These are large, full-range movements of one or more joints at once, often performed standing and sometimes while walking or jogging. They resemble old-school movements you might have done in calisthenics or gym class: arm swings, leg swings, high-knee walks. You usually count off reps, rather than time, on dynamic stretches, which work best as a warm-up activity before a workout, or any time you need a pick-me-up boost throughout the day.
A vertebral compression fracture in the spine occurs when one or more vertebra become smashed or compressed. This injury is typical in individuals with osteoporosis and the elderly and can be caused by severe trauma to the back as well, such as in a car accident or following a fall. Symptoms include a sudden popping sound in the back and pain in the back. Treatment may include rest, wearing a back brace, or procedures such as vertebroplasty.
Don’t medically investigate back pain until it’s met at least three criteria: (1) it’s been bothering you for more than about 6 weeks; (2) it’s severe and/or not improving, or actually getting worse; and (3) there’s at least one other “red flag” (age over 55 or under 20, painful to light tapping, fever/malaise, weight loss, slow urination, incontinence, groin numbness, a dragging toe, or symptoms in both legs like numbness and/or tingling and/or weakness).
How to: Get in a standing position, with one foot about a foot's distance behind the other, hips in line. Your feet should be flat, and your legs should be straight. Cross the back foot behind the front one as you reach your arm on the same side overhead. Return to starting position. That's one rep. Do eight reps on each side. Do three to four sets before moving on to the next move, resting for 30 seconds in between each set.
Gait analysis studies in the elderly show that they typically have a shortened step length. Whether that is a result of tight hip flexors or due to reduced balance, the propensity to walk with shorter steps will itself lead to tightness in hip flexors and anterior joint structures. Hip stretches may be a relatively easy preventative strategy for the elderly with gait abnormalities and may help to prevent falls.
You're more likely to get a hip flexor injury if you've had one in the past, you don't warm up properly before engaging in athletic activity, your muscles are already tight or stiff, or your muscles are weak from being overused. If, while exercising, you try to do too much at once in too short an amount of time, you can also put yourself at risk for a hip flexor injury.
