Overall recovery was calculated as the sum of recovery on the five separate items, with the overall recovery score ranging from 0 (no recovery on all five items) to 5 (recovered on all five mobility items). The correlation coefficients of grip strength with knee extension strength and quadriceps strength in elderly women are reported to be higher than 0.5 (13)(14). These subjects were followed up during 1 year and were part of a larger project on postfracture changes in bone, muscle, and function. Darrell McIndoe and Arthur Serpick. In fact, sometimes, the pain you experience is even worse than what you were experiencing before undergoing the surgery. Among the subgroup of women (n = 74) who were also measured at a 6-month follow-up, there was no significant association between the short-term change (from baseline to 6-month follow-up) in muscle mass or muscle strength and the short-term change in mobility function ( p > .2). Ankle dorsiflexion strength was measured three times using a Spark hand-held dynamometer (Model 160, Spark Instruments and Academics, Inc., Iowa City, IA). Grip strength and ankle dorsiflexion strength were used as indicators of muscle strength and were measured at baseline and at 12-month follow-up. Although you’ll likely be functioning well 4 to 6 months after your surgery, weakness in the muscles surrounding your hip may persist for up to 2 years. The five individual items were summed to create an overall mobility function score ranging from 0 (independent on all five mobility items) to 10 (unable to perform all of the five mobility items). In this analysis, the change in mobility function score was also associated with chronic disease (women with more chronic illnesses at baseline were less likely to decline in mobility function; p = .03), the number of days in the hospital (women who stayed in the hospital longer were more likely to decline in mobility function; p = .04), and hip pain (those with hip pain tended to have a greater decline in mobility function; p = .07). Hip flexor strain can occur when the hip flexor muscles are pulled, strained, torn or injured. The surgery can correct the hip problem, but the muscles will remain weak and will only be strengthened through regular exercise. Although the overall change in leg muscle mass and grip strength from baseline to 12-month follow-up was not significant, the variability in the change was high, which indicates the presence of different patient subgroups.

Overall mobility recovery was calculated as the sum of the individual recovery scores of the five mobility items. It is normal for your leg muscles to atrophy (shrink) before and after joint replacement surgery. Patients were always measured on the same DXA machine. For each mobility item, the percentage of women who were able to perform the item independently decreased after the fracture, and the percentage of women who were unable to perform the item increased after the fracture. The overall mobility score was calculated for each tertile of muscle mass change and muscle strength change (Table 4 ). Loss of muscle mass has been hypothesized to be associated with impaired physical function because both loss of muscle and poorer physical function are age related (20)(21). Analysis of covariance was used to assess the association between tertiles of muscle mass change, or tertiles of muscle strength change, and the mobility function outcomes, adjusting for potential confounders. During hip replacement surgery, the nerves in the leg, including the sciatic nerve, can sometimes be stretched or damaged. At follow-up, only 17.8% of the women had returned to their prefracture level of mobility function for all five items. The top of your femur is shaped like a ball and covered with cartilage. No interaction between change in muscle strength and any of the potential confounders was observed. 3  When your gluteus medius muscle becomes weak, it allows your thigh to rotate and pull inwards abnormally. Our study suggests that specific strength training might increase the chance for full mobility recovery, in addition to usual modes of physical therapy. It is normal for muscles to feel sore or shaky when starting a new exercise 2. In a small 2012 study, researchers had one group perform regular exercises after hip replacement surgery while a second group performed more intense exercises using resistance bands. There were no differences in mobility recovery by level of muscle mass change after hip fracture, even after adjustment for baseline characteristics and hip pain. Even if you consider yourself an active person and do yoga #everydamnday, chances are you also spend a lot of time sitting. Body composition was measured using dual-energy x-ray absorptiometry (DXA) (models QDR-1000W and QDR-1500, Hologic, Inc., Waltham, MA). The maximum strength result (in kilograms) of the two trials of the nonfractured leg was used. The femoral cutaneous nerve was either damaged or injured because I did have to have a total hip revision 3 weeks after first hip replacement due to dislocation. Continue with these exercises for at least the first year after your surgery The present study examined whether mobility recovery after hip fracture was related to change in appendicular skeletal muscle mass or to change in muscle strength. Data on grip strength and ankle dorsiflexion were available for 71 and 69 women, respectively. Clench your butt at the top of the movement, pause, and lower back down. Tight muscles in the buttocks and hip. Raise your hips to form a straight line from your shoulders to your knees (use a support if needed). However, an underestimation of muscle mass loss may have been caused by several factors. The results show that elderly women who lose muscle mass have a similar recovery of mobility function after the fracture compared with women who did not change or who gained muscle mass. Symptoms of inclusion-body myositis typically begin after age 50 with very gradual weakening of muscles throughout the body. Marjolein Visser, Tamara B. Harris, Kathleen M. Fox, William Hawkes, J. Richard Hebel, Janet YuYahiro, Roger Michael, Sheryl