Study Description

Brief Summary:

Although there is some evidence that whole body electromyostimulation(WB-EMS) affect bone via its acute and longitudinal effects on muscle mass and strength, the corresponding impact on bone density and falls in older adults has not been assessed yet. The investigators hypothesize that WB-EMS significantly affects bone parameters as assessed by DXA, and significantly reduce fall rate and ratio in a cohort of frail elderly women.

Condition or disease	Intervention/treatment	Phase
Osteopenia; Sarcopenia; Falls	Other: wellness control group.; Device: whole-body electromyostimulation	Phase 3

• Allocation: Randomized
• Intervention Model: Parallel Assignment
• Masking: Triple (Participant, Care Provider, Outcomes Assessor)
• Primary Purpose: Treatment
• Official Title: Effects of Whole-Body Electromyostimulation on Osteoporosis and Sarcopenia in Independently Living, Frail Elderly Females

• Actual Study Completion Date: December 2012

Arms and Interventions

Arm	Intervention/treatment
Active Comparator: whole-body electromyostimulation; 20 min of whole-body electromyostimulation with sequences of 6 sec of current and 4 sec at 85 Hz performed during low-intensity/low amplitude movements. 3 sessions / 14 days for 12 months	Device: whole-body electromyostimulation; 3 sessions of 18 min/14 (1,5 x week)days over 12 months. 10 low-intensity/low amplitude exercises with electromyostimulation equipment with 85 Hz with periods of 6 sec of current and 4 sec of rest.; Other Names: Electromusclestimulation, electrostimulation; Miha-bodytec
Placebo Comparator: wellness control group; Low intensity, low frequency exercise that focus on well being. 1 session/week for 10 weeks. 10 blocks of exercise with intermittent periods of 100 weeks of rest	Other: wellness control group.; Light physical exercise and relaxation program once a week in blocks of 10 weeks with breaks of 10 weeks between the blocks. The low-intensity, low-volume program was designed to avoid impact on our endpoints.; Other Name: functional gymnastic, flexibility, relaxation.

Outcome Measures

Primary Outcome Measures :

1. Bone Mineral Density at the lumbar spine and femoral neck region [ Time Frame: baseline - after 12 months ]
   Bone Mineral Density as assessed by Dual Energy X-ray Absorptiometry
2. Falls [ Time Frame: throughout the 12 month study period ]
   Fall frequency and fall related injuries as assessed by the calendar method

Secondary Outcome Measures :

1. maximum strength (trunk and leg extension, grip strength) [ Time Frame: baseline - after 12 months ]
2. Pain frequency and magnitude at various skeletal sites (including low back pain) [ Time Frame: baseline - after 12 months ]
   as assessed by questionnaires
