade training model based on the OEP; Economic analysis and added therapeutic value of both interventions.

DATA COLLECTION:

Subjects will be selected from the health centers through active recruitment by the health professionals.

The recruitment will be consecutive among the patients in the agenda in the days between 10 to 19 of each month from September 2017-December 2018.

Data will be collected at month 0, 6 and 12. Randomization will be performed by PHC and by subjects.

DATA ANALYSIS:

A descriptive analysis of sociodemographic and fall variables will be performed. The analysis to the comparative data between the two groups of the Randomize Clinical Trial will be done by protocol. In addition, an analysis will be made for the incidence density of falls, using Poisson regression models. For all a confidence level of 95% will be assumed, and the statistical software to be used to carry out the analysis will be Statistical Package for the Social Sciences version 22 (SPSS v22).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
No Intervention: Individual OEP; Randomized subjects (65 to 80-year-old) receiving individual Otago Exercise Program (OEP) training in a total of nine Primary Care Centers. An "OEP leader" trained nurse/physiotherapist will perform in its community consult individual education to each participant in five sessions: In the 1st, 2nd, 4th and 8th week and one reinforcement session after six months. A telephone call to each participant (following a predefined telephonic interview protocol) will be carried out in the months without training session to perform the follow-up.
Experimental: Group OEP; 65-80 year-old randomized subjects receiving group Otago Exercise Program (OEP) training in a total of nine Primary Care Centers.	Other: Otago Exercise Program (OEP); A nurse/physiotherapist supported by an "instructor"-trained professional will give Otago Exercise Program (OEP) education to 10-people groups in 5 sessions (1st, 2nd, 4th and 8th week and one reinforcement session after 6 months). Telephone calls to participants will be made during non-training months (following a predefined telephonic interview protocol) to follow up. The OEP reduces the number of falls and fall-related injuries, improving balance and strength, confidence in performing everyday activities without falling. Whilst it has been shown to be effective in 4 controlled trials in New Zealand, it has not been tested in a primary care setting in Spain for feasibility, impact, acceptability and cost-effectiveness.; Other Names: Usual Practice

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of falls	The participant will be provided with a notebook which should be completed each month. In the case a fall occur, the patient will be asked to fill the following items regarding the fall characteristics: Data, place, context in which the fall happened, consequences and attention required.	12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Adverse events	Adverse events during the intervention related to exclusion criteria (indication for a subject to leave the project); Adverse effects which can be directly or potentially associated with Otago exercises. For that, it will be established an external committee which will classify the adverse event among related, potentially related and none related with Otago exercise execution.	12 months
Adherence	Adherence level to exercise program will be measured following the Exercise Adherence Rating Scale (EARS) through self-declared falls diary. The EARS questionnaire is composed of 6 items, each of them is scaled from 0 (minimum) to 4 (maximum score). Total score is the sum of the 6 items, so that it ranges from a minimum score of 0 and a maximum score of 64. Adherence measurements will be collected at 6 and 12 months.	12 months
Participant satisfaction	Participant satisfaction with the intervention will be measured through "ad hoc" survey which include the following items: 4.1. Received information about exercise program and its benefits 4.2. Received Training about Otago Exercise Program 4.3. Assessment of Material 4.4. Teaching skills of your OEP trainer 4.5. Receptiveness of your health care professional to solve your doubts about the OEP 4.6. Global satisfaction with Otago Exercise Program Each item will be scaled from 0 (Totally unsatisfied) to 4 (Very satisfied). Total minimum and maximum scores are 0 and 64, respectively.	12 months
