Effect of Leg Strengthening Exercise After Hip Fracture

Phase 1

Completed

• Conditions: Hip Fractures
• Interventions: Other: progressive resistance exercise; Other: TENS

• Registration Number: NCT00997776
• Lead Sponsor: Arcadia University

Brief Summary

The purpose of this trial was to examine the effectiveness of a short-term leg strengthening exercise program compared to attention control on improving leg strength, walking speed and endurance, physical performance, and physical function one year after hip fracture.

Detailed Description

Poor functional outcomes are reported for the majority of older adults who sustain a hip fracture. The ability of hip fracture patients to make sustained functional improvements above and beyond natural recovery is unknown. It has been shown that gym-based programs can help old adults regain function after hip fracture. It is unclear if these results could be translated into the home setting that lacks the gym-based equipment, or if improvement would be sustainable. This program compares high intensity strength training performed in the home twice weekly for 10 weeks to an attention placebo control in which participants receive sensory electrical stimulation to leg muscles.
