Association between Pain Intensity, Pain Belief, and Coping Strategies in Older Adults.

This study aimed to determine the relation between pain, pain belief, and coping strategies and the interaction effect of pain belief and coping stretegies on pain intensity in older adults living in Denizli. 601 older adults (68.32 ± 8.28 years) with good cognitive function participated in current study. Pain intensity, pain beliefs and coping strategies were assessed with Geriartric Pain Measure (GPM), Pain Beliefs Scale (PBS) and Pain Coping Inventory (PCI), respectively. Mean pain intensity of older adults was 53.6 ± 21 (0-99.96). There was a statistically significant difference in passive coping strategies between older adults with mild, moderate, and severe pain (p < .001). As organic pain belief and active coping strategies increase, the pain intensity decreases in older adults living in Denizli.

Effect of Superimposed Russian Current on Quadriceps Strength and Lower-Extremity Endurance in Healthy Males and Females.

CONTEXT: More studies are needed to compare the effect of voluntary contraction, electrical stimulation, and electrical stimulation superimposed onto voluntary contraction in improving trained and untrained homolog muscle strength and lower-extremity endurance. DESIGN: Seventy-six healthy young adults (age = 20.41 [3.07] y, 61 females and 15 males) were included in the study. Subjects were randomly divided into 3 groups as voluntary isometric contraction (IC) group, Russian current (RC) group, and superimposed Russian current (SRC) group. METHODS: All training regimens were performed under physiotherapist supervision for a total of 18 sessions (3 times per week for 6 wk). In each session, 10 ICs were achieved with voluntary isometric exercise only, RC only, or RC superimposed onto ICs. Main outcome measures were trained and untrained quadriceps strength (maximal voluntary isometric contraction [MVIC]) and lower-extremity endurance (sit-to-stand test). RESULTS: After 6 weeks of training, all outcome measures improved in all groups (P < .05), except the untrained quadriceps MVIC score of RC group (P = .562). The trained quadriceps MVIC score (P < .001, η2 = .478), untrained quadriceps MVIC score (P = .011, η2 = .115), and sit-to-stand test score (P < .001, η2 = .357) differed significantly among the 3 groups; post hoc analysis revealed that the trained quadriceps MVIC score was higher in SRC and RC groups than in the IC group, untrained quadriceps MVIC score was higher in SRC group than in the RC group, and sit-to-stand test score was higher in SRC group than in the RC group and IC group. CONCLUSIONS: RC and RC superimposed onto IC are superior to IC in improving quadriceps muscle strength, and RC superimposed onto IC is superior to RC and IC in improving lower-extremity endurance. RC superimposed onto IC and voluntary IC created cross-education effect on untrained quadriceps.
