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.

Condition or disease Intervention/treatment Phase
Hip Fractures Other: progressive resistance exercise Other: TENS Phase 1 Phase 2

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.

Arm Intervention/treatment
Experimental: Exercise
High intensity lower extremity exercise
Other: progressive resistance exercise
lower extremity strengthening: 3 sets of 8 repetitions at the 8 repetition maximum (8RM)for the hip and knee extensors, hip abductors, plantarflexors twice weekly for 10 weeks.
Other Name: strengthening exercise
Sham Comparator: Attention control
lower extremity TENS
Other: TENS
Transcutaneous electrical nerve stimulation (TENS) to elicit sensory information (comfortable tingling) for 7 minutes to bilateral muscle groups including the gluteal muscles, quadriceps, and gastroc-soleus muscles. TENS administered twice weekly for 10 weeks.

Primary Outcome Measures :
  1. lower extremity force production [ Time Frame: one year after hip fracture ]

Secondary Outcome Measures :
  1. six minute walk distance [ Time Frame: one year post fracture ]
  2. free and fast gait speed [ Time Frame: one year post fracture ]
  3. modified physical performance test [ Time Frame: one year post fracture ]
  4. SF-36 physical function [ Time Frame: one year post fracture ]
