Inter-rater Accuracy and Reliability of a Palpation Protocol of the C7 Spinous Process Comprising a Combination of 3 Traditional Palpation Techniques.

OBJECTIVE: The purpose of this study was to determine the accuracy and intrarater reliability of a palpatory protocol based on a combination of 3 palpatory methods to identify both the C7 spinous process (C7 SP) and the factors that affect the errors and inaccuracy of palpation. METHODS: Twenty-five women between the ages of 18 and 60 years were submitted to a palpation protocol of the C7 SP, and a radiopaque marker was fixed on the skin at the possible location of the vertebrae. A radiograph and a photograph of the cervical spine were obtained in the same posture by a first rater. A second rater performed the same palpation protocol and took a second photograph. The accuracy and measurement error of the palpation protocol of C7 SP were assessed through radiographic images. The inter-rater reliability was estimated by the interclass correlation coefficient and assessed using photographs of each rater. The Pearson's correlation coefficients (r), the Fisher exact test, and the χ2 test were used to identify the factors associated with the error and inaccuracy of palpation. RESULTS: Accuracy of the C7 palpation was 76% with excellent reliability (interclass correlation coefficient = 0.99). There was a moderate correlation between weight and the measurement of palpation error (r = -0.6; P = .003). One hundred percent of inaccuracy palpation was related to the increased soft-tissue thickness (P = .005) in the cervical region. CONCLUSION: The palpation protocol described in this study was accurate and presented excellent reliability in identifying the C7 SP. Increased weight and dorsocervical fat pad were associated to error and palpation inaccuracy, respectively.

Hippotherapy as a treatment for socialization after sexual abuse and emotional stress.

[Purpose] Hippotherapy is a therapeutic resource that uses the horse as a kinesiotherapy instrument to elicit motor and cognitive improvements in individuals with special needs. [Subjects and Methods] This research evaluated two women aged 18 and 21 years, who had suffered sexual violence when they were children between the ages of 6 and 7 years old. The subjects did not have mental dysfunction but they were regular students registered at a school of special education. The patients presented severe motor limitation, difficulty with coordination, significant muscular retractions, thoracic and cervical kyphosis, cervical protrusion wich was basically a function of the postures they had adopted when victims of the sexual violence suffered in childhood. The patients performed twenty sessions of 30 minutes of hippotherapy on a horse. The activities were structured to stimulate coordination, proprioception, the vestibular and motor-sensorial systems for the improvement of posture, muscle activity and cognition. [Results] The activities provided during the hippotherapy sessions elicited alterations in postural adjustment resulting in 30% improvement, 80% improvement in coordination in, 50% improvement in corporal balance and in sociability and self-esteem. [Conclusion] Hippotherapy proved to be an effective treatment method for coordination, balance and postural correction, and also improved the patients' self-esteem that had suffered serious emotional stress.

Influence of ultrasound and physical activity on bone healing.

The aim of this study was to investigate the effects of ultrasound treatment of experimental bone fractures and the effects of physical exercise on the speed of bone consolidation. Osteotomy was performed on the upper third of the right tibia of rats. Physical training consisted of swimming 1 h per d with a load of 5% body weight and therapy with medium-intensity ultrasound was applied for 5 min daily. Young adult male Wistar rats were divided into four groups: (1) osteotomized sedentary animals with no ultrasound treatment (OSnUS); (2) trained with no ultrasound treatment (OTnUS); (3) sedentary with ultrasound treatment (OSwUS); and (4) trained with ultrasound treatment (OTwUS). The animals were sacrificed for the following analyses: muscle glycogen and serum alkaline phosphatase on the 5th, 10th, 20th and 30th days and histological slices of the bone on the 5th and 20th days. The results show that ultrasound is better in the initial phases of the process of bone tissue repair and physical exercise at the end of bone consolidation. These facts suggest that the treatments herein used prove favorable to the bone regenerative process, as the overall ossification process has been accelerated.
