In order to assess the relative efficacy of audio-taped relaxation as compared to live-therapist induced relaxation, 80 volunteer subjects were randomly assigned to one of the following eight groups: (1) live-therapist (male) contingent, (2) live-therapist (male) non-contingent, (3) taped contingent (male), (4) taped non-contingent (male), (5) live-therapist (female) contingent, (6) live-therapist (female) non-contingent, (7) taped (female) contingent, and (8) taped (female) non-contingent. The subjects were exposed to treatment conditions for five sessions during which they received a relaxation sequence via either a live-therapist or audio-taped format in a contingent or non-contingent (subject controlled pace or non-subject controlled pace, respectively) progression. The subjects were monitored with an EMG and Skin Temperature device for 10 minutes following the relaxation sequence. Following the relaxation sequence, each subject was administered a subjective relaxation scale. The first session data were compared to the last session data via a 4 way ANOVA at a .05 alpha level. The analysis of variance indicated that all groups on all of the dependent variables became more relaxed (EMG reduction and skin temperature increase) from pre to post period monitorings. On the variables of EMG and skin temperature, the live-therapist and contingent progression groups produced greater relaxation than did the taped and non-contingent groups. The combination of live-therapist and contingent progression proved to be the most effective in reducing EMG and increasing peripheral skin temperature. (Both indications of relaxation.) All the treatment groups responded similarly on verbal report with the live-therapist contingent and taped-therapist non-contingent groups decreasing most on the verbally reported subjective scale. Implications for the use of live and taped-therapist presentations along with contingent progression formats were discussed.

Denna studie är en kandidatuppsats inom designteknik. Studien görs efter praktik på ett Svenskt företag som producerar arbetskläder. Företaget, som idag är min uppdragsgivare, har ett intresse i att starta egen produktion av produktgruppen 3-lagersjackor. För företaget ses det som en utmaning med produktgruppen, vilket skapade en nyfikenhet hos mig i att utforska ämnet. En 3-lagersjacka kräver tejpning för att bli ett vattentätt plagg, och detta är något som kräver mycket resurser, tid och kunskap. Vid uppstart av ny produktgrupp behöver arbetet starta från grunden med rätt materialval, för att sedan gå vidare till rätt konstruktion och sömnad. Studiens innehåll är vinklat för att undersöka tejpning av 3-lagersmaterial och konstruktion av dess sömmar. Syftet är att ta fram viktigt information- och identifiera vad som är svårt vid tejpning. Studiens resultat bygger till stor del på tester av de tejpade prototyper som skickats för test via ett externt testinstitut. Produktion av produkter bestående av 3-lagersmaterial är beroende av många olika faktorer under både sömnad och konstruktion och blir därför ett brett ämne, men studien har lyckats skrapa lite på ytan och kommit fram till slutsatser som kan vara hjälpsamma vid produktutveckling av 3-lagersprodukter. / This study is a bachelor thesis in design technology. The study is done after an internship at a Swedish company that produces work wear. The company, which today is my client, has an interest in starting its own production of the product group 3-layer jackets. For the company, it is seen as a challenge with the product group, which created a curiosity with me in exploring the subject. A 3-layer jacket requires taping to become a waterproof garment, and this is something that requires a lot of resources, time and knowledge. When starting a new product group, the work needs to start from scratch with the right choice of material, and then move on to the right design and sewing. The content of the study is angled to examine the taping of 3-layer material and the construction of its seams. The purpose is to produce important information and identify what is difficult when taping. The study's results are largely based on tests of the taped prototypes sent for testing via an external test institute. Production of products consisting of 3-layer material is dependent on many different factors during both sewing and construction and therefore becomes a broad subject, but the study has managed to scrape a little on the surface and come to conclusions that can be helpful in product development of 3-layer products.