Itkin Zimmerman, Jay Magaziner, Change in Muscle Mass and Muscle Strength After a Hip Fracture: Relationship to Mobility Recovery, The Journals of Gerontology: Series A, Volume 55, Issue 8, 1 August 2000, Pages M434–M440, https://doi.org/10.1093/gerona/55.8.M434. Methods. The change in arm muscle mass and ankle dorsiflexion strength were statistically significant ( p < .01). Some people say their legs feel like rubber or jelly when their leg strength is diminished. Values ranged from 0 to 5. Weak leg muscles can make it difficult to walk or stand. Moreover, several validation studies that used changes in total body water during dialysis to simulate changes in total body lean mass of only 2%–4% have shown good results (33)(34). You may develop dysphagia, weak wrists or fingers, and atrophy of the forearms and/or thigh muscles. A similar threshold may exist for muscle mass, and the community-dwelling women included in our study might still be above that threshold after the fracture. Nelson ME, Fiatarone MA, Layne JE, et al. Unlike other forms of myositis, inclusion-body myositis occurs more often in … Your leg should be lifted out and to the side of your body with your knee straight. Future intervention studies should include strength measurements of different muscle groups to confirm our findings and to contribute to the development of optimal rehabilitation programs after a hip fracture. Ninety community-dwelling women aged 65 years and older who had recently experienced a fracture of the proximal femur were included in the study. The overall mobility score increased from 2.31 ± 1.86 prefracture to 4.08 ± 2.35 12 months after the fracture ( p = .0001). First, the change in leg muscle mass could only be studied in the nonfractured leg because of the swelling of the fractured leg. In rare cases, a malpositioned hip prosthesis implant can cause a limp after hip replacement surgery. So these muscles, then, are weak in someone with osteoarthritis of the hip joint. After adjustment for potential confounders, women in tertile I had a greater decline in mobility function (2.45, SE = 0.35) compared with women in tertile III (1.13, SE = 0.36, p = .012) and tended to have a greater decline compared with women in tertile II (1.45, SE = 0.35, p = .052). Mobility function recovery was not related to change in skeletal muscle mass of the nonfractured leg or the arms. Participants were categorized by tertile of nonfractured leg muscle mass change from baseline to month 12 (cutoff points <−3.3%, −3.3% to +5.5%, >+5.5%); by tertile of arm muscle mass change (cutoff points <−11.6%, −11.6% to 0, >0); by tertile of change in grip strength (cutoff points <−9.2%, −9.2% to +8.3%, >8.3%); and by tertile of change in ankle dorsiflexion strength of the nonfractured leg (cutoff points <0, 0 to +23.0%, >+23.0%). The observed net change in skeletal muscle mass was rather small. Surgery corrected the hip problem. To detect possible drift over time, quality control of the DXA machines was performed every day prior to scanning patients by using an anthropomorphic spine phantom. The success has been remarkable. However, currently no empirical evidence supports a direct causal relationship between muscle mass and disability, even though low muscle mass has been associated with lower bone mineral density (22)(23) and may be a predictor of falls.

Among the 74 women who had additional measurements of body composition and mobility function at the 6-month follow-up, the association between short-term change in muscle mass and muscle strength with short-term change in mobility function was investigated. At 2 to 10 days after hospital admission, the women's grip strength, ankle dorsiflexion strength, and regional muscle mass (by dual-energy x-ray absorptiometry) were measured, and the prefracture level of independence for five mobility function items was assessed. It is important to try to keep your swelling down after surgery. Thirteen (14.4%) women were fully independent on all five mobility items before the fracture, whereas only two (2.2%) women were fully independent 12 months after the fracture. You will be able to do this by: 1. lying flat with your leg at the level of your heart 2. putting a cold pack on your hip 3. actively pumping your muscles through ankle pumps 4. balancing activity with rest 5. Note: A higher mobility function score indicates greater dependency. Hip replacement surgery is very effective at reducing or eliminating hip joint pain and improving hip joint function. Adjusted for age, body fatness, chronic illness, cognitive status, days hospitalized, and hip pain at 2 months. I am 48 and had a full hip replacement on Dec 27,2017 as an outpatient procedure. In fact, clinical trial data from growth hormone trials show increases in muscle mass but no improvement in functional ability (24). A measure of comorbidity was created using history of chronic conditions reported in the medical chart as present at the time of fracture, including joint disease (arthritis, rheumatism, or degenerative joint disease), heart disease (angina, arrhythmias, chronic heart failure, or other heart problems), diabetes mellitus, cancer (cancer, leukemia, or malignancy), and stroke. Indeed, a greater loss of muscle mass was observed in the arms compared with the nonfractured leg. Only the results for leg muscle mass of the nonfractured leg were used in the analyses to eliminate bias that might occur with the swelling of soft tissue around the fracture site. Skeletal Muscle Mass Assessed by Dual-Energy X-ray Absorptiometry and Muscle Strength in Elderly Women at Baseline and 12 Months After a Hip Fracture, Characteristics of Elderly Women Before and 12 Months After Hip Fracture by Tertile of Muscle Mass Change from Baseline to 12 Months (mean ± SD), Characteristics of Elderly Women Before and 12 Months After Hip Fracture by Tertile of Muscle Strength Change from Baseline to 12 Months (mean ± SD), Change in Overall Mobility Function Score 12 Months After Hip Fracture in Elderly Women by Tertile of Muscle Mass Change and by Tertile of Muscle Strength Change from Baseline to 12 Months.
