Preliminary Evidence of Altered Biomechanics in Adolescents With Juvenile Fibromyalgia

The Results (Physical and Psychosocial Functioning; page unavailable) report marked fear of movement in adolescents with juvenile fibromyalgia. The Discussion (page unavailable) describes a possible cycle of pain-related fear, activity avoidance, disability, and pain, but does not establish that kinesiophobia arises from an association between pain, fatigue, and movement. The claim also states the activity and pain consequences more definitively than the paper does. (LLM, conf=0.86)

The Results (Biomechanical and Biodynamic Assessments; page unavailable) report shorter self-selected strides in adolescents with juvenile fibromyalgia, but no significant difference in walking speed. The paper does not report delayed gait initiation or altered postural sway, and its adolescent findings do not establish those claims for FM patients generally. Muscle activation patterns are attached to a separate citation in the citing sentence. (LLM, conf=0.90)

The passage labeled Abstract > Conclusions recommends moderate-to-vigorous activity and muscle-strengthening exercises at least twice weekly for pain management in juvenile fibromyalgia. The citing sentence attributes the exercise recommendation to this source, but broadens the population to FM generally and substitutes weight-bearing exercises for muscle strengthening. Its separate claim about poor adherence is attached to other citations. (LLM, conf=0.84)

The Discussion (page not provided) describes decreased trunk flexion and increased hip flexion during landing, and suggests these deficits may indicate reduced proximal stabilization. The paper discusses fall risk in connection with biodynamic deviations generally, but does not establish that all three specified findings contribute to falls; its discussion of these landing findings instead mentions jump height and possible injury risk. (LLM, conf=0.88)

The Results (Sample Characteristics; page unavailable) report that a normal-BMI subgroup showed differences consistent with the full sample, and the Discussion says functional deficits, including altered gait, were evident beyond group differences in BMI. The paper did not report a formal BMI-adjusted analysis or directly assess postural control, and it does not establish a disease-specific mechanism. (LLM, conf=0.88)

The Results report reduced knee and hip strength in adolescents with juvenile fibromyalgia, and the Discussion describes altered knee mechanics during a drop vertical jump. The claim says “FM patients” generally, but this study directly tested adolescents with juvenile fibromyalgia, not FM patients across age groups. (LLM, conf=0.82)

The Discussion (page unavailable) names fear of movement as a possible reason for altered gait in adolescents with juvenile fibromyalgia and reports associations between fear and slower walking, weaker strength, and poorer physical-task performance in adults with other chronic pain conditions. It does not establish that those three factors mediate fear’s effect on gait; the Results (page unavailable) also found no significant difference in self-selected walking speed between the adolescent groups. (LLM, conf=0.84)

The Results report reduced knee and hip strength and altered gait in adolescents with juvenile fibromyalgia. The Discussion links altered mechanics to possible injury risk and reports increased fall risk in adults with fibromyalgia. It does not establish that these factors increase fall-related injuries or fear of falling, or that those outcomes reduce quality of life; its discussion of fear concerns movement and pain. (LLM, conf=0.84)

The Results (Sample Characteristics; page unavailable) report that movement-related deficits persisted in adolescents with juvenile fibromyalgia and controls whose BMI was in the normal range. The Discussion likewise says the deficits were evident beyond group differences in BMI. This bears on whether body mass explains motor-control differences, but the paper does not establish that the literature is mixed about obesity and postural stability. (LLM, conf=0.76)

The introduction (page unavailable) says pain-related fear may reinforce activity avoidance, contribute to functional deficits, and further contribute to physical deconditioning. The Conclusions also link fear of movement to activity avoidance in adolescents with juvenile fibromyalgia. Our copy does not address pain catastrophizing, and it presents these links as possibilities rather than established causal effects. (LLM, conf=0.86)

The Discussion says biomechanical measures can assess whether integrative training improves physical functioning in patients with juvenile fibromyalgia (JFM). The citing sentence extends that proposed use to patients with fibromyalgia generally, while the paper says its findings are specifically relevant to JFM and may not generalize to other conditions. (LLM, conf=0.85)

The Discussion (page unavailable) says that combining integrative neuromuscular training with cognitive-behavioral therapy holds promise for adolescents with juvenile fibromyalgia, and describes tailored movement instruction intended to build confidence and support activity. It does not specify enjoyable exercise or sensory challenges, and its proposed approach is limited to juvenile fibromyalgia rather than fibromyalgia generally. (LLM, conf=0.86)
