Measure
Low Magnitude
voluntary forearm compression by leaning onto the palm of the hand with low target strain voluntary forearm loading task: voluntary task, consisting of leaning onto the palm of the hand until a target force is reached. Each loading bout consists of 100 loading cycles, which takes approximately 2 minutes to complete. The task is performed 4 times per week during the intervention period.
High Magnitude
voluntary forearm compression by leaning onto the palm of the hand with high target strain voluntary forearm loading task: voluntary task, consisting of leaning onto the palm of the hand until a target force is reached. Each loading bout consists of 100 loading cycles, which takes approximately 2 minutes to complete. The task is performed 4 times per week during the intervention period.
Low Rate
voluntary forearm compression by leaning onto the palm of the hand with low strain rate (task performed "slowly and evenly") voluntary forearm loading task: voluntary task, consisting of leaning onto the palm of the hand until a target force is reached. Each loading bout consists of 100 loading cycles, which takes approximately 2 minutes to complete. The task is performed 4 times per week during the intervention period.
High Rate
voluntary forearm compression by leaning onto the palm of the hand with high strain rate (task performed "as quickly as possible, with a bump") voluntary forearm loading task: voluntary task, consisting of leaning onto the palm of the hand until a target force is reached. Each loading bout consists of 100 loading cycles, which takes approximately 2 minutes to complete. The task is performed 4 times per week during the intervention period.

voluntary forearm compression by leaning onto the palm of the hand with high target strain voluntary forearm loading task: voluntary task, consisting of leaning onto the palm of the hand until a target force is reached. Each loading bout consists of 100 loading cycles, which takes approximately 2 minutes to complete. The task is performed 4 times per week during the intervention period.
Low Rate
n=15 Participants
voluntary forearm compression by leaning onto the palm of the hand with low strain rate (task performed "slowly and evenly") voluntary forearm loading task: voluntary task, consisting of leaning onto the palm of the hand until a target force is reached.

SECONDARY outcome

Timeframe: measurements repeated at 0, 3, 6, 9, and 12 months from enrollment

Population: Analysis population includes participants analyzed at at least one interim timepoint. Exact values are provided for individual timepoints below.

trabecular bone volume fraction expressed as the ratio of bone volume (BV) to total volume (TV) using: (BV/TV). This quantity is measured with high resolution peripheral quantitative computed tomography (HRpQCT). It is expressed as a ratio, ranging from 0 (none of the volume is occupied by bone) to 1 (all of the volume is occupied by bone).
