“…We hypothesize that FM patients had a lower speed of finger tapping task than controls due to the interaction of several factors linked to pain condition. Moreover, studies focused on motor ability suggest that FM patients had low manual dexterity [41] and minor handgrip strength [13] compared to healthy subjects. In a study on the evaluation of the kinematic parameters of gait and balance, patients with FM showed impaired motor performance [40].…”

“…Researchers suggest that motor activity leads to an improvement in the quality of life of patients [11,12] so exercise is recommended for the treatment of FM symptoms. Moreover, FM patients have a peculiar limitation of movement that can manifest itself with dysfunctions in muscle coordination, difficulty in postural control and reduced speed of motor performance [13,14]. However, patients suffering from chronic pain are unlikely to exercise because they fear the worsening of their painful condition [15,16].…”

Mutual interaction between motor cortex activation and pain in fibromyalgia: EEG-fNIRS study

Background Experimental and clinical studies suggested an analgesic effect on chronic pain by motor cortex activation. The present study explored the complex mechanisms of interaction between motor and pain during performing the slow and fast finger tapping task alone and in concomitant with nociceptive laser stimulation. Method The participants were 38 patients with fibromyalgia (FM) and 21 healthy subjects. We used a simultaneous multimodal method of laser-evoked potentials and functional near-infrared spectroscopy to investigate metabolic and electrical changes during the finger tapping task and concomitant noxious laser stimulation. Functional near-infrared spectroscopy is a portable and optical method to detect cortical metabolic changes. Laser-evoked potentials are a suitable tool to study the nociceptive pathways function. Results We found a reduced tone of cortical motor areas in patients with FM compared to controls, especially during the fast finger tapping task. FM patients presented a slow motor performance in all the experimental conditions, requesting rapid movements. The amplitude of laser evoked potentials was different between patients and controls, in each experimental condition, as patients showed smaller evoked responses compared to controls. Concurrent phasic pain stimulation had a low effect on motor cortex metabolism in both groups nor motor activity changed laser evoked responses in a relevant way. There were no correlations between Functional Near-Infrared Spectroscopy (FNIRS) and clinical features in FM patients.

“…The association between FM and reduced HGs has been demonstrated in different contexts 38,41,42 . Discordant data also exist, in which no associations between FM severity and reduced muscle performance, expressed in terms of isokinetic flexion-extension of the knee, has been demonstrated 43 .…”

The aim of this study was to compare the handgrip strength (HGs), assessed with a cylindrical-shape grip device, of fibromyalgia syndrome (FM) patients with healthy subjects and to demonstrate the relationship between HGs characteristics and disease severity. Consecutive female patients with FM were enrolled and compared to a group of healthy women. The correlations between HGs curve characteristics and disease severity indices were studied through the Spearman's rho correlation coefficients (rho). The HGs threshold distinguishing the FM presence was determined using the receiver operating characteristic (ROC) curves analysis. Multivariate regression analysis was used in order to assess the contribution of covariates on the HGs. 110 patients (mean age 53.8 ± 12.4 years) and 111 healthy controls have been enrolled. Altogether all parameters related to the analysis of HGs were worse in patients with FM. The HGs cut-off distinguishing the presence of a FM was 14.2 Kg. A negative correlation was found between disease severity indices and peak force (p < 0.001). Factors significantly associated with HGs area under the curve (AUC) in multivariate analysis were the Widespread Pain Index (WPI) (p = 0.003) and the revised Fibromyalgia Impact Questionnaire (FIQR) (p = 0.016). HGs is reduced in female FM patients and is inversely related to disease severity. The force-time curves analysis may be used as a complementary tool in the FM assessment and monitoring.Fibromyalgia syndrome (FM) is a multi-symptom disorder, characterized mainly by chronic widespread musculoskeletal pain, chronic fatigue, sleep disturbance, symptoms of cognitive impairment, and activity limitations, the etiology of which is still to be clarified 1 .The physical fitness is globally reduced over the course of FM and under this term are included multiple domains, in particular muscle strength, aerobic activity, balance and flexibility: the limitations of one or more of these aspects determine a functional limitation 2,3 . Adequate muscle strength is obviously necessary to perform all the usual actions of daily life 4-6 . In female patients with FM, a strength deficit of 20% to 36% is documented compared to healthy women 7 . The reduction in muscle strength in women with FM results in a deterioration in the quality of life (QoL) 8 .Handgrip strength (HGs), as a substitute for overall muscle strength, is related to physical fitness 9,10 . HGs is traditionally measured as the maximum force that can be generated by each hand. This parameter is used to assess the degree of hand deterioration in the FM. However, peak force measurement alone does not take into account other hand strength characteristics such as force generation speed, sustainability, and grip force variability.A more accurate description of HGs is certainly provided by the force-time (FeT) curve analysis. The FeT curve can be used to assess effort sincerity and distinguish between sincere effort and false weakness 11 . Through the analysis of the FeT curve it is possible to reveal peak force, m...

“…The patients had lower grip strength, performed lesser repetitions with maximal grip pressure (dynamic endurance work), and kept their upper extremity in a fixed position for a lesser duration (static endurance work) as compared to the healthy matched controls. Köklü et al 23 reported that FMS patients had decreased handgrip strength as compared to the controls. Contrary to these studies, Akyol et al 19 did not find any difference between the FMS patients and healthy controls regarding handgrip strength.…”

Objectives: This study aims to evaluate wrist muscle strength and muscle fatigue in females with fibromyalgia syndrome (FMS) and compare the results with those of healthy controls. Patients and methods: Thirty consecutive female FMS patients (mean age 39.8±6.7 years; range 25 to 49 years) and 50 age and body mass index similar healthy females (mean age 35.4±7.9 years; range 27 to 48 years) were enrolled. Patients' clinical characteristics were recorded and symptoms were evaluated by the Fibromyalgia Impact Questionnaire. In addition to the demographic characteristics, physical activities of all subjects were questioned, isokinetic muscle performance was measured, and fatigue index was calculated by endurance test. Results:The peak torque values of the wrist extensor and flexor muscles (at an angular velocity of 90°/second) were higher in the control group than in the FMS group (both p<0.01). There were no differences between the groups in terms of the fatigue indexes of the flexor and extensor muscles of the wrist (both p>0.05). While there were differences between the groups regarding weekly hours of walking (p=0.01) and house cleaning (p<0.001), no differences were determined for weekly hours of bicycling, gardening, doing sports, or total physical activity. There was no correlation between the peak torque values and clinical characteristics in FMS group. Conclusion: Patients with FMS had decreased muscle strength compared to healthy controls. Further studies with larger participants are needed to explain the relationship between upper limb muscle performance and FMS, as well as the underlying pathogenesis.
