Conditions
Brief summary
This study aims to examine the feasibility, safety, and patient satisfaction of a high speed resistance training program with and without balance exercises in people with knee osteoarthritis compared to a control group. Given the pain associated with knee osteoarthritis, it is crucial to determine what effect high speed resistance training that focuses on muscle power has on knee pain. The effect of the exercise interventions on strength, physiological and functional risk factors for falls, pain, and executive function will also be assessed.
Interventions
Two intervention arms will be included:
Eight weeks of high speed strengthening exercise program (twice per week)
or
Eight weeks of combination of high speed strengthening and balance exercises (twice per week).
High speed resistance training: the program will include 6-8 exercises targeting the lower limbs as follows: leg press, squat, step-up, lunges, going up stairs, sit to stand, calf raises. Exercise program will be performed twice a week for 8 weeks for approximately 30min for each exerci
Two intervention arms will be included: Eight weeks of high speed strengthening exercise program (twice per week) or Eight weeks of combination of high speed strengthening and balance exercises (twice per week). High speed resistance training: the program will include 6-8 exercises targeting the lower limbs as follows: leg press, squat, step-up, lunges, going up stairs, sit to stand, calf raises. Exercise program will be performed twice a week for 8 weeks for approximately 30min for each exercise session. Participants will be instructed to perform the exercises in a rapid and explosive manner. The 8 weeks program will be divided into the following phases to allow gradual progression and increase of the resistance for the high speed resistance training exercises (weight/training load) as follows: Phase 1 – week 1-2 (4 sessions). Participants will perform 2 sets of 8-12 repetitions with 20-40% 1RM Phase 2 – week 3-5 (6 sessions). Participants will perform 2 sets of 5-10 repetitions with 40-60% 1RM Phase 3 – week 6-8 (6 sessions). Participants will perform 2-3 sets of 2-5 repetitions with 60-80% 1RM Intensity will be monitored using the RPE scale with expected RPE between 11-17/20. High speed resistance and balance training: the program will include the same exercises as the high speed resistance training group with the addition of 6 balance exercises. Exercise program will be performed twice a week for 8 weeks for approximately 45min for each exercise session. The balance exercises will include the following: walking forward and backward, single leg standing, single leg tapping, side stepping and backward walking. Each balance exercise will initially be of 15-30 seconds duration and be performed twice per session. Both exercise programs of both groups will be supervised by accredited exercise physiologist or physiotherapist. Exercise sessions will be one on one with the participants and will take place at Victoria University Exercise Rehabilitation Clinic, Footscray Campus. Attendance will be monitored using individual training log to be recorded by the supervisor.

Inclusion criteria
Participants aged 60-90 years with knee osteoarthritis who have had a fall in the previous 12 months or who are concerned about having a fall will be recruited. Participants will need to have knee pain for at least 6 months and experience current average pain of at least 3 (on an 11 point numerical rating scale) and be able to ambulate independently.
Exclusion criteria
1) any uncontrolled non-musculoskeletal conditions that would make testing difficult and uncomfortable, such as chronic obstructive airways disease and congestive heart failure; 2) a pre-existing neurological condition that affects lower limb strength, balance and or ambulation (e.g. polio, stroke); 3) any uncontrolled musculoskeletal or orthopaedic conditions that may affect ambulation (rheumatoid arthritis, gout, etc.); 4) currently taking part in a structured resistance training and or an organised balance training program more than once a week; 5) Participants with any documented medical condition or physical impairment that is deemed by the medical practitioner to contraindicate their inclusion will be excluded from the study ; 6) participants with severe cognitive impairment or dementia
