This review looked at how muscle strength affects movement in older adults who have suffered a hip fracture. The researchers found that specific muscles play different roles in stability. For example, weak hip abductor muscles are linked to pelvic instability, while calf and gluteus maximus weakness are associated with shorter strides and less power when walking.
Another finding showed that weakened quadriceps are linked to knee instability and limited movement of the leg. These issues can lead to an uneven walking style. The review also noted that many patients experience a rapid decline in muscle strength after a fracture, followed by a slow recovery over the first six months. Even then, some muscle levels may stay below normal for a long time.
Because these physical changes often last for one to two years after surgery, rehabilitation is important. The review suggests that training programs focused on specific muscle groups could help patients regain their strength and reduce the risk of falling. However, this was a narrative review of existing information, not a clinical trial testing a specific new exercise program.
