“…For instance, in the conservative treatment of leprous neuritis, a protective splint is usually molded in plaster of Paris in the volar aspect of the upper extremities or the posterior (plantar) aspect of the lower extremities, aiming to keep the segment and nerve temporarily in a resting position 18 . Splinting can be used in the rehabilitation of flexor tendon repair; fracture and for low load application for stimulating slow growth but not damaging tissues 9,19 . Wytch et al 12 reported that the incidence of breaks of plaster of Paris splints is a concerning matter.…”

“…Joint stiffness is a complication following traumatic hand injury that results from the combined effects of inflammation and immobilisation (Innis, Clark and Curtis 1995, Bell-Krotoski and Figarola 1995, Reynolds et al 1996. It has been defined as the resistance to motion that a joint provides throughout available range (Roberson andGiurintano 1995, Lee 1998).…”

The principal aim of this study was to examine aspects of the reliability and validity of the Torque Angle Curve (TAC) technique as a measure of joint stiffness. Specifically, inter-rater and intra-rater reliability were examined as well as the percent agreement of therapist evaluation of joint 'end feel' (i.e. springy or non-springy). Convergent validity of the TAC technique was studied by assessing the extent of agreement between TAC scores and therapist ratings of end feel. Thirty-eight joints were assessed in 24 subjects. Inter-rater reliability ICC (2,2) of the TAC technique was .80 and intra-rater reliability ICC (3,1) was .76 for rater A and ICC (3,1) .64 for rater B. Percent agreement for the end-feel technique was 68.4% with Kappa = .42. A significant difference was found between TAC scores for springy joints (mean [SD] 12.0˚ [3.7]) and TAC scores for non-springy joints (mean [SD] 7.2˚ [2.8]), when raters agreed on end feel (p = .000). When raters did not agree on end feel, the mean TAC score was 9.6˚ [2.2]. Results from this preliminary investigation suggest that the TAC technique provides a more reliable estimate of joint stiffness than the use of end feel. Further research with a larger sample size is required to replicate findings.

“…The research results reported in the past have already confirmed a possibility that lowload, long-lasting tension is effective to encourage growth of connective tissues and could be a useful treatment for a fixed joint contracture (Bell-Krotoski andFigarola 1995, Flowers andLaStayo 1994). For further improvement of treatment, a new corrective device and therapeutic equipment will be required on the basis of a quantitative understanding about pathological mechanisms of contracture development in relation to mechanical stress (Brand 1995).…”

The purpose of this study was to clarify the relationship between mechanical stress and tissue response of the contracted knee joint in rats and to propose a new design of contracture correction device for clinical use. Wistar rats were operated on to immobilize their knee joints with a procedure causing periarticular bleeding and were kept in flexed position for 40 days. At day 40, the immobilizing wire was removed, and after day 43, the contracted knee joint had been treated with tunable corrective devices secured by an external fixation method to the rear limb. These devices consisted of four types of motor-driving system which provided several different low-load and continuous stretch torques. Measuring the angle of maximum knee extension, its effectiveness was assessed comparing with a lower load and control group of natural recovery course. The device also had a cyclic joint movement within the acquired range of motion and an oval cam mechanism producing a small distraction force to the joint along its long axis. The results showed that an appropriate range of low-load continuous torque was more effective to correct joint contracture. On the basis of the animal experiment, a new computer-controlled, gas-driven contracture correction device was developed for clinical trial. It was concluded that mechanical application in a condition with low and continuous torque is a useful treatment for fixed joint contracture.
