“…Dal et al [ 8 ] reported similar oxygen cost and consumption for both the FS and control subjects during walking at self selected walking speeds. This may have been due to the slower self selected walking speeds adopted by the FS subjects relative to matched controls.…”

“…This may have been due to the slower self selected walking speeds adopted by the FS subjects relative to matched controls. Dal et al suggested that the FS subjects were compensating for the pathology in their gait and that the Borg Scale of Perceived Exertion measures were higher in the FS subjects relative to controls despite slower walking speeds [ 8 ].…”

“…These differences did not result in significant differences in oxygen consumption or energy expenditure at matched slow or faster walking speeds. Although various other clinical populations have reported greater energy expenditure due to altered gait mechanics, such findings are not universal [ 16 ] and at least one other study has reported a lack of difference in energy expenditure at self selected walking speeds between FS and control subjects [ 8 ] Hence, altered gait mechanics in women with FS may not account for the increased fatigue expressed by the subjects with FS based on any significant differences in energy expenditure or higher levels of oxygen consumption. Therefore increased daily fatigue in women with FS relative to controls may not be related to differences in energy expenditure while walking.…”

Metabolic cost and mechanics of walking in women with fibromyalgia syndrome

BackgroundFibromyalgia syndrome (FS) is characterized by the presence of widespread pain, fatigue, muscle weakness and reduced work capacity. Previous research has demonstrated that women with fibromyalgia have altered walking (gait) patterns, which may be a consequence of muscular pain. This altered gait is characterized by greater reliance on hip flexors rather than ankle plantar flexors and resembles gait patterns seen in normal individuals walking at higher speeds, suggesting that gait of individuals with fibromyalgia may be less efficient.This study compared rates of energy expenditure of 6 females with FS relative to 6 normal, age and weight matched controls, at various walking speeds on a motorized treadmill. Metabolic measurements including V02 (ml/kg/min), respirations, heart rate and calculated energy expenditures as well as the Borg Scale of Perceived Exertion scale ratings were determined at baseline and for 10 min while walking at each of 2, 4 and 5 km/hour on 1% grade. Kinematic recordings of limb and body movements while treadmill walking and separate measurements of ground reaction forces while walking over ground were also determined. In addition, all subjects completed the RAND 36-Item Health Survey (1.0).FindingsGait analysis results were similar to previous reports of altered gait patterns in FS females. Despite noticeable differences in gait patterns, no significant differences (p > 0.05) existed between the FS and control subjects on any metabolic measures at any walking speed. Total number of steps taken was also similar between groups. Ratings on the Borg Scale of Perceived Exertion, the RAND and self-reported levels of pain indicated significantly greater (p < 0.05) perceived effort and pain in FS subjects relative to control subjects during walking and daily activities.ConclusionsThe altered gait patterns and greater perceptions of effort and pain did not significantly increase the metabolic costs of walking in women with FS and hence, increased sensations of fatigue in FS women may not be related to alteration in metabolic cost of ambulation.

“…The determination of PWS, energy expenditure measurements and data analysis methods were explained in detail in one of our previous study. 18 For the energy expenditure measurements of walking, subjects were asked to walk at PWS and 30% above PWS on the a motor-driven treadmill at 0% grade for 7 min. Previous studies in our laboratory have shown that the speed 30% above PWS was not forced the subject to run, but it was more intense walking than PWS.…”

ObjectiveThe aim of this study was to determine the alterations of walking energy expenditure and plantar pressure distribution in young adults with patellofemoral pain syndrome (PFPS).MethodsThirty five individuals (mean age: 21.31 ± 1.76) with PFPS constituted the patient group and forty healthy participants (mean age: 21.40 ± 2.11) the control group. Preferred walking speeds (PWS) were determined on the over ground. Individuals walked on a treadmill for 7 min at their PWS and 30% above PWS and oxygen consumption was recorded via a metabolic analyzer. Net oxygen consumption was calculated for each walking trial. Borg scale was applied to assess perceived exertion during walking trial. Plantar pressure distributions were measured by a pedobarography device. Plantar area was subdivided into six zones to evaluate the dynamic plantar pressure data.ResultsThe mean PWS of PFPS and control groups were 4.69 ± 0.51 and 4.52 ± 0.60 km/h, respectively (p > .09). No significant difference was observed in energy expenditure during walking at PWS between 2 groups while oxygen consumption during 30% above PWS was higher in patient group (18.72 ± 3.75 and 16.64 ± 3.27) (p = .007). Net oxygen consumption was also found to be higher in PFPS group (15.12 ± 3.62 and 13.04 ± 3.24) (p = .005). The mean Borg scores were significantly higher in PFPS group at each walking trials (p < .001). No statistically significant difference was found between weight distribution (%) of symptomatic and nonsymptomatic extremity (50.45 ± 3.92% and 49.56 ± 3.93%, respectively) (p = .509). Dynamic pedobarography parameters were not different between 2 groups, and also between symptomatic and nonsymptomatic extremities (p > .05).ConclusionAlthough, rate of perceived exertion and energy expenditure during walking at 30% above PWS are affected negatively in young adults with PFPS, we may speculate that energy consumption and plantar pressure distribution can be compensated by a physiologic adaptation mechanism during walking at PWS.Level of evidenceLevel III, Therapeutic Study.

The evidence (rated as low quality) suggested that moderate- and moderate- to high-intensity resistance training improves multidimensional function, pain, tenderness, and muscle strength in women with fibromyalgia. The evidence (rated as low quality) also suggested that eight weeks of aerobic exercise was superior to moderate-intensity resistance training for improving pain in women with fibromyalgia. There was low-quality evidence that 12 weeks of low-intensity resistance training was superior to flexibility exercise training in women with fibromyalgia for improvements in pain and multidimensional function. There was low-quality evidence that women with fibromyalgia can safely perform moderate- to high-resistance training.
