中尾学人, 山根裕司, 谷口圭吾, 片寄正樹

札幌保健科学雑誌 ( 札幌医科大学保健医療学部 ) ( 8 ) 13 - 20 2019.03 [Refereed]

ジャックナイフストレッチングの即時効果を、脊柱屈曲可動域およびハムストリングスの弾性率に着目して明らかにすることを目的に、健常男性15名(平均年齢26.0±5.4歳)を対象に、ストレッチ実施およびコントロールの2条件における立位体前屈時の指床間距離(FFD)、脊柱屈曲可動域(胸椎、腰椎、骨盤前傾)、ハムストリングス(大腿二頭筋長頭、半腱様筋、半膜様筋)の弾性率を条件の前後にそれぞれ測定した。その結果、ストレッチング介入条件では、FFDおよび骨盤前傾可動域がストレッチ後に有意に増大し、ハムストリングスの弾性率は、ストレッチング後に全ての筋で有意に低い値を示した。これらの結果から、FFDの増大および骨盤前傾可動域の増大は、ハムストリングスの弾性率低下に起因した可能性が示唆された。

Surgical and radiologic anatomy : SRA 41 ( 1 ) 53 - 64 2019.01 [Refereed] [International journal]

PURPOSE: The coupled behavior of talocrural joint motion is primarily determined by the morphological features of the talar trochlea and tibiofibular mortise. Features of the radius of curvature of the talocrural joint, however, remain unclear. The objectives of this study were to evaluate the radius of curvature at the mid, medial, and lateral regions of both the talar trochlea and the tibial plafond, and to estimate subject-specific kinematics of the talocrural joint. METHODS: Computed tomography images of 44 subjects with healthy talocrural joints were assessed by creating three-dimensional bone models. The radii of curvature of the anterior and posterior regions at the mid, medial, and lateral regions of both the talar trochlea and the tibial plafond were calculated. Hypothetical dorsiflexion and plantarflexion axes of the talocrural joint were estimated from the shape of the talar trochlea. Orientations and distances of these axes were calculated. RESULTS: At both the talar trochlea and the tibial plafond, the anteromedial and posteromedial radii exhibited the largest coefficients of variation. The anterior-to-posterior radius ratio (APRR) of the medial talar trochlea significantly correlated with the mid APRR, anterior medial-to-lateral radius ratio (MLRR), and posterior MLRR of the trochlea (r = 0.45, 0.52, - 0.60, respectively, and all P < 0.01). CONCLUSIONS: The asymmetric shape of the medial talar trochlea seems to determine a fixed or changing axis of rotation at the talocrural joint. This subject-specific rotational axis of the talocrural joint should be considered in the management of patients with ankle injuries.

British journal of sports medicine 53 ( 1 ) 32 - 36 2019.01 [International journal]

OBJECTIVES: We describe the medical services provided and report the injuries and illnesses that occurred at the eighth Asian Winter Games 2017. METHODS: A total of 2010 athletes and team officials from 32 National Olympic Committees and 2 guest countries attended this event; medical services were provided for 16 days. Medical data (medical care and physiotherapy) were collected for the same period by the organising committee for athletes and non-athletes (team officials, workforce, media and spectators) and recorded on the electronic medical record system at the medical rooms in the venues and the team residences. RESULTS: We recorded 745 medical encounters (medical care, 443; physiotherapy, 302), of which 549 (74%) were among athletes. There were 214 injuries as well as 144 illnesses and other medical conditions. Of the 1164 athletes, 549 (47%) utilised the services. Ice hockey, snowboarding and alpine skiing had high rate of medical encounters. More than half of the delegations were not accompanied by team doctor, and rate of medical encounters was high in these teams. The vast majority of patients transferred to hospital for further care were mostly athletes (n=36 out of 41), mostly alpine skiers and ice hockey players. CONCLUSION: Injuries and illnesses varied depending on NOC medical staffing and sport events. These data will serve organisers of medical and physiotherapy services in the Asian Winter Games and similar large events.

男女サッカー選手における利き脚・非利き脚による着地動作制御戦略の特徴

青木信裕, 小笠原一生, 片寄正樹

理学療法学Supplement ( 公益社団法人日本理学療法士協会 ) 46 ( 0 ) F - 91-F-91 2019

【はじめに】

サッカーにおける膝前十字靭帯損傷は着地動作時に多発しており，非接触型損傷では男性は利き脚，女性は非利き脚に発生する割合が高いとの報告がある。しかし，動作時の運動力学について左右差を検討している研究は少なく，受傷側の性差が生まれる要因も明らかとなっていない。運動力学の指標の一つである床反力鉛直成分は高い個人特異性を示し，動的バランスを評価できることが示唆されている。本研究では，サッカー選手における着地時の運動力学の性差・左右差を明らかにすることを目的とした。

【方法】

男女サッカー選手を対象とし，利き脚はボールを蹴る脚と定義した。動作課題は20cm台からの前方及び側方への片脚ドロップジャンプ着地とした。計測された床反力鉛直成分から，床反力最大値到達時間（Peak Time）と床反力最大値（Peak Force）を算出し，性別と測定脚を要因とした二元配置分散分析を行った。

【倫理的配慮】

ヘルシンキ宣言に基づき被験者には書面を用いて十分な説明を行い，同意の得られた場合のみ測定を実施した。

【結果】

前方ジャンプでは性差・左右差はなかった。側方ジャンプでは交互作用がみられ，Peak Timeは非利き脚において男性よりも女性の方が短くなり，Peak Forceは女性において利き脚よりも非利き脚で大きくなった。

