Evaluation of Strength and Irradiated Movement Pattern Resulting from Trunk Motions of the Proprioceptive Neuromuscular Facilitation

Introduction. The proprioceptive neuromuscular facilitation (PNF) is a physiotherapeutic concept based on muscle and joint proprioceptive stimulation. Among its principles, the irradiation is the reaction of the distinct regional muscle contractions to the position of the application of the motions.Objective. To investigate the presence of irradiated dorsiflexion and plantar flexion and the existing strength generated by them during application of PNF trunk motions.Methods. The study was conducted with 30 sedentary and female volunteers, the PNF motions of trunk flexion, and extension with the foot (right and left) positioned in a developed equipment coupled to the load cell, which measured the strength irradiated in Newton.Results. Most of the volunteers irradiated dorsal flexion in the performance of the flexion and plantar flexion during the extension motion, both presenting an average force of 8.942 N and 10.193 N, respectively.Conclusion. The distal irradiation in lower limbs became evident, reinforcing the therapeutic actions to the PNF indirect muscular activation.

Category: Hindfoot Introduction/Purpose: Objective: To evaluate and quantify the loss of ankle mobility in patients undergoing subtalar arthrodesis compared to the contralateral side, through physical examination. Methods: A total of 12 patients who had only the subtalar arthrodesis procedure from various causes in one foot were selected. The same foot and ankle surgeon performed all measurements of bilateral tibiotarsal range of motion, with loaded closed-chain and unloaded open-chain tests. Then, to assess whether there was a difference between the operated and the non-operated side, statistical analysis was performed with the Mann-Whitney test (Hollander and Wolfe 1999). Results: On the loaded closed-chain test, the operated side had a significantly lower range of motion than the contralateral side, with a mean difference of 5.4 degrees for dorsal flexion and 7.6 degrees for plantar flexion. The open-chain tests showed non- significant differences of 3 degrees for dorsal flexion and 5.3 degrees for plantar flexion. Conclusion: Subtalar joint arthrodesis was shown to cause a loss of mobility in the ipsilateral ankle, which is greater in plantar flexion movement.

Abstract Background Metatarsophalangeal joint (MTPJ) hyperextension deformity is common in people with diabetic neuropathy and a known risk factor for ulceration and amputation. An MTPJ hyperextension movement pattern may contribute to the development of this acquired deformity. Objective The purpose of this study was to determine, in people with diabetes mellitus and peripheral neuropathy (DM+PN), the ankle and MTPJ ranges of motion that characterize an MTPJ hyperextension movement pattern and its relationship to MTPJ deformity severity. It was hypothesized that severity of MTPJ deformity would be related to limitations in maximum ankle dorsiflexion and increased MTPJ extension during active ankle dorsiflexion movement tasks. Design A cross-sectional study design was used that included 34 people with DM+PN (mean age=59 years, SD=9). Methods Computed tomography and 3-dimensional motion capture analysis were used to measure resting MTPJ angle and intersegmental foot motion during the tasks of ankle dorsiflexion and plantar flexion with the knee extended and flexed to 90 degrees, walking, and sit-to/from-stand. Results The MTPJ extension movement pattern during all tasks was directly correlated with severity of MTPJ deformity: maximum ankle dorsiflexion with knee extended (r=.35; 95% confidence interval [CI]=.02, .62), with knee flexed (r=.35; 95% CI=0.01, 0.61), during the swing phase of gait (r=.47; 95% CI=0.16, 0.70), during standing up (r=.48; 95% CI=0.17, 0.71), and during sitting down (r=.38; 95% CI=0.05, 0.64). All correlations were statistically significant. Limitations This study was cross-sectional, and causal relationships cannot be made. Conclusions A hyperextension MTPJ movement pattern associated with limited ankle dorsiflexion has been characterized in people with diabetic neuropathy. Increased MTPJ extension during movement and functional tasks was correlated with severity of resting MTPJ alignment. Repetition of this movement pattern could be an important factor in the etiology of MTPJ deformity and future risk of ulceration.

Category: Lesser Toes Introduction/Purpose: The purpose of this study was to evaluate the clinical outcomes using a double stemmed flexible silicone prosthesis for the treatment of Freiberg disease in its late stages. Methods: The subjects consisted of 13 feet from 13 cases suffering from Freiberg disease in their late stages. They underwent double stemmed flexible silicone prosthesis replacement for metatarsophalangeal joints. The average age was 63.8 (range 30~88) years. The average follow up period was 26 (range 18–42) months. The investigation was carried out using the range of motion (ROM), visual analog scale (VAS), AOFAS and Maryland metatarsophalangeal joints scale before surgery and at the latest follow-up. Results: The average ROM of dorsal flexion improved from 39.3±6.1° before surgery to 75.4±8.6° at latest follow-up (p<0.001). The average ROM of plantar flexion improved from 19.0±11.4° before surgery to 20.2±9.3° at latest follow-up (p=0.14). The average VAS significantly improved from 8.1±0.5 before surgery to 2.6±0.2 at latest follow-up (p<0.001). The average Maryland metatarsophalangeal joints score significantly improved from 65.3±9.3 points before surgery to 90.3±4.1 points at the latest follow-up (p<0.001). The average AOFAS was 89.4±8.5 after surgery compared 56.3±6.4 preoperatively (p<0.005). Conclusion: A flexible silicone prosthesis replacement was carried out to treat Freiberg disease in its late stages. The function was observed in all cases with improved clinical results. The silicone prosthesis was considered to be useful in certain cases.

