Details and patient eligibility

About

Balance control, physical activity and health related quality of life will be assessed before and after a 10 to 12 weeks training program as well as 6 and 12 months thereafter in 200 elderly (>60) with balance problems (100 with osteoporosis, 100 with Parkinson's disease). Osteoporosis subjects will be assigned to 3 groups (balance training, balance training and Nordic walking, or control group) and Parkinson's subjects to 2 groups (balance training or a control group). The training will be progressive and specific incorporating dual task exercises (directly related to an increased risk of falling). Clinical and laboratory gait and balance measures as well as questionnaires will be used to assess physical function and quality of life. An earlier study, investigating this training program in healthy elderly with balance problems showed that the training was well-tolerated and effective, with a significant increase in balance control, physical function and activity. In this study, we expect that an improvement in balance function, physical activity and health related quality of life, which will lead to a decreased number of falls, prevent and/or postpone incidence of a hazardous fall and thereby reduce the burden on the health care system. Our model for functional balance training and outcome methods will expand techniques and tools available to physical therapists and health care scientist treating and evaluating patients with loss of balance function. Elderly receiving therapy with the goal to improve or recuperate physical function and balance will benefit from this project.

Inclusion and exclusion criteria

• Osteoporosis: To be included the candidate must: be >65 years with osteoporosis objectively verified by Dual energy X-ray absorptiometry (DXA) in the hip and lumbar back,be an independent ambulator, have experienced at least one fall in the last 12 months and have an adequate medical treatment for their osteoporosis.
• Parkinson's disease: All PD subjects will have a clinical diagnosis of -idiopathic‖ PD (Hoehn &Yahr scores 2-3), > 60 years of age and no other existing neuromuscular disorders, including severely flexed posture. In addition, the subjects will have no history suggesting -atypical‖ PD symptoms.

Exclusion criteria's for all subjects are:

• moderate-severe dementia (Mini-Mental score <24)
• respiratory, cardiovascular, musculoskeletal or neurological (except PD) disorders that may interfere with participation in the exercise program

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

---

200 participants in 3 patient groups

Gait and balance group training

Experimental group

Description:

The balance-training program is based on scientifically well-established principles of exercise training and postural control as well as current research on training in elderly and PD. For the PD group it has been modified based on the current knowledge of the neurophysiology and the inevitable constraints on mobility and postural control resulting from basal ganglia degeneration. The training will be conducted as a progressive individually adjusted group program, led by experienced physiotherapists and researchers in order to challenge the specific balance disorder of every participant and endorse progression. It is progressive and specific balance program including dual- and multitasks. The program is performed 3 times/week for 10-12 weeks.
