Objectives: This non-randomised pilot study investigated the effect of eccentric quadriceps training on 17 patients (22 tendons) with painful chronic patellar tendinopathy.

Methods: Two different eccentric exercise regimens were used by subjects with a long duration of pain with activity (more than six months). (a) Nine consecutive patients (10 tendons; eight men, one woman; mean age 22 years) performed eccentric exercise with the ankle joint in a standard (foot flat) position. (b) Eight patients (12 tendons; five men, three women; mean age 28 years) performed eccentric training standing on a 25° decline board, designed to increase load on the knee extensor mechanism. The eccentric training was performed twice daily, with three sets of 15 repetitions, for 12 weeks. Primary outcome measures were (a) 100 mm visual analogue scale (VAS), where the subject recorded the amount of pain during activity, and (b) return to previous activity. Follow up was at 12 weeks, with a further limited follow up at 15 months.

Results: Good clinical results were obtained in the group who trained on the decline board, with six patients (nine tendons) returning to sport and showing a significantly reduced amount of pain over the 12 week period. Mean VAS scores fell from 74.2 to 28.5 (p = 0.004). At 15 months, four patients (five tendons) reported satisfactory results (mean VAS 26.2). In the standard squat group the results were poor, with only one athlete returning to previous activity. Mean VAS scores in this group were 79.0 at baseline and 72.3 at 12 weeks (p = 0.144).

Conclusion: In a small group of patients with patellar tendinopathy, eccentric squats on a decline board produced encouraging results in terms of pain reduction and return to function in the short term. Eccentric exercise using standard single leg squats in a similar sized group appeared to be a less effective form of rehabilitation in reducing pain and returning subjects to previous levels of activity.

Siblings of young people abusing drugs are at particular risk for drug abuse and other health compromising behaviors. A Sibling Peer Support Group was developed by the Centre for Adolescent Health (Melbourne, Australia) for young people aged 13 to 18 years with a problematic drug user in their family. Groups aimed to provide support and information, promote harm minimization, and reduce the sense of isolation. The project emanated from the recognized need for specific support for adolescent siblings of problematic drug users. Evaluation of two pilot groups indicated positive benefits for group members, who reported feeling better informed, more supported, and having a reduced sense of isolation. Parents reported that their adolescent attending the group demonstrated improved communication with, and greater understanding and tolerance of, the family member using drugs. Promising indicators at a community level were manifested in enthusiastic collaboration among schools, police and local service agencies, and the organization of a local drug forum. There appeared to be little evidence that the groups inadvertently encouraged drug use. Recruitment of young people into groups was the major challenge for the project, but among drug and alcohol and family organizations there was support for the concept of a Sibling Peer Support Group. A new model to overcome the challenge of recruitment is proposed.

This is a methodological study in which a case report is used to retrospectively analyse the link between a successful pilot study and stalled main study to identify potential methodological weaknesses in the planning process. The analysis identified unanticipated influences related to hospital processes and discipline boundaries that adversely influenced participant recruitment and retention for a clinical trial. The findings of the study demonstrate that, whilst the pilot is an important step in research planning to confirm the design and operational processes for a study, a thorough analysis of the relevant health service environment is an important additional objective for the pilot study.

The aims of this study were to examine the utility of various self-report instruments related to family functioning in families where a parent has a psychotic disorder, and to explore associations between these instruments and symptoms in the parent. Twenty-one parents with a psychotic disorders participated in the study. All participants were able to complete the questionnaires and the majority of parents reported levels of parental competence in the average range. Most parents (90%) perceived themselves to be effective parents, however 30% reported low levels of satisfaction with the parenting role. There were significant associations between objective measures of negative symptoms and self-report scores related to problems in ways of coping, and problems with parent-child interactions. Many individuals with psychosis were able to report areas of perceived need related to their role as parents and to the functioning of their families, however there are several limitations in the use of these instruments in this setting.