【考察】

女性でのみ左右差が生じた理由として，女性は男性よりも着地に関する能力が低く，左右差を他の機能で補完できていない可能性がある。

[Purpose] The purpose of this study was to investigate the effects of the plane of arm elevation on the scapulohumeral rhythm of scapular tilt in healthy persons. [Participants and Methods] An optical motion tracking system and acromion marker cluster were used to assess the scapulohumeral rhythm of scapular tilt in the coronal, sagittal and scapular planes during elevation of the arm of fourteen healthy male college students. [Results] The scapulohumeral rhythm of scapular tilt was 1.9 ± 0.4:1 for abduction, 1.8 ± 0.5:1 for scaption, and 1.8 ± 0.4:1 for flexion. During the arm elevation phase, the plane of arm elevation didn’t affect the scapulohumeral rhythm of scapular tilt. [Conclusion] Regardless of the plane of arm elevation, it is possible to use the 2:1 ratio of scapulohumeral rhythm of scapular tilt as a clinical indicator.

Asian spine journal 12 ( 6 ) 1037 - 1042 2018.12 [International journal]

STUDY DESIGN: Retrospective study. PURPOSE: This study aimed to investigate whether segmental lumbar hyperlordosis of the affected vertebra in patients with spondylolysis occurs only at L5 or also occurs at L4. OVERVIEW OF LITERATURE: To the best of our knowledge, increase in segmental lordosis of the spondylolytic vertebrae has only been investigated in bilateral L5 spondylolysis; it has not been examined at different levels of bilateral spondylolysis. According to the characteristics of segmental lordosis in bilateral L5 spondylolysis, patients with bilateral L4 spondylolysis may also have increased segmental lordosis of the L4 vertebra. METHODS: Patients with bilateral spondylolysis of the L5 or L4 vertebra in 2013-2015 were retrospectively identified from the hospital database. Standing lateral lumbar radiographs were assessed for the angle of segmental lordosis of the L5 and L4 vertebra, sacral slope, and lumbar lordosis. The differences in segmental lordosis of the L5 and L4 vertebra, sacral slope, and lumbar lordosis were determined using non-paired Student t-test. RESULTS: Overall, 15 cases of bilateral L4 spondylolysis and 41 cases of bilateral L5 spondylolysis satisfied the inclusion and exclusion criteria. Lordosis of the L4 vertebra was significantly greater in the bilateral L4 spondylolysis group (24.2°±7.0°) than that in the L5 spondylolysis group (20.3°±6.1°, p=0.047). Lordosis of the L5 vertebra was significantly lower in the L4 spondylolysis group (27.7°±8.2°) than that in the L5 spondylolysis group (32.5°±7.3°, p=0.040). The sacral slope and lumbar lordosis did not significantly differ between the groups. CONCLUSIONS: Adolescent patients with bilateral spondylolysis have segmental hyperlordosis of the affected vertebra not only at the L5 level but also at the L4 level.

Masahiro Yoshida, Nobuhiro Aoki, Keigo Taniguchi, Makoto Yoshida, Masaki Katayose

Translational Sports Medicine ( Wiley ) 1 ( 6 ) 265 - 272 2018.11 [Refereed]

The side-hop test (SHT) is useful functional performance test for ankle sprain. However, few research exists to investigate the relationship between the SHT and functional deficit in ankle. The objective of this study was to establish SHT as an evaluation criterion of functional deficits in ankle sprain. Twenty-seven subjects with a history of ankle sprain participated. The time taken to perform SHT in the uninjured and injured limbs was measured. The angular displacements of the ankle joint were measured using the 3D motion analysis system. The muscle activities of the peroneus longus muscle (PL), tibialis anterior muscle (TA), and the medial and lateral gastrocnemius muscles (GM, GL) were measured using surface EMG. The time of SHT in the injured limb (9.22 +/- 1.19 seconds) was significantly longer than that in the uninjured limb (8.71 +/- 0.99 seconds). The range of the ankle inversion/eversion and dorsal flexion/plantar flexion in the injured limb was significantly greater than that in the uninjured limb. The injured limb showed a significant decrease in PL, TA, and GM integral EMG during SHT. Ankle motion and muscle activity caused the decline in SHT time in patients with injured limb.

Acute Effect of Active and Passive Static Stretching on Elastic Modulus of the Hamstrings.

Gakuto Nakao, Keigo Taniguchi, Masaki Katayose

Sports medicine international open 2 ( 6 ) E163-E170 2018.11 [International journal]

The purpose of this study was to investigate differences in the acute effects of passive knee extension (PKE) and active knee extension (AKE) stretching on the shear elastic modulus of the hamstrings. In 20 healthy men, maximum knee extension (maximum range of motion [ROM]) and shear elastic modulus of the hamstrings (biceps femoris long head, semitendinosus, semimembranosus) were measured before (Pre) and after (Post) AKE and PKE stretching. The maximum ROM during stretching was measured. In both stretching methods, maximum ROM increased and the shear elastic modulus decreased (p<0.01), but no difference was found between the procedures. No significant difference was observed in the maximum ROM during stretching between the procedures (p=0.06). The shear elastic modulus was significantly lower in the biceps femoris long head and semimembranosus than in the semitendinosus muscle (p<0.05). Static stretching with PKE and AKE stretching showed an increase in maximum ROM and a decrease in hamstring elasticity, but no difference was found between the methods. Both stretching protocols were effective for reducing elasticity of the biceps femoris long head and semimembranosus.
