Combining extracorporeal shock wave treatment with proprioceptive neuromuscular facilitation can improve the lower limb motor function of stroke survivors with foot drop / 中华物理医学与康复杂志

Objective:To observe any effect of combining extracorporeal shock wave stimulation with proprioceptive neuromuscular facilitation (PNF) on the lower limb motor function of stroke survivors with foot drop.Methods:Thirty-six stroke survivors with foot drop were randomly divided into an extracorporeal shock wave group, a PNF group and a combination group, each of 12. The extracorporeal shock wave group and PNF group were given those therapies alone, while the combination group was provided with both. The extracorporeal shock wave therapy protocol was 2000 times on each muscle at an intensity of 2.5 bar and a frequency of 10Hz, twice a week for 4 weeks, while the PNF was provided at least 3 times per week for 4 weeks. Before and after the intervention, all of the participants were evaluated using the modified Ashworth scale (MAS), the 10-metre walk test (10 MWT) and the Fugl-Meyer lower limb motor function scale (FMA). Active range of the ankle joint and toe out angle were also observed.Results:After the intervention the lower limb muscle tone had decreased significantly in 8 of the PNF group members and in 9 of those in the extracorporeal shock wave group, but it has decreased significantly in all 12 members of the combination group. And the average magnitude of the improvement was also significantly greater in the combination group than in the other two groups. Moreover, significant differences were observed in the active range of the ankle joint after the treatment in the combination group, but not in the other two groups. After the intervention the average 10 MWT times and FMA scores of the PNF and combination groups had improved significantly, but not those of the extracorporeal shock wave group, but significant improvement in toe out angles was observed in all three groups, though the average improvement in the combination group was significantly greater than in the other 2 groups.Conclusion:Combining extracorporeal shock waves with PNF can effectively improve the lower limb motor function of stroke survivors with foot drop.

The acute effect of stretching on eccentrically-damaged muscle: analysis of differences between Hold relax stretching and modified PNF stretching / 体力科学

It is well known that eccentric exercise induces muscle damage that is characterized by a prolonged decrease in muscle strength and range of motion, development of delayed onset muscle soreness. The previous studies showed that hold-relax stretching (HRS) was effective for improving the decreases in range of motion and muscle soreness. In addition, modified proprioceptive neuromuscular facilitation stretching (mPNF) was an equally effective for HRS. However, it was unclear whether there are differences between acute effects of HRS and mPNF on muscle strength and muscle soreness in eccentrically damaged muscle. Therefore, the present study aimed to compare the acute effects of HRS with those of mPNF on muscle strength and soreness in eccentrically damaged muscle. The participants comprised 40 volunteers randomly assigned to either the HRS group (N = 20) or the mPNF group (N = 20). Initially, the participants of both groups performed 60 maximal eccentric contractions of the knee extensors. Two days after this exercise, each group performed either HRS or mPNF for 60 s at a time and repeated them six times for a total of 360 s. Muscle strength and soreness during stretching and contraction were measured before and immediately after HRS and mPNF. The results showed that the muscle soreness observed after eccentric contraction significantly decreased immediately after both HRS and mPNF. In addition, there were no significant changes in muscle strength immediately after both HRS and mPNF. These results suggest that while both HRS and mPNF can effectively decrease muscle soreness without reducing performance.

A Proposed Novel Inhibitor Stretching Procedure For Posterior Shoulder Tightness

Background: Posterior shoulder tightness has been proposed to contribute to or cause a myriad of shoulder conditions. The tightness of the posteroinferior capsule and the teres minor and infraspinatus muscles of the posterior cuff has been hypothesized to cause osteokinematic [e.g., limited glenohumeral (GH) internal rotation] and arthrokinematic dysfunctions (e.g., decentralization of the humeral head). A number of interventions have been successful in the restoration of or at least improvement in posterior shoulder flexibility including joint mobilizations (e.g., posterior glide) and posterior cuff stretches. The two most common posterior cuff stretches, the sleeper stretch and the crossbody stretch, mimic the position of two common impingement Orthopaedic provocation tests. Despite the success of stretching to help optimize tissue extensibility to help prevent injuries, these stretches have been reported to cause pain in some symptomatic subjects. For these reasons, the authors propose creating an alternate posterior shoulder self-stretching technique that facilitates the inhibition of the target region. Aim: Therefore, this paper aims to introduce a novel stretching protocol that utilizes a form of reflex inhibition to help relax the muscle during the stretching procedure to increase efficiency and reduce pain during the stretching maneuver. Underlying Principles for the Proposed Stretching Maneuver: This novel stretch is an active-assisted maneuver using a form of reciprocal inhibition. The authors propose that muscular inhibition through Ia afferents can be applied in a more global manner by muscle contraction of the anatomically remote posterolateral hip cuff musculature (gluteus maximus and medius) to inhibit the target muscles of the posterior rotator cuff of the scapulohumeral joint (infraspinatus and teres minor). This novel inhibitory stretching technique is referred to as Inhibition Stretching (IS), and the specific technique utilized in this study is the Clam Shell Bridging Maneuver. This technique is recommended for overhead athletes with and without shoulder pain and limited GH IR. Summary: The authors have proposed a novel stretching procedure, the Clam Shell Bridging Maneuver, that is hypothesized to reduce the muscles guarding, and resistance of the shoulder girdle during stretching and also position the athlete in a way that helps minimizes pain and impingement during the stretch while still providing stabilization to the scapula.