Traffic Safety Education (TSE) is an important part of a school's program; however, it competes with many other components of schooling such as literacy, numeracy and a number of health areas. Hence TSE provision in Victorian schools has been somewhat fragmented and haphazard in its delivery. This small pilot study involved two metropolitan and two rural schools which attempted to link TSE into mainstream school activities through the new Victorian Essential Learning Standards (VELS) utilising the internationally accepted Health Promoting Schools (HPS) framework.
The findings of the pilot study showed that though schools face many demands, understanding and ownership of TSE is possible when administrative support, professional development and adequate planning time are made available. The report outlines several key recommendations to improve the delivery of Traffic Safety Education in Victorian schools.

Physical attributes of local environments may influence walking. We used a modified version of the Neighbourhood Environment Walkability Scale to compare residents’ perceptions of the attributes of two neighbourhoods that differed on measures derived from Geographic Information System databases. Residents of the high-walkable neighbourhood rated relevant attributes of residential density, land-use mix (access and diversity) and street connectivity, consistently higher than did residents of the low-walkable neighbourhood. Traffic safety and safety from crime attributes did not differ. Perceived neighbourhood environment characteristics had moderate to high test–retest reliabilities. Neighbourhood environment attribute ratings may be used in population surveys and other studies.

Youth substance use related problems are increasingly common, and families experience considerable stress in attempting to cope with these problems. A pilot study of 34 Australian parents from 21 families (38% sole parent families) participating in an 8-week group program, designed to assist families recover from youth substance use related problems, provided the context to explore family change processes. Participants reported a number of significant improvements over the course of the four groups that ran from late 2003 and through 2004. Regression analyses found general support for the program logic model in identifying significant associations between program-targeted parent changes and post-program improvements in stress symptoms and cohesive family behaviors. The study's limitations are noted.

The Internet can access a large number of consumers in a more cost-effective manner than other information delivery channels. In this pilot study, we assessed whether an online weight reduction program including dietary advice plus exercise (ED) was more effective in reducing weight than an exercise-only program (EX) >12 weeks. Participants were randomized to either the ED or EX group and attended a center for anthropometric measurements and dietary assessment. Both groups wore a pedometer and set weekly goals to increase daily steps through an interactive Web site. The ED group set weekly dietary goals via the Web site and received tailored e-mail assistance. Seventy-three participants commenced and 53 (73%) completed the study [EX n = 26; ED n = 27; body mass index—mean (standard deviation): 29.7 (2.5) kg m–2, age 46.3 (10.8); 21% male]. Percent weight changes were EX, 2.1 (0.6)% and ED, 0.9 (0.6)% (P = 0.15). Both groups increased their daily steps with no difference between groups. Only the ED group significantly reduced their energy intake. Despite a greater fall in energy intake reported by the ED group and a similar increase in physical activity in both groups, setting individual dietary goals did not enhance weight loss.

Clinical compression garments have been shown to improve functional control in patients with motor impairments, however, investigation in functional control has not been observed whilst wearing sports compression garments. This pilot study assessed motor control changes in the bicep brachii muscle following a bout of eccentric exercise designed to induce delayed onset muscle soreness for intervals up to 14 days after exercise. Eight male participants performed 35 maximal isokinetic eccentric extensions at 90° s−1. Participants where then randomly divided into one of two groups to perform a one-dimensional elbow flexion/extension visuomotor tracking task; one group wore a sports compression garment during the task, the other acted as control (no garment). The group who wore the compression garment performed the tracking task significantly better immediately post-exercise, and at days 1, 2 and 3 post-exercise (p ≤ 0.05). Non-significant but large and moderate effects sizes (ES), in tracking, were found between the two groups on day 5 (ES = 1.3) and day 7 (ES = 0.7), respectively. Further research is necessary to elucidate these preliminary findings, however, the results suggest that the wearing of sports compression garments post-eccentric exercise has a positive effect on functional motor control.

