The purpose of this investigation was to determine the relationship between personality characteristics, as measured by the Myers-Briggs Type Indicator (MBTI) (form G), and an acute pain response in 107 postadolescent men. Subjects included 107 military school cadets. Each subject performed a cold pressor test (CPT) and was evaluated for pain threshold and pain tolerance times. Each was then evaluated for preference on eight personality characteristics: extraversion, introversion, sensing, intuition, thinking, feeling, judging, and perception. The personality characteristics were measured by the MBT1 (form G). Pearson product-moment correlations between the pain threshold and tolerance times and the eight personality characteristic scores were nonsignificant. The results indicated there was no relationship between the eight personality characteristics, as measured by the MBTI (form G), and pain threshold or pain tolerance, as measured by the CPT, The findings also indicated a low correlation between pain threshold and pain tolerance (r=.25).

Continuous passive motion (CPM) is a modality used in the treatment, management, and rehabilitation of a variety of orthopedic problems. Recently, CPM devices have been therapeutically employed immediately after autogenous patellar tendon reconstruction of the anterior cruciate ligament (ACL). Whereas the concept of early motion is indicated, there is a concomitant concern that the implementation of immediate passive motion may stretch or rupture the graft. Twenty subjects scheduled to undergo ACL reconstruction were randomized into two groups (10 CPM and 10 non-CPM). All subjects performed the same postoperative rehabilitation with the exception of the CPM. Objective anterior tibial translation measurements were recorded with a KT-1000 for a 30-1b (133.5-N) Lachman test at 1 year postreconstruction. The results of this study indicated that the implementation of immediate continuous passive motion did not have any deleterious effects on the stability of the ligament reconstruction.

The purpose of this investigation was to determine the relationship between ethnicity and acute pain response in male athletes. Subjects included 93 male athletes (age = 18.65 ± .58 years) of differing ethnicity. Each subject performed a Cold Pressor Test (CPT) and was evaluated for pain threshold and pain tolerance times. Two one-way analyses of variance were performed to analyze the data. The results indicated that significant differences existed in pain tolerance times between ethnic groups (p<.05). However, no differences were observed in pain threshold times. These findings support the existence of a difference in pain tolerance between ethnic groups in collegiate athletes.

In an attempt to quantify the current standards in surgical procedures and rehabilitation protocols utilized to treat patients with anterior cruciate ligament (ACL)-deficient knees, a 19-question survey was sent to members of the Hawaii Orthopedic Association. The findings indicated that only 54% (30/56) of the respondents were performing ACL reconstructions, of which 87% (26/30) were performing an intra-articular procedure and none were performing extra-articular procedures exclusively. The findings further indicate that 80% (24/30) of the 30 respondents performing ACL reconstructions were using an arthroscopically assisted, bone-tendon-bone autograft procedure. However, in marked contrast to the uniformity that existed concerning the surgical procedure, there was a drastic difference in the rehabilitation protocols and procedures that were recommended postoperatively. The most apparent differences in rehabilitation protocols existed in the utilization and initiation of open versus closed type kinetic chain exercises and activities.

The purpose of this study was to investigate the differences in skin temperature during ice application through a dry towel and a dry elastic bandage compared to application on bare skin. Nine subjects completed a 30-min treatment session that consisted of 0.68 kg of cubed ice applied under three conditions: through a dry towel, through a dry elastic bandage, and directly on the skin (control). Following the removal of the ice, all subjects were monitored for 20-min for skin temperature (S temp). There was a significant interaction in S temp between the control (12.50 ± 4.39 °C) and dry towel (23.48 ± 2.88 °C) conditions, the control (12.50 ± 4.39 °C) and dry elastic wrap (27.47 ± 2.36 °C) conditions, and the dry towel (23.48 ± 2.88 °C) and dry elastic wrap (27.47 ± 2.36 °C) conditions. The findings indicated that using a barrier (dry towel or dry elastic bandage) limits the temperature-reducing capacity of the ice and therefore its potential physiological effects.
