Exercise Intervention to Reduce Postural Instability in Osteoarthritis

Completed · Not applicable

Conditions studied: Osteoarthritis

In brief

This is a one year pilot study evaluating the feasibility of a 10 week, twice weekly, group functional exercise sessions in individuals with knee osteoarthritis and its effect on gait and balance measures.

Who can join

Age: 50 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age 50 and older.
• Corrected vision not worse than 20/50.
• Ability to ambulate household distances without an assistive device - minimum functional status for ambulation as primary mode of mobility.
• Presence of knee OA based on clinical and radiological criteria.

You may not qualify if…

• Cognitive impairment with Mini Mental State Exam (MMSE) score <24; Scores at or below 24 indicate cognitive impairments, limiting ability to participate in the group and/or remember instructions.
• Metastatic cancer, since this limits ability to fully participate in the group and/or complete the intervention due to limited life expectancy and changing functional status.
• Central or peripheral neurological dysfunction e.g. diagnosis of hemiparesis, cerebellar dysfunction, Parkinson's disease , peripheral neuropathy with or without foot drop, as determined by medical record review and physical exam; Severe Peripheral Vascular Disease with claudication or Spinal Stenosis with pseudoclaudication/chronic low back pain; These impairments would further impair gait and balance, and would jeopardize safety during the intervention and/or confound the effect of the intervention.
• Lower extremity amputations, or foot deformities; Mobility limitations due to altered lower extremity skin integrity/ulcer, where weight-bearing would be contraindicated (foot ulcers), since this would affect gait and balance measures.
• Use of medications known to impair balance, e.g. antipsychotics, benzodiazepines, anti-epileptics, etc. which would affect gait and balance measures.
• Severe arthritis limiting basic activities of daily living (ADL) and were offered or are pending joint replacement, since it is unlikely that any non-pharmacological intervention would be effective.
• Total knee replacement on one or both sides, since gait and balance changes due to total knee replacement would confound the effect of interventions.
• Current involvement in physical therapy, since it would confound results.
• Medically unstable upon exam, i.e. poorly controlled blood pressure or blood sugar, unstable coronary artery disease, since group participation may compromise medical status.
• Morbid obesity (BMI>40) due to potential changes in gait variables (speed, cadence, stride length).
• Weight over 300 pounds (due to limitations of Neurocom force plate).