Background: Chronic painful insertional Achilles tendinopathy is seen in both physically active and non-active individuals. Painful eccentric training, where the patients load the Achilles tendon into full dorsiflexion, has shown good results in patients with mid-portion Achilles tendinosis. However, only 32% of patients with insertional Achilles tendinopathy had good clinical results with that type of eccentric training regimen.

Aim: To investigate whether a new model of painful eccentric training had an effect on chronic painful insertional Achilles tendinopathy.

Patients and methods: 27 patients (12 men, 15 women, mean age 53 years) with a total of 34 painful Achilles tendons with a long duration of pain (mean 26 months), diagnosed as insertional Achilles tendinopathy, were included. The patients performed a new model of painful eccentric training regimen without loading into dorsiflexion. This was done as 3x15 reps, twice a day, 7 days/week, for 12 weeks. Pain during Achilles-tendon-loading activity (VAS) and patient’s satisfaction (back to previous activity) were evaluated.

Results:
At follow-up (mean 4 months) 18 patients (67%, 23/34 tendons) were satisfied and back to their previous tendon-loading activity. Their mean VAS had decreased from 69.9 (SD 18.9) to 21 (SD 20.6) (p<0.001). Nine patients (11 tendons) were not satisfied with the treatment, although their VAS was significantly reduced from 77.5 (8.6) to 58.1 (14.8) (p<0.01).

Conclusion:
In this short-term pilot study this new model of painful eccentric calf-muscle training showed promising clinical results in 67% of the patients.

Mediums claim to be able to report accurate and specific information about the deceased loved ones (termed discarnates) of living people (termed sitters) even without any prior knowledge about the sitters or the discarnates and in the complete absence of any sensory feedback. Despite recent proof-focused experimental research investigating this phenomenon (e.g., Beischel & Schwartz, 2007), no published studies have attempted to quantify the phenomenological effects of discarnate readings. The aim of the present study was, thus, to investigate experimentally the phenomenological differences that arose psychologically in accordance with the demands of a discarnate reading task versus a control task. Seven mediums were administered counter-balanced sequences of a discarnate reading and control condition. The discarnate reading condition consisted of a phone reading including questions about a discarnate where only a blinded medium and a blinded experimenter were on the phone. The control condition consisted of a phone conversation between the medium and the same experimenter in which the medium was asked similar questions regarding a living person s/he (i.e., the medium) knew. Mediums’ phenomenology during each condition was retrospectively assessed using the Phenomenology of Consciousness Inventory (PCI). Phenomenology associated with the discarnate reading condition appeared to be significantly different from phenomenology associated with the control condition. Future research might use the PCI to address whether the phenomenology reported by mediums during discarnate readings is quantitatively different from their experiences during psychic telepathy readings for the living.

The acute decision prompting effects of social marketing via television (TV) advertisements promoting physical activity to children are unknown. This pilot study aimed to determine the acute effects of an Australian government-sponsored TV advertisement (called ‘Get Moving’), promoting more physical activity and less sedentary behaviour, on children's choices, preferences, and ratings of liking for physical activities and sedentary behaviours. Thirty-one children aged 10–12 years were recruited from a single public school, and randomised to one of two treatment groups or two control groups (Solomon four-group design). Treatment participants watched an episode of The Simpsons® embedded every 10 min with three 30 s Get Moving advertisements plus standard advertisements. Control participants watched the same episode plus standard advertisements, but without the Get Moving advertisements. The following dependent variables were assessed immediately before and/or after exposure: activity preference (participants selected either verbally or by pointing to one of eight picture cards depicting four physical activities and four sedentary behaviours); ratings of liking (participants rated how much they liked or disliked each of these activities/behaviours either verbally or by pointing to one of nine values with an adjacent smile or frown on a Likert-type scale); and time spent in physical activities was assessed by direct observation during a 10 min free-time session. No significant effects or trends were seen for any of the dependent variables. Further research is needed to determine whether different content and/or higher doses of exposure to physical activity promoting advertisements are needed to influence children's activity choices.