INTRODUCTION: The gait in people with HTLV-1 associated myelopathy or tropical spastic paraparesis (HAM / TSP) is little known. OBJECTIVE: To evaluate the kinematic profile of gait in people with HAM/TSP. METHODS: A cross-sectional study with 25 people with HAM/TSP and 25 healthy participants. Spatiotemporal and angular data from filming of gait were submitted to kinematic analysis using CVMob software. The gait of partipants with HAM/TSP was analized quantitatively through t Student test (alpha 5% and Power of 80%). The project was approved by Ethical Committee of the Bahiana School of Medicine and Public Health with CAAE 13568213.8.0000.5544. RESULTS: The HAM/TSP group showed significant changes in two different domains of biomechanical gait analysis when compared to healthy controls. The angular variables showed increased trunk inclination, flexion and extension (p<0.05); increased hip flexion and decreased hip extension (p<0.05); decreased knee flexion and extension (p<0.05); decreased ankle dorsi and plantar flexion (p<0.05). Range of Motion was also reduced in all those joints. The spatiotemporal variables showed decreased stride length and increased stride time and speed gait cycle (p<0.001). Those changes point out to reduction in joint amplitudes of hip, knee and ankle, changes in support base and double support time asymmetry between right and left sides, reduction of pre-swing time, hip lift in the mid-swing, and foot drop throughout the swing. CONCLUSION: People with HAM/TSP have gait characterized by reduction in joint amplitudes of hip, knee and ankle, asymmetry between right and left sides and reduction of pre-swing time, hip lift in the mid-swing, and foot drop throughout the swing.

Gait Kinematics

Abstract Background: Hip osteoarthritis (OA) is a musculoskeletal condition that makes walking difficult due to pain induced by weight-bearing activities. Treadmills that support the body weight (BW) reduce the load on the lower limbs, and those equipped with a lower-body positive-pressure (LBPP) device, developed as a new method for unweighting, significantly reduce pain in patients with knee OA. However, the effects of unweighting on gait kinematics remain unclear in patients with hip OA. Therefore, we investigated the effects of unweighting on kinematics in patients with hip OA during walking on a treadmill equipped with an LBPP device. Methods: A total of 15 women with hip OA and 15 age-matched female controls wore a three-dimensional (3-D) motion analysis system and walked at a self-selected speed on the LBPP treadmill. Data regarding self-reported hip pain using a numeric rating scale (NRS) in which the scores 0 and 10 represented no pain and the worst pain, respectively, under three different BW conditions (100%, 75%, and 50%) were collected. Moreover, 3-D peak joint angles during gait under each condition were calculated and compared. Results: In the hip OA group, the NRS pain scores at 50% and 75% BW conditions significantly decreased compared with that at 100% BW condition (50%, P=0.002; 75%, P=0.026), and the peak hip extension angle decreased compared with that in the healthy controls (P=0.044). In both groups, unweighting significantly decreased the peak hip (P<0.001) and knee (P<0.001) flexion angles and increased the peak ankle plantar flexion angle (P<0.001) during walking. Conclusions: Unweighting by the LBPP treadmill decreased pain in the hip OA group but did not drastically alter the gait kinematics compared with that in the control group. Therefore, regarding the use of the LBPP treadmill for patients with hip OA, clinicians should consider the benefits of pain reduction rather than the kinematic changes.

Abstract The aim of this study was to examine the effects of twelve weeks of resistance training with different exercise orders (upper limbs and lower limbs vs. lower limbs and upper limbs) on flexibility levels in elite judo athletes. Thirtynine male athletes were randomly divided into 3 groups as follows: G1 (n = 13), G2 (n = 13), and CG (n = 13). The flexibility was assessed on 8 joint movements: shoulder flexion and shoulder extension, shoulder abduction and shoulder adduction, trunk flexion and trunk extension, and hip flexion and hip extension. Two-way repeated measures ANOVAs (time [pre-experimental vs. post-experimental] × group [G1 vs. G2 vs. CG]) were used to compare the differences between pre- and post-test situations and the differences among groups. The results from the within-group (pre vs. post) comparisons demonstrated significant increases (p < 0.05) in the range of motion of 3.93 and 5.96% for G1 and G2 training groups, respectively, in all joints. No significant changes (p > 0.05) were observed for the CG. The results from the between-group comparisons demonstrated no significant differences (p > 0.05) in the range of motion between G1post vs. G2post (1.15%). Although both exercise orders (from upper to lower limbs and from lower to upper limbs) increased flexibility, no significant variations were observed between the different exercise orders. Nevertheless, these findings demonstrate that flexibility gains could be obtained with a resistance training program, and thus, more time can be devoted to sports-specific judo training.
