Effects of Anteroposterior Talus Mobilization on Range of Motion, Pain, and Functional Capacity in Participants With Subacute and Chronic Ankle Injuries: A Controlled Trial.

Objective: The purpose of this study was to measure the acute (1 session) and chronic effects (6 sessions) and the follow-up (2 weeks) of anteroposterior articular mobilization of the talus, grade III of Maitland, on the dorsiflexion range of motion (ROM), pain, and functional capacity of individuals with subacute and chronic traumatic injuries of the ankle.

Methods: Thirty-eight volunteers, men and women, with a mean age of 40.8 years, with subacute and chronic ankle injuries participated.

Translation, cross-cultural adaptation and validity of the Brazilian version of the Foot and Ankle Ability Measure questionnaire.

Purpose: To translate and cross-culturally adapt the Foot and Ankle Ability Measure (FAAM) questionnaire and verify the psychometric properties of the Brazilian-Portuguese version of this instrument.

Methods: Analysis of validity was carried out by applying the Rasch model and evaluating correlations with the Short Form-36 (SF-36) Physical Function (PF) subscale. Test-retest reliability and internal consistency were analyzed with the intraclass correlation coefficient (ICC2,1) and Cronbach's alpha tests, respectively.

Immediate effect of a single anteroposterior talus mobilization on dorsiflexion range of motion in participants with orthopedic dysfunction of the ankle and foot.

Objective: The purpose of this study was to determine the immediate effects of a single anteroposterior mobilization of the talus on the active dorsiflexion range of motion (ROM) in participants with different orthopedic foot and ankle injuries.

Methods: This study included 30 male and female participants aged 18 to 50 years with unilateral orthopedic foot and ankle dysfunction. All participants underwent 3 sets of active dorsiflexion ROM measurement in both ankles.

Effect of transcutaneous electrical stimulation on nociception and edema induced by peripheral serotonin.

Transcutaneous electrical nerve stimulation (TENS) is defined as the application of an electrical current to the skin through surface electrodes for pain relief. Various theories have been proposed in order to explain the analgesic mechanism of TENS. Recent studies have demonstrated that part of this analgesia is mediated through neurotransmitters acting at peripheral sites.

Blockade of opioid receptors in the medullary reticularis nucleus dorsalis, but not the rostral ventromedial medulla, prevents analgesia produced by diffuse noxious inhibitory control in rats with muscle inflammation.

Unlabelled: Diffuse Noxious Inhibitory Controls (DNIC) involves application of a noxious stimulus outside the testing site to produce analgesia. In human subjects with a variety of chronic pain conditions, DNIC is less effective; however, in animal studies, DNIC is more effective after tissue injury. While opioids are involved in DNIC analgesia, the pathways involved in this opioid-induced analgesia are not clear.

Force-displacement relationship during anteroposterior mobilization of the ankle joint.

Objective: The purpose of this study was to determinate the correlation between force and displacement during passive anteroposterior mobilization of the talus and the effect of this treatment technique on ankle dorsiflexion range of motion (ROM).

Methods: This is an exploratory, methodological study. Maitland grades III and IV mobilization were applied on the right ankle of 25 healthy subjects (mean age +/- standard deviation, 25.

Study of the force applied during anteroposterior articular mobilization of the talus and its effect on the dorsiflexion range of motion.

Objective: The aim of this study was to investigate the behavior of the force applied during the Maitland grade III anteroposterior joint mobilization of the talus and its effect on dorsiflexion range of motion (ROM).

Methods: Two examiners performed measurements of dorsiflexion ROM on both ankles of healthy volunteers using a universal goniometer. The anteroposterior talus mobilization was first applied by examiner A for 30 seconds.

Release of endogenous opioids following transcutaneous electric nerve stimulation in an experimental model of acute inflammatory pain.

Unlabelled: Transcutaneous electric nerve stimulation (TENS) is a noninvasive treatment used in physiotherapy practice to promote analgesia in acute and chronic inflammatory conditions. The aim of the present study was to investigate the action mechanism of TENS at high (HF: 130 Hz) and low (LF: 10 Hz) frequencies in an inflammation model produced by the injection of carrageenan in rat paws (Cg; 250 microg). After carrageenan administration (0 time), either HF or LF TENS was applied to the inflamed paw of rats for 20 minutes, and hyperalgesia was assessed hourly using the modified Randall-Selitto method (1957).

Local transcutaneous electrical stimulation (TENS) effects in experimental inflammatory edema and pain.

Few studies in the literature associated transcutaneous electrical stimulation (TENS) use with an antiinflammatory activity. The purpose of this study was to investigate the effects of low (10 Hz)- and high (130 Hz)-frequency TENS on hyperalgesia and edema that occur after injection of carrageenan in rat paw. After induction of inflammation, either low- or high-frequency TENS was applied in the rat paw for 20 min, and the effect of TENS treatment on escape or paw withdrawal and edema was measured.
