Intervention goals
• 1. Resolve, reduce, or prevent impairments in systems that are important to balance
• 2. Develop effective task-specific sensory, motor, and cognitive strategies
• 3. Retrain functional tasks with varying postural control demands under changing environmental contexts
Task Oriented Training = Integrative
• Motor Aspects• Steady-State Strategy Training• Reactive Balance Training• Anticipatory Balance Training
• Sensory Aspects• Training to increase vestibular response• Incorporate multi-sensory cues (
• Cognitive training: • single to dual task condition
Motor - Intervention Strategies
• Steady-State Strategies• Ankle-hip-trunk control strategies to maintain CoM over Bos
• Progressive stance to challenge LoS
• Anticipatory or Proactive Control Strategies• Transitional movements (change in body positions)
• Mobility-related tasks
• Reactive Control Strategies• Reaction time with stepping strategy
• Equilibrium response

Sensory and Cognitive Strategies
SENSORY-RELATED
• Vestibular integration
• Visual and visual motor integration
COGNITIVE-RELATED
• Dual task training
• Problem solving
Motor Learning Principles
• Practice • Increased intensity• Varying schedules: Random vs. Blocked
• Environment• Practice in various conditions: predictable unpredictable• Virtual and real life contexts
• Feedback • Intrinsic motivation and sense of self-efficacy• Therapeutic feedback: Knowledge of results (KR), knowledge of
performance (KP)

Virtual Reality defined
• Virtual reality (VR) is a form of computer-based technology that simulates human activities, environments, and the interactions between humans and their environment in the actual world.

• Sensory and Cognitive Demands• Visual tracking• Depth perception• VOR and OKR integration• Dual-task attention
Wii Fit Set-Up
Requires initial calibration based on
1. BMI analysis
2. Fitness analysis• Measurement of
Center of Gravity
• Balance screening (variable)

Tilt Table
Activity Analysis: Tilt Table
• Required balance and postural control• Steady-state balance with hip strategies • Multi-directional weightshifts• Pace of movement: slow to intermediate
• Required cognitive and perceptual skills• Low level VOR integration• Significant somatosensory input• Dual cognitive tasks
• Required standing tolerance• Initial 30 seconds will extend up to 5 minutes
Ski Slalom

Activity Analysis: Ski Slalom
• Required balance and postural control• Steady-state balance with hip strategies • Repetitive medio-lateral weightshifts• Pace of movement: intermediate to fast
• Required cognitive and perceptual skills• OKR and VOR integration – busy visual stimuli• Significant somatosensory input• Dual cognitive tasks
• Required standing tolerance• Usually 60 seconds at a time
Wii Soccer
Activity Analysis: Soccer
• Required balance and postural control• Steady-state balance with ankle and hip strategies • Repetitive antero-posterior weightshifts• Pace of movement: intermediate to fast
• Required cognitive and perceptual skills• OKR and VOR integration – busy visual stimuli• Significant depth perception• Dual cognitive tasks
• Required standing tolerance• Usually 75-90 seconds at a time

Wellness and Productive Aging
Settings:
• Senior centers
• Assisted living
• Retirement Communities
Health Goals:
• Maintain physical fitness including balance and endurance/ activity tolerance
• Promote socialization
Wellness/Productive Aging
• Allows partners to engage in activities together
• Encourages participation in leisure time interests and sports
Bondoc, Hewitt & Benard, 2010
Pilot Program @ Elim Park
• Each participant is evaluated for Wii “readiness” and to identify specific needs
• The program was held weekly over 7 weeks
• Each session ran 45-60 minutes long

Evaluation1. Occupational Profile2. Medical history 3. Performance Skills and Client Factors:
• Vision, visual perceptual skills and visual motor skills• Balance, postural control and gross motor coordination• Ambulation/mobility status incl. AD needs• UE Range of motion • Fine motor coordination• Cardiovascular and activity tolerance
4. Occupational Patterns• Typical routine and use of time• Leisure activities – past (given up), present
5. Participant Goals
Wellness Program Protocol• Week 1-2: Activities and Objectives:
1. Become familiar to the set-up and controls of the Wii 2. Create a Mii avatar3. Decide the best positioning for the participant during gaming (sitting,
standing) in relation to the monitor4. Trial one or two simple games5. For carry over, continue playing trial games with Recreation Director
• Week 3-4: Activities and Objectives:1. Review independent training program2. Review recommended cues from Week 1 training session to increase
independence with navigation of the game 3. Trial more games; participate games with or other residents, friend or
spouse 4. Evaluate participants’ independence in doing the games themselves5. Evaluate need for adaptations or review of how to operate the device
Wellness Program Protocol
• Week 5-6: Activities and Objectives:1. Facilitate group interactions – where they can be more
independent; encourage those who are independent to teach others/ entice others to join.
2. Final competency check: Have resident do a return demo / repeat instructions and strategies
3. Encourage participating in competitive leagues within the institution and extramurals
• Week 7: Activities and Objectives:1. Review of progress towards goals2. Re-evaluation of performance skills and occupational
performance3. Discuss with Recreation Director ways to promote carry-
over

Geriatric Rehabilitation
Goals of Therapeutic Interventions
1. Endurance/Activity Tolerance Building
2. Cognitive Training
3. Balance Training
4. Flexibility and AROM Promotion
** Stimulated continued interest in participation in therapy programs**
Geriatric Rehabilitation
Therapeutic Rationale for Endurance Building
1. Participate along mobility continuum:• Seated only
• Sit to stand transitions
• Standing for the entire game
2. Timed participation• Measured by number of rests needed
• Number of games played
• Length of time of participation in a game.
Geriatric Rehabilitation
Therapeutic Rationale for Cognitive Integration
1. Incorporates sensory perceptual skills and motor planning (anticipatory control)
2. Executive Function: Problem Solving and Sequencing
3. Attention and Online Awareness
4. Procedural Memory

SideNote: Cognitive Considerations
• What type of cues work best for the patient?• Verbal – must be short and concrete• Physical/ Manual – i.e., hand over hand, guidance
• Document type and amount of prompting
• Short term memory loss may affect the ability to understand how the game works from one session to the next or one game to the next
• Consider the environment, be aware of a “sun downing” effect, make sure there is enough light in the room to not induce sleepiness.
Geriatric Rehabilitation
Therapeutic Rationale for Balance Facilitation
• Dynamic standing• With or without device
• Can be graded: walker quad cane 1-pt cane
• Low impact simulation of games/sports• Steps approaching bowling lane
• Sidesteps toward tennis ball with trunk rotation
• Reaching in various ranges to pop bubbles with finger
Geriatric Rehabilitation
Therapeutic Rationale for Flexibility and AROM
• Functional upper extremity movement patterns
• Nintendo Wii Sports: • Tennis, bowling and golf games are self-calibrating
• Progressively gets more challenging (Levels)
